Connect Oracle 9i to SQL Server: platform incompatibility

Hi,
we want to connect an Oracle 9.2.0.4.0 - 64bit Production to a SQL Server.
The Oracle DB is on a HP-UX Itanium 64bits machine.
The SQL Server is on a WIN2000 machine.
Our first choice to get them connected was an ODBC and HS.
However, as far as we know, there is not HS for our platforms combination.
We have also tried to use another Oracle BD in a WIN machine as a middle tier.
Single queries work fine, but advance plsql blocks render in several errors (some due to db version, others to the way the oracle manager works)... so this solution also fails.
We have read about Transparent Gateway. But since it uses HS, we are not sure our platform combination is supported. Moreover, on the whitepaper is said "stored procedures are not supported", which it is a hard backdraw.
Any suggestion or workaround?
Thanks in advance!
Alberto.

You can use TG4MSQL, the Gateway to SQL Server.
The big advantage of the gateways is: they are independant from an Oracle db.
This means, you can run an Oracle DB on machine A, have the gateway installed on machine B and run the foreign database on a 3rd machine!
The TG4MSQL is only available for Windows based 32bit platforms, so in your case you can install the gateway on the SQL Server machine or -if you don't have access to it- on a 3rd machine running MS Windows operating system.

Connecting Oracle(64bit) to SQL Server(32bit) with heterogeneous serv ODBC

Hi,
We are planing the migration of 32bit Oracle 9.2.0.8 (MS Windows Server 2003 EE SP1) to 64 bit Oracle 10.2.0.4 (MS Windows Server 2003 Standard x64 Edition SP2).
We have tested the migration using export/import procedure, and everything passed ok.
The problem is because the database we are planning to migrate (32bit) using Oracles heterogeneous Services ODBC agent in connection to 32 bit SQL Server 2000. When we have tried to implement that on 64bit 10.2.0.4 oracle we always get the message:
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
Then we looked up the metalink and find the document: Is Generic Connectivity Available On Linux Or Windows 64-bit Platforms ? [*ID 361676.1*]
Is there any way to make the connection between 64bit Oracle 10.2.0.4 and 32bit SQL Server using system DSN within the Windows ODBC Data Sources with choosing the SQL Server driver?
The option with Database Gateway for ODBC (DG4ODBC) isn't free.
Thanks

Hi everyone
As far as I am aware, you need to install the Discoverer EUL into an Oracle database and then use an ODBC connection to SQL Server. This is because Discoverer has hooks into the Oracle database and is looking for features that only exist in an Oracle database. If you are using an Infrastructure, which is mandatory when using 4i, you can use that database to store your EUL using an ODBC connection over to SQL Server.
I hope this helps
Best wishes

Connect oracle forms to sql server 2000

Kindly tell me what kinds of scripts i have to install in SQL Server.

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.

Hi,
As far as I know this is possible using ODBC and Oracle Open Client Adapter (OCA), but I do not know the details and the howto's.

Connecting Oracle DB with SQL server

I need to connect an Oracle Data Base to a SQL Server throught a BPEL process. Somebody knows about a TUTORIAL or maybe other guide.....pls this is urgent.
Thanks

Reading you post, I asssume you want to select data from an Oracle database and pass this information to a BPEL processs. This process will store the data into a SQL Server database.
Create BPEL process, with two partner links, using the DB adapater. One partner link is using the Oracle databas, the other one SQL Server.
Therefore you must add/change your oc4j-ra.xml, to add an Oracle DB connection and an SQL Server connection: The file can be found at

Oracle 10g to sql server 2005 - how to setup

Hi,
I have been searching on how to setup a connection from oracle 10g to sql server 2005 and i have to admit i am struggling a bit.
I have read about Heterogeneous Services and Database Gateway but we really dont want to fork for licence fees so it looks like i have to investigate HS.
My environment is:
10gR2 Linux 32 bit
SQL Server 2005 32bit.
Would someone be able to provide me with a list of steps to help me get this setup?
Thanks.
B

