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=”″

This last command will generate a RPM in the /tmp directory called: “oracle-agt-”   << 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-
  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.


Mass Promote code is in GIT Hub – https://github.com/harry2040/OEM12cMassPromote

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

MOUS15 is here !!!

If you are in the Indiana, Michigan, Illinois, Ohio or Canada region and want to see and experience great Oracle user and technical presentations, networking and hands-on workshops, please register to the Michigan Oracle User Summit (#MOUS15), on Wednesday, November 18th at Schoolcraft college in Livonia, Michigan (www.mous.us).    Its a full day of presentations (45) that include Big Data presentations, Hyperion presentations, JDEdwards, Oracle Applications, Middleware (SOA), Database (Oracle12c, RAC, others) and 2 hands-on workshops – #cloneattack and #racattack.   We also have 13 Oracle Ace and Ace directors, Rich Niemiec of Rolta will be our keynote speaker.   Please visit our website (www.mous.us) or guidebook for more details on the conference content.

So not only do you get some great user and technical presentations, but you get 2 great hands-on workshops – Clone Attack and Racattack (www.racattack.org).

Clone attack (www.delphix.com ) – did you ever want to create development databases from production with a small footprint and dynamic way ?   Well come to MOUS15 and create many development databases on your own PC.

RACATTACK – (www.racattack.org) – Racattack allows you to create a 12c RAC database on your own PC, yes, you too can have your own RAC database on your pc.

Wait there is more !! – WE ARE ON GUIDEBOOK – http://www.guidebook.com (Look for MOUS) its free !!

Lastly, this conference is a great way to network with other Oracle users, a full day of presentations, hands-on workshops, great food , education and its priced reasonably ($50 pre-register, $75 at door).

Hope to see you at the conference and please contact me with any questions,

Cloud 12c Upgrade issues and resolutions

In the process of upgrading to EM12c Cloud control Version 3, i received a few errors that delayed the upgrade by months.   With the help of Oracle support, i finally resolved it today and finished he upgrade.

Error  #1 – “em target policy error”  

Fix – under the sysman account – “exec emd_maintenance.ENABLE_EM_SECURITY_POLICIES”  <==== FIX FOR Error

This was due to missing information below (BEFORE ERROR).

Executing Prereq Action

executing Action: select count(*) from (select ‘EM_TARGET_POLICY’ from dual where not exists (select policy_name from dba_policies where object_owner=upper(?) and pf_owner=upper(?) and object_name IN (‘MGMT_TARGETS’,’EM_MANAGEABLE_ENTITIES’)))

=========NEXT ERROR ================

After that was fixed, received the next error (at about 60/70 % upgraded)
