OEM 13c - Summer 2019 Announcements. You can manage ATP and more!!


Here are some exciting announcements for OEM 13c.

First, keep in mind that you should upgrade your OEM 13c to the latest version (13.3PG). I discussed some new features of this version in a previous post (here!) .

Now to the good news.

1. Oracle Database 19c has been certified as a OEM Repository Database (OMR). This means that is time to upgrade your repository to a long term support release.
More info : EM 13.3C: Certification of 19c Database as an EM Repository Database and as a Managed Target (Doc ID 2541711.1)


2. Oracle EM 13.3.2 Bundle Patch (BP) is available. You must keep up with patching if you don't want to encounter issues down the road.
More info: Enterprise Manager Cloud Control Database Plugin 13.3.2.0 Bundle Patch Bug List (Doc ID 2554474.1)


3. The latest EM 13.3.2 BP 3 has support for Oracle Autonomous Database (ATP-D). So, if you are running ATP in dedicated mode and you want to use OEM to manage your DB, is time to patch!!


Thanks,
Alfredo

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

Oracle Enterprise Manager 13.3.2 Database Plugin New Features (Flash and JET)


Oracle EM 13.3 PG was released April 28th 2019. This new (plugin only) release contains 8 new plugins including a new version of the DB plugin.

After installing these plugins we noticed several changes in behavior for the DB targets.

1.    All pages that used Adobe Flash now use Oracle JavaScript Extension Toolkit (JET)
2.    Top Activity and Emergency Performance pages were completely removed from the Performance menu

At the beginning was weird to use just ASH analytics instead of Top Activity page but all the key information is there.

There’s an option to revert 3 JET pages back to Flash if needed. This can be done through emctl commands. All this information can be found on MOS 2422790.1

Also, if you really need the old Top Activity page you can still access it using a direct URL link. For this follow MOS 2528627.1 for more details.

Thanks,
Alfredo

Unable to Extend OEM 13.3 Domain to Add an Additional OMS

While trying to add an additional OMS to the current OEM 13.3 GCDomain using the provisioning console there’s an error in the Install homes step.

The error contains the following message:

Caused by: oracle.sysman.oii.oiif.oiifb.OiifbEndIterateException:
oracle.sysman.oii.oiif.oiifb.OiifbEndIterateException: SEVERE:Values for the following variables could not
be obtained from the command line or response file(s):
MYORACLESUPPORT_USERNAME(MyOracleSupportUsername)
Silent install cannot continue.


This issue is related to Bug 28290139 and the workaround can be found in MOS 2432095.1
After performing the workaround the OMS addition job needs to be executed from scratch. This resolves the issue.

Thanks,
Alfredo
