ORA-28500

Dear all,
i have oracle 11gR1 installed on RedHat Eterprise linux X86_64 platform. I try to make a heterogeneous connectivity to SQL Server using Oracle Gateway 11g.
I already configure initdg4msql.ora, listener.ora and tnsnames.ora as in manual.
when I try to test the database link i've got some error messages
select * from dual@msqllink;
Error at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message: [Oracle][ODBC SQL Server Driver][libssclient22]General network error.
Check your network documentation.
[Oracle][ODBC SQL Server Driver][libssclient22]ConnectionOpen (connect()).[Oracle][ODBC SQL Server Driver]Invalid connection string attribute ORA-02063: preceding 2 lines from MSQLLINK
can anyone tell me the solutions for this problem?

commonly an error related to the initdg4msql.ora parameters like specifying a wrong server or using the wrong syntax.
Best would be to file a service request or post the config and we can have a look.

RE:ora-28500 when trying to insert into SQL Server table

Hi all!
I'm getting this when i attempt to insert into my table test in a SQL Server database. As u can see from the select, the database link seems ok. Any ideas plz. Thnx..
SQL> select "idAges" from test@try2;
no rows selected
SQL> insert into test@try2 ("idAges","nARAges","nAPAges") values(10,'','');
insert into test@try2 ("idAges","nARAges","nAPAges") values(10,'','')
ERROR at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Generic Connectivity Using ODBC][Microsoft][ODBC SQL Server Driver][SQL

IDENTITY_INSERT is set to OFF. (SQL State: 23000; SQL Code: 544)
ORA-02063: preceding 2 lines from TRY2

IDENTITY_INSERT on works only for particular session and for one table. It's not global variable.
The only idea what I have is to create link from MS Sql to Oracle (right now You have oracle ->ms sql)and then before insert You will set identity_insert on and will run insert.

Scenario:
I am having difficulty getting ODBC connection between Oracle OWB app with an 11gR2 DB (running on a VirtualBox Linux) and SQL Server 2008 running directly on the host. (Windows 8)
I am trying to take a SQL Server 2008 feed into Oracle Ware house Builder, and think(!) I have read everything and configured it in accordance (but I presume not given 3 days of failed attempts to fix it). I have also read several blogs, hence there might be a few more settings in the configuration files than the formal documentation says, but these have come from blogs that have “Solved” problems for other similar situations.
The environments:
HOST:
Name: RESOLVEIT-PC
IP: 192.168.1.80
Windows 8 (64bit) , with system DSN ODBC connection ACME_POS created with 32 bit ODBC set up (This setting still shows up fine in the 64 bit ODBC).

Let us rewrite your ODBC DSN a little bit... Your current odbc.ini looks like:
[ACME_POS]
Driver     = FreeTDS
Description = ODBC Connection via FreeTDS
Trace       = 1
Servername = 192.168.1.80
Database    = dbo
Let us change it a little bit so that we only need one config file - no odbcinst.ini nor freetds.conf file anymore:
[ACME_POS]
Driver =/usr/local/lib/libtdsodbc.so
Server = 192.168.1.80
Database
= dbo     #### I have some doubts that you have a SQL Server database called dbo - one database that always exists is master - so as a test use master here or get the real database name of the SQL Server database you want to connect
Port = 60801 ## make sure it really is the correct port - best would be to check on the SQL server and then try telnet <ip> <port> if you can connect to the SQL server
TDS_Version = 8.0
QuotedId=YES
Especially the last 2 parameters are mandatory. TDS_Version specifies the TDS Version you have to use to connect to the SQL Server and QuotedID is required for DG4ODBC as it surrounds objevt names by double quotes.
What happens now when you try to connect with for example isql - the ODBC test utility shipped with the ODBC Driver manager?
In addition, could you please do me another favour and check the word size of DG4ODBC and the ODBC Driver Manager as well as the ODBC Driver - just execute:
file /u01/app/oracle/product/11.2.0/dbhome_1/bin/dg4odbc
file /usr/local/lib/libtdsodbc.so
file < the patch to your libodbc.so library>/libodbc.so
and post the output.

There is a typo in the name of you gateway init file. You posted the content of inithMYSQL.ora but the naming is init<SID>.ora which is in your case initMYSQL.ora.
In addition please keep in mind HSODBC has been desupported since 2008 and when starting a new configuration you should use the follow up product dg4odbc (Database Gateway for ODBC) V11.

Just to clarify - did you abort the fetch?
What about your network environment - are all machines located in the same network or is for example the SQL Server located outside of your network?
Is there an rdbms/log directory in your OH /u01/app/oracle/product/11.2.0/db_1?
If yes, does it contain a dump file dated with 2011/10/12-08:04:54?
If there is no rdbms/log directory, please create it and retry the select.
BTW, there's already dg4msql 11.2.0.2 and for some platforms also 11.2.0.3 available. Could you also please make sure you use the latest release?

