Editing the Parameter File

The parameter file contains both values that you set during the installation process and values that are set by default. The default values are set in the master server. They include such values as the number of devices that can be used during a backup (BEX_MAXDRIVES) and whether to use encryption (BEX_ ENCRYPTION). For more information on these values, see Chapter 16: Configuring Defaults. If you want to override any of these values when working with Oracle, do the following:

1. Using a text editor, open the file named job_name.BEX located in the BEX product directory of the Oracle node. For UNIX, the file is named sbt11cfg.BEX.

2. Follow the instructions in this file which explain how to change values.

For example, to send data to two drives at once, do the following.

1. Using a text editor, open job_name.BEX (for Windows) or sbt11cfg.BEX (for UNIX).

2. Find the line that contains BEX_MAXTASKS, and enter a space and then “2” directly after BEX_MAXTASKS on the same line.

3. Find the line that contains BEX_MAXDRIVES, and enter a space and then “2” directly after BEX_ MAXDRIVES on the same line.

4. This example also requires you to edit the RMAN backup script. In the RMAN backup script, you need to specify that two data streams will be sent at once. This is done by allocating two channels.

   allocate channel d1 type=’sbt_tape’;
   allocate channel d2 type=’sbt_tape’;

Note. When defining Oracle Backup and Restore jobs in DPX, ensure that job names are unique across all Oracle clients. If two clients simultaneously start Oracle backup jobs with the same name, one of them might fail.
