从DB2 z / OS到Oracle / Postgres的迁移：DB2 Connect替换

Question

In the context of a mainframe rehosting project (from z/OS to Linux), we are planning to migrate DB2 z/OS to Oracle.

Currently, several Windows applications uses DB2 connect DDF/DRDA to access to DB2 z/OS data (through ODBC, JDBC).

Will it be necessary to use Oracle Database Provider for DRDA for these applications ? Or can we simply use normal ODBC / JDBC Oracle drivers and adapt the code ?

Thanks.

Answer 1

You can use normal Oracle drivers (if you want your Windows odbc/jdbc applications) to access Oracle on Linux. Yes you may need to adapt some of the code and of course the connection strings. You don't need DB2-connect unless you want some applications to continue to use type-2 drivers to access DB2 on Z/OS.
