SQL & PL/SQL :: Oracle Virtual Private Database Policy
Mar 31, 2012
I created policy as follow.
BEGIN
DBMS_RLS.ADD_POLICY (
object_schema => 'scott',
object_name => 'orders_tab',
policy_name => 'orders_policy',
function_schema => 'nisadmin_vpd',
policy_function => 'get_user_orders',
statement_types => 'select');
END;
/
After the creation of this policy for the table when I select the table Orders_tab then getting the below error.
ORA-00904: "ORA_ROWSCN": invalid identifier
When I dropped this policy then I can see the records of Order_tab table.

1)I have created a complex view, and created an instead of trigger on this view
example:
create or replace trigger tr_x instead of before update on test_view_name for each row
-------
2) I have created an update policy on this view
DBMS_RLS.ADD_POLICY (
object_schema := schema_name,
object_name := name of the view,
policy_name := ploicy name,
function_schema := func schema name,
policy_function := pkg_test.fn_get_where,
statement_types := 'UPDATE',
update_check := TRUE,
policy_type := dbms_rls.dynamic);
3) function pkg_test.fn_get_where, which is used in the policy function always return 1 = 2, so that update should fail.
4) Now I will issue an update statement on the view test_view_name
update test_view_name set test_col = 1;
but still it updates the records, though update policy returns the where cluse 1 = 2
same where clause for select policy works perfectly fine.

We are currently replacing all public database links with private db links in our prod environment. The requirement is
1) private db link name should be same as public
2) Need to create and test out private db links before we can drop public db links.
How can we test out private db links while public db links are still there with the same name?
when I execute SELECT * FROM DUAL@DBLINK from user who created this private db link, which db link it will be using- public or private?

We just got a new Dell R720 server that will host our Oracle DB. The server hasn't even been turned on yet but we know that the load on the server will be very low for a long time.
One of our problems is that we need to run a VERY important application. Since it is not very resource consuming compared to it's importance we chose to run it on a not so new Xeon 5110 1.60 GHz - 4GB RAM server. He said it's not a good idea and that we should buy a new server. (money is very low)
The software vendor suggested to virtualize our R720 server, host a vm running our database, and along with it other smaller machines like the one I described above. I suggested the use of Oracle VM, Oracle Linux for the database host and transforming the physical servers servers in VM with P2V.
Our IT Manager didn't like that, he said that it's not recommended to run a database on a virtual machine. But our software vendor said that many of their clients run their solution this way.

I have a Host system of windows 8, installed the Virtual Box Latest edition.The guest OS is the oracle Linux that came with the Pre-Built Developer VMs from Oracle.The VM is set to HOST ONLY network setting. Now, the thing is that i want to access the Oracle in the guest machine from my windows host machine.the guest OS shows the IP address as 192.168.56.101. I can ping the IP address from the HOST machine, but cannot connect theSQL developer to the oracle in the guest OS from the host machine. It keeps on saying the Network adapter cannot connect. do not say that install the oracle in window itself. I actually want to do the same on my macbook pro as that is my primary machine.

Host: Win7
Guest: Using Virtual PC on Win7, created a VM using XP-Mode. Installed Oracle and everything on it. I can connect to the Oracle from within the guest env using sqlplus. Listener is also running, checked with 'lsnrctl status"
Guest and Host can ping (network) each other. I installed the guest using the Microsoft Loopback Adapter. Disabled the firewall on the guest OS before the host ping could work.
So ping works both ways from guest to host and host to guest. tnsping from host fails says "no listener". When I did a "telnet 192.168.x.x 1521" from host it said could not open connection on port 1521.
How do you open port 1521 on the guest OS to traffic from the host OS?

