Before You Configure

Note:

When you configure an HA pair, you must use the same password for both Oracle Communications Session Border Controllers.

Before configuring the parameters that support HA, complete the following steps.

1. Establish the physical connections between the Oracle Communications Session Border Controllers. Avoid breaking the physical link (over the rear interfaces) between the Oracle Communications Session Border Controllers in an HA node. If the physical link between the Oracle Communications Session Border Controllers breaks, they will both attempt to become the active system and HA will not function as designed.
2. Confirm that both Oracle Communications Session Border Controllers are set to the same time. Use the ACLI show clock command to view the system time. If the Oracle Communications Session Border Controllers show different times, use the system-timeset command to change the time.

   Oracle recommends that you use NTP to synchronize your Oracle Communications Session Border Controllers, so that they have a common stratum time source.

3. HA nodes use specific ports for HA interfaces. See the documentation for the hardware that you use.
4. For ACLI configuration, you need to know the target names of the Oracle Communications Session Border Controllers making up the HA node. The target name of the system is reflected in the ACLI’s system prompt. For example, in the ORACLE# system prompt, ORACLE is the target name.

   You can also see and set the target name in the Oracle Communications Session Border Controller boot parameters.

   Note:

   The target name is case sensitive.
5. Devise virtual MAC addresses so that, if a switchover happens, existing sessions are not interrupted.
