Oracle Database Search Results: voting disk

High availability configurations have redundant hardware and software that maintain operations by avoiding single points of failure.

You can dynamically add and remove voting disks after installing Oracle RAC.

Oracle Clusterware includes two important components: the voting disk and the OCR.

After your Oracle Clusterware installation is complete, and after you are sure that your system is functioning properly, make a backup of the contents of the voting disk using ocopy.exe which resides on the Oracle Database home.

A file that manages information about node membership.

After your Oracle Database 11g with Oracle RAC installation is complete, and after you are sure that your system is functioning properly, make a backup of the contents of the voting disk.

Because the node membership information does not usually change, you do not need to back up the voting disk every day.

If a voting disk is damaged, and no longer usable by Oracle Clusterware, you can recover the voting disk if you have a backup file.

Oracle recommends that you back up your voting disk after the initial cluster creation and after you complete any node addition or deletion procedures.

To restore the backup of your voting disk, issue the dd or ocopy command for Linux and UNIX systems or for Windows systems respectively.
