Issue: Performance is degraded because of a large number of external users or groups available in Shared Services.
Solutions:
Set up a filter to retrieve only the required users.
Oracle recommends that you set the group URL and tune the group filter to decrease the number of groups that Shared Services must parse to build the cache. Doing so improves runtime performance significantly.
See Faster User Retrieval, Application Registration, and Security Loadingand Maximum Size Setting for User / Group Searches.
Issue: Shared Services accesses LDAP and MSAD group information even though you do not use LDAP or MSAD groups.
Solution: Create groups in Native Directory and assign users from LDAP and MSAD directories to them, then set the “use groups” option to false.
Use the Shared Services Console to modify the user directory configuration. Verify that the Support Groups check box on the Group Configuration tab is clear.
