Starting with TTU 15.10.01, Teradata Tools and Utilities products no longer depend on LD_LIBRARY_PATH or the symbolic links created in /usr/lib and /usr/lib64 to find and load any dependent Teradata Tools and Utilities library. The Teradata Tools and Utilities products now use relative paths to find and load Teradata Tools and Utilities-dependent libraries. Moving any of the installed files to a different location will likely result in failures.
The symbolic links created in /usr/lib and /usr/lib64 are to allow third-party applications, such as Informatica, to find our shared libraries.
