Measures reported by AsAbapMemTest

This test monitors the basic functions of the SAP Memory Management System and advises on how best to configure the system depending upon the platform used, the available resources, etc. It also sheds light on the hardware and operating system usage.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Ext_mem_actual_use The actual usage of extended memory. Percent  
Ext_mem_attached The percentage of extended memory in user contexts that is active in WPs now. Percent  
Ext_mem_slot_actual_use The percentage of extended memory slots actually used. Percent  
Ext_mem_slot_total The number of extended memory slots. Number  
Ext_mem_total Indicates the total size of the extended memory. MB  
Heap_mem_actual_use The percentage of heap memory actually used. Percent Heap memory is a local memory assigned for the work process in SAP. Heap memory contains user contexts. Typically, if a dialog work process fully utilizes the extended memory, it starts . Once the heap memory is assigned to a work process, the work process will switch to the PRIV mode. This means that the work process is reserved for processing the current user context until the context releases the work process again when the request has ended.

If this measure reports a non-zero value, it implies that heap memory has been used – i.e., one/more work processes are in the PRIV mode.

For best performance, not too many dialog work processes should be in the PRIV mode simultaneously. So, if this measure reports a high value, then check the
Heap_mem_total The total size of heap memory (private memory). MB  
Private_work_procs The number of restarted private work processes. Number  
Dlg_work_procs_restart The number of restarted dialog processes. Number  
Non_dlg_work_procs_restart The number of non-dialog processes restarted. Number
