Ok, sorry: that was an exercise in RTFM... I know understand why there are 3 separate db pools (main, subquery and log) defined in ACS: onces I've done ns_db gethandle on a database all my requests will go through it. If I then try to use the same connection for a different query, I get error. My question is, though: why can I not get a new handle on the same db? Related: if I do ns_db gethandle $pool_name 2, will I be able to do independent getrows?
