Oracle MS SQL Migration

Hi
I am following the steps listed here: http://www.oracle.com/technology/obe/hol08/sqldev_migration/mssqlserver/migrate_microsoft_sqlserver_otn.htm
I get to step 5 of Capturing the Microsoft SQL Server Exported Files it does not pickup any of the user tables. I am assuming the reason is that all of the tables in this database start with a three char prefix. For example;
ABC.Table1
ABC.Table2
I know that the script is working because if I select a different database (same server) on that does not have the prefixes it works.
Thanks for the help.

Sorry I don't know what you mean by wrap. I am running the script that can be found here (sorry its a video so can't like directly to it) http://www.oracle.com/technology/obe/hol08/sqldev_migration/mssqlserver/viewlets/sqlserver_capture.html. So I am running this command;
OMWB_OFFLINE_CAPTURE.BAT <user name> <password> <db Name> <host>

Migrating from SQL Server to Oracle - Emulating SQL Server databases

I want to offer Oracle connectivity from an ADO.NET application that was developed for SQL Server. The application accesses multiple databases, each having the same schema but each storing different data that is confidential to the users of each database. I’ve been reading up on Oracle but have not yet found a way to group tables, views, etc. in a way that would emulate the ‘databases’ of SQL Server.
The application currently uses the SQL ‘CREATE DATABASE’ command to generate each database and then populates each with the appropriate tables. However, CREATE DATABASE appears to work differently with Oracle, creating a new instance rather than a new ‘internal database’. I’m wondering if CREATE TABLESPACE would give me the functionality I’m looking for, if it were subsequently possible to refer to a specific table within a specific tablespace.
I guess it comes down to whether it’s possible to access specific groups of tables, views, etc. within Oracle (e.g. Groups A, B and C, each having relational tables T1, T2 and T3, and be able to access and update data within any specific table, say, B-T2), while also being able to limit access to any of the Groups.
Would ODP.Net offer advantages over the System.Data.OracleClient for this architectural problem?
Any thoughts on how best to proceed would be most welcome. Thanks in advance for any ideas you might have.

Sorry for the delay closing-out this thread but I work from a rural location and we lost our internet service for the two-weeks prior to the holidays. Now back on-line so let's wrap-up.
Oracle and SQLServer are now both being accessed from my ADO.Net application, so a big thanks to all who've helped me with this first use of the forum. Hopefully these final comments might help someone else in turn...
In migrating from SQLServer to Oracle I initially found it hard to stop thinking about accessing multiple databases on a single dataserver and start thinking more about a single instance of a database that supports muliple users, any one of which can be assigned the same schema. While I had used the SQL CREATE command to produce miltiple databases within SQLServer, it serves a completely different purpose for Oracle, creating an entirely new instance that I did not require.
Other differences that I ran in to included Oracle utilizing 'sequences' to autoincrement identities, whereas SQLServer lets you specify the identify while creating a table (here SQLServer may simplify declaration but Oracle's approach may be more powerful, e.g. if the same identity applies across multiple tables). Also ADO.NET command parameters use an '@' prefix in SQLServer but ':' for Oracle. But by-and-large few changes were required to my SQL to get up and running with Oracle (I found the 'Oracle Database SQL Reference' useful but no substitute for logging into Oracle and just trying each string in the 'SQL Commands' area).
Clearly I'm no database expert and I've barely scratched the surface with Oracle, but after logging in through the 'Database Home Page' I've found Oracle to offer a very 'clean' and logical interface that made it easy to move around the application and get a 'feel' for its organization and what it can do before digging furhter into the documentation. The 'Object Browser' is also a great way to quickly view and edit your various tables, views, sequences, triggers, etc., and ditto your data. In short, I think I'm going to like Oracle.
Thanks again and bye for now.

