Overview of SRVCTL for Administering Real Application Clusters

The Server Control (SRVCTL) utility is installed on each node by default. You can use SRVCTL to start and stop the database and instances, manage configuration information, and to move or remove instances and services. SRVCTL also manages configuration information.

Some SRVCTL operations store configuration information in the Oracle Cluster Registry (OCR). SRVCTL performs other operations, such as starting and stopping instances, by sending requests to the Oracle Clusterware process (CRSD), which then starts or stops the Oracle Clusterware resources.

To use SRVCTL, enter the srvctl command and its options in case sensitive syntax as described under the heading "SRVCTL Command Reference".

Guidelines for Using SRVCTL in Real Application Clusters

Guidelines for using SRVCTL are:

To use SRVCTL to change your RAC database configuration, log in to the database as the oracle user. Members of the DBA group can start and stop the database.
Only use the version of SRVCTL that is provided with Oracle Database 10g on RAC databases that are created or upgraded for Oracle Database 10g.
Always use SRVCTL from the Oracle_home of the database that you are administering.
SRVCTL does not support concurrent executions of commands on the same object. Therefore, only run one SRVCTL command at a time for each database, service, or other object.

Obtaining Command-Line Help for SRVCTL

To see help for all SRVCTL commands, from the command line enter:

srvctl -h

To see the command syntax and a list of options for each SRVCTL command, from the command line enter:

srvctl command (or verb) object (or noun) -h

To see the SRVCTL version number enter:

srvctl -V

Caution:

Although you may be able to cancel running SRVCTL commands by entering Control-C at the command line, you may corrupt your configuration data by doing this. You are strongly advised not to attempt to terminate SRVCTL in this manner.

SRVCTL Command Syntax and Options

SRVCTL commands, objects, and options are case sensitive. Database, instance, and service names are case insensitive and case preserving. SRVCTL interprets the following command syntax:

srvctl command object [options]

In SRVCTL syntax:

srvctl is the command to start the SRVCTL utility.
command is a verb such as start, stop, or remove.
object is an object or target on which SRVCTL performs the command, such as database or instance. You can also use object abbreviations.
options extend the use of a preceding command combination to include additional parameters for the command. For example, the -i option indicates that a comma-delimited list of instance names follows; sometimes the -i option only permits one value and not a list of names. The -n option indicates that a node name or a comma-delimited list of node names follows. SRVCTL prompts for user credentials when you use the -q option with any SRVCTL command.

Note:
Enclose comma-delimited lists in double-quote ("...,..." ) symbols.

SRVCTL Cluster Database Configuration Tasks

The database configuration tasks are:

Add, modify, and delete cluster database configuration information.
Add an instance or a service to, and delete an instance or service from the configuration of a cluster database.
Move instances and services in a cluster database configuration and modify service configurations.
Set and unset the environment for an instance or service in a cluster database configuration.
Set and unset the environment for an entire cluster database in a cluster database configuration.

SRVCTL General Cluster Database Administration Tasks

The general database administration tasks are:

Start and stop cluster databases
Start and stop cluster database instances
Start, stop, and relocate cluster database services
Obtain statuses of cluster databases, cluster database instances, or cluster database services

SRVCTL Node-Level Tasks

The node-level tasks are:

Adding and deleting node level applications.
Setting and unsetting the environment for node-level applications.
Administering node applications.
Administering ASM instances.
Starting and stopping a group of programs that includes virtual IP addresses, Listeners, Oracle Notification Services, and Oracle Enterprise Manager agents (for maintenance purposes).

