Ever wondered how to check what patches are installed for a database home, without actually having access to the database server?
In 12.1 Oracle introduced a package DBMS_QOPATCH that allows you to check what patches have been applied to the Oracle Home the database is running from.
This package accesses the OUI (Oracle Universal Installer) patch inventory to provide you with the information.
The package has lots of subprograms, which you can check out here:
What we are interested in today, is to check the patches installed in the database, without actually being connected to the database server.
set pagesize 0
spool installed_patches.out
select xmltransform(dbms_qopatch.get_opatch_lsinventory,
dbms_qopatch.get_opatch_xslt) as Patch_Info from dual;
spool off
Sample output:

Make sure you spool the content to a file, as there is a lot detail in the output, same as running opatch lsinventory -detail.
Another useful command of the same package is to find out the Oracle Home and the inventory location:
set pagesize 0
set long 1000000
select xmltransform(dbms_qopatch.get_opatch_install_info,
dbms_qopatch.get_opatch_xslt) from dual;
Oracle Home : /u01/app/oracle/product/19.0.0/dbhome_1
Inventory : /u01/app/oraInventory
One more thing to check for the Oracle home and the database is, if the patch has been applied in the database, aka was datapatch run in the database, after the home was patched. To find the answer for this, you need to query: DBA_REGISTRY_SQLPATCH view.
SQL> select patch_id, action, description, action_time
from dba_registry_sqlpatch order by action_time;
PATCH_ID ACTION
DESCRIPTION ACTION_TIME

With this information at your fingertips, you can create a script that tells you everything: the patches applied to the Oracle Home and the patches applied in the database, without connecting to the database server!
