Migration From Microsoft Exchange to Oracle

Hi
I am evaluating Exchange to Oracle Colaberation Suite - I would like to hear of any views on the process you completed - are you happy or unhappy - How painful was the process. Any comment would be good

For the end user this should be transarant as they should use their favourite client (eg MS Outlook, Thunderbird, etc). It is easy to manage when you have sufficient Oracle skills (db and AS).
Of course you have other components (calendar, RTC, Portal, News, Discussion, etc) in the OCS.

Hi Zuhair,
If you give details of the problems you are still having then we should be able to get SQL*Developer to work.
However, if you don't want to use SQL*Developer then the following options are taken from note 393760.1 available in Metalink if you have access to that -
1. Use a gateway that supports the non-Oracle database or generic connectivity if a third party ODBC driver is available to do a -
'create Oracle_table as select from non_oracle_table@database_link'
for each table. You would then have to manually create all the other objects (views, indexes, stored procedurs etc) and permissions etc that existed in the non-Oracle database.
2. Use the SQL*Plus COPY command to copy data from the non-Oracle database to the
Oracle database using a gateway or generic connectivity. The syntax is as follows:
COPY FROM username/password@oracle_sid -
INSERT destination_oracle_table -
USING query;
The following example selects all rows from the EMP table in the non-Oracle database and
inserts them into the local Oracle EMP table:
COPY FROM SCOTT/TIGER@ora10 -
INSERT EMP -
USING SELECT * FROM SCOTT.EMP@gateway;
where "gateway" is the database link created for the gateway.
3. Load the non-Oracle data into flat files and use SQL*Loader to put the data into Oracle tables. Again manual
work is required for the other objects.
4. Contact the Oracle Product Technology Services (PTS) group for assistance. See the webpage -
http://www.oracle.com/technology/tech/migration//workbench/index_sqldev_omwb.html
5. Use a third party migration tool. See -
http://www.oracle.com/technology/tech/migration/isv/third_party.html
6. Use JDBC to connect to the non-Oracle database and Java in the Oracle database. This method will work but it is not suppported by the JDBC team.
=========
The amount of work involved will depend on the number and size of Access tables that you want to migrate.
Regards,
Mike

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.

Help me please to migrate from MS SQL to Oracle

Hi all,
we are in process of migration from MS SQL to Oracle.
Please help me to perform the same in Oracle:

This needs the user to have access on all_objects view and it will limit the result upto the numbers of objects returned by the all_objects view.

Migrate from sas spds to oracle 11gr2

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.

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?

Accesssing Mailboxes,Mail Information from Microsoft Exchange

Hi,
I want to know how we can access the mailbox information and information of a particular mail like messagebody,headers from Microsoft Exchange using JNDI. Any body who knows let me know whether it is possible and if yes how to achieve this.
I already can able to get user information and exchange configuration.
Waiting for a quick reply.
Thanks.

I want to assume you are talking about reading a Mailbox information(Attributes) from Microsoft Exchange using JNDI.
If this is what you mean, I say it is very possible.
The JNDI Tutorial will help you out. These are the step u will need to take.
1. Define a collection item you will use to hold your exchange server information and provider information. The Hashtable component is mostly used.
2. Create an intance of your Exchange Server context.
3. You can then do a search for the mailbox recipient in the context server.
4. you can then begin read the mailbox attribute from the Attibute object you had search for in step 3 above.
You should please use look thru the JNDI Tutorial topic Naming and Directory.
