Restrictions:

Do not install on a symlink. Installing in such a location may impact life cycle operations such as patching and scaling out. Also, it will impact the functioning of your additional OMS.
You must not set the ORACLE_HOME and ORACLE_SID environment variables. You must ensure that the Oracle directories do NOT appear in the PATH.
The Enterprise Manager Cloud Control Installation Wizard installs Java Development Kit (JDK) 1.7.0_80 and Oracle WebLogic Server 12c Release 1 (12.1.3.0) by default. A preinstalled JDK or Oracle WebLogic Server is not supported from 13c Release 1 onwards.
You must ensure that the Oracle WebLogic Server 12c Release 1 (12.1.3.0) installed by the Enterprise Manager Cloud Control Installation Wizard is dedicated for Enterprise Manager Cloud Control. You must not have any other Oracle Fusion Middleware product installed in that Middleware home.
Enterprise Manager Cloud Control cannot coexist with any Oracle Fusion Middleware product in the same Middleware home because the ORACLE_COMMON property is used by both the products.
As a prerequisite, you must have an existing Oracle Database to configure the Management Repository.
If you install the OMS and the Oracle Database, which houses the Management Repository, on the same host, then when you reboot the host, the OMS and the Management Agent installed with it will not automatically start up. You will have to manually start them.
In addition to the mandatory plug-ins, you can optionally install other plug-ins available in the software kit (DVD, downloaded software). The installer offers a screen where you can select the optional plug-ins and install them. However, if you want to install some plug-ins that are not available in the software kit (DVD, downloaded software), then refer to Section 5.5.1
If you are installing on an NFS-mounted drive and creating the OMS instance base directory (gc_inst) on that NFS-mounted drive, then after you install, move the lock files from the NFS-mounted drive to a local file system location. Modify the lock file location in the httpd.conf file to map to a location on a local file system.
