Configuring Cached ODM

Configuring Cached ODM requires first enabling Cached ODM for a file system.

After enabling Cached ODM, it can be configured in two ways:

■ The primary configuration method: turn caching on or off for all I/O on a

per-file basis.

■ The secondary configuration method: adjust the ODM cachemap. The cachemap

maps file type and I/O type combinations into caching advisories.

See “Tuning Cached ODM settings for individual files” on page 76.

See “Tuning Cached ODM settings via the cachemap” on page 77.
