NAME
       emprepsync - performs replication synchronization

SYNOPSIS
       emprepsync  [-fv]  replicate_database  replicate_table  [ replicate_ta-
       ble]...



DESCRIPTION
       emprepsync is the Replication Synchronization  Utility  which  synchro-
       nizes  the  data  of  one  or more replicate tables indicated by repli-
       cate_table in replicate_database, with the data of their  corresponding
       Replication  Master  Tables. More than one replicate_table belonging to
       the same replicate_database can  be  synchronized  using  one  call  of
       emprepsync Replication Synchronization Utility.

       For  each  replicate  table replicate_table, there is defined a list of
       Replication Master Entries.  Each  Replication  Master  Entry  contains
       information to access a candidate Replication Master Table.  emprepsync
       "chooses" a Replication Master Entry that  is  "enabled"  and  has  the
       smallest  Replication  Master Order, It then attempts to connect to the
       Replication Master Server assigned to the "chosen"  Replication  Master
       Table.   If  a connection with the Replication Master Server can not be
       established, emprepsync will try to choose another  Replication  Master
       Table  which  has a larger Replication Master Order until either a suc-
       cessful connection is established, or no other Replication Master Table
       is  remained  in the list to be tried. If no connection with any of the
       Replication Master Tables in Replication Master List of replicate_table
       can be established, emprepsync exits with an error message.

       After  the  first successful connection to a Replication Master Server,
       emprepsync will try to  synchronize  replicate_table  with  the  chosen
       Replication  Master  Table.  If this synchronization fails, the partial
       effects of the synchronization will not be reflected  to  replicate_ta-
       ble, and the other Replication Master Tables will not be tried.

       -v     This option causes emprepsync to show verbose on synchronization
              progress status, so that the user would know  whether  the  syn-
              chronization is in progress or not.

       -f     This  option  forces  emprepsync  to synchronize replicate_table
              with the Replication Master Table accessed by  the  successfully
              connected  Replication Master Server assigned by chosen Replica-
              tion Master Entry, even if the contents of  replicate_table  are
              more  recent  than  that  of its Replication Master Table.  Note
              that [-f] option works only  when  Current  Master  Table  Start
              Timestamp  (CMTS)  of  replicate_table  is  equal to CMTS of its
              Replication Master Table participating in the  Replication  Syn-
              chronization.
