Informix SE 7.x -- Oracle 8i conversion

We are currently attempting to convert an Informix SE 7.x
database to Oracle 8i. Our plan was to use the scripts to first
convert it to Oracle 7, and then use the conversion assistant
that comes with 8i to convert the O.7 to O.8i. However, a hitch
has ocurred as the scripts only seem to support Informix Online
7.x. If anybody out there could offer a few pointers on how to
modify the scripts to allow this (or can offer any other
information, for that matter), it would be greatly appreciated.
Cheers,

Hi Gerhard,
The 7.x scripts may be far removed from what you need. It depends
on how much the Informix data dictionary has changed between the
two versions.
The scripts work by extracting the data dictionary definitions of
exch schema object. They then perform some relatively simple
migrations e.g. datatypes, and then generate schema creation
scripts for Oracle.
If you are thinking of writing scripts, I would suggest that you
start with trying to extract tables first. This should be
relatively straightfoward and give you a feel for extracting the
rest of the objects.
Regards
John

Problem when migrate Informix 9.4 to Oracle 10.2 by use OMWB 10.1.0.4

Hi,
When I use OMWB to migrate Informix 9.4 to Oracle 10.2, I encounter many errors as follows:
===========================================================
java.sql.SQLException: ORA-12899: value too large for column "ROGER"."ABB_FILE"."ABB04" (actual : 32, maximum: 30)

==========================================================
But when I check the Source column length, it is not long then column length in Oracle actually. I don't know why....
Does anybody have idea? Thanks!

Hi Donald,
Thanks for your reply.
"ROGER"."ABB_FILE"."ABB04" means in user "ROGER" schema, have a table "ABB04", and have a column named "ABB04".
So the column's name is "ABB04", not exceed 30 characters.
The table's description in Informix as follows:
create table "roger".abb_file
abb00 char(2),
abb01 char(12),
abb02 smallint,
abb03 char(24),
abb04 char(30),
abb05 char(6),
abb06 char(1),
abb07 decimal(16,3) not null ,
abb08 char(10),
abb11 char(15),
abb12 char(15),
abb13 char(15),
abb14 char(15),
abb15 char(4)
And the table in Oracle's description:
CREATE TABLE "ROGER"."ABB_FILE"
     "ABB00" VARCHAR2(2),
     "ABB01" VARCHAR2(12),
     "ABB02" NUMBER(5),
     "ABB03" VARCHAR2(24),
     "ABB04" VARCHAR2(30),
     "ABB05" VARCHAR2(6),
     "ABB06" VARCHAR2(1),
     "ABB07" NUMBER(16, 3) NOT NULL,
     "ABB08" VARCHAR2(10),
     "ABB11" VARCHAR2(15),
     "ABB12" VARCHAR2(15),
     "ABB13" VARCHAR2(15),
     "ABB14" VARCHAR2(15),
     "ABB15" VARCHAR2(4)

Migration from Informix 9.4 to Oracle 10g

We have to perform a migration from Informix 9.4 to Oracle 10g. Many tables, many data and many stored procs.
We use the Online mode and the imports finish with any errors, but it has not recovered any stored procedures or we can't view the Informix Stored Procedures in the Source Model in the workbench.
In the importation log appears as no found procedures, but under owner informix are all procedures.
What we can do?

In the 10.1.0.4 version of the workbench we create an informix user who will have all the stored procedures.
If you want these migrated as another user you can right click on the user in the oracle model and rename it for a start.
If this is a large migration, I would recommend the following.
1. generate the ddl for the oracle database.
2. for the users, that will be created, move the objects to the users that you want these in.
3. Make sure that the privileges that a particular user has is appropriate to use the data and execute the stored procedures if necessary.
This tool is not just a one shot deal.. It will bring the informix db over to Oracle, but you need to verify the structure and the logic of the stored procedures as being correct.

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'
)

Oracle Assets Conversion Release 12

Hello Experts,
I am going to develop the conversion program for Oracle Assets Conversion for release 12. I am new to Fixed Assets concepts.
Could any one guide me what are all the steps to be followed. I understand by studying the user guide that there are 5 different ways to perform this Oracle Assets conversion.
1.Adjusted current earnings(ACE)information
2.Budget Data
3.Mass addtions of Assets
4.Production Information which is typically related to depreciation. and
5.Physical Inventory data.
Since ,as of now I don't have any requirement from my client. They just said to have a process developed to import the data into oracle apps using Oracle asset conversion using SQL loader.
Any Sample codings will be a great help for me.
Thanks,
Ravi.

Hi Nathalie,
We currently do not have such a tool within Oracle.
However, one of our MTI (Migration Technology Initiative)
partners may be able to help you.
Go to the following URL
http://technet.oracle.com/tech/migration/mti/
This page supplies contact information for our partners that have
a migration capability for Informix. One of these partners may be

Migrating image database in Informix 9.21 to Oracle 9i

I am going to be migrating an image database from Informix 9.21 to Oracle 9i and am needing to know
what Oracle9i has to offer as far as options in storing large media types - image, video, audio, etc...
Specifically, does Oracle have anything comparable to Informix' smart blobspace? Is it possible to migrate
image data from Informix to Oracle? I know the migration kits only are available up to Informix version 7.
What does interMedia offer?

