Checklist for migration from oracle 9i to oracle 10g DB

Hi all,
My previous DB was Oracle 9i.I want to migrate it to Oracle 10g DB.
So can anybody provide me the checklist for the same ?
Thanks in advance....

It doesn't matter how long this process may take to read the entire upgrade documentation. You are supposed to perform this procedure first on a testing environment prior to perform it against the actual production database, you can take all the time you need to customize trim and tailor the procedure to your particular environment requirements. Don't expect anybody else to provide a shortcut, you will find at the end it will take you more time to correct missing upgrade steps and you will -most probably- have to read much more google references and metalink documents that will size bigger than the upgrade guide.
I suggest you to read through the upgrade document, and don't look for shortcuts. I also suggest you to document issues you may find when performing the upgrade. In my particular scenario I had to deal with an ORA-04030 error, among other things after I performed an upgrade process. You may want to take a look at the not documented Issues I had to face after a production upgrade, and even though I read through the upgrade guide and performed several testing upgrades, there are issues such as user's actual workload that cannot be accurately measured in a testing environment.

  • Problems while migrating from mySql DB to oracle DB

    Hi All,
    I'm using sql developer tool to migrate from MySql DB to oracle DB. I followed the below steps.
    1) I've created oracle and mysql connections successfully.
    2) I've captured Mysql data and I'm able to see the captured model in ' Captured Models ' window. After that right clicked on the captured model and selected ' Set Data Mapping'. Selected ' apply ' button without changing anything. After that I've right clicked on the captured model and selected ' Convert to Oracle Model ' . It has shown the converting process. After some time it has shown conversion completed successfully.
    But converted model is not visible in ' Converted Models ' window.
    Can anyone kindly assist on how to migrate from MySql Db to Oracle DB?
    Thanks,
    Saty.

    Hi,
    We did mysql to oracle migration some time back and played with workbench tool and many other softwares available.
    However our experience was not so good with these tools, each tool had its own limitation and was not able to migrate 100% data. Even the speed of migration was too slow which would have violated our production SLAs.
    So after spending a month with these tools we finally decided to create our own scripts for data migration. We used tools like TOAD and SQL Yok to create the DDL for the tables and other DB objects.
    For the data migration we downloaded the mysql data in flat files and used sql loader to upload the same data in oracle. Even if this was a time consuming activity but this resulted in 100% data migration with no record getting failed and the time taken for this activity was around 6 Hrs in comparison to time of 24-28 Hrs that the workbench tool took.

  • Migrate from  Ingres DB to Oracle

    Hi Friends,
    I have to migrate from Ingres DB to Oracle and the application developed by Oracle Forms.How can we do this any process of docs.
    From my research,I came to know about Transparent gateways,But Oracle will support for this or not I'm not sure.Any such experience shared
    will be really useful.
    Regards.

    We have two more customers that currently are in the process of upgrading from MS SQL but as far as I know no one has actually performed an upgrade this far.
    If you want to upgrade to OIM 9.1 you will have to wait until the upgrade scripts are available (estimated arrival H2 2008 according to the latest info I have).
    If you would like to discuss this further send me an email on firstname.lastname@my_company.com (you can get the "variables" from my forum profile)
    Best regards

  • Migrating from SQL Server to Oracle 8i

    Hi all :),
    I am trying to migrate from SQL Server to Oracle 9i.
    I am using the Migration Workbench.
    Everything goes fine during Capturing phase, but while
    creating Oracle model the Workbench just hangs at
    "Mapping Tablespaces" for over three hours.
    (not exactly hangs in the sense that it responds to mouse
    events and I can abort the ongoing activity ...)
    What should I do ? Should I let it go on and see what
    happens.
    I follow each and every step as mentioned in the
    documentation ... but obviously I am doing something
    wrong. Any pointers ???
    However ... if I try to migrate to Personal Oracle 8 ...
    the migration goes fine from start to end ... just that
    the SQL Server triggers aren't successfully migrated.

    You may want to start by downloading the Oracle Migration Workbench. That generally does a reasonable job in moving the tables, stored procedures, etc. from SQL Server to Oracle. If your VB code is database agnostic, it should continue to work without any more intervention. Realistically, however, you'll rpobably have to at least tweak a few things that don't work the same way in the old ODBC/ OLE DB provider and the new one.
    The hard part of migrations like this is that you may need to revisit some of your architectural decisions if you want Oracle to perform well. There are plenty of things that one does in SQL Server (i.e. frequent commits) to improve performance that have the opposite affect in Oracle. Identifying and fixing these sorts of things tends to be the largest part of a migration like this. Unfortunately, I don't know of a resource that talks addresses all the possible gotchas here.

