I have three disks. OCR, DATA and FRA.

What is the function of OCR? I understand DATA is where all the database files are kept together with the temp files and redo logs and FRA is where archive logs and backups are kept but OCR is what I want to know.

CodePudding user response：

OCR stands for Oracle Cluster Registry, which is the place where Oracle cluster processes store and manipulate data related to the cluster. And as the question itself says, in ASM these are not single disks put usually a bunch of disks or disk partitions.
