You need to setup the listener.ora and tnsnames.ora file for extprocs.
Here is a sample listener.ora file:
(GLOBAL_DBNAME=sheepdog.us.oracle.com)
(ORACLE_HOME= /d01/home/oracle81)
(SID_NAME = oracle81)
(SID_NAME = extproc)
(ORACLE_HOME = /d01/home/oracle81)
(PROGRAM = extproc)
#(ENVS=DEBUG_MODULES=all,DEBUG_FILE=/tmp/test/ext_proc.log)
)
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:
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.
