Re: Index Selection -- MIDRANGE-L

× 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.

1) Use visual explain and not debug - the debug info component has not been updated in some time and is no longer considered a valid resource for performance info.

2) You didn't say if the data is the same on both machines. If different this could very well be valid behaviour based on the initial probes. Visual Explain would show you this.

Ok...two systems, both on 7.1. Execute STRDBG UPDPROD(*YES). Run a program
on system A. Job log shows an index was used for bit map processing. Run
the same program on system B. Same index in place (though different
libraries). System B job log says arrival sequence was used. How can I
figure out why the index is used on one system and not the other? Thanks!
