OMWB Sybase Version ? to Oracle Version ? & Migration Verifer

The documentation states that OMWB will migrate schemas and data from Sybase 11 or 12 to Oracle. My question is what versions are covered? There is a considerable difference between the various version of Sybase 12. My extact migration plan would be move structures and data from a Sybase 12.5.2 server on Solaris 8 to an Oracle 10g R2 server on Solaris 10. I was planning to follow up the migration with the Migration Verifier, but I do not know if it can cover these versions.

12.5 is supported by the Oracle Migration Workbench so you should be fine with this.

Problems with Sybase 12 to Oracle 10g migration

Hi,
I'm using SQL Developer to test a migration between Sybase and Oracle and it doesn't work (both online and offline)
I've create a dedicated user account and connection, with the roles and privileges required (as seen in http://download.oracle.com/docs/cd/B32485_01/doc/appdev.110/b31695/migration.htm#i1005739)
I've created the migration repository without any problems (using the above user account).
QUICK MIGRATION
- select the source Sybase connection: OK
- select the target Oracle connection: OK
- select the referential: OK
- verify privileges before migration: OK
- migrate tables only and click Next
## window closes and nothing happens ## - nothing on Captured Model pane
CAPTURE SOURCE SYBASE DATABASE
- right click on the Sybase connection in the Connections pane
- choose Capture Sybase
## window closes and nothing happens ## - nothing on Captured Model pane
OFFLINE CAPTURE
- create database capture scripts: OK
- launch the database scripts (SYB12_OFFLINE_CAPTURE.BAT): OK
- load database capture script output (sybase12.ocp)
## window closes and nothing happens ## - nothing on Captured Model pane
I can't find any relevant logs or trace from the application.
I even tried to use the capture file sybasemigration.zip from the "Migrating a Sybase Database to Oracle Database 11g" web page (http://www.oracle.com/technology/obe/hol08/sqldev_migration/sybase/migrate_sybase_otn.htm), but the result was the same.
Does anyone encountered the same problems? Does someone knows where are the logs (if any)?
Thanks in advance.
Regards,
Pedro

Hi Pedro,
What version of SQL Developer are you using?
Can you browse your Sybase connection in SQL Developer, to see its tables for example?
If not, then you may need to point SQL Developer to your JTDS 1.2 driver again.
Are you capturing a non system database ? SQL Developer wont migration master or tempdb ...
Can you try running SQL Developer from the command line and watch the command line for any errors during the capture.

Sybase TEXT to Oracle CLOB migration

Hi All,
We are doing the migration from Sybase to Oracle 10g.
Migration steps include..
1. Creation of Oracle staging area similar structure as Sybase database.
2. Extract the data through BCP
3. Import to oracle by Sqlldr (sql loader)
But we have problem in migrating the SYBASE TEXT column into ORACLE CLOB, as Sqlldr ( sql loader) can load clob column only 500 bytes, unless we are not using LOBFILE clause.
To use LOBFILE clause, we have to create "Secondary Data file " , But BCP have limitation. It is not supporting custom query to generate CLOB column data file.
Help me in resolving this issue.

It is not supporting custom query to generate CLOB column data file.As I understand it, the core issue is that SQL*Loader wants you to point it to the file containing the CLOB to load. While BCP puts the TEXT/CLOB inline in what is essentially a BCP produced CSV file.
Now this is a problem. As the CLOB can contain all kinds of formatting, including end-of-CSV-row characters, special characters and so on, it can easily render the format of that CSV file useless.
SQL*Loader expects a CSV file where the CLOB column contains a filename to load - and where that file contains the contents of the CLOB. With this approach there is no issues dealing with complex file formatting rules in trying to load the CLOB as a part of a CSV file.
So extract the data in this format - do not restrict yourself to the limitations of BCP. That TEXT column must have a PK column (or two). Write a script that extract the TEXT into a default directory, creating a file that is uniquely identified by the PK.
Extract the rest of the table's content (using BCP for example) into CSV format. Now you have the data in the two parts (CSV file and separate CLOB files) that SQL*Loader expects. Create the appropriate control file and load the data. This should not be that complex to do.

Migration from sybase 11 to Oracle 9i

Hi,
I have to migrate all db objects (tables structures,table data,triggers,sp) from Sybase 11 to Oracle 9i
There are currently two free tools -
Migration workbench (http://www.oracle.com/technology/tech/migration/workbench/index.html )
and
SQL Developer( http://www.oracle.com/technology/tech/migration//workbench/index_sqldev_omwb.html )
for this purpose.
SQL developer has a provision to convert scripts which I can use for SPs and scripts one @ a time.
Problem is migrating table structures along with data.
from SQL developer I can't connect to sybase thou I provide all the details and from workbench in the online mode I need the sa login which is not possible as the database is live and @ client side.
SQL Loader can be used but will require to make CSV files from each sybase table and hence is time consuming.

