Oracle 11.2.0.2 的新特性

Enhanced Patch Set Installation

Starting with the release of the 11.2.0.2 patch set for Oracle Database 11g Release 2, Oracle Database patch sets are full installations of the Oracle Database software. Note the following changes with the new patch set packaging:

• Direct upgrades from previous releases (11.x, 10.x) to the most recent patch set are supported.

• Out-of-place patch set upgrades, in which you install the patch set into a new, separate Oracle home, are the best practices recommendation. In-place upgrades are supported but are not recommended.

• New installations consist of installing the most recent patch set, rather than installing a base release and then upgrading to a patch release.
