Problem:

Added ISC connection which defines a connection to a mainframe CICS region (via MFA) to an MFE CICS region. When trying to start the region, the messages:

TXCS1101W CCI error: CCITC32-0016E Cannot find CCITCP2 - CCITCP cannot be used without a CCITCP2 process. 14:14:59

TXCS1105S TX CCI gateway failed to initialize, reason = 0009 14:14:59

appear and the region terminates.

Resolution:

The environment variable CCITCP2 has been set, causing MFE to search for a CCITCP2 process. A CCITCP2 process is not required for communications administered by MFA. Set CCITCP2 to a null value to resolve this issue.