Migration from Access to Oracle through SQL developer

Hi,
I want to migrate an mdb file which contains a set of tables to oracle. During this process, i have created schema and all the tables in Oracle using DDL scripts. I would like to transfer only the data to Oracle from access through SQL developer. How can I do that?
Regards,
Meena

Hi Meena,
You mention that you have created the schema and tables in Oracle using DDL scripts. Did you use the Oracle SQL Developer Migration Workbench, creating a Migration Repository, to carry out this process? I see from your other postings that you are experiencing issues using the Exporter tool, which would lead me to believe that you haven't used the Migration Workbench to migrate your database. Obviously you will need to resolve your Exporter issues before you can proceed to the next phase of the migration process. I will aim to assist you with those issues on the seperate thread - ShowSplashScreen("_OracleSplashScreen",3) error The XML file generated by the Exporter tool forms the basis of your MS Access migration.
In order to migrate your data from MS Access to Oracle using the Migrate Data option in Oracle SQL Developer, you will need to have access to the Migration Repository used for the migration of the MS Access database. The information contained in the Converted Model, in the Migration Repository, is used during the data migration process. The data migration requires the following connections:
1. a source database connection i.e. a database connection to the MS Access MDB file
2. a target database connection i.e. a database connection to the migration Oracle schema
3. a Converted Model connection
For further information on the creation of a Migration Repository, and the migration process, please refer to the accompanying documentation available via the online Help within Oracle SQL Developer, and also from OTN - http://download.oracle.com/docs/cd/E10405_01/doc/nav/portal_booklist.htm.
I hope this helps.

Oracle to MS SQL Migration Price Prediction

We want to calculate approximate man-month for migrating from Oracle 11g to MS SQL 2012. I have read the steps of migration. Are there any white papers about migration issues, difficulties. We are also using Hibernate in ORM layer. How can we predict migration
cost according to table size or relation count, HQL or native SQL query number or other criteria?

Hi ozgurba,
According to your description, you could download and use the free tool
Microsoft SQL Server Migration Assistant v6.0 for Oracle(SSMA) to migrate Oracle database to SQL Server 2012. About migration issues using SSMA, please pay attention to the points below. For more information about migration issues, please download and check
this
white paper.
1.The account that is used to connect to the Oracle database must have at least CONNECT permissions. This enables SSMA to obtain metadata from schemas owned by the connecting user. To obtain metadata for objects in other schemas and then convert objects
in those schemas, the account must have the following permissions: CREATE ANY PROCEDURE, EXECUTE ANY PROCEDURE, SELECT ANY TABLE, SELECT ANY SEQUENCE, CREATE ANY TYPE, CREATE ANY TRIGGER, SELECT ANY DICTIONARY.
2.The account that is used to connect to SQL Server requires different permissions depending on the actions that the account performs as the following:
To convert Oracle objects to Transact-SQL syntax, to update metadata from SQL Server, or to save converted syntax to scripts, the account must have permission to log on to the instance of SQL Server.
To load database objects into SQL Server, the account must be a member of the sysadmin server role. This is required to install CLR assemblies.
To migrate data to SQL Server, the account must be a member of the sysadmin server role. This is required to run the SQL Server Agent data migration packages.
To run the code that is generated by SSMA, the account must have Execute permissions for all user-defined functions in the ssma_oracle schema of the target database. These functions provide equivalent functionality of Oracle system functions, and are used
by converted objects.
If the account that is used to connect to SQL Server is to perform all migration tasks, the account must be a member of the sysadmin server role.
If the engine being used is Server Side Data Migration Engine, then, before you can migrate data, you must install the SSMA for Oracle Extension Pack and the Oracle providers on the computer that is running SSMA. The SQL Server Agent service must also be
running. And when SQL Express edition is used as the target database, only client side data migration is allowed and server side data migration is not supported.
3.Not all Oracle database objects have direct equivalents in SQL Server. In many cases, SSMA creates additional objects to provide the proper emulation. For example, an Oracle view could be converted to an SQL Server view. But the only exception is the materialized
view, which becomes an ordinary table.
4.Oracle DML triggers are converted to SQL Server triggers, but because the trigger functionality is different, the number of triggers and their types can be changed. Most common Oracle trigger is a row-level trigger (FOR EACH ROW). SQL Server supports only
statement-level triggers. In a row-level trigger, Oracle uses an :OLD alias to refer to column values that existed before the statement executes. SQL Server uses two pseudotables, inserted and deleted. If you are converting tables with UPDATE triggers, we
recommend setting the Generate ROWID column option to Yes or Add ROWID column for tables with triggers in the SSMA project settings. To emulate row-level triggers, SSMA processes each row in a cursor loop.
5.Some Oracle object categories, such as packages, do not have direct SQL Server equivalents. SSMA converts each packaged procedure or function into separate target subroutines and applies rules for stand-alone procedures or functions.
6.Unlike Oracle, Microsoft SQL Server 2012 supports neither records nor collections. When you migrate from Oracle to SQL Server 2012, therefore, you must apply substantial transformations to the PL/SQL code.
7.SQL Server 2012 does not support autonomous transactions. The only way to isolate a Transact-SQL block from a transaction context is to open a new connection. To convert a procedure, function, or trigger with an AUTONOMOUS_TRANSACTION flag, you split it
into two objects. The first object is a stored procedure containing the body of the converted object. The second object is a wrapper that opens a new connection where it invokes the first object.
In addition, regarding migration price prediction, please ask for the help from relevant department of your company, since this forum is related to the technical support for SQL Server.

