*   CZ710.T07 DB-EZReorg Tech Note                    February 1998 *

*                                                                   *

*   KEYWORDS: PROCESS=REORG/INDEX/RSTU                              *

*                                                                   *

*   Description: DB-EZReorg can rollforward the updates after       *

*                a database reorganisation consisting of a          *

*                combination of a restructure, an unload/reload     *

*                or an index rebuild.  This Tech Note describes     *

*                the PROCESS= parameters required in each case.     *

*                                                                   *

*                                                                   *

*   DB-EZReorg can carry out rollforward operations after a         *

*   database unload/reload, an index rebuild or a database          *

*   resructure.  This is controlled by the PROCESS= parameter.      *

*   The three possible values for this parameter are REORG, INDEX   *

*   or RSTU and they are described in the manual.                   *

*                                                                   *

*   It is perfectly acceptable to code this parameter more than     *

*   once and this is required if the rollforward is to follow a     *

*   combination of reorganisation methods.  The rules for which     *

*   parameters to use are:                                          *

*                                                                   *

*           If an unload/reload has been carried out, there will    *

*           be a file of old/new dbkeys and PROCESS=REORG is        *

*           required.                                               *

*                                                                   *

*           If a retructure has been done, then there will be an    *

*           RSTT table and PROCESS=RSTU is required.                *

*                                                                   *

*           When an index rebuild in done, there will be no         *

*           old/new dbkeys file. In this case, code PROCESS=INDEX   *

*           to tell DB-EZReorg not to expect one.                   *

*                                                                   *

*           If PROCESS=REORG is coded, then PROCESS=INDEX is not    *

*           required.                                               *

*                                                                   *

*   Valid combinations therefore are:                               *

*                                                                   *

*                     PROCESS=REORG                                 *

*                     PROCESS=RSTU                                  *

*                                                                   *

*                     PROCESS=INDEX                                 *

*                     PROCESS=RSTU                                  *

*                                                                   *

*   All three are never required.                                   *

*                                                                   *
