ZFSSA EM12c Plugin Pro-Tip

When adding ZFSSA targets to #EM12c, be sure to uncheck "kiosk user" for the oracle_agent user in ZFSSA. Doc ID 1609846.1

The versions 12.1.0.3.0 and 12.1.0.4.0 of the ZFS plugin require additional access to  the ZFS appliance over that provided by the workflow used to configure the user. 
In addition to configuring Oracle ZFS Storage Appliance by running "Configure for Oracle Enterprise Manager Monitoring" workflow on the storage, the Oracle ZFS Storage Administrator must also perform the following additional steps:
  1. Log in to the Sun ZFS Appliance as root.
  2. Go to Configuration --> User.
  3. Select the oracle_agent user and click "Edit".
  4. Uncheck the option "kiosk user".
  5. Click "Apply".
Once the oracle_agent has the kiosk limitation removed, monitoring can proceed normally.

Upgrading EM12c to 12.1.0.3: Active Directory Authentication Quirks

We recently upgraded our EM12c 12.1.0.2 installation to 12.1.0.3. This service was configured to authenticate logins against our Active Directory server via LDAP. However, after upgrading we found that authentication stopped working, even after recreating the Active Directory Authenticator (as required). I could see the list of users from AD, but could not authenticate them in EM!

In this post I'm going to share what we did to diagnose the problem and what other hurdles we encountered on the way.

Up until this incident, I had practically zero experience troubleshooting Oracle middleware/weblogic/OMS problems, so I knew it was going to be frustrating, even with Oracle Support's assistance. The key was knowing where to look.
