Each TRS library contains a TRS that provides access to DB2 data and supports Mainframe Connect Client Option mainframe applications, defined to TRS as remote procedure calls (RPCs).
TRS routes requests from remote LAN-based clients to Mainframe Connect Server Option transactions. Optionally, it can also route requests to the Mainframe Connect DB2 UDB Option and return results to the client.
Security can also be configured on a transaction or user basis.
There are two TRS libraries:
TRSLU62 service library, which uses the LU 6.2 communications protocol to talk to Mainframe Connect Open Server application running in CICS.
TRSTCP service library, which uses the Transmission Control Protocol/Internet Protocol (TCP/IP) communications protocol to talk to Mainframe Connect Open Server application running in CICS.
For an explanation of the TRS components of DirectConnect for z/OS Option, see the Mainframe Connect DirectConnect for z/OS Option Transaction Router Service Users Guide.
