DG4ODBC 11.2 to MySQL lost RPC connection to heterogeneous remote agent

Hi,
I'm running into an issue when executing a procedure in Oracle 11.2 which inserts into a table in a MySQL database over a database link. MOS suggested it is an issue with my unixODBC driver. MOS pointed me to a resolution, but I'm not sure how to successfully complete Step 2.
1. Please ensure you have a recent IBM ODBC driver for ISeries (ex: iSeriesAccess-5.4.0-x.x.x86_64.rpm).
2. Then recompile the source of the UnixODBC driver manager:
- First get the source of unixODBC driver manager
- Set the environment variable export CFLAGS="-DBUILD_REAL_64_BIT_MODE"
- Now follow the guidelines on the vendor's homepage how to link unixODBCdriver manager.
iSeriesAccess ODBC driver does not need to be recompiled if you have recent version.
Can anyone provide me more detail on how to do this? I'm trying to do this on SLES 11.
Thanks,
Joe

To the steps they outlined:
1. Please ensure you have a recent IBM ODBC driver for ISeries (ex: iSeriesAccess-5.4.0-x.x.x86_64.rpm).
=> goto IBM web site and download the IBM iSeries ODBC driver (64bit) for Linux
2. Then recompile the source of the UnixODBC driver manager:
- First get the source of unixODBC driver manager
=> www.unixODBC.org
- Set the environment variable export CFLAGS="-DBUILD_REAL_64_BIT_MODE"
=> not needed anymore as the 2.3 release is compiling by default this way - but you can set it to be sure.
- Now follow the guidelines on the vendor's homepage how to link unixODBCdriver manager.
=> in general to link the unixODBC driver manager you need to call:
./configure
make
make install
All available optiony options are listed on the uniodbc web site:
http://www.unixodbc.org/download.html
iSeriesAccess ODBC driver does not need to be recompiled if you have recent version. => which is already discussed in #1.

ORA-28511: lost RPC connection to heterogeneous remote agent using SID=

I am currently using the HS DG4ODBC on 11.2.0.3 with Linux X86-32bit platform, and I’ve gotten the gateway to work for all DML operations via DBLinks against a TimesTen database.
However, I am getting the following error in red when trying to execute the DBMS_COMPARISON package: ORA-28511: lost RPC connection to heterogeneous remote agent using SID=ORA-28511: lost RPC connection to heterogeneous remote agent using SID=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=timesten-hol)(PORT=1521))(CONNECT_DATA=(SID=hsodbc1)))
An internet search about the error leads me to think that this is a config issue with the cause being that:
Cause: The listener is unable to spawn the HS agent or the agent cannot find the ODBC lib directory.
Action: The PROGRAM line in the listener.ora file is incorrect or not specified. Make sure LD_LIBRARY_PATH includes the $ODBC_HOME/lib directory. If not, set LD_LIBRARY_PATH and restart the listener.
But I’ve revisited the settings and they all look OK, and also the HS agent seems to work fine for all types of DML operations on TimesTen, so I am at a loss of why the above error is occurring with dbms_comparison.compare.
I am also using the datadirect ODBC driver manager.
Thanks,

You've already filed a bug for this issue ( DG4ODBC CORE DUMP WHEN USING DBMS_COMPARISON.COMPARE) so please close this thread.

Hi,
It looks like the gateway connection has been closed for some reason and then you have tried to use it again in the same session which gives the ORA-28511.
There is a default gateway timeout but that is 20 minutes, whereas you are seeing problem after about 4 minutes and the listener timeout is set to 0.
Do you have any timeout settings configured in sqlnet.ora ?

Mike

Hi,
To follow up could you please provide the following information -
- the gateway listener.ora
- gateway init<sid>.ora
- gateway tnsnames.ora file
- create database link statement
- a gateway debug trace from the failing select. Add the following to the gateway init<sid>.ora file -
HS_FDS_TRACE_LEVEL=debug
and issue a select from a new SQLPLUS session, then end the session.
Are the gateway and the RDBMS in the same or different ORACLE_HOME directories ? The gateway is at a lower version than the RDBMS so you should apply the 11.1.0.7 patchset to the ORACLE_HOME where the gateway is installed, to bring it to 11.1.0.7.

Mike

Here's the details on the error message:

// *Cause: A fatal error occurred in one of the following places:

// *Action: Check for network problems and remote host crashes. The problem is
//          probably in the agent software. If so, contact a customer support
//          representative of the agent vendor.In my experience, this is usually caused by the OTG agent process failing.
Simple explanation - your db link to the OTG gateway connects to an Oracle listener that starts up an agent process. This process connects to the foreign database and acts as the gateway between your end and the foreign database. When this agent process fails, your side realises that the remote process is no more as it is no longer responding. The above error is then raised - as all your side knows that something critical went wrong on the agent side.
This agent has its own +.ora+ configuration file. One of the parameters that can be set is HS_FDS_TRACE_LEVEL (just confirm it for your OTG version - been years since I last used OTG). When the agent give problems, enable this parameter and have a look at the trace file generated by the agent process. The reason for the agent process failing should be listed in the trace file.

ORA-28511:lost RPC connection to heterogeneous remote agent

Hi,
I've a problem with Oracle 9i & DB2 communication.
I use main procedure that calls sub procedures. All the sub procedures executes a query on remote table.
When main procedure calls sub procedures by jobs, process works fine
ex:
DBMS_JOB.SUBMIT(jobno,'BEGIN subproc1; END;',sysdate+1/1440);
DBMS_JOB.SUBMIT(jobno,'BEGIN subproc2; END;',sysdate+1/1440);
When main procedure calls sub procedures without jobs Oracle show this error message:
ORA-28511:lost RPC connection to heterogeneous remote agent using SID=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP).....
Please HELP ME!!!!
thanks

I agree with ARF.
I kinda feel it has something to do with Heterogeneous Connectivity, maybe a dropped connection between Oracle and another vendor database.
check in this forum:

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.

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,

HS: Lost RPC connection to remote Agent...

Hi
We are using HS on Oracle 9206 on aix 5.1 to remotely connect to Informix also on aix 5.1 but another box. We are using Data Direct Wire Protocol drivers. The links are working fine. We use an application created from HTML DB which makes heavy use of HS.
The problem is we are getting...
HS: Lost RPC connection to remote Agent...
HS: ... Agent SID = (DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=51.1.20.6)(PORT=1523)))(CONNECT_DATA=(SID=prd01))), NCR status = -2147385341
In our alert log as the connections time out. This is "normal" behaviour but I wonder if anyone has any suggestions on how to minimise these? Typically we have c20-30 remote HS links open.

I have read a metalink article about an undocumented HS timeout parameter. HS_FDS_CONNECT_PROPERTIES="timeout='120'"
Has anyone any suggestions on this subject please.
Thanks

ORA-28575: unable to open RPC connection to external procedure agent when trying to connect ORE.connect

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, :
ORA-28575: unable to open RPC connection to external procedure agent
ORA-06512: at "RQSYS.RQEVALIMPL", line 17
ORA-06512: at "RQSYS.RQEVALIMPL", line 14
ORA-06512: at line 4
Also i have follwed the below link:
///ORE1.3-ore-server-win-x86_64-1.3,error ORA-28575: unable to open RPC connec
But failed to resolve the problem.

Hi Sandy,
If you set EXTPROCS_DLLS=ANY in the listener and then restart the listener, does it fix the problem?
SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (SID_NAME = EXTPROC)
      (ORACLE_HOME = H:\ORA11G\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ANY")
LISTENER =
(DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.168.11.69)(PORT = 1521))
