Automatic Restart

Automatic Restart

On Linux and UNIX, you must set up the Dynamic Data Masking Server to restart when the host machine restarts. Dynamic Data Masking works in conjunction with the database to process database requests. If you do not set up automatic restart, no database client application will have access to the database after the host machine restarts.
If you do not set up automatic restart, you must manually restart the Dynamic Data Masking Server after you restart the host machine.
The Dynamic Data Masking installation directory contains an rc.d script file,
S99ddmsrv
, that you can install in the runlevel initialization directories so that the script file will run at startup. A symbolic link references the
S99ddmsrv
 script file, which starts the Dynamic Data Masking Server when the host machine restarts or changes runlevels.
On Linux and UNIX, log in as the superuser and create symbolic links to the
S99ddmsrv
 script file in each of the runlevel directories to ensure that the script file will run at startup. The initialization process differs depending on the platform. If you are unsure where or how to install the rc.d script file, contact the vendor for instructions.
For example, on Red Hat Enterprise Linux 6, create symbolic links for the appropriate runlevels with the following command format: 
ln -s <Dynamic Data Masking installation directory>/S99ddmsrv /etc/rc.d/rc<runlevel>.d/S99ddmsrv
If you have more than one Dynamic Data Masking Server on a machine, you can add each server to the automatic startup. Create a symbolic link with a unique name that references the
S99ddmsrv
 script file for each Dynamic Data Masking Server.
For example, on Red Hat Enterprise Linux 6, you might run the following commands:
  • ln -s /home/rhel6/Informatica/DDM1/S99ddmsrv /etc/rc.d/rc3.d/S99ddmsrv1
  • ln -s /home/rhel6/Informatica/DDM2/S99ddmsrv /etc/rc.d/rc3.d/S99ddmsrv2
  • ln -s /home/rhel6/Informatica/DDM1/S99ddmsrv /etc/rc.d/rc5.d/S99ddmsrv1
  • ln -s /home/rhel6/Informatica/DDM2/S99ddmsrv /etc/rc.d/rc5.d/S99ddmsrv2
Before you uninstall Dynamic Data Masking, you must remove the symbolic links that you created in the runlevel directories.
On Windows, the Dynamic Data Masking installer configures the Dynamic Data Masking Server to restart when the host machine restarts.
