OWB Freezes at ORACLE Model creation.

I am in the process of migrating an ACCESS database to ORACLE. I followed the following steps:
1. Create a new ACCESS database and import the database that I want to migrate to the new database.
2. Compacting the new database as per document instruction.
3. Some columns in the database tables have binary definitions.
4. I changed these definitions to "text". Because ACCESS has not a BLOB or RAW definition.
5. Then I created the XML file with the migration_exporter.
6. Then I edited the XML file changing the text definitions of these particular files to ORACLE's "RAW" definitions.
7. Then I create the source model.
8. Then I create the ORACLE model.
9. During this creation the OMW get stuck at the fourth table it attempts to convert.
Please find below an output of Oracle Migration Workbench build 20041207 log file.

Hello,
You shouldn't be making any edits to the generated XML file, as is stated at the top of the file

I would suggest that you attempt to migrate your database as is, without changing definitions as you specified in point 4. Once the XML file has been generated, don't edit it. Load the file into the Migration Workbench and then follow the wizard through to generate the Source Model and Oracle Model.
I hope this helps.

Jocelyn

any idea to solve this error?

Also,
Can you tell me if any of your columns have more than 2000 characters?
SQL Server CHAR and VARCHAR columns can store up to 8000 characters, while Oracle CHAR stores up to 2000, VARCHAR2 stores up to 4000.
I think, You have CHAR columns greater than 2000, and if you have to map them either to VARCHAR2 perform the following steps:
* Go to Tools ->Options->Data Type Mappings
* Change the char to varchar2
Try using CLOB if you really have large character data since it has more limitations than VARCHAR2 (you will not be able to use CLOB in ORDER BY e.g.)
Thank you.

Creation of Oracle model hanging MS SQL 7- 8.1.6

Had a question answered yesterday which has got me almost there, for which thank you. Creating the Oracle model now maps almost all the objects in my SQL Server database (apart from a few roles, triggers and stored procedures), up to the point where the log window shows:
[Timestamp] Mapping Roles mapped: 7, Roles NOT Mapped: 3
[Timestamp] Mapping Mapping User Privileges
[Timestamp] Mapping mapped user privilege :
[Timestamp] Mapping mapped user privilege :
[Timestamp] Mapping mapped user privilege :
The process then hangs (it's been 21 hours now). Any ideas?
Scott Doughty

Your topic title, "Creation of Oracle model hanging MS SQL 7->8.1.6", caught my eye, but our situations aren't exact.
Workbench is hanging on me during the Oracle Model creation when it gets to "Mapping tables". I also waited about 24 hours without any results.
Do you have any insight to my problem?

Unable to Create Oracle Model When Migrating from access 2000 to Oracle

Hi ,
I am migrating an access 2000 Database to Oracle 9i using Oracle Migration Workbench .
I was sucessful in creation of Source Model ,but when I try to create the Oracle Data Model - Oracle Workbench
HAngs . In short the Oracle Model creation log screen hangs .
If any body has faced any similar please help me out .
Please suggest a work around for this problem .
Thanks in Advance
Arun

Arun,
Can you provide a reproducible test case so that we can confirm the behavior here and log a bug? More detail can be found in the log/Error.log in case there is a java exception that is being thrown.

Mapping in VC Model creation

Hi GLM,
Can you guide in VC model creation for mapping the data between SD_DOC to the SALESDOCUMENT field. Actually i am not getting
If not already displayed, open the Configure Element task panel and click the select line to the Inputport of Sales orderGetstatus. As you can see in the table at the bottom of the task panel, the SALESDOCUMENT field of the Salesorder Getstatus data service must receive data from the table. To map the data, assign @SD_DOC to the SALESDOCUMENT field, by clicking on the fx column and choosing it from the drop-down list (you will need to scroll down in the list).

got it.

How do i change column names in oracle model?

Hi,
I am performing a migration from SQL SERVER 7.0 to Oracle 8.1.7.
I have tables that have tables in SQL SERVER with column names
that are "TYPE" and "BODY".(These are generally TEXT datatype
columns that need to be converted to LONG in Oracle.We need
these to be LONG datatype in Oracle because of an application we
are using. LOBS cannot be allowed)
The migration utility renames these columns as "TYPE_"
and "BODY_" and creates the tables in the Oracle Database.
I need to have these tables in Oracle with the same column names
viz. "TYPE" and "BODY" .
I can create new tables in Oracle with the column names "TYPE"
and "BODY" but cannot change the options in the migration
workbench for this.
Is there any option or any workaround I can use to change the
column names in the Oracle model?or set the options so that the
Oracle model tables donot modify these column names?
Thanks in advance for all the help.
Mandar

The words 'TYPE' and 'BODY' are reserved Oracle words. Its best
to go along with what the workbench has suggested. If you have
to keep the original names of the columns trying wrapping double
quotes around them after the data migration is complete. This
may cause a case sensitivity or referential problem later on
though.

