3 Migration Considerations
This section discusses the differences between the Parallel Library TCP/IP and
conventional TCP/IP which you should consider when migrating to Parallel Library
TCP/IP. Sample startup procedures for both subsystems are compared side-by-side to
show the SCF differences as well as some procedural differences (such as a new
system DEFINE). Finally, some tips are provided for consideration when migrating to
Parallel Library TCP/IP.
Parallel Library TCP/IP is transparent for Guardian and OSS socket applications; to
access Parallel Library TCP/IP, simply specify a TCPSAM process instead of the
conventional TCP/IP process. However, note that you must consider the effect of
specifying TCPSAM on your various applications. Those considerations are listed in
this section.
For complete SCF command syntax as well as subsystem configuration information
and methods of maximizing the benefits of Parallel Library TCP/IP architecture, see the
TCP/IP (Parallel Library) Configuration and Management Manual.
