Replicat is Slow on ACFS (Doc ID 1998170.1)

Last updated on APRIL 13, 2015

Applies to:

Oracle GoldenGate - Version 11.2.1.0.2 and later
Information in this document applies to any platform.

Symptoms

The replicat is running very slow on the ACFS filesystem.

It has been seen that when the replicat checkpoint file (<OGG_Home>/dirchk/<replicat>.cpr) is on ACFS , the performance of the replicat degrades. Also, it may not be necessary  the other replicats suffer with the same performance problem.

When checking the trace/trace2 file, we could see high amount in checkpointing (which includes updating the checkpoint file, reading trail files ).

Truss on the replicat may show high time being spent on the fsync.
