Removing MC/LockManager from a System

This chapter includes information about carrying out routine maintenance tasks on an Oracle Parallel Server configuration. Tasks include:

Viewing the Status of the Cluster
Starting and Stopping the Cluster
Starting and Stopping Individual Nodes
Managing Packages and Services
Changing the Permanent Cluster Configuration
Changing Oracle Parameters (OPS 7.3.x)
Making Volume Groups Shareable
Activating a Volume Group in Shared Mode
Making Changes to Shared Volume Groups
Adding Additional Shared Volume Groups
Single-Node Operation
Removing MC/LockManager from a System

Refer to Appendix A for a complete list of man pages that relate to these tasks. The man pages contain additional useful information.




	NOTE: You must be very careful to carry out all cluster management steps on only `one node at a time`. Be sure to exit from SAM on one node before running SAM on another node in the cluster to avoid any chance of one node's overwriting the cluster configuration that was defined on the other node. In general, it is simpler to carry out all configuration tasks on one "configuration node."