    Hi Khalil,
    Can you please e-mail [email protected] with answers to the
    following questions. We will try and investigate this.
    What is the structure of the SQL Server table?
    What is the structure of the Oracle table?
    Also, what character set did you create the Oracle database with?
    What codepage was the SQL Server database?
    Are the characters appearing as question marks in an application?

    Is it possible to migrate from Redhat Linux to Oracle Linux on servers in a Data Center that don't have an internet connection? If so, what is the process?
    In my case, tunnel.
    Have ssh. Can travel.
    Can you ssh into the server? Even via multiple hops? Then you can hook that server up to your Internet connection.
    Simple example. Your desktop have Internet connectivity via web proxy 10.1.2.3 on port 8080. Your desktop can reach the server via ssh.
    From your desktop, ssh into the server and reverse tunnel Internet connectivity
    ssh -R 7777:10.1.2.3:8080 root@server
    This creates a tunnel on port 7777 on server - and tunnel traffic on that port to your desktop. Arriving at your desktop, that tunneled traffic is send to the web proxy server 10.1.2.3 on port 8080.
    On server, set the proxy variable so that yum, wget and other Internet usage/dependent commands know how to reach the Internet. And the proxy on the sever is the tunnel on port 7777. Thus:
    export http_proxy=http://127.0.0.1:7777
    export https_proxy=https://127.0.0.1:7777
    Use wget google.com to test tunneled access to the Internet. And Bob is not only your uncle, but gives you slack.

  • Forms migration from 2.0 to Forms 10g/11g

    Hi,
    I want to migrate from forms 2.0 to 10g/11g. I know the migration path is 2.0->4.5->6i->10g/11g . I want to know is it feasible to do the migration from 2.0 to 10g/11g. what are the recommendations.
    Thanks & Regards,
    Noman

    PITTS claim to be able to migrate forms from Forms 2.3 onwards.
    http://www.pitss.com/solutions/pitsscon-solutions/forms-to-forms/
    It depends on how much you want to spend...
    However, if you're looking to do it yourself...
    Do you have access to developer versions of Forms V3.0 or 4.5? It's easier if you go from 2.0 -> 3.0 -> 4.5/6i -> 10g. Each version has its own migration utilities, but they gradually remove support for earlier versions. Version 2 (2.3) triggers can exist in version 3, but not in later versions.
    Do you have experience of Forms 6i or 10g? If not, you have the scope to re-write the application in the language of your choice. The Oracle website has a number of articles on migrating from Forms 3 and 6i, but not from earlier versions, so it depends on your current knowledge as to how you want to do.
    I've migrated Forms 3.0 (with 2.3 style triggers) to 10g by hand. It requires an understanding of how Forms used to work compared to how it works now. You will basically be creating your new application from scratch (depending on what you have been able to upgrade) based on the the blocks and items of your old forms. Your task will be so much easier if you have the intermediate Forms developer tools (4.5/6i).
    You'll also be upgrading your database. I assume that you are on Oracle 6/7.

  • Link/checklist for migrating applications from Oracle 9i to Oracle 11g?Help

    Hi all,
    We need to perform an impact analysis on migratiing an application from Oracle 9i to Oracle 11g. Does any of you have a detailed checklist to follow, in terms of queries, PL/SQL statements, optimizer etc. etc., when attempting this migration. We require something more specific from the application point of view rather than a DBA point of view.
    Additionally, we have queries written extensively with rule hints. Should there be a special consideration for the same since now we are moving to CBO in 11g
    Even if any one has a link, that would help. Thank you so much!

    Hi Nikhil,
    Thanks Xaheer,You're welcome :)
    I'm going through the link: http://download.oracle.com/docs/cd/E11882_01/server.112/e10819/toc.htm
    But it still mentions stuff from a DBA angle. I need from an application angle.
    Do I need to change my queries taht are current written with RBO? Do I need to change Pl/SQL blocks ?Please refer tech below notes:
    *1)TROUBLESHOOTING: Server Upgrade Results in Slow Query Performance -- 160089.1*
    *2)TESTING SQL PERFORMANCE IMPACT OF AN ORACLE 9i TO ORACLE DATABASE 10g RELEASE 2 UPGRADE WITH SQL PERFORMANCE ANALYZER -- 562899.1*
    Before upgrading your production database, please perform upgrade of test database and do complete testing.
