XDM DATABASE CLONING
SETUP A PRE-PRODUCTION
ENVIRONMENT
Setting up a clone of the production environment is a daunting task. A key component of that
environment is the data (DB2, VSAM,..) which must be refreshed regularly (daily, weekly, monthly,..)
depending on the company requirements. The data used in creating this production image can be
used to supply fresh data for other test and development testbeds. The DB2 data can be passed on
to Linux, Unix, Windows, Oracle or MSSQL, so that these alternate platforms can also support the
proper testing, development or enhancement of existing applications. Consistent production data
is needed in order to populate a pre-production or staging environment for QA, User Acceptance,
Stress Testing and to refresh application playpens. Obtaining this data should not entail stopping
production. XDM-DC has been designed from the ground up with the latest technology to satisfy
the most demanding of shops. It obtains DB2 data without needing to quiesce DB2; it can create a
clone of the data; it can distribute the data to other platforms; it can do almost any reasonable task
requested by a systems programmer or DBA
Commercial Benefits
• Cost-efficient creation of
• pre-production environments
• Heterogeneous systems copies
• to a single point in time
• Reduction of manual work
• Flexible supply of fresh test data
• for distribution
• No need to wait for cloning
• time slot

Create a clone
A clone is an independent, consistent, 1:1 copy of a
database at a fixed point in time. XDM-DC is able to
copy data in-flight throughout the cloning process.
The source database does not need be stopped. Any
changes, which occurred in the active source system
during the cloning process (for example with INSERT,
UPDATE, DELETE-statements), are applied after the
process to update the clone to a fixed point in time. In
order to achieve consistency, XDM-DC uses the database
logs of the source system. The point in time at which both
databases are to be identical is defined by the user, or
automated by XDM-DC. After the refresh of all open
transactions, a fully functional and consistent clone database is ready to be used.

Clone a heterogeneous database system
If the source system consists of multiple databases which
are interconnected with different DBMS, the creation of
a consistent clone is not possible without a considerable
amount of effort. A standard clone of these databases
would result in an inconsistent system. XDM-DC is able
to handle databases from different DBMS’s, provides
parallel cloning and refreshes the relevant logs. An
identical target system including all relations between
databases can be established for a desired point in time.

XDM DATABASE CLONING – SETUP A PRE-PRODUCTION
Pre-production as a basis
XDM-DC is optimally designed for the creation of preproduction or staging environments. It is a data source for
release, acceptance- and regression tests. It is often used
for making subset copies at the table or dataset level. The
clone completely segregates the production data from the
test data. If required, XDM-DC is able to anonymize the
data during the cloning process in order to meet regulatory
compliance rules.
Features
• Supply production data
• for test data management
• Minimal impact on production
• Automated synchronization of
• heterogeneous systems
• Automated workflow for the
• supply of test data
• Decoupling of production and
• test data

Decoupling of production and test
Production no longer needs to be stopped to allow for
consistent data to be extracted. XDM-DC is able to provide
clones “on demand” without having to wait for an open
window in production. This has substantial benefits for
testers and developers. If required, XDM-DC´s users can
receive email notifications with all relevant information
concerning status, results and working steps of cloning
tasks.
Working with fast hardware components
When fast hardware components, like Flashcopy1,
EMC Timefinder, HDS Shadowimage, or SnapShot,
are available, XDM-DC utilizes them and creates the
fastest possible pre-production clones. Of course, data
consistency and 24x7 operations are not compromised.
