<font face="Verdana,Arial,Helvetica,sans-serif" size="2"><div>Thank you all for your \
comments on this.<br></div><div><br></div><div>We will try to follow the H2 approach, \
but we are facing another problem regarding the communication between Traffic Manager \
instances. As we are defining the service in DC/OS as one service, there is no good \
way to tell the node to replicate the messages received from the APIGW only to \
the other TM instances. We have the idea to extend the jndi.properties parsing, to \
allow the use of the marathon API to get information about the other instances \
present in the service group. Could you give us a pointer to where we have to extend \
this to add the functionality?</div><div><br></div><div>Thank you \

may know, we are implementing WSO2 in El Corte Ingles, and we are trying to fit \
Traffic Manager in our architecture, based on DC/OS and containers. We would like to \
know which approach you think it may be better for the Traffic Manager component. As \
we are in a PaaS system, we would like to be able to scale this system out without \
problems. </div><div><br></div><div>a) It is our understanding that we have to \
create a different database schema for every TM instance that we run. We would like \
to know if it is possible to run this without having to create a new schema for every \
component (that is, share the same schema). If we create a new schema, that would \
force us to differentiate the component at DC/OS level, giving them different \
configurations for different Traffic Manager \
instances. </div></font></blockquote><blockquote class="gmail_quote" \

possible.</div></font></blockquote><div>Message Broker(MB) instance running in TM \
required MB_STORE data source which shouldn't shared with TM instance.It's Ok to have \
H2 database for it. But by default, MB writes all messages first to the database. \
Enable HA in TM is same as enabling HA in CEP (<a \

The additional JMS related changes need to be configured to communicate throttle \
decisions to the gateway nodes.</div><blockquote class="gmail_quote" \
