Intermittant error generating Excel from SQL statement

I wonder if the owner of the data source was not matching the job... Regardless, I will email you an updated version of the VVBATCH program with some extra logging that will document exactly why it thinks the data queues it's deleting are orphaned.

Hi Rob,
The user ran the SQL to Excel job again today at 14:49.40 and the submitted job was called:
453000/LINGIERM/VALENCE6P
At 14:49.42 it deleted:
VV452991I in VALENCE6P
VV452991O in VALENCE6P
and created VV453000I type *DTAQ in VALENCE6P
Then at 14:53:46 (4 mins later) the job crashed because VV453000I *DTAQ was missing.
I ran the process again exactly the same as LINGIERM at 16:05 after the warehouse had closed and it all worked perfectly.
The resultant spreadsheet is just over 30MB and contains 673,200 rows. Megan needs this detail for her forecast analysis.
It looks like changing the submitted job name didn't fix the problem.
The previous excel job lmust have eft behind the other DTAQ's that this job cleaned up.
Sorry.

Hi Rob,
I changed this particular job to submit the excel generation batch job as "VALENCE6P". It ran successfully but finished the main excel piece in 66 secs because it's Saturday. The failed job took nearly 4 minutes to run the excel piece as per the job log. In a lightly loaded system the process works but during a normal workload the timing seems to be fail the process. I can't name every excel job VALENCE6P (we run quite a few reports into excel) and our test environment runs over VALENCE6D in the library list. Maybe cleanup can run later or wait longer than 4 minutes before deciding something is orphaned?
Thanks for the response.
Peter

Hi Peter,
I suspect the cleanup routine is deleting those data queues because it thinks they're orphaned -- meaning the job using it for communication is no longer running.
Data queues for VVBATCH are assumed to be running in Valence, thus data queues VV444890I and VV444890O would be assumed to be running under a job named VALENCE6P, with a job number of 444890, and a user ID matching the creator of the data queue (typically QTMHHTTP).
If you're running the VVBATCH program outside of Valence, you probably need to give it a job name that matches Valence instance library you're using (VALENCE6P). So try that and see if the problem goes away.
Assuming switching your batch job name to VALENCE6P does indeed resolve the issue, perhaps we can adjust the logic in a future build to pull the job name from the text description associated with the data queue objects, instead of assuming it matches the Valence instance library. The data queues created by this process currently have a blank description, but that can be changed.

Intermittant error generating Excel from SQL statement
Hi Support,
We have a process that generates excel using statement:
vvOut_execSQLtoSS
Sometimes this works but often it fails. When it fails we repeat exactly the same and it may work or fail again. Eventually, it works. Each time, it's in a separate submitted job to ensure no legacy issues within the job or memory leaks.
The job log shows that a *DTAQ is created (my example is VV444809I) but is deleted before it needs to be used. I think there is a timing issue because this is a large spreadsheet. See relevant joblog segment:
