NAME

       ovdb_monitor - Database maintenance

SYNOPSIS

       Use ovdb_init to start ovdb_monitor

DESCRIPTION

       When started (normally by ovdb_init that is invoked by rc.news), ovdb_monitor forks three
       processes that perform routine database maintenance tasks.  These are transaction
       checkpointing (every 30 seconds), deadlock detection (every 30 seconds), and transaction
       log removal (every 45 seconds).

       The process ID of the parent is written to ovdb_monitor.pid in the pathrun directory.
       This PID is used by other INN commands to verify that ovdb_monitor is running.

       To shut down ovdb_monitor, send a TERM signal to the process ID in ovdb_monitor.pid.  The
       parent process will shut down the three children and wait for their exit before exiting
       itself.  Note that when running the "rc.news stop" command to stop the news system,
       rc.news automatically takes care of stopping ovdb_monitor.
