28. INSTALLING ENTERPRISE MANAGER 13.1.0.0
➤ Use DB template to create repository database (DB version
supported: 12.1.0.2)
➤ Do not unzip the binaries files. Execute the
em13100_<platform>.bin file to invoke the installer
➤ Use EM installer to install WLS
Always refer to “Official Installation Guide”
Check if the files have correct bytes/checksum values
28

29. LET THE INSTALLER HANDLE THE REST

30. USE “INITIAL SETUP CONSOLE”
After you install, visit Initial Setup Console to complete
“recommended” post-install tasks.

31. MONITORING AND INCIDENT HANDLING
➤ Create a copy of the system default Incident Rule Sets. The
default rule sets are locked.
➤ Create monitoring templates, set critical metric values.
➤ Create groups. Assign monitoring templates to groups and set
different notification types based on groups.
➤ Update all notification so only critical alerting is performed.
➤ Use the EM Console to view non-critical warnings

32. CHECK “MANAGEMENT PACK ACCESS”
Disable auto licensing to prevent license violations.
32

33. TAKE REGULAR BACKUPS
You need to back up following components:
➤ The Oracle Management Service: Filesystem backup of
installed software* and backup of OMS configuration:
$OMS_HOME/bin/emctl exportconfig oms
➤ The Management Repository: Backups can be taken using
RMAN
➤ The software library: Taking file system backups daily is
sufficient in most cases.

34. KEEP YOUR ENTERPRISE UP TO DATE
➤ Oracle Recommended Patches for Enterprise Manager Base Platform
(MOS Doc ID 822485.1 needs update)
➤ Use omspatcher (Patch 19999993) to patch OMS
➤ Database Recommended Patches (MOS Doc ID 756671.1)
➤ Keep your plugins and agents up to date using “Self-Update”
➤ Agents are patched via EM
➤ Create a patch plan, check for conflicts and deploy to a test server
➤ Create a gold image and use it to mass deploy
➤ Get to know EMDIAG Troubleshooting Kits Master Index (MOS
Note 421053.1) - hopefully they will be released for EM13c soon
