Introducing ALLBASE/REPLICATE
by Karen Poeschel
Commercial Systems Division
A new product, ALLBASE/REPLICATE, can be used with ALLBASE/SQL G.0 to
replicate a DBEnvironment on the same system or another system on an
existing network. ALLBASE/REPLICATE allows you to solve a number of
problems that involve replicating all or portions of one DBEnvironment
into another DBEnvironment.
In a replicate environment, one DBEnvironment is defined as a master DBE
and the other DBEnvironment is defined as a slave DBEnvironment. Running
the ALLBASE/REPLICATE application allows transactions that are committed
on the master DBEnvironment to be replicated on the slave DBEnvironment.
The transactions replicated can be for the whole master DBEnvironment
or a subset of tables of the master DBEnvironment. Using the
ALLBASE/REPLICATE application, you can solve problems such as:
* Maintaining a "standby" DBEnvironment in case the master DBE
becomes inaccessible.
* Improving the performance of the primary system by offloading some
read-only applications to one or more "shadow" systems.
* Performing database backups remotely.
The ALLBASE/REPLICATE product consists of an application and a call level
interface. If a custom solution is desired, the call level interface can
be used to develop a replicate application.
