I am New To ODI 11g, i have to transport data from one Database(Oracle) to another Database(Oracle), for this the table in source was already imported in the source model, i am trying to setup Target database's meta data in ODI 11g and i have done all the steps right when i try to reverse engineer this new model which i created nothing happens. I am stuck with this problem at work since there is no error so i cannot think of any reason why meta data is not being imported
I would like to clarify this, the target table which i am trying to import is accessed from ODI with the super user
Any help would be appreciated.
Could you check that the schema used to connect to the Dataserver where the target table is located actually got the privileges to access the target table?
If not, grant select and insert (and maybe update, delete depending on the IKM you use) on that table.
I faced the same issue and resolved it by providing read access to the schema ODI is using to reverse engineer.
As I was using standalone installation, ODI studio log had the below information:
[2015-01-17T19:10:21.979+05:30] [] [NOTIFICATION] [] [] [tid: 2374]
[ecid: 0000Kfs7s20Fg4WFLzvH8A1KiWkx00000d,0] New data source:
[HR/*******#jdbc:oracle:thin:#//localhost:1521/pdb1]
HR schema was the first schema I reverse engineered, and it was being used as default user to read other schemas.
Try checking the agent logs to see what user is being used and provide it the privileges on all other schema's.
Althoug I dont know how to tell ODI to use a particular user to access database while reverse engineering. It would be great if some one gives some insight on it.
Probably on masking of reverse engineering you are missing character: %

I am using Oracle apex 5,oracle database 12c
I have successfully configured oracle apex 5 with oracle DB 12c.
I have created authentication scheme using database table,that Authentication scheme worked successfully.
But my requirement is - Each user has to be connect to its own schema
(eg.user1 = HR; user2 = SCOTT)
with in same application.
Shortly, application must run on multiple schemas at run time.
But I am not able to get that,I have tried below stuff -
current parsing schema is 'SCOTT' try to change it using -
apex_application.g_flow_owner := 'HR'; --Failed
ALTER SESSION SET CURRENT_SCHEMA = 'HR'; --Failed
I don't understand what to do,Please some body help me for solving it.
I think you are on the right track, the apex_application.g_flow_owner := 'HR'; command should do the trick but you have to place it in shared components > security > security attributes> database session > Initialization PL/SQL Code
Edit: First of all having a schema for each user that logs into the application i do not think is the best approach. Just think that every modification has to be done to all the schemas. I suggest you take a look at Virtual Private Database (VPD) it can help you to control data access.
But if you still want to try changing the schema i think you can do it like this. Create two processes for each page in your application; one at On Load Before Header and one at On Submit. This process should contain something like this:
BEGIN
if :APP_USER='SCOTT' THEN
apex_application.g_flow_owner := 'SCOTT';
ELSE
apex_application.g_flow_owner := 'HR';
END IF
END;
Like this when Scott loads a page the schema is changed to SCOTT and he sees data from his schema. When HR loads a page the schema is changed to HR and he sees his data. Same thing when they submit a page; the schema first changes and then you do the other operations.
This second idea is not bullet proof and that's why i advise you to rethink what you want to do.
Edit2: In component view simply click on the plus sign on "Processes" to add a process and in the wizard select "On Submit - Before Computations and Validations" for the Point option.
It seems it is only possible to create document-type databases via the HTTP-api. The documentation omit's information about whether the database will be created as a graph or a documentdatabase, but when creating a vertext, i get the error:
Super-class V not exists
...which, as i understand, means that the database is a document-type.
Is there any way around this? The /command/ action makes it pretty easy for me to do what I want from C#, if I could only generate a graph-database via HTTP-api...
Is there any way to create a graph-database through the HTTP-API?
Alternatively: Is there another way to create a graph-database from c#? I've tried creating a database via the console, but here i get IllegalArgumentException:
Error: java.lang.IllegalArgumentException: Storage type 'plocal' is different by storage type in URL
..which i cannot find any explenation for
Any help is much appreciated :)
I managed to have that using POST http://localhost:2480/database/<db name>/plocal/graph
I did found it experimentally. Did not found that in documentation which is a bit strange.
