External Procedure Agent

Hello!
Is It Possible To Call 32Bit Libraries Using External Procedure Agent Extproc On Windows 64Bit ?
Thanks a lot

Hi,
I am not sure of that, but I think you get Exceptions. If any document refernce you want the please find the link Oracle9i Application Developer's Guide - Fundamentals Release 2 (9.2)

Hello,
I had installed ore 1.3.1 windows server 2008 on top of Oracle DB 11.2.0.3 ,but when I connect the database,it didn't work.
That is my code and error code.
ore.connect(user = "rquser", sid = "db11g", host = "....", password = "....", all = TRUE)
Got error as below:
error.oci.GetQuery(conn, statement, data = data, prefetch = prefetch, :

Hi Sandy,
If you set EXTPROCS_DLLS=ANY in the listener and then restart the listener, does it fix the problem?

Please tell me to resolve this problem

Does not execl() and friends replace the current program with the one supplied as a parameter?
The upshot of this would be as you suggest, viz:
- Oracle call's your procedure (but doens't wait for a result due to the void return type?)
- your program executes its code (cd /tmp)
- it then replaces itself with *program
- *program terminates
Presumably, Oracle isn't expecting it to terminate but to continue waiting for subsequent requests.
I'd check out fork() and see if that offers more appropriate semantics.

ORA-28575: unable to open RPC connection to external procedure agent

Hi everybody,
Could you please help me with this problem? I'm trying to configure Oracle XE 11g for external procedures, this because I have to access some procedures in a DLL made in Delphi 6.0, but even with the simplest of the dll I make, like a sum made in C, I can't get pass this error ORA-28575: unable to open RPC connection to external procedure agent.
This is my listener.ora:
SID_LIST_LISTENER =

(ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)

and this is my tnsnames.ora:

Do you know what could be wrong? I'm out of ideas and google search...
Also, is there any difference in a calling for a DLL made on VB and one made in Delphi??
Thanks and Regards,

Hello,
This error could appear due to issues with configuration of your listener, database or with extproc. First check that the permissions on extproc in your Oracle_home specified in your listener.ora file are valid:
Run the following ./extproc and it should display the banner.
If above is ok, then check for the domain name. One probable reason could be that if default_domain is set and that domain is not appended to the service name in tnsnames.ora, the connection fails.

ORA-28576 lost RPC connection to external procedure agent

Hello!
NT 4.0, O9i 9.0 and 9.2
Calling external DLL procedure produces the following error:
"ORA-28576 lost RPC connection to external procedure agent"
The external DLL is in the ORACLE_HOME/bin directory.
The same application works fine on 8.1.7 !
I didn't find any useful info in 9i docs (App. dev. fundamentals; Net guide...).
Is there any significant difference in EXTPROC feature between 8.1.7 and 9.x ?
Thanks for any useful info

I have the same problem using Windows kernel32.dll. It works fine with Oracle8 and Oracle8i on both Windows NT and Windows2000, but it does not work with Oracle9i on Windows2000. After long discussions, Oracle has admitted that it is a bug. If you have access to metalink then see TAR 2189019.995.

Getting "ORA-28576: lost RPC connection to external procedure agent" for R scripts.

Hello,
I am trying R integration with OBIEE. As part of this, I have created a simple R script for a scatter plot. Below is the R script
begin
sys.rqScriptCreate('randomRedDots',
                     'function()
                        res <- 1:10
                        plot(1:100, rnorm(100), pch=21, bg="red", cex=2)
                        res
end;
I am testing this script in SQL Developer by executing the below sql:
select image
from table(rqEval(NULL,
                  'PNG',
                  'randomRedDots')
During these tests, very often, I get ORA-28576 error when I run the SQL. The complete error is:
ORA-28576: lost RPC connection to external procedure agent
ORA-06512: at "RQSYS.RQEVALIMPL", line 77
ORA-06512: at "RQSYS.RQEVALIMPL", line 74
28576. 00000 - "lost RPC connection to external procedure agent"
*Cause:    A fatal error occurred in either an RPC network connection,
           the extproc agent, or the invoked 3GL after communication had
           been established successfully.
*Action:   First check the 3GL code you are invoking; the most likely
           cause of this error is abnormal termination of the
           invoked "C" routine. If this is not the case, check for
           network problems. Correct the problem if you find it. If all
           components appear to be normal but the problem persists, the
           problem could be an internal logic error in the RPC transfer
           code. Contact your customer support representative.
However, if I re-run the SQL, I do not get this message. This happens at random.
Any pointers to why this error occurs?
Thanks,
Abhishek

Abhishek,
Please look for a core file in $ORACLE_HOME/hs/log and look for errors in the call stack associated with the core file.
Examining the errors will help identify the cause of the intermittent ORA-29576 error.
Thank you,
Sherry

Error Calling an external procedure

I'm calling an external procedure (provided by a third party).
When i invoke it from a client code, it functions.
When I invoke it from PL/SQL code, it gives the following error:

The solution in the help file states it could be a timeout problem.
If so, what is the solution to the problem. (I cannot access the source of the DLL subroutine).

