You are required to configure the proxies and repos.

Configure the http proxy in /etc/yum.conf file and also export the proxy's address to the environment.

1. In /etc/yum.conf, add the following line:

   proxy=<proxy_server>

2. Export the proxy's address.

   export http_proxy=<proxy_server>
   export https_proxy=<proxy_server>

3. Enable the required proxies in yum.conf.

   curl -O https://yum.oracle.com/public-yum-ol7.repo
   mv public-yum-ol7.repo /etc/yum.repos.d/public-yum-ol7.repo
   yum-config-manager --enable ol7_latest ol7_UEKR4 ol7_developer_EPEL ol7_optional_latest ol7_addons ol7_UEKR3 ol7_UEKR5 ol7_UEKR6 

You must create a backup of the Mediation Engine (ME) and Mediation Engine Connector (MEC) before you begin upgrade.

Session Monitor provides the feature of backing up the configuration of Mediation Engine (ME) servers by using Configuration Savepoints.

For more information, see Configuration Savepoints section in Settings chapter of Operations Monitor User Guide.

Perform the following tasks to collect present data for comparing incase of any issues:

• Take Platform Setup Application (PSA) Screenshots

  Go through each page of PSA and make screenshots of the page for comparing with post-upgrade in case of issues.

• Potential Customized Files

  Ensure to make a backup copy of all the following potential customized files:

  • /etc/mysql - Configuration files for MySQL stored in this directory. Make a copy of the entire directory. This is not required for probes.

  • /etc/iptego for version 3.3 or /opt/oracle/ocsm//etc/iptego for version 3.4 and later - Configuration files for Session Monitor services are stored here. Make a copy of the entire directory.

• Any other configuration files that you consider to have changed on the server.

• Capture current system diagnostics with MySQL dumps and all the hardware system configuration.
