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,
