Hi Sriram,
Thanks for your reply.
1. Each DI physical server level you have to define the memory parameters.
Yes, we have copied the entire parameters values as same as DI 1 & kept in DI 2.
My question is here, whether we need to share/divide all the parameters set accordingly in instance profile or not ??? If you require i can attach all parameters which has been set in DI 1 & DI 2.
2. You have to define in the instance profile parameters and as per the SAP Note 88416 base reference of the initial memory and buffer parameters, in a month you have to review the memory parameters,
Please check the below link Memory parameters for SAP on 64 Bit Windows screenshot, which describes to add phys_memsize, need to understand how to add that parameter & calculation whether it should be in Default or Instance profile, where other parameters values will be calculated automatically.
