The following table shows which counters are included in the Memory resources.
Table 2- 10 Memory resources
| Counter | Description |
|---|
| Private Mode | Private mode conditions should not occur. When private mode conditions occur, the SAP application server's shared memory is insufficient to meet the demands of the application, and the following occurs: - Memory for the work process must be "locked down" for the duration of the application request.
- Contents of memory for the work process, such as context area, must be restricted to the application and cannot be shared with other applications.
- Overhead associated with unnecessary memory management occurs.
|
| Extended Memory | To determine memory shortage impact on an application's response time, do the following: - Check the importance of application time as a percentage to total response time.
- If application time is high, determine its relationship to memory usage.
- Use the Application Time section to determine if application time is attributed to memory management or application processing. If application time is attributed primarily to load time, private mode conditions may be the cause of poor response time.
- SAP shared memory may be insufficient for this particular application or it may be an issue for other applications as well.
- Use the Extended Memory counter to determine shared memory requirements for this application.
