Memory(RAM) Constraint for 32 bit BO 3.1

[vedpal_yadav]

Hi

Sorry for the duplicacy. I have seen this topic earlier as well in forums but I am still having some confusion and looking for some definite answers.

BO 3.1 is a 32 bit application which could be installed either on 32 or 64 bit OS. There is a memory cap of 4 GB for 32 bit applications by design.

So what do we mean by 4 GB cap for BO 3.1 Server ?

Let's consider this scenario below:-

1.  BO 3.1 Server installed on a single core box on 32 bit or 64 bit OS.

-So in the above scenario on 32 bit OS 4 GB RAM is the max limit that can be installed. Is it true ?

-In second case on 64 bit OS the RAM limit can go up depending on the OS version. So can we utilize the RAM above 4 GB by creating multiple BO Processes or Services. 2 GB is the cap for BO processes. Correct ?

So my question is -  For 32 bit applications(BO 3.1) the max memory cap is per machine or core/processor or BO Processes. If we don't consider clustering then how much can we scale up on a single box in terms of BO processes if  we have a multiple core machine with ample amount of RAM available.

Can someone guide me to some documentation related to this.

Thanks in advance,

Regards,

Vedpal

Hey,

please find your answers:

1. True

2. True

The 2 GB Size Limit is per BO Services (This is not a limitation of the SAP BO Application. This is a limitation of the amount of RAM a process can utilize on a 32 Bit OS).

To overcome this you can create multiple Services (For Example Web Intelligence Processing Server) on one Machine or you can seperate them over nodes within a Cluster.