When working against the Oracle 10G/11G RAC database it's important to have all the relevant entries in the etc/hosts file.
Thus, when running the following code against the database sometimes it finishes with "Ok!" and sometimes getting the error below:
CODEimport java.sql.*;
public class TestDBOracle {
public static void main(String[] args)
[Code].....
The reason is missing RAC-related entries in the etc/hosts.
When dealing with Oracle RAC it should be both entries for the public and for the virtual IPs of the nodes in the etc/hosts file.
CODEA.A.A.A NODEA
A.A.A.B NODEB
...
B.B.B.X NODEA-VIP
B.B.B.Y NODEB-VIP

------
CREATE TABLE alert_hist
(
alertky INTEGER NOT NULL,
alertcreatedttm TIMESTAMP(6) DEFAULT systimestamp NOT NULL,
alertcreatedt DATE GENERATED ALWAYS AS (To_date(Trunc("alertcreatedttm"))) VIRTUAL NOT NULL
When I do the import (IMPDP) it got failed with the following error.
. . imported "TESTSCHEMA"."VALART" 359.1 KB 4536 rows
ORA-31693: Table data object "TESTSCHEMA"."ALERT_HIST" failed to load/unload and is being skipped due to error:
ORA-39097: Data Pump job encountered unexpected error -1
After that I dropped the Virtual Not null column and recreated that column with Nullable.
DDL :
-----

alter table alert_hist add alertcreatedt DATE GENERATED ALWAYS AS (To_date(Trunc("alertcreatedttm"))) VIRTUAL;
After that I took the expdp and impdp , it went fine with out any issue.

I'm running Oracle 9i on AIX 5.2. I'm not using a recovery catalog, nor am I using media management software. I perform a full, online rman backup of the database and archived redo logs daily to disk, then use operating system commands to copy the backup to tape. There is only space on disk for two days' backups, so I need to have a retention policy of "redundancy = 1", and run a "delete obsolete" prior to the backup. The problem is that I don't want to subject the archived redo logs to this retention policy.
I have two physical standby databases connected by WAN to the primary site, and I might need archived redo logs that are a few days (or more) old in the event of a prolonged WAN outage. I've read about the "keep forever" option, but apparently it isn't available without using a recovery catalog. Is there any way to spare the archived redo logs from my retention policy?
Note: I want to "protect" the actual archived redo logs from the retention policy, not the backups of the archived redo logs.

How we can use RMAN backup to restore oracle database when the RMAN backup pushed to tape already and being a OLD backup ( before retention policy date).Just to elaborate a more.. Say my retention policy is 3 days. I want to restore from a old backup like 30 days old.So surely the requesting backup is behind retention date and has been pushed to tape.

I'm on a Windows server 2003 R2 64 bit, database is 11.1.0.7. From RMAN connected to the target and the catalog, this is a show all;
RMAN> show all;
RMAN configuration parameters for database with db_unique_name ORCL are:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 3 DAYS;
CONFIGURE BACKUP OPTIMIZATION OFF;
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'F:oracleadmin
[code]....
I'm running incremental backups, a level 0 on sunday and a level 1 the other days of the week, this is the ctl file:
LEVEL 0:
connect target /@ORCL
connect catalog rman/rmanpw@rmancat
RUN
{
[code]....
The level 0 does delete the archive logs (because of the delete input). Each backupset has two copies of the archive logs (which is what I want), and I expected the logs to be deleted after being backed up 2 days (each day is twice, 2 days = 4 times). But it's not deleting the logs, even after 6 runs.

CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE COMPRESSION ALGORITHM 'BASIC' AS OF RELEASE 'DEFAULT' OPTIMIZE FOR LOAD TRUE ; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY
I dont want to backup the STDBY DB but I want the ARC files to be removed when applied so my flash area does not fill up. Is there some command(rman or not) that can fire off this policy?

The "private strand flush not complete" is a "noise" error, and can be disregarded because it relates to internal cache redo file management.
However this "private strand flush cannot complete" error is sometimes accompanies by a hung database.
These are quotes from MR Burleson himself .
But can this be really ignored as it's also mentioned "hung database"

I'm making a function A that does many calls to procedures in an other package B. To make this function more readable, I'd like to specify synonyms for the procedures in B. I only need the synonyms inside this function, I don't want to make database synonyms.
For example:
Function get_all_employees return clob
is
v_emp clob;
begin
[Code]....