Migration Oracle to SQL Server

Hello folks
I´m planning database migrate from oracle to sql server 2005
I have windows 2003 server 32bits, R3 4.72 and Oracle 9i, i want to change just database software (oracle to sql)
Do you have any idea to do this?
I was thinking use the installation master to do the export database and later instal sql server and import the database via installation master too but im not sure if a will get errors or something like that
Thanks

Heterogeneous migrations must be done by a certified migration consultant, otherwise you will loose support for the migration itself and for the target system. See http://service.sap.com/osdbmigration
I was thinking use the installation master to do the export database and later instal sql server and import the database via installation master too but im not sure if a will get errors or something like that
Basically you're right - but there are a few things for source and target system to consider; using just the tools and kernels from the installation DVD is likely to fail since they are too old and must be replaced during the migration with newer tools.
BTW: there's a separate forum for migrations:

Migrating data from oracle to sql server

I have two databases(Oracle and Sql Server) in my company.
I want to migrate some data on daily basis from Oracle to Sql Server.
what are the best methodologies used to perform this task?
Can we schedule this task on daily basis?
please help me guys

Salma,
First and foremost, you need to understand that there are architectural difference between Oracle and SQL Server (with the major one being the difference between Oracle's PL/SQL and Microsoft's Transact-SQL) thus, it will not be an easy task to migrate data from Oracle Database to SQL Server. As far as the use of tools is concerned, you can utilize the following tools (third party tools not recommended) to achieve this:
Microsoft SQL Server Migration Assistant (Oracle to SQL)
http://www.microsoft.com/sqlserver/2005/en/us/migration-oracle.aspx
Oracle SQL Developer Migration Workbench (SQL to Oracle)
http://www.oracle.com/technology/tech/migration//workbench/index_sqldev_omwb.html
But before proceeding with anything, I would recommend you to read through the following post as it lists down the primary compatibility resources and migration guidelines:

Hope this helps.

Data filter when migrating Oracle to SQL

How can I use a data filter (via t-sql or ??) when using SSMA to migrate data from Oracle to SQL Server ?

Hi sqlworker,
SQL Server Migration Assistant for Oracle are designed to migrate data from Oracle to SQL Server, we can convert and synchronize the schema of database, the particular category of the schema, and the attributes of objects. However, we can only use data filter
to help you retrieve from a database table by using the WHERE clause to specify search conditions in SQL. According to your description, we need to verify if you just want to migrate some specific data from Oracle to SQL Server, or just use data filter in
SQL Server after migration. You can post more information for analysis.
For more information, you can review the following article.

SSMA 6.0 Oracle to SQL Server 2012 Migration

Hi SSMA Team,
We were migrating data from Oracle(Oracle 10.2.0.5.0)
to SQL server 2012 via SSMA 6.0 and during the migration experiencing below error
“ORA-03106: fatal two-task communication protocol error”
We are using SSMA on Windows server 2008 R2 standard 64 Bit server, also SSMA is configured to use basic Oracle provider.
Would you also please let us know what Oracle Client provider is used in SSMA 6.0 to migrate the data, additionally can you please confirm that the driver used for connectivity is " System.Data.OracleClient.OracleConnection"?
We have 891 tables to migrate the data from Oracle to SQL server. Out of 891 table we are getting random failures ranging from 3- 9 tables(Failed tables).
We are getting this error in between the data migration of all tables, as we have done the settings to continue the data migration in case of failures. It continues to migrate data for rest of tables. We are using SSMA console
V 6.0 to migrate the data.
I can assure you that this is not the permission issue at all (since the migration go successful for other tables and failed only for 3-10 random tables only). Following is the Variable file details we using.
<variable-group name="OracleConnection">
    <variable name="$OracleHostName$" value="SourceHostname"/>
    <variable name="$OracleInstance$" value="DP"/>
    <variable name="$OraclePort$" value="1521"/>

