Configuring CIS load balancing
When you install the CIS software in an environment where the processing load will be distributed over multiple CIS machines, verify that all CIS servers being used for load balancing use the same Oracle credentials and tnsnames for the CIS and Clintrial databases.
In addition, if you use a hardware load-balancing machine to distribute transaction processing to different InForm Adapters, you must register the load balancing machine with CIS administration. For more information, see Registering an InForm Adapter.