ORA-28500: connection from ORACLE to a non-Oracle system returned

Hi All,
My database is in 10.2.0.4 and has a dblink to sqlserver. The dblink works fine for normal queries.
However when executing the following query from my oracle database
SELECT ROWNUM, "ad2_id", my_name, "data"
FROM "abc"@xyz.com
WHERE "startDateTime" > (TO_DATE ('20100120', 'YYYYMMDD') - 1)
AND "startDateTime" < TO_DATE ('20100120', 'YYYYMMDD')
AND ROWNUM < 101
I am getting the following error
Note : Line 8 is "startDateTime" > (TO_DATE ('20100120', 'YYYYMMDD') - 1)
ERROR at line 8:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
ORA-02063: preceding line from xyz
Note:
1.data is of datatype VARCHARN(1000) and if we ignore that field I am able to get the output
2. If I give the StartDateTime to a value without using to_date I am able to get the output.
Could you please tell me what could be the problem ?
Thanks in advance.

The problem as far as I am know is if I try to select data and use both the where clauses I am getting the error.
Which is
SELECT ROWNUM, "ad2_id", my_name, "data"
FROM "abc"@xyz.com
WHERE "startDateTime" > (TO_DATE ('20100120', 'YYYYMMDD') - 1)

Please notify the site's webmaster and try your request again later. when I look up ORA-28500 and ORA-02063 in the on-line documentation right now :(
Is your database connect string correct? The ones I use don't have .com attached to them.

ORA-28500 and ORA-02063 while connecting MySQL from Oracle-

Dear All,
My Database is Oracle 11gR2 Rac of 2 nodes and on Linux 64-Bit operating system.
Version of my MySQL database is 5.5.17 it is on Linux 32-Bit operating system.
I am trying to connect MySQL database from Oracle database using a database link.
These are the step by step process that I am following to achieve my target. All my processes are on one node of Oracle RAC.
1)
Yum install mysql-connector-odbc
Yum install unixODBC
2)
Edit file /etc/odbc.ini
[test]
Driver = /usr/lib64/libmyodbc3.so
Description = MySQL ODBC 3.51 Driver DSN
SERVER = 10.0.0.1
PORT = 3306
USER = test
Password = test
Database = test
OPTION = 3
SOCKET =
3)
Edit file /etc/odbcinst.ini
[MySQL]
Description = ODBC for MySQL
Driver = /usr/lib64/libmyodbc3.so

FileUsage = 1
4) test connection
isql –v test test test
Returns:
| Connected! |
| |
| sql-statement |
| help [tablename] |
| quit |
| |
SQL>
5) Now I edit listener.ora file and add the entry. After entry my listener.ora file is like this:
LISTENER =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = LISTENER))
(ADDRESS = (PROTOCOL = TCP)(HOST=testnode1)(PORT = 1521))
# line added by Agent
LISTENER_SCAN1 =
(DESCRIPTION =

# line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN1 = ON # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER = ON # line added by Agent
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
(PROGRAM = extproc)
(SID_DESC =
(PROGRAM = dg4odbc)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = test)
(ENVS=LD_LIBRARY_PATH = /usr/local/lib:/u01/app/oracle/product/11.2.0/dbhome_1/lib)
6) After these entries the listener status after RESTART is as following:
LSNRCTL> status
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521)))
STATUS of the LISTENER
Alias LISTENER
Version TNSLSNR for Linux: Version 11.2.0.1.0 - Production

Service "racdbXDB" has 1 instance(s).
Instance "testdb1", status READY, has 1 handler(s) for this service...
The command completed successfully
7) Then in the tnsnames.ora file I added the following entry:
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS =
(PROTOCOL = IPC)
(KEY = EXTPROC1521)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
test =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.0.0.1)(PORT = 1521))
(CONNECT_DATA =
(SID = test)
(HS = OK)
When i tnsping test, it works.
8) I edit the .bash_profile file for Oracle
ORACLE_HOME, ORACLE_BASE were already pointing to the correct destination, I added:
LD_LIBRARY_PATH=/usr/local/lib:/u01/app/oracle/product/11.1.0/db_1/lib:/u01/app/oracle/product/11.2.0/dbhome_1/hs/lib:/usr/lib64:/usr/lib
export LD_LIBRARY_PATH
ODBCINI=/etc/odbc.ini
export ODBCINI
ODBCINSTINI=/etc/odbc.ini
export ODBCINSTINI
ODBCSYSINI=/etc
export ODBCSYSINI
9) Then i configured $ORACLE_HOME/hs/admin/inithsodbc.ora
And Modified these lines:
HS_FDS_CONNECT_INFO = test
HS_FDS_TRACE_LEVEL = ON
HS_FDS_TRACE_FILE_NAME = odbc_test.log
HS_FDS_TRACE_LEVEL = 4
HS_FDS_SHAREABLE_NAME = /usr/lib64/libodbc.so
HS_FDS_SUPPORT_STATISCTICS = FALSE
HS_LANGUAGE = AMERICAN_AMERICA.WE8ISO8859P1
set ODBCINI = /etc/odbc.ini
10) Then i created a database link with the following command:
Create public database link test connect to test identified by test using ‘test’;
I tried username and password in database link with double quotes also.
11) Now Finally when I try to select records from mysql table:
select count(*) from "table"@"test"; -- I have tried with and without double quotes
I get the following error:
ERROR at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
ORA-02063: preceding line from TEST
How to get through this error, and how to check logs for HS?
Your help is required.
Regards, Imran

