Cannot create Transport caused by: TibrvException[error=27,message=Tibrv already open using different implementation]


Environment:
===========

   o For all BW versions
   o Mostly on 64-platforms

Cannot create Transport caused by: TibrvException[error=27,message=Tibrv already open using different implementation]

The above RV error can be resolved by one of the following steps.

1. Try deleting the rvd and restarting it.

2. make sure that you have the following environment variables correctly set in bwengine and designer tra files,

   CLASSPATH=&ltRV_HOME>/lib/tibrvj.jar:...
   PATH=&ltRV_HOME>/tibrv/bin:...
   SHLIB_PATH=&ltRV_HOME>/lib:... (on HPUX)
   LD_LIBRARY_PATH=&ltRV_HOME>/lib:...   (on Solaris and Linux)
   LIBPATH=&ltRV_HOME>/lib:...   (on AIX)

  Check for any mismatch between the version of RV Java library pointed to by the CLASSPATH and the version of the RV native libraries that
  the PATH, LD_LIBRARY_PATH (on Solaris) and SHLIBPATH (on HPUX) variables must reference.

  Make sure that above 4 PATH Variables are pointing to the same RV installation.
  Make sure that they don't point to multiple locations.

3. If the issue still occurs:
  Then check your tibco/designer/5.x/bin/designer.tra file to see if %RV_HOME%/bin is included in tibco.env.PATH.
  If not, add %RV_HOME%/bin%PSP%.

4. Move %RV_HOME%/lib to the beginning of the line of ClassPath and LIBRARY PATH.

5. If all of TIBCO products are using 64-bit version make sure RV is also using 64-bit version
