This section describes how to obtain and use the buffer statistics available for the active Adabas Fastpath buffer.
Active Fastpath buffers can be monitored and controlled by selecting
option code 2 on the Online Services main menu or by
entering the command 2 on the
command line.
The Session Monitoring menu is then displayed.

The first section of this screen (Optimization Summary) provides optimization statistics for this database. This information is provided in the same format as that provided at the buffer level (see section Buffer Information). The statistics shown at the database level are exclusively for commands that are eligible for optimization. The excluded count therefore differs from the buffer level count.

| Memory |
In use: The amount of memory productively being used by these sets. Each set may also have extra memory allocated to it for the purposes of set growth, so the sum of the "In use" memory for all the sets in a file will not be the same as the "Set usage (k)" from the summary file information screen. Peak: The HWM of all memory that has ever been allocated for use by these sets |
| Growth Mode | Fastpath regularly assesses the worthiness of all direct-access sets as being high, medium or low. Based upon this assessment Fastpath is likely to award more memory to sets assessed highly, when there is memory available, and to remove memory from the less worthy sets. The regular reassessment means the assessment of a set will quickly change according to current system activity thereby making sure the most appropriate optimization levels are maintained at all times. |
