Having set up an administrative subscription it is not working properly. But when I try on another QM the same commands work properly.
The commands are:
| Code: |
DEFINE TOPIC(ZPAT.DUP) TOPICSTR('/zpat/test') DURSUB(YES) REPLACE
DEFINE QALIAS(ZPAT.ALIAS) DEFPSIST(YES) TARGTYPE(TOPIC) TARGET(ZPAT.DUP) REPLACE
DEFINE QLOCAL(ZPAT.QUEUE1) DEFPSIST(YES) REPLACE
DELETE SUB(ZPAT.SUB1)
DEFINE SUB(ZPAT.SUB1) DEST(ZPAT.QUEUE1) TOPICOBJ(ZPAT.DUP) DESTQMGR(XXXXXX) DESTCLAS(PROVIDED) EXPIRY(UNLIMITED) REQONLY(NO) PSPROP(NONE)
|
This is the display of the sub on QM 1

The topic string in the sub is different even though the exact same command file was run. The first example does not work, the second one does (when a PUT is done to the alias queue).
Any ideas - both QMs are on the same box (WMQ 7.0.1.3, AIX)? QM 1 has added an unwanted and uncommanded trailing slash to the topic string in the sub. Other QMs don't do this and I can't see why this would be. |

just a quick guess without making much sense ... ... psmode settings are the same for both qmgrs?

PSMODE on both = enabled. I can't see any system set up differences.

OK using this format of the command is a workaround - although it should be not be necessary to specify both a topic object and a topic string on a define sub.
DEFINE SUB(ZPAT.SUB1) DEST(ZPAT.QUEUE1) TOPICOBJ(ZPAT.DUP) TOPICSTR('#') PSPROP(NONE)
I would guess the problem is that the define sub command tried to concatenate something after the topic string from the topic object, even when it should not have. Why this behaviour varies between two QMs - I do not know. |

Right, I have found the reason. For some reason we had lost the SYSTEM.DEFAULT.SUB subscription. I re-created it using the backup MQSC definitions from another queue manager. This was last week.
Guess what - the MS03 backup would appear to have a bug in that a null TOPICSTR value is saved as TOPICSTR(' ') with one blank, instead of TOPICSTR('').
This blank character is therefore added to all new subscriptions that specify only a topic object and a delimiter of / is automatically inserted.
Over to the MS03 maintainer..... |

This is a bug in the earlier releases of MS03 that supported v7 subscriptions.
It should be resolved in the currently available builds (that report as v 6.1.3.1).
If it is not, please contact me by the email in the read.me. |
