On the master system:
1. Get all users out of the master database.
2. Flush all of the records through to the shadow database and then stop posting in the shadow
node. This can be accomplished by running the following program on the master machine:
RUN NBFLUSH.PUB.NETBASE,STOPWAIT;PARM=node
When this program finishes, all the records for the shadow machine will be flushed and posted
and then the posting process will be stopped. The node number specified is the node number of
the shadow node.
3. Make a backup copy of the database. This is only a precautionary measure should the capacity
change fail.
4. Make your database changes with your favorite database tool. (Remember these tools should
not go through NetBase.)
5. Let the users back onto the master database.
On the shadow system:
1. Make your capacity changes (the same ones made to the master).
2. Run NBCTRL and enter the START POST command. This restarts the posting process.
