Making a backup copy of system parameter values

The system parameter values are stored in the $SYSPARM_DIR/rd.data file. When you have reset system parameter values (either by using System Configuration or by using Pack Configuration) and achieved a satisfactory system, you should make a backup copy. Then, if something happens to the parameter file, the parameters can be restored from the backup file. It is also a good idea to make a backup copy before making a big change to the system, such as installing a new digital trunk adapter.

Start

Log on to AIX as dtuser.
Making sure the environment is set correctly: Activate an AIX window.
Type the following command and press Enter:
```
   echo $VAE
```
If you are logged on as the Blueworx Voice Response user, the system displays:
```
   /usr/lpp/dirTalk
```
If it does not, type the following command and press Enter:
```
   . /usr/lpp/dirTalk/tools/vae.setenv
```
Be sure to leave a space between the period and the slash before usr.
Copying the file: Type the following command and press Enter:
```
    cp $SYSPARM_DIR/rd.data $SYSPARM_DIR/rd.data.bak
```
where rd.data.bak is a filename of your choice.

You now have a backup copy of the system parameter file. You can now archive this file to removable media such as tape.