Hi,
In your listener.ora for the DG4ODBC entry you had -
(ENVS=LD_LIBRARY_PATH = /usr/local/lib:/u01/app/oracle/product/11.2.0/dbhome_1/lib)
but this should also include the path for the driver manager directory which in your case is /usr/lib64 so could you add this ?
The error -
Failed to load ODBC library symbol: /usr/lib64/libmyodbc3.so(SQLSetDescRec)
indicates the /usr/lib64 directory cannot be accessed.
The entry should then look like -
(SID_DESC =
<space>(PROGRAM = dg4odbc)
<space>(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
<space>(SID_NAME = test)
<space>(ENVS=LD_LIBRARY_PATH = /usr/local/lib:/usr/lib64:/u01/app/oracle/product/11.2.0/dbhome_1/lib)
<space>)
The spaces may have bene lost when posting but there should be at least one space in the file as indicated by the <space>.
After making the change then stop and start the listener.
If you still have problems then please post again the current versions of the configuration files, the full errors shown in SQLPLUS for a select and the output from a debug trace showing the errors.
The information shows you are using the 3.51 MySQL ODBC driver so could you also try with the latest version of the 5.1 driver and see if you have the same problem ?
Regards,
Mike

Issue ORA-28500 dblink from Excel

Masters
I need help
I created an oracle in DBLINK to access an Excel spreadsheet, but when I run the select returns the following error:

ORA-28500 error message

Dear all,
i have oracle 11gR1 installed on RedHat Eterprise linux X86_64 platform. I try to make a heterogeneous connectivity to SQL Server using Oracle Gateway 11g.
I already configure initdg4msql.ora, listener.ora and tnsnames.ora as in manual.
when I try to test the database link i've got some error messages
select * from dual@msqllink;
Error at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message: [Oracle][ODBC SQL Server Driver][libssclient22]General network error.

can anyone tell me the solutions for this problem?
thanks b4

actually this is a simple mistake that i found when i'm doing re-check on tnsnames.ora configuration.
i forgot to change the host name in tnsnames.ora (its still pointing to localhost, not the sqlserver machine IP)

How to resolve ora-28500 & ora-02063?

HI guys, recently, I have to read the data in MS SQL2008 into the oracle11gr2. At the first glance, I thought about the GateWay.
there are two servers in my team(run on vmware), which are:
server A: 192.168.184.130, winserver2003, 64 edition, MS server2008 installed, SP2 installed
server B: 192.168.184.134, winserver2003, 64 edition, oracle11gr2 and gateway installed, SP1.
on server A, the table of msdb.dbo.user_sqlserver2008 is the one the Oracle plans to read.
on server B, the ORACLE_HOME is C:\app\Administrator\product\11.2.0\dbhome_1, and the GATEWAY_HOME is C:\product\11.2.0\tg_1, both are default directories.
after the gateway component was installed, I configured the following files:
1. created C:\product\11.2.0\tg_1\dg4msql\admin\initmsdb.ora, the contents in this file are:
# This is a customized agent init file that contains the HS parameters
# that are needed for the Database Gateway for Microsoft SQL Server
# HS init parameters
HS_FDS_CONNECT_INFO=192.168.184.130//msdb
HS_FDS_TRACE_LEVEL=OFF

    (HS = OK)
after that, restarted the listeners for gateway and for orcl instance and the orcl instance as well, then on server B, logon as the user msdb possessing the resource and dba role,(what's more, there is another user id msdb on sqlserver2008, who is the owner of msdb database)
ran the following sql script via plsql:
1. create database link msdb connect to msdbadmin identified by "oracle_4u" using 'msdb';
2. select * from dbo.user_sqlserver2008@msdb
the script No.1 was successfully completed, while an error message was got in script 2. the message is:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Oracle][[ODBC SQL Server Driver][DBNETLIB]SQL Server dose not exist or access denied. {08001, NativeErr = 17}[Oracle][ODBC SQL Server Driver][DBNETLIB]ConnectionOpen(Connect()). {01000, NativeErr = 2}[Oracle][ODBC SQL Server Driver]Invalid connection string attribute{01S000}
ORA-02063: preceding 2 lines from MSDB.
Could anyone familiar with this help me figure this out? Thanks, it made me crazy.

On the gateway side you don't need to specify the port number when your SQL Server is listening on the default port. But in your update you also mentioned that you had to configure also the SQL Server to use port 1433 - this indicates that it wasn't configured earlier ... so the SQL Server was using dynamic ports and when you use dynamic ports and the gateway you have to make sure on the SQL Server side the SQL Browser service is running AND you specify the instance name in your HS_FDS_CONNECT_INFO like HS_FDS_CONNECT_INFO=192.168.184.130/<instance name of the SQL Server>/msdb
