3 Configuring the Repository Database for Oracle
This chapter contains the following topics:
• “About Configuring the Repository Database for Oracle” (page 29)
• “Creating and Configuring the Repository Database for Oracle” (page 29)
About Configuring the Repository Database for Oracle
After installing SF Oracle RAC, you can create and configure the repository database using the
sfua_db_config script. Configuring the repository database will enable you to use SF Oracle
RAC features such as Checkpoint, FlashSnap and Storage Mapping. The script detects that the
system is running in an HA configuration and automatically configures the repository database.
Creating and Configuring the Repository Database for Oracle
Before running the sfua_db_config script, review the following requirements:
• Make sure a disk group exists with at least one volume, which should not be shared. A VxFS
file system must be created on the disk group.
• The volume must be mounted.
• Obtain an unique virtual IP address for public NIC interface.
• Obtain a device name for the public NIC interface (for example: lan0).
• Obtain a subnet mask for the public NIC interface.
NOTE: The volume is used to store the repository database.
Table 3-1 indicates the options available for the sfua_db_config script.
Table 3-1 sfua_db_config options
DescriptionOptions
Use this option in a high availability (HA) configuration. The option indicates that
ssh and scp are to be used for communication between systems. Either ssh or rsh
should be preconfigured so that you can execute the commands without being
prompted for passwords or confirmations.
-ssh
Drops the repository database.
-o dropdb
Verifies the status of the database and database server.
-o dbstatus
Stops the database server.
-o stopserver
Starts the database server.
-o startserver
Reports the database server status.
-o serverstatus
Detaches the repository database from the database server.
-o stopdb
Attaches the repository database to the database server.
-o startdb
To create and configure the repository database
1. Run the sfua_db_config script:
# /opt/VRTSdbcom/bin/sfua_db_config
2. The following is an example of configuring SF Oracle RAC:
Welcome to the SFORA configuration script.
This script creates repository for standalone and HA configuration.
Please create a Veritas File System on a Veritas Volume and mount it,
before starting configuration using this script. This mount point will
be used to store repository. The following is required to configure
$prod repository for HA solution:
* A mount point of already mounted Veritas Volume on a shared storage, with Veritas File system.
