GLOBAL_NAME

Hi,
If we set the GLOBAL_NAMES parameter to TRUE, then we have to give the dblinks the same name as the remote database. That is the fact. But a dblink is a connection to only a schema for the remote db. If I have to create multiple dblinks to multiple schemas of the remote db, how to do it?
Thanks,

Thanks,consider actually doing as below
CREATE DATABASE LINK TEST1 CONNECT TO USER1 IDENTIFIED BY PASS1 USING 'LINK1';
CREATE DATABASE LINK TEST2 CONNECT TO USER2 IDENTIFIED BY PASS2 USING 'LINK2';
& reporting the results back her

GLOBAL_NAMES setting in 4 nodes RAC

Hi Experts,
I have a 4 nodes RAC with 10.2.0.4 database at red hat 5.1
I find that global_name is nor enforced as
NAME VALUE
global_names FALSE
For stream, I need to change to true.
I want to know which default value for global_name at RAC.
If I change to TRUE and enforce global_nmae. does this changes affects RAC system or some RAC function?
Thanks for help!
Jim

Hello Jim,
Global_Name will not effect anything at the RAC level. This only effects db link name. you have to have use dbname as DB link.
As per best practices document and other streams documentation .. Global_Name should be true. I have tested this. i have made this parameter false however i have created db link used by streams is same as database name which satisfies mandate requirement for streams. because i had to create one more database link in another schema in same database and this was only option.
So in a nutshell.. Global_names enforces dblink name same as dbname. you have a workaround.
Feel free to give it a go.
Thanks

Changing GLOBAL_NAME in 11g RAC

Hi, All -
I am running a two node RAC 11g (11.1.0.7) database on RHEL5. I need to change the GLOBAL_NAME.
SQL> select * from global_name;
GLOBAL_NAME
dbname
SQL> ALTER DATABASE RENAME GLOBAL_NAME TO dbname.companyname.com
I just want to confirm that I only have to run this on one node and fix the db links.
Are there any other steps involved since it is a RAC environment?
Thanks in advance!

That is because when global_names is TRUE, the database link name MUST be same as the global db name of the database to which the link connects to.
You need to drop the database link and recreate it using the global name of the database it connects to.
'link name MUST be same as the global db name of the database to which the link connects to.' - I didn't say 11g.
And I didn't say 'put 11g database global_name=true' because you had already done that! 'after that I set the global_names in 11g as TRUE.
1. 11g - global_names MUST be TRUE
2. 11g - database link name MUST be the same as the global db name of the database to which the link connects to - 10g global db name
3. 10g - gloibal_names setting is irrelevant

LINK to Database with different GLOBAL_NAME

Could anybody help me? We have two databases with different GLOBAL_NAME parameter. First database has GLOBAL_NAME=true, second - 'false'. I would like to make LINK from first database to second. If I make link name as a simple word ('DBST'- for example), ORACLE adds DOMAIN name and connects with error ORA-02085. Second database doesn't use DOMAIN name.
Thanks

How to rename global_name to NEW_DBSID after System Copy

Hello,
I changed SID D22 to S11 during system copy.The System Copy guide recommends to rename global_name on Oracle.
I have some questions.
1) Is the following procedure correct?
SQL>alter database rename global_name to S11;
2) If I do not rename global_name, what happens?
I refer to the guide "Homogeneous and Heterogeneous
System Copy for SAP Systems Based
on SAP Web Application Server
ABAP 6.40 SR1".
6.2 Performing Follow-On Actions in the
Target System
Oracle: If you changed the <DBSID> during the system copy, it is recommended to adapt the global_name parameter with the following SQL command:
alter database rename global_name to <NEW_DBSID>;
If the parameter is not existing on your system, ignore this step.
thanks,
Keishi

