CICS Interface (DCI Prefix) Messages
CICS messages are produced by the CLIv2 interface to the IBM Customer Information Control System (CICS). DCI messages indicate that an error or warning was detected by the IBM CICS software. Each message starts with DCI and a four-digit number, followed by a description of the error or warning. Many of the DCI messages only provide status. For more information on CICS, see the IBM CICS Interface for Teradata Reference.
