Memory distribution recommendations

[erick-acosta]

Hi,

We are installing Solution Manager 7.0 with Oracle 10.2 and Windows 2003 (all of them 64 bits). The total memory available is 12GB.

What do you recommend for distributing between SAP (abap/java stack) and Oracle?

In SAP note 88416 (Zero memory administration) it says that as a rule of thumb, use SAP/DB = 70/30 and set the parameter PHYS_MEMSIZE to approximately 70% of the installed main memory.

It gives a 8.4/3.6 GB distribution.

Otherwise, SAP note 723909 says that for 64 bits it's recommended 2048MB for java.

So, I'm not sure if the memory for SAP includes both stacks abap and java... I mean, do I have to set parameter PHYS_MEMSIZE to 70% minus the memory dedicated to Java? (8.4 - 2 = 6.4)

How would you distribute 12GB in this scenario?

Any help will be appreciated.

Hi Erick,

>do I have to set parameter PHYS_MEMSIZE to 70% minus the memory dedicated to Java? (8.4 - 2 = 6.4)

Yes, as Note was written before the Java stack.

Hi Erick,

I agree with Mark's understanding your scenario.

Even i was in a dilemma regarding this earlier, but did some search and found

the below input.

In the maximum usage of Java stacks, it will consume the memory of 2GB(which we are assigning to heap_size), or else there won't be any problem.

So I would suggest you to stick with your memory related recommendations.

Please let us know if you find any other suggestion regarding this in future.

Thank you,
