The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
You'd need to compare access plans for two executions. You can do that
using Visual Explain. For STRSQL session, collect dbmon data and then bring
it up in VE. Do the same for iNav (much easier to bring up VE).
Perhaps it's CQE vs SQE? Or *ALLIO vs *FIRSTIO? Or ALWCPYDTA setting
differs?
As you know query optimizer considers a great number of environmental
factors when building an access plan.

Subject: SQL scripts in iNav
Hi
I'm running a select with group by, order by clauses. If I execute it on a
greenscreen, it takes a few seconds and I see the message that an index is
being created during the request. Each time. But with iNav, the subsequent
executions are almost instantaneous. What's occurring?
Thanks
