OEM12C Deployment and Mass Promotion

OEM12C Deployment and Mass Promotion

I was privileged to be a speaker at the Rocky Mountain training days #td17 on the topic of “Automagically” Deploying EM12c Agents and Mass promotion of targets once the hosts have been added.

The presentation is attached, but in a nut shell, using EM12C’s RPM generation and using Puppet we are able to push out agents, the moment the machines are built and validated.

The first step is to log into the OMS machine and generate the RPM using EMCLI (After logging into emcli )

> emcli get_supported_platforms  <== This will get the information for building the RPM’s

 

emcli get_agentimage_rpm -destination=/tmp -platform=”Linux x86-64″ -version=”12.1.0.5.0″

This last command will generate a RPM in the /tmp directory called: “oracle-agt-12.1.0.5.0-1.0.x86_64.rpm”   << notice the version # and platform in the name

Now that the RPM is ready, we use Puppet to copy and to install the RPM on new machines.

A few notes about puppet installs with RPMS

  • We use a standard location / directory
  • Only run if the standard location is NOT in place
  • Only run if “emwd.pl” is not in place
  • Verifies the correct ownership of the directories
  • Uses oraInventory for location

There are 2 steps for the puppet process

  1. apply RPM – >> rpm -ivh oracle-agt-12.1.0.5.0-1.0.x86_64.rpm
  2. create agent.properties file – With host name, default password, etc.
  3. run – /etc/init.d/oracle-agt RESPONSE_FILE=/usr/lib/oracle/agent/agent.properties
  4. When Step 3 finishes, there should be a new OMS entry for that host and connected to the OMS.

Last step – Just added recently – (Not part of presentation) is to perform a mass promotion of non-host targets like databases, listeners, etc.

Thanks again to #td17 for a great conference and the opportunity.

RMAN Upgrade – ORA-00439: feature not enabled…

How many people have received letters from Oracle that have stated that partitioning and / or Fine-grained auditing were turned on for Oracle 12C and they had to remove it otherwise pay a higher license fee or penalties.   Well if you haven’t, your lucky as many customers have received this kind of letter, recently.

Well many have received the notice and then recompiled/de-installed the partitioning and/or fine grain auditing option on the databases that have contained a RMAN catalog user/schema.

When they removed the partition and/or the fine grain auditing and tried to upgrade the RMAN Catalog for the new Oracle 12c databases you will get this error:

Recovery Manager: Release 12.1.0.2.0 - Production on Thu May 26 13:08:02 2016

RMAN> connect catalog catalog_user/PW@Database;

PL/SQL package catalog_user.DBMS_BA version 12.01.00.02 in RCVCAT database is too old

RMAN> upgrade catalog

recovery catalog owner is catalog_user
enter UPGRADE CATALOG command again to confirm catalog upgrade

RMAN> upgrade catalog

RMAN-06004: ORACLE error from recovery catalog database: ORA-00439: feature not enabled: Partitioning
RMAN-06004: ORACLE error from recovery catalog database: ORA-00439: feature not enabled: Fine-grained access control
RMAN>

Well if you have received this error, I hope you have a backup of the database, as this will corrupt you RMAN catalog. Well at least it corrupted our RMAN catalog and many others.

ISSUE:

New RMAN catalog – Oracle 12.1.0.2 requires Partitioning, fine-grained auditing and other Enterprise edition options. Per Mike Dietrich’s BLOG, Going forward with Oracle 12c, you need to use Enterprise Edition for RMAN or Infrastructure databases:

“A separate single instance Oracle Database can be installed and used as an infrastructure repository for RMAN, Oracle Enterprise Manager Cloud Control, Automatic Workload Repository (AWR) Warehouse, Global Data Services Catalog, and Grid Infrastructure Management Repository without additional license requirements, provided that all the targets are correctly licensed. It may not be used or deployed for other uses.”

https://blogs.oracle.com/UPGRADE/entry/rman_catalog_requires_ee_in

SOLUTION:

#1 – the RMAN catalog must be in its OWN Oracle 12.1.0.2 EE database – no other applications – Partitions need to be included
#2 – DBMS_LOB and UTTL_HTTP Must be present
#3 – Execute this script before upgrading the catalog: SQL> @$ORACLE_HOME/rdbms/admin/dbmsrmansys.sql
#4 – no Partitioning license required
#5 – Make sure you have a backup
#6 – p20432873_121020_Generic.zip – is a patch to fix the corrupted RMAN catalog due to Oracle 12c requirement – basically its a different recover.bsq script to fix the corruption. – This is only if its currently corrupted.   One of the few bugs, that i was able to create an actually see a patch created for it – thank you Oracle.
#7 – See MOS Note:1927265.1 – this has more information

Please review Mike Dietrich’s Blog above regarding licenses and more information – https://blogs.oracle.com/UPGRADE/entry/rman_catalog_requires_ee_in

Hope this helps.   Again, please backup your rman catalog before upgrading .

Multitenant – Oracle 12c Standard Edition

Im Re-blogging this information, as i heard this at Collaborate 15, that non-multitenant databases will be deprecated in Oracle 13, not sure if its true, but here is some good information, if it is true…..

==============================================

Can you have Oracle Multitenant in Oracle Standard Edition 12.1.0.2 SE2?

No, you can’t as Oracle Multitenant is a licensable option for Enterprise Edition (EE) databases only.   

But wait a second …

You can do Oracle Single Tenant with SE2 of course meaning you can have one active pluggable database within one container database at a time. That is possible and does not require any additional licenses.

See the DBCA (Database Configuration Assistant) screen when you’ll try to create a container database:

More information? 

You’ll find more information about the differences in handling and such between Oracle non-CDB, Oracle Single Tenant and Oracle Multitenant databases in this presentation:
