Oracle to Informix migration

Hi All,
I want to migrate an oracle project to informix. Can you please let me know a solution? If any tool fro that,please let me know.
Thanks,
Manikandan

Try this - http://www.ibm.com/developerworks/data/downloads/migration/mtk/
I'd recommend the latest version of IDS - with each release of v11 there's been more and more compatibility with Oracle, esp. stored procedures, sql extensions and the like.

Runnig forms in oracle 10g after migrating them from oracle 6i

Guyz ....i have developed forms in oracle 6i and when i presented them to the my manager he says that he wants them to be web based.....arghhhh.!!!!!! shud have told me at the beginning itself....anyways i downloaded the forms 10g from oracle website and migrates my forms from 6i to 10g ....
1.The forms are getting compiled and i can run them on my laptop.. i wanna noe whats the procedure to run them on other system .....the port number is 8889
I mean running them on a web on some other LP or system.???
2.And my 2nd problem is that ...The records are not being saved in 10g as in 6i. I created the forms in 6i using the data block wizard and set the block accordingly as told by u people in this forum

Look at the existing formsweb.cfg configuration file located in your <DEVSUITE_HOME>/forms/server folder. It allows you to create different sections to start your Forms applications.
For instance, if you create a application_1 section, give this name in your URL.

Oracle 10g XE migrate from 32bit to 64bit becomes slower

Oracle 10g XE migrate from 32bit to 64bit becomes slower
Currently we have a database using Oracle 10g XE R2
(Oracle Database 10g Express Edition Release 10.2.0.1.0)
on a linux 32bit server.
And recently we did migrate it to another 64bit linux server.
But found after migration is it running slower at 64bit server (~ 25% slower)
1. We would wonder any tuning is required on 64bit server?
Besides, as I know Oracle XE only using single core CPU for processing.
On 32bit linux the CPU is Intel(R) Xeon(R) CPU E31235 @ 3.20GHz
On 64bit linux the CPU is Intel(R) Xeon(R) CPU E5-2470 v2 @ 2.40GHz
2. Would the CPU clock speed on a single core also made the 64bit Oracle slower?
Thanks a lot.

32 or 64 bit normally won't cause much performance difference as long as you can't use > 4GB RAM
Please note that XE can use only 1 core and 1GB memory.
According to benchmarks, Single Thread Rating of the 2 CPU really differ by around 25%. Quite consistent with your observation.
Of course, IO (i.e., disk) speed is also an important factor.

Oracle SQL Developer vs Oracle SQL Developer Migration Workbench

Gurus,
Can anybody let me know what's the difference between Oracle SQL Developer vs Oracle SQL Developer Migration Workbench tools.
I am in the process of Migrating MS-Access Application to APEX. So the example says me to use Oracle SQL Developer Migration Workbench. Is this part of Oracle SQL Developer? If yes, I know SQL Developer is free.
If not is Oracle SQL Developer Migration Workbench if free?
Thanks and Regards

Thank Oracle ;)
(well, it's the least they can do after you paid big $$$ for the database)
Regards,
K.

Oracle length semantics migration documention

Due to the oracle documention to migrate length semantics:
To convert an existing schema and its associated data from byte semantics and a single-byte character set to character semantics and a multibyte character set, such as UTF-8, you need only follow these steps: [The following steps have been corrected since the magazine was printed.]
1. Export the schema.
2. Issue an ALTER SYSTEM SET NLS_LENGTH_SEMANTICS=CHAR SCOPE=BOTH command on the target database.
3. Stop and restart the instance so that the parameter change takes effect.
4. Drop the original schema.
5. Recreate the original schema and its tables (you can use import's show=Y option to get the CREATE TABLE statements). Columns in the recreated tables will use character semantics, because that's now the default.
6. Import the schema into the target database using the IGNORE=Y import option.
What is the meaning of the terms target and original?
Suppose there is a (source) database with length semantics byte. If a (target) database
is to be created as a clone of the (source) database, except for the length semantic char, does one have to migrate the (source) database first?
Or rather, why is it not possible to
1. Export the data from the source database with length semantic byte,
2. Create a target database with length semantics char,
3. Import the data from the source database?)

