In Oracle® Clusterware Administration and Deployment Guide 11g Release 2 (11.2) , the section, Overview of Managing Oracle Clusterware Environments , says that there are several ways of managing clusterware environments:
- Oracle Enterprise Manager : Oracle Enterprise Manager has both the Database Control and Grid Control GUI interfaces for managing both single instance and Oracle RAC database environments. It also has GUI interfaces to manage Oracle Clusterware and all components configured in the Oracle grid infrastructure installation. Oracle recommends that you use Oracle Enterprise Manager to perform administrative tasks, including applying patches.
- Cluster Verification Utility (CVU) : CVU is a command-line utility that you use to verify a range of cluster and Oracle RAC specific components. Use CVU to verify shared storage devices, networking configurations, system requirements, and Oracle Clusterware, and operating system groups and users.
- Server Control (SRVCTL) : SRVCTL is a command-line interface that you can use to manage Oracle resources, such as databases, services, or listeners in the cluster.
- Oracle Clusterware Control (CRSCTL) : CRSCTL is a command-line tool that you can use to manage Oracle Clusterware. CRSCTL should be used for general Clusterware management and management of individual resources.
- Oracle Interface Configuration Tool (OIFCFG) : OIFCFG is a command-line tool for both single-instance Oracle databases and Oracle RAC environments. Use OIFCFG to allocate and deallocate network interfaces to components. You can also use OIFCFG to direct components to use specific network interfaces and to retrieve component configuration information.
- Oracle Cluster Registry Configuration Tool (OCRCONFIG) : OCRCONFIG is a command-line tool for OCR administration. You can also use the OCRCHECK and OCRDUMP utilities to troubleshoot configuration problems that affect OCR
