Technical data

If this update is not installed you may encounter the following problem. If a

queue running in a multistreamed process is stopped with STOP/QUEUE/RESET,

then quickly started with START/QUEUE, it is possible that the start request

will hang. In addition, sometimes the following message will be written to

OPCOM:

%DCPS-F-STREAMUSE, Request 4 for Stream Id x ignored.

Not consistent with symbiont state

To recover, issue a Ctrl/Y to return to the DCL prompt, then issue a

STOP/QUEUE/RESET again, wait a few seconds, and try to start the queue

again. To avoid this problem, install the queue manager update.

3.3 Problem Starting Queues for LAT- and Direct-Connected

Printers

There is an OpenVMS V7.0 terminal driver problem that may hinder you in

using DCPS with LAT- and direct-connected printers. The symptom is that

the associated queue cannot be started, with messages like the following being

written to OPCOM:

%%%%%%%%%%% OPCOM 31-OCT-1995 21:53:55.73 %%%%%%%%%%%

Message from user SYSTEM on FUNYET

Queue SYS$PRINT: %DCPS-E-UNSUPPORTED, unsupported operation or

function

%%%%%%%%%%% OPCOM 31-OCT-1995 21:53:55.74 %%%%%%%%%%%

Message from user QUEUE_MANAGE on FUNYET

%QMAN-I-QUENOTSTART, queue SYS$PRINT could not be started on node

FUNYET

%%%%%%%%%%% OPCOM 31-OCT-1995 21:53:55.74 %%%%%%%%%%%

Message from user QUEUE_MANAGE on FUNYET

-SYSTEM-F-ABORT, abort

The failure may be constant or intermittent. If you subsequently attempt to start

the queue, you may succeed.

The following patch kits ﬁx this problem:

• ALPTTDR01_070, for OpenVMS Alpha V7.0 systems

• VAXTTDR01_070, for OpenVMS VAX V7.0 systems

3.4 I/O Errors for Serially-Connected Printers

There is an OpenVMS terminal driver problem that may result in your printer

reporting I/O problems when connected to a serial port of your OpenVMS system.

You may see the problem with OpenVMS Alpha V6.2 through V7.0, and with

OpenVMS VAX V5.5 through V7.0, depending in part on what kind of serial port

you are using.

The problem is that the terminal driver sometimes does not respond quickly

enough to an XOFF request from the printer to prevent the printer from losing

data.

This problem is ﬁxed in OpenVMS Alpha V7.1.

The following patch kits ﬁx this problem:

• ALPOPDR02_070, for OpenVMS Alpha V7.0 systems

• ALPOPDR04_062, for OpenVMS Alpha V6.2 systems
