Hi
I'm trying to setup a standby server for my current prod server which has 15 QM's in it. AIX 5.3 and MQ 5.3
Do I need to re-create all the QM's again or I can import the dump from the prod server to the standby after MQ installation. |

Well, first you should upgrade your production server to v7.
Second, you should review the documentation on Backup and Recovery.
Third you should review your requirements for the standby server. Do you need to move MESSAGES over? or just configuration? Do you need to worry about how long it takes before the standby server is running? Do you need to provide uptime for applications in the event of a failure on production?
Then you can formulate a plan, and go back to the documentation and decide which of the various options actually suits your needs. |

Hi itsme_001,
I hope you meant a DR else it's surprising that you don't already have a standby since the day you went live, coz the standby license would not have been priced...
Anyway, if you mean that you want a passive box which will get activated on failover, then you are looking for an active-passive configuration. But in such cases the installed components are usually on a SAN storage, which will enable the passive server to have the same QM's and messages (same state) as the failed server.
Regards. |

| Use support pac MS03 or MO71 (export) to generate MQSC commands to re-create existing QM objects. |

You do not need to use MS03.
See the topic Using a backup queue manager in the WMQ System Admin manual. You will need to upgrade to v6 to use this feature.

The need for a standby is to replace the one in production; since we need to do some hardware changes in the current setup and rather than doing the changes we are opting to setup a completely new one with the required hardware configuration.
I did try using the MS03 pac, but its not working; might be it may not support for my version.
currently going thru the backup and recovery docs. |

Then it is not a standby, it's replacement infrastructure. Build it, connect it, test it etc., and cut over to it.

As I'm sure mqjeff will himself assure you, it is backwardly compatible, however, as you have not stated platform, are you sure you are using the correct version?

Also, by default the code generated is for the same version.
V7 works a little bit differently especially where Alias queues are concerned. Make sure you specify the version you want the output in...

There is a note in the read.me on the -v flag and the fact that it's almost certainly unnecessary in most cases.
If you are actually having specific problems with MS03, then please contact me by email, at the address in the read.me file.
If by "doesn't work", you mean "complains about a magic number", then you are trying to run a 64bit executeable on a 32bit platform. Recompile a 32bit version, or again, contact me by email at the address in the read.me. |
