Hi,

This means that your buffers are hit badly, generally there are always swaps in an SAP system, and these keep increasing day by day if the instance is not restarted recently, an instance restart will clear the red buffer entries in ST02.

But to reduce the swaps, increasing (or rather say optimizing) buffer memory is required.

SAP application servers are important users of swap space. If the swap space on a computer is used up, serious system problems occur as a result. Therefore, you must monitor swap space usage.

be carefull, swap is not equally swap... it might be also quality of buffer

searching "ST02 swap" you will find some interesting threads

HI,

double click on swaps with red than click on current parameter you get the relavant parameter value for that

you can increase this parameter value using RZ10 to avoide/reduce swaps

be carefull while changing parameter, find the relavant sap note for memory management for your OS/DB
