Database Initialization Parameters for Database Service Registration
An Oracle AI Database service automatically registers with the listeners
specified in the LOCAL_LISTENER and
REMOTE_LISTENER parameters.
During registration, the listener registration (LREG) process sends information
such as the service name, instance names, and workload information to the
listeners. When a listener starts after the Oracle instance starts, and the
listener is available for service registration, registration does not occur
until the next time the Oracle AI Database LREG process starts its discovery
routine. By default, the LREG discovery routine is started every 60 seconds.
To override the 60-second delay, use the SQL statement ALTER SYSTEM
REGISTER. This statement forces LREG to register the
service immediately.
Note:
Oracle recommends that you create a script to run the ALTER SYSTEM REGISTER statement immediately after starting the listener. If you run this statement when the instance is registered and all services are currently registered, or while the listener is down, then the statement has no effect.
