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.