Hello Keishi,
just for information.. the official oracle documentation about that topic:
http://download.oracle.com/docs/cd/B19306_01/server.102/b14231/ds_admin.htm
> 1) Is the following procedure correct?
Here is a test in my MDD test database:
SQL> SELECT * FROM GLOBAL_NAME;
GLOBAL_NAME
MDD.WORLD
SQL> ALTER DATABASE RENAME GLOBAL_NAME TO MDD2.WORLD;
Database altered.
SQL> SELECT * FROM GLOBAL_NAME;
GLOBAL_NAME
MDD2.WORLD
SQL> ALTER DATABASE RENAME GLOBAL_NAME TO MDD.WORLD;
Database altered.
SQL> SELECT * FROM GLOBAL_NAME;
GLOBAL_NAME
MDD.WORLD
> 2) If I do not rename global_name, what happens?
If you use a distributed database system, you need to identify each database by a unique identifier (the global name).
For more information, take a look at the oracle documentation:

Global_names parameter. True or false?

Hello,
One of my projects has a live database and a test database, where both have been set up through the DBCA in exactly the same way. I have set up a remote database link for each one successfully.
Only question is one of them i have set the global_names parameter to true and it works fine, while the other database the remote database link would only work when the global_names parameter was set to false. This was after i attempted to create the database link with the same name as the target database.
Can anyone throw any light on why this is the case please?
Thanks in advance

GLOBAL_NAMES specifies whether a database link is required to have the same name as the database to which it connects. If the value of GLOBAL_NAMES is FALSE, then no check is performed. Oracle recommends setting this parameter to TRUE to ensure the use of consistent naming conventions for databases and links.

Global_name and database link

I have Windows XP with 10.2.0.1.0
I have made my database global_name to be junk.points.com.
And, I create a database link as:
create database link preview using 'xxxxx';
the db_link is preview.point.com.
However, if I use the following command:
create database link preview.system using 'xxxxx';
the db_link is preview.system instead of preview.system.points.com.
I expect the db_link should be preview.system.points.com. Please help.
Thanks

Hi,
Specify the complete or partial name of the database link. If you specify only the database name, then Oracle Database implicitly appends the database domain of the local database.
If the value of the GLOBAL_NAMES initialization parameter is TRUE, then the database link must have the same name as the database to which it connects. If the value of GLOBAL_NAMES is FALSE, and if you have changed the global name of the database, then you can specify the global name.
Defining a CURRENT_USER Database Link: Example
The following statement defines a current-user database link to the remote database, using the entire service name as the link name:
CREATE DATABASE LINK remote.us.oracle.com
CONNECT TO CURRENT_USER
USING 'remote';
The user who issues this statement must be a global user registered with the LDAP directory service.
Please view the below document.
http://www.stanford.edu/dept/itss/docs/oracle/10g/server.101/b10759/statements_5005.htm
http://download.oracle.com/docs/cd/B28359_01/server.111/b28310/ds_admin002.htm
And please check the db links you posted one is having __.point.com
and the other one is having ___.points.com
Please make sure you are using the GLOBAL_NAMES set true and displaying correct dblink .
Hope this will be helpful :)

Global_name object type

Hi,
To know global name of a db we use "SELECT * FROM *global_name*". But what is the type of the object global_name? I could not find anything abt it in dba_objects.
I am sure its not a parameter since there is a separate parameter global_names, and we are not using sho parameter but select *.
Please let me know what is this global_name
Regards,
Saikat

I am sure its not a parameter since there is a separate parameter global_names, and we are not using sho parameter but select *.Are you sure? :
SQL> select table_name from dict where table_name='GLOBAL_NAME';
TABLE_NAME
GLOBAL_NAME
SQL> alter session set global_names=TRUE;

Global_name changing

I saw in one document that say global_name=db_name+db_domain.
My db_name=d
and db_domain=d.com so global_name=d.d.com
Ok fine.
Now I changed my database global_name using
alter database rename global_name to change;
now whenever I query,
select database_name from dual or select * from global_name it shows to me global_name=change;
But the db_name and db_domain remains same.
So where went the statement global_name=db_name+db_domain???
Anyone there clarify me.

