I am trying to track down the cause of some ORA-101017 errors that are occurring intermittently. We are running PeopleSoft and every so often (couple days) we see a burst of these errors in one of our application server log files. They are not specific to a particular server and only last about 5 minutes.
There do not appear to be any messages in any of the Oracle logs and the database is not recording any failed log in attempts. No passwords are being changed and/or account changes are being made.
I can think of is that there is some sort of connection limitation to the database which causes these errors to spawn when the maximum number of connections is reached.
My question is whether or not the ORA-01017 error could be inticatve of this type of problem and/or what might be going on.

I want to do something like this
-------------------------------------------------------------------------------------------------------
While Condition
LOOP
BEGIN
Insert into table1 values(......);
[Code]...
EXCEPTION
When OTHERS THEN <capture the error while inserting into an Error table>
END;
END LOOP;
-------------------------------------------------------------------------------------------------------
Now I want that If one of the insert statement within the loop fails (say table2) the exception should be captured and next insert statement (table3) should be executed.
How can I do this ? I guess I wont even need a loop

I have a set of 500 insert queries which i need to execute. I have included exception handler to catch any errors encountered. I don't want the execution to halt when an exception is encountered, i want the next insert statement to be executed
I am pasting the sample code below
DECLARE
error_code NUMBER := SQLCODE;
error_msg VARCHAR2 (300) := SQLERRM;
BEGIN
INSERT statement 1
INSERT statement 2.....
....................
INSERT statement 500.....
commit;
EXCEPTION WHEN OTHERS THEN
IF (SQLCODE != 0) THEN
DBMS_OUTPUT.put_line(SQLERRM);
END IF;
END;
For example if insert statement 100 fails the exception should be caught and execution should pass to 101 statement.

For the following procedure if I send the existed employee number of emp table as input. The procedure is executing successfully. But if I send the employee number as input which does not exist in the emp table . The execution block does not handling the exception.
I am getting the following error.
ORA-06502: PL/SQL: numeric or value error
ORA-06512: at "RAKULA.SP_TEST_EXCEPTION_BULK", line 8
ORA-06512: at line 7
If I use WHEN OTHERS exception then I am able to handle that exception. Why it's happening like this.
CREATE OR REPLACE PROCEDURE RAKULA.sp_test_exception_bulk(i_empno NUMBER)
IS
t type_test1;
BEGIN
SELECT deptno BULK COLLECT INTO t
FROM emp
WHERE empno=i_empno;
[code].......
how to handle that exception.
If I create the procedure without using
BULK COLLECT then I am able to handle that exception using WHEN NO_DATA_FOUND
In the following procedure I am able to handle the exception.
CREATE OR REPLACE PROCEDURE RAKULA.sp_test_exception(i_empno NUMBER,v_dept_no OUT NUMBER)
IS
BEGIN
SELECT deptno INTO v_dept_no FROM emp
WHERE empno=i_empno;
EXCEPTION
WHEN NO_DATA_FOUND THEN
dbms_output.put_line('employee number' ||i_empno|| 'does not exist');
END sp_test_exception;

Is it possible to insert a table in case of exceptions. For example, i have a function like this:
Create or replace Function test_function(p_Parameter_ID number) Return number is
l_Variable number;
Begin
Select output into l_Variable from test_table where id=p_Parameter_ID;
Exception when others then
Insert into exception_Table values('No Data Found', p_Parameter_ID);
return l_Variable;
End test_function;
In this function, if you notice, i wanted to populate an exception table for further analysis in case data is not found. The function gets compiled without any error in this case.However when i execute this and the Select query does not return any output for a particular parameter_ID, then the exception part fails. It gives me an error "cannot perform a DML operation inside a query".
Can't i write insert statements inside the exception section?

v_errorcode VARCHAR2(10);

PRAGMA Exception_Init(constr_violation,-2292);

Here, I have assigned values to the variables 'v_errorcode' and 'v_errormsg' directly inside the exception block so that I can use them in both exception types 'constr_violation' and 'others'. I am getting an error message like,

Is there a save exceptions clause or an equivalent for an Insert as select* statement ?
How do I trap the errors in the below statement -
INSERT INTO copy_emp
SELECT * FROM emp;
Is it an all or nothing scenario ?

