Backup oracle transparent gateway

HI
I have a oracle transparent gateway for mssql server.
Which archives we must backup?
TIA
[email protected]

I'm not sure that I follow the question. What archives are you talking about?
Are you talking about archived log files? If so, you back up whichever logs your backup & recovery plan calls for-- this would be completely independent of your use of the transparent gateways.

Oracle Transparent Gateway for MS SQL Server

Hello,
I successfully installed the Oracle transparent Gateway for MS SQL Server for Oracle 8i. Now I am doing the same for Oracle 9i.
Does anyone know how to 'create a new gateway service' on 9i???
This is how you would do that on 8i on the Windows box...
1) At the MS-DOS prompt, enter:
> set GTW_EXE=TG4MSQL.EXE
2) To create a new gateway service name, enter:
> GTWSRV73 sid -CREATE | MORE
-where sid is the gateway sid.
Does anyone know how to do those steps for 9i Oracle Transparent Gateway?
Thank you.

Oracle transparent gateway sql server ORA.28511

Hello,
I tried to install the gateway for ms sql server and failed, can anyone help me?
the 1. computer - database server is a hpux with oracle 8.1.7
the 2. computer - gateway computer is a win 2k with oracle transparent gateway 9.0.1
the 3. computer - Sql Server is a Computer with WinXP and SQL Server 2000 SP3
what i did:
-i created an entry in tnsnames.ora at the database server
-i cerated an entry in listener.ora at the gateway computer.
-i created the file inittg4nidb.ora (tg4nidb = SID)
-i created a database user at the sql server
-i created a database link in oracle
then i tried to select data from the sql server database and i got the following message:
SQL> select * from tab_ScriptCoordination@thomas1;
select * from tab_ScriptCoordination@thomas1
ERROR at line 1:

the listener seems to be ok (i get an new entry in listener.log when i execute a selectstatement in sql+), also i can see the program tg4msql in the taskmanager of the gatewaycomputer after executing a select.
there must be something wrong in the file inittg4nidb.ora

Thomas,
There is not enough information for me to figure out why you are getting this error. Basically the error indicates that the gateway has crashed.
Please set the HS_FDS_TRACE_LEVEL = DEBUG and take a look at the trace file.
Also send the tnsnames entry as well as the listener.ora

Are the Oracle Transparent Gateways SAP approved

Gentlemen: Thanks in advance for your reply. I am new on this gateway world and I am trying to find the best solution for us.
Situation ... DB Migration of SAP 4.5B from MSSQL to Oracle8 in Sun Solaris (No problem with this).
We run a VB application that connects to SAP using SAPComm to read from SAP and update, asl well.
Problem: We will do the migration but the developer of the application in VB may not be open to change their coding, and we found the option of replicating db tables from Oracle to MSSQL, once we migrate, with the Oracle Gateway, which produce something transparent to the VB application.
Questions:
1. Does SAP approve this kind of accesses/replications to their DBs without us affecting our license agreement with them? I should ask this question to SAP, but if you know already, that will defenitely help?
2. I understand this tool (Oracle Transparent Gateway) is available as of Oracle9i. Our migrated SAP system will be running on Oracle8, but it is my understanding it does not matter the version of Oracle we are running our db, because what we procure is the Oracle9i to be installed separately to interact with both SAP (Oracle8) and MSSQL. Is that right? Could I build that scenario? If yes, how much is for the Oracle9i license. Should acquire it through SAP (I guess not)?
Thanks,
Juan-Carlos

You can use Oracle Streams to replicate from Oracle to SQL Server. This is a feature of Oracle 9.2.
This feature uses the Oracle Transparent Gateway for SQL Server to communicate between Oracle and SQL Server.
This is licensed separately from the database. Oracle 8 can communicate with Oracle 9i using DB links.
You can purchase a license for the each of these products at http://oraclestore.oracle.com/

Any benefits of Oracle Transparent Gateway to connect to MSSQLServer ?

