Save Changed Objects (SAVCHGOBJ)

Where allowed to run: All environments (*ALL)
Threadsafe: No 		Parameters
Examples
Error messages

The Save Changed Object (SAVCHGOBJ) command saves a copy of each changed object or group of objects located in the same library. When *ALL is specified for the Objects (OBJ) parameter, objects can be saved from all user libraries or from a list of libraries. When saving to a save file, only one library can be specified. For database files, only the changed members are saved.

Objects changed since the specified date and time are saved with the following exceptions:

Specified objects that were changed and the libraries where they reside remain locked during the save operation.

Saved objects can be restored with the Restore Object (RSTOBJ) command.

To determine the date and time that an object was changed, run the Display Object Description (DSPOBJD) command with DETAIL(*FULL) specified. For database file members that were changed, run the Display File Description (DSPFD) command.

The types of objects that can be saved by this command are listed in the OBJTYPE parameter description in "Commonly used parameters: Expanded descriptions" in the CL concepts and reference topic in the iSeries Information Center at http://www.ibm.com/eserver/iseries/infocenter. The system saves the changed objects by writing a copy of each one on tapes, optical volumes, or a save file. The description of each object is changed with the date, time, and place when it was last saved and is controlled by the UPDHST parameter.

This command ignores all file overrides currently in effect for the job except for the save output file.

Objects (OBJ)

Specifies the names of one or more objects, or the generic names of each group of objects, to check for changes and then to save those objects that have changed. All the objects must be in the library specified for the Library (LIB) parameter. If *ALL is specified or defaulted for the Object types (OBJTYPE) parameter, all the object types listed in the description of that parameter are saved, provided they are in the specified library and have the specified names.

This is a required parameter.

Single values

*ALL

All changed objects in the specified libraries are saved, depending on the values specified for the OBJTYPE parameter.

Other values (up to 300 repetitions)

generic-name

Specify one or more generic names of groups of changed objects to save in the specified library. A generic name is a character string that contains one or more characters followed by an asterisk (*). If an * is not specified with the name, the system assumes that the name is a complete object name.

name

Specify the names of specific objects to save. Both generic names and specific names can be specified in the same command.

Top

 

Library (LIB)

Specifies the library that contains the changed objects to be saved.

Libraries are saved alphabetically by ASP device name for each value specified. Libraries on independent ASPs are saved before libraries on the system and basic user ASPs. For value *ALLUSR, libraries QSYS2, QGPL, QUSRSYS, and QSYS2xxxxx (where xxxxx is an independent ASP number) are saved first, if they are located on the ASPs specified by the ASPDEV parameter.

This is a required parameter.

Single values

*ALLUSR

All user libraries are saved. All libraries with names that do not begin with the letter Q are saved except for the following: 

 #CGULIB     #DSULIB     #SEULIB #COBLIB     #RPGLIB #DFULIB     #SDALIB

Although the following Qxxx libraries are provided by IBM, they typically contain user data that changes frequently. Therefore, these libraries are considered "user libraries", and are also saved: 

 QDSNX       QRCLxxxxx   QUSRIJS     QUSRVxRxMx QGPL        QSRVAGT     QUSRINFSKR QGPL38      QSYS2       QUSRNOTES QMGTC       QSYS2xxxxx  QUSROND QMGTC2      QS36F       QUSRPOSGS QMPGDATA    QUSER38     QUSRPOSSA QMQMDATA    QUSRADSM    QUSRPYMSVR QMQMPROC    QUSRBRM     QUSRRDARS QPFRDATA    QUSRDIRCL   QUSRSYS QRCL        QUSRDIRDB   QUSRVI

A different library name, in the format QUSRVxRxMx, can be created by the user for each previous release supported by IBM to contain any user commands to be compiled in a CL program for the previous release. For the QUSRVxRxMx user library, VxRxMx is the version, release, and modification level of a previous release that IBM continues to support.

