For a one week, oracle database (v 9.0.1.0.0) is hanging frequently.I could't showdown/restart the database. After restart the server (RedHat), the database is opened without any problem.after 9 or 10 hours once again hanging. too large spaces are availble in my HardDisk.

I am using oracle 10g and toad 11.5 . i am trying to call an api from an anonymous block . If i recompile the api after adding dbms_output.put_line and then try to execute the anonymous block ,it shows error as "ORA-06508: PL/SQL: could not find program unit being called". However if i end current session and open a new session , then the anonymous block will execute without the error. i am made to reconnect the session everytime i make a change to API. making any configurations in toad or database level.

View 8 Replies View RelatedI have a trigger on insert which sets a :new field if it is net set.Basically:
CREATE OR REPLACE TRIGGER my_schema.T_OBS_BEF_IU
BEFORE INSERT OR UPDATE ON my_schema.OBS FOR EACH ROW
BEGIN
If :new.work_db is null Then
:new.work_db := my_package$PARAMETER.Get_label ('DEFAULT_WORK_DB'); -- function returning varchar2(200)
End if;
END;
/
It usually works fine. With jdbc, when the application insert a null value, the trigger replaces it with the good value.When the application can determine the non-null value, it is written in the table.
But when the trigger is restarted to a savepoint, due to a table lock, the second execution of this trigger goes wrong. The input :new.work_db value is not null anymore, nor has the correct value. Most of the time, it has the ascii 00 value (NUL), sometimes another weird character.
Do you know if my trigger code is correct, or if there would be some limitations ?
11g RAC environment, I manually shutdown the database with "shutdown immediate" and stop the listener with "lsnrctl stop". Later I manually startup only the database but the listener is also started automatically at almost the same.
Why would this happen ? I just don't want the listener to startup automatically at that time. What can i do to prevent the listener from auto-starting when i startup the database manually.
My client get the error Ora-12514 when he tries to connect to the db.Well;
1) we restart the services: "OracleServiceOrcl" and listener but nothing changes
2) We restart the server and nothing changes
3) We checked the dump and he was done on March,26th. No db export yesterday. Is there any link with the clock change of this week-end (location of the server: France)?
4) The lsnrctl services listener command run successfully but it doesn't mention the instance ORCL.
Is there a way to restart emctl agent12 ? if yes, could you provide me the steps / command ?

To improve redundancy we're planning to change the network configuration in our Oracle Restart environment from using 1 LAN interface to a bonded interface consisting of 2 interfaces.So the change will be from using "eth0" to using "bond0" consisting of "eth0" and "eth1". Are there any changes that must be done in the Oracle Restart configuration to reflect these changes?

View 2 Replies View RelatedI just finished my first course in SQL for Oracle 11g at my local community college. We used SQL*Plus for the coursework and for the next class I need to use SQL Developer. Initially, I installed the Developer and was unable to establish a test connection due to the listener not being installed. I fiigured out that I needed to use the Network Configuration Assistant to add and configure the listener. After doing so, I was able to connect using Developer. The issue, however, is that any time I restart my computer, the TNS Listener service disappears from the list of services in Task Manager and I have to delete and then add and configure the service again using Network Configuration Assistant. Obviously, the Listener still exists because I can delete it and then recreate it.

View 2 Replies View Relatedi have created a database on my pc and i have given a password at the time of installation , after the installation it is accessed successfully by the given password , but i observed that when i gave anything in password then it is also accessed by it and i don't have any other database of this same name.
And when i access it through another system then it is accessed only by its original password not by any other password.
how can i secure my database from hacking by any one of these:
1-sql injections
2- DON(Danial Of service)
3- buffer overflow
4- listner hack
I am fairly new to Oracle and have recently started learning the basics of Data Guard. I have set-up a Primary 11g database which successfully ships and applies logs to a Single Standby (on the same server) as expected. Manual switchovers work fine; however, I have found a slight problem when performing switchovers using the Data Guard Broker utility.
The switchover is successful- but the broker cannot restart the Primary instance. The strange thing is that when I perform a switchover in the opposite direction (i.e. the new Primary goes back to standby again) it works fine. The error is receive is: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor.
The majority of posts I have seen on this topic seem to point to incorrect listener / tnsnames set up but they have exactly the same values. If both databases are identical, why does it work one way but not the other? I will provide any necessary files to pinpoint where the issue could be.
We have Employee table, there is a field name Employee_no. field size is 6.can we restrict some one not to increase or decrease the field size of Employee_no. even User has admin role.
is there any way to restrict admin user that he should not allow to enter the value of field more or less than 6 characters through Toad or SQL Plus 8.0.
------------------------------------------------------
for example
field: employee_no
feild_size: 6
field_type: Varchar2
When we enter Employee no A000001(7 digit) then database not allowed to update because its field size is 6 characters we want to restrict admin user in Toad or SQL Plus 8.0 because he is Toad and SQL Plus user.
Is there any setting on oracle that allows to disconnect users automatically and display a message to users such: "Try a new connection to the db in 30 minutes"?
