When NFS Server Is Down, Oracle Server Freezes With No Errors In Alert Log File (Doc ID 1316251.1)

Last updated on AUGUST 04, 2018

Applies to:

Oracle Database - Enterprise Edition - Version 10.2.0.4 and later
IBM AIX on POWER Systems (64-bit)

Symptoms

Each of the Oracle instances on AIX has a NFS mount point for backup purposes. It is mounted with following options:

bg,hard,intr,rsize=32768,wsize=32768,sec=sys,noac,rw


When the NFS server is down, the Oracle RDBMS freezes with no errors in alert log file. When the NFS server is up again, the database is working without problems.

Changes

No changes on the environment, just lost NAS connectivity (to NFS server), so the remote directories are not  available.
