| I have MQ7 on Windows but get command not found when entering strmqmbrk - don't know what to do to fix this. Also, I'm wondering how the MQMBRK persists subscriptions - file system, database? |

Pub Sub changed significantly under to covers between MQ 6 and MQ 7. That command only applies to the i5/OS in MQ 7.0.
Take a look at the Pub Sub guide on the Version 7 MQ Info Center for more info.

Peter,
I'm reading the guide and see that I can display stored subscriptions using the DIS SBSTATUS command. However, when I try this I get not recognized internal or external command.
the pub sub guide states:
The local queue manager stores subscription information and when it receives a publication, scans the information to determine whether there is a subscription that matches the publication's topic and selection string.
But the guide does not specify where the subscriptions are stored or if there is a limitation on # of subscriptions? |

Please make sure you are reviewing the WebSphere MQ Version 7 Guide.
And then try "dis sub(*)". |

Jeff,
I am definitely looking at MQ Version 7.0 Publish/Subscribe User's Guide -
dspmq command works fine, but none of the pub/sub commands are found internal or external.
I also want to know how MQ persists subscriptions and if there is a limit to the number of subscriptions (this info does not appear in the documentation). |

Subscriptions are persisted as MQSC SUBSCRIPTION objects, that you can view using "DIS SUB(*) all".
I forget if this shows you dynamic subscriptions to dynamic topics or not, but I believe it does. It's certainly a source of some ... well, it has enabled me to rethink some portions of saveqmgr, let's just say.
The old MQ v6 pub/sub commands aren't relevant any more.

Jeff,
curioser and curioser. when logged in as mqm and trying any of
dis sub(*) all
dis sub (*) all
dis sub(*)
dis sub (*)
I receive this error:
-bash: syntax error near unexpected token '('
this is on a 64 bit x-series Linux (red hat) system running MQ 7.0. The server is running ESX and the Linux is virtual. |
