Using the Maintenance Utility
A shell script utility called serv is included with the ESS distribution at the <less_install_dir>/ess/ directory. This serv
script can be used to manage the following processes of L-ESS Server:
 PS Monitor Application (PSMON)
 L-ESS
This utility can report the status of the L-ESS process on the system or it can be used to stop an instance of L-ESS
process.
Important: L-ESS must always be started with the serv script command.
Following are the options available with the serv script:
./serv { start | stop | forcestart | forcestop | switch | version | status[
<resource_name | resourcegroup_name> ] }
