Log Shipping with clustered database.

Hi,
We are running SQL Server Failover cluster in Active/Passive mode.
Now, we want to setup DR server for this clustered database using
Log shipping.
But my concern is, can we do log shipping with clustered database ?
and the answer of this question is Yes then Please let me know How ?
Thanks & Regards,
Sajid C.
Yep...you can. Just like how you do it in a non-clustered instance. The only
problem you will have in here is if you want to be notified thru email if
your restore jobs fail as MAPI is not supported in a clustered environment.

log shipping between sql 2005 clusters

hi

I am working for a small govt dept.We are planning to implement sql 2005.

We will be having sql 2005 instance in active/passive cluster mode

We will also have a standby sql server 2005 in active/passive cluster mode.

i need to know how to configure log shipping between my primary and secondary?

Is logshipping the best option?

Thanks

Is logshipping the best option for what? Logshipping is a fine technology but there are other ways to get data to a secondary server. You can use database mirroring in SQL Server 2005. For failover purposes this is a great option. You can also use database snapshots on the same server for various reasons to. Logshipping is perfectly viable too. What are you trying to accomplish? Having redundancy outside of the cluster? Read Only reporting copy of data?

Having that info can help us help you make your choice. I would say look up in Books Online Logshipping, Database Snapshots and Database Mirroring.

Thank you very much for the reply.

I need to have an exact replica of the live enviornment (production cluster) to be switched to (standby cluster) in case of any probs to the primary. We also do switching between primary and standby every week. Basically the standby is like having a disaster recovery site. Its having Redundancy outside the cluster.

Please suggest....

Thanks in advance

Options are

Database Mirroring

Can be operated in Synchronous mode which means your standby will be an exact replica of your primary database. Switching between the two is easy.

However it doesn't support replication and in synchronous mode the data has to be written to the standby and so may impact performance of your app if your network connection isn't great.

You can work in Asynchronous mode in which case the data is written to the standby at some point after the application has finished the transaction, i.e. no impact on the application. However in this mode you may loose data if your primary goes down and the transaction hasn't made it to the standby.

Database Mirroing has automatic failover in the event of a failure (when used with a witness server)

Log Shipping

Very much like asynchronous mirroring however it supports multiple targets i.e. you could have 2 standby servers, you can't do that with mirroring. Also the mechanism for applying the logs is via a copy and restore model which is slightly different to mirroring.

Replication

Much more complicated than the two above but allows for your production to be in read/write mode (although changes are not replicated back to the primary). This is a great option for maintaining a reporting server as you can have different indexes on your reporting database.

Personally if your two clusters are connected by a highspeed network (Gb/s) I would go for synchronous mirroring.

More details can be found here

Log Shipping between 2 Clusters

Hi
I'm trying to setup log shipping between two 2-node Active/Passive clusters and I keep getting an error "Unable to copy the initialization file to the secondary server".
I've search KB, to find an article KB/811890, but both clusters are in the same domain, and thus this article shouldn't apply. However, I'll try anything, so I have re-registered the second (log ship recipient) cluster as per the recommendations (SERVERN
AME.DOMAIN), but still get the same message.
I know its probably me that doing something wrong, but I'm stuck at what.
I have tried registering the instances in the following ways.
- Using the Cluster name (as opened within Cluster Administrator)
- Using the Virtual Server Name (as provided within the SQL Install)
- Using the Cluster IP Address
- Using the Virtual SQL Server IP Address
In all cases, I either get the same error, or don't get that far.
Can you please assist?
Thanks, in advance for your assistance.

Try the following to see if it helps
1)Run the stored procs (http://support.microsoft.com/default...&Product=sql2k) to clean up log shipping.
2)Verify that the SQL Server and SQL Server Agent services on primary and secondary SQL Servers are running under a domain account
3)Verify with your NT Administrator that there is a two way trust between the domains.
4)Log on to primary server using the domain account used to start SQL Server services on primary server.
a)Open Query Analyzer and use xp_cmdshell command to copy a file (any file will do) from the share on primary server (i.e. the share on primary server where you
want the transaction log backups to be stored) to the share on the secondary server. If you get error like access denied then we will need to fix this first.
b)Open Enterprise Manager and verify that you can register the primary and secondary SQL Servers.
c)Verify that the database you want to use for log shipping does not have SIMPLE Recovery model.
d)Verify that that the domain account that is used to start SQL Server services has access permission to the database that you want to use for log shipping.
e)Configure Log Shipping.
