Parameter Name

Meaning

Unit

Standard value

rdisp/wp_no_dia

Number of work processes of type dialog

Whole number (between 2 and 600)

2

rdisp/wp_no_btc

Number of work processes of type batch (background processing)

Whole number (between 0 and 600)

0

rdisp/wp_no_enq

Number of work processes of type enqueue (only on the enqueue instance >0)

Whole number (between 0 and 5)

0

rdisp/wp_no_vb

Number of work processes of type V1 update (time-critical)

Whole number (between 0 and 600)

0

rdisp/wp_no_vb2

Number of work processes of type V2 update (not time-critical)

Whole number (between 0 and 600)

0

rdisp/wp_no_spo

Number of work processes of type spool (print)

Whole number (between 0 and 600)

0

rdisp/wp_no_restricted*

Number of reserved work processes (see above)

Whole number (between 0 and 600)

0

rdisp/wp_max_no*

Maximum number of work processes including those created dynamically (see above)

Whole number between 2 and 600 (must be larger than the sum of all work process types), or DEFAULT

DEFAULT (Sum of all WPs + 2)

rdisp/dynamic_wp_check*

Activation of the check in the dispatcher, and if necessary of the starting of dynamic WPs (FALSE deactivates the capability of the server to create dynamic WPs)

Truth value

TRUE

rdisp/max_dynamic_wp_alive_time*

Lifespan of dynamic work processes: Dynamic work processes should be stopped once the bottleneck is removed. If you are not processing a request, the work processes are stopped after this time interval.

Seconds

300

rdisp/configurable_wp_no*

Number of configurable work processes for the Operation Mode Switching.

To enable the Dispatcher to resolve deadlocks automatically, at leastwpsForDeadlockHandlingwork processes are excluded from operation mode switching in the DEFAULT setting:

configurable_wp_no = wp_max_no - wpsForDeadlockHandling

whereby presently the kernel works with a fixedwpsForDeadlockHandling = 2 (only the kernel can change this setting).

If, as before, the number of processes is defined by the number of type-specific work processes (DIA, BTC, and so on), the sum of these processes is the number of configurable work processes. The maximum number of work processesrdisp/wp_max_no is increased accordingly bywpsForDeadlockHandling.

 Caution

This parameter should have the standard value DEFAULT. Only change the value in exceptional situations and after consulting SAP.

Whole number between 0 and 600, or DEFAULT

DEFAULT (maximum number of WPs minuswpsForDeadlockHandling, presently therefore: number of WPs minus 2)
