Caution

The tbcm process must be started as the root account, and the tibero process must be started as the tibero account for the VIP to be up.

 

14. Start Standby CM & DB

14.1 Restart Standby CM

To use VIP, start CM as the root account. (If you do not use VIP, you can skip this step.)

$ tbcm -d
CM DOWN SUCCESS!

$ su -
$ cd ~tibero or cd /home/tibero (navigate to $TB_HOME path)
$ . .bash_profile

$ tbcm -b

14.2 Start Standby DB in mount mode

Before starting the Standby DB in recovery mode, you need to replace the control file obtained from the Primary DB with the standby DB control file.

$ su - tibero

$ tbboot mount

15. Start Primary CM & DB

15.1 Start Primary CM

To use VIP, start CM as the root account. (If you do not use VIP, you can skip this step.)

$ su - tibero
$ tbcm -d
CM DOWN SUCCESS!

$ su -
$ cd ~tibero or cd /home/tibero (navigate to $TB_HOME path)
$ . .bash_profile

$ tbcm -b

CM Guard daemon started up.
import resources from '/home/tibero/tibero7/config/cm_res'...

TBCM 7.1.1 (Build 303667)

TmaxTibero Corporation Copyright (c) 2020-. All rights reserved.

Tibero cluster manager started up.
Local node name is (PRIMARY:18632).

 

15.2 Start Primary DB

$ su - tibero

16. Verify TSC synchronization

Check by querying the test table on the Standby DB.

$ tbsql sys/tibero

tbSQL 7

TmaxTibero Corporation Copyright (c) 2020-. All rights reserved.

Connected to Tibero.

SQL> alter database open read only continue recovery;

Database altered.

SQL> select count(*) from tibero.tsc_sync_test;

  COUNT(*)
----------
        99

1 row selected.

 

Check TSC status

1.1 Check connection status with Observer

You can check the connection status of PRIMARY and STANDBY on the Observer CM.

$ su - obs

$ cmrctl show

==============================================================================================

 

 

1.2 Verify Primary DB connection

You can check by querying the v$standby_dest table on the Primary DB.

$ tbsql sys/tibero

tbSQL 7

TmaxTibero Corporation Copyright (c) 2020-. All rights reserved.

Connected to Tibero.

select flags from v$standby_dest;

1.3 Check VIP status

In the TSC configuration, the VIP runs only on the active server.

  • If the Primary node is up, the Standby node is down
  • In failover, the Standby node changes to up state

Observer modes

There are two observer modes: PROTECTIVE and DISASTER_PLAN. By default, PROTECTIVE mode is applied when the CM starts. To use DISASTER_PLAN mode, you must manually change it each time the observer restarts.

TypeDescription
PROTECTIVEFailover occurs when a problem happens with the Primary DB (when DB shuts down)
DISASTER_PLANFailover occurs when there is an issue with the Primary cluster (when CM or DB shuts down abnormally)

 

Change Observer mode

Perform the following to change the mode.
