All the parameter what you mentioned is for Oracle. But you have to increase your PHYS_MEM in sap profile parameter according to it. If it is a Netweaver system, it is zero memory management and buffers will tune auto. But still you have to keep a track on ST02 for any swaps appearing.

Subject: SAP - Kernel Parameter Update
Best Friends
Recently added new hardware to a production server, before I had:
06 cpu
24 Gb Mem
Now you have:
08 cpu
32Gb Mem
After that, evaluate SGA Delk increase server area was very small, the area now has 8GB SGA
The parameters to increase in this activity increased SGA were:
Before Now
sga_max_size 03Gb 08Gb
db_cache_size 02Gb 04Gb
SHARED_POOL_SIZE 816Mb 2.4Gb
shared_pool_reserved_size 84Mb 245 Mb
What I'm not clear is the following,:
After increasing CPU and memory on the server and then adjust these parameters of the SGA,
I have to adjust or increase any kernel parameter value??
That's the point, I know the parameters needed depending on the SAP installation should have some defaults.
But here, after increasing CPU and memory, there is also some connection to increase certain parameters at the kernel level?
I do not know.
So my consuls, if I increase some kernel parameters.
In my scenario is HPUX 11.23
Thank you for your attention |