What are the benefits of Oracle 10G's Oracle Transparent Gateway to connect to MSSQL Server ?

Please be aware all gateways including the free component hsodbc up to release 10.2 have been desupported by 15th of Marcg 2008 and customers should use the follow up products.
The follow up product of TG4MSQL is Database gateway for MS SQl Server v11 and the follow up product of HSODBC is Database gateway for ODBC V11. The V11 gateway are certified with older Oracle database - but you might apply a gateway compatibility patch to the Oracle database release.
There are a lot of differences between DG4MSQL (TG4MSQL) and DG4ODBC (HSODBC):
- DG4MSQL supports many more functions it can directly map to SQl Server equivalents - DG4ODBC only suppors a few functions it can directly map to the equivalenst of a foreign database and all other functions are post processed. Post processing means ALL records from the remote table are fetched into the Oracle database and the result is then processed locally. Depending on the amount of data in the foreign table it might take a while
- DG4MSQL can call remote stored procedures
- DG4MSQL can participate in distributed transactions. This for example allows you to pass data changes in an Oracle table directly in the same transaction to the SQL Server side using triggers. Or you can also use STREAMS to replicate data between both databases.

Query over Oracle Transparent Gateway on DB2 hangs the session

I am on Database release 10gR2 using the Oracle Transparent Gateway (v9) installed on a DB2 i*series machine.
The Oracle database is located in the same data center as the DB2 database. When I issue very simple queries such as select count(*) from t, I get a result immediately. However when I issue something like select * from t, I very rarely get any rows back (I will sometimes 39 out of 4000) and the session appears to hang. Our DB2 administrators report that everything looks ok on their end. It's like the query is executed in DB2 but the gateway has trouble replying to the Oracle DB
As a side note, the hung session prevents the database from shutting down but does not prevent the database from closing some processes while trying to shutdown (e.g. J000, MXXX, etc.). This results in an open database with missing processes (non critical).
I think this is a network/firewall issue, has anyone had any similar experiences with the gateway? How can I diagnose the problem?
I should note, other Oracle databases in different locations (and different versions) do not have a problem when running the same queries.

If I remember correctly the V9 TG4DB2/400 was not certified with Oracle database 10gR2; only 10.1. See also Metalink certify page which states:
Operating System: IBM AS/400 Version V5R1 - V5R3
Oracle Transparent Gateway for DB2/400 Version 9.2.0
Oracle Database - Enterprise Edition V10 Version 10g
Status: Desupported
Side Note: the certify version states 10g; this means 10gR1; not 10gR2.
You can crosscheck it while checking out the V10.1/2 gateway certification which explicite lists 10gR2.
So it would be interesting if any 10gR2 database can successfully query the table.

Difference between Oracle Transparent Gateway and Golden Gate

Hi Guys
Could you please clear the confusion, What is the difference between Transparent gateway and Golden gate? are they same? In which situation which one to use?
Thanks in advance

So you mean if an application (designed to work with oracle only ) can actually access SQL server or DB2 without any modificaton. If i am having transparent gateway on top of DB2 or SQL server ??You caught me. I should have used different words.
No. TG is a mechanism to query other RDBMS from Oracle. GG is a mechanism to have replication between any RDBMS.

Oracle Transparent Gateway

Which gateway product will allow me to connect oracle v7.3.2 to a SQL 2000 Server? Where can I download an evaluation copy?

I don't believe the transparent gateways are downloadable. I'd contact your sales rep. They may also be incluided in the CD packs. -Kevin

Is Transparent Gateway (4.1.1.1) supported in Oracle 8i

Hi We are having some RDB databases running in conjunction with Oracle 8.0.6.0.0 databases. We have installed Oracle 8.1.7.0.0 recently, and I am wondering if this 8i version is supporting Oracle Transparent Gateway ???
I ran an export in the existing DB 8.0.6, and I get this error during the import to 8.1.7.0.0:

This "GTW_SQL" is a object resides on serverside of the gateway and not in the databases (8i or RDB).
I am lost at this point. Any help would be of great use, and appreciated.

