The first section of this screen provides general information for the buffer. The following information is provided:

Field Description
Name The buffer name.
SVC The Adabas SVC used for this buffer.
DB The Adabas database for which this buffer is used to provide optimization.
Dataspace The name of the dataspace when a dataspace cache is used.
Buffer Status Indicates whether or not the buffer is currently active.
Started The time at which the buffer was last started.
Ave Memory Val ... Session Number These fields are reserved for Software AG use.

The next section provides the buffer statistics. The following information is provided:

Field Description
Access Type

Attempts: the percentage of optimization attempts (opimization attempts divided by total number of commands).
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).
Excluded

Attempts: the number of commands which were excluded from optimization, and percentage (number of excluded commands divided by total number of commands).

Note:
For more information on excluded attempts, use PF6.

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).

Pressing PF6 from any of the buffer information screens displays the Excluded Command Analysis screen:

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.

The second section of this screen provides the following information:

Field Description
Updates The number of update commands processed for this database.
Over-reads

The number of read-aheads performed but not needed by the application, and the percentage of non-needed over-reads to the number of successful read-aheads. Non-needed over-reads represent overhead that may reduce the effectiveness of read-ahead optimization. In general, over-reads should not exceed 25% of read-ahead successes.

Status ... Nuc ID These fields are reserved for Software AG use.

The first section of this screen (Optimization Summary) provides optimization statistics for the file. This information is provided in the same format as that provided at the database level.

The second section of this screen provides the following information:

Field Description
Updates The number of update commands processed for this file.
Over-reads

The number of read-aheads performed but not needed by the application, and the percentage of non-needed over-reads to the number of successful read-aheads. Non-needed over-reads represent overhead that may reduce the effectiveness of read-ahead optimization. In general, over-reads should not exceed 25% of read-ahead successes.

Set Limit ... Set Concurrency The current settings for various file optimization parameters. For a description of each parameter, see the section Adabas Fastpath Parameters.
Status ... Addr These fields are reserved for Software AG use.

Pressing PF9 invokes the second File Details screen. This screen shows whether or not optimization has been defined for the Adabas command/descriptor pairs which are used to access the file.

The following information is provided:

Field Description
C Option code. The following options are available:

d: display detailed set information
f: display full set list

CC De The Adabas command/descriptor pair for which information is provided.
Sets The number of sets that have been added together to make the summary.
Number of Items The number of items (records) in use at the present time, the peak number of items used, and the number of times items in the set were used for optimization.
Memory The memory in use to hold the data in the sets (in k) and the peak memory usage for all 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.

File Set List

If the option code f is selected for a command/descriptor pair on the File Set Summary screen, the Set Summary screen will be displayed.

This screen contains an activity summary for each direct access set used by the selected command/descriptor pair.

Field Description
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.
Items ...

Optimized: the number of successful optimizations from data records in the set.
Added: the number of times a data record was inserted into the set.
Collisions: the number of times a set was inaccessible because concurrency for the set was exhausted.
Current: the number of data records currently in the set.
Peak: the highest number of data records which have been in the set.
Free: the number of free data item areas currently available.
Removed: the number of data records which have been removed from the set.
RLU: the number of times an individual data record was removed from the set as a result of a database modification command (for example, update, insert, delete).
Overwrites: the number of times a new data record was inserted by overwriting an existing record because no free area was available.
Set Resets: the number of times a complete set was emptied.

Memory The memory in use to hold the data in the sets (in k) and the peak memory usage for all sets.
Status ... Reject These fields are reserved for Software AG use.
