In a UNIX development environment, the CAS Service can be started from the command line. In a UNIX production environment, however, Oracle recommends starting it from inittab.

In UNIX you run the CAS Server using cas-service.sh, located in usr/local/endeca/CAS/<version>/bin. You can write a script that calls cas-service.sh and is referenced in inittab.

When writing your script, it is recommended as a best practice that you run the CAS Service as a user other than root.

This sample script (named start_cas_service.sh) sets the ENDECA_USER variable to the “endeca” user and then issues an su command to change to the “endeca” user:

#!/bin/sh
ENDECA_USER=endeca
CAS_ROOT=/usr/local/endeca/CAS/<version>
CAS_WORKSPACE=/usr/local/endeca/CAS/workspace

# change to user endeca
su $ENDECA_USER -c "cd $CAS_ROOT/bin; \
     $CAS_ROOT/bin/cas-service.sh >> $CAS_WORKSPACE/logs/cas-service-wrapper.log 2>&1"

The start_cas_service.sh script is then referenced in inittab with an entry similar to this example:

ecas:2345:respawn:/usr/local/endeca/CAS/<version>/bin/start_cas_service.sh

When writing your startup script, keep in mind that it is server-specific, and therefore its details (such as paths and user names) depend on the configuration of your server.
