I did that. The error is what I wrote it was. Also, there is no corruption here. The "datapatch" utility is a bug ridden piece of s...oftware which is unreliable and problem ridden. It will take some time for the  utility to stabilize.  Clients that don't have problems are not much of a comfort for me who do have a problem.

There are many of us who patch all the time for different clients and have no problems at all with datapatch, quarterly or one-offs.

You definitely need to look at your log files as to what the specific error is.

Hi Mladen,

The patching indeed became awkward since the good old sql upgrade scripts were replaced by datapatch. But I’m afraid, there is no way back, and leaving the databases unpatched isn’t a sustainable option.

datapatch invokes “opatch lsinventory” which basically generates some shell scripts for loading the inventory.xml into the database to check what needs to be done. In the past, there have been concurrency problems, because the generated files weren’t unique ( ) . The files in /u00/oracle/orabase/product/12.2.0.x.x/cfgtoollogs/opatch/lsinv/ should provide you more information about the error.

What worked for me is to start the datapatch with -apply and –force options to bypass the opatch invocations. You can specify the patch numbers after –apply. I tested this on many releases for non-cdb and multi-tenant.

Alternatively, if your database is multi-tenant, you could try patching the containers one by one – to avoid concurrency. (I haven’t tried this yet.)

Best regards,

I tried patching plain vanilla Oracle 12.2 on OL 7.7 and patch installation went fine. However "datapatch" part did not work:

So, I did what the message suggests:

SQL> select dbms_sqlpatch.verify_queryable_inventory from dual;

ORA-20001: Latest xml inventory is not loaded into table

So, I went to Oracle Support and looked for the message above. No problems, I am not the first one to encounter this:

datapatch Fails with "ORA-20001: Latest xml inventory is not loaded into table" due to Block Corruption "ORA-01578" (Doc ID 2364930.1)

Here is the solution:

a) Fix the corrupted blocks and validate SYSAUX datafile.
Note: You need to restore from valid rman backups or datapump exp/imp.

b) Re-run datapatch


./datapatch -verbose

So, I've had a fully functional Oracle DB, I install October patches and now I have to do recovery? What idiot got rid of catbundle PSU apply? I have been patching Oracle 11g for years and now I have all sorts of problems with Oracle 12.2 and Oracle 18.8? Do we really need a patching utility that causes unnecessary problems? I rolled back the patches and will not apply any more patches to 12.2 until Oracle comes up with the sure fire way to fix the "datapatch" problems and repopulate the tables from "lsinventory".
