shmfs_size and SAP

[Carles Viaplana]

Hello,

We have linux 9 installed in ProLiant with SAP dialog instance running on.

We started SAP but when we checked status we found this message:

System imposed size of of shared mem segments: 107341824, required: 1073741924.

Can I increase this value without any issue?
Should I restart server?
Is there any limit for this parameter?

Thanks in advance for your help.
Regards,

Carles

SuSE 9 (64bit) SAP R3 server right?....

You can set this in /etc/sysconfig/kernel
The variable is: SHMFS_SIZE="NUMBER"

Note that you can add a "G" after the number to make it as GB.

Ensure you have installed RPMs saplocales & suse-sapinit then you may have to massage/combine /etc/sysctl.conf, /etc/sysctl.conf.sap
