Z/OS CCSID 500 or CCSID 819

Discussion:

Dear Listers

We are engaged in attempting to develop MQ(Z/OS 5.3.1) & Java and are
experiencing a problem where we believe the code page setting for the Queue
Manager is not right.
This is a bit of trial & error at the moment but we think the setting should
be set to 819 instead of 500, which is the current definition for
the QMGR
Can we change the current Queue Manager, or do we need to create a new QMGR,
we have defined quite a few queues to the existing Manager, so would prefer
not to lose them if it needs to be deleted/re-defined to update its code
page setting.

Questions;

1....Is the default under Z/OS CCSID 500 or CCSID 819
2....Can the CCSID be altered in the current QMGR without adverse affect and
if so is this done in the ZPARMS?

Thank you in advance for any assistance

This is set in the CSQ6SYSP MACRO when you are generating your MQ ZPARM. The default is 0 (zero) which says to use the default for the system....in the case of z/OS this is 500.

What problems are you having? I have a lot of java/MQ running, native in USS, and also through WebSphere 4.01 as well as 5.x. Explain the problems with Java and maybe I can be of further assistance.

Stewart,

CCSID 500 is the default for z/OS mainframes (EBCDIC, english) whereas CCSID 819 is the default for Unix-Systems (ASCII, englisch). You cannot set 819 for z/OS because you do not have ASCII. On Unix you may change the CCSID using an ALTER QMGR command, but you may get trouble, when the new value is not supported on your system.

Why do you want to change your CCSID? When you have connections between z/OS and Unix the two different CCSIDs are needed, to convert messages sent from z/OS to Unix and back.

Regards
Hubert

To add to this, I believe in the US the other CCSID you can use is 37. This
is what most installations I have been at usually change their CCSID to.
There are less characters in 37 that are mutilated in the conversion to
Windows/UNIX.

Basically the QMGR takes the incoming CCSID, base CCSID, converts them to
hex and concats the numbers and goes looking for the conversion table that
was installed at MQ installation time. (except AIX which uses the OS
installed tables). It then uses the hex weight value to look up in the
conversion table as a displacement to get the character it is suppose to
convert to. Boom...you have conversion!!! Magical!!! Now they need to get
the tables right!!!