Tables are not coming to oracle model from sqlserver 2000 while using OMWB

Hi,
I am using oracle migration workbench to migrate SQL Server 2000 to oracle 9i. When �capture source database and create the oracle model� is run. only tablespace and users coming to Oracle model from sql server. Table are not coming. These table are owned by dbo in sql server and
All other users in the database has full privilege on this tables. Do I need to some setup to get this tables
In oracle model.
Thanks
Harish

Try the following
|| This script sets the "dbo" to have the "sa" login.
|| NOTE: Server settings for the SQL Server instance must be set to
||"Allow modifications to be made directly to the system catalogs".
|| This is found under Server Setttings tab for server properties.
UPDATE sysusers
SET sid = (SELECT sid FROM master..sysxlogins WHERE name = 'sa')
WHERE name = 'dbo'

Issue with Engineer Multidimensional Model from Oracle Model

Here is the scenario:
1. Created logical star schema model including a dimension with nested subtypes (SuperTypeEntity1 -> Subtype 1 -> Nested Subtype 2)
2. Forward engineer to Relational model using Single Table implementation
3. Create Oracle 11g physical model definitions for the star
4. Define dimension, levels, and hierarchy in physiclal model
5. Create new multidimensional model, right click menu and execute "Engineer from Oracle Model"
Result:
Model and diagram built with correct dimension, levels, level attributes, hierarchy
Problem: The entity that the dimension levels are related to is the subtype entity that appears first alphabetically! What it should do is be related to the SuperTypeEntity since I used the Single Table implementation (IMO). I can manually change the property to pick the SuperType but then it loses the assignments for the Level Key and the Descriptive Attributes (which were defined in the physcial miodel) so I have to manually repopulate those properties.
Associated problem: Since I tend to do things incrementally (define a few dimensions at a time), everytime I re-run the engineering utility, it resets the dimension back to the wrong subtype everytime. (I like the fact that I can rebuild the multidimensional model iteratively to incorporate changes, but in this case it would be nice to "lock in" my manual changes).
My only work around at this point is to either only run the engineering utility once (which is pretty impractical) or temporarily prefix my super type entity with an "A" so it always comes up first in the list until I am done with all my iterations.

Hi Kent,
dimensional model is not well suited to use entity hierarchies.
I can manually change the property to pick the SuperType but then it loses the assignments for the Level Key and the Descriptive Attributes (which were defined in the physcial miodel) so I have to manually repopulate those properties.It seems all your key and descriptive attributes are in SuperTypeEntity1 (the root of hierarchy). How to proceed if some attributes (key +descriptive) are in subtypes, should SuperType be set as level entity again?

Cannot create Oracle model MS SQL 7 - Oracle 8.1.6

Have MS SQL Server 7.0 and Oracle 8.1.6 running on same NT server. The SQL Server 7.0 Source Model is created with no problems - I can see each table and its owner (always dbo). When creating the Oracle model the tables from the MASTER database are loaded OK but when the user tables start every one fails. Error messages such as:
OracleModelImpl_insertObjInfo() java.sql.SQLException: ORA-01400: cannot insert NULL into... [I cannot see to the end of this line]
tbl_Batch_Prints: Table. Owner name is NULL. Check that SQL Server 7.0 MASTER database is correctly rec... [that's all i can see]
EXCEPTION: SQLServer7SourceModelMap.mapTables(): tbl_Batch_Prints, oracle.mtg.migration.MigrationS... [end of visible error message]
Where do I start to get this working?
Thanks, Scott Doughty

Very helpful! "exec sp_changedbowner 'sa'" did the trick. Almost... I can now start generating the Oracle model and just about everything gets mapped apart from some roles, triggers and stored procedures until the log window reads:
[Timestamp] Mapping Roles mapped: 7, Roles NOT Mapped: 3
[Timestamp] Mapping Mapping User Privileges
[Timestamp] Mapping mapped user privilege :
[Timestamp] Mapping mapped user privilege :
[Timestamp] Mapping mapped user privilege :
and then the screen hangs. It's been a few hours now and NT is showing no activity on any of the Oracle processes. Do I just need to be more patient, or has something gone wrong?

Anyone know anything about transistor model creation?

