The Question is:
I have an application running on VAX4705A which uses ACMS and cobol programs
using TDMS forms.The backend database is Oracle Rdb V7.0-12 which is also at
same node . We want to shift out the databse to a alpha system so I just
wanted to check is it poss
ible to keep database on alpha and my exisitng programs on VAX still access
the database. If its possible then what modification we may need to do in our
application redesign.
The Answer is :
For COBOL, you should review the Compatibility Appendix in the
Compaq COBOL V2.7 User Manual for Alpha. This manual has
information on many issues that have come up over the last 9 years
in migrations from VAX to Alpha of COBOL applications.
In particular, review the material on alignment (/ALIGN,
/ALIGN=PADDING, alignment directives). COBOL data alignment control
has been used by some customers to help in the migration of COBOL
DECforms and ACMS applications from VAX to Alpha.
For Oracle Rdb questions and statements of support, please contact
Oracle Rdb support. Having said that, current and compatible versions
of Oracle Rdb can be used and can be accessed entirely in parallel
across all nodes of a cluster, regardless of the architecture -- this
works across all architectures supported by Oracle Rdb.
