Migration Issues from Informix to Oracle (datetime format)

Hello, i am performing a Migration from Informix to Oracle, drive by Migration Workbench, i have an error migrating data from datetime and date fields. I suppose its related by datetime and date format, cause the error tells "Incorrect day or month" when i am migrating data from informix. Targets Oracle database date format is DD/MM/YYYY and source`s Informix database date format like MM/DD/YYYY. Is there any way, in OMW, to specify the mask of datetime or date format to convert date strings from informix to oracle format? Or have i got migrate offline and modify control file to do that with sql*loader?
How can i do that?
Example, especify to_date('....', 'MM/DD/YYYY H24:MI:SS') format for migrating informix datetime fields to Oracle.

The problem i have is, several tables witch contains date and datetime fields, at the same table in informix, by migrating drive by omwb to oracle, the date format i receive from informix at reading is DD/MM/YYYY and datetime format receiving is HH24:MI:SS. Migrating date and datetime types from informix to date, both types to date in oracle, i get an error while matching DD = HH24, MM = MI and YYYY = SS where nls_date_format is DD/MM/YYYY and, the same error matching HH24 = DD, MI = MM and SS = YYYY when nls_date_format is HH24:MI:SS.
If i set nls_date_format as "DD/MM/YYYY HH24:MI:SS" i get the same error, cause reading data from informix results in data format "DD/MM/YYYY" for date fields and "HH24:MI:SS" for datetime fields.
I have more than 200 tables in informix with this problem to migrate to oracle, i can solve by migrating offline, modifying datacontrol file to casting to_date format, but over 200 tables, 200 datacontrol files... is there any way for solving that by online migration in omwb?

Migrating Data from Informix to oracle

Is it advisable to migrate the whole schema from Informix database to Oracle 10g or migrate each table using sqlldr. If the data model is not exactly same then can we export data from informix and import the dump file in Oracle 10g.

You can use Generic Connectivity. It is a free feature of the database available on Windows, HP, AIX and Solaris and Linux (v10g).
There is also the transparent gateway for Informix however it is not certified with Informix 7.2. It is certified with 7.3 and higher.

Migration from Informix to Oracle

Hi,
Could anybody share the case studies/plan/docs related to migrating data from Informix to Oracle.

Hello,
The Oracle® Migration Workbench Reference Guide for Informix Dynamic Server Migrations is avalaible at
http://download.oracle.com/docs/html/B16022_01/toc.htm
Also, you will find a lot of informations on the Informaix migration technet page at
http://www.oracle.com/technetwork/database/migration/informix-085032.html
Even if a lot of samples are Microsoft SQL Server based, they also apply on an Informix migration as well.
Hope it will help

Migrating from Informix to Oracle 11g

Hi,
I have downloaded the Migration workbench, and the plug-ins Inofrmix7.jar from http://www.oracle.com/technetwork/topics/index-095746.html. Kindly could you please tell me from where i can download the ifxjdbc.jar. Are these files same with different name.
Regards

Hello,
What you need is the Informix Dynamic Server JDBC Driver, version 1.4 JAR file, ifxjdbc.jar.
This driver is shipped with the Informix Dynamic Server software. I am not sure you can download it freely.

Migrating data from Informix 7.2 to Oracle RDBMS

I've got several applications running on an Informix 7.2 database and I need to migrate this data to an Oracle 8.1.7.4 database. Is there a gateway product available to aid with getting this data migrated. We tried Oracle Migration Workbench but Informix 7.2 is not supported. Any help with getting this done is appreciated. I don't want to keep these apps on Informix!!!

Migrating applciation from weblogic to oracle 9i application server(OC4J)??????

Hi,
I am migrating my ejb application from weblogic to oracle 9i application server.What changes are needed to be made in code and what configuration changes are required.
In my application i use a couple of session beans wherin a session bean calls the method of the other session bean which acceses the database.I am using a jdbc thin driver for the database connection. is it possible for a session bean to call a method of another session bean which access the database??This concept works well in weblogic where the current application is running.
The problem is that while migrating the application to the orion server, it gives an OrionCMTException ...
memory leak..etc.
Could any one clarify.
Thanks in advance!!!

