Scheduler

This section provides a step-by-step guide to installing, configuring, and using the Scheduler.

Configuration

Note – all actions required for setting up and configuring emCA Scheduler should be done using administrator privileges

Environment Variables For scheduler.properties

This file is used to configure database related properties like dialect, driver class name, URL, Username, password (database user should have full privilege to the schema created for emCAScheduler) as well as logs.

Variable name: EMCA_SCHEDULER_CONFIGURATION_PATH

Variable value: location of property files (scheduler.properties)

For Linux

For setting the environment variable in Linux, run the following command.

sudo -H gedit /etc/environment

It will open the environment folder and set emCAScheduler path inside that

EMCA_SCHEDULER_CONFIGURATION_PATH for scheduler.properties file .

Once the Environment variable is set for scheduler.properties, the user can open the scheduler.properties to configure various options which includes configuring of connection to emCASheduler well as logs.
