I encountered a strange problem when reading user trace. It seems that the mqsireadlog-command hangs and I can’t figure out the reason.

The flow is designed with the following nodes: MQInput -> Compute -> Trace {$Root} -> RCD -> Trace {$Root} -> FileOutput

In Compute node I’m executing select statement which retrieves XML data from Oracle. After that the retrieved data is passed to the RCD as blob. In RCD I’m using XMLNSC as message domain. FileOutput node then writes the XML data to the directory and everything seems to be in order.

And now comes the tricky part. After the file has been written to the directory I run the mqsireadlog-command. Everything goes smooth when the size of XML data stored in DB is about 10KB. When the size of the XML data stored in the DB is for example 60KB the mqsireadlog-command hangs. I have also modified the flow so that it contains only these nodes: MQInput -> Compute -> Trace. The same mqsireadlog hang occurs here too when reading bigger chunk of data from the DB. I have also tried to stop the flow before executing the mqsireadlog but it doesn’t help.

I’m using the following script:

Code:

-mqsireadlog BK_SD001T -u -e XMLTest -o rtvTrace.out
-mqsiformatlog -i rtvTrace.out -o rtvTrace.log
-mqsichangetrace BK_SD001T -u -e XMLTest -r -l debug -c 2000000

Hmmm

I normally do the following

1) mqsichangetrace .... -l debug
2) send the message
3) mqsichangetrace ... -l none
4) mqsireadlog ....
5) mqsiformatlog ....

The other thing is that you could try reducing the size of the -c param. Ive never needed more than 65536.

Yeah I have tried that too but it didn't help. I have also reduced the size of the -c param but that didn't help either.

I think the problem is related to this --> http://www-01.ibm.com/support/docview.wss?rs=849&context=SSKM8N&context=SS3GH2&context=SSKMAB&dc=DB550&uid=swg1PM00780&loc=en_US&cs=utf-8&lang=en

Well, I'm still stuck and I would appreciate if anyone have any suggestions for the problem