    <variable name="$SQLServerUsrID$" value=""/>
    <variable name="$SQLServerPwd$"    value=""/>

Migration of Database from Oracle to SQL Server in Business Objects XI 3.1

Hi,
Currently, We are working on Business Objects XI 3.1 and Database is Oracle 11g. And now we have the requirement to migrate from Oracle 11g to SQL Server 2008 R2.
I would like to know what are the key points to be considered in business objects XI 3.1 when the database is migrated from oracle to SQL server.
If anyone can share the Impact analysis document for Business Objects, it would be great.
Thanks,
Lavanyaa TP

If you use business objects tools for such migration , the impact should be minimal.
CMSDBCopy mechanism from CCM should work fine for this purpose.

How can i migrate Power Builder 8.0 Function into oracle PL/SQL

Hi Oracle Experts...
How can i migrate Power Builder 8.0 Function into oracle PL/SQL.. I had migrate some of the coding from PB to PL/SQL. But i don't know how can i convert PB structure(here structure is a data type) into oracle PL/SQL.

What are you going to return the structure to? What I would normally use here if the code was going to be used by other PL/SQL would be a PL/SQL object type.
However, if PowerBuilder is still in the equation (you're moving the logic to PL/SQL but keeping PowerBuilder for the GUI ), then you'll have to return something else, because PowerBuilder doesn't understand PL/SQL object types. Perhaps passing a REF CURSOR as a OUT argument and populating it from the procedure. PowerBuilder could then retrieve the result of the procedure using a stored procedure based DataWindow.

Error while converting schema from oracle to SQL server

Hello,
I am getting following error while converting schema from oracle to SQL server using SSMA.
I get Errors 1-3 while migrating procedures and error 4 while migrating a table.
1- O2SS0050: Conversion of identifier 'SYSDATE' is not supported.
2- O2SS0050: Conversion of identifier 'to_date(VARCHAR2, CHAR)' is not supported.
3- O2SS0050: Conversion of identifier 'regexp_replace(VARCHAR2, CHAR)' is not supported.
4- O2SS0486: <Primary key name> constraint is disabled in Oracle and cannot be converted because SQL Server does not support disabling of primary or unique constraint.
Please suggest.
Thanks.

The exact statement in oracle side which causing this error (O2SS0050:
Conversion of identifier 'to_date(VARCHAR2, CHAR)' is not supported.) is below:
dStartDate:= to_date(sStartDate,'MON-YYYY');
Statement causing error O2SS0050:
Conversion of identifier 'regexp_replace(VARCHAR2, CHAR)' is not supported is below.
nCount2:= length(regexp_replace(sDataRow,'[^,]'));
So there is no statement which is using to_date(VARCHAR2,
CHAR) and regexp_replace(VARCHAR2, CHAR) in as such. 'MON-YYYY' and '[^,]'
are CHAR values hence SSMA is unable to convert it from varchar2 to char.
Regarding SYSDATE issue, you mean to put below code in target(SQL) side in SSMA ?
dDate date := sysdate;
Thanks.

Question about transfer between oracle and sql server

Could i program to transfer lots of data between Oracle and SQL Server quickly?
I have tried make two connection between two databases, but it took me lots of time to transfer data.
How could I do it?
Thanks

Hi,
If you need to move data fast, then use the Oracle Migration Workbench to Generate SQL Server BCP data extraction scripts and Oracle SQL Loader files.
This is the fastest way to migrate the data.
In the Oracle Model UI tab of the Oracle Migration Workbench, right mouse click on the tables folder. there is a menu option to 'Generate SQL Loader ...' scripts. This will help you migrate your data efficiently.

John

Differences between being an Oracle and SQL DBA?

