flags (onstat -g ses)
John: So, the smoking gun may be the "PDQ is set to 10%". That may cause sessions to go into a wait state that is not documented by any flags in onstat. The onstat -g mgm report will tell the tale. Here's the thing to remember about PDQ. It controls the percentage of PDQ resource…

SHARED MEMORY ALLOCATION

Hoping to get some opinions on this. We have a public website that is currently using our main production database (IDS 11.50.FC6). The main query used by the website uses a single table that typically has 50K to 100K rows. The query typically completes in 0.4 to 0.5 seconds. …

Use of fragmentaion for tables
