OWB Number of Column level restriction

Hi All,
I'm Pradeep....beginner in OWB 9i. I have one to one direct mapping with source and target table(delinquency mapping with buckets) same.The table is having 836 columns. I am trying to execute that but its running endlessly...
so my question to all..is
1) Do we have any "number of column restriction" ?
2) Are there any configuration apart for ROW based for performance tuning?
Thanks in advance!

Kindly reply....Desperately need the solution
thanks in advance

Column Level Subqueries

I am converting a MS SQL Server 7.0 database to Oracle 8i.
Currently, I run into problems to convert column-level subqueries
into Oracle. To give an example, I have the following SQL Server
7.0 query:
select col_a =
case
when ( a > 0 ) then 1
when ( a < 0 ) then -1
else 0
from table_a;
How do I convert it into Oracle? I tried to use DECODE and it
didn't work in this case. Any other alternative? Please help.
Thanks.

It works! Thanks a lot. I just wish the documentation could have
provided examples like that.

Oracle Virtual Private Database (VPD), Column Level Security

Hello,
About Oracle Virtual Private Database (VPD), is it possible to set a Column Level Security without setting a Row Level Security (without using any predicate)?
Thanks,
Herve.

Thanks, Zoran.
A colleague shared with me a link containing a function without returning a predicate (in using SYS_CONTEXT function to skip row restriction).

Column Level Security Using VPD under oracle 11g

Hi
I am using an example from Oracle Database 10g: Advance Security -- Virtual Private Databases
1. The Application Context -- that sets the session environment for the use is ok.
2. The Logon Trigger that executes the above is ok. It had been tested.
3. The Security Policy that returns a predicate after checking the output of the Application Context is ok.
4. The security policy applied to the STOCK_TRX table is ok.
5. Select and Insert from the database work.
However, after dropping both the insert and select policy, I am having problem getting a select policy to work with column-level VPD. I will get the ORA-28104 -- input value for statement type is not valid and ORA-06512 at SYS.DBMS_RLS line 20. See code below
begin
DBMS_RLS.ADD_POLICY
('PRACTICE', 'STOCK_TRX', 'STOCK_TRX_SELECT_POLICY', 'PRACTICE', 'SECURITY_PACKAGE.STOCK_TRX_SELECT_SECURITY', 'PRICE');
end;
Note:
PRICE is the sec_relevant_cols
STOCK_TRX is the table
Can you please help.
Thx

The syntax for row level security is not the same for columns level security. All the parameters to the DBMS_RLS.ADD_Policy() function should be preceded by the type of the parameter for:
begin
DBMS_RLS.ADD_POLICy(object_schema=>PRACTICE, ... sec_relevant_cols=>'PRICE);
end;
I did not know this before. I thought they were there in the example for explanatory reasons. I decided to answer the question for myself because I know others have the same interpretation.

Q : Using column level VPD policies with Oracle Jdeveloper ADF BC ?

For one of our big customer, we already successfully developped a new java application using Oracle Jdeveloper with ADF, ADF BC and the Virtual Private Database (VPD) with row level policies.
Our customer has new business requirements that could be fullfilled using column level VPD policies.
Has someone already successfully (or not) developped a business application using column level VPD policies with ADF, ADF BC on Oracle 10g R2 database and OracleAS 10g (10.1.2) ?
Is it supported by Oracle ? what are the pitfalls, difficulties, problems you've met ?
Is it a viable solution and if not, why ?
Thanks in advance.

Tomas,
my 2 cent:
if you know how to get the info from the db during run time you should be able to overwrite the frameworks message bundle look to get the description from the db instead of from the resource bundle.
Or you load all descriptions from the db into a resource bundle and use the keys in the tooltip directly.

Granularity of change rules in CDC (using Oracle streams) at columns level.

Is it possible to implement granularity of change rules in CDC (using Oracle streams) at columns level.
E.g. table abc with columns a1, b1, c1 where c1 is some kind of auditing column. I want to use CDC on table abc but want to ignore changes on c1.
Is it possible? My other option is to split table abc into a child table that has the Primary key and c1 only but it needs additional table and joins.
Thanks
Shyam

The requirement can be implemented by a simple trigger.

Column Level VPD

Hello all,
Am I correct in thinking that if the parameters below are added to the policy, column masking will be invoked:
,sec_relevant_cols => 'sensitive_column_name'
,sec_relevant_cols_opt => DBMS_RLS.ALL_ROWS
As 'sensitive_column_name' has been marked as securty relevant, is the value always returned as NULL or can I return the actual value for appropriate users?
Thanks,
Rhys David

By making use of sec_relevant_cols_opt => DBMS_RLS.ALL_ROWS, all rows will get displayed. However, sensitive column values will be returned as NULL.
If a query references a sensitive column, then the default action of column-level Oracle Virtual Private Database restricts the number of rows returned. With column-masking behavior, all rows get displayed, even those that reference sensitive columns. However, the sensitive columns display as NULL values. To enable column-masking, set the sec_relevant_cols_opt parameter of the DBMS_RLS.ADD_POLICY procedure.
Coming to your second point:
Rhys David wrote:
As 'sensitive_column_name' has been marked as securty relevant, is the value always returned as NULL or can I return the actual value for appropriate users?Actual values will be displayed for the appropriate users(as implemented in your policy function) for all the other users who are not supposed to have access to the sensitive column NULL will be displayed.

