You might use Solaris Volume Manager metadevices as devices for the shared file systems. In this situation, ensure that the metaset and its metadevices are created and available on all nodes before configuring the shared file systems.
Ensure that the Sun StorEdge QFS software is installed on all nodes where Sun Cluster Support for Oracle RAC is to run.
For information about how to install Sun StorEdge QFS, see Sun StorEdge QFS Installation and Upgrade Guide, Version 4, Update 5.
Ensure that each Sun StorEdge QFS shared file system is correctly created for use with Sun Cluster Support for Oracle RAC.
For information about how to create a Sun StorEdge QFS file system, see Sun StorEdge QFS Configuration and Administration Guide, Version 4, Update 5.
For each Sun StorEdge QFS shared file system, set the correct mount options for the types of Oracle files that the file system is to store.
For the file system that contains binary files, configuration files, alert files, and trace files, use the default mount options.
For the file systems that contain data files, control files, online redo log files, and archived redo log files, set the mount options as follows:
In the /etc/opt/SUNWsamfs/samfs.cmd file or the /etc/vfstab file, set the following options:
fs=fs-name stripe=width sync_meta=1 mh_write qwrite forcedirectio nstreams=1024 rdlease=300Set this value for optimum performance. wrlease=300Set this value for optimum performance. aplease=300Set this value for optimum performance.
Specifies the name that uniquely identifies the file system.
Specifies the required stripe width for devices in the file system. The required stripe width is a multiple of the file system's disk allocation unit (DAU). width must be an integer that is greater than or equal to 1.
Ensure that settings in the /etc/vfstab file do not conflict with settings in the /etc/opt/SUNWsamfs/samfs.cmd file. Settings in the /etc/vfstab file override settings in the /etc/opt/SUNWsamfs/samfs.cmd file.
Mount each Sun StorEdge QFS shared file system that you are using for Oracle files.
# mount mount-point |
Specifies the mount point of the file system that you are mounting.
Change the ownership of each file system that you are using for Oracle files as follows:
Owner: the database administrator (DBA) user
Group: the DBA group
The DBA user and the DBA group are created as explained in How to Create the DBA Group and the DBA User Accounts.
# chown user-name:group-name mount-point |
Specifies the user name of the DBA user. This user is normally named oracle.
Specifies the name of the DBA group. This group is normally named dba.
Specifies the mount point of the file system whose ownership you are changing.
Grant to the owner of each file system whose ownership you changed in Step 4 read access and write access to the file system.
# chmod u+rw mount-point |
Specifies the mount point of the file system to whose owner you are granting read access and write access.
Ensure that all other storage management schemes that you are using for Oracle files are installed.
After all storage management schemes that you are using for Oracle files are installed, go to Registering and Configuring the RAC Framework Resource Group.
