Auto-Start

Cloverleaf is a structured high availability scheme. Cloverleaf server clusters that are configured for high availability perform as a single integration system and provide almost 100% up time. This scheme is durable and operates continuously, providing protection from unplanned down times.

Auto-healing

Sometimes, failure can happens on the primary node (Cloverleaf machine). The auto-healing toolset assists Cloverleaf to transit runtime from a primary AS/Cluster node to a secondary AS/Cluster node. See Cloverleaf auto-healing toolset. This toolset assists in:

  • Host server and security server recovery.
  • Cloverleaf engine and MonitorD recovery.
  • Cloverleaf persistence layer recovery, consisting of recovery database, SMAT database, and so on.
Note: The MonitorD can be auto-started through the Global Monitor auto-start functionality. See Configuring system and host level MonitorD auto-restart in the Global Monitor online help.

Information storage

The Windows configuration is stored at %HCIROOTDIR%\auto-start.

The Unix/Linux configuration is stored at $HCIROOT/auto-start.

On UNIX/Linux, auto-start scripts can be copied out of $HCIROOT during installation.
