Job Scheduler Settings

The Comergent eBusiness System supports the ability to schedule tasks that must be performed at regular intervals as cron jobs. See CHAPTER 39, Job Scheduling Administration for more information on this scheduling feature.

There are two types of cron jobs: system and application.

• System cron jobs are run without session information and without an associated Comergent eBusiness System user. Typically, they are used for low-level background tasks such as garbage collection. System cron jobs do not save their last execution time or execution status to the Knowledgebase because the same job may be run on several servers in a cluster.
• Application cron jobs are used when session information (such as a username or locale) is required to run the job or if audit information might be needed to determine how changes to data objects were made. Application cron jobs are initiated by posting an XML message to the Comergent eBusiness System using the message URL for cron jobs: consequently, to enable application cron jobs, you must take care to set this URL correctly.

  For example, if the main URL used to access the Comergent eBusiness System is:

  http://server:port/Comergent/en/US/enterpriseMgr/matrix

  then set the cron job message URL to:

  http://server:port/Comergent/msg/matrix

  Similarly, if the main URL used to access the Comergent eBusiness System is:

  http://server:port/store/en/US/enterpriseMgr/anderel

  then set the cron job message URL to:

  http://server:port/store/msg/anderel

You can choose whether or not to allow either type of cron job to run on your implementation.

Attention:

Some cron jobs such as the search index builder must be run as an application cron jobs. To support advanced search, you must enable application cron jobs.

Application cron jobs are created specifying a username and password of a Comergent eBusiness System user. You must ensure that the Password data field of the CronConfig data object is not set to store one-way encrypted values.

In a clustered installation of the Comergent eBusiness System, if you want a job to run on all servers in the cluster, then make it a system cron job. If you want the job to be run on only one server in the cluster, then you must make it an application cron job.