Hi,
If you don't want to pay for any licence fees then you will have to use the 11g Database Gateway for ODBC (DG4ODBC) which is included in your RDBMS license.
You need to use the 11g versions because all previous gateway versions have been desupported for some time. The latest version is 11.2.0.3 which can be downloaded from My Oracle Support as -
Patch 10404530: 11.2.0.3.0 PATCH SET FOR ORACLE DATABASE SERVER
and download -
p10404530_112030_platform_5of7.zip
- this is the Gateway media pack and has everything needed for a standalone gateway install.
This version is certified the following RDBMS versions - 10.1.0.5 + RDBMS patch 5965763, 10.2.0.3 + RDBMS patch 5965763, 10.2.0.4, 10.2.0.5, all 11.1 versions, all 11.2 versions.
You have 2 choices about where you can install it and it would be better to install the gateway into a new and separate ORACLE_HOME from any existing Oracle installs -
1. On the Linux 32-bit platform where the RDBMS is running. If you install it here you will need to supply a third party ODBC driver. The only free one I am aware of is from FreeTDS but there may be others. There can be problems with the FreeTDS so another one may be preferable but these usually require a license fee.
See this note in My Oracle Support -
How to Configure DG4ODBC on Linux x86 32bit or on HP-UX RISC (DG4ODBC 11.1 only) to Connect to Non-Oracle Databases post install (Doc ID 466228.1)
2. Install DG4ODBC on the Windows platform where SQL*Server is running. If you install on Windows then you will be able to use the Microsoft SQL*Server ODBC driver which should already be installed. See this note on My Oracle Support -
How to Setup DG4ODBC (Oracle Database Gateway for ODBC) on Windows 32bit (Doc ID 466225.1)
If you don't have access to My Oracle Support you will need to contact someone in your organisation to access the notes for you or review the gateway documentation -

Kindly pls help me.
Thank you.
Avelyn

1.Make certain that a current version of the oracle client code is installed at the distributor”, please install corresponding version of Oracle
Client tools on Distributor Box
2.Are you able to connect to your Oracle server from the Distributor Box?if so,Distributor
box needs to have Oracle client tools installed on it before you can setup replication , I hope you have installed the Oracle client tools on Distributor Box. If yes, check if using SQLPlus you can connect manually to Oracle server or not from your Distributor
Box.
Moreover,Please refer the below
Before attempting to configure the Oracle Publisher, SQL Server verifies that SQL*PLUS is accessible through the system path on the Distributor. If SQL*PLUS cannot be loaded, the following error message is shown:
"Unable to run SQL*PLUS. Make certain that a current version of the Oracle client code is installed at the distributor."
Try to locate SQL*PLUS on the Distributor. For an Oracle 10g client install, the name of this executable is sqlplus.exe. It is typically installed in %ORACLE_HOME%/bin. To verify that the path of SQL*PLUS appears in the system path, examine the value of the
system variable Path:
Right-click My Computer, and then click Properties.
Click the Advanced tab, and then click Environment variables.
In the Environment Variables dialog box, in the System variables list, select the Path variable,
and then click Edit.
In the Edit System Variable dialog box: if the path to the folder that contains sqlplus.exe is not present in the Variable
value text box, edit the string to include it.
Click OK on each open dialog box to exit and save changes.

What are the Basic Differences between Oracle and MS-SQL server Database?

Hello,
anybody pls Guide me about the Differences between Oracle and MS-SQL server Database.and also IBM Databases also
Regards,
Balaram

SQL Server only works on Windows-based platforms, including Windows 9x, Windows NT, Windows 2000 and Windows CE.
In comparison with SQL Server , OracleDatabase supports all known platforms, including Windows-based platforms, AIX-Based Systems, Compaq Tru64 UNIX, HP 9000 Series HP-UX, Linux Intel, Sun Solaris and so on.
The SQL Server advantages:
SQL Server holds the top TPC-C performance and price/performance results.
SQL Server is generally accepted as easier to install, use and manage.
The Oracle Database advantages:
Oracle Database supports all known platforms, not only the Windows-based platforms.
PL/SQL is more powerful language than T-SQL.
More fine-tuning to the configuration can be done via start-up parameters.

Please help.

Thanks for your response, it got me closer to my goal. I'm still facing one problem:
Let me explain what I need to achieve
Purpose
Execute an Oracle stored procedure which in turn executes a stored procedure on remote SQLServer which updates local tables on that SQLServer.
Observations
The execution of both procedures completes successfully. However, an explicit COMMIT statement must be issued on the Oracle session which initiated the transaction before any data could be read from the SQLServer updated table.
The following is test exercise for proof of concept.
PL/SQL code
declare
out_arg integer;
ret_val integer;
begin
out_arg := 0;
ret_val := "dbo"."ZZZ_SP"@DBLINK_SQLSERVER(10, out_arg);
dbms_output.put_line(to_char(out_arg));
end;
SQLServer code
ALTER procedure [dbo].[ZZZ_SP] (@arg1 integer, @arg2 integer output)
AS
begin tran tran1
insert into dbo.PA01LOG(msg) values('ddd')
commit tran tran1
set @arg2 = @arg1 * 100
select -1
GO
I have put the Oracle gateway in Single_Site mode to avoid two phase commit. I want SQLServer to be able to run its own transaction management. I don't want Oracle to be responsible for completing the transactions which take place within SQLServer.
I fear there might be a gap in my knowledge.
Any ideas why I need to issue a COMMIT in Oracle session to release the lock from SQLServer table?
Thanks

