NAME

edscheduler - EnduraData Job Scheduler

SYNOPSIS

edscheduler

DESCRIPTION

edscheduler is EnduraData EDpCloud job scheduler process. This process reads the configuration file edscheduler.cfg, parses it when it changes and automatically schedules tasks to run when the specified conditions are met.

Please setup the timezone. Consult $ED_BASE_DIR/etc/readme_timezone.txt for the appropriate time zone for your area and put it in $ED_BASE_DIR/timezone. (Windows use %ED_BASE_DIR%)

Configuration file format edscheduler.cfg

edscheduler.cfg must be created under etc directory located under ED_BASE_DIR.

Configuration file format

The configuration file has the following format:

minute hour day_of_month month day_of_week command [command arguments]

Where: Minute is a number in the range [0 .. 59] or a "*". A star indicates every minute. Hour is a number in the range [0 .. 23] or a "*". A star indicates every hour. day_of_month is a number in the range [1 .. 31] or a "*". A star indicates every day of the month. month is a number in the range [1 .. 12] or a "*". A star indicates every month. 1 is for January, 2 for February, etc.

        day_of_week  is a number in the range [0 .. 6] or a "*". A star indicates every day of the week. 0 is for Sunday, 2 for Monday, ..., 6 is for Saturday.
        command is the command you want to execute, followed by the arguments. The commands must have an absolute path or must be in the PATH environment variable.

EXAMPLE1

        1 * * * * c:\\enduradata\edpcloud\bin\edstat >> c:\logs\stats
        30 23 * * * c:\\enduradata\edpcloud\bin\edjob >> c:\logs\jobs
        1 0 * * * c:\\enduradata\edpcloud\bin\edq -l us2london -n c:\outgoing\london
        15 5 * * * c:\\enduradata\edpcloud\bin\edq -l ".*" -r virginia09 -n c:\images\station19

This example shows that:

(a) we dump the stats to a log file every hour of the day at minute 1 past the hour. (b) we dump the job log to a log file at 11:30 pm every day. (c) we queue the content of directory c:\outgoing\london for distribution to link us2london. We do this every day at midnight, minute 1. (c) we queue the content of directory c:\images\station19 for distribution to all links in receiver virginia09. We do this every day at 5:15 am.

EXAMPLE2

        30 1 * * 0 /usr/local/enduradata/edpcloud/bin/edq -l france -r paris -n /data/fr/paris

This example shows that we queue /data/fr/paris to be sent to link named france and receiver paris. This happens at 1:30 am every Sunday.

Extending the GUI with new schedule operations

The schedule tab in the GUI can configure many operations. It can also be extended to process other operations.

To add custom operations edit SRVROOT/private/ed/templates/scheduler.php and add it as follows and create ednewscript bash script or ednewscript.bat under edpcloud/bin directory.

  <option value="ednewscript" <?php echo $_['operation']=='ednewscript'?'selected="selected"':'' ?>>NewCustomScript</option>

FILES
