Enterprise Replication Event Alarms

Certain Enterprise Replication errors and other actions generate event alarms. You can use event alarms specific to Enterprise Replication to automate many administrative tasks.

You can set your alarm program script to capture Enterprise Replication class IDs and messages and initiate corrective actions or notifications for each event. For example, you can add a chunk to the queue data sbspace or dbspace if you detect (using class ID 31) that the storage space is full.

Most event alarms operate in the background. For events that operate in the foreground, the session that triggered the alarm is suspended until the alarm program execution completes. For information on setting alarm program scripts to capture events, see Event Alarms.

Many Enterprise Replication event alarms are enabled by default, but most state change event alarms are disabled by default. You can control which Enterprise Replication event alarms are enabled with the CDR_ALARMS environments variable.

The following table lists the information about Enterprise Replication event alarms:

The class ID is an integer value identifying the category of the event.
The event ID is a unique identifier for the specific message.
The class message provides general information about the event.
The specific message provides detailed information about the event.
The severity describes the seriousness of the event on a scale from 1 to 5, where 5 is the most serious.
Whether the event operates in the foreground and explanations for the events.
Whether the event is disabled by default.
