When you have multiple JBoss AS instances installed with Teiid and
clustered, do want use this setup to make Teiid highly available? Then
there are 2 solutions
1) Add the multiple host:port combination in the JDBC connection URL.
See Client Developer's Guide.
2) You can do software based external cluster configuration using
HAProxy, see this blog post http://goo.gl/IPzU1
Thank you Jermy for
