Number of times that each engine completed I/O. “% of total” reports the percentage of times each engine completed I/Os as a percentage of the total number of I/Os completed by all Adaptive Server engines combined.
In threaded mode, Adaptive Server does not print the completed disk I/Os on a per-engine basis. Instead, it prints a server-wide summary:
Disk I/O Management ------------------- Max Outstanding I/Os per sec per xact count % of total ------------------------- ------------ ------------ ---------- --------- Server n/a n/a 17 n/a Engine 0 n/a n/a 5 n/a Engine 1 n/a n/a 5 n/a Engine 2 n/a n/a 17 n/a I/Os Delayed by Disk I/O Structures n/a n/a 0 n/a Server Config Limit n/a n/a 0 n/a Engine Config Limit n/a n/a 0 n/a Operating System Limit n/a n/a 20 n/a Total Requested Disk I/Os 12.6 104.3 417 Completed Disk I/O's Asynchronous I/O's Total Completed I/Os 12.6 104.3 41 100.0 % Synchronous I/O's Total Completed I/Os 0.0 0.0 0 n/a ------------------------- ------------ ------------ ---------- Total Completed I/Os 12.6 104.3 417
You can also use this information to determine whether the operating system can keep pace with the disk I/O requests made by all of the engines.
