10 Upgrading
You can upgrade to the latest version of Oracle Enterprise Manager Ops Center 12c if you are currently using Oracle Enterprise Manager Ops Center 12c.
10.1 Introduction to Upgrading
You can upgrade to the latest version of Oracle Enterprise Manager Ops Center from Oracle Enterprise Manager Ops Center 12c.
Some of the procedures described in this section use the ecadm, proxyadm, and agentadm commands. See Appendix A, "Command Line Administration" for more information about these commands.
-
On Oracle Solaris systems, these commands are in the
/opt/SUNWxvmoc/bin/directory. -
On Linux systems, these commands are in the
/opt/sun/xvmoc/bin/directory.

10.1.2 Planning The Upgrade
Upgrading to a newer version of Oracle Enterprise Manager Ops Center can change the system requirements and affect existing settings and data. Take the following steps to plan your upgrade:
-
Review the Oracle Enterprise Manager Ops Center Release Notes for pre-installation requirements and known issues.
-
Verify that your system meets the system requirements outlined in the Oracle Enterprise Manager Ops Center Installation Guide for Oracle Solaris Operating System or Oracle Enterprise Manager Ops Center Installation Guide for Linux Operating Systems, since some system requirements have changed.
You can use the OCDoctor to check system requirements. See http://java.net/projects/oc-doctor for more information about the OCDoctor.
-
If you made changes to the uce.rc file, the upgrade erases your changes. Copy your changes to the .uce.rc file before beginning the upgrade.
-
If you replaced the self-signed web server certificate for the Enterprise Controller, the upgrade erases your web server configuration changes, and might erase the certificate. Copy the certificate to a safe location before beginning the upgrade. After the upgrade, reapply your configuration changes and copy the certificate to its original location.
Note:
Due to improvements to vServer management, Oracle VM Server for SPARC vServer templates from version 12.1.4.0.0 or earlier will not function in version 12.2.0.0.0 and must be recreated. In addition, a user with the Cloud Administrator role must configure at least one vNet as a boot network before creating any new vServers. See the Virtual Datacenters chapter of the Feature Reference Guide for more information.Note:
If your Enterprise Controller is installed on Oracle Solaris 11, your Oracle Solaris 11 repository must contain the specific version of Oracle Solaris 11 installed on the Enterprise Controller before you begin the upgrade.10.1.3 Database Requirements
Oracle Enterprise Manager Ops Center version 12c can use either an embedded database on the Enterprise Controller system or a customer-managed database. You cannot change the existing database configuration during the upgrade.
The embedded database is configured and managed by Oracle Enterprise Manager Ops Center. The embedded database requires 10 GB of space, plus 240 MB per managed asset, 400 MB per UCE channel, and 20% of the space currently taken up by the /var/opt/sun/xvm/db/mgmt and var/opt/sun/xvm/db/report directories.
You must install and configure a compatible database to use a customer-managed database. Using a customer-managed database requires no additional space beyond that required by the Enterprise Controller.
10.1.4 Upgrading Your Environment
The Oracle Enterprise Manager Ops Center Upgrade Guide includes upgrade procedures for a variety of environments. Several factors will determine the procedure that is most appropriate for your environment. Table 10-1, "Upgrade Procedures by Environment and Upgrade Choices" shows the relevant chapter for you based on your environment and your preferences for the upgrade. Each chapter is a complete upgrade procedure.
Environments with a single Enterprise Controller use a separate procedure from environments with Enterprise Controller High Availability.
You can perform upgrades through the user interface or from the command line.
