Note that any filesystem issues are need to be resolved by the Linux vendor. – Single node: Any filesystem that is supported by the Linux vendor. In summary, the recommended filesystems are: – OCFS2 is a general-purpose file system that can be used for shared Oracle home installations making management of Oracle Real Application Cluster (RAC) installations even easier. It is an extent based, POSIX compliant file system. OCFS volumes can span one shared disk or multiple shared disks for redundancy and performance enhancements (Note 224586.1).OCFS2 is the next generation of the Oracle Cluster File System for Linux. OCFS eliminates the requirement for Oracle database files to be linked to logical drivers. – Oracle Cluster File System (OCFS) is a shared file system designed specifically for Oracle Real Application Cluster (RAC). ext3 is the detault filesystem for RHE元 and 4. ext3 is simply the enhanced ext2 filesystem having journaling feature. ext2 was the default file system under the 2.2 kernel. – The ext2 and ext3 file systems are robust and fully supported. There are various file systems available for Linux OS: Counter examples are simple NFS, which lacks acknowledge and VFAT, which lacks file permissions.
To be acceptable for database usage, the file system must support certain minimum functions such as write acknowledgement, write-through cache and file permissions. The current support includes ext2, ext3 and NFS-based storage systems (e.g. If the problem does not reproduce on a certified filesystem, the specific filesystem / O/S vendor should be engaged for resolution. When a problem is encontered, if a non-supported filesystem is being used for Oracle data, control and redo log files, Oracle will try to reproduce the problem on a supported and certified filesystem. On different Linux distributions, Oracle might choose to have certifications on different filesystems. Oracle generally does not certify file systems and does certify operating systems, but Linux is a specific case. Your choice of which one to use then becomes based on supportability, reliability, security and performance. VFAT, ext2, ext3 and Reiser file systems can co-exist on the same Linux system, along with several other file systems and raw partitions (Note 224302.1 – Raw Devices on RedHat Advanced Server – FAQ). File systems can be defined and built on a partition basis. One of the most interesting features of the Linux OS is its support for multiple and various file systems. Metalink note 236826.1 states: - Begin Quote. Metalink has several notes on what file systems can/shall be used for oracle on linux.
#Does systemrescuecd supportt ext2 free
My opinion might not be solely true and you are free to develop your own standards. In the following i am blogging my thoughts and recommendations on partition/storage design on the linux operating sytsem for oracle. Partition recommendations for Oracle on LinuxĮvery system engineer or even every DBA comes along the following question from time to time: “How do i arrange my partitions for using oracle on linux?”
