Hi,

We are asked to configure extproc in our environemnt .

while executing exptproc from ORACLE_HOME/bin,I am getting the following error.

$./extproc

exec(): 0509-036 Cannot load program extproc because of the following errors:
rtld: 0712-001 Symbol kgesecl0 was referenced
      from module extproc(), but a runtime definition
      of the symbol was not found.
rtld: 0712-001 Symbol kgeresl was referenced
      from module extproc(), but a runtime definition
      of the symbol was not found.
rtld: 0712-002 fatal error: exiting.

Can anyone help me on this ?

Is athere any way to reinstall extproc ?
