The following information is provided:
| Field | Description |
|---|---|
| Access | Attempts: the percentage of optimization attempts (optimization attempts divided by total number of commands). |
| Type | Successes: the percentage of successful optimization attempts (successful optimization attempts divided by number of optimization attempts). |
| Read-Ahead | Attempts: the number of read-ahead optimization attempts, and the attempt percentage (read-ahead optimization attempts divided by total number of commands). Successes: the number of successful read-ahead optimization attempts, and the percentage of successful attempts (successful read-ahead optimization attempts divided by read-ahead optimization attempts). |
| Direct | Attempts: the number of direct access optimization attempts, and the attempt percentage (direct access optimization attempts divided by total number of commands). Successes: the number of successful direct access optimization attempts, and the percentage of successful attempts (successful direct access optimization attempts divided by direct access optimization attempts). |
| RCs | Attempts is always equal to successes. This is the number of optimized RCs that immediately followed a direct access command (without any intervening "next" commands). |
| Others | Attempts: the number of commands which were
excluded from optimization, and percentage (number of these excluded commands
divided by total number of commands).
Note: |
| Total | Attempts: the total number of commands encountered by Adabas Fastpath. Successes: the total number of successful optimization attempts, and the percentage of successful attempts (successful optimization attempts divided by total number of commands). |