Oracle access tables in SQLServer through Transparent Gateway

HI,
I want to access tables in SQLServer2000 through Oracle Transparent Gateway, but i could not get the resqult when I excute sql " select * from mytable@tg4msql".
everthing seems all right and when i use " *tnsping tg4msql* ", it also return OK:
Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)
+(HOST = 192.168.255.10)(PORT = 1521))) (CONNECT_DATA = (SID=tg4msql)) (HS= OK))+
OK (20 毫秒)
but when i excute sql like " select * from mytable@tg4msql ", it does't return anything, just keeps quering till I kill my plsql.
it seems oracle tries to connect to SQLServer through database link but fail.
And i check Transparent Gateway debug log : ORACLE_HOME\tg4msql\trace\tg4msql_agt_964.trc,
the log stops when it gets the logon name.
thanks for answers~

Transparent gateway to Sybase: connection error

I have been trying with little success to set up a transparent gateway to a sybase server.
The gateway is an NT 4 workstation, with an oracle server 8.1.7 installed. The sybase server is an ASE 12.0 on a Solaris 8 box.
Are these versions of the products supported? In the gateway documentation only Sybase 11 is mentioned...
Moreover all the examples/schemas given refer to an installation of the gateway on the same machine as the sybase server, whereas in my case the gateway is installed on a separate machine (but it is also stated that this configuration is allowed, provided a sybase client is installed togheter with the gateway).
From what I can make of the error messages / trace files, the problem lies in the gateway not finding the sybase server. But from the sybase client installed on the gateway machine I can connect to the same remote sybase server without hassles, so the sybase client is configured correctly.
Thanks for help,

Gaetano,
The supported products that we list in the manual is only what we have tested at print time. However we update our certification matrix regularly.
Please refer to the certification matrix on Technet.com ( http://otn.oracle.com/products/gateways/pdf/certmatrix2.pdf) for the latest certified configurations.
It looks like you have installed the gateway in the same Oracle home as the database. With v8.1.6 of the gateway this is not possible. With v9.x onwards this is possible.
You can either reinstall the gateway in another Oracle home or upgrade to v9.x.
I recommend that you upgrade to v9.x, since v8.x will be desupported shortly.
As of v9.x the Sybase gateway is located on the database CD and you can install it by doing a custom install.

Oracle Transparent Gaeway Query

Hello Experts,
I am looking for a help here for the Oracle Transparent Gateway :
My objective is :
I have an EBPP application running on Jboss with SQL Server 2005.
Here are the details:
JDK 1.4
JBoss 3.2.5
SQL Server 2005
I would like to migrate it to Oracle 11g R2. I dont want to touch my application to make it compatible with Oracle. I would like to keep the SQL server drive and queries as it is. As far as i see, I have only one option.
One Go fo Oracle Transparent Gateway Way -
Migrate whole database of SQLserver 2005 to Oracle.
Shutdown the SQL server and install Oracle transparent gateway
Point the application to oracle transparent gateway.
Application will talk to oracle database via oracle transparent.
Upgrade application for oracle
Going with this, i have to upgrade so many things like JDK, JBoss and whole application.
Please advise, if you see a better approach to tacke this issue.
Thanks
Regards,
Zeeshan Qureshi

