Overview

This guide explains how to change the DB_NAME without rebuilding the database.
 
 

Method

1. Check current DB name

Example DB name (Before change: jh_tibero / After change: jh_tibero2)
SQL> SELECT INSTANCE_NAME, DB_NAME, HOST_NAME FROM V$INSTANCE;

INSTANCE_NAME        DB_NAME              HOST_NAME
-------------------- -------------------- --------------------
jh_tibero            jh_tibero            linux84

2. Shut down the instance

$ tbdown immediate

Tibero instance terminated (IMMEDIATE mode).

3. Start in mount mode

$ tbboot mount
Change core dump dir to /home/tibero/tibero7/bin/prof.
Listener port = 8833

4. Change DB name

$ tbsql sys/tibero

SQL> ALTER DATABASE RENAME TO "jh_tibero2";

Database altered.

5. Shut down the instance

$ tbdown immediate

Tibero instance terminated (IMMEDIATE mode).

6. Confirm DB_NAME change and apply

After changing the DB_NAME in the tip file to <new DB_NAME>, verify the DB_NAME in the tbdsn.tbr file.
$ cat $TB_HOME/config/$TB_SID.tip | grep DB_NAME
DB_NAME=jh_tibero2

$ cat $TB_HOME/client/config/tbdsn.tbr
jh_tibero=(
   (INSTANCE=(HOST=localhost)
             (PORT=8833)
             (DB_NAME=jh_tibero2)
   )
)

7. Start in NORMAL mode and verify DB name

$ tbboot
Change core dump dir to /home/tibero/tibero7/bin/prof.
Listener port = 8833

SQL> SELECT INSTANCE_NAME, DB_NAME, HOST_NAME FROM V$INSTANCE;

INSTANCE_NAME        DB_NAME              HOST_NAME
-------------------- -------------------- --------------------
jh_tibero            jh_tibero2           linux84

Note

โ€ป If you need to change TB_SID, use the following method.
 
  • Copy the existing tip file and rename it to <new_DB_name>.tip.
    (For TAC environments, rename to <new_DB_name>1.tip)
  • If necessary, update TB_SID=<new_DB_name> in the .bash_profile.
    (For TAC environments, set TB_SID=<new_DB_name>1.tip.)
  • Also change the existing DB_NAME entry to <new_DB_name> in the tbdsn.tbr file.
