The lines listing the server names should appear on one
continuous line. The are wrapped in the document due to page
limitations.
Note:
5.
Add the Oracle Database ORACLE_HOME directory to the new servers by
running the addNode.sh script from an existing server as the database owner user.
$ cd $ORACLE_HOME/oui/bin
$ ./addNode.sh -silent -responseFile /path/to/add-db-nodes.rsp
6.
Ensure the $ORACLE_HOME/oui/oraparam.ini file has the memory settings that
match the parameters set in the Grid Infrastructure home.
7.
Run the root.sh script on each server when prompted as the root user using the
dcli utility.
$ dcli -g new_db_nodes -l root \
/u01/app/oracle/product/11.2.0/dbhome_1/root.sh
In the preceding command, new_db_nodes is the file with the list of new database
servers.
8.
Verify the ORACLE_HOME directories have been added to the new servers using
the following command:
# dcli -g /root/all_group -l root du -sm \
/u01/app/oracle/product/11.2.0/dbhome_1
Task 10 Adding Database Instance to the New Servers
Before adding the database instances to the new servers, check the following:
■
■
■
■
Maximum file size: If any data files have reached their maximum file size, then the
addInstance command may fail with an ORA-740 error. Oracle recommends you
check that none of the files listed in DBA_DATA_FILES have reached their
maximum size. Files that have reached their maximum should be corrected.
Online redo logs: If the online redo logs are kept in the directory specified by the
DB_RECOVERY_FILE_DEST parameter, then ensure the space allocated is
sufficient for the additional redo logs for the new instances being added. If
necessary, then increase the size for the DB_RECOVERY_FILE_DEST_SIZE
parameter.
Total number of instances in the cluster: Set the value of the initialization
parameter cluster_database_instances in the spfile for each database to the
total number of instances that will be in the cluster after adding the new servers.
The HugePages settings are correctly configured on the new servers to match the
existing servers.
The following procedure describes how to add database instances to the new servers:
1.
Use a command similar the following from an existing database server to add
instances to the new servers. In the command, the instance, dbm9, is being added
for server dm02db01.
dbca -silent -addInstance -gdbName dbm -nodeList dm02db01 -instanceName dbm9 \
-sysDBAUsername sys
