1  ATTACH
   Attaches RdbALTER to a database, putting an exclusive update lock
   on the database. No other user can access the database while the
   RdbALTER ATTACH command is in effect.

   The database specified by the root-file-spec parameter is
   attached to RdbALTER. Then you can alter the pages of its
   storage area files. Area 1, page 1 of the database is fetched
   automatically and remains the current page until you issue an
   AREA . . . PAGE command.
 

2  Description
   If the RMU Alter command includes a root-file-spec parameter, the
   database to which this root-file-spec refers is attached to as
   part of the RdbALTER startup. In this case, the ATTACH command is
   unnecessary. Otherwise, no commands changing database pages are
   allowed until an ATTACH command naming that database is issued.

   You can use the ATTACH command to attach to only one database at
   a time. Before invoking another database for altering, you must
   use the DETACH command to detach from the current database. See
   the help entry for the DETACH command for more information.
