How to Check Patch Applied Status in Oracle Applications?


From Oracle Applications Release 11i to 12.1.x, Patch application Status can be queried from ad_bugs or ad_applied_patches tables

Query to check whether patch is applied on a instance.

SQL>select bug_number,creation_date,last_update_date from apps.ad_bugs where bug_number='&patchnum';

SQL> select PATCH_NAME,CREATION_DATE from apps.ad_applied_patches where PATCH_NAME='&patchnum';

What is difference between above two Queries?

Suppose, we applied a patch which has multiple bugfixes.The details of all bugs fixed by the patch are listed in ad_bugs table.
In Contrast,ad_applied_patches table give info only about the patches which are applied through adpatch utility.


From Release 12.2, Online Patching utility(adop) is used for Patching application Filesystem.

Querying the data from ad_bugs or ad_applied_patches tables may not give correct information.Because, online patching can be aborted anytime prior to Cutover Phase.
ad_bugs or ad_applied_patches tables may contain entries for patches which are started through adop and later aborted.

The below query gives accurate Information about Patch Applied Status in R12.2

select AD_PATCH.IS_PATCH_APPLIED(\'$release\',\'$appltop_id\',\'$patch_no\',\'$language\') from dual;

example sql:
SELECT adb.bug_number,ad_patch.is_patch_applied('11i', 1045, adb.bug_number)
FROM ad_bugs adb
WHERE adb.bug_number in (22498647);

or for single app tier installations:
select ad_patch.is_patch_applied('R12',-1,22498647) from dual;

Sample Output:

EXPLICIT = applied
NOT APPLIED = not applied / aborted


Login to Database node as the database os user

Set environment using commands below

$export ORACLE_HOME=/u01/app/oracle/product/112

$export PATH=$PATH:$ORACLE_HOME/Opatch

$which opatch
==>It should give output like /u01/app/oracle/product/112/Opatch

$opatch lsinventory -invPtrLoc $ORACLE_HOME/oraInst.loc

== This gives list of all patches applied to the ORACLE_HOME

$opatch lsinventory -invPtrLoc $ORACLE_HOME/oraInst.loc|grep 988765

==> To check if a particular patch is applied to the ORACLE_HOME
