Critical Patch Advisory
If your environment has Enterprise Manager Grid Control you can use the Critical
Patch Advisory, which is a valuable tool to diagnose the whole environment and
diagnose among the targets which ones require a CPU to be applied. Grid Control
can connect to Metalink and download the required patches. It also supports an
offline operation mode for those targets that don't have a direct Internet connection
available. Note that this requires both the Metalink account and the Configuration
Management Pack option. The Critical Patch Advisory is also available in Oracle 11g.
Hot patching (11g only)
Normally when a patch is applied the Oracle services must be shutdown. This means
a downtime and a maintenance window must be open while the operation takes
place. The DBA must ensure that the process will be successful on the first attempt
otherwise there it must be a fall back procedure in place.
Among the high availability features provided by 11g, Oracle introduced the Hot
patching concept. Hot patching allows the DBA to install, enable, and disable a patch
online without disruption to Oracle services. Hot patches don't require instance
shutdown, and they are installed with the traditional OPatch tool. This tool can
detect conflicts between hot patches.
