Is it possible to monitor DB2 as a source(OS-AIX) and Oracle as a Target(OS-Linux) using OEM12c Plugin to monitor the golden gate.Please let us know.
Think this is a bit of a mixed question between OEM and GG. To answer your question, it is yes.
The OEM agent plug-ins are available for DB2, Oracle and GG. Setup of the GG plug-in would be the same on AIX as on any other platform.
