What do you think?
Have you tried different cases? What was the result?
Wouldn't that be just as quick as posting your question here?

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

You shouldn't be creating any new topic under $SYS.

Ok, you can't create a new topic with a publication that has a wildcard in it's name. If you're talking about subscribing to a topic, then case sensitivity would have nothing to do with wildcards or not (as wildcards are case insensitive.
And given that IIB uses the underlying queue manager for all it's publish / subscribe the issue of case sensitivity should be obvious.

to make it clear - i have created a topic with topic String
Topic = TEST_BROKER
TOPIC_STR = $SYS/Broker/+/Monitoring/+/#
CLROUTE = TOPICHOST
PUBSCOPE = ALL
SUBSCOPE = ALL
CLUSTER = TESTCLS01X
if i dont use the wild card, i can test it between the queue managers, if there is any wild card its not coming on different queue managers. (using amqspub and amqsub)

There's a difference between an MQ Topic Object and an MQ pub/sub topic itself.
Topic Objects are used to provide shortcuts/pointers to parts of the topic tree. Subscriptions can then use the topic object to allow them to be relocatable without altering the code.
So if you want to create a subscription to the topic string "$SYS/Broker/+/Monitoring/+/#", you can create a topic object that points to "$SYS/Broker/", and then specify that in your subscription, with the additional piece of "+/Monitoring/+/#". Or something like that.
This has nothing to do with if a subscription to "/A/B/C" will receive messages published to "/a/b/c". |

I hope it's not the same thing that you showed, using wild cards in the topic string of a TOPIC object. Because as far as I know, that shouldn't work.
Again, TOPIC objects point to parts of the topic tree - specific parts, not generic parts - and are used to provide shortcuts for applications and points of authentication. |

True, you are right , it's related to Pub/Sub,
