All queue managers

 

Use the General and Extended WebSphere MQ properties page from the WebSphere MQ Explorer, or the AllQueueManagers stanza in the mqs.ini file to specify the following information about all queue managers.

DefaultPrefix=directory_name

This attribute specifies the path to the qmgrs directory, within which the queue manager data is kept.

If you change the default prefix for the queue manager, replicate the directory structure that was created at installation time (see Figure 1).

In particular, create the qmgrs structure. Stop WebSphere MQ before changing the default prefix, and restart WebSphere MQ only after you have moved the structures to the new location and changed the default prefix.

Do not delete the /var/mqm/errors directory on UNIX systems, or the \errors directory on Windows systems.

As an alternative to changing the default prefix, we can use the environment variable MQSPREFIX to override the DefaultPrefix for the crtmqm command.

Because of operating system restrictions, keep the supplied path sufficiently short so that the sum of the path length and any queue manager name is a maximum of 70 characters long.

ConvEBCDICNewline=NL_TO_LF|TABLE|ISO

EBCDIC code pages contain a new line (NL) character that is not supported by ASCII code pages (although some ISO variants of ASCII contain an equivalent).

Use the ConvEBCDICNewline attribute to specify how WebSphere MQ is to convert the EBCDIC NL character into ASCII format.

NL_TO_LF

Convert the EBCDIC NL character (X'15') to the ASCII line feed character, LF (X'0A'), for all EBCDIC to ASCII conversions.

NL_TO_LF is the default.

TABLE

Convert the EBCDIC NL character according to the conversion tables used on your platform for all EBCDIC to ASCII conversions.

The effect of this type of conversion might vary from platform to platform and from language to language; even on the same platform, the behavior might vary if you use different CCSIDs.

ISO

Convert:

  • ISO CCSIDs using the TABLE method

  • All other CCSIDs using the NL_TO_CF method

Possible ISO CCSIDs are shown in Table 1.

List of possible ISO CCSIDs
CCSID Code Set
819 ISO8859-1
912 ISO8859-2
915 ISO8859-5
1089 ISO8859-6
813 ISO8859-7
916 ISO8859-8
920 ISO8859-9
1051 roman8

If the ASCII CCSID is not an ISO subset, ConvEBCDICNewline defaults to NL_TO_LF.

For more information about data conversion, see the WebSphere MQ Application Programming Guide.
