Request For Recommended NFSTAB Settings For Archive Logs & DataPump Export Files Output to NFS Mount

Recently, we have implemented “nfstab” changes to our Linux-based Oracle database servers. These changes involved our NAS “NFS” mounted disk that is used for RMAN backup sets.

Accordingly as Oracle recommends from Doc ID 117597.1 , the “actimeo=0” parameter was removed from our “/bkup” mounted NFS disk (see below). This mounted NFS volume is used for backupsets that are written by all of our RMAN backups via the command “backup recovery area to destination ‘/bkup’”. This has resulted in a substantial reduction in overall run time, backing up our backupsets on primary FRA (not NFS) to secondary backupsets on NFS.

This now leads me to inquire about other Oracle database (output) files and Oracle’s recommendations for these files which reside on NAS “NFS” mounted disks. In particular, I am interested in knowing the correct settings for archive logs (see attachment's nfstab parameters in BLUE) and datapump export dump files (see attachment's nfstab parameters in GREEN) – each one is mounted on a separate NFS mount point. While reviewing another document,

Howdy, Stranger!
