Informix upgrade from 10.00 to 11.50
A user planning an Informix upgrade from 10.00 to 11.50 on AIX 5.3 asked about risks beyond those in the migration guide/machine notes, especially performance regressions. The only issue reported was that a small number of queries may pick different query plans after the upgrade. A follow-up question about compiler/SDK dependencies was answered: CSDK 3.50 is recommended to support the new features, available from the free trial download pages. No deeper problems or detailed troubleshooting were discussed.

Hi guys We are about to do an informix version upgrade from 10.00 to 11.50 on AIX 5.3. I would just like to know if there are any major/minor risks that we should take note of, other than those mentioned in the Informix migration guide/machine notes? Have any of you experiance any major performance problems after an upgrade? If so what were these problems? Thanks in advance :) Regards Tien Cheng

Thanks in advance :) There is always a chance that a small number of queries may choose a different query plan. This is about the only problem I've seen. -- Cheers, Obnoxio The Clown http://obotheclown.blogspot.com I will now proceed to pleasure myself with this fish. -- This message has been scanned for viruses and dangerous content by OpenProtect(http://www.openprotect.com), and is believed to be clean.
