Applying a Release Update in Oracle 19c is supposed to be boring. Binary patch goes in, datapatch runs, you verify, you move on. Most of the time that’s exactly how it goes.
But every now and then, datapatch throws you something cryptic — an error that doesn’t point anywhere useful, and you’re left staring at the log wondering if Oracle itself broke something. That’s exactly what happened here with the 19.30 RU, and the actual fix took about two minutes once we knew where to look.
The Error That Started It All
After the binary patch for Oracle 19.30 went in cleanly, datapatch ran and hit this:
Unsupported named object type for bind parameter at
/u01/app/oracle/product/19.0.0/dbhome_1/sqlpatch/sqlpatch.pm line 6147.
If you’ve never seen this before, your first instinct is probably the same as mine — something’s wrong with the patch itself, or there’s a bug in the SQL patching framework. It reads like an internal Oracle error. The kind of thing that sends you to MOS for an hour looking for patches on top of patches.
That instinct is wrong. The error message is genuinely misleading here. The real problem had nothing to do with the patch or sqlpatch.pm. It was hiding somewhere else entirely.
Here’s the full datapatch output for context:

The One Command That Changed Everything
Before rerunning datapatch, try this first:
$ORACLE_HOME/OPatch/datapatch -sanity_checks
Most DBAs know about this flag but skip it because things “usually work.” Don’t skip it. Run it before every datapatch execution, and definitely run it when something fails. Here’s what it showed us:
Check: Database component status - OK
Check: PDB Violations - OK
Check: Invalid System Objects - OK
Check: Tablespace Status - WARNING
CDBPROD:
| TABLESPACE_NAME | TABLESPACE_SIZE | FREE_TABLESPACE | USAGE |
| SYSTEM | 32767.98 | 97.31 | 99.7 |
Check: Temp file exists - ERROR
The default temporary tablespace must have at least one temp file associated.
IBA:
| COUNT |
| 0 |
Check: Temp file online - ERROR
The default temporary tablespace does not have any online temp files.
CDBIBA:
| STATUS |
| DEFAULT TEMPFILE(S) STATUS IS/ARE: OFFLINE OR NOT EXIST |
There it is. Two ERRORs, both pointing at the same thing: the IBA PDB had a TEMP tablespace, but absolutely no tempfiles associated with it. Zero. The tablespace existed on paper, but there was nothing backing it.
That’s what was killing datapatch. When it tried to run its internal SQL operations inside the PDB, it needed TEMP space and found none. The “unsupported named object type” error was a symptom, not the cause.
Confirming It Directly
Connect into the affected PDB and check for yourself:
ALTER SESSION SET CONTAINER = IBA;
SELECT name FROM v$tempfile;
no rows selected
That’s all you need to see. No tempfile means datapatch cannot work in that PDB. Simple as that.
The Fix
For an immediate resolution:
ALTER TABLESPACE temp ADD TEMPFILE;
That works and will unblock you. But if this is a production system — or anything you care about — take the extra 30 seconds to do it properly:
sql
ALTER TABLESPACE temp
ADD TEMPFILE '/u01/app/oracle/oradata/CRMV12/temp01.dbf'
SIZE 2G
AUTOEXTEND ON
NEXT 500M
MAXSIZE UNLIMITED;
The reason to be explicit: datapatch is not the only thing that needs TEMP space. Large patching operations, index rebuilds, sorts, and hash joins all draw from TEMP. If you let Oracle pick defaults and the file is tiny, you’re setting yourself up for a different failure later. Specify the path, size it appropriately, and turn autoextend on.
Verify Before Moving On
Quick sanity check after adding the tempfile:
SELECT file_name, bytes/1024/1024 MB, autoextensible
FROM dba_temp_files;
Make sure the file shows up, autoextensible says YES, and the size is what you specified. Takes ten seconds and removes any doubt.
Don’t Assume It’s Just One PDB
This is the part people miss. If one PDB had this problem, others might too — especially in environments where PDBs were cloned, unplugged and plugged in, or created from scripts that didn’t include tempfile creation.
From the CDB, check all of them at once:
SELECT con_id, tablespace_name, COUNT(*) AS tempfile_count
FROM cdb_temp_files
GROUP BY con_id, tablespace_name
ORDER BY con_id;
Any PDB with a tempfile_count of 0 will fail during datapatch, guaranteed. Fix all of them before you rerun the patch — otherwise you’ll hit the same wall in a different PDB and have to start over.
Rerun Datapatch
Once every PDB checks out:
bash
$ORACLE_HOME/OPatch/datapatch -verbose
With the TEMP issue resolved, the SQL patch applies cleanly. No more line 6147 errors, no more misleading output. Done.
Why Does This Even Happen?
This isn’t a bug in Oracle 19.30. The patch itself is fine. What happened here is a configuration gap in the PDB — one that was probably there for a long time and never caused a visible problem until datapatch tried to use TEMP space during SQL patching.
The most common reasons a PDB ends up without a tempfile:
- It was cloned from another PDB and the tempfile didn’t carry over properly
- It was created with a script that set up the TEMP tablespace but forgot to add the file
- The tempfile existed at some point but was manually dropped or went missing
Datapatch just exposed a pre-existing problem. It happens more often than you’d think, especially in environments with lots of PDBs that were created at different times by different people.
Make This Part of Your Pre-Patch Checklist
Going forward, run datapatch -sanity_checks before every RU application. Not just when you suspect something might be wrong — every time. It takes under a minute and it catches issues like this one before they turn into failed patches and late-night troubleshooting.
Beyond the sanity check, verify TEMP across all PDBs as a standard pre-patching step. It costs nothing and eliminates an entire category of patching failures.
The lesson from this one isn’t complicated: when datapatch gives you a cryptic internal error, the problem almost certainly isn’t what the error says it is. Start with -sanity_checks, let Oracle tell you what’s actually broken, and you’ll usually find something fixable in a couple of minutes.