*USRSPC

The libraries identified in the user space specified for the Command user space (CMDUSRSPC) parameter are saved. Only one library can be specified in the user space when saving to a save file. Special value *SPLF cannot be specified in the user space.

Other values (up to 300 repetitions)

generic-name

Specify the generic name of the library. A generic name is a character string of one or more characters followed by an asterisk (*); for example, ABC*. The asterisk (*) substitutes for any valid characters. A generic name specifies all libraries with names that begin with the generic prefix, for which the user has authority. If an asterisk is not included with the generic (prefix) name, the system assumes it to be the complete library name. A generic library name cannot be specified when saving to a save file.

name

If *ALL is specified for the Objects (OBJ) parameter, up to 300 library names can be specified. Only one library can be specified when saving to a save file.

Top

 

Device (DEV)

Specifies the name of the device used for the save operation. The device name must already be known on the system by a device description.

This is a required parameter.

Single values

*SAVF

The save operation is done using the save file specified for the Save file (SAVF) parameter.

*MEDDFN

The save operation is done using the devices and media identified in the media definition specified for the Media definition (MEDDFN) parameter.

Other values

optical-device-name

Specify the name of the optical device used for the save operation.

tape-media-library-device-name

Specify the name of the tape media library device used for the save operation.

tape-device-name

Specify the names of one or more tape devices used for the save operation. If a virtual tape device is used, it must be the only device specified. If multiple tape devices are used, they must have compatible media formats and their names must be specified in the order in which they are used. Using more than one tape device permits one tape volume to be rewound and unloaded while another tape device processes the next tape volume. To use more than one device in parallel, a media definition must be specified.

Top

 

Object types (OBJTYPE)

Specifies the types of system objects whose changes are saved. The object types saved are also the ones saved and restored by the Save Library (SAVLIB), Restore Object (RSTOBJ), and Restore Library (RSTLIB) commands. Data dictionaries and the associated files are saved only by using the SAVLIB command.

Single values

*ALL

Changes to all object types that are specified by name, and which are in the specified library, are saved.

Other values (up to 300 repetitions)

object-type

Specify the value for each of the types of objects that are saved, such as command (*CMD), file (*FILE), or program (*PGM).

To see a complete list of object types when prompting this command, position the cursor on the field for this parameter and press F4 (Prompt). For a description of the object types, see "Object types" in the CL concepts and reference topic in the iSeries Information Center at http://www.ibm.com/eserver/iseries/infocenter.

Top

 

Journaled objects (OBJJRN)

Specifies whether to save changed objects that are currently being journaled and that have been journaled since the date and time specified for the Reference date (REFDATE) and Reference time (REFTIME) parameters.

*NO

Objects being journaled are not saved. If journaling was started after the specified date and time, the changed objects or changed database file members are saved. The date and time of the last journal start operation can be shown by using the Display Object Description (DSPOBJD) command.

*YES

Objects whose changes are entered in a journal are saved.

Top

 

Reference date (REFDATE)

Specifies the reference date. Objects that have been changed since this date are saved.

*SAVLIB

The objects that have been changed since the date of the last running of the Save Library (SAVLIB) command are saved. If the specified library was never saved, a message is issued and the library is not saved, but the operation continues.

date

Specify the reference date; objects that have been changed since this date are saved. If you specify a date later than the date of the running of this command, a message is issued and the operation ends. The date must be specified in the job date format.

Top

 

Reference time (REFTIME)

Specifies the reference time. Objects that have been changed since this time on the specified date are saved.

*NONE

No explicit time is specified. Any objects changed since the date specified for the Reference date (REFDATE) parameter are saved.

time

Specify the reference time; objects that have been changed since this time on the specified date are saved. If *SAVLIB is specified for the REFDATE parameter, no reference time can be specified. If you specify a time later than the time of the running of this command, a message is issued and the operation ends.

The time can be specified with or without a time separator:

  • Without a time separator, specify a string of 6 digits (hhmmss) where hh = hours, mm = minutes, and ss = seconds.