Tested on version 2.1.7
I got the same error message when I typed in the following command:
create database REMOTE:localhost/petshop root aaaa plocal document
Solution:
I had to write it in lower case:
create database remote:localhost/petshop root aaaa plocal document
We have an Firebird database for a (very crappy) application, and the app's front end, but nothing in between (i.e. no source code).
There is a field in the database that is stored as -2086008209 but in the front-end represents as 63997.
Examples:
Database Front-End
758038959 44093
1532056691 61409
28401112 65866
-712038758 40712
936488434 43872
-688079579 48567
1796491935 39437
1178382500 30006
1419373703 66069
1996421588 48454
890825339 46313
-820234748 45206
What kind of storage is this? The aim for us here is to access the application's back-end data and bypass the front-end GUI alltogether, so I need to know how to decode this field in order to get appropriate values from it. It is stored as a int in FireBird (I don't know if FireBird has signed/unsigned ints, but this is showing as signed when we select it).
This is the definition of the field:
It is not, as far as I can tell, de-normalised. The generator GEN_CONTACTS_ID has 66241 against it, which at a glance looks accurate.
I work on with an application that stores bitmaps in integers (just don't ask), if you express them in that form do you something useful or consistant
My impression is that the problem is in the front end. If what is stored in the DB is -2086008209, then what is stored in the DB is -2086008209. To understand better how the application is manipulating the data, try storing other numbers in the DB and see how they are displayed.
Did you come to this realization through logging SQL? If you havent, you may serve yourself well by using the Firebird Trace API to get that SQL: http://www.firebirdfaq.org/faq95/. An easier tool to parse the Trace API is this commercial product: http://www.upscene.com/products.fbtm.index.php.
I've used these tools and other techniques (triggers etc,.) to find what an application is using/changing in the Database.
Of course, if the SQL statement is select * from table, then these tools would not help much.
I really hope someone has some insight into this. Just to clarify what I'm talking about up front; when referring to Schema I mean the database object used for ownership separation, not the database create schema.
We use Sql Server Schema objects to group tables into wholes where each group belongs to an application. Each application also has it's own database login. I've just started introducing database roles in order to fully automate deployment to test and staging environment. We're using xSQL Object compare engine. A batch file is run each night to perform comparison and generate a script change file. This can then be applied to the target database along with code changes.
The issue I'm encountering is as folows. Consider the following database structure:
Database:
Security/Schemas:
Core
CoreRole (owner)
SchemaARole (select, delete, update)
SchemaBRole (select)
SchemaA
SchemaARole (owner)
SchemaB
SchemaBRole (owner)
Security/Roles/Database Roles:
CoreRole
core_login
SchemaARole
login_a
SchemaBRole
login_b
The set-up works perfectly well for the three applications that use these. The only problem is how to create / generate a script that creates schema -> role permissions? The owner role gets applied correctly. So for example, schema Core gets owner role CoreRole (as expected). However the SchemaARole and SchemaBRole do not get applied.
I wasn't able to find an option to turn this on within xSQL object nor does an option to script this from SQL Server management studio exist. Well, I can't find it at least.
Am I trying to do impossible? How does SQL Server manage this relationship then?
I just kicked up SQL Profiler & trapped what I think you scenario is. Try this:
GRANT SELECT ON [Core].[TestTable] TO [CoreRole]
GRANT DELETE ON [Core].[TestTable] TO [CoreRole]
GRANT UPDATE ON [Core].[TestTable] TO [CoreRole]
Dear all, Is there any tool available that can check all databases in a system by sending some sample data to the database to make sure that data transaction is occurring correctly. Moreover, the sample data should be invisible an inaccessible from the outside world. If you have any idea please help.
Update
Thank you for your answer. But I have some questions regarding your given answer.
Is the above solution is applicable to MySQL and SQLite?
If so, then where to open the database.txt file?
By the way, I am using WampServer2 for the system and my database is MySQL
1) create database.txt file and
change file type with name
database.udl
2) open the file
3) select tab provider
4) select Microsoft Ole Db Provider
for ODBC Drivers and press Next
5) write . or (local) in Use data
source name
6) select database name in (Enter the
initial catalog to use)
7) Test Connection
