Title: Multiple OLS policy on a single table
Post by Pete Finnigan on Jan 13^th, 2008, 7:40pm

I have created an OLS policy and successfully implemented it on my five tables. Then I created one more OLS policy and tried to implement it on one of the five tables in addition to other policy. Second policy was also successfully created and applied to the table but when I tried to update the rows for the second policy it is not letting me update the rows with the data labels. Also after applying the second policy to the table, users who were able to access the data previously are no longer able to access data anymore. When I had only one policy on the table my users were able to access the data as they were supposed to. What am I doing wrong? I am stuck. I searched the forum for this but could not find any similar problem…. Please help me debug. If anything else is required, please let me know and I will try to provide it.

Thanks in advance…

I am putting my script here so it is easier to see what is going on. Here is my script:

EXEC sa_sysdba.create_policy ('DBSEC','Row_LBL','ALL_CONTROL');
EXEC sa_components.create_level ('DBSEC', 1001,'Public','Public Level');
EXEC sa_components.create_level ('DBSEC', 2001,'Sensitive','Sensitive Level');

EXEC sa_components.create_group ('DBSEC', 40,'P','President');
EXEC sa_components.create_group ('DBSEC', 10,'MGR', 'Manager','P');

EXEC SA_POLICY_ADMIN.APPLY_TABLE_POLICY('DBSEC','db668a10','Department',NULL);

END;

UPDATE Employee SET ROW_LBL = CHAR_TO_LABEL('DBSEC','Confidential:HR,SLS:P') WHERE Emp_ID = 10475;

EXEC sa_sysdba.create_policy ('DOC','ROWLBL','ALL_CONTROL');
EXEC sa_components.create_level ('DOC', 4001,'Public','Public Level');
EXEC sa_components.create_level ('DOC', 5001,'Sensitive','Sensitive Level');
EXEC sa_components.create_level ('DOC', 6001,'Confidential','Confidential Level');
EXEC sa_components.create_compartment ('DOC', 502,'HR', 'Human Resource');

UPDATE Department SET ROWLBL = CHAR_TO_LABEL('DOC','Public:HR') WHERE Dpt_NO = 10;

Here is the output I get after applying second policy:

SQL> UPDATE Department SET ROWLBL = CHAR_TO_LABEL('DOC','Public:HR') WHERE Dpt_NO = 10;

0 rows updated.
