After upgrading from 8i to 220.127.116.11, calling an external procedure errors with:
ORA-06520: PL/SQL: Error loading external library
ORA-06522: ld.so.1: extproc: fatal: /app/oracle/ext/scripts/report_prod_sh.so: wrong ELF class: ELFCLASS32
Oracle software upgrade from a pre-11.2.0.X release to 11.2.
In 11.2, when installing "regular" Oracle on a 64-bit o/s, you only get 64-bit executables and libraries.
In prior releases, we installed 32-bit and 64-bit executables and libraries simultaneously.
The libraries resided in separated directories - $ORACLE_HOME/lib and $ORACLE_HOME/lib32
(9i and above) or $ORACLE_HOME/lib and $ORACLE_HOME/lib64 (8i).