Hi Avi and Harrison,
Cease Fire avi!!!!.First of all let me clear the issue of posting the same problem twice.Well, when i mentioned the problem the first time , i found the title session bean deployment was not right and few people would look into it as it was a common problem so i thought it would be appropriate if i mentioned the title correctly , so i posted the query again with the change in title.
Now coming to the answer for ur questions.
The platform used is MS Windows NT.
The (OC4J) version is 1.0.2.2.1.
I am not using JDeveloper.
The database is oracle 8i and i am using the thin driver.
The beans to be deployed are stateless session beans.
The client involved is a web client i.e a jsp application.
The first session bean is as follows.

But if the DBUTILITY session bean is changed to a simple bean and accessed the code works fine and i am able to retrieve the data.Is the problem there because u one session bean cannot access a database connection method from another one or could it be because of the driver???
I hope i am clear.Please revert back in case any more references are needed.

Migrate data from orcle to oracle

Hi ,
A) Using oracle workbench tool can we migrate data from oracle 9i to oracle 10g ?
B) Is this tool used only for migrating data from non-oracle source to Oracle db ?
regards
thiru

Dear Barry
Thanks for the valuable information provided, it had answered few of my doubts.
i am much thankful to you if you can help me in this regards.
Does Oracle own any GUI based tool similar to Microsoft-DTS to Extract & transform data from one Oracle DB to other Oracle DB ?
The source DB (oracle 9i) is not properly normalized , the data from source is moved to a Normalized 10g DB with new attributes(based on new requirements) added to these tables . Some tables from source are splitted into 2 or more in target (oracle 10g) database. I have scenarios like
My text below quotes "SOURCE" AS UNNORMALIZED DB & "TARGET" as new DB which is NORMALIZED.I need to migrate data from SOURCE to TARGET
1) A single row in SOURCE be migrated to multiple rows across one or more
tables in TARGET.
2) A multiple rows in single column in SOURCE be migrated to single row and
multiple columns in TARGET.
For the above mentioned scenario sql*loader /external table/export & import or transportable tablespaces can be used as mentioned by you. but considering the ease of use and the complexity is there any GUI tool which oracle has for data migration from oracle db to oracle db.
your advice will be much help to me.
Thanks
Thirumaran

From Informix to Oracle

Hello,
We have a requirement to migrate an Informix (character based) application to a web based system (to Oracle Forms or Java/J2EE).
My question is, there any tool to do that kind of migration?
Thanks in advance,
Arun.

Hi there,
I faced the same problem a couple of weeks ago. First issue was that the Migration Workbench did not suport the Informix version I was using (7.23).
The migration path I took was the one you mentioned in your question (informix db export, oracle sql loader). However, it was quite tricky.
First of all, you need to export the informix database into text files:
$ dbexport CA1 -q -o /tmp
CA1 is the informix database to be exported. This results in a CA1.sql file which stores the informix schema and a couple of .unl flat files (one for each table)
If you have any more question, feel free to contact me...
Cheers, Stefan

Migration Issue from 11.1.1.4 to 11.1.2.

Hi All,
We developed our app using JDev 11.1.1.4 and now we have migrated our code to 11.1.2. Now we are facing the following issue.
We are showing some information messages using FacesContext.addMessage(), as shown below:
FacesContext fctx = FacesContext.getCurrentInstance();
FacesMessage message = new FacesMessage("For the current selection criteria, the estimated row count is " + estRowCount + ". We recommend to export data to excel for row count greater that 150.");
fctx.addMessage(null, message);
Earlier, the popup used to be just big enough to show the message content.
Now in 11.1.2, the popup is coming up bigger in size, and we dont want it.
Is there any configuration where we can control its size and variations?
Thanks,
Lalit.

I am seeing some changes in popup behavior in 11.1.2 from earlier release.
Earlier, in 11.1.1.4, when we use showpopupbehavior to render popups, we set the Resize property to ON for panelWindow tag dropped on popup, as earlier they were not stretched based on the content.
Now, the popups are stretched automatically based on the contents rendered in them so we reset the resize property on OFF for panelWindow tags. Otherwise, scrollbars appear in popups where Resize is on and content is more than default popup size. This is first change I observed and after setting Resize to off, we are ok.
However, second issue is more serious where when we are rendering information popups programatically by adding messages to facesContext. The popup size in this case has increased by default.
Earlier they used to come just big enough to render the content.
Now, by default their size is bigger and fixed, and I don't know how to configure its size.

