| Defect/Enhancement Number | |
| Cause | Normally due to the environment file not being sourced. |
| Resolution | 1. Before running your application make certain that you have sourced the environment file. This file is generally located at: <<Orbix install>>\\etc\\bin\\<<domain name>>_env. 2. Start shared library debugging with by setting the environment variable IT_SHLIB_VERBOSE: IT_SHLIB_VERBOSE=1 export IT_SHLIB_VERBOSE 3. Run your service or application. 4. In the standard output, search for an error message referencing a library which cannot be found or loaded. The library name will be of the form it_arm5. This is not the name of the actual shared library. The shared library name will be libitit_arm_<<compiler>>.so.<<version number>>. For example libit_arm_gcc34_so.5 . 5. Find your shared library path. 5. a. On AIX run the command : echo $LIBPATH 5.b. On LINUX run the command: echo $LD_LIBRARY_PATH 6. Does the referenced shared from step 4 exist in the shared library path from step 5? If not then add the path to the configuration file from step 1. 7. If the library does exist then check the user permissions on this file. Does the Orbix process have permissions to run this file. 8. If the process does have permissions for the file then check that all library dependencies for the file can also be loaded. 8.a. cd to the directory containing the shared library. 8.b. run the command: ldd <<shared library>> Check that each library needed for the shared library can be found and loaded. If there exist any missing shared libraries then change the path accordingly. 9. Make certain that if you have installed a 32 or 64 bit version of Orbix then you also use the appropriate 32 or 64 bit version of Java. (check the java version from the LIBPATH or LD_LIBRARY_PATH.) |
