ALLBASE/SQL Reference Manual

BEGIN ARCHIVE 

If you do not have TURBO STORE and must do a static backup of your
DBEnvironment, you can use the BEGIN ARCHIVE statement in conjunction
with and immediately prior to the COMMIT ARCHIVE statement to start a new
archive log file before a DBEnvironment is backed up.  However, if you
have TURBO STORE, the recommended approach to initiate archive logging is
to use the SQLUtil STOREONLINE command, or to use the ARCHIVE option with
the START DBE NEWLOG statement.

Scope 

ISQL or Application Programs

SQL Syntax 

BEGIN ARCHIVE

Description 

   *   You can turn archive mode off only by using the START DBE NEWLOG
       statement.

   *   A backup copy of a DBEnvironment and an archive log file can be
       used for rollforward recovery when database files are physically
       damaged.  In this type of recovery, you load a backup copy of the
       DBEnvironment, then issue the SQLUtil SETUPRECOVERY, RECOVERLOG,
       and ENDRECOVERY commands.  You may also need to use RESCUELOG.

   *   Use the following method to create a new archive log and a static
       backup of the DBEnvironment:

          *   Issue the BEGIN ARCHIVE statement, then the COMMIT ARCHIVE
              statement, to write an archive record in the rollforward
              log.  The archive record indicates the point from which
              rollforward recovery can begin.

          *   Use the SQLUtil STORE command to make a static backup copy
              of the DBEnvironment.  The DBEnvironment must be stopped
              and remain stopped while you are making the static backup
              copy if you are using STORE. This procedure does not turn
              the archive flag in the DBECon file on or off.  You cannot
              use STORE from an application program, since it is an
              SQLUtil command.

Refer to the ALLBASE/SQL Database Administration Guide for detailed
backup and recovery procedures and recommended practices.

Authorization 

You must have DBA authority to use this statement.

Example 

       A single-user DBE session is established.

     START DBE 'PartsDBE.SomeGrp.SomeAcct'


NOTE Always use these two statements together in sequence.
BEGIN ARCHIVE COMMIT ARCHIVE ALLBASE/SQL creates an archive record. The DBEnvironment is shut down. Then the SQLUtil STORE command is used to make an archival copy of the DBEnvironment. STOP DBE