AA

VPD Update policy at column level

Hi,
I have a table abc and I have applied a policy for update. Now the user who has no access is unable to update the table abc. Can I just restrict the user from updating a specific column ( user_id column in the table abc), rather than restricting the user from updating all columns?
Thanks.

hi,
You can use sec_relevant_cols parameter of the DBMS_RLS.ADD_POLICY procedure
begin
dbms_rls.add_policy (
object_schema => 'SCOTT',
object_name => 'EMP',
policy_name => 'VPD_TEST_POLICY',
function_schema => 'SCOTT',
policy_function => 'TEST_VPD',
statement_types => 'select, insert, update, delete',
sec_relevant_cols => 'sal,comm');
end;
you can see this doc
http://www.in-oracle.com/Oracle-DBA/DBA-I/vpd-virtual-private-database.php
or
You can also use views to enforce column-level security, showing only which columns in a table may be updated. For example, assume that you must design roles based a table where only managers may view or update the salary column of the employee table (column restriction).
1 - You can grant the end-user access to only those columns you wish to update:
grant update (col1, col2) on mytab to fred;
2 - You might create a view with only those columns that you want to allow updates, the table appears to the end-user as-if it contains only those columns. By granting access only to that view (and not the base table), you can effectively implement column-level security and restrict which columns in a table may be changed.

Columns to rows in oracle 10g

Hi,
I need the output from columns to rows in oracle 10g.

Row and Column Level Select Permission

Hello Friends,
I am using Oracle Oracle9i Enterprise Edition Release 9.2.0.1.0 and Windows XP. I have two questions. How to set :
1. Row Level Select Permission?
2.Column Level Select Permission?
1. I have a table having 100 records in it. I don’t want to allow all the user to see them; means, if user1, user2 and user3 are going to select * from mytable then only they can get all the rows; while other users (including sys) should not able to get all rows, they should be capable of from 11th record.
Though it can be managed by using another table, but I am just finding the other solution.
2. Likewise, if I don’t want to allow to fetch all the columns; suppose column4 is having confidential info and only be visible by user1,user2 and user3 only, not by any othr user; what should I do?
Please guide and help me.
Regards

You would need to use Virtual Private Database (VPD)/ row level security (RLS) to apply row-level security policies to the table. The DBMS_RLS package is used for this
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_rls.htm#sthref6168
Unfortunately, column-level security wasn't available in 9.2. You would need to upgrade to Oracle 10g to get that functionality. Before that, you would have to create views that selected appropriate subsets of columns and grant permissions on those views to different users.

Will Performance degrade due to Column Level Security

Hi All,
I have report with 40 Columns, of which more than 20 columns are restricted to many users on the Dashboards.
This security is controlled by assigning permissions to those columns in RPD presentation Layer.
And setting the PROJECT_INACCESSIBLE_COLUMNS_AS_NULL to YES in NQSConfig.ini
Will the performance of reports degrade due to this type of design.
Is there any solid evidence?
Thanks
Kaushik

Hi,
I dont see any performance hinderance because of the column level security.
But remember in the pivot table you can still see the column without values. And its a bug. Would serve good for table views.
Hope this helped/ answered

How to restrict the EBS end users to run only two same reports at a time?

Hi,
We are using EBS 12.0.6 and database 10.2.0.3.
Is it possible to restrict the end business users to run only two reports at a time?
OR
Is it possible to restrict the end business users to run only two same reports at a time?
Thanks.

Is it possible to restrict the end business users to run only two same reports at a time?It is not possible.
You can either make the report "incompatible" to itself (this means only one user in your company can run it at a time)
Or not make it incompatible. (That means any user can run it any number of times)
Incompatibility is a way of specifying which requests cannot be run under which circumstances.
See http://download.oracle.com/docs/cd/A60725_05/html/comnls/us/fnd/incomp.htm
You can use Hussain's suggestion to use Concurrent: Active Request Limit profile. You can set this profile value at each user level. But if you decide to set it at global level, remember to keep it a higher value for sysadmin kind of users that run scheduled jobs.
Hope this helps,
Sandeep Gandhi

Column level versus row level security in SAP BI

This is a question. Sorry about the terminology clarification but it really does get to a question. Thanks for your patience and help.
There is some confusing terminology among BI users so let me explain terms. The terms appear to have some currency in the BOBJ world.
Row level security = the ability to control access to some data based on the values of a characteristic. Only the data authorized will be selected.
Column level security = the ability to exclude certain characteristics from display by any user.
In SAP BI row level security is managed by analysis authorizations (RSECADMIN).
To the extent of my experience (and I am unable to test it for about a month) column level security can only be managed by authorization object S_RS_IOBJ excluding the infoobject to be controlled with the sub-object DATA).
However my experience is that any query that reads an infoprovider that contains that infoobject will fail. It won't exclude and present to the user all the other infoobjects (i.e. columns).
Is this really so and if so is there any mechanism that can exclude columns without forcing the developer to either design an infoprovider or multicube that excludes the infoobject?
Edited by: Corwin Slack on Dec 14, 2009 2:07 PM

Two things
1. I would prefer not to have to rely on developers to implement a restriction in a query. Then I have to police every query.
2. I am not certain that the authorization isn't checked anyway because the query accesses the cube. (Sorry no test environment available until mid January)
My preference is that any queries that contain this authorization object just bypass the displaying the characteristic. My frecollection to date is that this isn't what happens. The query fails entirely.
