  2. Journaling file system - Wikipedia

    en.wikipedia.org/wiki/Journaling_file_system

    If a crash occurs after step 1 and before step 2, there will be an orphaned inode and hence a storage leak; if a crash occurs between steps 2 and 3, then the blocks previously used by the file cannot be used for new files, effectively decreasing the storage capacity of the file system. Re-arranging the steps does not help, either.

  3. XFA - Wikipedia

    en.wikipedia.org/wiki/XFA

    XFA defines static forms (since XFA 2.0 and before) and dynamic forms (since XFA 2.1 or 2.2). In a static form the form’s appearance and layout is fixed, regardless of the field content. Any unfilled fields are present in the form. By default, static forms do not require re-rendering.

  4. JDBC driver - Wikipedia

    This differs from the type 4 driver in that the protocol conversion logic resides not at the client, but in the middle-tier. Like type 4 drivers, the type 3 driver is written entirely in Java. The same client-side JDBC driver may be used for multiple databases. It depends on the number of databases the middleware has been configured to support.

    XFS does not yet [25] provide direct support for snapshots, as it currently expects the snapshot process to be implemented by the volume manager. Taking a snapshot of an XFS filesystem involves temporarily halting I/O to the filesystem using the xfs_freeze utility, having the volume manager perform the actual snapshot, and then resuming I/O to ...

  6. Andrew File System - Wikipedia

    en.wikipedia.org/wiki/Andrew_File_System

    Re-establishing a callback involves a status check and does not require re-reading the file itself. A consequence of the file locking strategy is that AFS does not support large shared databases or record updating within files shared between client systems. This was a deliberate design decision based on the perceived needs of the university ...

    en.wikipedia.org/wiki/Archive_file

    Archive files are particularly useful in that they store file system data and metadata within the contents of a particular file, and thus can be stored on systems or sent over channels that do not support the file system in question, only file contents – examples include sending a directory structure over email, files with names unsupported on the target file system due to length or ...
