Starting Momentum (ecelerity)
ecelerity is the main server component of the Momentum Application Server. On start up, the script /etc/init.d/ecelerity start starts Momentum. For details about the available options, see ecelerity.
Note
To run this script, you must have root privileges.
Use ec_ctl to start, stop, or restart this process. For details about this command, see ec_ctl.
It can be useful to execute specific scripts on startup or shutdown. For example, if you have configured the spool directory as a separate filesystem, you might want to make sure that filesystem is mounted before starting Momentum. If Momentum is started up using ec_ctl, startup scripts in the rc.includes directory will be executed.
The rc.includes directory under the /opt/msys/ecelerity/bin directory allows third party module providers and local administrators to add startup and shutdown procedures to the ec_ctl command. For example, use this directory for scripts that initiate database recovery, set environment variables, or check for necessary mount points.
Start scripts must be named start.purpose and stop scripts stop.purpose. ec_ctl will use sh . to include each script named in this format.
The following example illustrates how to check for the spool filesystem. Save it as /opt/msys/ecelerity/bin/rc.includes/start.checkmount.
SPOOL_FS=/var/spool/ecelerity /sbin/mount | /usr/bin/grep -q $SPOOL_FS if [ $? != 0 ]; then echo "Spool filesystem not mounted, aborting." exit 1 fi
