***ERROR: Maximum shared memory segment size exceeded

[former_member229542]

Hi Guys,

Im installing a BusinessObjects Application and as part of ABAP server configurations it required to increase

abap/buffersize to 2GB; actually its set to 300,000 KB

After checking with SAPPFPAR im getting the following message

Does this require increase Shared Windows Memory cap?

Should add /PAE to boot.ini according as per http://support.microsoft.com/kb/q283037/

Actual Systems Specs are:

Windows Server 2003 R2

Enterprise x64 Edition

6GB RAM

Thanks!

Hello,

/PAE is only for 32 bit Windows

Check your memory parameters with

88416 zero admin memory

Thanks

That note helped to determine the proper values.

Hi,

this 'shared memory' message is a false interpretation of the sappfpar

program which it is known to occur on 64-bit platform servers.

It is OK to ignore it.

On 64-bit platform systems the shared memory size is currently limited

only by the hardware resources a machine can provide.

Naveen.

Hi Naveen, thanks for your input, but sadly SAP does not start after increasing that parameter.

All WPs are halted, and the ABAP disp+work just ends.

Regards!

Hi Martin,

There should be no address space limitation on 64bit OS.

May i know where's the database for BO Installed? is it on the same host? if yes, how much memory assign?

Cheers,
