After Migrating to V8.1 Issue with Sort Stage

Posted: Wed Oct 13, 2010 1:00 am
by Vidyut
We just migrated our development environment to V8.1 from 7.5.2.
Have done all the configuration known to me.
We have one Datastage Server(04) and one Database Server(05)
Everything is running fine except the SORT Stage.
Sort is running fine if i change Sort Utility from datastage to Unix.

We are getting error on Node4 that belongs to the Database Server.

#### STAGE: Sort_31
## Operator
tsort
## Operator options

I would start with your ulimit settings at both the user and the system limits level, see
...Need to be able to open at least 16 files; please check your ulimit setting for number of file descriptors...

have set all the parameters in ulimit file as unlimited for root as well as dsadm user in both the servers i.e.datastage and database
The problem still exists....
Thanks

Edit your job and add a before-job subroutine call to "ExecSH" with the parameter "ulimit -a" and see what the actual runtime value is. I am willing to be that the value you get is "16" and not unlimited.

Note that you ulimit value is often set or modified in the dsenv file.
