Datafiles can exist on four device types: local file systems, clustered file systems, raw devices, and ASM disk groups: Files on a file local system These are the simplest datafiles; they exist as normal operating system files in a directory structure on disks directly accessible to the computer running the instance On a PC running Windows or Linux, these could be internal IDE or SATA drives On more sophisticated hardware, they would usually be SCSI disks, or external drives Files on a clustered file system A clustered file system is usually created on external disks, mounted concurrently on more than one computer The clustered file system mediates access to the disks from processes running on all the computers in the cluster Using clustered file systems is one way of implementing RAC: the database must reside on disks accessible to all the instances that are going to open it Clustered file systems can be bought from operating system vendors, or Oracle Corporation s OCFS (Oracle Clustered File System) is an excellent alternative OCFS was first written for Linux and Windows (for which there were no proper clustered file systems) and bundled with database release 9i; with 10g it was ported to all the other mainstream operating systems Files on raw devices It is possible to create datafiles on disks with no file system at all This is still supported but is really only a historical anomaly In the bad old days before clustered file systems (or ASM) existed, raw devices were the only way to implement a Parallel Server database Parallel Server itself was replaced with RAC in database release 9i Files on ASM devices ASM is Automatic Storage Management, a facility introduced with database release 10g This is an alternative to file system based datafile storage and covered in detail in 20 TIP Some people claim that raw devices give the best performance With contemporary disk and file system technology, this is almost certainly not true And even if it were true, they are so awkward to manage that no sane DBA wants to use them ASM is tested in detail in the second OCP examination, but an understanding of what it can do is expected for the first examination ASM is a logical volume manager provided by Oracle and bundled with the database The general idea is that you take a bunch of raw disks, give them to Oracle, and let Oracle get on with it Your system administrators need not worry about creating file systems at all A logical volume manager provided by the operating system, or perhaps by a third party such as Veritas, will take a set of physical volumes and present them to the operating system as logical volumes The physical volumes could be complete disks, or they could be partitions of disks The logical volumes will look to application software like disks,.
