OLS: error ORA-07445

Question

Hi Community
I am writing because I was informed of your knowledge in Label Segurity and I have a problem with a customer in Venezuela. The customer is Liberty Mutual Insurance Caracas.
The architecture was implemented where Label Security has a RAC Database 10g (1) and a DB PHYSICAL STANDBY mode (2) implemented with Dataguard).
When the policies were implemented on the production database (1) everything worked perfectly, and Dataguard replied installing Label Segurity on stand by without any problems.
When you run a SELECT on one of the tables in the DB PHYSICAL STANDBY (2) which have implemented policies, presents the error ORA-07445.
Then when you start the Policy Manager on the DB PHYSICAL STANDBY (2) the same error appeared. ORA-07445
But if we SELECT with the user owner of the object or the user SYS SELECT runs without errors.
Ask. In an architecture like this, Label Security can not be installed? Or does not work?

Hi Mark,
the example script was created only for a more simple reproducibility test. The original SQL statement that causes the error is:
SELECT SE0010, SE0030, SE0040, SE0050, SE0060, SE0070, SE0005, (SELECT COUNT(*) FROM G1SEGN01 WHERE SE0010 = SE1010) AS ALLEGATICOUNT
FROM G1SEGN00
WHERE SE0060 = 'INSERTED' AND (SELECT COUNT(*) FROM G1PATT00 WHERE EXISTSNODE(SE0080,PA0020)=1) > 0 AND SE0070 = 0
and the tables structure are
Table: G1SEGN00
Nome Nullo? Tipo
SE0005 NUMBER(15)
SE0010 NOT NULL VARCHAR2(30)
SE0020 NOT NULL VARCHAR2(100)
SE0030 NOT NULL VARCHAR2(25)
SE0040 NOT NULL VARCHAR2(255)
SE0050 NOT NULL DATE
SE0060 NOT NULL VARCHAR2(10)
SE0070 NOT NULL NUMBER(8)
SE0080 NOT NULL SYS.XMLTYPE
SE0090 VARCHAR2(100)
SE0065 VARCHAR2(1)
Table: G1SEGN01
Nome Nullo? Tipo
SE1005 NUMBER(15)
SE1010 NOT NULL VARCHAR2(30)
SE1020 NOT NULL DATE
SE1030 NOT NULL VARCHAR2(1000)
SE1040 NOT NULL VARCHAR2(2000)
Table: G1PATT00
Nome Nullo? Tipo
PA0005 NUMBER(15)
PA0010 NOT NULL NUMBER(8)
PA0015 NOT NULL NUMBER(5)
PA0020 NOT NULL VARCHAR2(1000)
PA0030 VARCHAR2(2000)
PA0040 NUMBER(3)
Clearly the field SE0080 contains an XML document and the field PA0020 contains an XPATH expression.
The SQL statement is executed from an .NET application (using c#)
Tell me if more lines of trace file could help.
Thanks again, bye.
