Accessing SQL Server Data From Oracle Developer 2000 Apps
Feb 17, 1999
Hello there
I have a customer that wants to start using SQL Server 7.0 instead of Oracle, but they have a lot of Oracle applications (made in Developer 2000 and Forms). Due to the big effort needed to convert those applications (to Visual Basic), they want to be able somehow to migrate only data from Oracle to SQL Server, and then use some tool that will allow them to use the same applications with the SQL Server 7.0 engine.
I found on the "SQL Server Developer's Kit" a document describing the process of migrating data and applications from Oracle to SQL Server. There is a mention to an Oracle tool called "Oracle Gateway to SQL Server" that will translate calls received by the Oracle engine to the SQL Server engine, but this approach will still require the existence of Oracle servers (which is the thing the customer no longer wants).
The second option mentioned on that document, and the one that seems more attractive, is the use of Oracle "Open Client Adapter" (OCA) that will allow Developer 2000 applications to communicate directly to SQL Server via ODBC. However, I have been unable to find (on the Oracle site) any documentation regarding this tool.
Has anynoe heard or used such tool (OCA) ? Any comments, tips, drawbacks, experience you could share ? Any other idea on how a thing like that could be accomplished ? Perhaps a third-party application that can act as a gateway between the Forms app and ODBC/SQL Server, or that will be able to generate VB code from a Developer 2000/Forms app...
Any help will be appreciated.
Please respond directly to me, as I am not a member of the distribution list.

we recently got a scenario that we need to get the data from oracle tables which is installed on third party servers. we have sqlserver installed on ourservers. so they have created a DBLINK in oracle server to our sqlserver and published the DBLINK name.
what are the next steps that i need to follow on my sqlserver in order to access the oracle tables ?

We are running SQL Server 2000 SP3. We have linked servers in use thatwe use to access Oracle tables.Recently the claim has been made that you can access Oracle tables fromwithin SQL Server without using a Linked Server. I searched BooksOnline using keywords: linked, remote, and Oracle and did not findanything.A search of the newsgroup archives found only entries related to usingLinked Servers.Is there any such method as claimed? I do not think there is, but Ineed to find some support for my position or else learn something new.Thank you-- Mark D Powell --

There is any tools or products that allow Oracle Users to access SQL 2000 data in realtime? I know how to go in the opposite direction using linked servers, but am not sure on this direction,
Thanks

Hi,
I have been asked to look at optimising a Data Migration Strategy for one of our clients. I am quite new to Data Migration (I'm actually a system designer!).
The migration is from a legacy Oracle 7.16 Db to a SQL Server 2000 environment.
The legacy Db has some large tables - 30 Million+ rows
Table/column Mapping is 1:1
At present we are using DTS to import into the SQL environment.
My question is: Is there any way to leverage the Oracle 7.16 export to speed up the migration process?
Any advice would be appreciated.
Many thanks
Mike

Hi all,
Would anyone know of any references (online or books) that make it easier for experienced Oracle people to Learn SQL Server. The type of things I'd like to know for example are
The environment for SQL server on a PC (e.g. where the
datafiles are, what's the replacement for tnslistener - general architecture info)
Any significant differences that I'd need to know for creating tables and applications, like what do I use instead of varchar2 for example.
that should get me started.
tia,
Dave

We have a view in a 9205 oracle database. We can query fine
and the decimal precision is there.
When we query this same view from ms sql server we lose the precision
so 115.25 becomes 115.
does anyone know a workaround for this?

I started with SQL Server 2005 Express and created a database. Due to circumstances I needed SS 2000. Uninstalled SS 2005 and installed SS 2000 without incident. I already had SS 2000 Enterprise Manager running with other client databases registered.
When I went to Ent Mgr and tried to register my new SS 2000 instance, I got this error: "A connection could not be established to LOYDSLAPTOP. Reason: SQL Server does not exist or access denied. ConnectionOpen (Connect()). Please verify the server is running and check your SQL Server registration properties (by right-clicking on the LOYDSLAPTOP node) and try again."
I have verified that the following services are both running: MSSQL$SQLSERVER2000 and SQLAgent$SQLSERVER2000.
I am certain that I used the sa user with password originally entered when I installed SS 2000 when I tried to register/connect to the local instance of SS. Plus I also tried to connect using the domain user and password entered when I installed SS and got the same error message.
What am I doing wrong? What do I need to change?
Thanks for any help anyone can offer.

I am currently using MS Access for my site and am ready to move on.
I have obtained (legally) SQL Server 2000 Developer Edition.
Before I install this on my pc to learn this new tool and begin adjustments to my site, I have an important question, If I can phrase it correctly.
1. Will this set up my pc as a SQL server as well as keep the current configurations?
2. I have some projects I would like to keep using MS Access, how would this effect it?
3. I have never created a database using SQL or MySQL, any suggested tutorial links?
Thanks,

Hello,
Well I have completely reformatted my computer and reinstalled windows XP professional with all the updates, xp service pack 2 and .net framework 1.1. Now when I try to install sql server 2000 developer, I get the following message where it asks Local Account or Domain account (I choose Domain):
The logon account cannot be validated for the SQL server service. Verify that the user name and password entered are correct. The logon attempt failed
I am using the administrators account, I didn't have a password on it so I created one but this makes no difference. I also tried creating a new user account with admin rights but this also fails to solve the problem.
Please can someone help me with this,

I uninstalled a previous version of SQL Server 2000 Developer because it had some custom configurations that I didn't want. When I try to re-install, I get an error message saying:
A previous program installation created pending file operations on the installation machine. You must reboot the computer before running setup.
I don't know what other programs affect SQL that I have on my machine. My previous instance only contained two known databases and I have deleted the applications that went with those databases.
I have deleted all known registry settings for SQL Server. I have also stopped the IIS service because I thought it would impact the install.
I rebooted my machine, but I still get the same error when I try to install. I don't know what to do next? Please help!

Hello,
I have two question with respect to the developer edition licensing in SQL Server 2000 and 2005:
Question 1
I wanted to install a developer edition on a Development/Test Server. The server needs to be accessed by our development and Testing team of a team of 20 from their workstations. Is that possible?
Question 2
And if so what are the different licensing options that I can choose from considering that I don't want to install a developer edition of sql server on each workstation? The developer edition will be installed on the Dev/Test Server and the workstations will connect to the server using NT or Standard authentication.
Looking forward for any advice and suggestions.
Thanks!

I upgraded from SQL server 7.0 to 2000 not long ago, I'm running 2000 SP3, WIN 2K. Things worked fine for several weeks after the upgrade but now I'm experiencing Enterprise Manager hang in the case of one database only, when I try to view the design of a VIEW. I can open the VIEW fine and look at the results, EM only hangs when I try to view design.
I have checked another of the active DBs on my server and it is fine, no EM hang.
Any ideas how to troubleshoot this?
thx
**I just realized that I'm running SP3, not SP4 (corrected above). Correct me if I'm wrong but does MS have a fix for this problem in SP4? I seem to recall a similar issue in the KB.