Oracle 8i vs SQL Server 7 or 2000

Can anybody provide a link or information about what is the best choice to choosing Oracle 8i or SQL Server? I want a technical answer not based on market share or bias.
I have been an oracle DBA and developer for 5 years. Reading up on SQL Server,it seems very powerful as well as Very cost effective compared to Oracle 70% cheaper in some cases.
I am currently researching the back end and front end tools needed for a internal Application system:
20Gig Minimum sized database
80-100 Simultaneous Users
Database server on NT4.0/2000
Any information would be very helpful
Please email to [email protected]
and/or post info.
Thanks

To balance the equation a little bit:
well, here goes the technical difference between sql svr and oracle8i db server:
1. SQL Server has much more rich, intuitive development tools. I find the Oracle tools a bit antiquated and clunky.
2. "control file management is there in oracle. >> BUT NOT IN SQLSVR." Never had the need to "manage files" from the DB, so I'm not sure of the point here.
3. You can manage partitions in SQL Server.
4. Oracle is tied to Java whereas SQL Server is more VB friendly and has JScript support.
5. SQL Server built extensions to TSQL (like PL/SQL) to support direct return of XML in a very simple manner. I'm still swinning through
6. "Operating System authentication is there in oracle. BUT NOT IN SQLSVR." This is just plain wrong. You can authenticate at the OS or DB level in SQLServer.
7. SQL Server does replication including merge replication.
8. Building data warehouses, mining, datamart, MTS, DSS, OLTP is heavily supported in SQL Server.
9. SQL Server introduced the self-tuning database making the administration very simple.
10. SQL Server supports clustering, warmbackups, etc.
11. I can show you several ways to backup/restore and all are very fast.
12. SQLServer2000 has all of the development features of Oracle (and then some) for a fraction of the cost.
13. Oracle's high-end features are better and more complete, and it works on more platforms.
My choice as a developer in a Win2000/NT type environment is SQL Server hands down. Big companies with lots of data have a tougher choice. I think Oracle is more "big iron" and high-end admin friendly, and SQL Server is more developer, self-maintaining, and pocketbook friendly. I depends upon what's important to you.
ALL ABOVE INFORMATION IS BASED ON MY EXPERIENCE WITH SQL SERVER FROM 1996 TO PRESENT.

Oracle Vs Ms Sql Server to handle around 6-7 Terabytes of data

I am considering Oracle 11G to handle around 6-7 Terabytes of data. This data will get accumulated over a period of 8 Months. Any data older then 8 months is purged out of the database.
Some of my MS SQL DBAs are saying SQL server offers similar performance at a very low cost. Is this really true? On What basis or parameters I can compare Oracle with MS SQL Server to nullify the price advantage?
I am not looking for ease of development, I am purely looking in terms of handling the huge data and still be able to provide good performance. Apart from performance if there is any parameter which makes any difference then please highlight.

As with any database requirements tend to drive the best technology to utilize.
I have run Oracle and MS SQL Server as well as MySQL and PostgreSQL.
If you are looking to support a fairly large user based on a database that is 6-7 TB is size where a good portiion of the data is subject to access then there is really is no comparison. Oracle does a much better job of handling large user bases with large data sets then MS SQL Server or MySQL at least based on my experience with them.
MySQL works very well for average user bases and smaller databases where the amount of data accessed is small. In other words you can have 6 TB of data and if you only frequently access 5GB of it then MySQL will work pretty well. If a large portion of the data is accessed all the time by many users you will struggle with MySQL. Most databases in MySQL I ran had issues at user bases of a few hundred with a database size of around 100G-200G, now my main expertise is in Oracle so there may be ways in MySQL to address this, but not easily as normal research and experiment channels did not yeild good results for me.
I have had a MS SQL Server databases with thousands of users fall on it face with a database only 20GB in size, its was completely CPU bound with 8 CPUs, then moved the database to Oracle with minor code changes to accommidate the differences between Oracle and SQL server using the same hardware specs and CPU was a steady 50% for the same work load and basically the same application.
I have found the capabilities of Oracle for large data sets and large users provide advantages that the other databases just did not offer or did not do well enough to overcome. Does not mean that Oracle is perfect, or the other databases are bad, but there are a lot of options and capabilities in oracle the I can take advantage of not to mention if I need to I can run on high end Unix hardware and goto 64CPU dozens of I/O channels, etc. I can not do that with MS SQL Server as Windows is my only option and the intel platform just does not hit the capabilties of higher end Unix Hardware.
When deciding the database to use cost should be the last factor used. If the database will not do what you need it to do then low cost does not help you. Deteremine the needs and requirements and then examine the database features and capabilities to determine what might work best for your situation. If it is a critical business function and you need the caddie then your business will pay for the caddie, it if needs a malibu then pay for the malibu or if it needs the yugo then pay for the yugo. Implement the right technologies where you need them. However there is something of an advantage to limit the number of technologies you will need to support as a jack of all trades never becomes an expert and that in of itself can be costly when trying to overcome issues developed by limitations of a database technology.
