1  –  group_commits_field

    This field displays the number of group commit operations
    performed by the ALS process. Dividing the number of transactions
    by the number of groups gives the average group size (the inverse
    of the transaction average display.)

2  –  quick_flushes_field

    This field gives the number of times users requested their .aij
    records be flushed to the .aij file and those records had already
    been flushed by the cooperative actions of another user (group
    commit).

3  –  ARB pool searches field

    This field gives the number of times the global after-image
    journal request block pool was searched. AIJ records are globally
    buffered using ARBs.

4  –  ____pre_allocation_field_

    This field gives the number of ARBs that are able to be pre-
    allocated, resulting in reduced transaction commit or rollback
    processing (increased throughput).

5  –  ____pool_empty_field_

    This field gives the number of times that the global after-image
    journal request block (ARB) pool was found to be empty. In this
    event, the active user must force a write operation to the after-
    image journal file to free an ARB.

6  –  cancel:_preemptive_field

    This field displays the number of times the background group-
    commit operation was canceled because there was no additional
    data to be formatted.

7  –  IO free format field

    This field displays the number of times the foreground group-
    commit operation was canceled because there was no additional
    data to be formatted.

8  –  submit:_watchdog_field

    This field displays the number of times the ALS process attempted
    to perform a group-commit operation in anticipation of new work
    but found none.

9  –  ___io_completion_field

    This field displays the number of times the group-commit
    formatting was completed because the pending asynchronous I/O
    operation for the previous group-commit operation completed.

10  –  ___cache_overflows_field

    This field displays the number of times the 64-block .aij cache
    has overflowed.

11  –  ___cache_satisfied_field

    This field displays the number of times the group-commit
    formatting was completed because the cache-size constraints have
    been reached.

12  –  ___control_record_field

    This field displays the number of times the group-commit
    formatting was completed because of encountering a control
    record for which a process was waiting (and there was no I/O
    in progress).

13  –  DBR recovery field

    This field displays the number of times the group-commit
    formatting was completed because the current process is DBR and
    the database is frozen.
