Sessions fail when run in parallel

[sahilk1975]

Hello all,

I am tring to run concurrent sessions in my workflow, as soon as I start the workflow, apart from first session, all the sessions fail. They do not even initialize, hence no log files are generated.

Those same sessions when run in series, they run successfully. Also, on the same server, in other folder, we are able to run sessions in parallel. Its only in this folder, we are facing this issue. We are using 6.2 version of Infa.

We really don't know what is going wrong.
Please help us

Thanks
Umesh

What does the workflow log say?
Did you check for deadlocks?
Does the number of parallel sessions exceed the number of allowed by you server setting? The default for Maxsessions in server config is 10.

Also check LMSharedMem..

==========================================

s_Dim_Line_Of_Business failed whicle s_Dim_Job_Title succeeded. Both were started in parallel.

Yes, max sessions are 10 and no other jobs are running on server.

shared memory is
LMSharedMem=2000000

Possibly its a deadlock, could you please tell me how to figure it out.

Thanks

Hi Ties ,

The issue is resolved now after restarting infa server and repository server.

Thanks for all your help.

Allright, that points to a cache problem. What is your setup, version 6 has known issues with - for example - DB2.
