DECnet: Connections to DEC Hosts Fail over Router (End Node Problem)
Configuring a DECnet Node to Log DECnet Events
In addition to the diagnostic tools available on your router, DECnet environments provide a wealth
of diagnostic information. DECnet nodes can use the DECnet Event Logging Facility (EVL) to track
DECnet events. EVL allows you to monitor significant network events, such as lost packets and
circuit failures.
The following steps outline the basic tasks required to enable event logging on a VMS system:
Step 1 Determine whether the OPCOM process is running:
$ show system
Step 2 If OPCOM does not appear in the list of running processes, enter the following command
to start it:
$ @sys$system:STARTUP.com OPCOM
Unrecognized object With this problem, users see the message “connect failed, unrecognized object.”
Step 1 Use the tell NCP command to determine whether the object is defined on
the target node. The syntax of the tell command is as follows:
tell target-node-name show known objects
Step 2 If the object is not defined, log in as superuser and run NCP to define the
object with the set object NCP command, as follows:
set object object-id
Step 3 After the object is defined, use the tell NCP command to determine
whether the object has a file specified, as follows:
tell target-node-name show object object-id character
Step 4 Exit NCP and determine whether the file specified for the object exists.
Step 5 If the file for the requested object does not exist, create the file.
Step 6 Make sure the permissions for the specified file are correct.
Insufficient resource error With an insufficient resource error, VMS

users see the following message:
% system-E-REMRSC, insufficient system resource at remote
node
Note: This error message might not indicate a problem. These parameter values
can be set intentionally to prevent network connections beyond a certain number.
Try tuning the following DEC target system parameters:
• SYSGEN parameters:
— MAXPROCESSCNT
• NCP parameters:
— MAXIMUM LINKS
— ALIAS MAXIMUM LINKS
• AUTHORIZE parameters:
— MAXJOBS
— MAXACCTJOBS
