Start Script with -env

Sample Example for starting the Job Scheduler JobScheduler with the an environment variable hellh1. world:

 unix-shell>[install_path]/bin/jobscheduler.sh start -env="hello=world" 
 windows-shell>[install_path]\bin\jobscheduler.cmd start -env="hello=world"

...

Environment Variables Script: jobscheduler_environment_variables.(sh|cmd)

...

The JobScheduler start script reads the environment from the .\user_bin\jobscheduler_environment_variables.(sh|cmd) script.

...

• bin/jobscheduler_environment_variables.(sh|cmd)-example.
• Rename this file

...

• to ./user_bin/jobscheduler_environment_variables.(sh|cmd) to make it effective.
• For Unix make sure that ./user_bin/jobscheduler_environment_variables.sh is readable and executable.
• Edit ./user_bin/jobscheduler_environment_variables.(sh|cmd) if you always want to start the JobScheduler with additional environment variables. If you want to start the JobScheduler Windows service with the -env option then a reinstall is required (see below).

Sample Example snippet of [install_path]/user_bin/jobscheduler_environment_variables.(sh|cmd) for adding the an environment variable helloworld:

Code Block
SCHEDULER_PARAMS="... \"-env=hello=world\" ..." ... rem windows sample setSET SCHEDULER_PARAMS=...%SCHEDULER_PARAMS% -env="hello=world" ... SET SCHEDULER_START_PARAMS=%SCHEDULER_START_PARAMS% -env="hello=world" ...

For this close the services dialog (services.msc) if necessary and ...

• stop the Job Scheduler if necessary

and environment variables that have been used for installation. During the Windows JobScheduler setup a Windows Service is installed that has to be re-installed in order to make new environment variables effective.

For this:

• stop the JobScheduler if it is running:

 windows-shell>[install_path]\bin\jobscheduler.cmd stop

• remove the Job Scheduler JobScheduler service:

 windows-shell>[install_path]\bin\jobscheduler.cmd remove

• install the Job Scheduler JobScheduler service with -env option or edit the jobscheduler_environment_variables.cmd file like as stated above

 windows-shell>[install_path]\bin\jobscheduler.cmd install -env=hello=world
 ...or...
 windows-shell>[install_path]\bin\jobscheduler.cmd install
 

• start the Job Scheduler JobScheduler service:

 windows-shell>[install_path]\bin\jobscheduler.cmd start_service
