Managing Supervisors and Physical Printers

Querying for Supervisor Information

This section describes how to query for the values of attributes that

reﬂect the state of and information about HPDPS supervisors and the

associations between the supervisor and other HPDPS objects.

You can query for supervisor information in response to notiﬁcation

messages that indicate a problem with either the supervisor or a

physical printer. Because the supervisor controls the physical printer,

problems with a physical printer can be caused by problems with the

supervisor in which the physical printer resides.

Querying for the State of a Speciﬁc Supervisor

The value of the non-settable server-state supervisor attribute

indicates the state of the supervisor. You can query the state of the

supervisor if you receive a notiﬁcation message about a problem in the

supervisor or a message that indicates the supervisor has started to

terminate. You can query the supervisor if jobs are being rejected

because no physical printers are available to support the jobs; the

supervisor could be down and the spooler can no longer communicate

with it.

For example, to query for the state of the supervisor Super1, enter:

pdls -c server Super1

HPDPS displays information similar to the following:

Server State Type

------ ----- ---------

Super1 ready supervisor

The server-state attribute is one of the predeﬁned attributes of the

brief option of the -r ﬂag for the pdls command. The default for the -r

ﬂag is brief; therefore, the command you entered in this example is

equivalent to entering:

pdls -c server -r brief Super1

If the supervisor is not running, HPDPS issues a message that it cannot

communicate with the server. See “Restarting the Supervisor After It

Has Been Shut Down” later.
