You can create a policy that the CICSRequest node or message flow refers to at run time for connection information, instead of defining the connection properties on the node or the message flow. The advantage being that you can change the host name and performance values without needing to redeploy your message flow.
Use the CICS Connection policy to change the CICS Transaction Server for z/OS connection information for the CICSRequest node (see CICS Connection policy (CICSConnection)). The advantage of using a policy is that you can change the host name, performance, and security identity values without needing to redeploy your message flow.
You can use the CICS Connection policy to configure the CICSRequest node to use Secure Sockets Layer (SSL) protocol (see Securing the connection to CICS Transaction Server for z/OS by using SSL).
