The Oracle Cluster File System (OCFS, in its second version OCFS2) is a shared disk file system developed by Oracle Corporation and released under the GNU General Public License. The first version of OCFS was developed with the main focus to accommodate Oracle's database management system that used cluster computing .
[6] btrfs-check is still available to check for suspected problems in filesystem structure (e.g. when a software bug or hardware issue is suspected). Independent of checking the file system structure, modern file systems may offer a data scrubbing tool to check for silent corruption in stored data against a mirror or a checksum .
Starting from Oracle database 11g, iSqlplus (web based) and sqlplus GUI no longer ship with Oracle database software. [7] The command-line SQL Plus interface continues in use, mostly [ citation needed ] for non-interactive scripting or for administrative purposes.
cksum is a command in Unix and Unix-like operating systems that generates a checksum value for a file or stream of data. The cksum command reads each file given in its arguments, or standard input if no arguments are provided, and outputs the file's 32-bit cyclic redundancy check (CRC) checksum and byte count. [1]
ZFS (previously Zettabyte File System) is a file system with volume management capabilities. It began as part of the Sun Microsystems Solaris operating system in 2001. Large parts of Solaris, including ZFS, were published under an open source license as OpenSolaris for around 5 years from 2005 before being placed under a closed source license when Oracle Corporation acquired Sun in 2009–2010.
The reason for some limits of ext2 are the file format of the data and the operating system's kernel. Mostly these factors will be determined once when the file system is built. They depend on the block size and the ratio of the number of blocks and inodes. [citation needed] In Linux the block size is limited by the architecture page size.
All Cerner Millennium health information technology software uses CCL/Discern Explorer to select from, insert into, update into and delete from a Cerner Millennium database and allows a programmer to fetch data from an Oracle database and display it as the user wants to see. With features like Record Structure and subroutines it allows a user ...
The total size of the file system in 512-byte units. The exact meaning of this figure is implementation-defined, but should include <space used>, <space free>, plus any space reserved by the system not normally available to a user. <space used> The total amount of space allocated to existing files in the file system, in 512-byte units. <space free>
