I am trying to setup logon/logoff auditing for our databases which reside in 9i and 10G on sun solaris servers. I am asked to turn on auditing sending the audit data to syslog! How exactly do you do that?

Let us say I want to audit data updates, deletes on existing table EMP_TAB that has a few hundred thousands of records.I created a shadow table Emp_tab_audit and added few audit columns
Emp_tab (
Empno NUMBER NOT NULL,
Ename VARCHAR2(10),
Job VARCHAR2(9),
[code]...
I am mostly interested in UPDATES and DELETES but I decided to add INSERTS to have full history for each eomplyee in one table (audit schema) instead of querying two tables all the time (production table and audit table) to see the changes.
I created this AFTER INSERT, UPDATE, DELETE trigger.decided to copy the :NEW values for INSERT and UPDATE and :OLD values for DELETE. attached.
so when insert happens, the first audit row is created in EMP_TAB_AUDIT. update happens, the 2nd new row is created in EMP_TAB_AUDIT.
The problem I am facing is the old records that curently exist. If someone updates an old row I am copying the :NEW values so I won't have a copy of the :OLD values unless I create 2 ROWS (one for the old and one for the new).
Do you think I should copy all the hundreds of thousands of records to the AUDIT tables for this to work.
*******************************************************************
CREATE OR REPLACE TRIGGER TRG_EMP_AUDIT
AFTER INSERT OR DELETE OR UPDATE ON EMP_TAB
FOR EACH ROW DECLARE
v_operation VARCHAR2(10) := NULL;
[code]...

getting logon timestamp for our auditing process. In some website, it says to get the logon timestamp I have to select it from timestamp column of dba_audit_session but when I do this, some results has a logoff earlier than logon. Is timestamp column really the logon timestamp?
SELECT
returncode,
(logoff_time-timestamp) timeonline,
TO_CHAR(timestamp, 'DD-MON-YYYY HH24:MI:SS') LOGON_TIME,
TO_CHAR(logoff_time, 'DD-MON-YYYY HH24:MI:SS') LOGOFF_TIME,
action_name
FROM dba_audit_session;

Oracle Audit Vault 10.2.3.2 & Linux Red Hat 5 on a V.M. box
I'm new to the Audit Vault and am experiencing some issues. Right now my biggest question is how does A.V. deal with TNS issues (allowing the collectors to find remote target db's) when we do not add any tns entries to the local tnsnames file?
We've recently added more space and our sysadmins have moved all of our AV data to the new disk space and have supposedly updated pointers allowing us to continue seamlessly. However now my collectors won't start, they are complaining with message below. These had started previously before the space add.

In Oracle Database 11.2.0.2, to delete audit trails after the audit records have been inserted into Oracle Audit Vault, is it necessary to schedule Oracle Audit Vault jobs to clean up audit trails on a scheduled basis, or AV automatically cleans up audit trails after the audit records have been inserted into the Audit Vault? I know there is a DBMS_AUDIT_MGMT package, but in 11gR2, the deletion of audit trails isn't done automatically?

I am using 'Novell Sentinel Log Manager' to collect/fetch logs from my Oracle 11g R2.To enable auditing, first I did following:
login as sys, then
SQL> create user testuser identified by "testuser";
SQL> grant connect to testuser
SQL> grant dba to sharf
SQL> grant CREATE SESSION to testuser;
SQL> grant select on v_$session to testuser;
SQL> grant select on v_$version to testuser;
SQL> grant select on SYS.DBA_AUDIT_TRAIL to testuser;
SQL> grant select_catalog_role to testuser;
SQL> grant select any dictionary to testuser;
Now logon/logof of user 'testuser' are logged , as well as if testuser drops a table or creates a table, its also logged . but when 'testuser' insert a new record, this information does not logged ;( while I need to know exactly what was added SQL> insert into emp (empid, name, salary) values (10002, 'Ron', 6000)
likewise if 'testuser' modify/update an existing record it also does not logged.
SQL> update emp set salary=700 where empid=10001;
which sql statements I have to execute to start auditing 'insert' and 'update', so that I know what was added/inserted and exactly what was updated/ changed/modify by user 'testuser'.

