- PseudoUserSession Access SDK Class Constructor Creates User Sessions Intermittently Causes Severe Performance Degradation
- Oracle Access Manager 11g (OAM 22.214.171.124.5) - OAM SDK 126.96.36.199
- PseudoUserSession Access SDK class constructor creates user sessions
- Custom access client uses the PseudoUserSession Access SDK class to perform password checks without creating a user session as documented in the Oracle Fusion Middleware Access SDK Java API Reference for Oracle Access Management Access Manager 11g Release 2 (11.1.2) E27136-01
- Most of the time this works as expected. However, twice in the last day it was observed the PseudoUserSession class generating hundreds of sessions associated with the certain identity (this was observed in the OAM console) while the OAM_SESSION database table showed only one unified session for the identity.These events occur sporadically but cause severe performance degradation to the environment.
- Tried deleting the sessions from the console, but new sessions quickly appeared.
- Only cycling the OAM servers handling the requests cleared the condition.
- According to the documentation, PseudoUserSession should not be creating these sessions.
