How do I prevent all dialog processes in SM50 from being occupied?

[former_member211576]

Hi experts,

  I have set rdisp/rfc_min_wait_dia_wp = 4 and I still saw all dialog processes got occupied.

(PS: This screenshot is captured after a few minutes). Anyway, how do I prevent all dialog processes in SM50 from being occupied?

Should I increase rdisp/rfc_min_wait_dia_wp ( = 4 now ) and rdisp/wp_no_dia ( = 18 now ) to a higher value?

Hi,

Parameter is working absolutely fine, you have more than 4 DIA WPs in waiting status (not occupied).

Then what is the concern?

Parameter is to prevent the RFC logins, so you kept only 4 to be dedicated for Dialog operations.

If you find all other are occupied, then you should look at parallelism configuration and increasing the total number of DIA work processes.

Hi Gaurav & Nick,

   If I understand correctly, there are 4 dialog processes running and 14 RFC running at the same time.

If I want to resolve this problem, I need to reduce paralellism of RFCs and increase dialog work processes, right? Here is my new configuration. Any thoughts?

new parameters:

rdisp/wp_no_dia = 20

rdisp/rfc_min_wait_dia_wp = 10

rdisp/rfc_check = 3

old parameters in profile:

rdisp/wp_no_dia = 18

rdisp/wp_no_btc = 13

rdisp/wp_no_enq = 0

rdisp/wp_no_spo = 2

rdisp/wp_no_vb = 5

rdisp/wp_no_vb2 = 2

rdisp/rfc_min_wait_dia_wp = 4

rdisp/rfc_check = DEFAULT  (DEFAULT is 2, ASYNC and SYNC RFC)

Hello Dennis,

please have a look at the recommendations in the note:

726148 - SAPLARFC occupies all work processes, RFC cascade

Current parameters in profile:

rdisp/wp_no_dia = 18

rdisp/wp_no_btc = 13

rdisp/wp_no_enq = 0

rdisp/wp_no_spo = 2

rdisp/wp_no_vb = 5

rdisp/wp_no_vb2 = 2

rdisp/rfc_min_wait_dia_wp = 4

rdisp/rfc_check = DEFAULT  (DEFAULT is 2, ASYNC and SYNC RFC)

By the way, what is the difference between 2 and 3? They both include ASYNC and SYNC RFC.

Hi Lee,

As per your requirements you can increase the value for parameter rdisp/rfc_min_wait_dia_wp upto 6.For ref kindly follow SAP doc at  http://help.sap.com/saphelp_nw70/helpdata/en/83/b7f2c1a90e2f4dbcc162388f0227dc/content.htm
