Looks like OPNQRYF is not threadsafe, so you should not be using that
command in a threaded environment.
You can see which commands are threadsafe by doing DSPCMD and looking at the
Threadsafe keyword.
Threadsafe keyword is defined as *COND for OVRDBF, which means conditional.

I recommend you go to the following site:

http://publib.boulder.ibm.com/iseries/v5r2/ic2924/info/rbam6/rbam6clfinder.h
tm

and type the commands you are using and once you find them, search on
"thread".  You'll see if they're threadsafe and under what conditions.
For example, for OVRDBF there are these restrictions:

Restrictions:

1. In a multithreaded job, this command may only be issued from the initial
thread. 
2. In a multithreaded job, only overrides scoped to the job or an ILE
activation group will affect opens performed in a secondary thread.

 Subject: [C400-L] FILTER ON FILE

HI.
 
I did some simple C programs that use OVRDBF and OPNQRYF to do a Filter
at a PF.
Now I'm trying to do the same but in a multithreaded environment. 
My problem is OVRDBF don't work at that environment, how can I use
OPNQRYF without OVRDBF ?
 
Thanks.
