Moving from MS SQL 7 to Oracle 8i

We are thinking about moving one of our client/server applications from MS SQL 7.0 to Oracle 8i. We know that we will have to change some of the datatypes in the database. But will there have to be a major rewrite of the backend code (stored procedures, triggers, views, etc...)? Does Oracle 8i support SQL or just PL-SQL and JAVA?

Thank you all, at the end, i have fixed the problem. It seems root cause of the problem is my regional settings.
I have completed to transfer my Sql schema to Oracle with errors. Migration Wizard gives errors in the stage of creating relations. It is something like that,
Failed to create foreign key: ORA-02298 Cannot validate - Parent keys cannot find
I have also tried to migrate my sql data but when the wizard finishes running, a large amount of my data is also lost.
Do you have any suggestions?
Thank you.

This needs the user to have access on all_objects view and it will limit the result upto the numbers of objects returned by the all_objects view.

OLAP data from MS SQL to Oracle

Hi,
I am currently using Microsoft SQL server 2000 as our datawarehouse with Analytic services(OLAP data).
We are thinking of migrating to Oracle 10g. By using Migration Workbench, will it migrate my 3 dimensional data(OLAP) from MS SQL to Oracle (OLAP) ?
Thank you.
Best Regards,
Ian Ho

This could happen if you are using improper LKM
So depending on your source and staging database you choose the corresponding LKM
for example:
If you are using MS SQL Server as your source and Oracle database as the staging database, then you should be using lKM SQL to Oracle

Insert Data from Oracle to MS-SQL and back from MS-SQL to Oracle !

Dear Gurus,
Good day,
I have Oracle db 10.1.0.2 on Sun Solaris 9 and want it to communicate online with an MS-SQL server DB on a windows machine.
Oracle states that i can use the TG4MSQL ( Transparent Gateway for MS-SQL ).
The issue here that this TG4MSQL needs to be installed on a db on WINDOWS then make a DB link from this db to MS-SQL as well as to the original oracle db because TG4MSQL is not available on UNIX ( only in 11g ) !
Is there any way to do this 2-way insert from/to MS-QL & Oracle without creating a new dummy DB for TG4MSQL?
Is there any other ways or methods?
Please advise,
Appreciate your help.
Cheers,
Firas

I think you must have mis-read or mis-understood about the Transparent Gateway. I've not worked with the one for MSSQL but have for DB2.
The OTG installs on the server with the 'foreign' (non-Oracle) database. It simply acts as a client to that database, presenting an Oracle interface on the other side - somewhat analogous to ODBC presenting a common interface for connections to various db or db-like products.
As such, it only makes sense that the OTG for MSSQL would only be available for Windows ... Windows is the only platform that MSSQL runs on.
When I was using the OTG for DB2, we simply installed the OTG on the Z/OS system (IBM mainframe) hosting the DB2, then defined a dblink in the Oracle database (that one was running on Windows) to point to it. As far as the Oracle db was concerned, it had no reason to know that the link was pointing to a non-Oracle db.

Migration from MS SQL to Oracle

We have developed our application with VB.net and MS SQL server (that is also loaded with a big number of stored procedures), the application is also using Web services and xml and other technologies.
Currently my issue is, that many of our potential clients demand for Oracle server at the back-end, I need a sound tool to migrate from MS SQL to Oracle

The thing to do is check out the Migration Workbench.

Tools for migrating data (documents) from MS SQL to Oracle

Hi,
Please let me know if there any tools available for migrating documents from one database like MS SQL to Oracle. Currently our documents are stored in MS SQL and we are planning to implement KM for document management with Oracle as the database.
Regards,
Suresh

The old manual style still works - create the scripts for the migration objects, then use search & replace to rename the schema for all affected objects and finally run the SQL script to create them in the Oracle database.

Using sockets with java from PL/SQL in Oracle 8.1.7 DBA

Hey all,
I've been struggling for a couple of weeks now with a problem. I wrote a framework around a toolkit which makes socket connections to another server. I am attempting to use the framework from within a PL/SQL script, which is calling the framework class files which have been loaded into Oracle 8.1.7 database. The problem seems to be if I grant all permissions, or socket permissions for all hosts/ports, or even the ones I know about are being used, I get a hang when trying to connect. The funny thing is, using the toolkit, if I invoke their classes directly within code written from Oracle's code editor, it will work.
I suspect there is
a) Some hidden permission issue
b) A bug in the sockets implementation Oracle is using for their JVM.
Can anyone offer insight to this problem?
Thanks,
Dave Blake

