Double-Take Share is an easy to use real-time, multi-platform
change data replication tool.

Double-Take Share replicates columns in changed rows in real
time between MS SQL Server, DB2/400, DB2/UDB, DB2/zOS,
Oracle, Informix and Teradata.
Data columns can be easily mapped and transformed while
replicated (no programming required).
This tool is typically used by development to greatly simplify
internal projects that require real-time movement of data.

Manipulating Data
Target Column Expressions
Fast way to specify simple and medium complexity data
manipulations
Join Tables
It’s possible to join tables together and build a
new table on the target.
Eg. Join the invoice header table with the
customer master table to get address columns
Replication Scripting Language (RSL)
All data manipulations are stored in a easy to read
scripting language, which can be exported, edited
and imported for advanced manipulations by
power users. Also a big time saver in
sophisticated enterprise environments with lots of
tables.

Double-Take Share Components & Monitoring
EDMM
All data replication rules including data mappings and
data manipulations are stored internally using a
scripting language in an Enterprise Data Movement
Model.
MonCon
The monitoring and control interface is one of several
ways to monitor the status of replication in real time.
MonCon lets you do this locally through a graphical
monitor. There is also WebMonCon that allows
monitoring through a web browser.
