The following list describes the process for implicit attachment as illustrated in the figure above:
- The ATMI service makes a request to the service
TRN1DATA
, which is advertised as a remote service in theDMCONFIG
file. It is a DPL request to a program namedSVC1
in the CICS/ESA region. - The first four characters of the remote service tag name
(
TRN1
) are extracted and passed to the CICS/ESA region as the invokingTRANSID
. No CICS/ESA resource definition for theTRANSID
is required in the region. - The mirror transaction CSMI is attached in the CICS/ESA region,
starting the mirror program
DFHMIRS
. The program performs the DTP requests for the service. - The mirror program now attaches the invoking
TRANSID
(TRN1
) and then invokes the application service programSVC1
.The program can interrogate theEIBTRNID
field to find this value.
