Oracle connectivity to SQL Sever

Does anyone know how to develop a DB link between a Unix Oracle instance and a Windows based SQL Server instance? Any help you could provide would be most helpful. We have got this working but only by installing a WIndows Oracle database and using it as a passthrough. I'd really like to remove this from the mix if at all possible.
Thanks in advance.

Does anyone know how to develop a DB link between a Unix Oracle instance and a
Windows based SQL Server instance?Yes. Heterogenous services.
Jeff Hunter has written a nice article on it. He uses Oracle and MySQL but the principles are the same. And of course the documentation has lots of guidance too.

Connect to Oracle database from SQL Sever

Can you help on an issue of connection from SQL Server to Oracle database:
In SQL Server, I create a "linked server" to connect to Oracle database on a different machine. But it will take a unreasonable time (about 30 seconds) to call a Oracle query from SQL Server.

No there are no entries required in the TNSNAMES.ORA
When you are using ODBC for connection, Oracle does not look fo rany enteries in TNSNAMES.ORA file.
Now I am able to connect to both SQL Plus and Forms 6i. But while connecting to SQL Plus its giving an error
Error accessing PRODUCT_USER_PROFILE
Warning: Product user profile information not loaded!
You may need to run PUPBLD.SQL as SYSTEM
Server not available or version too low for this feature
Connected to:
Oracle Open Client Adapter for ODBC 6.0.5.35.0
Microsoft SQL Server 08.00.0534
Also while disconnecting the Windows Program Error comes, and the application closes abruptly.

UD Connect with SQL Sever 2008

Hi,
I created a ud connect for connect with SQL Server 2008 but not working. Message: UDCADAPTERROR::RSSDK|100| Unable to connect to destination.
When I try with SQL Server 2005 work very well.
For both I used Microsoft SQL Server JDBC Driver 2.0.
Someone has an idea.....
Thanks!
Fernanda.

Hi,
I used Microsoft SQL Server 2005 JDBC Driver 1.2 with HotFix JDBC Driver 1.2.
"The customer needs to use our JDBC driver 1.2 in the state of hotfix 12. The customer shall go to the SAP Service Market Place. They shall read OSS note #639702. In that OSS note (SAPu2019s flavor of our KBAs), they find the location for the hotfixed JDBC driver on the SAP Market Place and the exact way how to replace the origin DataDirect driver SAP delivered for a while."
Good Luck!

Fernanda.

Oracle connectivity to SQL Server

I read that Oracle recommends the gateway be installed on the SQL server box for optimal performance. However, if Im running a SQL Server cluster on Wind 2000 server, in an active/passive mode, what is the recommended installation architecture? Should I install it on a third machine, configured to access the active node of the cluster or can/should it be installed on both nodes, but only having the active db node running the active gateway node?
Thanks

Hi,
You have 2 major options:
1. Use Generic Connectivity with your Oracle 9i database running on Solaris. However it requires a proper ODBC-Driver to be installed on Solaris capable of connecting to Microsoft SQL Server
MetaLink DocID: 245549.1 - How to setup Generic Connectivity - HSODBC - on SUN Solaris
Remark: Oracle 9i has been de-supported, should you run into new bugs they wouldn't be fixed by Oracle
2. Install and use the Database Gateway for ODBC 11g on the same machine which hosts the SQL Server database. Usage of this gateway is included in the Oracle database license. DG4ODBC also requires an ODBC-Driver but this one is mostly already present.
Another option would be to install the Database Gateway for MS SQL Server (DG4MSQL) 11g on the same machine which hosts the SQL Server database. However this gateway requires an additional license. The big advantage of this gateway over DG4ODBC is that it supports the two phase commit protocol (distributed updates) and calling of SQL Server stored procedures. Also the dataype mapping is better compared to DG4ODBC.
One thing though; in order for you Oracle 9i database to cooperate with one of the 11g gateways a patch for bug 5965763 on top of 9.2.0.8.0 is required. See also MetaLink DocID: 457808.1 for more details.
I hope this get you going.

