Before Configuring a High Availability (HA) Pair
Note:
When you configure an HA pair, you must use the same password for both
Oracle® Enterprise Session Border Controllers.
Before configuring the parameters that support HA, complete the following steps.
Establish the physical connections between the
Oracle® Enterprise Session Border Controllers. Avoid breaking the physical link (over the rear interfaces) between the
Oracle® Enterprise Session Border Controllers in an HA node. If the physical link between the
Oracle® Enterprise Session Border Controllers breaks, they will both attempt to become the active system and HA will not function as designed.
Confirm that both
Oracle® Enterprise Session Border Controllers are set to the same time. Use the ACLI
show clock command to view the system time. If the
Oracle® Enterprise 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® Enterprise Session Border Controllers, so that they have a common stratum time source.
HA nodes use specific ports for HA interfaces. See the documentation for the hardware that you use.
For ACLI configuration, you need to know the target names of the
Oracle® Enterprise 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® Enterprise Session Border Controller boot parameters.
Note:
The target name is case sensitive.
Devise virtual MAC addresses so that, if a switchover happens, existing sessions are not interrupted.
