IAF library paths
In order for the IAF to successfully locate and load C/C++ transport layer and codec plug-ins, the location(s) of these must be added to the environment variable LD_LIBRARY_PATH on UNIX, or PATH on Windows.
A transport or codec plug-in library may depend on other dynamic libraries, whose locations should also be added to the LD_LIBRARY_PATH or PATH environment variable as appropriate for the platform. The documentation for a packaged adapter will state which paths should be used for the adapter's plug-ins. Note that on the Windows platform, the IAF may generate an error message indicating that it was unable to load a transport or codec plug-in library, when in fact it was a dependent library of the plug-in that failed to load. On UNIX platforms the IAF will correctly report exactly which library could not be loaded.
When using the IAF with a Java adapter the location of the Java Virtual Machine (JVM) library is determined in the same way. On UNIX systems the LD_LIBRARY_PATH environment variable will be searched for a library called libjvm.so, and on Windows the IAF will search for jvm.dll, in directories on JAVA_HOME environment variable, then in any other directories on the PATH environment variable. Using a JVM other than the one shipped with Apama is not supported and Technical Support will generally request that any Java-related problems with the IAF are reproduced with the supported JVM.
See Java configuration (optional) for information about how the location of Java plug-in classes are determined.