  • With a time separator, specify a string of 8 digits where the time separator specified for your job is used to separate the hours, minutes, and seconds. If you enter this command from the command line, the string must be enclosed in apostrophes. If a time separator other than the separator specified for your job is used, this command will fail.

Top

 

Volume identifier (VOL)

Specifies the volume identifiers of the volumes, or the cartridge identifiers of tapes in a tape media library device, on which the data is saved. The volumes must be placed in the device in the same order as specified for this parameter.

Single values

*MOUNTED

The data is saved on the volumes placed in the device. For a media library device, the volume to be used is the next cartridge in the category mounted by the Set Tape Category (SETTAPCGY) command.

This value cannot be specified when using an optical media library device.

Other values (up to 75 repetitions)

character-value

Specify the identifiers of one or more volumes in the order in which they are placed in a device and used to save the data.

Top

 

Sequence number (SEQNBR)

Specifies, when tape is used, the sequence number to use as the starting point for the save operation.

*END

The save operation begins after the last sequence number on the first tape. If the first tape is full, an error message is issued and the operation ends.

1-16777215

Specify the sequence number of the file to be used for the save operation.

Top

 

Label (LABEL)

Specifies the name that identifies the data file on the tape volume that is to be used for the save operation. If this parameter is used on the save command, the same label must be specified on the restore command.

You cannot specify *SAVLIB on this parameter, since it is a special value for the Label (LABEL) parameter of the restore command and would prevent you from restoring what you saved.

*LIB

The file label is created by the system using the name of the library specified for the Library (LIB) parameter.

character-value

Specify the data file identifier of the data file used for the save operation. A maximum of 17 characters can be used. This option is valid only for a single-library save operation.

Top

 

File expiration date (EXPDATE)

Specifies the expiration date of the file created by the save operation. If a date is specified, the file is protected and cannot be overwritten until the specified expiration date.

Notes:

  1. This parameter is valid for tape and optical files.

  2. Specifying this parameter does not protect against a later save operation specifying CLEAR(*ALL).

*PERM

The file is protected permanently.

date

Specify the date when protection for the file ends.

Top

 

End of media option (ENDOPT)

Specifies the operation that is automatically done on the tape or optical volume after the save operation ends. If more than one volume is used, this parameter applies only to the last volume used; all other volumes are unloaded when the end of the volume is reached.

This parameter is valid only if a tape or optical device name is specified for the DEV parameter. For optical devices, *UNLOAD is the only special value supported, *REWIND and *LEAVE will be ignored.

*REWIND

The tape is automatically rewound, but not unloaded, after the operation has ended.

*LEAVE

The tape does not rewind or unload after the operation ends. It remains at the current position on the tape drive.

*UNLOAD

The tape is automatically rewound and unloaded after the operation ends. Some optical devices will eject the volume after the operation ends.

Top

 

Starting library (STRLIB)

Specifies the library with which to begin the save operation.

If an unrecoverable media error occurs during the save operation, this parameter can be used to restart the operation.

The basic steps for restarting a save operation are:

  1. Check the job log to determine the library where the previous save operation failed. Find the last library saved, which is indicated by a successful completion message.

  2. Load the next tape and ensure the tape is initialized.

  3. Add the following to your original save command: 

       STRLIB(library-name)  OMITLIB(library-name)

    where the library-name for the STRLIB and OMITLIB parameters is the last library successfully saved. This starts the save operation on the library after the last successfully saved library.

    To restore the libraries, you will need to perform a separate restore operation for each save operation that was performed.

*FIRST

The save operation begins with the first library value specified for the Library (LIB) parameter. If the first value is a generic name or special value, the save operation begins with the first library that matches this value.

name

Specify the name of the library with which to begin the save operation.

Top

 

Save file (SAVF)

Specifies the save file that is used to contain the saved data. The save file must be empty, unless *ALL is specified for the Clear (CLEAR) parameter.

A value must be specified for this parameter if *SAVF is specified for the Device (DEV) parameter.

