Total AI writes — The total number of writes to the AI file.
AIW AI writes — The number of AI writes performed by the after-image writer (AIW). This is a subset of the total AI writes.
Records written — The number of records (notes) written to the AI file.
Bytes written — The amount of AI data written to the AI file, in bytes.
Busy buffer waits — The number of times a process had to wait because a buffer was held.
Buffer not avail — The total number of times a process had to wait because a buffer was not available.
Partial writes — The number of writes to the AI file made before the AI buffer is full. This might happen if:
The Delayed BI File Write (-Mf) parameter timer expired before the buffer was filled
An APW attempts to write a block whose changes are recorded in an AI buffer that has not been written
Log force waits — The number of waiting-for-commit records to be written to disk.
