How do you check patch is applied or not?

To check wether patches applied or not. We will have to simply check it using below query.

To find sigle patch information:-

SQL> SELECT ab.bug_number,ad_patch.is_patch_applied('R12',-1, ab.bug_number) FROM ad_bugs ab WHERE ab.bug_number='2343455';

To check multiple patches, Please use below query:

SQL>SELECT ab.bug_number,ad_patch.is_patch_applied('R12',-1, ab.bug_number) FROM ad_bugs ab WHERE ab.bug_number in ('4564335','5456765',
'3453235','2345641','23234567','34542345','67563456','4345432');

To check patches in multinode environment.

SQL> SELECT ab.bug_number,apt.node_name,ad_patch.is_patch_applied('R12', apt.APPL_TOP_ID, ab.bug_number)
FROM ad_bugs ab,
( select APPL_TOP_ID, n.node_name
from ad_appl_tops t, fnd_nodes n
where instr(UPPER(t.NAME),UPPER(n.node_name)) >= 1 ) apt
WHERE ab.bug_number in ( '&BUG_ID');
