# 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.
