Specifying servers for scheduling

You can specify the default job servers that Crystal Enterprise will use to run an object, and to schedule and process instances. When specifying your servers, you have three options:

• Use the first available server.
• Use the servers that belong to a selected group first (and, if the servers from that group aren't available, use any available server).
• Use only servers that belong to a specific group.

By selecting a particular server or server group, you can balance the load of your scheduling, because specific objects can be processed by specific job servers. You must first create server groups by using the Server Groups management area in the CMC, before you can select servers that belong to a selected group. You can also set the maximum number of jobs that a job server will accept. For more information, see Modifying performance settings for Job Servers.

Also, you can balance the load of your scheduling, because specific objects can be processed by specific job servers. You must first create server groups by using the Server Groups management area in the CMC, before you can select servers that belong to a selected group. You can also set the maximum number of jobs that a job server will accept. For more information, see Modifying performance settings for Job Servers.

Note:    

• If you choose the "Use the first available server" option, the Crystal Management Server (CMS) will check the job servers to see which one has the lowest load. The CMS does this by checking the percentage of the maximum load on each job server. If all of the job servers have the same load percentage, then the CMS will randomly pick a job server.
• If you are scheduling a program object that requires access to files stored locally on a Program Job Server, but you have multiple Program Job Servers, you must specify which server to use to run the program.
• See Specifying servers for viewing and modification for information on specifying the servers used to view or modify an object.

To specify the servers to use for an object

1. In the Objects management area of the CMC, select an object by clicking its link.
2. Click the Process tab.

   

3. In the "Default Servers To Use For Scheduling" area, choose from one of the three options:
   • Use the first available server

     Crystal Enterprise will use the server that has the most resources free at the time of scheduling.

   • Give preference to servers belonging to the selected group

     Select a server group from the list. This option will attempt to process the object from the servers that are found within your server group. If the specified servers are not available, then the object will be processed on the next available server.

   • Only use servers belonging to the selected group

     This option ensures that Crystal Enterprise will only use the specified servers that are found within the selected server group. If all of the servers in the server group are unavailable, then the object will not be processed.

4. Click Update.
5. In the "Default Servers To Use For Viewing" area, repeat the activities from steps 3 and 4.

   Note:    "Default Servers To Use For Viewing" applies only to report objects.
