OMW supports sybase ASE 15 to Oracle 10g migration?

Hi,
I want to migrate data from Sybase ASE 15 to Oracle 10g. Can i use OMW for this purpose if not then what is the other way of doing it?
Kind regards
Ankit

No, not the current workbench. We will be bringing out support for Sybase 15 in SQL Developer at the next release.
You could try bringing the db down to 12 if that was an option and then migrate from that.

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.

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

Hai,
Could any of you explain me about Oracle 10g Migration Workbench 10.1.0.4.0
product and also about the features and usage of this project.
Thanks in advance.
A.Mohammed Rafi.

Sandeep,
Have you used this user which holds the omwb repository before for a migration? When you connected the first itme, did you get a message, that the repository tables did not exist and would you like to create them?
Are you using the connected or disconnected source model load?

Sybase ASE to Oracle 11g conversion

Hi,
Can anyone please look at the following Sybase ASE to Oracle 11g conversion - the top remarked code is the original Sybase version and the two UPDATE blocks below are hopefully doing the same task... What I need to know is if there is a more simple (less code change) way of doing the same task, either as a single UPDATE or preferably even more similar to the original Sybase code..?
-- /* now apply allocations */
-- update diary_items
-- set id_user = ia.id_user ,
-- tx_icon_user = 'urlcats:/user_grey.gif?method:getAllocationInfo'
-- from diary_items di,
-- item_allocation ia
-- where di.id_diary_item = ia.id_object
-- and ia.id_object_type = 'W'
-- and ia.id_user != 'autocats'
-- OK!
-- ??? Need to check if second UPDATE which is the same as above is required again...
/* now apply notes */
UPDATE diary_items
SET diary_items.tx_icon_user =
( SELECT 'urlcats:/user_grey.gif?method:getAllocationInfo'
FROM item_allocation
WHERE item_allocation.id_object = diary_items.id_diary_item )
WHERE EXISTS
( SELECT item_allocation.id_object
FROM item_allocation
WHERE item_allocation.id_object = diary_items.id_diary_item
AND item_allocation.id_object_type = 'W'
AND item_allocation.id_user != 'autocats' )
UPDATE diary_items
SET diary_items.id_user =
( SELECT item_allocation.id_user
FROM item_allocation
WHERE item_allocation.id_object = diary_items.id_diary_item )
WHERE EXISTS
( SELECT item_allocation.id_object
FROM item_allocation
WHERE item_allocation.id_object = diary_items.id_diary_item
AND item_allocation.id_object_type = 'W'
AND item_allocation.id_user != 'autocats' )
Many thanks!!!

I managed to work it out in the end - here's the solution...
/* now apply allocations */
update diary_items
set ( id_user,
tx_icon_user ) =
( select ia.id_user,
'urlcats:/user_grey.gif?method:getAllocationInfo'
from diary_items di,
item_allocation ia
where di.id_diary_item = ia.id_object
and ia.id_object_type = 'W'
and ia.id_user != 'autocats'
)

Is Oracle Migration Workbench (OMW) support Sybase IQ 12.4.2?

Hi All,
I understand that OMW support migration of Sybase Adaptive Server 11 and 12. But, is it support Sybase IQ 12.4.2? Our envrionment has 2 Sybase Adaptive Server 11.9 and 1 Sybase IQ 12.4.2 that required to migrated to Oracle 9i.
Thanks in Advanced...

Are you migrating off Sybase IQ to Oracle? I have been asked to work on a project where they are considering using Sybase IQ instead of Oracle. They consider Sybase IQ to be faster. I have been reading the literature but it seems to be comparing Oracle without bitmaps to Sybase IQ which has them built in automatically.
Your thoughts? Please advise.

Migrating from Sybase 11 to Oracle 10G : Data not Captured

Hi,
We are working on an interesting customer engagement - one part of the effort is to migrate our Customer's Database. Our Customer is using the Sysbase 11 Database - we are planning to migrate this to Oracle 10G.
We are using the latest Migration Workbench - 10.1.0.4.0. We created a new user in one of our local DB Instances & used this credential to login to the Migration Workbench tool. We have the Source Files for the Sysbase 11Database.
We tried to capture the Source Model - unfortunately, the Tool claims that the Objects have been migrated, while the Source is not captured at all. The Error Log is alos silent about any problems.
We are flummoxed by this error as we have successfuly migrated from Sysbase in the past, but never encountered this error.
Can you guuys please help us out with this ?
Please do let me know if I need to post more information
Thanks,
Sandeep

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.

umesh chandru wrote:

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.

Oracle 10g migration to linux

Hi,
At present we are maintaining a J2EE application running on a UNIX Platform with the following environment configuration:
o Web Server (Apache 2.0.52)
o Application Server (WebLogic Server 9.0)
o Database Server (Oracle 9i)
The current requirement is to upgrade Oracle 9i on UNIX to Oracle 10g on Linux. Will there be any impact on
· Oracle developer applications (Forms/Reports) because of oracle upgrade?
· .net applications accessing oracle because of oracle upgrade?
· Java applications accessing oracle because of oracle upgrade?
And there are plans to use Oracle Warehouse Builder and Oracle Workflow Server. Are there any known issues with respect to the above applications during this migration?
Thanks,

Hi,
Upgrading on the same machine doesn't work well. Installing in a different machine
will work fine.
This can be done for apps also where you will be migrating the config alone.

Nirmal

You should consult with Oracle about this. If nothing else has changed except the database version, why would it be the fault of Java or BEA?
Actually we don't exactly where is problem occured, wheather it's occured in BEA Weblogic or Oracle database
No one else can guess based on the little information you've provided. Better sort that out. Profile both and see where the time is being spent.

View problem in Oracle 10g migration

Hi,
I am involved in Oracle migration from 9 to 10g.
I have a problem with a view that works in Oracle 9 but in Oracle 10g raise the following error:
ORA-01446: cannot select ROWID from, or sample, a view with DISTINCT, GROUP BY etc.
In the view source there is a call to another view and in the last one another call to a view with a group by keyword because I need the max() column value in a table, so I need the group by keyword!!!
Any suggestion/work around to get the max() value without group by???
thanks

Hi,
Yes, MAX (and almost all the other aggregate functions) have analytic counterparts.
For example,
MAX (column_1) OVER (PARTITION BY column_2)calculates the same MAX that you would get with
MAX (column_1)
GROUP BY column_2But without grouping.
(I suppose you'll still want to get only one row per group in your view, but there are ways to do that without using GROUP BY.)
If you need help, post:
some sample data (from the base tables),
the output you want from that data (that is, the contents of the view), and
your existing view definition.

SQL 2005 to Oracle 10g migration

We are migrating from SQL 2005 on Windows to Oracle 10g on Linux. If any one has experience with this kind of migration please share the steps involved.
Also is it possible to migrate subset of data from SQL to Oracle or is migrating entire data/schema the only option?
Any help or direction in this is much appreciated.Thanks in advance

Hi spulyala,
There is no clear and simple way of doing this.
-The online data move migrates from one java connection/table to another java connection/table so you would need to have the source table already filtered.
-The offline data move dumps the information out of SQL Server one table at a time, a where clause may be able to be applied manually at this stage, and loads the data in using Oracle sqlldr.
Of course you can filter and manipulate the tables within SQLServer before migration, within Oracle after migration, and delete table representations from with the tool.
