We have been successfully using V2.1A for a while, but I recently
noticed that each node in the cluster is actually using a different DFG
database! (Something similar to having installed it to point
DFG$DATABASE to SYS$SPECIFIC instead of SYS$COMMON.) Anyway, I'd like
to somehow "merge" the two databases into one and put it in a common
location so that regardless of which machine runs the defrag it is
accessing the common database. I presume it's tantamount to somehow
merging the 7 DFG$*.DAT files in the DFG$DATABASEs?
Assuming what I want to do is possible, can someone please give me
guidance on how I can proceed?
Thanks!

There is a OpenVMS Merge utility that might do what you want.
I would have to play with it to see if it works.
The following is what I would do:
1. Extract the data from each database using the following
command:
$ defragment show */command/parameter/out=load_db.com
2. Edit each file
Because DCL is limited to 255 characters, you will have to go
in a edit load_db.com and remove lines that defaults. Things
are default are /level=2 -
3. Shut down the scheduler on each node.
$ @SYS$STARTUP:DFG$STOP_SCHEDULER
4. Define DFG$DATABASE as system/exec where you want it be.
5. Create a new database using the following commands:
$ run sys$system:dfg$create_database
$ run sys$system:dfg$init_database
6. Edit SYS$STARTUP:DFG$STARTUP.COM so it points to where you
want it.
7. Startup the schedulers with
$ @SYS$STARTUP:DFG$START_SCHEDULER
8. Reload the database by executing each of the @load_db.com
thanks
