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.

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,

ORA-10997 and ORA-09968 on ASM startup (With NFS)

During a recent hardware upgrade, i received the following error on a ASM (NO-RAC) startup.   It was very confusing, because i was custom to seeing ASM on Storage LUNS and in this case it was using ASM (NO-RAC) and NFS storage.   Unfortunately, as always with late night changes, you don’t notice things until you get fresh eyes on the issue.   A simple “df -kh” would’ve told me that it was NFS, but made too many presumptions.

When i first told about the NFS settings, i thought i needed to restart nfs, but that didn’t work.   Than after getting another fresh pair of eyes from the Linux team, we realized that the directory “/var/lib/nfs” was set to 750???   After some investigation, we saw that puppet was changing it to 750 every 5 minutes, so even when we changed it to 755, it was 750.  so the next question, why ?

Well it appears that FTI requirements are the culprit.  Apparently the auditors don’t understand nfs and O/S’s, probably don’t care either.   Apparently, FTI companies are required to set this to 750…. Now i understand security, but this directory needs to be readable by Oracle to start up the nfs drives and ASM.

Until we get a permanent solution, the linux team offered the following solution:

the setting of 755 is only needed for startup, so the temporary solution is (as root):


root> chmod 755 /var/lib/nfs
root> chatter +i /var/lib/nfs <== protects
root> crsctl start has
== after successful startup ====
root> chatter -i /var/lib/nfs <== takes off the protection

The following is the error description:

grid> srvctl start asm

PRCR-1079 : Failed to start resource ora.asm

[kslwt_validate_gwaitctx: magic], [21313] – “asm_diskstring” > 1024

Recently our staff tried to add disk strings to ASM diskgroups and the strings exceeded 1024 characters. We are on a oracle 11.2.0.4 on redhat linux. In the Docs, it says it should hold up to 4K, but when we added to the asm_diskstrings we got the following error and the ASM DB wouldn’t startup causing our production db to be down:

ORA-0600: [kslwt_validate_gwaitctx: magic], [21313]

We looked many places (Including Metalink and Communities) and couldn’t find a ora-0600 error but did find a ora-7445 with the same code/error.

We opened a ticket and was notified that there is a bug with this error and a patch to fix it.

We were hitting Bug 18273830 where when the asm_diskstring becomes larger than 1024 characters it causes this failure. There is a one-off Patch available on My Oracle Support and 11.2.0.4 which will resolve this problem

Patch 18273830
Release Oracle 11.2.0.4.0
Platform Linux x86-64

Hope this helps, as there isn’t much documentation on this bug/error.

RMAN-03009 Error with ORA-19511

I recently modified the RMAN servers to perform auto backup of the controlfiles, etc. After the change, the incremental’s worked without error.

When I Ran the Full RMAN backup, got the following errors :
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of Control File and SPFILE Autobackup command on ch00 channel at 08/03/2014 18:42:51
ORA-19506: failed to create sequential file, name=”c-2369888563-20140803-ff”, parms=””
ORA-27027: sbtremove2 returned error
ORA-19511: Error received from media manager layer, error text:
Failed to remove, c-2369888563-20140803-ff, from image catalog.

The reason why is the rman backups were NOT using the rman catalog for over a year (Commented out for some odd reason). The RMAN backups were running but without a catalog connection.

So when i added control file auto backup, I received this error.

To FIX:

Connect to RMAN using the rman catalog
run : rman> crosscheck archivelog all;
Run Full backup.

Once the crosscheck cleaned up all the archive logs since 2013, the full backup could be performed.

I also added the RMAN catalog to all the backups on this machine

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)
