adpatch

Modes of adpatch:  
Interactive mode
Non-Interactive mode
Test mode

Interactive Mode:  
It is the default mode of adpatch when we don’t use anything. We can apply patch in this mode by going into patch directory and simply type adpatch in command prompt and hit enter.

Non-Interactive:
$adpatch Interactive=no (It uses default files to store prompt values and can be applied from patch directory.)

Test Mode:
$adpatch apply=no (This mode is purposely used to check the what exactly patch is doing and will do everything without actually changing anything.)

PreInstall Mode:
$adpatch preinstall=y  (When we apply patch in preinstall mode, it updates all AD utilities befre upgrade or update.)

Adpatch Options:
noautoconfig, nocompiledb, nocopyportion, nocompilejsp, nodatabaseportion, nogenerateportion, hotpatch, nolink, nogenform, nomaintainmrc, noprereq
