Managing schedulers

  • Managing schedulers

    Schedulers are configured using the administrative console, configuration service or scripting and are available to all servers on which a scheduler is visible.

  • Scheduler daemon

    A scheduler daemon is a background thread that searches for tasks to run in the database.

  • Example: Stopping and starting scheduler daemons using Java Management Extensions API

    Use the wsadmin scripting tool to invoke a Jacl script and stop and start a scheduler daemon.

  • Example: Dynamically changing scheduler daemon poll intervals using Java Management Extensions API

    Use the wsadmin scripting tool to invoke a Jacl script and dynamically change scheduler daemon poll intervals.

  • Configuring schedulers

    Before your application can make use of the scheduler service, you must configure a scheduler using the administrative console, configuration service or scripting. Conceptually, a scheduler is similar to a data source in that you must specify various configuration attributes, including a JNDI name where the instance is bound. Once defined, an application using the Scheduler API or WASScheduler MBean can look up the scheduler object and call various methods to manage tasks.

  • Creating the database for schedulers

    Each scheduler requires a database in which to store its persistent information. Schedulers use this database for storing tasks and then running them. The choice of database and location should be determined by the application developer and server administrator.