DB2 8.1 to Oracle 11g with SQL Developer 3.0

Hi,
I started migrating my DB2 8.1 to Oracle 11g, with SQL Developer 3.0
Basically, I need to migrate TABLES.
I followed these steps:
1) I created a new Oracle database, tablespaces, users, etc.
2) Then, I created both (DB2 and Oracle) connections into SQL Developer 3.0. All works fine.
3) I start capturing one table with the "Copy to Oracle" feature. Done with no errors.
But when I compare the table structure, I see the following problems in Oracle:
a) All fields are NULLABLE = YES. SQL Developer show this field property correctly in DB2: NULLABLE = NO, but not migrated the same!
SOLUTION: All I want is that SQL Developer simply migrating the same value who I have in the DB2. But how?
b) In DB2 I have one field property called COLUM DEFAULT. In Oracle this property is called DATA_DEFAULT. The SQL Developer show this field property correctly for the DB2 tables (for example: 0.0, ' ', etc), but don't migrated the same value! All fields are configured to DATA_DEFAULT = NULL.
SOLUTION: I think this occurs because NULLABLE is migrated with the value YES. Well, all I need is the same above...
NOTE: I tested the SWISSQL DATA MIGRATION software, and it works fine. All tables, field properties and data are migrated sucessfull. But this program is trial version!
Well, I think all of this are BUGS into SQL Developer.
Please, anyone to help me?

Ylram

Welcome to the forum!

I just did right click in the procedure body and found [Debug, Compile for Debug, Compile, Run].

You listed a bunch of things but you didn't say what steps you actually performed and what the result was.
Did you 'Compile'the procedure? until you compile the procedure you can't debug it.
I just created a new procedure and when I select the body it displays in the 'Code' window on the right. But the 'Debug' icon is not enabled because the procedure was not compiled for debug.
When I compile it for debug the 'Debug' icon is now enabled.

Connection to SQL Server Database

I am working on 4.6C. How can i connect to SQL Sever database ? I am new to this type of concept. Kindly do provide some suggessions !!!

Hi,
In general, if we want to hit database directly, we use..
EXEC.
ENDEXEC.
ex:
DATA: BEGIN OF wa,
        connid   TYPE spfli-connid,
        cityfrom TYPE spfli-cityfrom,
        cityto   TYPE spfli-cityto,
      END OF wa.
DATA c1 TYPE spfli-carrid VALUE 'LH'.
EXEC SQL PERFORMING loop_output.
SELECT connid, cityfrom, cityto
INTO   :wa
FROM   spfli
WHERE carrid = :c1
ENDEXEC.
FORM loop_output.
WRITE: / wa-connid, wa-cityfrom, wa-cityto.
ENDFORM.

Getting parsing SP error while migrating SQL Sever 7 to Oracle 8.1.7

Hello,
I migrate SQL Sever 7 database to Oracle 8.1.7 using latest
Migration Workbench + sqlsever7 plugin.
I captured the source database and created Oracle model but some
of straight forward enough stored procuderes didn't pass. I try
manually correct them but still receive the following error
message:' java.lang.StringIndexOutOfBoundsException:string index
out of range:0 ViewLog Window' I check log - not much help
I check all names - non of the exceeds 30 char.
Although, I'm not sure of following code:
@sqlstr='select....'
@sqlstr=@sqlstr+'select...'
exec @sqlstr
Could it be a cause?
Thanks in advance

Issues connecting to sql 2005 database using Oracle sql developer 1.2

I just installed the sql developer and was trying to use the quick migrate to try a migration from a sql server to oracle..
I am getting the following error message when i click on the retrieve database after entering the database credentials
Status : Failure net.sourceforge.jtds.jdbc.driver
I am getting another error message when i click on the 'test' button
Status: Failure - Unable to find driver: net.sourceforge.jtds.jdbc.driver
I downloaded the jtds driver from source forge and i am wondering what I should do to get the sql developer to make successful connections to sql server.
Any help is appreciated.
Thanks

