How to generate XSD from simple table (e.g. emp from scott/tiger)?

Please excuse the ignorance...
I've been trying to determine if there's a simple way (i.e. using a command in sqlplus or via a GUI wizard), to point to a simple table (such as the demo 'emp' table), and have Oracle then generate an XML Schema (XSD) file that contains the representation for that table, so that I can use that XSD file with various XML-based tools.
Any help is appreciated.
Thanks,
Mike

How to create hierarchy on bi7 by using dtp

how to create hierarchy on bi7 by using dtp

Hi Deba,
Procedure to create Hierarchies:
1.      In the Data Warehousing Workbench under Modeling, choose the InfoObject tree.
2.      If you have assigned the hierarchy basic characteristic to an InfoObject catalog, select the corresponding InfoObject catalog for an InfoArea.
If the hierarchy basic characteristic does not belong to an InfoObject catalog, choose the InfoArea Non-Assigned Nodes and the InfoObject Catalog Non-Assigned Characteristics.
3.      Select the characteristic for which you want to create a hierarchy and choose Create Hierarchy from the context menu. The Create Hierarchy dialog box appears. The InfoObject name appears by default.
4.      Enter a hierarchy name and description (short, medium, long). Other fields may be displayed, depending on which hierarchy properties were selected for the hierarchy basic characteristics
Fields used to enter the Validity (valid to, valid from) for the hierarchy property Total Hierarchy Time-Dependent
Fields used to specify the Hierarchy Version for the hierarchy property Hierarchies Version-Dependent.
5.      Confirm your entries. The Maintain Hierarchy screen appears. You can define the structure of a hierarchy here.
6.      To create a hierarchy node, you first need to choose an insertion mode: Insert as First Child or   Insert As Next Neighbor (see Hierarchy Editing Functions).
7.      Choose the type of node you want to create: Text Node, Characteristic Node, <Hierarchy Basic Characteristic Node> or Interval (see Hierarchy Nodes)
8.      Repeat this procedure until the hierarchy structure has been set. For more information, see Modeling Nodes and Leaves.
A hierarchy can contain 50,000-100,000 leaves at most. If your hierarchy is larger, you should insert a level that is used as a navigation attribute or preferably as a separate characteristic in the dimension table.
9.      You can use Level Maintenance and Hierarchy Attributes to set how the hierarchy is to be displayed and processed in reporting (see Level Maintenance and Hierarchy Attributes).
10.      Save the hierarchy.
11.      Activate the hierarchy. See Editing Hierarchies.

I really would like to know how to totally remove Yahoo toolbar from my Firefox browser as well as my computer. I don't like those special toolbars at all.

I really would like to know how to totally remove Yahoo toolbar from my Firefox browser as well as my computer. I don't like special toolbars at all. I find it irritating that you included one in the newest version of your browser. In the future I would hope you would leave this or any other out. Firefox used to be my favorite browser to use, now I am not going to want to use it because of the extra toolbar. Please tell me there is a way to remove this, not just hide it.

You can't move the Yahoo Toolbar from IE to Firefox, they are totally different "behind the scenes". However you can install it, [http://us.toolbar.yahoo.com/ http://us.toolbar.yahoo.com/] and I believe if you log in with your Yahoo account it will sync your data.

How Can I See How Many Total eMails are in My Inbox?

Hi,
My mail boxes on the left side of the window show how many emails have been unread, but I I want to see how many total are in each inbox. Is there a setting that I am missing to be able to see not only the unread, but also total emails?

Hi BDAqua
Thanks for the response. I am using a POP account. When I click on a mail box and goto Account Info I have three options:
1) Messages on server, nothing in there for display
2) Mailbox Behaviours where I get Notes diplay option, Sent mail option to delete or not, Junk nothing to do with display or Trash, when to delete, nothing on display.
3) Summary - no options here for any display.
Am I missing something?
Thanks

How to maintain Hierarchy?

Dear all,
We create a hierarchy on CM Account(InfoObject),Every month there ara some new records should be upload to it.
The problem is that after upload new records the hierarchy wouldn't maintain,so the report result is wrong.
I want to kown how to maintain hierarchy ?
Thanks.

Hi
When you are on the infoobject (characteristic only) right click -> Create/Maintain Hierarchy.
External hier. refers to the hier. you extract from external systems (e.g. Cost center hierarchy in R/3 sys.)
Internal hier., on the other hand, is the one you create in BW (thru Create Hier. selection). You maintain it manually.
Please find the Document wiht the Screen shots.

How to Create Hierarchy

Dear Experts!!!!!!!!!!
Can some one explain me in detail, how to create hierarchy.
both internal and external hierarchy,methodology,steps.................
Thanks in advance......

Suman.T

Explain the steps to load master data hierarchies from R/3 system.
A summary of the steps are as follows:
1) Goto Hierachy tab in infobject on to which your loading Hierachy data.
2) Select With Hierarchies.
3) Select Hierarchy Properties ( Time Dependent or not time depen..etc..)
4) Click on External Chars in Hierarchies, in that select the characterstics on which this Hierarchy is depending.
5) Then Create Infosource, assign Datasource.
6) Create Infopackage, to load Hierarchies.
7) Hierarchy section tab in Infoapackage select load Hierarchy and refersh the Available Hierarchies from OLTP, If it is Time dependent select time interval in update tab.
8) Then start the load.
If you want to load from Flat file, some what different way to do it.
It is normally done by the following:
Transferring the master datasources in RSA5 to RSA6 and then replicating the DS into BW and assignment of DS to Infosource and cretaion of Infopackage and load it into the master tables.
Generally, the control parameters for data transfer from a source system are maintained in extractor customizing. In extractor customizing, you can access the corresponding source system in the source system tree of the SAP BW Administrator Workbench by using the context menu.
To display or change the settings for data transfer at source system level, choose Business Information Warehouse --> General Settings --> Maintaining Control Parameters for Data Transfer.
Note: The values for the data transfer are not hard limitations. It depends on the DataSource if these limits can be followed.
In the SAP BW Scheduler, you can determine the control parameters for data transfer for individual DataSources. You can determine the size of the data packet, the number of parallel processes for data transfer and the frequency with which the status IDocs are sent, for every possible update method for a DataSource.
To do so, choose Scheduler --> DataSource --> Default Settings for Data transfer.
In this way you can, for example, update transaction data in larger data packets in the PSA. If you want to update master data in dialog mode, smaller packets ensure faster processing.

How to find the password of the scott

How to find the password of the scott
Any query please

Hi,
Its not possible to get the password back from the ORACLE as such.
Because its not that it saves the passwords as such encrypted.
Try to give same password for different users and check from DBA_USERS, most of the times you might get different encrypted passwords even though the base password is same - which shows the password is not encrypted as easy to decrypt...
Only thing you can do is reset the password when someone forgets it as DBA - but not find the old password.

Hi, this is mihir shah
I have just installed oracle9i
And I have a problem in opening the sql plus. It asks for user id and pass but when entered scott, tiger it always gives a tns error.
Could you tell me how to make a database & how to log on & how to make a new user id and password

It seem that you have problem with network connectivity to you database.
Check the listener status and the configuration of the files: tnsnames.ora & listener.ora
In all cases you must specified the error.
