OPatch in Oracle 11g
You should be aware that OPatch is tool sensitive to the version. You cannot use the
OPatch tool from one release to patch another release. Oracle 11g introduced several
new options. The next three images show the OPatch syntax in 11g, how it changed
from the 10g release, and which options were added in this release.
Here you can see from the syntax summary that there were many more options
added, and in the next two images, the syntax of the new options is shown. The
util commands are depicted in the next image. The commands available are used
to apply SQL commands, clean up the backup, perform file copies, restore an Oracle
Home, or perform other remove or rollback actions.
