All rights reserved. | Oracle Confidential – Internal/Restricted/Highly Restricted 12 Adding an OMS • You can clone only an existing, running Oracle Management Service 12c that is associated with an AdminServer host. The patches applied on the source OMS are automatically carried over to the cloned instance. • You can clone only one OMS at a time and to only one destination host at a time. If you want to add multiple OMS instances, then you must repeat the installation procedure on each host. • You can clone only when the source host and the destination host are running on the same operating system and architecture. For example, if the source host is a Linux 32-bit host, then the destination host must also be a Linux 32-bit host. Similarly, if the source host is a Linux 64-bit host, then the destination host must also be a Linux 64-bit host. • All general purpose file systems, including OCFS2 and ACFS, are acceptable for storing Enterprise Manager Cloud Control 12c software binaries and OMS instance home files (configuration files in gc_inst). However, OCFS is not considered a general purpose file system, and therefore is not considered acceptable for this use. • You must not install the additional OMS on an NFS-mounted drive. Installing it on an NFS-mounted drive causes the Oracle HTTP Server to restart frequently, which in turn makes the OMS inaccessible. If you are forced to install on such a shared drive, then ensure that the OMS instance base directory (gc_inst) is created in a non-NFS-mounted location. • You can find the OMS and Management Agent entries in the /etc/oragchomelist file for all UNIX platforms except HPUNIX, HPia64, Solaris Sparc. On HPUNIX, HPia64, Solaris Sparc platforms, the entries are present in /var/opt/oracle/oragchomelist. Copyright © 2014 Oracle and/or its affiliates. All rights reserved. | Oracle Confidential – Internal/Restricted/Highly Restricted 13 Server Load Balancer Requirements In order to configure your OMS's in an active/active configuration behind an SLB, your SLB must meet the following requirements: • The SLB must provide support for multiple virtual server ports. Enterprise Manager typically requires that up to 4 ports are configured on the SLB (Secure Upload, Agent Registration, Secure Console, Unsecure Console) • Support for persistence. HTTP and HTTPS traffic between the browser and the OMS requires persistence. • Support for application monitoring. The SLB must be capable of monitoring the health of the OMSs and detecting failures, so that requests will not be routed to OMSs that are not available. Copyright © 2014 Oracle and/or its affiliates.

The current production site is running and active, while the second site is serving as a standby site and is in passive mode. Oracle Data Guard Physical Standby is used to replicate Repository transaction from primary site to standby site. OMS hosts on each site have mount points defined for accessing the shared storage system for the site. Copyright © 2014 Oracle and/or its affiliates.

All rights reserved. | Oracle Confidential – Internal/Restricted/Highly Restricted 16 Backing Up and Recovering Enterprise Manager Software Components • Oracle Management Services (OMS) • Management Agent • Management Repository • Software Library Each component, being uniquely different in composition and function, requires different approaches to backup and recovery. Copyright © 2014 Oracle and/or its affiliates. All rights reserved. | Oracle Confidential – Internal/Restricted/Highly Restricted 17 Backing Up and Recovering Enterprise Manager Software Components - Software Library Backup • The software library is a centralized media storage for Enterprise Manager software entities such as software patches, virtual appliance images, reference gold images, application software, and their associated directive scripts. • The software library storage locations should be backed up periodically using file system backup. • Oracle recommends the backup be performed at a frequency of 1 to 24 hours. Copyright © 2014 Oracle and/or its affiliates. All rights reserved. | Oracle Confidential – Internal/Restricted/Highly Restricted 18 Backing Up and Recovering Enterprise Manager Software Components - Management Repository Backup • Database should be in archivelog mode. Not running the repository database in archivelog mode leaves the database vulnerable to being in an unrecoverable condition after a media failure. • Perform regular hot backups with RMAN using the Recommended Backup Strategy option via the Cloud Control console. Other utilities such as DataGuard and RAC can also be used as part of a comprehensive strategy to prevent data loss. Copyright © 2014 Oracle and/or its affiliates. All rights reserved. | Oracle Confidential – Internal/Restricted/Highly Restricted 19 Backing Up and Recovering Enterprise Manager Software Components - Oracle Management Service Backup • Software Homes Composed of Fusion Middleware Home, the OMS Oracle Home and the WebTier (OHS) Oracle Home and multiple Management Plug-in Oracle Homes. Software Homes changes when patches or patchsets are applied or updates are applied through the new Self Update feature. For this reason, filesystem-level backups should be taken after each patch/patchset application or application of updates through Self Update. You should back up the Oracle inventory files along with the Software Homes and save the output of opatch lsinventory –detail to make it easy to determine which patches are applied to the backed up Oracle Homes. • Instance Home The gc_inst directory, composed of WebLogic Server, OMS and web tier configuration files. The Instance Home can be backed up using the emctl exportconfig oms command. • Administration Server The Administration Server operates as the central control entity for the configuration of the entire OMS instance domain. The Administration Server is an integral part of the first OMS installed in your Cloud Control deployment and shares the Software Homes and Instance Home.The Administration Server is backed up at the same time as the Instance Home, the emctl exportconfig oms command Copyright © 2014 Oracle and/or its affiliates. All rights reserved. | Oracle Confidential – Internal/Restricted/Highly Restricted 20 Backing Up and Recovering Enterprise Manager Software Components - Management Agent Backup • There are no special considerations for backing up Management Agents. As a best practice, reference Management Agent installs should be maintained for different platforms and kept up-to-date in terms of customizations in the emd.properties file and patches applied. Use Deployment options from the Cloud Control console to install and maintain reference Agent installs. • If a Management Agent is lost, it should be reinstalled by cloning from a reference install.
