Site Daemons

Site Daemons are used to control access to engine files and to monitor engine processes and threads.

UNIX users

In UNIX, two site daemons are used for each site:

  • Lock Manager controls access to files that are used by the engine. For example, error files, recovery files, SMAT files, and log files.
  • Monitor Daemon monitors the state of engine processes and threads, and supplies that information to other tools. This watches the system and site conditions, and monitors pre-defined alert conditions.

Windows users

In Windows, only the Monitor Daemon is available.

Command-line users

    • lockmgr accesses the Lock Manager.

    • console -mp queries the Lock Manager status.
    • lm -mp is the Lock Manager process.

    • Access the Monitor Daemon through hcimonitord.
    • hcisitectl, with appropriate flags, turns the Monitor Daemon on and off.
