How to find freespace in SAP system

[Former Member]

Hi all,

I want to increase SAP and Oracle buffer sizes.

1.How can I check all the process presently used memory and how much is free?

2.which processes mainly occufies RAM memory and which processes occufies extended or swap memory?

3.SAP buffer sizes+Oracle buffer sizes is equal to total memory or not?

how can I calculate total memory used ?

Hi,

u can use st06 to check the memory size in SAP level.

To know the exact values of the file system u can use the commands like]

df -P (for hp-ux and IBM-aix)

To know the memory usage of each work process u can use the "top" command in os level for unix and linux

Use transaction OS06 (and the detailed view)

This depends on the used operating system and the swap algorithm used...

The best case is, that no swap is used at all and everything resides in memory. The total memory usage is very dependent on how you use your system, how many users, what modules/applications you run etc.

Hi you can go to ST06 and go for table statistics where it will give you the fill levels of each table .

minimum threshold value is 95%.if they more than 95% add some table spaces and see the fill level.
