13.11 Solving Queue Manager Problems
13.11.5.1 Investigating the Problem
Perform the following steps:
1. Search the operator log that was current when the problem existed for the
following messages. These messages are broadcast every 30 seconds after the
affected node boots.
%%%%%%%%%%% OPCOM 4-FEB-2000 15:36:49.15 %%%%%%%%%%%
Message from user QUEUE_MANAGE on ZNFNDL
%QMAN-E-COMMERROR, unexpected error #5 in communicating with node CSID 000000
%%%%%%%%%%% OPCOM 4-FEB-2000 15:36:49.15 %%%%%%%%%%%
Message from user QUEUE_MANAGE on ZNFNDL
-SYSTEM-F-WRONGACP, wrong ACP for device_
2. Compare the node’s value for the system address parameters SCSNODE and
SCSSYSTEMID with the values for the DECnet node name and node ID, as
follows:
$ RUN SYS$SYSTEM:SYSMAN
SYSMAN> PARAMETERS SHOW SCSSYSTEMID
Parameter Name Current Default Min. Max. Unit Dynamic
-------------- ------- ------- ------- ------- ---- -------
SCSSYSTEMID 19941 0 -1 -1 Pure-numbe
SYSMAN> PARAMETERS SHOW SCSNODE
Parameter Name Current Default Min. Max. Unit Dynamic
-------------- ------- ------- ------- ------- ---- -------
SCSNODE "RANDY " " " " " "ZZZZ" Ascii
SYSMAN> EXIT
$ RUN SYS$SYSTEM:NCP
NCP> SHOW EXECUTOR SUMMARY
Node Volatile Summary as of 5-FEB-2000 15:50:36
Executor node = 19.45 (DREAMR)
State = on
Identification = DECnet for OpenVMS V7.2
NCP> EXIT
$ WRITE SYS$OUTPUT 19*1024+45
19501
13.11.5.2 Cause
If the DECnet node name and node ID do not match the SCSNODE and
SCSSYSTEMID system address parameters, IPC (interprocess communication,
an operating system internal mechanism) cannot work properly and the affected
node will not be able to participate in the queuing system.
13.11.5.3 Correcting the Problem
Perform the following steps:
1. Modify the system address parameters SCSNODE and SCSSYSTEMID or
modify the DECnet node name and node ID, so the values match.
For more information about these system parameters, refer to the OpenVMS
System Management Utilities Reference Manual. For more information about
the DECnet node name and node ID, refer to the DECnet for OpenVMS Guide
to Networking.
2. Reboot the system.
