-> Error: The specified agent_id 1D58DD23-142C-498F-83AB-5077791B5781 or agent_type 1 do not form a valid pair for log shipping monitoring processing
-> Removing Log shipping on a database with AlwaysOn configured}

Environment

-> JBSAG1, JBSAG2 and JBSAG3 are part of a failover cluster without shared storage. Alwayson Availability group is configured between JBSAG1, JBSAG2 and JBSAG3. JBSAG1 is the current primary, JBSAG2 is the synchronous secondary and JBSAG3 is Asynchronous secondary. The database(s) that is part of Always on Availability group will have log shipping configured and its secondary will be JBSAG4.

-> AlwaysOn availability group is already configured. Below is the Availability group properties,

-> Transaction log backups will happen on AlwaysOn secondary as per the settings below.

-> This article will discuss how to configure log shipping. Please note that below steps for setting up Log shipping can be followed for “AlwaysOn Backup preferences” “Prefer Secondary”, “Secondary only”, “Primary” or “Any Replica”.

-> On AlwaysOn primary JBSAG1, right click JBDB database and click on properties. Click on “Transaction Log Shipping”,

-> Check “Enable this as a primary database in a log shipping configuration” and click OK.

-> Click “Backup Settings…”. Provide appropriate location where the backup should be placed,

-> Click on Schedule and set appropriate schedule for backup and click OK,

-> Click OK for “Transaction Log Backup Settings”. Click on “Add..” under “Secondary server instances and databases:”. In “Secondary Database Settings” connect to Log shipping secondary server instance.

-> Under “Initialize Secondary Database”, select appropriate option that suits better. In my case I will select first option, since my database is not that big.

-> Click on “Copy Files” and provide appropriate location where the files should be copied over. Select “Schedule” and change the schedule of copy job appropriately,

-> Click OK on the copy job. Click OK on “Secondary Database Settings” and then Click “OK” for “Transaction Log Shipping” on database properties.

-> On AlwaysOn synchronous secondary JBSAG2, right click JBDB database and click on properties. You may get below error if “Readable Secondary” is set to NO in Availability Group properties.

TITLE: Microsoft SQL Server Management Studio

Cannot show requested dialog.

ADDITIONAL INFORMATION:

Cannot show requested dialog. (SqlMgmt)

An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)

The target database, ‘JBDB’, is participating in an availability group and is currently not accessible for queries. Either data movement is suspended or the availability replica is not enabled for read access. To allow read-only access to this and other databases in the availability group, enable read access to one or more secondary availability replicas in the group. For more information, see the ALTER AVAILABILITY GROUP statement in SQL Server Books Online. (Microsoft SQL Server, Error: 976)

-> If you receive above error. Try changing “Readable Secondary” to Yes and try again.

-> On AlwaysOn synchronous secondary JBSAG2, right click JBDB database and click on properties. Click on “Transaction Log Shipping”, provide same settings for “Network path to backup folder” and Change the backup job schedule same as what was provided for log shipping settings in AlwaysOn primary JBSAG1.

-> Make sure it is blank for “Secondary server instances and databases:”. Click OK.

-> On AlwaysOn asynchronous secondary JBSAG3, right click JBDB database and click on properties. Click on “Transaction Log Shipping”, provide same settings for “Network path to backup folder” and Change the backup job schedule same as what was provided for log shipping settings in AlwaysOn primary JBSAG1.

-> Make sure it is blank for “Secondary server instances and databases:”. Click OK.

-> With this log shipping setup is complete. Below are the jobs that are created after the Log shipping setup,

-> You can try failover and failback to see if everything works fine. All these jobs can run on respective SQL Server instances irrespective of which SQL Server instance JBSAG1, JBSAG2 or JBSAG3 is Alwayson primary. There is no requirement to change any of these jobs to run on AlwaysOn primary only.