Qualifier 1: Save file

name

Specify the name of save file to be used.

Qualifier 2: Library

*LIBL

All libraries in the library list for the current thread are searched until the first match is found.

*CURLIB

The current library for the thread is used to locate the save file. If no current library entry exists in the library list, the QGPL library is used.

name

Specify the name of the library where the save file is located.

Top

 

Media definition (MEDDFN)

Specifies the media definition (*MEDDFN) object that identifies the devices and media used to contain the saved data. For information about creating and using a media definition, see the Backup and Recovery book, SC41-5304, and the Create Media Definition API in the System API Reference information in the iSeries Information Center at http://www.ibm.com/eserver/iseries/infocenter.

If a media definition is specified, the VOL, SEQNBR, SAVF, and OPTFILE parameters cannot be specified. The volume identifiers and sequence numbers are specified in the media definition.

Qualifier 1: Media definition

name

Specify the name of the media definition to be used.

Qualifier 2: Library

*LIBL

All libraries in the library list for the current thread are searched until the first match is found.

*CURLIB

The current library for the thread is searched. If no library is specified as the current library for the thread, the QGPL library is searched.

name

Specify the name of the library to be searched.

Top

 

Optical file (OPTFILE)

Specifies the path name of the optical file that is used for the save operation, beginning with the root directory of the volume.

For more information on specifying path names, refer to "Object naming rules" in the CL concepts and reference topic in the iSeries Information Center at http://www.ibm.com/eserver/iseries/infocenter.

*

The system generates an optical file name in the root directory of the optical volume.

'optical-directory-path-name/*'

The system generates an optical file name in the specified directory of the optical volume.

'optical-file-path-name'

Specify the path name of the optical file.

Top

 

Use optimum block (USEOPTBLK)

Specifies whether or not the optimum block size is used for the save operation.

Specifying USEOPTBLK(*YES) may result in a tape that can be duplicated only to a device that supports the same block size.

*YES

The optimum block size supported by the device is used for Save commands. If the block size that is used is larger than a block size that is supported by all device types, then:

  • Performance may improve.

  • The tape file that is created is only compatible with a device that supports the block size used. Commands such as Duplicate Tape (DUPTAP) do not duplicate files unless the files are being duplicated to a device which supports the same block size that was used.

  • The value for the DTACPR parameter is ignored.

*NO

The optimum block size supported by the device is not used. Save commands use the default block size supported by all device types. The tape volume can be duplicated to any media format using the Duplicate Tape (DUPTAP) command.

Top

 

Target release (TGTRLS)

Specifies the release of the operating system on which you intend to restore and use the object.

When specifying the target-release value, the format VxRxMx is used to specify the release, where Vx is the version, Rx is the release, and Mx is the modification level. For example, V5R3M0 is version 5, release 3, modification 0.

Valid values depend on the current version, release, and modification level of the operating system, and they change with each new release. You can press F4 while prompting this command parameter to see a list of valid target release values.

To specify that an object be saved for distribution to a system at a different release level than the system on which the save operation is to occur, the procedure differs for program or non-program objects and by the release level on which a program object is created. If, for example, you are saving an object for distribution to a target system running on an earlier release, you have the following choices:

For program objects:

For non-program objects:

You can:

  1. save the object specifying the targeted earlier release

  2. restore the object on the target system.

*CURRENT

The object is to be restored to, and used on, the release of the operating system currently running on your system. The object can also be restored to a system with any subsequent release of the operating system installed.

*PRV

The object is to be restored to the previous release with modification level 0 of the operating system. The object can also be restored to a system with any subsequent release of the operating system installed.

character-value

Specify the release in the format VxRxMx. The object can be restored to a system with the specified release or with any subsequent release of the operating system installed.

Notes:

  1. If LIB(*ALLUSR) is specified, only the current release can be the target release.

  2. Not all objects can be targeted to another release. To find out which objects are supported, see the chart in the Backup and Recovery book, SC41-5304.

