Administering Job Servers

Objective

After completing this lesson, you will be able to Configure the Adaptive Job Server.

Adaptive Job Server Services

See the following scenario depicting how to control report distribution using events.

The Adaptive Job Server provides important services that dynamically adjusts its resources based on the current system load. Administrators need to ensure that server status is Running and Enabled after performing common management task such as configuring a destination to send your report to or creating event dependencies to control when reports are processed.

Let’s go over an overview of configurable services, running a schedule and reference server properties.

The following table describes each of the services in the Adaptive Job server.

Adaptive Job Servers

Service	Service Category	Service Description
Authentication Update Scheduling Service	Core Services	Gives synchronization of updates for third party security plug-ins.
Crystal Reports 2020 Scheduling Service	Crystal Reports Services	Processes Crystal Reports 2020 reports.
Crystal Reports Scheduling Service	Crystal Reports Services	Processes Crystal Reports for Enterprise reports.
Destination Delivery Scheduling Service	Core Services	After a job is completed, it publishes the results to a given output location, such as the file system, FTP, e-mail, or a user inbox.
Promotion Management Scheduling Service	Promotion Management Services	Processes scheduled Promotion Management jobs.

Web Intelligence Scheduling Service	Web Intelligence Service	Enables support for scheduled Web Intelligence jobs.

Setting a Schedule for a Crystal Report

You can schedule an SAP Crystal report to run at a future time from the Central Management Console (CMC) or BI Launch Pad.

The following steps describe the process of setting a schedule for a Crystal report:

The web client submits a schedule request in a URL via the web server to the web application server.
The web application server interprets the URL request and determines the request is a schedule request. The web application server sends the schedule time, database login values, parameter values, destination, and format to the specified Central Management Server (CMS).
The CMS makes sure you have the permission to schedule the object. If you have enough permissions, the CMS adds a new record to the CMS system database. The CMS also adds the instance to its list of pending schedules.
The CMS sends a response to the web application server to let it know the schedule operation was successful.
The web application server generates the next HTML page and sends it via the web server to the web client.

Running a Scheduled Crystal Report

The following steps describe the process running a scheduled SAP Crystal Reports 2020 report at a scheduled time:

Process Flow: Running a Scheduled Program Object

When a program is schedule to run, the following steps takes place in the following work-flow diagram.

The CMS sends the schedule request to the Adaptive Job Server. The Adaptive Job Server obtains the program object from the Input FRS.

Then in step 4, the Adaptive Job Server provides the following important service of running a program using the Program Scheduling Services.

Click on the following link to detail the process flow steps when a scheduled program is run.

Adaptive Job Server Properties

The following are the Adaptive Job Server Properties.

General Properties

Property	Description	Default Value
Temporary Directory	Specifies the directory where temporary files are created on when necessary. You can come across performance issues when this directory doesn't have adequate disk space. For better performance, make sure that this directory is located on a local disk.	%DefaultDataDir%

Note

Restart the server for the changes to take Effect.

The Adaptive Job server can host several different services. Each service has the following properties:

Service Properties

Property	Description	Default Value
Maximum Concurrent Jobs	Specifies the number of concurrent independent processes (child processes) that the server allows. You can adjust the maximum number of jobs to meet your reporting environment. The default setting is acceptable for reporting scenarios. The setting for your reporting environment depends on your hardware configuration, database software, and reporting requirements.	The default value is 5.
Maximum Child Requests	Specifies the number of jobs the child will process before restarting.	The value is 100.
