Scaling Up to Standard RAC
The following command initiates the online upgrade of a RAC One Node database to a fully functional RAC database:
srvctl convert database -d RONDB -c RAC
The following slightly modified syntax is for use on a 12c database for database conversion:
$srvctl convert database -db db_unique_name -dbtype RAC [-node node_name]
In this command, the parameter
-c
(replaced as
-dbtype
in 12c) has two options:
RAC
and
RACONENODE.
Specify
RAC to scale upwards, taking a RAC One Node database to a standard RAC database.
Execute the
srvctl convert database
command on the node on which RAC One Node is running. Otherwise,
you will get the following error message:
PRKO-2159 : Option '-i' should be specified to convert an administrator-managed RAC database to its
equivalent RAC One Node database configuration
Specify the
-n
option when the RAC One Node database is not running on the local node. The following is the
syntax to use:
$ rvctl convert database -d <dbname> -c RAC [-n <node_name>]
In this syntax, the parameter
-n
specifies the node name on which the RAC One Node database is running.
When the conversion procedure completes successfully, you can verify the database configuration to ensure
that the database has successfully converted to RAC. Do so by issuing the
srvctl config
command as in the
following example:
$ srvctl config database -d RONDB
Database unique name: RONDB
Database name: RONDB
..........
Database instances: RONDB_2
Disk Groups: DG_RONDB
Mount point paths:
Services: RONDB_MAIN
Type: RAC
Database is administrator managed
At this point, you now have a full-fledged RAC database with a single instance. You will have to add additional
instances according to your business needs. You can do so using the following syntax:
$ srvctl add instance -d RONDB -i RONDB_1 -n rac2
After adding an instance, bring up the new instance using the following srvctl command:
$ srvctl start instance -d RONDB -i RONDB_1
The RONDB database now has two instances. Verify using the following command:
$ srvctl status database -d RONDB
