inode list
An inode is an on-disk data structure in the file system that defines everything about the file, except
its name. Inodes contain information such as user and group ownership, access mode (permissions),
access time, file size, file type, and the block map for the data contents of the file. Each inode is
identified by a unique inode number in the file system where it resides. The inode number is used to
find the inode in the inode list for the file system. The inode list is a series of inodes. There is one
inode in the list for every file in the file system.
instance
When you start a database, a system global area (SGA) is allocated and the Oracle processes are
started. The SGA is the area of memory used for database information shared by all database users.
The Oracle processes and the SGA create what is called an Oracle instance.
intent logging
A logging scheme that records pending changes to a file system structure. These changes are
recorded in an intent log.
interrupt key
A way to end or break out of any operation and return to the system prompt by pressing Ctrl-C.
JFS
Journaled File System, the HP-UX name for a light version of the VERITAS File System that
includes only the journaling feature.
kilobyte
One thousand bytes. For technical specifications, it refers to 1,024 bytes. In general usage, it
sometimes refers to an even one thousand bytes. Also KB, Kbyte and K-byte.
large file
A file more than two gigabytes in size. An operating system that uses a 32-bit signed integer to
address file contents will not support large files; however, the Version 4 disk layout feature of VxFS
supports file sizes of up to two terabytes.
large file system
A file system more than two gigabytes in size. VxFS, in conjunction with VxVM, supports large
file systems.
