I am currently 10g to 11g database migration and trying to configure EXTPROC. EXTPROC32 was configured as part of 10g to execute C++ library and working fine.

It appears that 11g does not provided EXTPROC32 so C++ library compiled for 64 bit and configured as follows.

Listener configuration and confirmed file is available in /opt/UTILfddb/lib/utillib.so. in database server.

  (ADDRESS = (PROTOCOL = IPC)(KEY = extproc))
  (PROGRAM = extproc)
  (ENVS = "EXTPROC_DLLS=/opt/UTILfddb/lib/utillib.so,LD_LIBRARY_PATH=/usr/ucblib/sparcv9:$LD_LIBRARY_PATH")
  (SID_NAME = extproc)
  (ORACLE_HOME = /u01/app/oracle/product/

Following errors returned when try to execute pl/sql function:

SQL> select gmt_sysdate from dual;
select gmt_sysdate from dual
ERROR at line 1:
ORA-06520: PL/SQL: Error loading external library
ORA-06522: ld.so.1: extproc: fatal: /opt/UTILfddb/lib/utillib.so: open failed:
No such file or directory
ORA-06512: at "UTIL.GMT_SYSDATE", line 4

Do I need to grant any permission to oracle user to execute or load this file? Can you please help to resolve this issue? Let me know if you need any further information. Thanks

    You're on Solaris, yeah? Have you definitely compiled it for the correct architecture? Run file /opt/UTILfddb/lib/utillib.so and file $ORACLE_HOME/bin/oracle and make sure the architectures are the same. Also, Solaris uses SHLIB_PATH, not LD_LIBRARY_PATH. Another thing to check is ldd /opt/UTILfddb/lib/utillib.so to check that all of the libraries dependencies are available – Philᵀᴹ Jun 7 '16 at 6:18
  • Thanks, Details updated and according to docs.oracle.com/cd/B19306_01/network.102/b14213/listener.htm LD_LIBRARY_PATH path configured – nayakam Jun 7 '16 at 7:33
