Synchronizing the Registration Cache

ECB Sync data includes the Oracle Enterprise Communications Broker's registration cache. The user can enable registration cache sync via a checkbox within the Sync config settings under the ECB Sync icon.

When enabled, the Oracle Enterprise Communications Broker presents its registration cache to all ECB Synch agents every nine minutes. Each ECB Sync agent uses this data to create a separate, ECB Sync-only registration cache table that includes contacts and the ECB from which it learned the cache entry.

When a call comes for a contact found in the ECB Sync-only registration cache, the Oracle Enterprise Communications Broker receiving the call adds a URI parameter to the request URI of the TO header and forwards the message to the Oracle Enterprise Communications Broker in the table. This URI parameter informs the target Oracle Enterprise Communications Broker that is must only use its registration cache for routing this call. This parameter appears as follows.

TO sip:[e-mail];orcl-regonly=true

In these cases, both Oracle Enterprise Communications Brokers forward the call. The Oracle Enterprise Communications Broker receiving the call uses all other routing sources to route the call, including LDAP, LST and UserDB. The Sync agent Oracle Enterprise Communications Broker routes the call using its registration cache, and skips all other routing sources, including LDAP, LST and UserDB.

Enable ECB Sync Operations

Enable ECB sync when you want one Oracle Enterprise Communications Broker (OECB) to share information with another OECB. For example, to share information about users, routes, dial plans, and agents. To use ECB Sync, you must enable the service and set the authentication secret. You can optionally enable the system to sync the configuration and the registration cache from one OECB to another.

The secret that you enter in the ECB Sync configuration must match the secret used by the ECB sync agents.

1. Access the Sync Config Settings configuration object.
   Configuration tab, System Administration section, Sync, Sync Config Settings.
2. On the Modify Configuration Settings page, do the following:

   Enable sync	Select to enable ECB sync operations.
   Secret	Click Set. Secret—Enter the secret that you use for authenticating with OECB peers. Confirm secret—Re-enter the secret. Click OK.
   Configuration	(Optional)—Select to enable the system to sync the configuration from one OECB to another.
   Registration	(Optional)—Select to enable the system to sync the registration cache from one OECB to another.

3. Click OK.
