Swap Space Requirements
Use
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.
64-bit technology means that the address space can now be used more generously. This minimizes maintenance requirements and the problems associated with memory management, since the size of the buffers and other areas in the shared memory can be increased considerably.
As a result, there is no risk of program crashes due to memory bottlenecks and no need for complex “parameter tuning”.
Monitoring Swap Space Usage
To monitor swap space, you can use either the monitoring tool for host operating systems or the system monitor from the SAP Computing Center Management System (CCMS). The CCMS Alert Monitor, which is available via the system monitor, issues warning messages if the swap space usage exceeds a preset limit. You can also display the present usage.
