Accesing from Z/OS (Cobol-DB2) to Oracle database (UNIX)

I have a doubt about connection between two systems.

System1: Z/OS mainframe, Cobol/DB2.
System2: AIX server, Oracle 9i

In system1 I need data from system2 (Oracle database). I need data from three tables (three sqlís) one of the table has 5 millions records, and my sql will ask for 1 million (aprox). Iím thinking in using a Oracle client installed in system1 (Z/OS) that will connect with Oracle server in system2. Is that possible???,I have never done anything similar, is there any disadvantage in this architecture??, other options??. My other option is exchanging flat files with the data between the two systems. I donít like very much, because the applications may grow and need more data, and that will mean more filesÖ.

Any help, advice, will be greatly appreciated.
Thanks in advance

the best would be to install somewhere on luw platform a db2 and federation server
so from z/os you can connect to this db2 and to the nicknames for the oracle db and other
there is almost no possibility to select from oracle db2 data
db2 will have to take the start ...

That's not entirely correct. Oracle Transparent Gateway can connect to DRDA data sources, and you won't need an intermediate server for federation.
