rt4s shell script

The rt4s shell script is used to start or stop the server from init(1) processing, and must be run as part of the system boot procedure. You must change the rt4s shell script if the server is installed in a directory other than the default directory, /opt/IBM/InfoSphere/Optim/rt. You must also change the rt4s shell script if the server is run under a user account other than root.

To modify the environment variables that specify the server directory and the user account, edit the following places in the script:

Symbolic links

A symbolic link allows a file name in one directory to point to a file in another directory.

To start and shut down the server as part of init processing, you must create symbolic links to the rt4s script in the following directories:

  • rc2.d, where 2 is the run level for startup
  • rc1.d, where 1 is the run level for shutdown

The location of the rc2.d and rc1.d directories is platform‑specific:

  • Under Solaris and Linux, the location is /etc.
  • Under HP-UX, the location is /sbin.
  • Under AIX®, the location is /etc/rc.d.

Use the ln command to create symbolic links, as follows: ln -s actualfile linkname.

actualfile
File to which a symbolic link points.

In this case, specify rt4s.

linkname
Name of a symbolic link that is used to point to a file.

In this case, point links named S99RT4S and K07RT4S to rt4s.

Solaris or Linux

To start and shut down the server during Solaris or Linux init processing, create symbolic links to the rt4s script in directories /etc/rc2.d and /etc/rc1.d.

  1. Log in as the root user.
  2. From the console, enter the following commands:
     ln -s  /opt/IBM/InfoSphere/Optim/rt/sbin/rt4s  /etc/rc2.d/S99rt4s
     ln -s  /opt/IBM/InfoSphere/Optim/rt/sbin/rt4s  /etc/rc1.d/K07rt4s

HP-UX

To start and shut down the server during HP-UX init processing, create symbolic links to the rt4s script in directories /sbin/rc2.d and /sbin/rc1.d.

  1. Log in as the root user.
  2. From the console, enter the following commands:
     ln -s  /opt/IBM/InfoSphere/Optim/rt/sbin/rt4s  /sbin/rc2.d/S99rt4s
     ln -s  /opt/IBM/InfoSphere/Optim/rt/sbin/rt4s  /sbin/rc1.d/K07rt4s

AIX

To start and shut down the server during AIX init processing, create symbolic links to the rt4s script in directories /etc/rc.d/rc2.d and /etc/rc.d/rc1.d.

  1. Log in as the root user.
  2. From the console, enter the following commands:
     ln -s  /opt/IBM/InfoSphere/Optim/rt/sbin/rt4s  /etc/rc.d/rc2.d/S99rt4s
     ln -s  /opt/IBM/InfoSphere/Optim/rt/sbin/rt4s  /etc/rc.d/rc1.d/K07rt4s
