IBM DB2 to Oracle Database Migration Using SQL Developer

Hi,
We are doing migration of the whole database from IBM DB2 8.2 which is running in WINDOWS to Oracle 11g Database in LINUX.
As part of pre-requisites we have installed the Oracle SQL Developer 4.0.1 (4.0.1.14.48) in Linux Server with JDK 1.7. Also Established a connection with Oracle Database.
Questions:
1) How can we enable the Third Party Database Connectivity in SQL Developer?
I have copied the files db2jcc.jar and db2jcc_license_cu.jar from the IBM DB2 (Windows) to Oracle (Linux)
2) Will these JAR files are universal drivers? will these jar files will support in Linux platform?
3) I got a DB2 full privileged schema name "assistdba", Shall i create a new user with the same name "assistdba" in the Oracle Database & grant DBA Privillege? (This is for Repository Creation)
4) We have around 35GB of data in DB2, shall i proceed with ONLINE CAPTURE during the migration?
5) Do you have any approx. estimation of Time to migrate a 35 GB of data?
6) In-case of any issue during the migration activity, shall i get an support from Oracle Team (We have a Valid Support ID)?
7) What are all the necessary Test Cases to confirm the status of VALID Migration?
Request you to share the relevant metalink documents!!!
Kindly guide me in-order to go-ahead with the successful migration.
Thanks in Advance!!!

Hi Klaus,
Continued with the above posts - Now we are doing another database migration from IBM DB2 to Oracle, which is very less of data (Eg: 20 Tables & 22 Indexes).
As like previous database migration, we have done the pre-requirement steps.
DB Using SQL Developer
Created Migration Repository
Connected with the created User in SQL Developer
Captured the Source Database
Converted Captured Model to Oracle
Before Translation Phase we have clicked on the "Proceed Summary"
Captured Database Objects & Converted Database Objects has been created under PROJECT section.
Here while checking the status of captured & converted database objects, It's showing the below chart as sample:

We have seen only "Missing" in the chart, also we couldn't have any option to trace it in Log file.
Only after the status is VALID, we can proceed with the Translation & Migration PHASE.
Kindly help us how to approach this issue now.

PDP pages do not get restored in database migration

Hi All,
I have an issue while performing database migration. Let me explain the scenario. The issue is that I had migrated 4+1 databases, i.e., 1 Content db and 4 Project Server DBs. We have only 2 site collections listed in DB, PWA and Top level root site collection,
obviously when I restored the content DB, the PWA site is also restored. So I deleted that as I need to provision a new one with the same name. So after restoration, I provisioned a new PWA site with the restored databases. It provisioned perfectly and our
data like projects, custom fields, etc are present. Also EPT pages are listed but they are not working reason being PDP pages are not restored in the migration. I tried this migration on 2 separate environments as well apart from this one and same is the case
in all restoration. Though there are ways to get the PDP pages like using Playbook tool or configuring Manually again, but as per the concept it should be migrated along with the content database.
Can anyone please help in such situation as how can we get the PDP pages in database migration? Is there anything that I am missing?
Thanks, Sumit Gupta SharePoint Consultant MCP, MCTS, CCNA

Hi,
The PDPs reside in a document library within the PWA site. You mentioned above when you did the 4+1 restore you deleted the PWA site, the main benefit of doing a 4+1 is that you don't lose the contents of your PWA site and effectively wire it back up on
the new instance.
If you restore again, this time, do not delete the PWA site and perform the reprovision, this will take your four Project server databases and then wire them back up to the PWA site (which includes your PDPs).
In answer to your other question, yes Playbooks can be used to move PDP's between environments.
So in short, don't delete the PWA site post content DB migration :)
Hope this helps.

Steps to migrate Project Server 2007 from SQL Server 2005 to SQL Server 2008?

We need to migrate Project server 2007 from SQL Server 2005 to SQL Server 2008.
1. Is it as simple as doing backup and restore of databases and pointing Project Server to the new DB server? Or there are some specific steps that should be followed?
2. Article at
http://technet.microsoft.com/en-us/library/dd207290(office.12).aspx is about moving databases from one DB server to another (same versions). At one place, it mentions to
backup all databases but at another place it mentions that
You should only back up the Draft and Published databases from the source database server.
What should be done when moving from 2005 to 2008?
Regards,
Amit
Gupta

High Level step you can get this form Tech net or MSDN too
Shut down the SharePoint servers (App / Web)
backup all of the SharePoint and Project
Server databases from the SQL 2005 server
copy these over to the new SQL 2008 server and restore all of
the databases with the same names
script out all of the logins used by SharePoint/PS from the SQL 2005 server and create these on the SQL 2008 server
script out the Delete expired sessions SQL job from the SQL 2005 server and create this on the SQL 2008 server - or create them manually on the SQL 2008 server
repoint the SQL server DNS Alias from the SQL 2005 server to the SQL 2008 server, if SharePoint and Project Server was installed using the actual SQL server name and no alias, you can create a DNS alias for the old SQL 2005 server name that points to the SQL
2008 server. This is so that the SharePoint servers can still connect to the same SQL server name
Start up the SharePoint servers

