Dear All,
I am trying to re-configure ASE memory on our SAP servers, most of the servers has shared memory values set to unlimited.
Current databases were configured with default memory usage, now i am planning to increase current size and configure data cache to use 50 to 55% of the physical memory.
Our production system has 64 GB of memory , if i use half of it for database then it will be 32 GB since kernel parameters are already set to unlimited , shall i increase max memory and then followed by data cache and wash size ? Currently only 16k I/O buffer pool is configured for a smaller size, i would like to configure 128k I/O buffer pool with at least 10 GB.
Is it a good approach to start with ? I am not a Sybase expert , please help me with correct values
Please see current settings below
kernel.shmmax = 9223372036854775807
kernel.sem = 1250 256000 100 8192
kernel.shmall = 1152921504606846720
vm.max_map_count = 2000000
Max Memory
Configured Value: 1792000 memory pages(2k)
Default Value: 139264 memory pages(2k)
Run Value: 1792000 memory pages(2k)
Value Range: 139264:2147483647
