how to use servergroup?

[Former Member]

Hi all,

I have seen how to create a servergroup in Tx RZ12 joining servers into a group and leaving free Workprocesses (for other users).

Now I want to execute a program in parallel using this server group and I do not know how.

(How) Can I use a servergroup executing a standard program? and/or using a self;written program?

I would appreciate if someone could geive me examples/explanation.

Thanks in advance

check this FM

* group in which parallel processing is to take place.
* Could be used to optimize sizing of work packets
* work / WP_AVAILABLE).

Hi Prabhu,

I think this fm is used to check the free Workprocesses of the servergroup.

My question was how can I use servergroups for

a) standard reports/programs

b) customer reports/programs

with reference to a):

is there an option in an standard program where I can select the servergroup to be used?

what have I to implement in my programs if I want them to be executed by a servergroup?

Perhaps someone can explain this to me???

Thanks,

Hi Thomas,

In fact inside reports/programs it is not possible, but to run these programs on a specific server or servergroup, you must create a batchtask (via transaction SM36) .

Within the transaction SM36 you can supply the server or servergroup in the field Exec. Target.

The program/report will run there if sufficient BTC processes are available.

The solution of Prabhu works in combination with RFC enabled function modules and BAPI's.

You could make an RFC enabled function module of your own that will SUBMIT the report/program in question. Then from another program (or function module) call your RFC enabled function module with a destination SERVERGROUP or RFC DESTINATION or SERVER.

View the function module SRM_RFC_SUBMIT_REPORT (on a CRM or SRM system).

Hi Rob,

that was the info I was looking for.

Thanks,
