Lot of swaps Occuring

[Former Member]

Hi Experts

We have ECC 6.0 which was upgraded from 4.6c. Everthing went on smooth, except for a major performance issue. Initially when i came into this project i tried a lot of steps like increasing the swap space and stuff where the hit ratio was set due to the change.

Now the issue is that there a lot of swaps occuring and i really do not know where to go from here.i already increased the swap space by around 200MB. Please do advise me on what to do. Generally wht is the best procedure to follow when there are a lot of swaps occuring.

Thanks in advance.

Recommedn you to configure at least 20 gigabytes of swap space in 64-bit systems. (Plus approx. 10 GB for every additional 64-bit instance on the same computer).

Go through these notes for the recommendations

Note 146289 - Parameter Recommendations for 64-Bit SAP Kernel

Hello Bharani,

Kindly increase the swap space to 20 GB from O.S. level.

It will solve your issue.

Also check the virtual memeory.

Provide the points if solution helps your issue.
