Sun Java System Calendar Server 6.3 Administration Guide

ProcedureDetecting and Fixing Database Deadlocks

If the Berkeley database is in a deadlock state, you must reset the database. It is important to detect this condition as early as possible.

To enable the system to periodically check the databases to detect a deadlock state and inform the Administrator:

  1. Log in as an administrator with permission to change the configuration.

  2. Stop Calendar Server services by issuing the stop-cal command.

  3. Change to the /etc/opt/SUNWics5/cal/config directory.

  4. Save your old ics.conf file by copying and renaming it.

  5. Edit the ics.conf, if necessary, to have the following value:

    local.caldb.deadlock.autodetect=”yes”


    Note –

    When this parameter is set to “yes”, the db_deadlock daemon is launched that will monitor the lock region.
