Trying to use Oracle Label Security with a XMLType

Hi everybody.
I'm trying to apply some of the Oracle Label Security functionalities to a table created from the annotations of a XML Schema
(Below I show part of this XML Schema:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xdb="http://xmlns.oracle.com/xdb"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified"

<xs:element name="FILE_INFO" xdb:SQLType="FILE_INFO" xdb:defaultTable="TABLE_FILE_INFO">
<xs:complexType>
<xs:choice>
<xs:element name="FILE_INFO_DICOM"
type="FILE_INFO_DICOM_TYPE" />
<xs:element name="FILE_INFO_ANALYZE"

</xs:choice>
</xs:complexType>

<xs:element name="Value" type="xs:string" minOccurs="0" maxOccurs="1"/>
</xs:all>
</xs:complexType>
................etc
I've created a security policy that I have tested on relational tables (not based on any object type) and works correctly.
BEGIN
SA_POLICY_ADMIN.APPLY_TABLE_POLICY(policy_name => 'policy1',
schema_name => 'oe',
table_name => 'TABLE_FILE_INFO',
table_options => 'LABEL_DEFAULT, READ_CONTROL, WRITE_CONTROL',
label_function => NULL,
predicate => NULL);
END;
When I try to apply this policy to the XMLSchema-created table (TABLE_FILE_INFO) I get next error messages:
ORA-22856: cannot add columns to object tables
ORA-00604 error occurred at recursive SQL level 1
ORA-12445: cannot change HIDDEN property of column.
ORA-06512: in "LBACSYS.LBAC_POLICY_ADMIN", line 257
ORA-06512: in line 2
I suppose that the main problem is that the apply_plicy procedure is trying to add an extra column to a table created from a defined type.
So my questions are: It's that true? Is it possible to apply a policy to the content of XML documents, I mean, if I want to restrict that some users see some subset of a XML document based on a specific policy, is there anything similar to Oracle Label security for XML? (as defined with the annotations in the XML Schema, some elements will be mapped to rows of a XMLType-based table when a XML document is inserted into the XMLDB repository (marked to follow the previous XML Schema of course)
Hope someone can help to solve my doubts...
Thanks,
Marcos.

Have you ever answered this question? If not, have you tried to use the "HIDE" property on your table_options?

How to implement Oracle Label Security with Oracle8.1.5 database

I want some fields in some tables which could not be even viwed by DBA..
I am working on Oracle Server 8.1.5
If possible it should be in the same database,same schema but different schema may also work..
Please help

I don't think this is going to be possible.
When you register a crawler, you have to declare it as one of three types: Public, Identity-based or Attribute-based.
The database crawler is registered as attribute-based, and therefore must be used with a suitable authorization manager.
I guess in theory you could create a new authorization manager class which queries active directory to get the appropriate security attributes for a user (corresponding to the security attributes crawled from the database), but I suspect it might be easier to figure out a way to copy AD attributes into a database table (perhaps updating the table once a day via a nightly crawl of AD) and then use the standard database authorization manager.

Using non-alphabetical symbols in Oracle Label Security API

I decide to use Oracle Label Security Release 9.0.1 , but I have some problems in realization . When I try to use function sa_policy_admin.apply_table_policy with
following parameters:
sa_policy_admin.apply_table_policy(
POLICY_NAME => 'policy1',
SCHEMA_NAME => 'domain1\user1',
TABLE_NAME => 'table1'
I receive messages :
ORA-00604: error occurred at recursive SQL level 1
ORA-00911: invalid character
ORA-00911: invalid character
ORA-06512: at "LBACSYS.LBAC_POLICY_ADMIN", line 251
ORA-06512: at line 2
Tell me please , may be there are any limitations on parameter SCHEMA_NAME in function ,
because this function can't understand symbol "\".
Note 1: It is obligatory to use symbol "\" in schema_name ,
because I have to connect to DB as external user (user of Windows 2000 Server).
Note 2: ORA-00911 invalid character
Cause: Special characters are valid only in certain places. If special characters other than $, _, and # are used in a name and the name is not enclosed in double quotation marks ("), this message will be issued. One exception to this rule is for database names; in this case, double quotes are stripped out and ignored.
Action: Remove the invalid character from the statement or encl[i]Long postings are being truncated to ~1 kB at this time.

