Oracle Database Discussions

Hello All,

We're encountering issues while trying to query a table using a db link to DB2 database.

We are running oracle 11g R1 on windows and we have DB2 installed on the box. We've installed database gateway for DRDA also on the same box. The gateway is running on a different home location within the same machine. But we get the following error while trying to query across the db link. Would be great if you can take a look and suggest appropriate changes.

ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: preceding 2 lines from UDB

Here's how we configured the gateway:

Listener:
-----------
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(SID_NAME=DB2)
(ORACLE_HOME=E:\app\Oracle\product\11.1.0\db_1)
(PROGRAM=g4drsrv)
)
(SID_DESC=
(SID_NAME=PLSExtProc)
(ORACLE_HOME=E:\app\Oracle\product\11.1.0\db_1)
(PROGRAM=extproc)
)
)

Tns:
------
dg4drda.idc.oracle.com =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = xpone.idc.oracle.com)
(PORT = 1521))
)
(CONNECT_DATA =
(SID= DB2))
(HS=OK)
)

initDB2.ora

DRDA_RECOVERY_USERID=ORADRDA
DRDA_RECOVERY_PASSWORD=ORADRDA
DRDA_ISOLATION_LEVEL=CS
DRDA_DISABLE_CALL=TRUE
DRDA_CODEPAGE_MAP=codepage.map


heres how we created the db link:

CREATE DATABASE LINK udb CONNECT TO ORACLE IDENTIFIED BY "welcome1" USING 'dg4drda.idc.oracle.com';

and this was the sql executed

select * from employee@udb;

Really appreciate your assistance.