Reg: Universe Designing (Migration Project)

Hi Gurus,
I need Informtion related to the migration project.
Migrating BO 5.1.7 to BO XI R 3.1.
the old universe with old database is structured as.
Eg: PTKEN as table name and objects as PTKEN.WASId
the new ( migrated universe ) has the database structure as
Eg: KEM_LKP_PTKEN as table anem and objects as WASId
What the process has to be done to change all the tables in the universe with the new database...
Regards
L K Vepuri
Edited by: L K Vepuri on Feb 28, 2011 3:56 PM

Hi Mr. Vepuri,
If the table name is changed at the universe level then follow the below steps.
1. Open the universe in the designer
2. Right click on the table which has been modified and rename it with the changed name.
3. Click on the View>> Refresh Structure.
4. and check whether it throws any error message or not.
For Object PTKEN.WASId--- what does it mean?
Is it column name or object name at universe level.
Object definition of each object is visible as Table_Name.Column_Name.
If you want to change the object name then you can rename it.
In order to propagate the changes made at a database level to universe level always click on the View >>refresh structure
Hope it helps.
Thanks,
Sands

Zero-downtime Database Migration tool ?

We are exploring\evaluating tools provided by Oracle (or its partners) that ensures Zero-downtime Database Migration. Migration should include:
- Migration of data from one version of the application to another version with or without changes to the database schema.
- Migration of data from staging to production where staging was used for beta testing to host customers who created live data which need to be migrated to production. (Oracle to Oracle, SQL Server to Oracle, MySQL to Oracle, etc)
- if a data type changes (say int to varchar) in staging database for a particular column in a table, the change migration should happen in the production database as well
- if a column is added\deleted in a table of staging database, the same table alteration should migrate to production database
- records in production database should not be deleted\truncated during data\schema migration
- maintain zero-downtime
By Zero-Downtime we mean: both the source and the target should be up and accept updates in real time during migration process. This should again be synced across and hence help to eliminate downtime during migration between various vendor databases.
We are not looking for any ETL product, but out-of-the-box products like GoldenGate and Celona that ensure Zero-downtime database migration.

Hi,
I dont think that there is any easy answer. It looks like huge project so it should be done part to part.
If I understand
1) you have create staging database with all changes
2) production is in old structure
3) now you want to merge this two databases into one? Or applly all changes form staging to prod?
I see there one solution clone your staging and create new prod. Whenit's donw switch connection to your new prod database.

Tom

How to migrate Project Server 2003 to Project Online?

Hi Guys,
Is it possible to migrate Project Server 2003 to Project Online directly? I heard we normally have to take 3 hops for this;
1. Project Server 2003 - Project Server 2007 migration.
2. Project Server 2007 - Project Server 2010 migration.
3. Finally, Project Server 2010 - Project Online migration.
Is there a migration tool we can use to simply jump from Project Server 2003 to Project Online?
Thank You,
Arnel

NO, directly you can not migrate. You have to follow the sequence
1. Project Server 2003 to project server 2007
2. Project Server 2007 to project server 2010
3. Project Server 2010 to project server 2013 online.
Unfortunately we dont have nay tool which will help us to do this .
Microsoft has a virtual machine (2007) that you can use to jump to 2007. Basically the databases of 2003 must be converted to 2007. Once this is done (database at 2007) you can use this database as start point to be converted to 2010.
Microsoft has virtual machine for 2010 too if you want you can use it rather than creating your own environment.
Don't use 2007 backward compatibility mode in 2010, we experienced some issues with it.

Migration Effort estimation.

Hi All,
Now days we are getting a lot of enquiries regarding the migration of SharePoint 2007 to SharePoint 2013 from Customers. Biggest challenge I am facing in migration is, the cost of migration.
We are using the Content DB upgrade approach for Migration.
Do anyone know any free tool that can help me in migration efforts estimation?
Regards Restless Spirit

It will help but you might end up in errors if you have lots of customizations. so I would say the best approach is
migrate VIA SP 2010 and then to SP 2013 from SP 2007. you need to plan in such a way that migration application/database by application. should perform no of dry runs in the test envionments and find out what are the potentiall issues and making note of
them.etc. by direct approach you will not have issues interms of data loss and customization and metadata, effort is more but it will be good and smooth, where as with quest or any other third party tool cannot not say you will have smooth migration
depends on my past experience with it.
Thanks, Ram Ch

Export Migration Project

Hello,
is there a possibility to export a migration project?
Best regards
Tareq

Hi Tareq,
Unfortunately there is no option to export a Migration project currently. In the meantime, once you've got access to your migrated Database schema objects (preferably as a DDL script) and also all the necessary Migration files e.g. for an MS Access Migration, that would be a SQL script e.g. Northwind.sql and for an Oracle Forms conversion, that would be XML files for Form Modules/Menus/Object Libraries and Oracle Reports, and PLD files for converted PLLs, then you can very easily re-create the Migration Project in a different workspace. I appreciate that the selections you may have made in the Migration Project cannot be exported, so we could possibly look at addressing this in a future release.

