You can combine a series of commands in an operating system command file. IMSDBU also supports its own Runlist command files. These are similar to operating system command files but allow you to process a series of functions as a group. A combination of operating system commands and Runlist files provides a great deal of flexibility for automating repetitive functions.
The Rollback (ROLB) function does not require that you specify the database-name or the filename.
