Selecting a notification handler
Before setting up a notification, you need to decide on the kind of notification handler you want to use to receive notifications. Notification handlers specify how you want a certain notification to be handled.
You can set a notification so that it is handled through email, message queues, or user exits. For example, you may want to send messages to an email address, relay a message to a message queue, or you may prefer to set up a user exit that triggers certain operations upon specific CDC Replication events.
Depending on the CDC Replication product
you have installed, you can select certain notification handlers in
the Notifications dialog box:
- Message Queue
- You can indicate that you want to relay a message to a specified message queue when a certain type of message is generated. You have the option of relaying that message to up to ten different message queues. To specify a message queue, you need to specify both the name of the message queue and the library where it resides.
- User Exit/User Handler
- You can indicate that you want to launch a user exit program when a certain type of message is generated. Note that you are responsible for creating the user exit program and ensuring that it works properly.
- You can indicate that you want to send the generated message to an email address. Depending on the type of datastore, SMTP (Simple Mail Transfer Protocol) and MAPI (Messaging Application Program Interface) can be used for sending email messages. Unless explicitly stated, each setting applies to both SMTP and MAPI.
- Event Log
- You can indicate that you want to send the generated message to the Windows application log.
- CHCPRINT
- You can indicate that you want to send the generated message to the CHCPRINT spool file provided with the CDC Replication Engine for Db2® for z/OS®.
SYSLOG
- DB2® for z/OS
- You can indicate that you want to send the generated message to the operator system log maintained on zSeries servers.