One Go fo Oracle Transparent Gateway Way -
Incorrect. The Oracle Transparent Gateway is for the Oracle server to connect to the foreign server via a database link. This enables Oracle SQL and PL/SQL code to access a foreign database from the current Oracle database, by using a heterogeneous database link.
Sybrand raised a critical issue. Oracle != SQL-Server.
There are some fundamental and core differences between the two products. This means that a SQL-Server application will not be able to use Oracle optimally and scale accordingly - and that the application needs to be refactored.
What about this so-called +"the database is a black box+" approach that allows the database layer to supposedly be swap in and out for different database products - without having to touch the application?
A bunch of bull. For the black box approach to be used means developing the application to the very lowest common denominator that are supported by all RDBMS products. The lowest common denominator changes the RDBMS into a simplistic record-and-file architecture - using less than 5% of the actual capability of the RDBMS product. A total waste of technology and costs. One just as well could look at not using a RDBMS at all and simply roll the basic functionality in the app layer itself.
Your basic problem in my view is a conceptual one.
Applications are a dime a dozen. New code gets bashed out all the time. Applications are swapped in and out. Are upgraded. Are changed. There is a saying that if an application does not change, it is dead as it is no longer servicing business needs and growth and changes in the business and the market.
What remains fairly consistent and stable and constitutes the core, is the data. Simple example. What is important? The spreadsheet software or the spreadsheet data? Whether the spreadsheet s/w is Excel or Open Office or whatever - that is not what is important for the sales guy doing his sales projections. The actual spreadsheet and data are critical.
So it is about the data. Not about the application.
So your task is to make sure that the data layer is robust and consistent. Is performant and scalable. Is reliable. Is secure. And then put the application on top of that data layer.
It is not designing the application totally separate from the data layer and expect to simply swap one data layer for another and that the application will still fit and use that data layer correctly and optimally. (unless your an ISV doing a truly independent RDBMS s/w product, in which case you need to design and write a very large and very complex data access layer that can deal correctly with the specific data layer in use - and no, smelly stuff like Hibernate is not it)

Oracle 10g connectivity with sql server 2000 through oracle transpa gateway

dear gurus.
i am to connecto oracle 10g with sql server 2000 through oracle transparent gateway.
i have installed transparent gateway and proper configured. also link is created.
but when i execute query "select * from city@inventory" , so an error displayed.
ORA-12500: TNS:listener failed to start a dedicated server process.
kindly suggest me what could be the cause.
regards,

if the listener fails to spawn a dedicated server process it is commonly indicating an issue with the listener. So posting the listener and also a listener trace including a description of the env where you installed the gateway into which directory would be helpfull. Please keep also in mind if you have for example a 10.2.0.3 database and you install into this directoty a 10.2.0.1 gateway you have to reapply the patchset again do get consistent file version.
So please describe more detailed your env.

How to know Transparent gateway version

dear all,
Facts:
WIN 2008 AND MSSQL SERVER 2008
AIX 5.3 AND ORACLE 10.1
how i know the version of Oracle Transparent Gateway from :
- Oracle MS SQL Server 2008
- Oracle 10.1
how can i view that ???
thanks a lot !!!

Sorry, but it is not really clear what yo mean with:
how i know the version of Oracle Transparent Gateway from :
- Oracle MS SQL Server 2008
- Oracle 10.1
You can check the vesion of an installed gateway using Oracle Universal Installer which can list which products are installed or you can use opatch lsinventory -detail.
You can also check the listener - it contains PROGRAM=<executble> and now type the name of the executable on the command line. It will now report which gateway and which version you've installed.
If you're interested in which gateway can be used - then the only supported release is 11g which is certified with Oracle 10.1.0.5 + an additional gateway compatibility patch.

Oracle 9i on LINUX Transparent Gateway for SQL Server

Does anybody know if there is a Transparent Gateway available for Oracle 9i on LINUX to connect to SQL Server? I have run the installer and cannot seem to find the install options for any Transparent Gateways. I am familiar with their location in the universal installer as I have installed the Oracle/SQL Server Transparent Gateway with Oracle in WinNT. Perhaps Transparent Gateways for Oracle/LINUX are not available?
Thanks in advance.

I have the same issue - we want to upgrade our 9.2 to 10g Linux, and need to maintain connectivity to some legacy sqlserver databases. I can't find any mention of tg4msql for linux. What gives? Anyone know the answer to this? thanks, michael
