***ERROR: Size of shared memory pool 40 too small

================================================================

SOLUTIONS: (1) Locate shared memory segments outside of pool 40

with parameters like: ipc/shm_psize_<key> =0

SOLUTION: Increase size of shared memory pool 40

with parameter: ipc/shm_psize_40 =208000000

Kindly suggest

Kill some of Dialog work processes from OS level by using dpmon

And increase your Dialog processes based on your business requirement....seems you are running your system with very less dialog processes compare to your user accounts/requirement.

Hi Amber,NIck,Anil

I think you people didnt see the the process table properly

No Ty. Pid Status Cause Start Err Sem CPU Time Program Cl User Action Table

0 DIA 19557 Run no 0 4 0

4 DIA 19561 Run no 0 4 0

All the dialog process are in run state but as you can see not a single transaction is being executed. This was quite surprising for a newbie like me.

Not a single program/job is running still all processes are in run state.

My question has anybody encountered such issue?

What is reason behind this behaviour of processes?

SAP SCM version 5.00

DB is Maxdb 7.6

OS is linux

Kindly if possible answer my queries

Make sure database is up and running.

Then check log files of your work processes (dev_w*) for more information.

The first thing you need to know is what is triggering the processes.... so please post the contents of dev_w0

Hi Juan,

Well the trace files didnt provide any valuable hint ....but i will post it for you

Hello Joshi,

The problem seems to be with the shared memory.

Please clear shared memory and start all the services and start SAP again.

Clearly no transaction was running,it is only pure resource problem.

Thanks,

Hello Ameya, As the log says all the dialog processes are consumed. You might not be able to login at SAP.

can you please cancel some dialog process(old and invalid) and once deleted you can access thru SAP level and find out what might be the root cause of the issue. Like some parallel jobs are getting triggerred simultaneously and consuming all WP's.

Hope it helps.

PS : if you could provide your SAP, OS and DB details it will be very helpful. Thanks

Regards, Amber S

Hi,

If all the dialog process are full then you dont have any option to do.

Rather than wait for the activity which has occupied the dailog process to complete or kill the process if it is not in use.

Thanks

Anil
