Graceful Switchover (GS) Examples

Owned by Anton Els (Deactivated)
Last updated: Apr 28, 2016

This section will show examples on running Graceful Switchover (GS) process.

Before running Graceful Switchover, it is important to make sure that you have executed Dbvisit Standby to send/apply logs followed by reviewing the log gap report to ensure the Primary and Standby databases are in sync.

During the graceful switchover (which is a controlled role reversal between the primary and standby, the redo logs from the primary database is copied to the standby database. It is important to keep in mind that if the redo logs are large, this process can take time.

 

This process can also be run from the Web Based (GUI) interface - Performing a Graceful Switchover via GUI

 

Example: Running Graceful Switchover in a Single Instance Linux environment:

In this example the primary server is called "dbvlin101" and the standby database server is called "dbvlin102" with the database being called "testdb".

The DDC name for this database is also called "testdb".

 

Step 1:  Make sure logs are sending and applying

Send Logs from Primary:

Step 2:  Review the Log Gap Report

For more details on the log gap report please see: Dbvisit Standby Log Gap Report

This is executed from the Primary Server: ./dbvisit -i DDC

 

oracle@dbvlin101[/usr/dbvisit/standby]: ./dbvisit -i testdb
=============================================================
Dbvisit Standby Database Technology (7.0.34.13526) (pid 1595)
dbvisit started on dbvlin101: Wed Jan 28 08:40:51 2015 ()
=============================================================
Dbvisit Standby log gap report for testdb at 201501280840:
-------------------------------------------------------------
Standby database on dbvlin102 is at sequence: 44.
Primary database on dbvlin101 is at log sequence: 45.
Primary database on dbvlin101 is at archived log sequence: 44.
Dbvisit Standby last transfer log sequence: 44.
Dbvisit Standby last transfer at: 201501280800.
Archive log gap for testdb:  0.
Transfer log gap for testdb: 0.
Standby database time lag (HH:MI:SS): 00:39:49.
=============================================================
dbvisit ended on dbvlin101: Wed Jan 28 08:40:54 2015
=============================================================

 

In summary, the two key lines here is to review the archive and transfer gaps.  These values should be 0.  (When using Oracle RAC, the archive gap must be 0 or 1)

 

...
Archive log gap for testdb:  0.
Transfer log gap for testdb: 0.
...

 

Step 3:  Starting the Graceful Switchover Process

The Graceful Switchover process, is a two-step process.  You have to execute the same command on both the primary and the standby database server:

./dbv_oraStartStop switchover DDC <unique_number>

The <unique_number> should be the same one on both primary and standby, (this number is not used for anything else and is just a random number)

In this case the commands executed are

On Primary: ./dbv_oraStartStop switchover testdb 1001

On Standby:  ./dbv_oraStartStop switchover testdb 1001

 

This process can run for a few minutes, (depending on the size of redo logs and network capacity).

It is important to test the Graceful Switchover process in your test environment to make sure you are familiar with the process.

You should also document and take note of timings so that when it is executed in a production scenario, you are familiar with the process and the timing

 

Example output:

This database (testdb) is now the primary database.
You may consider re-creating a password file to make sure all sysdba passwords are preserved.
To keep the standby database on dbvlin101 in synch with this primary database,

Once the process is complete, there is one important step required.  Run Dbvisit Standby on the new primary, followed by running it on the standby to make sure logs are shipped from the new primary and applied to the standby.

 

Step 4.  Run Dbvisit Standby

First run dbvisit on the new primary:

Graceful Switchover is now complete.

 

When using Oracle RAC take the following into account:

 

  1. The Graceful Switchover (GS) is only executed from one of the primary nodes (the one which you want to become the standby database).  The other instances can stay running, they will be shutdown as part of the Graceful Switchover process.
  2. You still need to execute the GS command on the standby node as well. 
  3. Make sure you are able to ship logs from both primary nodes to the standby node
  4. Run the log gap report and make sure that the standby database is up to date.  When using Oracle RAC, the Archive log gap on one of the nodes may be 1.  Values more than 1 will not be allowed and the GS process will request that you first run Dbvisit Standby to send/apply logs to reduce the gap to 0 (or 1).

 

Example, if you have a two node Oracle RAC environment, and a single instance standby database, and you want to perform a switch to make primary node 1 the new standby node and the standby node becomes the primary node, you have to execute the graceful switchover command on node 1 and the standby node.  The instance on node 2 will be shutdown as part of the graceful switchover process.

 

Example running Graceful Switchover on a 2 Node RAC with a Single Instance Standby

The RAC environment consist out of:

  • Node 1 - dbvrlin301
  • Node 2 - dbvrlin302

The RAC database is called TSTRAC with instance TSTRAC1 on node 1 (dbvrlin301) and TSTRAC2 instance on node 2 (dbvrlin302)

The standby database environment is a Single instance standby server called dbvrlin305 with standby database.

 

 

Primary RAC Node 1Standby Server (Single Instance)

Step 1 - run log gap report - make sure gap is no more than 1.