Yes I have with 10gr3
It can be made to work but perhaps not in the way you want (per user?). Your label security will need to have policies based on something.
I did a proof of concept using Security Group column as the 'label'. Then applied VPD policies based on which network the request came from (1 DB rac node in each network).
In my case I wanted to show ALL content to a secure network but a subset of content to the lower security network. For this use case it is ideal.
It worked flawlessly...not supported though
Apparently OLS is on roadmap or UCM (WCC) so ask Oracle and see if you can find out if it is slated for any particular release yet.

OID-Integrated Label Security with HTMLDB?

Hi,
I've followed the how-to document to integrate Oracle Label Security with Oracle Internet Directory.(http://www.oracle.com/technology/deploy/security/database-security/howtos/ols_oid-how-to.html).
I've successfully created a label security policy for the HR.LOCATIONS table. I would like that same policy to be effective on any query regions in an HTMLDB application.
I created a test application in HTMLDB, and changed the authentication scheme to be LDAP. It uses Oracle Internet Directory to authenticate the users, and this works successfully.
However, when I login with an OID user that has been assigned to use the policy, I get no rows returned.
What is a good way to integrate my label security policy with my htmldb applicaton so that it works within HTMLDB and outside of HTMLDB?
I saw the technote to use VPD, but when I tried this, it caused my label security policy to stop working. I somehow made it conflict...(http://www.oracle.com/technology/pub/notes/technote_htmldb_vpd.html)
I guess I'm just not sure what the VPD function should look like after I've already created a Label Security Policy.
I basically want it to look at the APP_USER and then apply the policy appropriately.
Thanks,
Nora

Scott,
It still worked in SQLPLUS when I typed 'set role none' first.
The way I granted PROFILE_ACCESS was through a label security command:
SQL> exec sa_user_admin.set_user_privs('senspolicy','parse_schema','FULL,PROFILE_ACCESS');
It seems like this is the only way..
It just seems strange that it works in SQLPLUS. I'm trying to figure out what other permissions I need for HTMLDB.
Thanks again,
Nora

Workaround for using Oracle JDBC extension with WLS pooling

Reading the newsgroup I saw that many of us encountered the problems
with ClassCastException when tried to use Oracle JDBC extension
with WLS pooling. I also had.
In this case BEA recommends to use dangerous
method getVendorConnection() which exposes
the physical connection object to your code.
Yes it's really dangerous because of unsafe usage may breaks
WLS pooled connection(s).
Moreover, this practice will make your JDBC code
unportable (your JDBC code in addition to Oracle dependence
became Weblogic dependent):
void doSmth() {
Connection con = ...;
Connection vCon = ((WLConnection)con).getVendorConnection();
// + mess of usage con in one places and vCon in others
// (where Oracle extensions are needed)
// !Don't forget to don't close vCon!
Sux.
I found the workaround.
Introduction
============
Yes the real cause of ClassCastException is that
in depth of Oracle driver the casting
to class oracle.jdbc.driver.OracleConnection
(not to interface oracle.jdbc.OracleConnection)
is performed.
Someone can say that this is bug or pure desing.
Weblogic pooled connection provide dynamic
implementation for all public interfaces
which real physical (wrapped) connection object implements.
Great feature!
But I guess that all interface methods implemented
by simple call-delegation to physical (wrapped) connection object.
In case of oracle.jdbc.OracleConnection interface
this approach doesn't work for at least one its method:
public OracleConnection unwrap()
WLS pooled connection shoudn't implement this method by
delegation to physical connection object BUT should
return physical connection object itself!
// Wrong implementation of unwrap()
// delegation is used
public OracleConnection unwrap() {
return physicalConnection.unwrap();
// Right implementation of unwrap()
// physical connection returned
public OracleConnection unwrap() {
return physicalConnection;
Workaround
==========
1. Develop your own OracleConnection wrapper class:
import oracle.jdbc.OracleConnection;
import weblogic.jdbc.extensions.WLConnection;
public class MyOracleConnectionImpl implements OracleConnection {
private OracleConnection con;
public MyOracleConnectionImpl(OracleConnection connection)
throws SQLException
this.con = connection;
public OracleConnection unwrap() {
return (OracleConnection)
((WLConnection)con).getVendorConnection();
/* Implement all other methods by delegation to con object */
2. Don't get Connections directly from DataSource --
develop your own simple (may be static) utility
class which retrives Connections from dataSource
and returns them wrapped into your MyOracleConnectionImpl
to your code from some method:
puclic abstract class MyConnectionSource {
public static Connection getConnection() {
Connection con = // get it from DataSource
return new MyOracleConnectionImpl((OracleConnection)con);
3. Add attribute RemoveInfectedConnectionsEnabled="false"
to definition of your JDBCConnectionPool within config.xml
You may do it because of you `safely` use vendorConnection --
you don't expose it to application code.
4. Enjoy the Oracle JDBC extensions in your code!
Example:
Connection con = MyConnectionSource.getConnection;
ArrayDescriptor add =
ArrayDescriptor.createDescriptor("your_type", con);
Hope it helps to someone.