I have the same issue with both version 1.1.3 of the SQL developer and the latest version(1.2.1). I have added the jar file path in tools->preferences->Database->Third Party etc...
I got the jar file from this download: jtds-1.2.2-src.zip
I get this error when trying to connect to an sql server:

NLSRTL Version 10.2.0.4.0 - ProductionOS is AIX 5.3 for Oracle 10 and AIX 6.1 for Oracle 11.
We are currently in the process of migrating some applications from Oracle 10 to 11. Our admins have setup a new development system for us with an Oracle 11 instance. Regarding performance the new system behaves more or less the same than our old, e.g. when executing SQLs we notice hardly any performance differences and those we find are slightly in favour of the new system.
But now we discovered that the time it takes to establish a database connection via SQL*Plus is longer on the Oracle 11 system. Running the following code
sqlplus -s user/pw@database <<END
quit
ENDa thousand times takes ~60s under Oracle 10 but ~140s under Oracle 11. This may not seem much but we are running a test framework consisting of a bunch of shell scripts where several thousand connections are openend via SQL*Plus to execute some SQLs, so that even this small time difference results in rather huge difference in total runtime. The SQLs themself require roughly the same time in both databases, as already mentioned above they are in fact slightly faster in Oracle 11.
To analyze the time difference I ran a trace for the connect with the following parameters in sqlnet.ora
TRACE_LEVEL_CLIENT=4
TRACE_UNIQUE_CLIENT=ONand found out that there is a time difference of about 70ms during the connect handshake:

(1) [22-MAR-2013 13:33:40:618] nscon: got NSPTRS packetAny ideas what could be the reason for this time difference? Something in our network configuration or something else?

With local connections - I do not think a TCP packet send from an IP to the same IP, leaves the interface as an actual wire protocol/signal. If I'm correct, then running local connection tests will be mostly useless in checking the actual network infrastructure.
Tests 3 and 4 should be showing the same connection times as the same physical network infrastructure is used - only the direction is reversed in the tests.
I would assume that port settings on the switches and interface settings on the routers treat packets equally in both directions between 2 servers. But this could in part explain the problem if this is not the case. In a case of a router for example, the 1st test's ingress interface is the egress interface of the 2nd test (and vice versa). Configurations can differ substantially between interfaces on the same router. Likewise if there is a firewall - as different rule sets are applied in each test and these rule sets could differ.
So I would not be too quick to state that this is definitely not a network problem. But I agree that based on the small percentage difference (assuming comparable tests), it does not look like a network issue.
The next step is to determine what the delay is between the listener accepting the client connection, and the connection being serviced by a dedicated server process.
This will require listener tracing - tracing the time from when the listener accepted the connection (and parsed the TNS connection string), to handing off the connection to the dedicated server process.
As a comparison test, you can also test shared server connections. Dispatcher processes (of the db instance) register themselves with the listener. The shared server client hand off is thus done to an existing server process - no need for the Listener to make a kernel call to load and initialise an executable image.
Shared connections are typically faster than dedicated connections in this respect.
If there is a major time difference, then it means some kind of issue with the listener dealing with dedicated servers as oppose to dispatcher hand off's. As both connections would have had very similar network transit time - which means the connection time difference is related directly to dealing with a dedicated server connection request and hand off.
You can also substitute the oracle executable with a wrapper - and troubleshoot the actual dedicated server startup. I've only done this with Oracle XE 10.2 though and with local IPC connections. Unsure how robust this will be for testing purposes via TCP using 11g.

Connecting to SQL 2005 from Oracle error

I have an Oracle Database and SQL Database on the same server and wants to use odbc to connect to the SQL 2005 database and query tables of my choice.
I did configured the ODBC correctly and called the DSN TSH_ARCHIVE. I have tested it and it works great. But each time I run the following query I get error:
SQL> select count(*) from BALANCES_HS@tse_archive;
select count(*) from BALANCES_HS@tse_archive
ERROR at line 1:
ORA-12154: TNS:could not resolve the connect identifier specified
Any suggestion and help will be greatly appreciated.

