DirectConnect for z/OS Option performs these functions:
Receives requests from client applications
Converts the requests to the appropriate communications protocol call
Sends the requests to the mainframe
Each TRS or access service includes a unique server name, which clients use to select a server for communication, and has its own set of configuration information.
As shown in Figure 8-1, DirectConnect for z/OS Option uses four files:
srv.log for logging TDS traffic between TRS and client workstations, and for recording errors
ngtds for tracing Sybase TDS traffic between TRS and mainframe SNA
servername.log for logging TDS traffic between the access service and client workstations, and for recording errors
tds.trc for tracing Sybase TDS traffic between the access service and mainframe SNA
For more information, see the Mainframe Connect DirectConnect for z/OS Option Users Guide for Transaction Router Services and the Mainframe Connect DirectConnect for z/OS Option Users Guide for DB2 Access Services.
