Hie Deepal, Thanks for response. In my scenario its an axis2 web application and on back I am using native xml database. From your reply I can assume axis2 provides high availability feature, but what if embedded database crashes, coz it provides its own mechanism of replication and master election mechanism.
I think one solution could be to handle the database and webservice replica by tomcat cluster. e.g we have A,B and C nodes each with axis and db. Firstly if anything goes wrong with webservices then presumably any tomcat cluster will take up as master. Secondly if xml db crashes where and how the subsequent requests transferred to the replica? And, this native xml db provides its own replication mechanism. For this application I want to use passive(with state) replication. Lastly, does axis2 provide any security mechanism for intermediate messaging between clients and master in the course of replication.

Hi Kensky ; I did some work sometimes ago to support FT for Axis1 (http://www-128.ibm.com/developerworks/webservices/library/ws-faws/). Axis2 to has all the guts to support FT so you can use same kind of approach for Axis2 too. I honestly know to have better FT one part missing in Axis2 , that is it does not save the run time when it shout down, but still you can have FT with Axis2 w,o having any problem. btw which FT scenario you are going to use , is that Active or passive ? kensky wrote: >Hie, >In my application I want to provide high availability and fault tolerance of >web services deployed on axis2 and tomcat. > >Is it possible to have this featrue using Axis2 with Tomcat. if so how? > >Thanks and Regards >kensky >-- >View this message in context: http://www.nabble.com/-AXIS2-Replication-For-High-Availability-t1596410.html#a4331183 >Sent from the Axis - User forum at Nabble.com. > > > > > -- Thanks, Deepal ................................................................ ~Future is Open~
