Re: Problem with multiple simultaneous searches

Joe, I think WDSC uses the EVFEVENT file in the *CURLIB of the connection.

Then again, I have also had this error even though I was the only WDSC 
user on the system (since the last IPL).

Subject
[WDSCI-L] Problem with multiple simultaneous searches






I was just giving an onsite class on WDSC to a group of nine RPG 
programmers
and while they were generally pretty enthusiastic about the tool, we did 
hit
one really nasty snag.

At one point, I had the entire class do an iSeries Search.  At that point,
odd things happened.  Some people got other people's results, and some
people got the following error:

"EVFF9007E: Cannot remove and create member EVFEVENT in file QGPL/EVFEVENT
to hold the search result.  Release the file and try again."

Hmm.  It seems like all search requests hit the same member.  They should 
at
the very least be different members for different connections (you could 
use
the job number of the connection job as the differentiator).  There are
issues with cleaning up those members when the jobs end, but there are 
ways
to handle that (e.g., you can register a cancel handler for the connection
job).

Anything is better than everybody sharing the same member.

In our class, we had people searching two source members in their own
library for a string; some people got results from other libraries, and 
some
didn't get anything at all or got the halt mentioned above.
