Hi,

In DB mode 2, DB only replication is not enough as the mem cache on backup machine will never be updated with the registrations. So you end up with a discrepancy (on backup) between what opensips has in memory and what you have in DB (in terms of registered contacts). You definitely need a data level replication too (to update the usrloc cache on the backup too).

Its replicated at the DB level, using Mysql replication

    Hi,

    How do you get the registrations "replicated" on the backup server
    ? (the in memory data)

    Take a look at the "m" flag for "save()" function:

    Hi

    I'm using usrloc with db_mode set to 2, I'm using a backup server
    which is always running and is using the same database, my
    problem is that the second server constantly removes records from
    the location table, is it possible to  disable the expired
    contacts timer? would setting timer_interval to 0 disable the
    timer? I can write a cron that would delete expired contacts. is
    there any downside to this? does the timer do anything else? the
    documentation says "The timer deletes all expired contacts and
    flushes all modified or new contacts to database" I'm not exactly
    what they mean by flushing the modified or new contacts.

    Both servers have exact same system time so that's not the issue.

    If there is a better way please let me know.
