APPLIES TO: Hyperion BI+ - Version 11.1.1.0.00 to 11.1.2.3.503 [Release 11.1] Linux x86-64 SYMPTOMS Unable to run SQR after installation on Linux, getting error: sqr: error while loading shared libraries: libclntsh.so.11.1: wrong ELF class: ELFCLASS64 CAUSE Missing Oracle 32-bit client libraries in SQR's environment. SQR is only finding the incompatible 64-bit Oracle libraries and throwing an error. Starting with Oracle 11 the 32-bit client libraries don't get installed automatically on 64-bit systems.  SOLUTION Make sure the Oracle 32-bit client libraries are installed and in SQR's environment. If installed they're usually in the ORACLE_HOME/lib32 directory.  The location of the Oracle 32-bit client libraries has to be added to the LD_LIBRARY_PATH.
