I wrote two custom scripts, rsa.pl and rsl.pl, to synchronize audio cuts
and daily logs from one RD stand-alone system to another. They do not
synchronize the rest of the database, but they do insure that a log
produced on one system will run on the other.
It is possible to use these scripts bi-directionally, i.e. changes to A
propagate to B and changes to B propagate to A; however, cart and log
deletions do not propagate. Additions and changes will propagate, but
deletions cannot, because if they did, it would be impossible to tell the
difference between a deletion from one system and an addition to the
other.
This is a feature that I wish were included in Rivendell itself. Just the
other day it saved one of my stations when the sound card in the RD system
in the on-air studio went west. We switched to the backup RD system at the
transmitter site, which is on the air right now with identical content
pending the arrival of the replacement sound card.
I can send you copies of these scripts if you think they will be useful.
They will not work on RD 3.x, which I am told has a completely different
database structure.

I'm preparing two CentOS 7 Riv 2.19 machines for an LPFM. The owner would like
a main airplay and a production machine that
syncs with the airplay.
I'm looking for good options that he could easily manage since he's not a Linux
person. The options I think of are to make
one a server and the other a client, or make them both stand-alones that have a
scripted audio sync and DB replicator
between them. My experience with the DB replication is that if he reboots one
of them, it will stop replicating until
re-synced which is going to be beyond his ability. I have not played with
replication on MariaDB. Perhaps there is a way to
automate this that I don't know about. Other suggestions to make this simple
and somewhat foolproof?
Thanks,
