The number of DBEnvironment sessions.

PID

The HP-UX process identification number of the DBEnvironment session.

LOGIN NAME

The HP-UX login name of the DBEnvironment session.

STATUS

The status of the DBCore call the session has made. This field is equivalent to the STATUS column of the SYSTEM.CALL pseudotable. The possible values are listed below:

Running

DBCore is processing a call from a session.

Waiting for resource

The session has made a DBCore call, but is waiting until it can acquire a resource that is currently unavailable. The resource can be LOCK, LATCH, BUFFER, THROTTLE, or XACT.

Idle

DBCore is not processing a call.

XID

The transaction identifier, equivalent to the XID column of the SYSTEM.TRANSACTION pseudotable.

ISO

The isolation level, equivalent to the ISOLATION LEVEL column of the SYSTEM.TRANSACTION pseudotable. For more information, see the chapter "Concurrency Control through Locks and Isolation Levels" in the ALLBASE/SQL Reference Manual.

PRI

The transaction priority, equivalent to the PRIORITY column of the SYSTEM.TRANSACTION pseudotable. The lowest transaction priority is 255, and the highest is 0.

LABEL

The transaction label, equivalent to the LABEL column of the SYSTEM.TRANSACTION pseudotable. To assign a label to a transaction, use a BEGIN WORK statement or a SET TRANSACTION statement.

PROGRAM NAME

The name of the program being run, usually the parent process of the process actually connected to the DBEnvironment. All of the sessions running a program are listed beneath the PROGRAM NAME.

Display Conventions

When a session is displayed in inverse video, it is waiting for a resource, probably a lock.
