[AXIS2] Replication For High Availability

[kensky <ke...@googlemail.com>]

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

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.

Regards
Kensky

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 ?

I believe sandesha is what you're after - just hit a 1.0 version for axis2.