Migrate datas from RDB to Oracle 10g

The applications that use the RDB database are being re-write with Forms based on an Oracle database.
Of course, before we use the new application, we will have a step for moving datas from old tables in Rdb to the new tables (new design) in Oracle (developpers are working on sql scripts for that). But when the new applications with Oracle db will be in production, I would like to save datas (datas as datas) from Rdb in an Oracle database with the same struture as the rdb structure (same tabels, with same columns and same datas in). The idea is we will be able to verify datas through SQL.
Do you have any idea ?
Thank you
AnneMar

Hi AnneMar,
there exists a Metalink note that serves as a starter for such a migration:
Note 135929.1: RDBPROD: Advice on Converting from Oracle Rdb to Oracle RDBMS
For your convenience I am pasting that note here.
Regards
Wolfgang
PURPOSE
To provide general advice on migrating from Oracle Rdb to Oracle RDBMS
SCOPE & APPLICATION
This advice is intended for people who have already decided to convert, and are starting to plan how to do it. It provides a broad outline of how it can be done and some of the things to consider.
Advice on Converting from Oracle Rdb to Oracle RDBMS
General notes
* The longer you leave it the easier it is likely to be. The SQL interfaces to Rdb are growing closer to those for RDBMS, particularly OCI Services for Rdb.
* Converting the database will probably be the easy part. The applications are likely to require more work.
* A staged approach is more likely to be successful than trying to do everything in one go.
A possible strategy for converting
1. Install OCI Services for Rdb. Pick a small application, or one that needs rewriting anyway. Convert the application using the method and tools of your choice to access the Rdb database via SQL*Net for Rdb. If unsatisfied with the results, you can repeat this with alternative methods or tools, until you find one that works for you.
2. Install RDBMS. For those tables used by applications converted to use OCI Services, create database links. Point the converted application to the RDBMS database instead of the Rdb one. This step can be done whilst other applications are being converted. No data is yet stored in the RDBMS database, so any problems that arise with it, possibly due to lack of appropriate DBA experience, can be worked around by just pointing the programs back at the Rdb database.
3. Now you have a choice.
1. Gradually move the data into the RDBMS database. First new tables, then tables only accessed by applications that have already been converted. This has the advantage of taking one step at a time, so it would be easy to back up temporarily if a problem is found. The main disadvantage is that now that the data is spread over two databases your backup and recovery strategy will be more complicated.
2. Finish converting the applications. Then transfer all the data over in one go. If there is a lot of data, then going back would be a big job, so there is more risk.
Alternative common interfaces
Besides OCI Services there are several other APIs that applications could use to access Rdb or RDBMS transparently.
* JDBC - If your applications are written in JAVA or you want to rewrite them in JAVA
* ODBC - If your applications run on Windows
* .NET - If your applications run on Windows
Techniques for converting a database
* Transferring Metadata Extract the metadata using RMU/EXTRACT. Cut down and edit the output to produce a script to use to create the corresponding RDBMS objects.
* Transferring data
For small tables,
INSERT INTO rdbms_table SELECT columns FROM rdb_table;
(using dblinks to the rdb database and SQL*Net for Rdb)
For large tables, use RMU/UNLOAD to create a delimited file and then load that into RDBMS using SQL$Loader.
* Keeping data current in RDBMS while testing the transfer can be done using the Logminer Option in Rdb.
Notes
1. OCI Services for Rdb was formerly known as SQL*Net for Rdb and is part of Oracle SQL/Services. Though this is structured as a separate product from Oracle Rdb no additional license is needed.
2. Some limits are different between Rdb and RDBMS.
For example: in Rdb table and column names can be 31 bytes but RDBMS only allows 30.
3. The RMU/EXTRACT command can write the SQL definitions of objects within a Rdb database to a text file.

Migration issues: from BOXIR2 - BOXI3.1

Hi,
We are migrating BOXIR2 - BOXI3.1.
after migration, i involved in testing and comparing results with older version.
But some of the reports are continously giving different kind of error.
for eg:
1) one time refreshing the report but giving no data to fetch but the same report is having data.
2) some time not refreshing and giving : Error on excute (WIS 10901)
3) to debug, i tried creating the same reports by adding objects one by one - this time report is refreshing but the results are mismatching.
we have remigrated the universe and reports, recreated the ODBC connections, restarted the servers, services, reinstalled the Oracle client but nothing worked out.
Please guide/suggest me to resolve the problem.
