You need to setup the listener.ora and tnsnames.ora file for extprocs.

Here is a sample listener.ora file:

LISTENER =
  (ADDRESS_LIST =
    (ADDRESS=(PROTOCOL=IPC)(KEY=oracle81.world))     (ADDRESS=(PROTOCOL=TCP)(Host=sheepdog)(Port=1521))   )
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =

      (GLOBAL_DBNAME=sheepdog.us.oracle.com)
      (ORACLE_HOME= /d01/home/oracle81)
      (SID_NAME = oracle81)

)
(SID_DESC =

      (SID_NAME = extproc)
      (ORACLE_HOME = /d01/home/oracle81)
      (PROGRAM = extproc)
      #(ENVS=DEBUG_MODULES=all,DEBUG_FILE=/tmp/test/ext_proc.log)

)
)
STARTUP_WAIT_TIME_LISTENER = 0
CONNECT_TIMEOUT_LISTENER = 10

The important things in the listener file for extprocs:

o ADDRESS=(PROTOCOL=IPC)(KEY=oracle81.world))

set up an IPC based listener. remember the value of the KEY= (you can make it whatever you want, just remember what it is)

o (SID_DESC=(SID_NAME=extproc)

remember that SID_NAME, call it extproc.

o (ENVS=DEBUG_MODULES=all,DEBUG_FILE=/tmp/test/ext_proc.log)

if you want a specific set of environment variables setup for your extproc routines, put them here, separated by commas. The above for example, sets up 2 environment variables for the extproc servcies, DEBUG_MODULES and DEBUG_FILE. Since extprocs run detached from a console and are a little touchy to debug, having copious amounts of 'tracing' that you can enable/disable via the environment is suggested (by me)...

The next file is the tnsnames.ora file, it needs an entry like:

extproc_connection_data =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = IPC)(KEY = oracle81.world))     (CONNECT_DATA = (SID = extproc))
  )

Important things:

o (ADDRESS = (PROTOCOL = IPC)(KEY = oracle81.world))

should be the same as was in the listener.ora file....

o (CONNECT_DATA = (SID = extproc))

the sid must match the sid in the (SID_DESC=(SID_NAME=extproc) from the listener.ora....

Also, if your sqlnet.ora specifies some default domain, it needs to be on the tnsnames entry. So if you have a sqlnet.ora with stuff like:

sqlnet.authentication_services=(none)
names.directory_path = (TNSNAMES, HOSTNAME) names.default_domain = world
name.default_zone = world
automatic_ipc = off

in it, that would be extproc_connection_data.world -- not just extproc_connection_data.
