Performance problem

[Former Member]

Hello solman experts,

we are facing on our Solution manager with the problem that sporadically all the dialog processes are in state "on hold" (see the picture bellow).

We use mainly CCMS and MAI parallel for several systems.

Can something be done against this problem?

Thank you!

Hi Alex,

Could you share dev_rfc0 log file for analysis ?

Addition to it kindly follow solution from SAP Note  726148 - SAPLARFC occupies all work processes, RFC cascade & check again.

Hope this will help you.

Regards,

Gaurav

Hi ,

Check in your RZ12  ( parallel generator group )

Check SMQR and SMQS and defne the number of maximum connections to ur solution manager

In RZ12 we have 2 logon groups:

562

DEFAULT

Any suggestions?

What do you mean with SMQR and SMQS?

[manumohandas82]

Hi Alex ,

You need to reduce both  ( ie 562 and DEfault ) . If you double click You can reduce the "Max Number of Logons" , "Max Number of work process used " and inerease minmum number of free wp

In txn SMQS you can define a seperate queue to Solution mansger or other and restrict the amount of maximum connections

In managed system configuration if you would have used load balancing you could have restricted to any one server ( if you have multiple application server )

Thanks ,

Hello,

many thanks!

Enclosed the current settings of RFC Server groups settings of both groups (DEFAULT and 562) which are identical.

How would you like to recommend to change these settings?

Thank you!

the reason is the WPs are waiting for RFC Work process is waiting for the response from an RFC call. Check or attach for dev_rfc<x> (example dev_rfc0) in the work directory (usr\sap\<SID>\instance\work).

Hello Sunil/hello all,

many thanks!

Is there any possibilty to restrict the amount of free dialog work processes in order to leave at least 2 dialog work processes independent of RFC calls?

Thanks!

check the parameter rdisp/rfc_min_wait_dia_wp documentation in RZ11.

[Former Member]

The parameter rdisp/rfc_min_wait_dia_wp is set to 2.

Unfortunately if you see the enclosed picture above it does apply....

Any additional suggestions?