SRVCTL Command Reference

This section presents the SRVCTL command reference:

srvctl add
srvctl config
srvctl enable
srvctl disable
srvctl start
srvctl stop
srvctl modify
srvctl relocate
srvctl status
srvctl getenv
srvctl setenv and unsetenv
srvctl remove

SRVCTL Commands

This section summarizes the SRVCTL commands, objects, and options. Oracle recommends that you use the DBCA to create your RAC database as well as your initial service configurations. This is because the DBCA configures both the Oracle Clusterware resources and the Net Service entries for each service.

srvctl add

The SRVCTL add command adds the configuration and the Oracle Clusterware applications to the OCR for the cluster database, named instances, named services, or for the named nodes. To perform srvctl add operations, you must be logged in as the database administrator and be the Oracle account owner on UNIX-based systems, or you must be logged on as a user with Administrator privileges on Windows-based systems.

When adding an instance, the name that you specify with -i must match the ORACLE_SID parameter. The database name given with -d db_unique_name must match the DB_UNIQUE_NAME initialization parameter setting. If DB_UNIQUE_NAME is unspecified, then match the DB_NAME initialization parameter setting. The default setting for DB_UNIQUE_NAME uses the setting for DB_NAME. Also, the domain name given with -m db_domain must match the DB_DOMAIN setting.

The SRVCTL enable command enables the named object so that it can run under the Oracle Clusterware for automatic startup, failover, or restart. The Oracle Clusterware application supporting the object may be up or down to use this function. Enable is the default value. If the object is already enabled, then the command is ignored. Enabled objects can be started, and disabled objects cannot be started.

Table E-14 srvctl enable Summary

Command	Description
srvctl enable database	Enables the database.
srvctl enable instance	Enables the instance.
srvctl enable service	Enables a service.
srvctl enable asm	Enables an ASM instance.

srvctl enable database

Enables the Oracle Clusterware resources for a database and enables the database's instances if the database was previously disabled.

Syntax and Options

Use the srvctl enable database command with the following syntax:

srvctl enable database -d db_unique_name

The only option available for this command is -d to specify the database name.

Example

An example of this command is:

srvctl enable database -d crm

srvctl enable instance

Enables an instance for the Oracle Clusterware. If all instances are disabled, then enabling an instance also enables the database.

Syntax and Options

Use the srvctl enable instance command with the following syntax:

Example

An example of this command is:

srvctl enable instance  -d crm -i "crm1,crm2"

srvctl enable service

Enables a service for the Oracle Clusterware. Enabling an entire service also affects the enabling of the service over all of the instances by enabling the service at each one. When the entire service is already enabled, an srvctl enable service operation does not affect all of the instances and enable them. Instead, this operation returns an error. Therefore, you cannot always use the entire set of service operations to manipulate the service indicators for each instance.

Syntax and Options

Use the srvctl enable service command with the following syntax:

srvctl enable service -d db_unique_name {-s service_name_list | -s service_name -i inst_name}

Table E-16 srvctl enable service Options

srvctl enable asm -n node_name [-i asm_inst_name]

Table E-17 srvctl enable asm Option

Option	Description
`-n` `node_name`	Node name
`-i` `inst_name`	ASM instance name.

Example

An example of this command is:

srvctl enable asm -n crmnode1 -i asm1

srvctl disable

Disables a specified object (cluster database, database instance, ASM instance, or service). SRVCTL disable is intended to be used when an object is to be repaired or is down for maintenance to prevent inappropriate automatic restarts. When you issue the disable command, the object is disabled and unavailable to run under the Oracle Clusterware for automatic startup, failover, or restart. If you specify -i instance_name, then SRVCTL only disables the service from running on the specified instance.

Table E-18 srvctl disable Summary

Command	Description
srvctl disable database	Disables the cluster database
srvctl disable instance	Disables an instance
srvctl disable service	Disables a service
srvctl disable asm	Disables an ASM instance

The only option available for this command is -d to specify the database name.

Example

An example of this command is:

srvctl disable database -d mybd1

srvctl disable instance

Disables an instance. If the instance that you disable with this command is the last enabled instance, then this operation also disables the database.

Syntax and Options

Table E-19 srvctl disable instance Options

Option	Description
`-d` `db_unique_name`	Unique name for the database.
`-i inst_name_list`	Comma-delimited instance names.

