Oracle Jinitiator is slow to initialize and users will need to wait while the application downloads its components and start. Or, Oracle Jinitiator times out while connecting to the appliance.
Use OnDemand Tunnel in the community where users will be using Jinitiator. OnDemand Tunnel is able to efficiently handle the large number of connection requests that Jinitiator will make to the back-end server.
If a timeout is seen, add an IP address resource for the Oracle server to the appliance and configure the Jinitiator application to connect to the server, through OnDemand Tunnel, by IP address instead of hostname.
