PI25505: HTTP TESTS BEHAVE DIFFERENTLY TO GREEN HAT SOFTWARE GH TESTER

Rational Integration Tester Fix Pack 4 (8.6.0.4) for 8.6
Rational Performance Test Server Fix Pack 4 (8.6.0.4) for 8.6
Rational Test Virtualization Server Fix Pack 4 (8.6.0.4) for 8.6

APAR status

• Closed as program error.

Error description

• Some tests that passed with GH Tester now fail when running in
  Rational Integration Tester (RIT).
  The first iteration of a test after starting RIT might work but
  subsequent ones fail.
  
  In GH Tester, HTTP connections are created for each action.
  In RIT, HTTP connections are pooled and are re-used to improve
  performance.
  
  For systems that expect new connections the RIT connection
  pooling causes problems.

Problem conclusion

• A start-up option has been added to turn off HTTP connection
  pooling, which reverts behavior to that in Green Hat Tester 5.x.
  Use of this option does reduce performance and should only be
  used on the advice of IBM Support.  The start-up option can be
  specified in Library Manager for Rational Integration Tester and
  the Rational Integration Tester Agent (for Rational Test
  Virtualization Server or Rational Performance Test Server
  customers) and consists of the following string:
  
  -Dgreenhat.http.pooling.off=true
