Switch_Journal Changes the currently active .aij file to the next available .aij file in a fixed-size after-image journaling configuration. In an extensible journal file configuration, the Switch_Journal qualifier has no effect and is ignored if specified. The Switch_Journal qualifier is useful for forcing a switch to an .aij file on another disk when you want to perform maintenance on the disk containing the currently active journal file. You cannot specify the Switch_Journal qualifier and the Enable or the Disable qualifier on the same command line. In addition, after-image journaling must be enabled when you issue the Switch_ Journal qualifier. It is seldom necessary to specify this option because normally a switch occurs automatically.
