AITI (CICS TS for z/OS® Version 3.1 only)

Explanation

A mirror transaction processing a START CHANNEL or LINK CHANNEL request has failed while trying to receive data from, or send data to, a connected CICS® system. Because a channel may include a considerable amount of data, many calls to terminal control may be required to transmit channel data. DFHMIRS calls program DFHAPCR to perform all the inter-system transmission of channel data. Terminal control has detected an error in one of these calls. The error could be a read time out, or a more serious error in the flows that prevented CICS from correctly processing the data.

System Action

The transaction is terminated. The mirror task is abnormally terminated with a CICS transaction dump.

User Response

If the error was a time out, determine why the remote region has not responded. Examine the trace to determine why the GETMAIN failed. If the CICS region was short on storage, take the necessary steps to correct this. If the region was not short on storage, you may need help from IBM® to resolve this problem.
