Search BC Oracle Sites.To manage the RAC environment, first build a configuration profile and optionally save it. The configuration can be built by commands such as add and setenv. Alternatively, abbreviations can be used, which in this case are db and inst respectively.
Modify Modifies the instance configuration. Start Starts the database or instance. Status Status of the database or instance. Stop Stops the database or instance. Service serv To add, configure, modify, manage environment variables for, enable, start, obtain the status of, relocate, disable, stop, and remove services from your cluster database. Table 8. Some commonly used commands will be examined next. This command adds configuration information for the database or for named instances.
Command specific actions for add command:.
For example, to add a new database:. This command displays a list of configured databases. The syntax is:. For example, to display configured databases:. This command displays values for the environment from the SRVM configuration file. This command sets values for the environment in the SRVM configuration file.
srvctl stop home
Name of an instance can't be changed. The users will now be getting connected to another instance. The instance you are connected to will be shutdown.
Let's say you are connected to 'instance1' and you 'shutdown immediate'only instance 1 will be shut down and other instance instance 2 will still be available for users. When you shutdown the instance 1all the users on instance 1 running 'select' queries will failover to instance 2 BUT all the users executing any DML's will be killed and new session will be connected to instance 2.

How to rectify this issue?? Umesh Gupta wrote: Any Suggestion Friends. To manage the 10g databases you must use 10g srvctl. Hi, you should always use the srvctl from the corresponding home the ressource belongs to. If both versions are the same it will work, if versions are different e. GI I one registered an ASM instance with the wrong srvctl from a different home, and had lots of problems.
Finding out what my error was took quite a long time Regards Sebastian.In this article we will be performing Oracle 11g to 12c database upgrade with data guard and ASM configured. Disable oracle restart srvctl : We must remove database from srvctl utility as it might auto restart database during upgrade process which we do not want. Once upgrade is done, we will re-register database with 12c srvctl utility.
Download and upgrade oracle 12c grid software as grid user : We will now download and upgrade oracle 12c grid software in a new grid home location. Note, you cannot have two grid softwares on a server.
srvctl stop instance
Hence, you can only upgrade any previous version of grid. Note: In any grid environment, first we have to upgrade the grid software and then the database software. The grid software can be of same or higher release than the database. Start the run installer and install oracle 12c database software on standby: Now its time to install oracle 12c in a new home. Shutdownstandby database if running from old home: Shutdown the database which is running via old oracle 11g home. Copy tnsnames. Modify oracle user environment variables: Update oracle user bash profile to point new 12c oracle home.
Mount the standby via 12c home: Now that bash profile is pointing to 12c home, mount the standby database and start MRP apply. Register with oracle 12c restart srvctl : We need to register standby database with srvctl utility as it will help us manage database easly. Note: even though we can start stop standby database via srvctl utility, we must always start MRP manually. For upgrade, you must have 4 GB allocated both on primary and standby. Note, you cannot install two grid software on a server.
Update new oracle home in listener: We must also update the listener file to point new 12c home location as grid user. Make sure DB is still up and running via 11g home. Note, we are not stopping log shipping from primary. Log shipping will continue.

You can use SRVCTL to start and stop the database and instances, manage configuration information, and to move or remove instances and services. For example, if you installed Oracle Database and ASM in separate homes and each one has a different owner, then log in as the database user to manage databases and log in as the ASM user to manage ASM instances. Users who are members of the dba group can start and stop the database. You must run SRVCTL commands from the bin directory in the Oracle Clusterware home when performing any operation related to node applications for example, srvctl add nodeappsand from the respective home of the Oracle Listeners, ASM instances, Oracle RAC databases and their instances, and Services when performing any operation on those objects.
Database, instance, and service names are case insensitive and case preserving. You can also use object abbreviations. For example, the -i option indicates that a comma-delimited list of preferred 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.
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 entire cluster database in a cluster database configuration. Starting and stopping a group of programs that includes virtual IP addresses, listeners, and Oracle Notification Services.
Execute SRVCTL commands from the command line and specify one or more objects with the appropriate options for the command and its objects.
Obtains the status of the node applications, database, database instance, ASM instance, or service. Displays the environment variable in the configuration for the node applications, database, database instance, or service. Sets and unsets the environment variable in the configuration for the node applications, database, database instance, or service.
Use the full name or the abbreviation for the purpose described. To add, configure, modify, manage environment variables for, enable, start, obtain the status of, stop, disable, and remove databases.

To add, configure, modify, manage environment variables for, enable, start, obtain the status of, relocate, disable, stop, and remove services from your cluster database.
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 Linux and UNIX systems, or you must be logged on as a user with Administrator privileges on Windows systems.
Table A-4 srvctl add database Options. The name of the database, where it is different from the unique name given by the -d option.
Table A-5 srvctl add instance Options. Adds services to a database and assigns them to instances. If you have multiple instances of a cluster database on the same node, then always use only one instance on that node for all of the services that node manages.
Use the srvctl add service command with the following syntax:. Table A-6 srvctl add service Options.Here, we can see the primary and standby configuration Let us verify the status and configuration of the RAC database In this situation, we will be pushed to make the available standby database which is with most recent recovery to be converted into primary and reduce the downtime of the database and make the database available for continuation of the business.
A Pre-Checks for Failover 1 Ensure primary is using Flashback for reinstate the failed primary 2 Flush any unsent redo in primary 3 Verify the standby database has the most recent archived redo log from each primary redo thread 4 Identify and resolve any archived redo log gaps 5 Repeat Step 4 until all gaps are resolved for each thread. B Failover 1 Stop Redo Apply 2 Finish applying all received redo data 3 Verify that the target standby database is ready to become a primary database 4 Switch the physical standby database to the primary role 5 Open the new primary database.
In order to reinstate the failed primary database, the flashback option must be enabled in the primary. If the flashback is disabled, follow the below step to enable flashback in the primary. This should be done before the failover.
If the above command returns any value, go for step III. Else set a proper directory or diskgroups. Step 2 — Finish applying all received redo data Step 3 — Verify that the target standby database is ready to become a primary database Step 4 — Switch the physical standby database to the primary role Step 5 — Open the new primary database So, if we use srvctl the secondary instance will shutdown as below.
Note:- We can modify the database configuration details as below and use srvctl if we need. In 18c Datapump. Instance status: Open. Instance ORCL2 is running on node prodrac Dataguard Rac. You may also like. Get updated. Share via. Copy Link. Copy Copied. Powered by Social Snap.
