I am using following syntax for connecting using JDBC Driver
jdbc:informix-sqli://192.168.0.16:9991/demo_db:informixserver=oltp

Please let me know that where i am wrong, and how i could connect my application with the connection manager, so that i could test the HA feature.

Thanks in advance for your anticipation.

Omer Saeed Khan