Top

 

Update history (UPDHST)

Specifies whether the save history information of each saved object is changed with the date, time, and location of this save operation. The save history information for an object is displayed using the Display Object Description (DSPOBJD) command. The save history information is used to determine which journal entries are processed when RCVRNG(*LASTSAVE) and FROMENT(*LASTSAVE) or FROMENTLRG(*LASTSAVE) are used on the Apply Journaled Changes (APYJRNCHG) command.

*YES

The last save date, time, and location is updated in each object saved.

*NO

The save history information contained in the description of each object saved is not updated.

UPDHST(*NO) should be used for a save operation that is not intended for recovery. For example, if the save data is sent, record by record, to another system and the save file immediately deleted, the save history information is probably not to be updated.

Top

 

Clear (CLEAR)

Specifies whether active data on the media is automatically cleared or replaced. Active data is any file on the media that has not expired. For saves to tape, clearing active data will make any files on the tape volume beyond the last file written by the save operation no longer accessible. For saves to optical, the files written by the save operation can be automatically replaced while other files on the volume remain active, or all active files can be automatically cleared. Clearing does not erase the data, it just makes the files no longer accessible.

Notes:

  1. Clearing a tape does not initialize it. You should initialize tapes to a standard label format before the save command is issued by using the Initialize Tape (INZTAP) command and specifying a value for the NEWVOL parameter.

  2. Clearing an optical volume does initialize it.

  3. If a volume that is not initialized is encountered during the save operation, an inquiry message is sent and an operator can initialize the volume.

*NONE

None of the media is automatically cleared. If the save operation encounters active data on a tape volume or in a save file, an inquiry message is sent, allowing the operator to either end the save operation or clear the media. If the save operation encounters the specified optical file, an inquiry message is sent, allowing the operator to either end the save operation or replace the file.

*ALL

All of the media is automatically cleared.

If tapes are used and a sequence number is specified for the SEQNBR parameter, the first tape is cleared beginning at that sequence number. All tapes following that first tape are completely cleared. To clear the entire first tape, SEQNBR(1) must be specified.

*AFTER

All media after the first volume is automatically cleared. If the save operation encounters active data on the first tape volume, an inquiry message is sent, allowing the operator to either end the save operation or clear the media. If the save operation encounters the specified optical file on the first volume, an inquiry message is sent, allowing the operator to either end the save operation or replace the file.

The *AFTER value is not valid for save files.

*REPLACE

Active data on the media is automatically replaced. Optical volumes are not initialized. Other media is automatically cleared in the same way as the *ALL value.

Top

 

Object pre-check (PRECHK)

Specifies whether the save operation for a library ends if any of the following are true:

  1. The objects do not exist

  2. The library or the objects were previously found to be damaged

  3. The library or the objects are locked by another job

  4. The requester of the save operation does not have authority for the library or to save the objects.

*NO

The save operation for a library continues, saving only those objects that can be saved.

*YES

If, after all specified objects are checked, one or more objects cannot be saved, the save operation for a library ends before any data is written. If multiple libraries are specified, the save operation continues with the next library. However, if PRECHK(*YES) and SAVACT(*SYNCLIB) are specified and an object in any library to be saved does not meet the preliminary check conditions, the save operation ends and no objects are saved.

Top

 

Save active (SAVACT)

Specifies whether an object can be updated while it is being saved.

If your system is in a restricted state and the SAVACT parameter is specified, the save operation is performed as if SAVACT(*NO) was specified.

*NO

Objects that are in use are not saved. Objects cannot be updated while being saved.

*LIB

Objects in a library can be saved while they are in use by another job. All of the objects in a library reach a checkpoint together and are saved in a consistent state in relationship to each other.

*SYNCLIB

Objects in a library can be saved while they are in use by another job. All of the objects and all of the libraries in the save operation reach a checkpoint together and are saved in a consistent state in relationship to each other.

If you specify this value and you are saving many libraries, it can take a long time to reach a checkpoint for all of the objects and libraries in the save operation.

