Hi,

I need to change the global name of the database to a name that does not contain a dot ".", but I am not able to do it.

When I run the script to change the name to a "free-of-dot" name
 alter database rename global_name to <name_without_dot>
it runs successfully, and the feedback is "database altered", but the global name does not change.

Is there a way to change the name as required?

Thanks

Rajy

You could try:
UPDATE GLOGAL_NAME SET GLOBAL_NAME='NewName';

One of the most important rules in Oracle:

DON'T UPDATE DATA DICTIONARY VIEWS MANUALLY

The Global name consists of the database name and the database domain. So a "Global Name without dot" would be a database that has no domain.

Read the documentation for details.

>>Is there a way to change the name as required?

Use same command to change your global name.

SQL> select * from global_name;

GLOBAL_NAME
-----------------------------------
TESTDB

SQL> alter database rename global_name to test.oracle;

Database altered.

SQL> select * from global_name;

GLOBAL_NAME
-------------------------------------------
TESTDB.ORACLE

As per Thomas if you have domain then you can specifiy domain name else leave that.

Have you other stupid things to post?
Maybe you should FIRST try yourself what you tell others to do.

Please do not show your ignorance by commenting on what you do not know:

SQL> select * from global_name;
GLOBAL_NAME
-----------------------------------------------------
SALES1

1 row selected.

SQL> update global_name set global_name='SALES2';
1 row updated.

SQL> select * from global_name;
GLOBAL_NAME
-----------------------------------------------------
SALES2

1 row selected.

Regards to you.

You can also shot you in the head, will you do it?
I do not say you cannot do it but it is a stupid thing.
Now do it on a production database and wait a while to see what happens (hoping you have no database link, streams, logical standby...).

Only the blatant ignorant thinks what he knows is the complete knowledge and calls others ignorant when they point him to something he can't even see he does not know.

Do you think that ALTER DATABASE is just UPDATE?
I have a simple thing and general rule for you to remember:
if you use UPDATE under SYS you are wrong.

Michel

The only situations I know of in which Oracle tell you to manually update the GLOBAL_NAMES view directly are ones where you've already managed to get an invalid value into the Globasl_Name.

What you can do by manually updating the Global_Name isleave your database in a situation where it won't open, and the only option is to restore from backup. (Metalink Note 743676.1).

But of course - you knew all this, and simply neglected to mention it,didn't you.

Note 743676.1
Removed


Global database name has effect on database links when you enforce global naming (GLOBAL_NAMES).
For 11g databases it will be ignored if you configure SERVICE_NAMES.

Obviously the best practice (or recommended) is to set the database global name equal to the service name (or database_name.database_domain). For standby databases and RAC which may have the same service name, you need to set the additional parameter DB_UNIQUE_NAME.
