1.4 Components

Host Components

The main programs that support these extensions on the host are:

IBM i Visual LANSA Linux Listener LCOLIST LCOLIST.EXE lcolist program Transaction Program Entry LCOTP LCOTP.EXE lcotp program CPIC Manager LCOMGR40 LCOMGR32.DLL liblcomgr.so shared library Sockets IPC LCOSCK40 LCOSCK32.DLL liblcosck.so shared library Communications Routing Support LCOCROUT N/A liblcocrout.so shared library Administration LANSA CONFIGURE LCOADM32.EXE N/A DES LCOEDES LCOEDES.DLL liblcoedes.so shared library TWOFISH LCOETWF LCOETWF.DLL liblcoetwf.so shared library

These programs are used by the LANSA programs which service remote session requests. Existing LANSA functions and I/O modules need no change to run over these connections.

The Listener program (LCOLIST) is the component that waits for connection requests from remote sessions at a nominated port number or pipe. When the Listener receives a connection request, it transfers the connection to a Session Job, whose entry point is the Transaction Program Entry (LCOTP). The communications layer is provided by the CPIC Manager, the IPC Modules and on an IBM i, the Communications Routing Support (LCOCROUT).

Workstation Components

The components on the client workstation consist of an Administration Utility, an APPC interface DLL (known as the CPIC Manager), a Windows Sockets (Winsock) interface DLL (known as an IPC Module). These modules are installed during the LANSA setup.

The file names for these modules on Windows are:

Administration Utility LCOADM32.EXE CPIC Manager LCOMGR32.DLL Sockets IPC Module LCOSCK32.DLL DES Encryption Algorithm Module LCOEDES.DLL TwoFish Encryption Algorithm Module LCOETWF.DLL
