Architectural Changes

RTR Version 3 introduces certain process and other architectural changes. The following sections highlight these changes.

3.1 RTR Daemon Process

In RTR Version 3, a new RTR daemon process (called RTRD) is used by the RTRACP process to build TCP/IP connections for internode links. The RTR daemon process is present only on systems with IP networking installed and with IP enabled as an RTR transport (see Chapter 4, Network Issues, for information on setting your network transport).

3.2 Command Server Process

The command server process name is RTRCSV_<username>.

In RTR Version 2, a command server was started for every user login invocation to RTR to enter operator commands. With RTR Version 3 there is one command server per node for each user logged in through a common user name.

Note

Command server timeouts are the same in RTR V3 as in RTR V2.

3.3 The Shared Library (LIBRTR.EXE)

In RTR Version 3, LIBRTR supersedes RTRSHR. This library module LIBRTR contains most of the RTR code, in contrast with RTR Version 2, where only RTR code specific to application context was contained in RTRSHR. All RTR Version 2 binaries have been superseded by the two executables LIBRTR.EXE and RTR.EXE, in RTR Version 3. Table 3–1 shows the executables of RTR Version 2 and Version 3.