*SYSDFN

Objects in a library can be saved while they are in use by another job. Objects in a library may reach checkpoints at different times and may not be in a consistent state in relationship to each other.

Top

 

Save active wait time (SAVACTWAIT)

Specifies the amount of time to wait for an object that is in use, or for transactions with pending changes to reach a commit boundary, before continuing the save operation.

Element 1: Object locks

For each object that is in use, specifies the amount of time to wait for the object to become available. If an object remains in use for the specified time, the object is not saved.

120

The system waits up to 120 seconds for each individual object lock before continuing the save operation.

*NOMAX

No maximum wait time exists.

0-99999

Specify the number of seconds to wait for each individual object lock before continuing the save operation.

Element 2: Pending record changes

For each group of objects that are checkpointed together, specifies the amount of time to wait for transactions with pending record changes to reach a commit boundary. The Save active (SAVACT) parameter determines which objects are checkpointed together. If 0 is specified, all objects being saved must be at commit boundaries. If any other value is specified, all objects that are journaled to the same journals as the objects being saved must reach commit boundaries. If a commit boundary is not reached in the specified time, the save operation is ended, unless the value *NOCMTBDY is specified.

*LOCKWAIT

The system waits up to the value specified for Element 1 for transactions with pending record changes to reach a commit boundary.

*NOCMTBDY

The system will save objects without requiring transactions with pending record changes to reach a commit boundary. Therefore, objects may be saved with partial transactions.

If you restore an object that was saved with partial transactions, you cannot use the object until you apply or remove journal changes (APYJRNCHG or RMVJRNCHG command) to reach commit boundaries. You will need all journal receivers that contain information about the partial transactions to apply or remove the changes. Until you apply or remove the changes, any future save of that object will include the partial transactions, even if you do not specify *NOCMTBDY.

This value cannot be specified if the Target release (TGTRLS) parameter value is earlier than V5R3M0.

*NOMAX

No maximum wait time exists.

0-99999

Specify the number of seconds to wait for transactions with pending record changes to reach a commit boundary.

Element 3: Other pending changes

For each library, specifies the amount of time to wait for transactions with other pending changes to reach a commit boundary. Other pending changes include the following:

If a commit boundary is not reached for a library in the specified time, the library is not saved.

*LOCKWAIT

The system waits up to the value specified for Element 1 for the types of transactions that are listed above to reach a commit boundary.

*NOMAX

No maximum wait time exists.

0-99999

Specify the number of seconds to wait for the types of transactions that are listed above to reach a commit boundary.

If 0 is specified, and only one name is specified for the Objects (OBJ) parameter, and *FILE is the only value specified for the Object types (OBJTYPE) parameter, the system will save the object without requiring the types of transactions that are listed above to reach a commit boundary.

Top

 

Save active message queue (SAVACTMSGQ)

Specifies the message queue that the save operation uses to notify the user that the checkpoint processing for a library is complete. A separate message is sent for each library to be saved when the *SYSDFN or *LIB value is specified for the Save active (SAVACT) parameter. When *SYNCLIB is specified for the SAVACT parameter, one message is sent for all libraries in the save operation.

This parameter can be used to save the objects at a known, consistent boundary to avoid additional recovery procedures following a restore operation. Applications can be stopped until the checkpoint processing complete message is received.

Single values

*NONE

No notification message is sent.

*WRKSTN

The notification message is sent to the work station message queue. This value is not valid in batch mode.

Qualifier 1: Save active message queue

name

Specify the name of the message queue to be used.

Qualifier 2: Library

*LIBL

All libraries in the library list for the current thread are searched until the first match is found.

*CURLIB

The current library for the job is used to locate the message queue. If no library is specified as the current library for the job, the QGPL library is used.

name

Specify the name of the library where the message queue is located.

Top

 

Save access paths (ACCPTH)

Specifies whether the logical file access paths that are dependent on the physical files being saved are also saved. The access paths are saved only in the case of the following:

The system checks to ensure the integrity of the access paths. Any discrepancies found by the system will result in the access paths being rebuilt.

