Delete the database

Hello frnds
In my test server I have to delete my database including all tablespaces and datafiles everything and create the new database with new character set which i need ,
So i just need a sujjestion which is best method to delete a old database ...
simply delete all the files from Operating system or is there any safe method to delete database
environment:
OS: Sunsolaris 10
database:10g R2
your sujjestions will be valuable for me
thanks

Hi!
It's completely up to you how you delete a database. You may do it with OS rm command without any problems. Another way that is as safe as the rm command is the database configuration assistant that is also able to delete your DB. It is also possible to delete your DB with the DROP DATABASE commando from SQL*Plus. As I know there is no big difference in all three ways. My favorite way to drop a database is the DBCA because it is easy to use.
yours sincerely

Delete the database without shutdown!!!!

Hey all....

spid24s An exception occurred while enqueueing a message in the target queue. Error: 15517, State: 1. Cannot execute as the database principal because the principal "dbo" does not exist, this type of principal cannot be impersonated,
or you do not have permission.

Hi Paul,
I also had the same error on one of my servers, and it was because the user that created the database no longer worked for the company.
So when his AD account got deleted, the database had NULL as owner
Using the following query I asked for the owners of the databases:
select name, suser_sname(sid) from master.dbo.sysdatabases
So changing the owner of the databases that had a NULL owner solved the issue for me.
use <databasesname>
go
exec sp_changedbowner 'sa'
Thanks for triggering the solution.

Problem in starting the database

hi for all
i have installed successfully 10g on my redhat system and it is just work fine , but after the first reboot it gives me this error on sqlplus
Enter user-name: system
password:
ERROR:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Linux Error: 2: No such file or directory
when trying to login via isqlplus gives me this error
TNS:listener does not currently know of service requested in connect descriptor
so i run dbca and i have deleted the database and created a new one and it's again work fine i reboot the system again the above errors again occurs.
thanks

The problem here is that neither your database nor your listener are started. You should use regular commands to start them up.
sqlplus /nolog
conn / as sysdba
startup
exit
lsnrctl start
export ORACLE_SID=instanceName
emctl start dbconsole
If you want to start services automatically, then you should configure your linux environment to start processes automatically at OS start time.
For automatic startup / shutdown you may want to check Oracle documentation: 2.2 Automating Shutdown and Startup

How to delete unwanted databases that keep coming back?

Hi,
Besides the usual Google mail database I have somehow acquired 2 other databases that I want to get rid off because I don't trust them.
The first is the one a lot of other people seem to have as well RLDGUID and the other one is from a blog I visited. It's called sql-evercookie.
I know how to delete the databases but when i do that they just pop back up. I have tried a lot of things, there isn't much you can do, I delete all my cookies, cache and history, rebooted the iPad. Nothing works. There must be a way to get rid of them right?
I especially upset about the sql one. It's from a friend's blog who hired a company to design her a ' professional' blog. Why that has to include putiing databases on people's devices I don't know but I sure will ask. In the mean time I want it gone.
Anyone has any ideas?

So you never received a response to this? Did you ever get an answer. I just found some on my original...not ipad2.
Thanks!

Delete oracle database

how to delete oracle database from OEM?
regards
wire

You can't delete the database from OEM.
You can do it either manually or using DBCA (database configuration assistant) utility supplied by oracle.
I believe 10g has drop database command.

Aperture crash when start and the database is damaged

Hello
I have been playing around with a trial of Aperture
My mac crashed when i was importing a big library -my fault, because the hot-
After that Aperture has not been able to start, until i have deleted the database -moved to a different location-
Is this the normal behaviour when the database is broken?
Would be nice if Aperture was able to "keep alive" even when the photo database library was broken
Something like "Sorry it seems the library has a problem, do you want to create a new one or choose one that actually exists?"

Deleting Oracle Database.

Hi
Current Enviroment : Oracle 10g/ Windows 2003 Server.
On one of our Prod Server, in addition to the Prod Database that we have another database that we would like to delete.
Can anyone suggest me whats the best method of doing this.
1) Delete the database using DBCA
or
2) Delete the instance using ORADIM command and then delete all the respective files of this other database.
If both the methods are just the same, i would like to go with Method -2 , seems to be safer keepin in mind that we have a Prod DB on this box.
Please suggest me on this issue.
Thanks
Vamshee

Reg:How to delete the column in table control also from database table.

Hi Experts,
Once again thank u all for giving the responses.
one more doubt is how to delete the columns of table control and also the record shold delete from ztable.
With Regards,
Saroja.P.

Hi,
If you want to delete the rows in the table control and simultaneously delete it from the database table, then you can implement a 'DELETE' functionality specific to your table control. Have a MARK field (you will find that in the screen attributes of the table control -> give a name for the MARK field, you will find an additional MARK column at the beginning of your table control). You can check whatever rows you want to delete from the table control, call the delete module.
"This portion of code inside the LOOP...ENDLOOP.
IF sy-ucomm eq 'F_DELETE'.
gt_itab2-check = mark. " Store the MARK field status into your internal table's correspoding field 'check'
MODIFY gt_itab INDEX tabcontrol-current_line.
ENDIF.
iF sy-ucomm eq 'DELETE1'.
DELETE gt_itab WHERE check eq 'X'. "Your internal table does not have rows that you want to delete
ENDIF.
Now you can modify your database table using the MODIFY statement.
MODIFY ZDB FROM TABLE gt_itab.

Delete record from the form and from the database

hi,
i want delete record from the form and the database ,but the record is only delete from the from !!!
this is my code :
if //condition then
delete_record;
commit;
end if ;
Any solutions ??
thnx

You have unique key field(s) on the table you are trying to insert which actually restricts you from inserting the same value again.
When you are deleting the record and issue commit there is a record to be inserted in the table which is a duplicate that's why you are getting this unique error.
As oracle is not able to insert your commit fails and stops your deletion of record from table

How to delete the content of a datatable by the "Database Adapter"

Hello,
i want to delete all entries in a table by a database adapter - like "DELETE FROM table" in SQL. (Oracle SOA Suite 11g SR1, with Oracle DB over JDBC))
When i create a new Database adapter i can select standard functions for "insert, select, delete". The function delete does have the disadvantage, that it needs a input message with the key values of the data entry which have to be deleted, which i don't have and don't want to get.
So i tried the "Pure SQL" mode for the adapter with the SQL string "DELETE FROM table" but this instruction is somehow not commited to the database.
My questions are:
- Is there any commit needed for the pure sql instructions? How is the syntax to write several SQL instructions for one Database Adapter?
- Does anyone have another solution to delete the entries?
Thanx in advance
Tobias

Hi Shishir,
it is a pretty simple example. I think the problem is that the Database Adapter is not commiting.
The BPEL is simple sending an empty message to the adapter which should trigger the SQL execution (See Code below)
The PURE SQL String i'm using is "DELETE FROM table"
Thanks Tobias