Example

An example of this command is:

srvctl disable instance -d crm -i "crm1,crm3"

srvctl disable service

Disables a service. Disabling an entire service affects all of the instances, disabling each one. When the entire service is already disabled, an srvctl disable service operation on the entire service affect all of the instances and disable them; it just returns an error. This means that you cannot always use the entire set of service operations to manipulate the service indicators for each instance.

Syntax and Options

Use the srvctl disable service command with the following syntax:

srvctl disable service -d db_unique_name {-s service_name_list | -s service_name -i inst_name}

Table E-20 srvctl disable service Options

Option	Description
`-d` `db_unique_name`	Unique name for the database.
`-s` `service_name_list`	Comma-delimited service names.
`-s` `service_name`	Single service name.
`-i inst_name`	Instance name.

Examples

The following example globally disables two services:

srvctl disable service -d crm -s crm,marketing

The following example disables a service running on the preferred named instance and results in running a service on one less instance:

srvctl disable service -d crm -s crm -i crm1

srvctl start

Starts Oracle Clusterware enabled, non-running applications for the database, all or named instances, all or named service names, or node-level applications. For the start command, and for other operations that use a connect string, if you do not provide a connect string, then SRVCTL uses "/ as sysdba" to perform the operation. To run such operations, the owner of the oracle binary executables must be a member of the OSDBA group, and users running the commands must be in the OSDBA group also.

Stops the Oracle Clusterware applications for the database, all or named instances, all or named service names, or node level applications. Only the Oracle Clusterware applications that are starting or running are stopped. Objects running outside of the Oracle Clusterware are not stopped. Stops node-level applications and all dependent Oracle Clusterware applications on the node.

You should disable an object that you intend to remain stopped after you issue a SRVCTL stop command. Refer to the SRVCTL disable command starting with srvctl disable database.

Note:

If the object is stopped and is not disabled, then it can restart as a result of another planned operation. That is, the object will not restart as a result of a failure. Oracle recommends that you disable an object that should remain stopped after you issue a stop command.

srvctl modify service

Moves a service member from one instance to another. Additionally, this command changes which instances are to be the preferred and the available instances for a service. This command supports some online modifications to the service, for example:

When a service configuration is modified so that a new preferred or available instance is added, the running state of the existing service is not affected. However, the newly added instances will not automatically provide the service, until a srvctl start service command is issued as described.
When there are available instances for the service, and the service configuration is modified so that a preferred or available instance is removed, the running state of the service may change unpredictably:
- The service is stopped and then removed on some instances according to the new service configuration.
- The service may be running on some instances that are being removed from the service configuration.
- These services will be relocated to the next "free" instance in the new service configuration.

As a result of these considerations, when the online service is being modified, users may experience a brief service outage on some instances even if the instances are not being removed. Or users may experience a brief service outage on instances that are being removed from the service.

Important:

Oracle recommends that you limit configuration changes to the minimum requirement and that you not perform other service operations while the online service modification is in progress.

Syntax and Options

Use the srvctl modify service command with the following syntax:

Removes the configuration, the Oracle Clusterware applications for the node (including the virtual IP address, the Oracle Enterprise Manager agent, the GSD, and the Listeners), the database, named instances, or the named services from the cluster database. Environment settings for the object are also removed.

If you do not use the force flag (-f), then Oracle prompts you to confirm whether to proceed. If you use the force (-f) option, then the remove operation proceeds without prompting and continues processing even when it encounters errors. Even when the Oracle Clusterware resources cannot be removed, the OCR configuration is removed, so that the object now appears not to exist, but there are still Oracle Clusterware resources. Use the -f option with extreme caution because this could result in an inconsistent OCR.

To use the remove verb, you must first stop the node applications, database, instance, or service for which you are specifying srvctl remove. Oracle recommends that you perform a disable operation before using this command, but this is not required. You must stop the target object before running the srvctl remove command. The srvctl stop command is described.