Hello,
I'm trying to investigate the same thing.
I want to make a soap-client with PL/SQL with 8i 8.1.6.0.0
Did you succeed some additional information ??
I tried to run the following example:
http://www.oracle.com/technology/tech/webservices/htdocs/samples/dbwebservice/DBWebServices_PLSQL.html
but it only works with 9i.
With 8i the errors encountered were : XMLTYPE undefined
Perhaps if we find the definition of XMLTYPE and we process it to 8i we'll be able to run the example ??
thank's

How to change Bulk Insert statement from MS SQL to Oracle

Migration from MS SQL to Oracle/DB2

Hi Gurus,
Not sure if I post in the correct thread. But I need advice on migrating our MS SQL database to either Oracle or DB2.
From ABAP point of view, I believe the standard SAP programs and most of our customized programs are compatiable with any database. However, what are the possiblilty that programs are only catered for MS SQL DB and not the rest? Examples like what type of coding?
Need to know from functional side, do we have to do full functional testing on all the modules that we used? If not, any testing from functional side?
Many many thanks in advance.
Regards,
Janet

> Thanks for the info. However the thread you provided seems to be more on Basis side. Actually I am coming more from application side on which functional module areas (SD, FICO, etc....) we have to test and on ABAP side on which customized programs we should look out for to test or redevelop when migrating. Let me know if have any ideas.
There may be impacts - yes. Each database has its own optimizer and strategy, if you have a table or an SQL statement there may be different access paths and optimization routines for every database.
I'd say it's near to impossible to only theoretically find out how a certain application would be impacted - the only way to find that out is to do a test migration and run regression tests on each of your core applications. You may e. g. delete or create a new index or also redesign the whole statement.

Adapt existing QaaWS from MS SQL to Oracle DB

Hey there,
I have searched for an answer on the Web but cannot find one, so perhaps you can help me:
I am adapting an existing Query as a Web Service from an MS SQL Server to an Oracle DB. After entering the default parameter value for the Query, an error message pops up:
"A database error occured. The database error text is: (CS) "DBDriver failed to load : C:\BOE\BusinessObjects\BusinessObjects Enterprise 12.0\win32_x86\dataAccess\connectionServer\dbd_oci.dll (The specified module could not be found.)" . (WIS 10901)"
I checked for this file, but it is there and checked WebIntelligence to connect to the Oracle DB and that works fine.
Do you have any suggestions/ideas?
Thanks you in advance,
Nils May

Hi,
You can try the following:
1. First check the Universe connection and make sure it is connected to right DB. Oracle or SQL Server.
2. Copy the existing QaaWS and again select the Universe which is connected to correct DB.
3. If that doesn't work, create a new QaaWS.
4. If using parameter, specify parameter and verify data.
Hope this helps.

Poor performance after moving from hp to linux, oracle 11.2.0.1 to 11.2.0.3, filesystems to ASM

We moved a database from HP/UX to linux, upgraded oracle from 11.2.0.1 to 11.2.0.3, and from filesystems to ASM. The new server has 32 cores and 500gb of memory. the old server has less than half of that. Queries take twice as long to run on the new server as on the old server. We've tested to eliminate I/O as the issue by creating a local filesystem and creating the database there. The performance was still double over the old database. We also moved the database to a 3rd server, using ASM and 11.2.0.3 of oracle for testing to prove to the systems administrator that it wasn't a database problem. The performance on the 3rd server is incredibly fast. This points to something on the new server. Does anyone have any ideas of what to look at next, keeping in mind that we've tested the heck out of I/O.
Thanks for any assistance.

Well, a few details about your configuration could help:
What does /proc/meminfo on the server show?
How is the storage connected?
What does: "# /sbin/ifconfig -a" show?
Are you using ASMLIB or straight ASM?
Are you using multipath connections to storage? If so, make sure that "/etc/multipath.conf" actually identifies the composite device and not one of the physical paths.
Are there any entries in "/var/log/messages" while running the ASM testing?
I'm sure these questions will stimulate others.

Java running host command - moved from PL/SQL forums

Hi,
I am not familiar with Java setting in Oracle
I have a a stored procedure that call a java program to execute host command like
ssh user1@localhost '/home/user1/someprogram'
if we execute this directly using PuTTY
we can do the following with no problem
su - oracle
ssh user1@localhost '/home/user1/someprogram'
but when we execute the stored procedure,
we have to do
*/usr/bin/ssh* user1@localhost '/home/user1/someprogram'
does anybody where to set the path or environment to make the java know the path correctly.
thanks
ps:. this is happen after we recently upgraded our Oracle from 9.2.0.8 to 11.1.0.6
