By default adpatch does not take any clause, but there are some clauses that you could use with adpatch
Running a patch in test mode
You can use the apply clause with adpatch to specify weather to run the patch in TEST mode or not, when you run the patch in test mode it does not do any changes but runs generates a log fiule with all the actions it would have performed.
$adpatch apply=n|y
The default is apply=y

$adpatch preinstall=y
The default is preinstall=n
Other Options with adpatch
You can use the options clause to specify some of the other options available with adpatch.
Autoconfig
You can use the ptions=noautoconfig top specify autopatch that you do not wish to run autoconfig as a part of the patch application. This can be useful when applying a large number of patches when they are not merged. By default autoconfig is run as a part of adpatch.
$adpatch ptions=noautoconfig Checkfile
The chekfile option of adpatch tells adpathc to check for already executed exec, SQL, and exectier commands.You can use ptions=nocheckfile skips this check, however this can cause performance overheds so should be used only when specified.
$adpatch ptions=nocheckfile

$adpatch ptions=nocompiledb