Hi,
Migration Workbench is not available for Sybase database.
As you can see on this website:
http://www.oracle.com/technology/tech/migration/workbench/files/mig_rel10104.html
Only Informix and DB2 database are supoprted now with this product.
With SQL Developer, we only support last versions of Sybase : V12 and V15.
As you don't have any remote access to your client database and no SA login , the best way would be :
==>to get and export from Sybase 11.
==>install a V12 somewhere (on your site , you can download the Sybase V15 )and import the Sybase database
Then SQL developer can migrate quickly your database without any problem.
I hope it helps you.

Migration from Sybase 11 to Oracle 8i

I am trying to migrate a Sybase DB to Oracle 8i. The platform of Sybase system is VMS and Oracle is UNIX. Can I use workbench to migrate between two different platform?
If not, is it the only way to export sybase to a flat file and then load to Oracle using SQL loader?
Thanks

SQL Developer 3.1 not migrating Sybase Users to Oracle 11g R2

I have tried both online and offline capture and the Sybase users are not being captured (Tables, Views, Procedures Worked). I searched this forum and saw another post about this issue but the Oracle representative never came back with a final finding/answer. We have 1000+ users to migrate so all help is appreciated.

Hello.
sorry for the delay (if you need quicker response I suggest that you open a Service Request in My Oracle Support).
In your first post you said that you tried online and offline migration. So for an offline migration you have created the scripts using the Create Database Capture Scripts menu button. Then you have run that scripts against Sybase. Has there been created a file SYB15_SYSUSERS.dat (or SYB12_SYSUSERS.dat if your Sybase version is 12)? If that file has been created, does it contain anything or is it empty?

Migrating Sybase code to Oracle 11g

Hi All,
We have to migrate Sybase code to Oracle 11g.
When we are doing a SELECT .. INTO in Sybase , even if the query is returning more than 1 row , sybase selects 1 of the rows and populates the variables.
But while migrating this code to oracle, we are getting TOO_MANY_ROWS Exception.
We need to migrate the code from SYBASE to ORACLE without disturbing the logic.
Can someone please tell me the logic applied by SYBASE to pick up the record?
And if someone has faced this issue, then what can be done to resolve this.
Regards,
Riddhisha Khamesra

The result 3 is the last entered record (not the amount of records..).
So the first approach to write a dummy procedure that will select all records in Oracle like:
CREATE OR REPLACE PROCEDURE last_record
v_arg1 OUT NUMBER
AS
BEGIN
SELECT col1
INTO v_arg1
FROM tt_tmp ;
END;
and hopefully returns only the last record will fail with:
SQL> variable outvar number
SQL> exec last_record (:outvar)
BEGIN last_record (:outvar); END;
ERROR at line 1:
ORA-01422: exact fetch returns more than requested number of rows
ORA-06512: at "SYSTEM.LAST_RECORD", line 9
ORA-06512: at line 1
One possible approach to get the last (and only the last) record that was entered into the table is to use rownum:
The select might look like "select col1 from (select col1, rownum from tt_tmp order by rownum desc) where rownum=1;"
So the procedure can be coded as:
CREATE OR REPLACE PROCEDURE last_record
v_arg1 OUT NUMBER
AS
BEGIN
SELECT col1
INTO v_arg1
from (select col1, rownum from tt_tmp order by rownum desc) where rownum=1;
END;
Now calling it in SQL*Plus:
SQL> variable outvar number
SQL> exec last_record (:outvar)
PL/SQL procedure successfully completed.
SQL> print :outvar
OUTVAR
7
The value 7 is the last record I've inserted into my tt_tmp table:
SQL> select * from tt_tmp;
COL1 COL2
1 1
2 2
8 8
7 7

Migrating table from Sybase 12 to Oracle 10g

Hi ,
We have a situation where we have to migrate multiple Sybase databases to Oracle10g . These multiple database have same set of tables but different data in these tables on each sybase database ( data differ, based on location or region wise but same table name and structure). We want to migrate all these sybase database to Oracle 10g and in single database, which involves inserting data from multiple tables ( though they exist on different database in sybase) into single Oracle table.
for example if we have a table 'TESTK' that exist on five different sybase database but with different region wise data. I want to bring data from these five tables( Five as they exist in five differet sybase databases) and insert them into a single oracle table 'TESTK' .
Have anybody ever face such scenerio , what are all possible approch please suggest. Once data is inserted into oracle table i need to partitioned this oracle table as well.

It is not quite clear whether you have multiple tables (referencing each other) in multiple sybase databases or either one table or several non connected tables in multiple sybase databases.
In the first case of course your task is harder because you need to keep references and most probably you cannot blindly copy data from db 1, db 2 and unite them because they can have the same id's coming from different sources.
In the second case your task of course is much easier you can simply load all your data in Oracle tables either using some interim tables (if you need to filter out duplicates) or load data straight into target tables if you are sure you haven't duplicates.
Also another question in case 1 is whether intersection of your data is 0 rows i.e. all data are completely different in each source db or not.
So I'm sure you can find tools for blindly moving data from sybase to Oracle, although if you need to do some more complex filtering, computation or whatever you most probably need to write it yourself.
I'v done a few data conversion projects from one schema to another and as the requirements were quite complex the only possibility for us was to initiate a separate data conversion project and create conversion software (pl/sql packages manually).
You can find an overview of our approach in my article "Data migration from old to new application: an experience" here http://www.gplivna.eu/papers/legacy_app_migration.htm

OMWB schema prefix (MS SQL Server to Oracle database migration)

I made automatical migration + some manual changes (pipelined functions) to migrate MS SQL 2000 database to Oracle 9i. Still one issue remains which requires lot of manual conversion : Names of the tables in views after automatic migration doesn't contain schema prefix and it doesn't compile on destination database.
My question is: Is there any way to add schema prefix to table names in views automatically during migration process ?