Sorry to post this here, but I need so insight and don't know any Oracle DBA's. As posted here before, Ive been a MSSQL DBA for about 6 years and want to broaden my skill set. One of my ideas is to learn Oracle. For the record, I do realize that my teaching myself wont open up hundreds or Oracle DBA jobs, but Im hoping to land a "mostly SQL with a little Oracle" gig somewhere. Ive successfully installed Oracle on Linux, and now need to make a decision on if to proceed or not. Any insights from people that have worked with both platforms would be especially helpful, but all thoughts are definately welcomed. So now my questions:
1. Why are Oracle DBA's paid more than SQL DBA's? It must be something skill specific? What is it?
2. Will this trend likely continue as newer versions of Oracle are released that are easier to manage?
3. With that extra cash, is there typically more hours involved? I dont mind working a bit extra if needed, but I do have little ones that I'd like to watch grow up.
4. Are there typically differences in the job responsibilities between Oracle and SQL DBA's? The changing trend these days is to include DTS/ Analysis Services/ Reporting Services all under the DBA umbrella. Do Oracle DBA's typically have the same type of stuff?
5. If I do continue down this path, it would probably be far easier for me to learn on Windows than *nix. Is this a valid thing to do, or should I not bother? I've been told that it's still worth while, but have real reservations about needing to tell an interviewer "I've only used it on Windows".
I realize this is all subject to personal experiences and feelings, but don't know how else to figure this stuff out without asking.
TIA, ChrisR

By SQL DBA, I assume you mean SQL Server DBA. SQL is 'Structure Query Language' and is not a specific product, no matter how much the Microsoft community might wish to usurp the term. <g>
There are mauy reasons for this, including the Oracle vs Microsoft mindset that has been nurtured over the years. For many managers, 'Oracle is solid, reliable and expensive' whereas 'Microsoft SQL Server is cheap, not necessarily as reliable, but good enough'.
Whether true or not is irrelevant, these are direct quotes from some of my customers.
My remaining answers are based on my personal experience, and may only be valid in my area. (Yes, things are VERY regional.)

1. Why are Oracle DBA's paid more than SQL DBA's? It
must be something skill specific? What is it? Often, an Oracle DBA is a trained DBA. SQL Server DBAs seem to be decent developers who are [or have been stuck] doing DBA work.
I find that SQL Server DBAs who are truly capable of handling all of {backup, recovery, troubleshooting, security, development, disaster recovery, audit, locking, configuration, RAID and disk, upgrade, migration and porting (to name a few)} competently are generally paid comparable to Oracle DBAs.
However, I also find there are extremely few true SQL Server DBAs.

2. Will this trend likely continue as newer versions
of Oracle are released that are easier to manage?Yes.
Although Oracle administration is easier, DBAs are now expected to handle more instances, and adminstrator across more servers, and are expected to be competent in more of the feature capabilities.
There is NO reduction in the amount of work. The 'easier to manage' stuff simply means being more efficient.

3. With that extra cash, is there typically more
hours involved? I dont mind working a bit extra if
needed, but I do have little ones that I'd like to
watch grow up.
A blatant observation: Oracle tends to be used in more mission critical environments, and SQL Server in department support environments. Mission critical tends to be watched closer, and require 'fast aqnd competent' response. Pager duty seems to be more prevelant in Oracle positions - department server crashes can be handled by a reboot in the morning.
4. Are there typically differences in the job
responsibilities between Oracle and SQL DBA's? The
changing trend these days is to include DTS/ Analysis
Services/ Reporting Services all under the DBA
umbrella. Do Oracle DBA's typically have the same
type of stuff?Many SQL Server 'DBAs' I know personally are 'super developers' but not really DBAs.
Observation: DBAs are often very 'repeatable' detail oriented, whereas developers are 'get it done' oriented. Very different mentailties, both very important.

Is this a valid thing to do, or should I not bother?
I've been told that it's still worth while, but have
real reservations about needing to tell an
interviewer "I've only used it on Windows". Oracle is quite operating system independant. Pick your poison.
SQL Server is quite operating system dependant. Some else picks your poison.
There is no shame in saying to an interviewer that you have a strong competence in Oracle but only experience in Windows. A good potential employer will often provide appropriate additional training to a suitable, honest, candidate.

I strongly encourage you to contact locals rather than ask in these forums. Check whether there is an Oracle User Group close to you, and meet and chat with the members. Ditto for SQL Server. (You can find out by contacting respective sales reps.)
The above is NOT a dismissal of SQL Server capabiltites or SQL Server DBAs. (Some close friends are extremely competent with SQL Server.) It is just a set of personal observations.