I'm using Oracle 10gR2 (10.2.0.4.0) 64 bits.
I got many times oracle ORA-00494 error and the database went down but since 29th of july the database have not been killed.
The error message is below :
ORA-00494: mise en file d'attente [CF] d�tenue pendant trop longtemps ( (more than 900 seconds)) par inst 1, osid 176484
ORA-00028: votre session a �t� ferm�e
My database is used for datawarehouse of many terabytes.
Initially the redo log size was 500Mbytes and I've set it to 3Gbytes. The maximum log switch is after 5 minutes. I want log to be switched every 20 minutes or every 30 minutes.
To obtain the size of redo logs I've executed this query :
SQL> select OPTIMAL_LOGFILE_SIZE from v$instance_recovery;
OPTIMAL_LOGFILE_SIZE
--------------------
54763
53,5 Gbytes is it not very big as redo log size? What's the maximum size of redo log? To set very big redo log size what are the requirements? Which precautions should I take before? What are the risks? Are any other ways to change the log switch frequency?

I am using Oracle 11.2.1.0 version.I want to restrict archiving for some tables. I think NOLOGGING will solve this problem. Is there any option for restricting archiving.
For example, I have three tables called A, B and C. I want to archive only 2 tables A and B but not C.

I am trying to create materialized views based on a few tables in a logical standby database.
The target database (11g R2) where the MVs will be created is a stand-alone database.
The DB where the base tables reside is a logical standby database (11g R2).
The requirement is to do a "FAST REFRESH" of the Materialized Views.
My questions are :
1. Can I create MV logs in the logical standby DB?
2. If the answer to question no. 1 is "Yes", do I need to do anything different or configure the logical standby DB in a specific manner in order to create MV logs. From what I understand, the objects in the logical standby database are in a locked state.

Assuming you have a 9i database . where you have it enabled in archive mode , yet constantly deleting the archived redo logs , due to space constraints .
Will you be able to perform a full level 0 backup , and the following incremental backups , in the absence of the archived redo logs ? And are these incremental backups enough to recover the database or particular data files , to the point of the backup itself at least ?

Is there a way to automate deletion of applied archived logs after rollforward?
I'm thinking of crontab, and a script referring to the alert log to get the archived log filename.
Setup:

DB: Oracle 10g 10.2.0.4.0 (mounted)

I'm currently working on a project in which I do not have permissions to access the Server where the database is installed and configure.Because of company policies, I do not have Admin Rights over Oracle, but I do have an account that can make Selects to DBA_USER_PRIVS for instance.
I would like to know if there is any way to access the database logs to know if there was any kind of problem within the database, because one of my Schemas misteriously went clean (all tables, sequences, triggers, ... vanished)

I have two Oracle 10.2.0.4 databases, on two SUN M5000 (Solaris 5.10). One is primary (EXP1), the other is the standby (EXPBKP). Both SID is 'EXP'. If I do a manual recover (after I sync'ed primary archive logs from primary to standby), it works. If I do a manual log switch, logs are shipped AND applied on the standby. But after a while, I can see some errors on primary alert log , and logs are not shipped anymore :
CODE Errors in file /applications/oracle/admin/EXP/bdump/exp_arc2_1277.trc:
ORA-03135: connection lost contact

I'm an Oracle novice and from what I've read so far, it seems that you should be able to do rollbacks and data recovery using the redo logs. I'm having a difficulty understanding the need for the undo tablespace.

My supervisor wants to remove all the archivelogs since it was just a test for 1 year the DB is not actually YET been used. Problem is they want it to be used as soon as possible w/o recreating again the database and just removing some data on tables and removed archive logs. how to safely removed the existing archived logs and create a full backup with archived fresh to sequence 1.

I have an environment in which backup is performed of Oracle 10/11 databases with the use of RMAN and Tivoli Storage Manager (Data Protection for Oracle).There are several databases and for every one there is a daily full backup and hourly archive logs backup.
Sometimes when full db backup takes longer (up to 4 hours) archive logs backups are missed - as TSM node cannot perform two backups at a time. I would like not to have those missed backups.
Option A was to delete association of the arch log scheduler during full backup. But when removing association we lose historical data about backup. And we need historical data to be able to create weekly / monthly / quarterly statistics of completed backups. We need to have 99% completed.
Option B was to create two nodes in TSM (TDPO) and one will do full backup only and another one only arch logs backup. So the problem is moved to RMAN. But from RMAN specialist I heard that this may cause problems with full backup. During full backup also archive logs are backed up (at the start and end) so there might be a problem with accessing the file that is used by another process. And this may cause problem with full backup - which we want to avoid especially.