Error calling external procedure on remote server

Hello
I have written an external procedure that runs correctly when it is on the same machine as the database from which I call it. (Windows XP Professional/Oracle 9.2)
When I try to call the procedure from a database on another machine (also Windows XP Professiona l/ Oracle 9.2) I get ORA - 28756 "lost RPC connection to external procedure agent" or ORA - 28758 "protocol error during callback from an external procedure". Using filemon I can see that the DLL is never searched for or called. The problem seems to lie in the communication between the two machines. When I observe network traffic the machines communicate on port 1521 (the listener) and then switch to the port that the listener returns. Shortly after that the connection is terminated with the above error reported in the PL/SQL routine.
The Oracle Administrator's Guide (9.2) states that "the agent must reside on the same computer as the application making the external procedure call." However there are several entries on the internet that show how to do what I am want to accomplish - I suspect I am making some small mistake.
Any help would be greatly appreciated!
Here is the listener on the machine with the DLL.
LISTENER =

no problem!!
Where is the problem ? is OS problem ?
How to start RPC daemon in Linux ??.....
I use Redhat 5.2 .......
Thanks !

Dear Mark :
I have followed your method, but not work for Linux ....
I have succeeded for starting the external-procedure call by
"oracle for Solaris" , no problem ....
I think that "Linux RPC Daemon" is NOT running ...
how to Start it ?

External Procedure Error: Ora-28575

We are trying to set up external procedures in an HP/UX environment. However, we can not seem to get past the following error:
ORA-28575: unable to open RPC connection to external procedure agent
The following is our TNSNAMES.ORA set up:
EXTPROC =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = extproc_key))
(CONNECT_DATA =
(SID = extproc_agent)
The following is the listener.ora setup:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = ssi2)(PORT = 1521))
(PROTOCOL_STACK =
(PRESENTATION = TTC)
(SESSION = NS)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = extproc_key))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = SDST.world)
(ORACLE_HOME = /u001/app/oracle/product/SDST)
(SID_NAME = SDST)
(SID_DESC =
(SID_NAME = extproc_agent)
(ORACLE_HOME = /u001/app/oracle/product/SDST)
(PROGRAM = extproc)
The following is the SQLNET.ORA setup:
SQLNET.EXPIRE_TIME = 0
NAMES.DIRECTORY_PATH= (TNSNAMES)
Does anyone have any ideas/help??? We're stuck. Thanks!

Hi,
I guess, it is happening in connection point only. Other wise It will give another error "RPC lost connection".
I will give some tips.
1.".so" path should match with oracle library path. For this one, u can query ur system tables and verify.
2. When u create external procedure, be careful. Especially, when u give name of procedure and library. Pls. check this particular part.
Pls. let me know the progress. U can directly contact me through the mails.

Problem with Oracle external procedures and Microsoft Active Directory

Hi,
Our server was recently updated to use Microsoft Active Directory. However, we noticed that all external procedure calls keeps on failing with ORA-28575: unable to open RPC connection external procedure agent. Everything was working fine before we migrated to Active Directory which is why we can say that the listener is configured correctly.
Any idea on how we can make extproc calls with Active Directory?
thanks.

Michael,
Oracle Forms does support Single Sign-On (SSO). Take a look at Oracle Containers for J2EE Security Guide: OC4J Java Single Sing-On. Also take a look at the Oracle Forms 10g Sample Code and scroll to the SSO demo under the Forms Services Demo section. There are also, numerous other documents available via Google. ;-)

Remote external procedure call ORA-28576

Hi,
I have to call an external procedure (c program) which is in another(remote) host system.
I have created a simple c program and when i call it from the same database host (Oracle 11.2.0.3 in linux 2.6.39) every thing work fine, but when i call it from another database found in a remote host (Oracle 11.2.0.3 HP-UX 11iv3) i receive these error "ORA-28576". The "extproc" program was started by the listener (i can see that in the listener logfile) but then the connection was aborted.
So my question is can i call remote external proc program from a remote host ? if yes how can i do that ? thanks for help
Configuration :
listener.ora
LISTENER =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = MYHOST)(PORT = 1521))
SID_LIST_LISTENER =
    (SID_LIST=
        (SID_DESC= (SID_NAME=callout)
        (ORACLE_HOME=/app/oracle/11.2.0.3)
        (ENVS = 'EXTPROC_DLLS=/tmp/test.so')
        (PROGRAM=extproc)
tnsnames.ora
extproc_connection_data =
   (DESCRIPTION =
       (ADDRESS = (PROTOCOL=tcp)(host=MYHOST)(port=1521))
       (CONNECT_DATA=(SID=callout))
test.c
#include <stdio.h>
int square(int x)
return((x*x) + 1); //adds 1 to the return value
PL/SQL code
CREATE DATABASE LINK agent_link USING 'extproc_connection_data';
CREATE OR REPLACE LIBRARY test_lib IS '/tmp/test.so' AGENT 'agent_link';
CREATE OR REPLACE FUNCTION test_proc (X BINARY_INTEGER) RETURN BINARY_INTEGER
AS
EXTERNAL LIBRARY test_lib
NAME "square"
LANGUAGE C;
CREATE OR REPLACE PROCEDURE EXTPROCTEST (X BINARY_INTEGER)
AS
   RetValue   BINARY_INTEGER;
BEGIN
   RetValue := test_proc (X);
   DBMS_OUTPUT.PUT_LINE (RetValue);
END;
SET SERVEROUTPUT ON
EXECUTE EXTPROCTEST(10);

Hi,
I found the answare, it seem that for security reason the listener,extproc agent and the instance must be on the same host.
Reference : (http://docs.oracle.com/cd/E11882_01/appdev.112/e10825/pc_07pls.htm#sthref1051)
>
The database server, the agent process, and the listener process that spawns the agent process must all reside on the same host.
>
>
For security reasons, extproc, by default, loads only DLLs that are in directory $ORACLE_HOME/bin or $ORACLE_HOME/lib. Also, only local sessions—that is, Oracle Database client processes that run on the same system—are allowed to connect to extproc.
