The resource utilization displays provide a comprehensive overview of Adabas operation.
Each of the resource utilization options contain a refresh capability (PF4) that allows you to refresh the displayed values, a convenience for long-term monitoring of Adabas system functions.
This document covers the following topics:
Overall Command Usage (option "C") displays the total and average execution time of each Adabas command type issued during the current session and processed by the Adabas nucleus, and the total of all Adabas commands issued.

High Water Marks (option "H") displays the maximum percent of use of selected pools and queues in the current session, and the date and time when the high point was reached.
Values are displayed for the user, command, and hold queues; the ISN list and sequential command tables; the format and work pools; and the attached buffers (NAB).
These values are a good starting point when looking for a problem with limited buffer, pool, or queue space, or if you are looking for unused storage resources.

In an Adabas cluster environment, the file may be locked for exclusive use by another cluster nucleus. If this is the case and the file is in the nucleus file status table, the Locking NucID column for the file shows the ID of the nucleus that has exclusive control.
The Access count / Update count fields display the number of access or update users, respectively, that refer to the specified file in their user queue elements (UQEs). These users either have specified the file in an OP command with "R"-option or are using the file in an as yet incomplete transaction.
A State field indicates when the file is used for access only or for access and update. The State field indicates to what extent a nucleus can use a file on its own. If the requested use exceeds the given state, the nucleus must first communicate with the other nuclei in the cluster in order to upgrade the state.
Protection Log (PLOG) Status (option "P") displays the status of dual protection logs, if used.
The equivalent direct command is
