Description of the illustration strep067.eps
This illustration shows the details of the mult1.example.com
Oracle Streams configuration, including the following mechanisms:
-
One queue that is used by the capture process, propagations, and apply processes.
-
A capture process that captures changes in the redo log and converts relevant changes into LCRs, which it enqueues. The capture process captures a change only if its tag is
NULL
. -
One apply process that applies changes from
mult2.example.com
and another apply process that applies changes frommult3.example.com
. Both of these apply processes dequeue changes from the same queue. Any apply change frommult2.example.com
andmult3.example.com
has a tag of'00'
in the redo log. -
One propagation to propagate locally captured LCRs to
mult2.example.com
and another propagation to propagate locally captured LCRs tomult3.example.com