Hilary

Access Migration Error Creating Migration Project - string literal too long

I get this error when attempting to create an MS Access Migration Project:
ORA-20001: GET_BLOCK Error. ORA-20001: GET_STMT error. ORA-20001: Execution of the statement was unsuccessful. ORA-06550: line 8, column 8: PLS-00172: string literal too long &lt;pre&gt;begin &amp;lt;br&amp;gt;declare &amp;lt;br&amp;gt; p varchar(32767) := null; &amp;lt;br&amp;gt; l_clob clob; &amp;lt;br&amp;gt;begin &amp;lt;br&amp;gt; dbms_lob.createtemporary(l_clob,FALSE, dbms_lob.session); &amp;lt;br&amp;gt; dbms_lob.open(l_clob,dbms_lob.lob_
I suspected the 'string literal too long' was due to a very long code section in the Exporter .sql file -
So I edited out that code except - essentially by cutting the macro code within the quotes, cutting down that code module.
Same error.
Any suggestions on what else may be causing this?
Thanks - Karen

I found it - two other big long ugly macros that I had to cut out as well. Then the migration project created just fine. Thanks for the moral support :)

Oracle E-business suite database migrate from AIX to Linux

Oracle 11i application database migration from single Aix instance to oracle Linux cluster RAC.
What is the easy way to migrate?
Migrate single instance from aix to linux cluster.
OR
Migrate single instance from aix to linux cluster RAC.
We have installed oracle Linux cluster.
Please help me which way I can go with RAC.
Thanks
Prince

Migrating to a single instance will be the simplest. The migration itself will not be much different between the two because you're migrating from one platform to another. The options you have available are, the traditional IMP/EXP, datapump, and RMAN to migrate to either a standalone or RAC environment. The difficulty will be in creating a RAC environment and a little a few extra steps in the RMAN restore. Working with RAC will make things harder, but the actual migration is similar. The steps to IMP/EXP, whether it's traditional or Datapump will be no different. However, standing up a RAC database will be.

Creation of Database View , Projection View

Hi ABAP EXPERTS,
Can anyone plz send me the step by step creation of DATABASE and PROJECT VIEWS. Just steps by step explanation will do , screen shots will be more than appreciated.
Kind Regards,
Sunil Ranal.

Database View (SE11)
Database views are implement an inner join, that is, only records of the primary table (selected via the join operation) for which the corresponding records of the secondary tables also exist are fetched. Inconsistencies between primary and secondary table could, therefore, lead to a reduced selection set. In database views, the join conditions can be formulated using equality relationships between any base fields. In the other types of view, they must be taken from existing foreign keys. That is, tables can only be collected in a maintenance or help view if they are linked to one another via foreign keys.
Check this link for database view creation.
http://help.sap.com/saphelp_40b/helpdata/en/cf/21ed06446011d189700000e8322d00/content.htm
Projection View
Projection views are used to suppress or mask certain fields in a table (projection), thus minimizing the number of interfaces. This means that only the data that is actually required is exchanged when the database is accessed. A projection view can draw upon only one table. Selection conditions cannot be specified for projection views.
Check this link for Projection view creation.

Best practice for database migration in 11g

Hello,
Database migration is required due to OS change. Here, I have two database instances say A and B in the old server where RDBMS_VERSION is 11.1.0.7.0. They need to be migrated into a new OS where the oracle has been installed with version 11.2.0.2.0.
Since all data + objects need to be migrated into the new server, I want to know what the best practice is and how to do that. Thanks in advance for your necessary guidance.
Thanks and Regards,
Prosenjit

Hi Prosenjit,
you have some options.
1. RMAN Restore: you can restore your database via rman to the new host, and then upgrade it.
Please follow instruction from MOS Note: RMAN Restore of Backups as Part of a Database Upgrade (Doc ID 790559.1)
2. Data Guard: check the MOS Note: Mixed Oracle Version support with Data Guard Redo Transport Services (Doc ID 785347.1)
3. Full Export / Import (DataPump)

Oracle Database Migration Verifier - Can it be used for diff table structur

Hello,
We have re-engineered the existing sybase tables to a new structure in Oracle for few of the tables.For example a table in sybase is normalized to two tables in oracle.In these cases can the "Oracle Database Migration Verifier" be mapped such that the columns in one table in sybase be mapped to two table is Oracle with their respective column names.
In a gist can the tool be used even if the structure is not the same in the source and targer databases.
Please let me know if you need more clarifications regarding my query.
Regards,
Ramanathan.K

not really. The DMV was a simple tool for verifiying that what you now had in Oracle was what you had in Sybase. It does not do what you are expecting.
