The job scheduler can be hosted by either an application server or a cluster. Only a single application server or cluster can host the job scheduler at any given time.
<br/>
<br/>
<strong>An application server host </strong> <br/>
<dl>
<li>
is recommended for test environments
</li>
<li>
can utilize the default Cloudscape (Derby) v10/1.x database
</li>
</dl>
<strong>A cluster host</strong>
<dl>
<li>
is recommended for production environments or any environment in which a scalable, highly available job scheduler is required.
</li>
<li>
requires a cluster capable database
</li>
</dl>
To host the job scheduler on an application server using the default Derby database, skip to

To define the database tables that store job information, use a Data Definition Language (DDL) file provided during the installation of Compute Grid. The files are located the <code><WAS_INSTALL_ROOT>/longRunning</code> directory.
<dl>
<li>DB2 - <code>CreateLRSCHEDTablesDB2.ddl;</code></li>
<li>Derby - <code>CreateLRSCHEDTablesDerby.ddl</code>;</li>

-
Click <strong>Save</strong> in the message at the top of the console panel to update the master configuration.
-
Start or restart the application server or the cluster member defined in the previous step. A dynamic cluster member application server's name is in the form:
<br/>
<br/>
{dynamic_cluster_name}_{node_name}
-
After completing the previous steps, the job scheduler is configured and ready to accept Compute Grid jobs..
