Step-by-step guide

Preparation:

  1. Consult official documentation: https://docs.oracle.com/cd/E22693_01/doc.12/e55580/patches.htm#CMTAR254
  2. Check MOS note 888888.1.
  3. Check 10GB disk space is free in /u01 on both nodes
  4. Check there is at least 200% of disk space available for all Grid and Database homes. The update performs a clone of the Oracle Home in /u01.

It is not necessary to shut down anything manually before the update, not even the databases.

Installation:

  1. Download the patch itself from Oracle. The location is provided in MOS note mentioned above
  2. Upload the patch file to a temporary location ob both nodes
  3. run "oakcli unpack -package path" where path is the location of the patch file on both nodes
  4. run "oakcli validate -c ospatch -ver 12.1.2.5.0" on the first node, where "12.1.2.5.0" is the version of the patch to install
  5. run "oakcli update -patch version" on the first node

The oakcli logfiles are in: /opt/oracle/oak/log/oda1/oak/oakd.log

Caveats

oakcli may get stuck for several reasons, for example, if it runs out of disk space during the upgrade. oakcli check for 10G free disk space in /u01 before cloning the Oracle Home. But an Oracle Home may be larger then 10G when, for example, some audit or log files are present.

If the update process is interrupted, the whole installation may be stuck and unrecoverable. A typical situation is:

[root@oda1 ~]# oakcli show version -detail 
Reading the metadata. It takes a while... 
unclosed token at line 5367, column 6, byte 298999 at /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/XML/Parser.pm line 187
root@oda1 ~]# oakcli show vm
OAKERR:6003 OAK is in upgrade Mode

While the VMs do not start any more.

The only solution Oracle Support found for this situation was:

  1. Remove excessive new Grid_Home on both the nodes that should not be there 
    1. rm -fr /u01/app/11.2.0.4 
  2. Replace the central inventory ("/u01/app/oraInventory/ContentsXML/inventory.xml") on both nodes from last backup, or execute on both nodes the following commands (change nodename1,nodename2 with your ODA host nodes name): 
    1. export NEW_GI_HOME=/u01/app/11.2.0.4/grid 
    2. export ORACLE_HOME=$NEW_GI_HOME 
    3. $OLD_HOME/oui/bin/runInstaller -detachHome -silent -local ORACLE_HOME=$NEW_GI_HOME 
    4. export OLD_GI_HOME=/u01/app/11.2.0.3/grid 
    5. export ORACLE_HOME=$OLD_GI_HOME 
    6. $OLD_HOME/oui/bin/runInstaller -attachHome -silent -local ORACLE_HOME=$OLD_GI_HOME ORACLE_HOME_NAME=OraGrid11gR3 "CLUSTER_NODES=nodename1,nodename2" CRS=true 
  3. Rerun update --GI command. 
    1. oakcli update –patch <patch_number> –gi
