SAVSAVFDTA (Save Save File Data)

SAVSAVFDTA Command syntax diagram

 

Purpose

The Save Save File Data (SAVSAVFDTA) command saves the contents of a save file to tape, optical, or diskette media. This command saves the save data in the save file to the device in a way that allows the user to restore objects directly from the device.

A save file containing data created by the Save Security Data (SAVSECDTA) or Save Configuration (SAVCFG) command can only be saved to tape or optical. A save file containing data created by the Save Licensed Program (SAVLICPGM) command cannot be saved by this command.

The information written on media by this command is similar to the data that was previously written to the save file by the save command that originally created the save file data. This includes the object descriptions, and object contents that existed when the original save operation was done.

This command uses only the save file and device description objects; it does not refer to or modify the description or contents of the objects included in the file save data. Thus, objects included in the save file are not locked during the running of this command, and the save history information (date, place, and time when each object was last saved) is not updated by this command for each object in the save file.

The description of the save file is not included in the save operation (unless it was included with the objects that were saved to create the save data in the file). In addition, this command does not update the save history information for the save file object, so the last save operation date, time, and place always identify the last save operation of the save file object description, not its contents.

Note: This command ignores all file overrides currently in effect for the job, except for the output file.

 

Restrictions

  1. The user of this command must have use authority for the save file and use authority for the tape, optical, or diskette device description.

  2. All diskettes to be used to perform the save operation must be initialized in the save/restore format. If a tape is used, it must have a standard label. Also, the save file cannot be in use by a job running at the time the save operation occurs.

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

 

Required Parameters

SAVF
Specifies the qualified name of the save file whose contents are saved. If no library qualifier is specified, *LIBL is used to find the file.

Note: The save file must contain the data made by the run of a previous save command or an error message is sent, and its contents are not saved to diskette or tape.

The name of the save file can be qualified by one of the following library values:

*LIBL: All libraries in the job's library list are searched until the first match is found.

*CURLIB: The current library for the job is searched. If no library is specified as the current library for the job, the QGPL library is used.

library-name: Specify the name of the library to be searched.

save-file-name: Specify the name of the save file.

DEV
Specifies the names of the devices used for the save operation. Each device name must already be known on the system by a device description.

diskette-device-name: Specify the name of the diskette device used to save the data.

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 to save the data.

tape-device-name: Specify the name of one or more tape devices that are used for the save operation. If more than one tape device is used, specify the names of the devices in the order they are used. Up to four device names can be specified. When more than one tape volume is used, it may be advantageous to use more than one tape device so that tape volumes can be rewound and/or unloaded while another tape device is being processed.

 

Optional Parameters

VOL
Specifies the volume identifiers of the volumes, or the cartridge identifier of a tape in a tape media library device, on which the data is saved. The volumes must be placed in the device in the order specified on this parameter. More information on this parameter is in Commonly used parameters.

*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.

volume-identifier: Specify the identifiers of one or more volumes in the order they are placed in the device and used to perform the save operation.

SEQNBR
Specifies, when tape is used, the sequence number on the tape where the save operation begins.

*END: The system saves the data starting after the last sequence number on the first tape. If the first tape is full, an error message is issued and the operation ends.

sequence-number: Specify the sequence number of the file. Valid values range from 1 through 16777215.

ENDOPT
Specifies the operation that is automatically performed 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.

Note: This parameter is valid only if a tape or optical device name is specified on 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.

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. Clearing active data removes all files from the volume, starting at the specified sequence number for tape. Replacing active data on optical media replaces only the optical files created by this operation.

 

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 on the NEWVOL parameter.

  2. Clearing an optical volume does initialize it.

  3. Clearing a diskette does not initialize it. You should initialize diskettes to a save and restore format before the save command is issued by using the Initialize Diskette (INZDKT) command and specifying FMT(*SAVRST).

  4. 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, diskette, or 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 on 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 or diskette, 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.

*REPLACE: Active data on the media is automatically replaced. Optical volumes are not initialized. Tapes, diskettes, and save files are automatically cleared in the same way as the *ALL value.

EXPDATE
Specifies the expiration date. The files cannot be overwritten until the expiration date. The expiration date must be later than or equal to the current date.

PERM: The file written on diskette or tape is protected permanently.

expiration-date: Specify the date on which protection of the file on diskette or tape ends. The date must be specified in job date format.

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 on the DEV parameter support the compaction feature.

*NO: Device data compaction is not performed.

OUTPUT
Specifies whether a list with information about the saved contents of a save file is created. The information can be printed with the job's spooled output or directed to a database file.

*NONE: No output listing is created.

*PRINT: The output is printed with the job's spooled output.

*OUTFILE: The output is directed to the database file specified on the OUTFILE parameter.

Note: If OUTPUT(*OUTFILE) is specified, specify the database file name on the OUTFILE parameter.

OUTFILE
Specifies the qualified name of the database file to which the information about the object is directed when *OUTFILE is specified on the OUTPUT parameter. If the file does not exist, this command creates a database file in the specified library. If a new file is created, the system uses QASAVOBJ in QSYS with the format name QSRSAV as a model.

The name of the database file can be qualified by one of the following library values:

*LIBL: All libraries in the job's library list are searched until the first match is found.

*CURLIB: The current library for the job is searched. If no library is specified as the current library for the job, the QGPL library is used.

library-name: Specify the name of the library to be searched.

database-file-name: Specify the name of the database file to which the output of the command is directed.

OUTMBR
Specifies the name of the database file member to which the output is directed when OUTPUT(*OUTFILE) is specified.

Element 1: Member to Receive Output

*FIRST: The first member in the file receives the output. If OUTMBR(*FIRST) is specified and the member does not exist, the system creates a member with the name of the file specified on the OUTFILE parameter.

member-name: Specify the name of the file member that receives the output. If OUTMBR(member-name) is specified and the member does not exist, the system creates it. If the member exists, the user can add records to the end of the existing member or clear the existing member and add the records.

Element 2: Operation to Perform on Member

*REPLACE: The existing records in the specified database file member are replaced by the new records.

*ADD: The new records are added to the existing information in the specified database file member.

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 path names.

'*': 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.

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

*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.

If the target release value that is specified is earlier than V3R7M0 then the block size supported by all device types is used.

*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.

Examples for SAVSAVFDTA

Example 1: Clearing All Diskettes and Tapes Encountered 

SAVSAVFDTA  SAVF(ONLINE)  DEV(TAP01)
  SEQNBR(1)  CLEAR(*ALL)

This command saves the contents of save file ONLINE to the first file on the tape volume on device TAP01. Files that have not ended on either the first tape volume or on subsequent volumes are overwritten without an inquiry message because CLEAR(*ALL) is specified.

Example 2: Restoring Library from Tape

If, in the last save command to save library USRLIB, the save file was: 

SAVLIB  USRLIB  SAVF(ONLINE)

Then the following command must be specified to restore the library from tape: 

RSTLIB  USRLIB DEV(TAP01)  VOL(*MOUNTED)
