Unable to acquire IPCONN
A problem can occur if the system cannot acquire an IPCONN.
The following message appears in the CICS® Transaction Server log, where nnnn is the CICS server name:
DFHIS1011 CICS_server_name Unable to acquire IPCONN IPCONN_name. An EXCEPTION response to the capability exchange was received, reason=SECURITY_VIOLATION
The IPCONN definition is not configured to use SSL and CICS Transaction Gateway, and the resource adapter is running on a different sysplex to CICS.
If you are using a resource adapter in local mode, configure it to use SSL. Put the Gateway on the same sysplex as the CICS server. For more information see Configurations that support identity propagation.
