DBOPENfunctionality opens all available databanks in a system.
As each databank is opened, the integrity is checked and any transactions that were interrupted by the abnormal close are completed. (The integrity check is always performed when opening a databank that has not been closed normally.)
The checks performed when an abnormally closed databank is opened may take some time, particularly if the databank is large. Running
DBOPENmeans that the checks are performed at a time determined by the system administrator, rather than a time determined by application programs. As a result, users will always have fast access to all databanks.
The databanks are opened in a randomly determined order. Running several
DBOPENsessions in parallel may speed up the checking process for the database as a whole.
