The system uses database DIPs to communicate with local and remote databases. These DIPs need to be configured with information regarding where and how to access the databases. You can administer the DIP configuration from the Web Administration interface (Configuration Management > JDBC Administration), or using the dbconfig command.
By default, call information is stored in Call Data Handler (CDH) text files on the Avaya IR system. In Web Administration, this CDH text file is called File CDH. If the system has a local Oracle database, you can administer the system to store CDH records in the local Oracle database. In Web Administration, this is called Database CDH. You can administer both CDH configurations (File CDH and Database CDH), but only one configuration can be active.
If the Avaya IR system does not have a local Oracle database, the CDH text files can be uploaded to a remote database. The upload can be scheduled to run at a convenient (low traffic) time using a cron job.
Note:
Because enabling Database CDH for a remote database may result in heavy LAN traffic, Avaya does not recommend doing this in most cases.