Eugene Voytitsky

Hello Eugene Voytitsky,
Thanks Eugene Voytitsky for your idea
I have tried the solution suggested by You, but it did not work.
It still throws ClassCastException.
I am sorry for posting the whole code of two classes below.

How to install "Oracle Label Security" on "Oracle Developers Day" VM?

Hello,
I downloaded and started the "Oracle Developers Day" pre-built virtual machine using VirtualBox.
I need to install Oracle Label Security in order to make some tests with it. So:
1) Do we have the installation folder of Oracle Enterprise Edition somewhere on the VM?
2) If not, how can I install OLS? Do I have to use shared folder to mount the installation media? How can I mount the installation folder, which I downloaded and stored on the host machine? Could you, please, provide step-by-step example?
Thank you in advance.

Trying to use the JSSE library with Jrocket 7.0

Hi All,
I HAC who is trying to use the JSSE library with Jrocket 7.0.
Sometimes the socket works and sometimes it does not. It throws the below
exception,

the line of code causing the stack trace is:
Socket socket =
javax.net.ssl.SSLSocketFactory.getDefault().createSocket(HOST, PORT);
He has added the following line to his jre/lib/security/java.security file:
security.provider.3=com.sun.net.ssl.internal.ssl.Provider
and he has added the JSSE jar files to the jre/lib/ext directory.
The problem occurs when SSL is enabled in the config.xml file (e.g. <SSL
Enabled="true" ...>). It does NOT occur when SSL is disabled.
When SSL is disabled, the following code shows all three providers as
defined in the java.security file. If SSL is enabled then he only sees the
default 2 implementation and NOT the one he added above.
java.security.Provider[] a = java.security.Security.getProviders();
for (int i=0; i < a.length; i++)
System.out.println("name: " + a.getName());
System.out.println("ver: " + a[i].getVersion());
System.out.println("info: " + a[i].getInfo());
The problem is that client does not want to use WebLogic specific classes to
create an SSL socket. As well he do NOT wish to dynamically register the
SunJSSE provider. Since this setup works when SSL is disabled in WebLogic he
believes he has configured everything properly.
It appears to me that WebLogic is removing the JSSE as a security provider
if SSL is enabled.
Is it the expected behaviour? and Is it possible to statically register the
JSSE provider in the jre/lib/security/java.security file ?
Any pointers will be appreciated,
Thanks in advance,
Rubesh

Hi Howard, just trawling through the Labview TE issues as I myself have started to work on a similar issue. I have now infact upgraded the Labview Test Executive to work in 7.1 ok (both development and Runtime).
Using XP I had no issues upgrading in the development environment - creating the run-time version was not as easy but manged to do so with help from the Application Builder. I have also tested the SQL function (as i log to Oracle) and a basic audio test using a DSA4551 - again both seem to be upgraded with no issues.

Advance Replication and Oracle Label Security

Has anyone been able to configure both Advance Replication and Oracle Label Security to work together?

This is currently not supported in Streams. I have an enhancement request in with Oracle for this functionality. This won't be seen in 11g R2 either.
Has anyone done Label Security with Advance Replication?