Hi,
I was unable to reproduce your problem. I carried out the following steps in attempt to replicate the issue:
1. I launched the workbench, version 10.1.0.2, selecting the Oracle Lite "Default Repository".
2. Using the Oracle Enterprise Manager Console, I created a user "rtdb" with the password "rtdb" on my target Oracle 9i database.
3. I captured a test Informix database, generating its source and oracle models.
4. I then proceeded to migrate the database to Oracle and supplied my target Oracle9i database information in the "Migration Wizard, Step 1 of 4: Destination Database Details", supplying rtdb/rtdb as the username/password.
5. My test database migrated with no such error messages reported.
If you carried out the migration steps as I have outlined above, and are still experiencing issues with a "Failed to connect" error, I would contact support.
Regards,
Hilary

Migrating from Informix 9.4 to Oracle 9.2

Hi
I need to migrate a database from Informix 9.4 to Oracle 9.2.
There are a third-part application that must be migrated that always run in Oracle databases in others customers.
I have a script (supplied for the third) to create the objects in Oracle (+- 1200 tables that will be created only with PKs to improve performance).
My question is: Can I use the migration workbench only to load the data (45 GB)? If no, what can I do to minimize the work?

Hello,
Yes this is possible. You need to capture your source Informix database and map it to the Oracle Model using the Migration Workbench. Then you can generate the data unload scripts and SQL*Loader scripts to get the data our of your source database and into the destination Oracle database. For more information on how to do this, please see Chapters 4, 5 and 6 in the Oracle Migration Workbench User's Guide. You can find this document on the OTN Web site at:
http://download.oracle.com/docs/html/B15857_01/toc.htm

Format issue after Oracle Reports conversion

Hi all:
I am an intermediate Oracle Reports user and am evaluating teh use of BI Publisher as a replacement. Since I have a large number of reports, some of which are fairly complex, I wish to take advantage of the conversion tool.
The report in this issue has no user parameters. The Data Model is a "Data Template" type as generated from the conversion routine. The connection used was as the schema owner.
I can View the report, but the formatting is completely wrong and the charts are no longer in the report.
What do I need to do to fix this?
Any help appreaciated,
Gary

Hi Gary
The converter does not handle charts at the moment. You will need to re-create those in the template.
Need a bit more info on 'the formatting is completely wrong' to be able to comment further.
Regards
Tim

OMWB schema prefix (MS SQL Server to Oracle database conversion)

I made automatical conversion + some manual changes (pipelined functions) to migrate MS SQL 2000 database to Oracle 9i. Still one issue remains which requires lot of manual conversion : Names of the tables in views after automatic conversion doesn't contain schema prefix and it doesn't compile on destination database.
My question is: Is there any way to add schema prefix to table names in views automatically during migration process ?

Hi Marcin,
See my post in the OMWB forum
Thanks

Need 'Onstat -a ' of Informix equivalent command in Oracle

Hello Team,
I am searching for an option to dump all the Oracle Configuraiton like Initialization parameters, Dynamic information of Oracle Server.
Basically i am trying to find an command equivalent to 'Onstat -a' command of Informix, This command dumps all the cofiguration and runtime information of Informix server.
Any information on this would be higly appreciated.
Regards
Satish KB

Too bad your Oracle installation doesn't have a version number. <g> In Oracle version matters. For example in 11gR1 and above:
SQL> CREATE PFILE='c:\temp\spfileorabase.ora' FROM MEMORY;solves the problem instantly.
In 10g you can
CREATE PFILE='c:\temp\initorabase.ora' FROM SPFILE='SPFILEORABASE.ORA';
but it will not show hidden parameters that can be written in the 11g version.

Migrating informix row type to Oracle 8i

I have ascii files of an informix database and was using the SQL
Loader to import these files into Oracle8i. Everything works
fine except for tables with row types.
In the Informix ascii files, I have columns containing a set of
values. eg {x,y,z}. How do I get the Oracle SQL loader to import
these row type columns into corresponding object types in my
Oracle 8i database?
Any information or case studies on this would be desired as
well. I already looked and the Oracle 8i Utilities documentation
doesn't have a case study for loading object types.

you may want to look into using Oracle's Migration Workbench that will take your Access database and then translate it to an XML file from which it then generates the DDL and SQL*Loader scripts for you (which you can always modify before running).
Hope this helps.

Oracle timezone conversion

I have a requirment in which the database server time is being changed to GMT but one of the database users needs to store its data in CST or CDT as the case may be depending on daylight savings .I am thinking of writing a function which returns depending on date value passed on to it whether it is CST or CDT (depending on the day of the year ) and thiS function would be called from a before insert trigger for the tables so that the date data being passed on GMT time is converted back to CST or CDT before storing and stored as such then .Is this the best approach ,does oracle have a system function for this ? NEW_TIME is the function that I am aware of for timezone conversion however it doesnt take into consideration if it is CST or CDT .Thanks

What is the datatype - date, timestamp, timestamp with timezone?
There are ways of converting the date which includes daylight savings time considerations;
SQL> select sessiontimezone from dual
SESSIONTIMEZONE
-08:00
1 row selected.
SQL> create table t(ts timestamp)
Table created.
SQL> insert into t values(to_timestamp('01-jun-2007 12:00:00', 'dd-mon-yyyy hh24:mi:ss'))
1 row created.
SQL> insert into t values(to_timestamp('01-dec-2007 12:00:00', 'dd-mon-yyyy hh24:mi:ss'))
1 row created.
SQL> SELECT ts,
   ts AT TIME ZONE 'UTC' utz,
   ts AT TIME ZONE 'Canada/Central' ctz
FROM t
TS                         UTZ                               CTZ
2007-06-01 12:00:00,000000 2007-06-01 20:00:00,000000 +00:00 2007-06-01 15:00:00,000000 -05:00