I installed Audit Vault Server 12 (not install firewall) in a oracle linux vmware and activated an agent for Oracle 11g release 2 in windows 7 x64 vmware according to Oracle® Audit Vault and Database Firewall Installation Guide and Administrator’s Guide Release 12.1.0 as follows:
1) ALTER SYSTEM SET AUDIT_TRAIL=XML, EXTENDED SCOPE=SPFILE; Database restart
2) Register the Oracle Database Host Machine
3) Deploy Agent and Request Activation on the Host Machine
4) Create user accounts on the secured targets and set up Oracle AVDF user privileges on an Oracle Database secured target.
5) Register Secured Targets in the Audit Vault Server with user acount of stpe 4:jdbc:oracle:thin:@//IP:1521/orcl
6) Configure an Audit Trail in the Audit Vault Server : TABLE - sys.aud$ or DVSYS.audit_trail$, DIRECTORY - directory of audit trail xml saved.
I turned off firewall just in case.Administrator web page of AVDF showed only messages of "request completed" after configuring an audit trail in the Audit Vault Server.But, collection state was a red downward arrow, and even auditor web page showed same state.I couldn't show audit trails in the auditor web page.

I have to find all the 'failed log ins' through audit report. then it has to be uploaded to a table. The script, either in windows or unix should be reusable and can read files one by one.

Is there any way to enable the constraint with out validating for the existing information.
As We can accomplish the same functionality when we are adding the constraint for the first time.
Ex: alter table scott.emp add constraint fk_deptno foreign key(deptno) references scott.dept(deptno) enable novalidate
The above SQL statement will enable the constraint with out validating for the existing information. So there is possibility of data will be there only in the child table but not in the parent table for existing information.
But in the future it will not allow to do so,if the constraint is in ENABLE staus.So i am just trying to disable the constraint to insert only into child table & trying to enable it with NOVALIDATE option .
But the following exception is coming .
SQL> alter table scott.emp ENABLE constraint fk_deptno enable NOVALIDATE;
alter table scott.emp ENABLE constraint fk_deptno enable NOVALIDATE
ORA-00905: missing keyword
SQL> alter table scott.emp ENABLE constraint fk_deptno NOVALIDATE;
alter table scott.emp ENABLE constraint fk_deptno NOVALIDATE
ORA-00933: SQL command not properly ended
Instead of dropping & recreating the same constraint , is there any alternate way to do this ?

I developed a custom form upon which I developed a query find block to query the data on the main form. I have WHO columns in the table and referencing them in the main form. But Some reason when I query the data by pressing the find button on the query block it is retreiving the data properly, but record history is not enabling.
In the query find block I have 3 text fields, 1 check box and 2 date fields.

I have scheduled a ADHOC Oracle JOB in OEM to gather statistics for the database with 100% estimation during weekend. This JOB currently fails because of a batch Job that runs at the same time and drops few old partitions. This OEM job runs for 1 hour and fails because few partitions are getting dropped at the same time.
How i can enable this statistics JOB to skip/Ignore errors and to continue to run to gather complete statistics of the entire database. I have scheduled this job in OEM. how can i enable this SKIP/IGNORE errors for this job.

My requirement is as below,
I have one main form and there is one button when i click on it, another form should be opened which should display multi records with check box for each record.
I have implemented so far. When the new form is opened by default all the records should be checked. if user does not want some of them then it can be unchecked(This can done manually)..
I have put below code in when-new-block instance trigger
set_item_property('LOCKBOX_DETAILS.CB_SUBMIT', ENABLED, PROPERTY_TRUE);
Unable to load the block with all the records checkboxes checked.

I have a partioned table that has close to 2 billion rows and a PK of all columns. Becuase of time constrains my APP team wants the PK disabled while they pump into hundreds of thousands of rows with a batch process.
Now I am finding when I enable the PK its eating up close to close to 200GB of temp space.
Is there something I can do to reduce the amount of temp space being used?

OS: oel6.3 - 2.6.39-300.17.2.el6uek.x86_64
Grid and DB: 11.2.0.3.4
This is a two node Standard Edition cluster.
The node crashes upon restart of clusterware after following the instructions from note:751343.1 (RAC Support for RDS Over Infiniband) to enable RDS. The cluster is running fine using ipoib for the cluster_interconnect.
1) As the ORACLE_HOME/GI_HOME owner, stop all resources (database, listener, ASM etc) that's running from the home. When stopping database, use NORMAL or IMMEDIATE option.
2) As root, if relinking 11gR2 Grid Infrastructure (GI) home, unlock GI home: GI_HOME/crs/install/rootcrs.pl -unlock
3) As the ORACLE_HOME/GI_HOME owner, go to ORACLE_HOME/GI_HOME and cd to rdbms/lib
4) As the ORACLE_HOME/GI_HOME owner, issue "make -f ins_rdbms.mk ipc_rds ioracle"
5) As root, if relinking 11gR2 Grid Infrastructure (GI) home, lock GI home: GI_HOME/crs/install/rootcrs.pl -patch
Looks to abend when asm tries to start with the message below on the console. I have a service request open for this issue but
kernel BUG at net/rds/ib_send.c:547!
invalid opcode: 0000 [#1] SMP
