If your opensso instance uses a remote config store, you can improve the performance using the alternative in-memory notification for Config Store.
If this property com.sun.identity.sm.enableDataStoreNotification=true
then Opensso makes use of a persistent ldap connection to listen to the event notifications.
Disabling Datastore notification
-------------------------
Step 1) Go the page
Configuration -> Servers & Sites -> Server Instancce -> SDK
Set
com.sun.identity.sm.enableDataStoreNotification=false
com.sun.am.event.connection.disable.list=aci,um,sm
Step 2) Restart the container
Step 3) Check the sun one directory server logs/opensso debug logs.(Assuming that the debug level is set to message)
Sample messages are pasted below
1) This is from DS access logs
No psearch after disabling the datastore notification
