Updating the Permanent Data Base
The master copies of the permanent data bases for the DECnet routers
is on UXCSB1. Backup copies are stored on UXDDB1. Updating the permanent
data base requires privileged access to these nodes and should be
normally be performed by the DECnet Coordinator. The information given
here is only expected to be used in case of urgent changes requiring
a router to reboot.
First update the permanent data base on UXCSB1:
$ run sys$system:x25rouperm
it asks you for the name of the router you want to modify ...
X25ROUPERM> enter here your NCP commands
e.g. set circ x25-spain cost 23
X25ROUPERM> exit
Now copy the files to UXDDB1:
copy sys$common:[decserver]x25cernr*.sys uxddb1::sys$common:[decserver]
You may need help from the UXDDB1 system manager for the copy.
You must notify any changes of the permanent data base to the DECnet
Coordinator since she does not configure the routers using the above
mechanism. In order to have a documented record and to ease the configuration
of future routers, the DECnet Coordinator has chosen to enter NCP
commands in command files stored on UXCSB1 in the directory tree sys$common:[sysmgr.decnet].
These command files are invoked from within the X25ROUPERM program
rather than entering the individual commands by hand.
