ORA-24093: AQ agent SCHED$_% not granted privileges of database user %

These days, when trying to add dbms_scheduler notifications for different user I was getting this strange error:

BEGIN
 DBMS_SCHEDULER.add_job_email_notification (
  job_name   =>  'APPOWNER.MYJOB',
  recipients =>  'me@company.com',
  events     =>  'job_started, job_succeeded'
  );
END;
/

ORA-24093: AQ agent SCHED$_XXX not granted privileges of database user APPUSER
ORA-06512: at "SYS.DBMS_ISCHED", line 8296
ORA-06512: at "SYS.DBMS_SCHEDULER", line 4353
ORA-06512: at line 3

The issue is that “secure queue access must be granted to an Oracle Database Advanced Queuing (AQ) agent explicitly for both enqueue and dequeue operations. You grant the agent these privileges using the ENABLE_DB_ACCESS procedure in the DBMS_AQADM package” (http://docs.oracle.com/database/121/STRMS/strms_trprop.htm#STRMS1046)

So, problem solved with this:

BEGIN
  DBMS_AQADM.ENABLE_DB_ACCESS(
    agent_name  => 'SCHED$_XXX',
    db_username => 'APPUSER');
END;
/

See you next week!

Online Data Patch Apply with multiple Databases on same Oracle Home: OPatch failed with error code 26

Hi all,
Tricky question, right? It’s easier than you think…
Actually, we don’t commonly think on those situations in first place, but it’s pretty common, specialy if considering server consolidation situations.

The trick is to use clause util enableOnlinePatch insted of apply after first database applying.
In this example I’m applying on-off patch 14084247 in online mode. Check:

# First Database:

[oracle@PRODSERVER 14084247]$ opatch apply online -connectString ORA11:sys::
Oracle Interim Patch Installer version 11.2.0.3.4
Copyright (c) 2012, Oracle Corporation.  All rights reserved.


Oracle Home       : /opt/oracle/app/product/11.2.0/db_1

OPatch succeeded.

All good, right?
Let’s see applying to second database with same command:

Second Database:

[oracle@PRODSERVER 14084247]$ opatch apply online -connectString OTHERORA11:sys::

Recommended actions: Please use 'opatch util applySql' for sql related patches or 'opatch util enableOnlinePatch' for online patches to add sids to already installed patch(es).

OPatch failed with error code 26

Beeep!
So, simply use clause util enableonlinepatch as per below.

Second Database (right way):

[oracle@PRODSERVER 14084247]$ opatch util enableonlinepatch -connectString OTHERORA11:sys:: -id 14084247
Oracle Interim Patch Installer version 11.2.0.3.4

Log file location : /opt/oracle/app/product/11.2.0/db_1/cfgtoollogs/opatch/opatch2017-04-03_14-20-53PM_1.log

Invoking utility "enableonlinepatch"
Installing and enabling the online patch 'bug14084247.pch', on database 'OTHERORA11'.

OPatch succeeded.
[oracle@PRODSERVER 14084247]$

Ok, that’s it for today.

See you next week!
