Improving System/21 Performance




If you have not analyzed access path creation in System/21 using STRDBMON,
your system probably runs far slower that it should.  We substantially
reduced our month end processing time without changing a single program.
Some on demand and daily reports that used to take minutes to run now take
seconds.  Using STRDBMON, we were able to identify temporary access paths
created by SQL, OPNQRYF, and Query/400 that either took forever to create
or were created frequently.  All we had to do was create logical paths
using the suggested key structure.

If anyone is interested, I have a short 9 page PowerPoint presentation that
describes the technique in more detail.

Thanks.
