value for parameter cache_size

hello frindes,

i have a dell machine (1 proc) with 4 GB RAM and Suse Linux Enterprise Server 10 SP2 in 64 bit with MaxDB Software 7.6.03 in 64 bit. I want to install 2 (central-) instances (1. test and 2. PRD)in NUC ECC6.0 Standard only ABAP Stack.

Only max. 2 SAP-User should be work with this 2 instances. 3 DIA and 1 BTC of workprocesses per instances should be enough.

how much do I choose the parameter cache_size? i'm during the installation of the first instance an I chosse for the first test instance 600 MB. about a third from 2 GB per instance.

is this correctly?

many thanks for ideas ...

    you have to make sure, the CACHE_SIZE and all the buffers and parameters you configure later in ST02 will not exceed the total available memory. Once the machine starts swapping, everything will be very slow.

    So yes - 600 MB for both database instances is fine.
