Hi, is it possible to retrieve the query plan(s) for an already running SQL (or for SQLs from the session cache)? The problem: When I run the 'slow' SQL (with set explain) it runs fast and well optimized - but the application runs the same SQL much slower.

onstat -u to find out what running sqls and the session number. onstat -g ses {number} to get the current and possibly previous SQL. Assuming IDS 10 you can turn explain on with onmode -Y {session} 1 You can also get this information from sysmaster.
