How to Shut Down a Cluster

Do not use send brk on a cluster console to shut down a cluster node. The command is not supported within a cluster.

1. SPARC: If your cluster is running Oracle Parallel Server or Real Application Clusters, shut down all instances of the database.

   Refer to the Oracle Parallel Server or Oracle Real Application Clusters product documentation for shutdown procedures.

2. Become superuser on any node in the cluster.

3. Shut down the cluster immediately.

   From a single node in the cluster, type the following command.

   # scshutdown -g0 -y

4. Verify that all nodes are showing the ok prompt on a SPARC based system or a Boot Subsystem on an x86 based system.

   Do not power off any nodes until all cluster nodes are at the ok prompt on a SPARC based system or in a Boot Subsystem on an x86 based system.

5. If necessary, power off the nodes.

SPARC: Example—Shutting Down a Cluster

The following example shows the console output when stopping normal cluster operation and bringing down all nodes so that the ok prompt is shown. The -g 0 option sets the shutdown grace period to zero, -y provides an automatic yes response to the confirmation question. Shutdown messages also appear on the consoles of the other nodes in the cluster.

# scshutdown -g0 -y
