Oracle GoldenGate Best Practices: NFS Mount options for use with Oracle GoldenGate

The purpose of this document is to outline the file system mount options to use when configuring GoldenGate to run with NFS mounted file system.

Main Article

Unless IO buffering is OFF, NFS mounts should not be used when running any Oracle GoldenGate processes.  The danger occurs when one process registers the end of a trail file or transaction log and moves on to the next in sequence before all the data in the NFS IO buffer gets flushed to disk. The net result is skipped data and this cannot be compensated for with GoldenGate parameter EOFDELAY.

When using an NFS mounted file system with Oracle GoldenGate files, the setting for file system caching or buffered IO must be disabled on both NFS client and server.