Informational messages are sent indicating the number of logical file access paths saved with each physical file. All physical files on which an access path is built must be in the same library. This parameter does not save logical file objects; it only controls the saving of the access paths. More information on the restoring of saved access paths is in the Backup and Recovery book, SC41-5304.

ATTENTION: If the based-on physical files and the logical files are in different libraries, the access paths are saved. However, if the logical files and the based-on physical files are in different libraries and the logical files or physical files do not exist at restore time (such as during disaster recovery or the files were deleted) the access paths are not restored. They are rebuilt. For the fastest possible restore operation for logical files, the logical files and the based-on physical files must be in the same library and must be saved at the same time.

*SYSVAL

The QSAVACCPTH system value determines whether to save the logical file access paths that are dependent on the physical files that are being saved.

*NO

Only those objects specified on the command are saved. No logical file access paths are saved.

*YES

The specified physical files and all eligible logical file access paths over them are saved.

Specifying this value does not save the logical files.

Save file data (SAVFDTA)

Specifies, for save file objects, whether the description of a save file, or both the description and the contents of a save file, are saved.

*YES

The description and contents of a save file are saved.

*NO

Only the description of a save file is saved.

Top

 

Queue data (QDTA)

Specifies, for queue objects, whether the description of a queue, or both the description and the contents of a queue, are saved.

*NONE

Only the description of a queue is saved.

*DTAQ

The description and contents of a standard data queue are saved. Only the description of a Distributed Data Management (DDM) data queue is saved.

Top

 

Data compression (DTACPR)

Specifies whether data compression is used. If the save is running while other jobs on the system are active and software compression is used, the overall system performance may be affected.

If *DEV is specified for both this parameter and the Data compaction (COMPACT) parameter, only device data compaction is performed if device data compaction is supported on the device. Otherwise, data compression is performed.

If *YES is specified for this parameter and *DEV is specified for the COMPACT parameter, both device data compaction and device data compression are performed if supported on the device.

*DEV

If the save is to tape and the target device supports compression, hardware compression is performed. Otherwise, no data compression is performed.

*NO

No data compression is performed.

*YES

If the save is to tape and the target device supports compression, hardware compression is performed. If compression is not supported, or if the save data is written to optical media or to a save file, software compression is performed. Low software compression is used for all devices except optical DVD, which uses medium software compression.

*LOW

If the save operation is to a save file or optical, software data compression is performed with the SNA algorithm. Low compression is usually faster and the compressed data is usually larger than if medium or high compression is used.

This value is not valid for tape.

*MEDIUM

If the save operation is to a save file or optical, software data compression is performed with the TERSE algorithm. Medium compression is usually slower than low compression but faster than high compression. The compressed data is usually smaller than if low compression is used and larger than if high compression is used.

This value is not valid for tape.

*HIGH

If the save operation is to a save file or optical, software data compression is performed with the LZ1 algorithm. High compression is usually slower and the compressed data is usually smaller than if low or medium compression is used.

This value is not valid for tape.

Data compaction (COMPACT)

Specifies whether device data compaction is performed.

*DEV

Device data compaction is performed if the data is saved to tape and all tape devices specified for the Device (DEV) parameter support the compaction feature.

If *DEV is specified for both the Data compression (DTACPR) parameter and this parameter, only device data compaction is performed if device data compaction is supported on the device. Otherwise, data compression is performed if supported on the device.

If *YES is specified for the DTACPR parameter and *DEV is specified for this parameter, both device data compaction and device data compression are performed if supported on the device.

*NO

Device data compaction is not performed.

generic-name

Specify the generic name of the libraries to be excluded. A generic name is a character string of one or more characters followed by an asterisk (*); for example, ABC*. The asterisk (*) substitutes for any valid characters. A generic name specifies all libraries with names that begin with the generic prefix, for which the user has authority. If an asterisk is not included with the generic (prefix) name, the system assumes it to be the complete library name.
