Persistant Cache Question

[elvenmaiden]

Would like to implement persistant-named cache on concurrent sessions in Informatica 7. The question I have is if the recache is set on one of 7 sessions in a concurrent batch will the other concurrent sessions wait for the recache to occur?

Also, if the look-up using persistant cache and recache occurs as the 7th lookup in a mapping, while the other mappings it occurs as the 4th or 5th lookup...will the other mappings wait for the recache or will they process on 'stale' cache?

There is a separate INformatica forum - perhaps you would get better results by posting there:

This is an interesting scenario, since all sessions would be working off one named persistent cache. I have not seen a document that covers this from informatica. We use named persistent cache but do not have the need to recache during the process. I would suggest trying it out with 2 or 3 sessions. If you do please post the results.

not sure that helps ?
