cachefs

Should you use CacheFS?

• Is your data “stable” and read-only?

• Do you have spare local disk resources on your clients?

• If you use CacheFS to front NFS applications, do your

binaries remain in the cache following an unmount?

If not, are you willing to force them to remain cached?

WARNING – Patch CacheFS Prior to Using

Ø Just prior to 11i releasing, several critical and serious CacheFS

defects were discovered. All known CacheFS defects have since

been fixed. It is strongly recommended that patch PHNE_25627,

or a superseding patch, be installed before using CacheFS on 11i.

As with most system configuration issues, the decision to use CacheFS should be

made by an experienced system administrator who is familiar with the applications

used by the client.
