hello,

Main note for memory on Windows is

88416 Memory management Zero administration

Check parameters as in note

Normally setting PHYS_MEMSIZE to 70% of physical memory is the recommendation

Hi Edy,

I may not  you exact answer , but can provide some useful information.

As deepak addressed , pl refer to sap note 117650 for automated db check. end of the notes script is provided for for your db release. this can be done now also before upgrading the RAM

Check you current repsonse times, appl servers , workload and concurrent users currently working including the time taken currently for Background jobs to complete

Check sap notes on Sun solaris tuning,

Tune your application  profiles on central and dialog instances based on available memory

Check sap notes for oracle as mentioned above , also refer to 830576, apply oracle bundle patches.identify fix_controls, events and __ (underscore) parameters and set as required

For DB  I would suggest look in to ( db_cache_size, pga_aggregate_target, shared_pool_size etc)

refer to updated Early watch alert for more recommondations

perform kernel upgrade

all above are documented in sap notes very precisely.

Identify the pain areas of your transactions of performance and you book technical performance optimization with sap support as you could get more help and recommondations.

thanks,

rahul

Hi Edy,

For Oracle database refer SAP note

1171650

Automated Oracle DB parameter check

You may run the script attached to this note based on your Oracle version 10g or 11g.

This script will provide necessary guidance on what parameters needs to be set and with what value.
