Applies to:Oracle GoldenGate - Version 22.214.171.124.0 and later
Information in this document applies to any platform.
Integrated Replicat Process is Hang.
In the top of OEM Top Activity we see following SQL:
"DELETE FROM SYS.STREAMS$_APPLY_PROGRESS WHERE APPLY#=:1 AND ((LENGTH(COMMIT_POSITION) < LENGTH(:2)) OR ((LENGTH(COMMIT_POSITION) = LENGTH(:2)) AND (COMMIT_POSITION < :2)))"
The top wait of this SQL was "read by other session"
If you kill the replicat process and start it again, then the Wait event will be changed to below,
The top wait here was "enq: SR contention"
