I have been playing with the new SQL Server on Linux command line tools

http://smooth1.co.uk/sqlserver2017/LINUX_CMD_TOOLS.html

Very nice that sql-scripter has an option to limit output to a given SQL Server Version and even better Edition although did find an issue with this option and will be providing feedback to Microsoft.

SQL Server – Changing Recovery Model from Full to Bulk Logged whilst a Tranasction is active.

Posted: May 10, 2017 | Author: | Filed under: Microsoft SQL Server, Microsoft SQL Server 2016, Uncategorized | Tags: , , | Leave a comment

If have a SQL Server database and change the Recovery Model from Full to Bulk Logged whilst a transaction is open what happens?

If the ongoing transaction which was started under Recovery Model Full does an operation which can be minimally logged what happens?

Does the operation become minimally logged which then means the VLF is tagged as a minimally logged logfile which then does not allow certain operations e.g. restores from the next log backup with STOPAT.

We test with STOPAT and also use fn_dump_dblog to see exactly what ends up in the log backup and how we can identify minimally logged operations in a log backup file.

In SQL Server 2016 we have database scoped parameters.

With an AlwaysOn Availability Groups we can have different database scoped parameter values on the primary compare to the secondaries.

How does this work with an Always On Availability Group failover ?
