Good morning.
When trying to move our Windows V5 ConfigMgr to an AIX V6 ConfigMgr. When issuing the mqsicreateconfigmgr command it runs for about 1 minute then comes back with a Java heap error. I know with the V5 you could use the -j to increase the size, but the V6 does not have that same option. Has anyone ran into this problem? Thank you for any advice you can give me. |

Here is the command I am running:
mqsicreateconfigmgr WBIBCMT1 -i wmbcmdev -a XXXXXX -q WBIBCMT1 -n //kct-mqconfig3:50000/DMQSCMDB -u wmqi -p XXXXXXX |

Maybe you should mqsimigrate it instead of mqsicreateing it.

| I thought about doing the mqsimigrate, but while testing in our sandbox envirornment, we did all of our testing with the mqsicreate. With our upper management, there would require the entire project to start over and I was trying to avoid that. I will look into that this morning. |

I guess you'll have to look at system logs and etc. a bit more, then.

with the version 5 there was a -j option to allow you to set the Java heap size. That option is not available with the version 6 mqsicreateconfigmgr. I have a PMR opened with IBM, but they are moving really slow on this. I was hoping someone had ran into this problem and had figured out how to get the Java heap size adjusted.
Thank you for your help though. |

Well, maybe someone who's done this more will pipe up. Or someone who knows the code.

I had a problem with the mqsicreateconfigmgr hanging (on linux) and got around it with: export JAVA_COMPILER=none ... I'm not saying it will help, but it doesn't hurt to try...

| That did not work. It took a lot longer to die, but it still got the same error. |

This is the error I am getting. I have contacted IBM, but they are moving really slow on this.

I have received a fix from IBM and I am testing it now. I justed wanted to let you know what IBM sent back. The max java heap size was set to 64MB and could not be changed. They have made a change on their side. Here is what IBM sent back to me. I just wanted to pass along the information.
*******************
Hi, the max heap size for the mqsicreateconfigmgr command is fixed at
64MB. I have built a test fix for the libImbCmdLib.a library that should
allow the customer to override this by setting the environment variable
MQSI_JAVACMD_MAXHEAPSIZE=<new_heap_size_in_bytes>
This needs to be set in bytes, so I would suggest to initially set this
to something close to 128MB,
eg. export MQSI_JAVACMD_MAXHEAPSIZE=134000000
If that's not sufficient, double it again.
If this is the cause of the problem, then we will obviously need to take
an APAR.
The test fix. |

| That worked just fine. So I was able to get the configMgr migrated from V5 on Windows to a V6 on AIX. We have two brokers running with 47 execution groups and 350 flows and it only took about 25 minutes. Just an FYI. |
