Administrative Tools for Oracle RAC Environments:

Administrative Tools for Oracle RAC Environments(Source: Oracle Documentation)

Oracle enables you to administer a cluster database as a single system image through
Oracle Enterprise Manager, SQL*Plus, or through Oracle RAC command-line
interfaces such as Server Control Utility (SRVCTL):

■ Oracle Enterprise Manager: Oracle Enterprise Manager has both the Database
Control and Grid Control GUI interfaces for managing both noncluster database
and Oracle RAC database environments. Oracle recommends that you use Oracle
Enterprise Manager to perform administrative tasks whenever feasible.
You can use Oracle Enterprise Manager Database Control to also manage Oracle RAC One Node databases.

■ Server Control Utility (SRVCTL): SRVCTL is a command-line interface that you can use to manage an Oracle RAC database from a single point. You can use
SRVCTL to start and stop the database and instances and to delete or move
instances and services. You can also use SRVCTL to manage configuration
information, Oracle Real Application Clusters One Node (Oracle RAC One Node),
Oracle Clusterware, and Oracle ASM.

■ SQL*Plus: SQL*Plus commands operate on the current instance. The current
instance can be either the local default instance on which you initiated your
SQL*Plus session, or it can be a remote instance to which you connect with Oracle
Net Services.
■ Cluster Verification Utility (CVU): CVU is a command-line tool that you can use
to verify a range of cluster and Oracle RAC components, such as shared storage
devices, networking configurations, system requirements, and Oracle Clusterware,
in addition to operating system groups and users. You can use CVU for
preinstallation checks and for postinstallation checks of your cluster environment.
CVU is especially useful during preinstallation and during installation of Oracle
Clusterware and Oracle RAC components. Oracle Universal Installer runs CVU
after installing Oracle Clusterware and Oracle Database to verify your
environment.
Install and use CVU before you install Oracle RAC to ensure that your
configuration meets the minimum Oracle RAC installation requirements. Also, use
CVU for verifying the completion of ongoing administrative tasks, such as node
addition and node deletion.

■ DBCA: DBCA is the recommended method for creating and initially configuring Oracle RAC, Oracle RAC One Node, and Oracle noncluster databases.

■ NETCA: Configures the network for your Oracle RAC environment.
