|         Activating Background Processing                             |

------------------------------------------------------------------------

| By default, background processing is inactivated. To enable backgroun|

| processing, you must set the %%rdisp/myname%% , %%rdisp/wp_btc_no%%  |

| and %%rdisp/btctime%% system parameters. You can activate background |

| processing in any number of servers.  To configure a server to proces|

| background jobs, set the background processing parameters in the     |

| system profile as follows:                                           |

| %%rdisp/myname%%                                                     |

| 1.  Enter a unique name for the application server.                  |

|     The name is user-definable. It does not need to correspond to the|

|     R/3 System or host system name.                                  |

| 2.  Set this parameter in the background server's private profile.i  |

| %%rdisp/btctime%%                                                    |

| 1.  Enter the interval in seconds at which the background            |

|     time-based scheduler should routinely be started.                |

|     The scheduler starts all eligible jobs whenever it is started.   |

| 2.  Set this parameter in the background server's private profile.   |

|     If this parameter is set to the default value of 0 in the default|

|     profile, the scheduler will not routinely be started. If the     |

|     parameter is set to 0 in the application processor, no background|

|     processing will be performed.  The following parameters are      |

|     overridden by operation mode definitions:                        |

| %%rdisp/wp_no_btc%%                                                  |

| 1.  Enter the number of work processes that are to be used only for  |

|     background processing. If this parameter is set to 0, no         |

|     background processing will be performed in the application server|

|     Therefore, enter at least 1.                                     |

| 2.  Set this parameter in the background server's private profile.   |

|     Leave this parameter set to 0 in the default profile.            |

| %%rdisp/wp_no_dia%%                                                  |

| 1.  Enter the number of work processes that are to be used for       |

|     processing dialog requests.  The number must be at least 1. The  |

|     background scheduler requires a dialog work process in which to  |

|     run.                                                             |

| 2.  Set this parameter in the background server's private profile.   |

|     Specifying the Event-Based Scheduler Only one event-based        |

|     scheduler can run at a time. You must define where this scheduler|

|     runs.  To define the instance, on which the event-based scheduler|

|     runs, use the system parameter rdisp/btcname                     |

| Reserving Work Processes For Class A Jobs                            |

| When defining a background processing instance, you can reserve work |

| processes exclusively for processing jobs of class A.  By reserving  |

| at least one work process for such jobs, you ensure that important   |

| class A jobs cannot be blocked by less important jobs.  If the number|

| of class A work processes in an instance is the same as the total    |

| number of work processes, then only jobs of class A can be processed.|

| All other jobs are blocked.                                          |