Although it was rather difficult, I've managed to get what may be half decent parameters into a 2n3055 model I'm trying to build. (I can never find the famous ".cir" model for anything.) The main place where I had zilch was input capacitance. So, since I started with the 2n2222's numbers, I just left them there.
I droped the "component" in a simple circuit, but clearly my pin mapping is hosed up. Hence, this leads to my first question.
I do not understand what "q%p %tB %tC %tE %m" is or how it maps to my symbol (an NPN transistor). Does anyone out there have a clue?
And yes, before you say it to me, yes, yes, yes, I did do the tutorial that had me follow the bouncing ball and create a programmable gain amp being promoted by Texas Instruments. But what does it do for me in trying to build a well-known transistor's model??
Also, as I briefly mentioned before, does anyone out there know where this great repository of *.cir models is? One would think that as common as a 2n3055 is, there most certainly is a 2n3055.cir out there somewhere, but I haven't found it.
Incidentally, I've found these, but I haven't a clue as to how to make them work for me:

I guess what I'm asking is has anyone out there successfully taken a NON *.cir definition and created a fairly well working transistor model, and will that person please be so kind as to help me to understand how to do it for myself?
I swear NI/Multisim are shooting themselves in the foot by not making user requested Multisim models available for a fee. They'd make soooo much money. Moreover, by only offering a scant few models, maybe, just maybe, their starting software price might be affordable to, oh, most people who can't access corporate funding.
I swear I'll pay a flat fee of $20 to anyone who will sell me a working Multisim model for any discrete component when I need it. One of the biggest hurdles of Multisim is producing functioning models. There is a tremendous business opportunity in producing working Multisim models, and it is only a matter of time until some entrepreneur out there cashes in on it. If NI/Multisim doesn't have the brains to figure this out, I'll bet somebody else out there does. For I have yet to have a model from a manufacturer work in Multisim, much less painlessly be transferred into it. This 2n3055/2955 modelwas tried by me nearly a year ago, but I eventually had to give up. ...and yes, I contacted technical support. Oh boy was that a bad move! ...but that's a story for another time.

I am only going to make one comment and I will leave the rest to someone with more experience on the model creation end of things. I am interested in that as much as you are since I have tried and and just couldn't figure it out and finally gave up on it.
My comment is about the model making business as you describe it. There are companies out there that already provide this service. I do not know what prices they charge for their services, but a Google search will pop up quite of few of them. A person would have to check on pricing and all the rest of the details concerning this, but they are out there.
I want to add that Multisim used to have a partnership with Edaparts.com to supply model information and footprints for free. When Edaparts became a portion of Partsminer.com this freebie ended and they now charge a subscription fee for this service. That really fudged things up in my opinion. Anyway, I thought I would let you know this if you didn't already and maybe you might be interested in checking it out.

Model creation versy slow...

Hi,
I am currently trying to use the Migration Workbench with an Informix DB.
I successfully managed to capture the model (offline), this was quite slow, but now that I have started creating the Oracle model, it seems to be taking forever. Indeed, for some tables, it takes up to 45 min to create the model. On average, it takes a minute or so, but with all those that take 45, it looks like it's never going to finish! The thing is, those tables aren't what I would call complex...
The target repository is an Oracle 8.1.7 hosted on a Win2K server that pings in less than 10ms.
Has anyone got an idea as to what is going on?
Thanks.
Regards,
Phil

Workbench hang's while are creating oracle model of informix BD

Hi,
we are testing to migrate informix 9.40 to Oracle 10g and when the migration workbench is Creating Oracle Model it is hang while it is treating one foreing key.
The Foreing key in informix is:
alter table "dtmpub00".we_docpalabras add constraint (foreign
key (codi) references "dtmpub00".we_palabras constraint "dtmpub00".fk_ref_21_15211);
The columns codi in the two tables are of type informix integer.
In the BD are others seemed foreings keys that workbench seems that to migrated correctly.
In the error.log file appears the following error message:

This looks like a bug. Can you raise a bug with Oracle support, so we can build an appropriate test case to reproduce and fix within development.

This is a known problem. It appears that you may be trying to map a non supported relationship. The OMWB does not support relationships based on queries, only queries based on tables are supported. To get around you hanging problem remove the non supported query and regenerate the xml file. Now try a capture and mapping phase. Hope this helps you get around your problem.

Appreciate feed back
Thanks.

Periyaswamy,
You will need to log a support request to get development to investigate further. We may need a dump of your Workbench repository to narrow down the issue.

Error when parsing SQLServer triggers tot Oracle Model

After capturing the SQLServer database into the Oracle Migration Work Bench repository (omwb) I have migrated the SQLServer sourccode to the Oracle Model (also in the
omwb repository). But...
when migrating SQLServer sourcecode to Oracle9i database some of the triggers are not migrated into the Oracle Model: triggers like :
----------->
create trigger dbo.tr_nev_del_audittable
on event_spare_memofield
instead of delete
as
begin
<-----------
are not migrated.
Can someone tell me why?
I am only getting the message:
Error occured on line 9:
oracle.mtg.sqlserver2k.parser.ParseException: Parse error at line 9, column 10. Encountered: of

Hi there,
I'm sure this is still a bug, bug you should change or comment out the offending lines and reparse the triggers. This way, you will get it into the oracle model and can start finsihing off the migration.