Two things here.
The omwb will login to Oracle and create the views in the schema where they will be stored, hence not needing the schema appended.
If the views are on other schemas than the one being installed into, then yes, there may be some manual edits to do to the table names in the views. This is not configurable today.

Sybase 4.x to ORACLE 7 migration

I am trying to use your Sybase 4.x to ORACLE 7 migration
toolkit, and found out that one file is missing under
/convkit/sybase/chkdupnms/ after I unzip the downloaded
sybase4x_tar.z. The missing file is DUPNMS_RPT. On your
conversion guide, it said that this file should be there. Did I
missing something? Is it necessary to have this file? If it's
so, how do I obtain this file? I'd appreciate your reply ASAP.
Thanks.

Hi Ann,
I think this file checks for duplicate names. You may be able to
work without it.
You may have to perform some manual steps to overcome name
collisions if they occur, but these are usually straightfoward.

How to use a Sybase table in Oracle SQL statement?

How to use a Sybase table in Oracle SQL statement?
Sybase version : 11.9.2.4
Oracle version : 10.2.05
Thanks.

Sybase version : 11.9.2.4

Thanks.Any Oracle client connected to the Oracle database can access Sybase data through the Database Gateway for Sybase (it requires an additional license) or the Database gateway for ODBC (it's free).
The Oracle client and the Oracle database can reside on different machines. The gateway accepts connections only from the Oracle database.
A connection to the gateway is established through a database link when it is first used in an Oracle session. In this context, a connection refers to the connection between the Oracle database and the gateway. The connection remains established until the Oracle session ends. Another session or user can access the same database link and get a distinct connection to the gateway and Sybase database.
Database links are active for the duration of a gateway session. If you want to close a database link during a session, you can do so with the ALTER SESSION statement.
To access the Sybase server, you must create a database link. A public database link is the most common of database links.
SQL> CREATE PUBLIC DATABASE LINK dblink CONNECT TO
2 "user" IDENTIFIED BY "password" USING 'tns_name_entry';
--dblink is the complete database link name.
--tns_name_entry specifies the Oracle Net connect descriptor specified in the tnsnames.ora file that identifies the gatewayAfter the database link is created you can verify the connection to the Sybase database, as follows:
SQL> SELECT * FROM DUAL@dblink;

Oracle Database Migration Assistant for Unicode (DMU) is now available!

Oracle Database Migration Assistant for Unicode (DMU) is a next-generation GUI migration tool to help you migrate your databases to the Unicode character set. It is free for customers with database support contracts. The DMU is built on the same GUI platform as SQL Developer and JDeveloper. It uses dedicated RDBMS functionality to scan and convert a database to AL32UTF8 (or to the deprecated UTF8, if needed for some reasons). For existing AL32UTF8 and UTF8 databases, it provides a validation mode to check if data is really encoded in UTF-8. Learn more about the tool on its OTN pages.
There is a new Database Migration Assistant for Unicode. We encourage you to post all questions related to the tool and to the database character set migration process in general to that forum.
Thanks,

HI there!
7.6.03 ? Why do you use outdated software for your migration.
At least use 7.6.06 or 7.7.07 !
About the performance topic - well, you've to figure out what the database is waiting for.
Activate time measurement, activate the DBanalyzer with a short snapshot interval (say 120 or 60 seconds) and check what warnings you get.
Also you should use the parameter check to make sure that you don't run into any setup-induced bottlenecks.
Apart from these very basic prerequisites for the analysis of this issue, you may want to check
SAP Note 1464560 FAQ: R3load on MaxDB
Maybe you can use some of the performance features available in the current R3load versions.
regards,
Lars
p.s.
open a support message if you're not able to do the performance analysis yourself.

Sybase12.5 to Oracle 9i Migration:Error while capturing thru offline

Hi,
While migrating data from Sybase 12.5 to Oracle 9i we are getting the following error.
java.sql.SQLException: ORA-01401: inserted value too large for column
Exception :Sybase12DisconnSourceModelLoad.loadSourceModel(): oracle.mtg.migration.MigrationStopException: java.lang.NumberFormatException: For input string: "« ? » ±"
Log shows that it is failed while loading data from sybase12_syssptvalues.dat file. Please advise what could be causing this error?
Regards,
Prasad Jaldu

Prasad,
The data in the column contains the column separator we
are using, alter the data, load and alter the data back,
or change the delimiter and re run the offline capture
scripts.
see the user guide Omwb/docs/usersguide/trouble.htm#sthref455
or look up delimiters in the index of the user guide
This should solve your NumberFormatException issue.
