Stephan,Please query V$ACTIVE_SESSION_HISTORY for the USER_ID (translated from DBA_USERS view) for the time period from a few seconds before and during when you received the ORA-03135 error. Specifically, display the EVENT, P1, P2, and P3 of each ASH row retrieved, in addition to SESSION_ID, SESSION_SERIAL#, and PROGRAM.
Please let us know what you find? Thanks! -Tim On 11/10/14 2:59, Stephan Uzzell wrote:
