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/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
