Oracle Fusion Applications' Enterprise
scheduler

Fusion Applications provides a scheduling engine called the Oracle Enterprise Sched-
uler. This is embedded within Oracle Fusion Applications and does not require a
separate installation. The Oracle Enterprise Scheduler provides a comprehensive
package of scheduling features for Oracle Fusion Applications. The jobs that can be
scheduled using this scheduler are as follows:

• Java packages

• OS based scripts

• PL/SQL packages

This combination of job types accommodates almost any kind of scheduling job
needs. This includes simple OS-level commands and scales up to complex function-
ality that can be coded within Java. The PL/SQL option allows database-specific func-
tionality that needs to be executed.

Details about all scheduled jobs are stored in the metadata repository. This repository
can be queried for job status as well as reporting purposes. This metadata repository
is embedded within the Oracle Fusion Applications database.

The architecture of Oracle Enterprise Scheduler

The Oracle Enterprise Scheduler uses a combination of processes and queues to per-
form its functions. The high-level architecture is as follows:

The primary component is Runtime Module . This is the core engine of the scheduler.
It processes scheduling requests by updating the metadata repository. It puts jobs to
be processed in the Wait Queue . The Request Dispatcher polls the Wait Queue and
