one-off patch

A one-off patch is an interim patch that is:

• Available for downloading from OracleMetaLink as an individual patch (it is not included in a patch set).

• Installed using a separate script supplied with the patch (it is not installed using OPatch).

• Used for older versions of Oracle products such as Oracle Database Server release 9.0.1.x and earlier.

• Not detected by Enterprise Manager after it is applied, and is not reported in the Enterprise Manager user interface.

The version number of the patched product is not updated when a one-off patch is applied. Multiple one-off patches can be installed for a given version of a product.

A one-off patch is a bug fix or set of bug fixes made available to customers who for business reasons cannot wait until the next patch set or new product release to get a fix.

One-off patches have been replaced by interim patches applied by OPatch for newer releases of Oracle products.
