PK81905: WSIM TCP/IP FULL SERVER SUPPORT

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• TCP/IP FULL SERVER SUPPORT FOR SIMPLE TCP/IP ( STCP )
  SIMULATIONS PROVIDES A MEANS FOR SIMULATING SERVERS SUPPORTING
  MULTIPLE CLIENT SOCKET CONNECTIONS IN PARALLEL. THE TPNS TCP/IP
  FULL SERVER SUPPORT IS ENABLED WHEN A DEV WITH TYPE=STCP AND
  STCPROLE=SERVER ARE CODED AND NEW OPERANDS BACKLOG=N OR
  MAXCLNTS=N IS ALSO CODED WITH AN 'N' VALUE GREATER THAN ONE.
  SAMPLE DATA SET MEMBER TCPFSDOC DOCUMENTS THIS NEW SUPPORT.
  ALSO, INFORMATION MESSAGE ITP433I CAN NOW BE INHIBITED.

  TCP/IP Full Server Support for Simple TCP/IP ( STCP )
  simulations provides a means for simulating servers supporting
  multiple client socket connections in parallel.  The TPNS TCP/IP
  Full Server support is enabled when a DEV with TYPE=STCP and
  STCPROLE=SERVER are coded and new operands BACKLOG=n or
  MAXCLNTS=n is also coded with an 'n' value greater than one.
  Sample data set member TCPFSDOC documents this new support.
  Also, information message ITP433I can now be inhibited.

Problem conclusion

Temporary fix

Comments

• BACKLOG=1-32767 (1 default) and MAXCLNTS=1-1999 (1 default)
  operands added.  If BACKLOG=n or MAXCLNTS=n value greater than
  one, enable TCP/IP Full Server support for
  DEV TYPE=STCP,STCPROLE=SERVER.  LISTEN() on LOCLPORT=n port
  number and ACCEPT() socket connections up to MAXCLNTS=n value
  in parallel.  Allow ITP433I to be inhibited.
