Log Shipping Sql Server 2005

Log Shipping Sql Server 2005 – Last week I performed a server migration from SQL Server 2014 to SQL Server 2016 using . A lot of work is done in advance to prepare and plan so that these migrations have the least impact on our clients. That’s why I always do my best to improve the process every time we do it.

This is the second production server we migrated to SQL 2016. The first migration had automation to some extent.

My comfort level with last year when the migration was done was low, so the migration was a combination of TSQL and manual processes.

Minimal Downtime Migrations Using Invoke Dbalogshipping

The goal this time was to improve the process with more automation. With that in mind, I decided to use the Invoke-DbaDbLogShipping command to create the log shipping for the primary database that was part of the migration. The current database size is 650GB, which isn’t too outrageous, but it’s growing at 30GB per day and by Wednesday my differential backup would have been 90GB. Therefore, backing up and restoring it would have taken a long time during the migration window.

The reason I decided to go with Log Shipping is how easy it is to set up, and the commands make it even easier. Also, the ability to reduce downtime I mentioned above, even for large databases.

Log submissions also support mixed versions from 2005 to current versions and mixed editions such as Standard, Workgroup, or Enterprise that have no other migration options. Check out this great article on using Log Shipping to reduce downtime for more details.

So we use our standard build configuration process to configure the servers to our standards. This process has not been used as I expected, but time has been my enemy on that project. Right now we have 12, there are 12 environments for each of our products. That means this exercise is performed 12 times before it’s all said and done.

However, this time we did things a little differently. Our development teams now follow the agile lifecycle and run two-week sprints. For our first step, we migrate the main continuous integration environment and the main integration environment using the automated process. However, log ships do not come into play due to the size of these environments. So it gives us practice and testing of the migration process. Then, in the next sprint, we migrated the Regression and Production environments. This is where the fun begins.

Last week I decided to use Invoke-DbaDbLogShipping to create the production database on the new server and keep it in sync with the existing server.

Once all jobs have been verified to be working from the correct locations, you can see that the built-in Transaction Log Submission Status report shows that we are up to date on our log submission.

I didn’t use the following command because I hadn’t had time to do any testing. I used TSQL then, but after trying this now it would have been even easier. Invoke-DbaDbLogShipRecovery disables the jobs and then brings the database online.

And so, we finish. A total of 17 minutes of downtime for our product and we’re back, with only iteration and RE to do after the fact.

If the database has not yet been initialized on the secondary instance, this can be done by selecting an existing full backup and restoring it for you.

If a database has not yet been started on the secondary instance, it can also be done by telling the command to create a new backup and restore it for you.

Early previews of the next version of SQL Server, codenamed Denali (SQL Server 2012), indicate that this trend will continue. Somewhere in the midst of new availability technologies and feature sets, log shipping seems to have fallen by the wayside. Although trunk shipping received a much-needed facelift with SQL Server 2005, SQL Server 2008 saw only minor improvements.

Although log shipping is not as widely used as it once was, it is still an essential tool that has many applications, such as using hot standby systems for disaster recovery, migrating large databases, and accessing read-only to the data. Log shipping is not difficult to understand or use. There are three techniques that can save you a lot of time and make working with log shipping easy: reverse log shipping, switching between log shipping and database replicas, and converting log shipping to transaction replication.

Packing your trunk is an often overlooked practice. When DBAs need to failover to a secondary log shipping server, they tend to worry about recovering log shipping later. This is especially true for very large databases. If you are using log shipping as your primary disaster recovery solution and need to fail over to the secondary log shipping server, you should run log shipping as soon as possible. Without a disaster recovery failover in place, you may be running out of resources.

Packing the log boat is simple. There is no need to restart the database with a full backup if done carefully. However, it is essential that you remember the following:

Note that steps 7 and 8 are listed as optional because they are not required to configure log shipping. However, I recommend performing these steps to ensure that the log shipping setup goes smoothly.

With some minor modifications, this 10-step process works with multiple secondary log shipping databases. Perform the same basic steps, keeping in mind that the other secondary databases will remain secondary databases after the failover. After you have backed up the log to the new primary database, you must use the NORECOVERY option to restore that backup to all proposed secondary databases. You can then add them as secondary databases to the new primary database.

Log Shipping Notes

Log shipping and database mirroring start with a full backup and both depend on the LSN chain for synchronization. This similarity makes it possible to switch between the two without rebooting with a full backup. This technique is useful when you have configured log shipping or database mirroring and want to switch to the other technology for a short time. Change can go in any direction. For example, I use this technique when I need to perform maintenance on log shipping servers.

Switching between log shipping and database mirroring does not involve manual backups or restores of the database. It’s as simple as removing any technology that is configured and then configuring the other. However, a key concept to remember is that you should prevent backups from taking place when neither technology is configured.

When there is a short-term failover, I recommend switching between log shipping and database replicas because this technique requires much less configuration work than reverse log shipping. When a temporary failure is intended to be long-term, the best technique to use is log boat reversal.

Clear Sql Log Shipping History Detail

Starting transactional replication from a backup was introduced in SQL Server 2005. Some people may not realize that the backup used for starting does not have to be a full backup. You can start a subscriber with a backup or differential backup record. For example, I used to manage a team responsible for a 1.8TB OLTP database that was replicated across two mirror servers. Our general process for setting up replication for this database was to start by setting up log shipping. Overall, we were able to get to this point in the process in a reasonable time frame, thanks to the great work we did to optimize the backup and recovery processes. We then completed the replication setup the next day, knowing that the subscriber database was in sync.

The process to convert log shipping to transactional playback is quite simple. The following steps detail the process, starting from the point where log shipping is configured but not replication:

Most of these steps can be performed using the GUI in SQL Server Management Studio (SSMS). However, to create the subscription in the publisher in step 9, you must use the sb_addsubscription stored procedure because the GUI does not support the options required to start the subscriber from a backup. The sp_addsubscription stored procedure in Listing 1 creates a subscription for the TwoTBDatabase database on the SQLSrv02 server.
