Oracle Enterprise Manager 13.3 problems discovering Exadata targets

If you are on the latest Exadata plugin for EM 13.3 (well, even the 13.2 version of the plugin). Be aware that there’s a bug where if the Exadata nodes’ names are longer than 7 characters, you cannot discover them.

EM just throws a weird error with below legend: 

SEVERE: makeTargetsXml for each rack#: 1 e=java.lang.StringIndexOutOfBoundsException: String index out of range: -1

The solution is to apply the latest (March 2019) Bundle Patch to the agents running on the Exadata’s compute nodes.

More info on below MOS note:  

Exadata Discovery Fails With “No New Component Is Discovered. Click Cancel” (Doc ID 2477624.1)  

Another good excuse to keep your EM system up to date.  

Happy patching.  

Thanks,
Alfredo

OMS responded illegally [ERROR- Failed to Update Target Type Metadata] in 13c R2

I want to discuss about this OMS error coming from the agent’s heartbeat status. The agent shows with an unreachable status but is actually up and running.

Agent is Running and Ready
In this case the agent is not able to upload the metadata because is different in the OMS.
This is mainly due to a patch in the agent side that is missing in the OMS. By mistake I applied the latest bundle patch to the agent before applying it to the OMS.
Just another proof that any patches have to be installed to the OMS first then the agents.
Thanks,

Alfredo

Upgrade OPatch for OEM 13c R2 Agents

Opatch utility has to be updated often as Oracle delivers regular updates to it. I was used to version 12 and it only required an overwrite of the OPatch directory. Well, not anymore with version 13c R2.
I will walk you through an OPatch upgrade from 13.8 to 13.9 version.
First export your agent ORACLE_HOME:
$: export ORACLE_HOME=/u01/oracle/oemagent/agent_13.2.0.0.0/
Verify the current OPatch version:
$: $ORACLE_HOME/OPatch/opatch version
OPatch Version: 13.8.0.0.0
OPatch succeeded.
Download and unzip the 13.9 version in a temporary directory:
$: unzip p6880880_139000_Generic.zip
Archive:  p6880880_139000_Generic.zip
   creating: 6880880/
  inflating: 6880880/README.txt
  inflating: 6880880/opatch_generic.jar
  inflating: 6880880/version.txt
As you can see, now we have some zip files and a java file. Execute java to upgrade OPatch as follows:
$: $ORACLE_HOME/jdk/bin/java -jar opatch_generic.jar -silent oracle_home=$ORACLE_HOME
