Excluded Command Summary

Adabas Fastpath Online Services can be used to display commands excluded from optimization by exclusion category.


Excluded: Reasons

Unsuitable command type
Explanation

Command code cannot be optimized.

Action

None.


Disqualified
Explanation

Commands ignored because the database/file/command code or descriptor has not been defined for optimization.

Action

None required or define a new database/file parameter, or remove command code/exclusion from file definitions. Define optimization for these if you believe there is sufficient benefit.


Optimization was disabled
Explanation

The most common reason is that a database/file has been disconnected, or a job is in the process of termination. It is also possible that a job has been unable to connect or the buffer is down.

Action

Use SYSAFP to check whether a database or file is not optimizing. Consider increase to the Maximum Jobs count in the Buffer parameters.


Multi-fetch was already set
Explanation

Read-ahead optimization was not possible because the command was already set to perform prefetch or multifetch.

Action

Consider if Fastpaths’ totally dynamic read-ahead is more flexible than specific programming.


Command details exceed Set-id limit
Explanation

Commands were ignored for direct access optimization because the Set ID length exceeded the limit.

Action

Review the buffer and file parameters set ID length limit and increase if required.


Record Buffer exceeds the limit
Explanation

Commands that could not be optimized because the Adabas record buffer length exceeds the limit.

Action

Review the buffer and file parameter RB length limit and increase if required.
