Hi,
I am trying to call an external procedure (C language dll) from PL/SQL but I get the following error:
ORA-28575: unable to open RPC connection to external procedure agent
I have read a lot about thie resloution of this problem by configuring tnsnames and listner properly. But the error remains the same. Following are my configuration info:
********* tnsnames.ora entry ***********
extproc_connection_data=
(DESCRIPTION =

(PROTOCOL = IPC)
(KEY = DLLTEST)
)
(CONNECT_DATA = (SID = extproc)

tnsping also returns successful result.
I have tried the demo application in the

Everything seems to be on track as experts have mentioned on web. but I think I still miss something.
Looking for ur help.