Hi,
Thanks for the files.
There are some problems with the configuration.
listener.ora -
LISTENERTSE_ARCHIVE =
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=tcp)(HOST = xxxxx.ita.doc.gov)(PORT=1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=

(PROGRAM=hsodbc)
(SID_DESC=
(SID_NAME=tpisdb06)
(ORACLE_HOME=J:\app\product\11.1.0\db_2)
This should be -
LISTENERTSE_ARCHIVE =
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=tcp)(HOST = xxxxx.ita.doc.gov)(PORT=1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
SID_LIST_LISTENERTSE_ARCHIVE =
(SID_LIST=
(SID_DESC=
(SID_NAME=TSE_ARCHIVE)
(ORACLE_HOME=J:\app\product\11.1.0\db_2)
(PROGRAM=dg4odbc)
(SID_DESC=
(SID_NAME=tpisdb06)
(ORACLE_HOME=J:\app\product\11.1.0\db_2)
The SID_LIST_LISTENER needs to match the actual listener name and the program for 11g DG4ODBC is called dg4odbc and not hsodbc.
tnsnames.ora -
TSE_ARCHIVE =
(DESCRIPTION=
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = TSE_ARCHIVE)(PORT=1521))
(CONNECT_DATA =
(SERVICE_NAME = TSE_ARCHIVE)
(HS=OK)
The HOST name - TSE_ARCHIVE does not match the HOST in the listener, so it should be -
TSE_ARCHIVE =
(DESCRIPTION=
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = xxxxx.ita.doc.gov)(PORT=1521))
(CONNECT_DATA =
(SERVICE_NAME = TSE_ARCHIVE)
(HS=OK)
I've changed the actual name to xxxxx so replace that with the name in the original file.
Change the files, stop and start the listener then try again.
If you still have an ora-12154 error then send the output from the following SQL -
select db_link, host from user_db_links; <=== as the user getting the error
and
select db_link, host from dba_db_links; <===== as a DBA user

There are 2 gateway - the commercial Database Gateway for Ms SQl Server which requires a license and the Database Gateway for ODBC which is for free. The license for DG4ODBC is included in your database license. You only need to install a suitable ODBC driver on your Linux box (for example use the MS SQl Server ODBC driver for Linux - details can be found here: http://www.microsoft.com/en-gb/download/details.aspx?id=36437 ). and then configure the gateway using the My Oracle Support Note:
How to Configure DG4ODBC on 64bit Unix OS (Linux, Solaris, AIX, HP-UX Itanium) to Connect to Non-Oracle Databases Post Install

Connecting to SQL Server from Solaris using Perl & Oracle.

Hey All,
Using the DBI.pm provided by the default Perl package that comes integrated with Oracle server, I am being able to connect to the Oracle database through Perl.
But is there a way I can connect to SQL Server through Perl using any package provided by Oracle like ODBC or something else (on Solaris)
I am using following version of Oracle server on Solaris 10
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production
TIA
Parag

The problem is I cannot install any third party package but I found something. Have a look at this:
bash-3.00$ pwd
/opt/oracle/product/10.2.0.4.0/perl/lib/site_perl/5.8.3/sun4-solaris-thread-multi/Win32
bash-3.00$ ls -l
total 10
-rwxr-xr-x 1 oracle dba 4532 Jul 7 2004 DBIODBC.pm
bash-3.00$
Will explore more and keep you all posted.
Cheers,
Parag

Oracle error: java.sql.sqlrecoverableException: Closed Connection

need help on this closed connection
getting oracle error: java.sql.sqlrecoverableException: Closed Connection when running a java application using tomcat api to oracle 11g database EE 11.2.0.3.0 on windows 2008 R2

Hi,
I understand that you have raised a SR for this issue which is being worked upon by our team.
Additionally, please note that the "Closed connection" error typically happens because a timeout parameter of some sort timed out the connection. This could be a parameter specified in your datasource, in your application code, or network (such as a firewall).
You may also want to -
1. check your database to be sure it is not timing out connections.
2. Make sure your network is running efficiently and that it can provide fast connections,
3. Check your Java Virtual Machine (JVM) Code Cache For Oracle Enterprise Data Quality for any memory related issues
