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

LET THE INSTALLER HANDLE THE REST

USE “INITIAL SETUP CONSOLE”

After you install, visit Initial Setup Console to complete “recommended” post-install tasks.

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

CHECK “MANAGEMENT PACK ACCESS”

Disable auto licensing to prevent license violations.

32

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.

33

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
