How to make connection to the database using teiid VDB in mod_cluster?
I have created cluster using one master and one slave.
I am trying to make a connection with the help of jboss application user and not admin user, In server logs I can see VDB gets activated when I deployed it using admin user but when I am trying to make connection it throws an exception
org.teiid.jdbc.TeiidSQLException: TEIID20020 Error establishing socket to host and port: <IP_Address>:31000. Reason: Connection refused: connect
and code line is:
connection = DriverManager.getConnection("jdbc:teiid:" + VDBName + "@mm://" + IPAddress + ":" + port + ";", userName, password);
After this exception when I checked server logs on master and I found teiid instance acquire the port 31250 because of port-offset was set to 250 and on slave it was 31450, So I changed my configuration and 31250 is set to access teiid and it worked. Now Its time to check whether I can access VDB when master is not running so I shutdown it and it failed to connect to the database.
Later I created a demo dynamic web application zclusterDemo and deployed it on a master just to check if my configurations are correct it gets deployed on both the node and worked as well when master is completely down.
here it is how mod_cluster-manager page looks like, here I can see zclusterDemo application but not any VDB.
