Uniquely, the CICS®
VT solution means that you do not have to change
any of your existing application programs, but your data is still migrated to
DB2®.
Because you don't change your programs, the migration costs are reduced, but
more importantly your risk is substantially reduced.
By using CICS VT,
you have a single copy of the data in
DB2
without having to change any of your
existing legacy application programs. This means that the inherent problems
associated with the previously described options are eliminated, as follows:
- Only one copy of the data exists, so synchronization is not an
issue.
Your legacy programs and your end users can share the data.
- No changes to legacy programs are required. The degree of change
and therefore
the scale of the risk is reduced significantly.
- Local and disaster recovery procedures are simplified because
there is
one less data type to support.
- You can use standard tools, skills, and resources, and achieve
economies
of scale in your database administration area.
- Your data integrity is assured because it is under the control
of a DBMS.
As well as these benefits, your end users can have real-time
access to real-time data.
