VAXTPU SET(JOURNALING) — VMS 5.2

 SET(JOURNALING)

    Specifies how frequently records are written to the journal file.

 Syntax

    SET (JOURNALING, integer)
 Parameters

    integer    A number from 1 through 10.  The lower the value, the more
               frequently records are written to disk.

 Comments

    A value of 1 causes a record to be written for approximately every 10
    keys pressed; a value of 10, for every 125 keys.  If you are entering
    only text (rather than procedures bound to keys), the number of
    keystrokes included in a record is greater:

    o  For a value of 1, a record is written for approximately every 30 to
       35 keystrokes.

    o  For a value of 10, a record is written for approximately every 400
       keystrokes.

 Examples

    1.  SET (JOURNALING, 1);

        Specifies that journaling records are to be written as frequently
        as possible.  Thus, if the editing session is interrupted by a
        system failure, such as a communications break between your
        terminal and the computer, you are less likely to have lost any
        keystrokes.

    2.  SET (JOURNALING, 10);

        Specifies that journaling records are to be written as infrequently
        as possible.  This may improve performance, depending on your
        system configuration, but it increases the risk that some
        keystrokes will be lost if you have to use the journal file to
        recover your edits after a system failure.
