Look what the document "Exadata Software and Hardware Support Lifecycle (Doc ID 1570460.1)" says;
Exadata supports multiple Oracle database versions on a single machine. For example a customer might run an 188.8.131.52 database, an 184.108.40.206 database, and a 220.127.116.11 database at the same time on a single Exadata configuration.
Maintain only a few active Oracle Home versions, because a proliferation of different database
versions causes additional maintenance complexity. Also remember that the Oracle Grid Infrastructure
software version must be the same as, or later than, the highest Oracle Database software version.
thx for fast reply also i want to ask another question, we are using goldengate(version is 18.104.22.168).
Normally we use that goldengate on rac machine which is 22.214.171.124 version database (but its not on the exadata) hence we must move this goldengate to exadata too.
In summary,we ll use 126.96.36.199 database and 188.8.131.52 database on same exadata and 184.108.40.206 database has to use goldengate 220.127.116.11,is that possible?
Or should we upgrade goldengate
i will write that architectr about goldengate but also i want to know if we migrate this 18.104.22.168 database to this exadata machine should we use exadata compression for this database ?
is it(compression) necessary or optional?
The Integrated Capture mechanism relies on Oracle’s internal log parsing and processing to capture DML transactions. By moving closer to the Oracle Database engine, Oracle GoldenGate can take advantage of new Oracle Database features and functionality more quickly.
For example, this new mechanism allows GoldenGate to support advanced features such as compression. Integrated Capture provides support for all flavors of Oracle compression, including hybrid columnar compression (EHCC) on Exadata, where as our “Classic” capture would not.
