Elongated response times observed in development server

SA-9826

Summary



The development server experiences extremely poor response times (minutes to try to open rules, save rules, and other such actions).

Error Messages



Not Applicable

Steps to Reproduce



Open, save and checkin the rule to observe the issue.

Root Cause



The slowness is a result of poor usage of indexes for table pr_sys_appcache_shortcut by Oracle. This is a known issue with Oracle when index uniqueness goes beyond 32 characters.

Resolution



Below is a link to a PDN article describing the root of the problem where Oracle ignores the index due to its apparent non-uniqueness.
