The AllQueueManagers stanza

The AllQueueManagers stanza can specify:

DefaultPrefix=directory_name
The path to the qmgrs directory, below which the queue manager data is kept.

If you change the default prefix for the queue manager, you must replicate the directory structure that was created at installation time.

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

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

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 the method WebSphere MQ is to use when converting 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 OS/400(R) for all EBCDIC to ASCII conversions.

Note that the effect of this type of conversion can vary from language to language .

ISO
Specify ISO if you want:
  • ISO CCSIDs to be converted using the TABLE method
  • All other CCSIDs to be converted using the NL_TO_CF method.

Possible ISO CCSIDs are shown in Table 12.

Table 12. 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.
