Symptoms

 Replicate process hangs. The query to v$session shows transaction locks on the replicate session. Example as seen on session waits are

 

SID EVENT                                    PROGRAM                                          MODULE                                           SQL_HASH_VALUE LAST_CALL_ET
---------- ---------------------------------------- ------------------------------------------------
      513 enq: TX - row lock contention            replicat@dalccadb01 (TNS V1-V3)                  replicat@dalccadb
      523 SQL*Net message from client              replicat@dalccadb01 (TNS V1-V3)                  replicat@dalccadb0
      542 SQL*Net message from client              replicat@dalccadb01 (TNS V1-V3)                  replicat@dalccadb0

 

Restarting the replicate will not help and the tx locks are observed even after a restart.

Killing the session does not help. After replicate restart, the locks are still present
