APPENDIX D
This view shows the status of locks held by or being requested by Adaptive
Server processes as of the end of the most recent sample interval. Each lock is
identified by the login name, Process ID, and Kernel Process ID of the
Adaptive Server process associated with the lock, as well as the name and ID
of the object being locked, the name and ID of the database that contains that
object, and the page number to which the lock applies (if it is a page lock). The
current status of each lock is presented, as is an indication of whether or not
this is a demand lock. If the lock is being requested by the process, the amount
of time that this process waited to acquire the lock and the Process ID of the
process that already holds the lock are shown. If instead the process already
holds the lock, the count of other processes waiting to acquire that lock is
shown.

This view represents the page I/Os for each Adaptive Server process in detail.
The login name, Process ID, Kernel Process ID, current process state and
current engine are shown for each Adaptive Server process as of the end of the
most recent sample interval. The view shows the percentage of page I/O
requests that could be satisfied by the Adaptive Server data caches, both for the
sample interval and since the start of the session.
This view also presents the number of logical page reads, physical page reads,
and page writes accumulated since the start of the recording session.
