Overview of Managing Oracle Clusterware Environments

The following list describes the tools and utilities for managing your Oracle Clusterware environment:

  • Cluster Health Monitor (CHM): Cluster Health Monitor detects and analyzes operating system and cluster resource-related degradation and failures to provide more details to users for many Oracle Clusterware and Oracle RAC issues, such as node eviction. The tool continuously tracks the operating system resource consumption at the node, process, and device levels. It collects and analyzes the clusterwide data. In real-time mode, when thresholds are met, the tool shows an alert to the user. For root-cause analysis, historical data can be replayed to understand what was happening at the time of failure.

  • 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.

    Install and use CVU for both preinstallation and postinstallation checks of your cluster environment. CVU is especially useful during preinstallation and during installation of Oracle Clusterware and Oracle RAC components to ensure that your configuration meets the minimum installation requirements. Also use CVU to verify your configuration after completing administrative tasks, such as node additions and node deletions.

  • 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.

  • Oracle Clusterware Control (CRSCTL): CRSCTL is a command-line tool that you can use to manage Oracle Clusterware. Use CRSCTL for general clusterware management, management of individual resources, configuration policies, and server pools for non-database applications.

    Oracle Clusterware 12c introduces cluster-aware commands with which you can perform operations from any node in the cluster on another node in the cluster, or on all nodes in the cluster, depending on the operation.

    You can use crsctl commands to monitor cluster resources (crsctl status resource) and to monitor and manage servers and server pools other than server pools that have names prefixed with ora.*, such as crsctl status server, crsctl status serverpool, crsctl modify serverpool, and crsctl relocate server. You can also manage Oracle High Availability Services on the entire cluster (crsctl start | stop | enable | disable | config crs), using the optional node-specific arguments -n or -all. You also can use CRSCTL to manage Oracle Clusterware on individual nodes (crsctl start | stop | enable | disable | config crs).

    See Also:

  • Oracle Enterprise Manager: Oracle Enterprise Manager has both the Cloud 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.

  • 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.

  • 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.


    You can only use SRVCTL to manage server pools that have names prefixed with ora.*.
