Now since you know basics of patch (If not read my previous posts, its quite important to know patch basics before starting to apply patch )
By now you might know that you use utility adpatch to apply oracle apps patch and adadmin, admrgpch, adctrl to manage/control your patch . Depending on you AD version (i.e. AD.H or AD.I.1 .. AD.I.4) you will have different options available with adpatch . Otherwise you can use interactive option to apply/see basic options (Interactive means adpatch will ask you required field values by displaying some suggestions to you)
First lets discover some major options available with adpatch.
adpatch option=[option1,option2, ….optionN]
Below is option value with explanation
options=noautoconfig If you are applying number of patches out of which 4-5 patches run autoconfig then use this option & run autoconfig in last patch or manually (This will save your patching timing , first patch performance tip )
compiledb(def) or nocompiledb Use no compiledb if you have multiple patch then compile database objects in last patch
compilejsp(def) or nocompilejsp Use no compilejsp if you have multiple patch then compile jsp in last patch
copyportion Tells adpatch whether to run commands normally found in a copy driver.
databaseporion Tells adpatch whether to run commands normally found in a database driver.
generateportion Tells adpatch whether to run commands normally found in a generate driver
hotpatch Tells AutoPatch to apply a patch regardless of whether the Oracle Applications system is in maintenance mode.
integrity Tells adpatch whether to perform patch integrity checking, which verifies that the version of each file referenced in a copy action matches the version present in the patch (There are overheads with this)
maintainmrc Tells adpatch whether to automatically maintain the MRC schema after running actions normally found in the database driver. The MRC schema is only maintained if the MRC feature is enabled
prereq Tells adpatch whether to perform prerequisite patch checking prior to running patch driver files that contain actions normally found in the copy driver. (With lateset AD patch , default behaviour is changed from prereq to noprereq)
forcecopy The forcecopy command copies the files in a patch to the Applications file system without comparing the version number of the patch files with existing files
Since you know basics of apps patch & options available Next I will tell how to apply patch & fix errors if any .
