Max number of dialog processes on app servers

[Former Member]

Is there a formula for max number of dialogue process. I am running a mix environment but all unix.

And what about background processes?

Thanks

Hi,

Finding the right mix of different types of processes is a tuning process that has to be done progressively while learning the kind of load YOUR system is experimenting.

You begin with a general setting and then adjust it observing the load.

Hi,

The basic thumb rules for work processes are:

1) Minimum number of Dialog processes = 2

2) Minimum number of Background processes = 2

3) Minimum number of Update processes = 1

4) Minimum number of Spool processes = 1

5) Minimum number of Enqueue processes = 1

6) Maximum number of work processes allowed in an instance = 99

7) Number of Dialog work proceeses >= Sum of all other work processes in the landscape

Hope this is helpful. Please award points if helpful.

Thanks

Hi Mike,

The maximum number of work processes depends on several preconditions: SAP-internal resources, operating-system-specific restrictions, the representation of the work process number .

The most important preconditions for a high number of work processes are:

as of Release 4.6x and higher: 240 (with kernel patch as of approx. June

2004)

Please check OSS note 9942 for more details
