Environment:

3-tier
Custom Java Client on WAS
Workflow Server 3.4.3 on AIX 5.1
DB2 7.2 on AIX
& MQ 5.3

A java listener on AIX listens to the client requests and gets data from DB2.

The DB2 box was rebooted for some reason and then on the Execution servers starts terminating upon receiving a request.

I have also tried from the FAT client and i was able to see only Process Instance List and template list.
Could not see Workitems or Worklists. It was hanging at that point.


Any ideas???

After your Db2 server was rebooted did you restart WF ?

I would say that this is your problem

Why this is happening I do not know. You probably need to open a PMR

Yes it is strange.

We deleted the worklists from the table and we could logon thru the Fat & Web client.

We r in the process of login thru the custom java client

So, are you doing direct access to the DB2 Worklist Table? Or are you saying that MQWF is corrupting the Worklist on its own?

And IBM said that the public worklists were corrupted

Was there an explanation as to why/how these workflow worklists got corrupted from IBM? Were they able to recreate this. It would be interesting to know whether or not this was more of a one time thing or is this something that can happen again.

Thanks,
