The client application receives an ECI_ERR_NO_CICS error when attempting to send a request to CICS over an IPIC connection.
An ECI_ERR_NO_CICS error occurs and the following message is written to the CICS Transaction Gateway log:
CTG8431E Handshake failure for IPIC connection to CICS server CICSIPIC response code=ISCER_EXCEPTION, reason=AUTOINSTALL_FAILED [1]
The following message is written to the CICS Transaction Server log:
DFHIS3001 11/20/2009 11:58:08 <CICS_server_name> IPCONN autoinstall rejected after a connection request was received on TCPIPSERVICE <TCPIPService_name> from host ipaddress because the TCPIPSERVICE has URM(NO)
The TCPIPService is configured to use predefined IPCONNs exclusively but a matching IPCONN definition was not found.
Check the IPCONN definitions installed on CICS; look to see if one exists that has an APPLID that matches the APPLID and APPLID qualifier of the Gateway daemon. For more information see IPIC server connections.
Alternatively
you can enable autoinstall on the TCPIPService. For more information
see CICS Transaction Server Information Centers Library.