This documentation is, unfortunately, poorly written.
If you want to migrate data from one database to another, with both databases having different character sets, you can avoid some data expansion issues, if you migrate to character set semantics at the same time.
You cannot just export data, and import it into a character semantics database, because export/import preserves original semantics of the exported tables.
Note: there is actually no such thing as a character semantics database. Character semantics is a column/variable property. The "character semantics database" is a confusing, though commonly used, term that actually means an instance which has NLS_LENGTH_SEMANTICS set to CHAR in its initialization file. The only significant meaning of this parameter is to be the default for session-level NLS_LENGTH_SEMANTICS. It is used for sessions that do not set this parameter explictly (through environment variable or ALTER SESSION). The session-level parameter is significant for CREATE TABLE/PROCEDURE/FUNCTION/PACKAGE [BODY] statements and tells the default for column and variable declarations that do not specify BYTE or CHAR explicitly.
To migrate semantics of an original schema you need to create a script that will contain all CREATE statements needed to recreate this schema (at least CREATE {TYPE | TABLE | MATERIALIZED VIEW | PROCEDURE | FUNCTION | PACKAGE [BODY]}). Then, you can just add the ALTER SESSION SET NLS_LENGTH_SEMANTICS=CHAR after any CONNECT command in this script. You can than run the script in the target database. How you create the script is irrelevant. You can use any reverse-engineering tool available (e.g. SHOW=Y option of import, DBMS_METADATA package, etc.)
After you pre-create the schema with the new semantics, you can import the data from the original (source) database with IGNORE=Y. The original semantics saved in the export file will be ignored for pre-created objects.
Note: PL/SQL may need manual corrections to migrate to character semantics. For example, SUBSTRB used to trim values before assignment may need to be replaced with SUBSTR.

Oracle Application Hardware Migration using Acronis

Hi,
I’m an Oracle Applications DBA and would really appreciate some other DBA input on the following question.
I have a customer that uses Acronis to backup,restore and image Oracle Applications. Their current instance (11.5.6) is running on really old kit. As a test the windows guys have restored oracle Apps onto a brand new server and started the services. This has worked, which is to be expected (that’s what Acronis does).
My question is “Does Oracle support this method of hardware migration using Acronis”. My understanding is that for hw migration either autoconfig or export+import were the only Supported options.
I know that 11.5.6 is unsupported and come to mention it so is their OS and the fact that they use images as clones. This aside I would be interested in other opinions on weather Acronis is strictly for restoring/imaging a duff system or in fact weather it would be supported by Oracle for Hardware migration. ( With some reasoning please).
I have checked metalink with only one hit (643276.992) but this does not directly answer my question
Thanks in advance to anyone who can reply to this.
Cheers
James

Yes you will be able to do that (migrate/upgrade your 10g Forms & Reports applications to 11g Forms & Reports) and deploy on Oracle Fusion Middleware 11g.
Note that FMW 11g release having Forms & Reports is not yet out. I am not sure about the exact time frame but it is expected to be out sometime this calendar year.
Thanks

Where can I find oracle.toplink.tools.migration.TopLinkCmpMigrator?

Hi All
I am trying to find this class so I can start the toplink workbench - any ideas where I can get it ? its not in the toplink.jar as mentioned in the Oracle documentation
Thanks

From the documentation, it says you have to have
<TOPLINK_HOME>/jlib/cmpmigrator.jar
on the classpath, which is where the oracle.toplink.tools.migration.TopLinkCMPMigrator class can be found.
This is from the 10.1.3 docs at:

Problem while migrating from Sybase to Oracle using Quick Migrate

Hi,
For SQL Developer version 2.1, while migrating from sybase to oracle, Using Quick migrate, during data move step, for the rows having ''(Blank) values in TEXT data type in SYBASE, which is convertd to CLOB in Oracle, the migration for that table terminates at that row.
However, NULL values in Sybase TEXT data type are successfully inserted in Oracle CLOB.
How can we overcome this?

reproduced and see exception in console, bug logged.

Surely all you need to do is set CLUSTER_DATABASE=FALSE, and start the instance from a non-RAC Oracle home. Then tidy up the cluster registry: use the srvctl utility to remove the RAC database, and add a non-RAC database. All done in ten minutes.

Informix 7.x to Oracle 9i Data migration

Hi All,
I'm in the process of migrating the data from Informix 7.X databse to Oracle 9i. I need to migrate data from selected columns and selected tables only from the informix schema.The data migration deals with Huge volumes[ Around 50GB ] of data.
I need some help regarding
1. I'm thinking to use Informix Unload Option for data unloading and SQL * loader for loading the data into the database. Is there any other better way.
2. how to deal with the memory issues during migration process.
Regards
Gaurav

Hi,
Thanks a ton for the prompt response.
I'm elploring the usage of Migration Workbench for the migration.But yet don't know the correct way to use it.
I need some inputs and material to refer from this end.
Apart from that Regarding memory :
As I'm dealing with 50GB of data
1) I want to foresee any problems which i might encounter during the migration process.
2) Any oracle specific parameters I need to setup to rule out any memory related migration failures.
3) How can i do the migration in the quickest way?
Kindly do the needful.
