i am fairly new to db administration and need some help. I am trying to create a db link to a new development box and receive the following:
ORA-02085: database link DBDEV.WORLD connects to BDOP.WORLD
BDOP = production SID and where I am trying to create the link
DBDEV = new development SID that I am trying to create a link to
Some db links were created before my involvement to TEST db on seperate box and are successful.
Steps that I have taken:
(1) Made sure that the link name is after the db that I attempt to connect to.
(2) Tried setting 'global_names = false' but received the same error.
(3) Tried creating a link from DBDEV to BDOP but received:
ORA-12154: TNS could not resolve service name
Although I have assured that each db's tnsnames.ora file is updated.
I am obviously missing something and I am not sure what. Is ther a config file that I did not update or another parameter that I need to modify? Any help would be appreciated.
post your SQL to create the db link. that might help us help you.
The GLOBAL_NAME parameter was changed on the target DB?
The SQL code is:
CREATE PUBLIC DATABASE LINK DBDEV.WORLD@BDOPS
CONNECT TO BDOPS IDENTIFIED BY *
I changed 'global_names = false' on the source db.
Thanks for your help.
I think there is a restriction that your db_link name should be same as the SID name.
Also I think there is a restriction on the size of the SID name...can't be more than 4 characters; what is DBDEV (5 characters ?)
What version of ORacle are you using ?
Thanks for the help but I figured out the problem. I created DBDEV by transferring datafiles from BDOP and doing a BACKUP CONTROLFILE TO TRACE. Copied over the init.ora, etc... The step that I missed was issuing the following command on new db:
alter database rename global_name to DBDEV.WORLD;
Everything is working now.
Thanks for the input.