The global database name is the unique name of the database. In a distributed
database system (a set of databases stored on multiple computers that typically
appears to applications as a single database) the global database name ensures
that each database is distinct from all other databases in the system.
The global database name defaults to DB_NAME.DB_DOMAIN and this value is marked
at database creation time. If you change the DB_NAME or DB_DOMAIN after the
database has been created, the value for the global database name (GLOBAL_NAME)
will not change.
Also ALTER DATABASE RENAME GLOBAL_NAME will change the global database name, but will not change the value of the DB_NAME or DB_DOMAIN parameters.
Check this documentation -

Changing global_name

Oracle 10.2.0.2 Ent edition on AIX 5.3
My db name is db1 and by mistake i edited global_name to db1.oracle.com as below,
ALTER DATABASE RENAME GLOBAL_NAME TO db1.oracle.com;
Actually global_name is db1 itself since db_domain parameter is null.
SQL> show parameter db_domain;
NAME TYPE VALUE
db_domain string
SQL> show parameter global_name;
NAME TYPE VALUE
global_names boolean TRUE
SQL> select * from global_name;
GLOBAL_NAME
DB1.ORACLE.COM
SQL>
Now i am not able to revert it back to db1 with the sql: ALTER DATABASE RENAME GLOBAL_NAME TO db1
Any idea on how to revert the global_name to db1
~Thnx

See MetaLink Note# 382994.1
If the db_domain was NULL and GLOBAL_NAME was changed to include a domain name, it cannot be changed back again. The only "fix" provided by that note is to update PROPS$.
Since updateing PROPS$ is not supported, you should log an SR with Oracle Support for confirmation.

Significance of Global_names parameter in Oracle CDC and Oracle Streams

Hi,
I am trying to implement a sample Oracle CDC example.
I read in some examples that we need to set a parameter *'global_names= TRUE'*. (which means that all dblink names should be same as their respective database names)
But my doubt is that what will happen if i use the default value 'FALSE' for this parameter without changing it to 'TRUE'.
Is it mandatory to make 'global_names= TRUE' ?
Could anyone please explain this.
Thanks in Advance
Regards,
Gowreesh.

Hi Sybrand,
Thanks for the reply.
Currently there are some dblinks in my database(with dblink names different from the database).
My concern is,
If i make global_names=TRUE, then all my earlier dblinks with that database will not work.
and if I DONOT make global_names= TRUE, then i will not be able to work with Oracle CDC/Streams with the database.
I am looking to find out any work around to overcome this deadlock type of situation.
I would be very thankful if you can give some idea to come out of this problem.

Gowreesh

Hi Madhavi,
You said:
OMB+> OMBALTER LOCATION 'TEST_LOCATION' SET PROPERTIES ( HOST, PORT, SERVICE_NAME , SCHEMA, CONNECT_AS_USER,PASSWORD, VERSION, UOID,DATABASE_NAME) \
VALUES ( '$HOST', $PORT,'$SERVICE', '$TgtDBUser', '$TgtDBUser', 'TgtDBPWD','$
dbversion','true','$SERVICE');
Did you leave out the "$"-character for the TgtDBPWD variable in purpose? Could this be the source of your problem?

Change global_name risk

what do you think the risk, after you change the global_name of the database. (using alter database rename global_name to aaa.bbb command)
In my system, previous database link is not work, I think this is only a little thing that I can handle, just only rebuild a new database link.
But the problem is if you changed your database global_name, you would hardly to change back to original name while database running, and if you don't delete the database link which is unvailable, maybe unsee error will be occured, In my case, if you access the bad database link, sometime will cause database memory corrupt. I don't know if there is any relation. could you solve my confusing?

Check my posts in this thread
urgently! remove oracle database domain name
There's no risk to change global_name if you follow Oracle document.
I think your problem only happen after you update a data dictionary table directly.

Databases link name required without global_name

Hi,
My global_name is "ORCL.REGRESS.RDBMS.DEV.US.ORACLE.COM" when i create any database link the name create like "U_NET_LINK.REGRESS.RDBMS.DEV.US.ORACLE.COM"
How i eliminate global_name without edit my initora file using SQL .

Faheem

You need to check parameter global_names
alter system set global_names=true scope=both;
System altered.http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/initparams077.htm#CHDGEHBB
Also what's your DB_NAME and DB_DOMAIN set at?
Your global name looks rather erratic.