Yes you can forward requests from your own apache to the iAS. This can be done using mod_proxy. Some hints about how to do this are availlable on this forum.
mod_oc4j is not a standard apache module, and therefore is not availlable when you download apache. There is no apparent reason to use mod_oc4j on a "regular" webserver (unless you want to build your own iAS). Also there might be some licenseing issues with using mod_oc4j module on a standard apache.
You can encrypt data that is passed from a random Apache to you iAS.

Enabling Oracle Label Security on 9.2.0.7 database

Hi there,
I have installed the option Oracle Label Security and patched it to 9.2.0.7. I have then run the script $ORAHOME\rdbms\admin\catols.sql . Which re-starts the database.
But when I run the below example I get the below error.
SQL> CONNECT lbacsys/lbacsys
Connected.
SQL> EXECUTE SA_SYSDBA.CREATE_POLICY( -
'FACILITY','FACLAB','READ_CONTROL,CHECK_CONTROL,LABEL_DEFAULT,HIDE');
BEGIN SA_SYSDBA.CREATE_POLICY( 'FACILITY','FACLAB','READ_CONTROL,CHECK_CONTROL,LABEL_DEFAULT,HIDE'); END;
ERROR at line 1:
ORA-00439: feature not enabled: Oracle Label Security
ORA-06512: at "LBACSYS.LBAC_SYSDBA", line 107
ORA-06512: at "LBACSYS.SA_SYSDBA", line 43
ORA-06512: at line 1
I have also noticed that in the v$option view shows the
PARAMETER VALUE
Oracle Label Security FALSE
I have compared the number of objects to metalink article 171155.1 How to Install / Deinstall Oracle Label Security and all the objects seem to be in the schema.
Also I check the version and saw below.
SQL> conn dba/
Connected.
SQL> COL comp_name FORMAT A32
SQL> COL version FORMAT A16
SQL> SELECT
2 comp_id
3 ,comp_name
4 ,version
5 FROM dba_registry
6 where comp_id='OLS';
COMP_ID COMP_NAME VERSION
OLS Oracle Label Security 9.2.0.7.0
1 rows selected.
SQL>
Anyone know how I can enable Oracle Label Security is that it works?
TIA
Ed

I still have some old 9.2.0.8 databases running on both HP-UX and AIX and have clients on 10.2g which doesn't manifest any problem .

Advantages and Disadvantages of Using Oracle 7 Client with Oracle 9 Server

Hello,
I was wondering what are the advanatges of using Oracle 7 client with Oracle 9 Server versus using Oracle 9 Client with Oracle 9 server.

Some years ago I used 7.3 Client with 9i DB, and I don't remember of particular problems, but I'm speaking of Sql*Plus only. Are there specific problems ?
Of course the best thing is to install one 9i Client (did you already do it ?) : if there are same problems, then that's not compatibility issue.
And what are advantages of using 9 Client with 9 server other than 7 is no longer supported.You're sure you won't have compatibility problems.
If you have access to Metalink have a look at [url http://metalink.oracle.com/metalink/plsql/ml2_documents.showFrameDocument?p_database_id=NOTE&p_id=207303.1]Note 207303.1

Is it possible to use Oracle Forms 10g with Oracle 10g Lite Database?

Hi All,
We are in process of migrating our forms from 6i to 10g environment.
We have two kinds of applications, one set run on general Oracle 11g database and the other set of forms run at the client machine using Oracle lite database.
We dont have any problem with Forms 6i to connect to Lite database as it allows to connect through ODBC:DSN names. When we try to connect to a lite database (10gR3) from Forms 10g through ODBC/DSN, it's not allowing and throwing the below error.
ORA-03121 : no interface driver connected - function not performed
Can someone tell me if there is something wrong in our approach? Also advise how to use Oracle Lite database with Forms 10G.
Sincerely,
Praveen Manthena

Hi,
I have experience with 6i with lite database 10g. There are two version of lite database one is multi language support and other one in english. There lang problem in connectivity with multi language 10g lite database. I done connectivity with single language connectivity of 6i with 10g lite database. You should try this one with forms 10g.

How is iTunes telling you it is unlocked? Did you go through an unlock procedure with your cell company and then Restore it in iTunes?
