Informational messages added for tempdb configuration in the SQL Server error log in SQL Server 2014 SP2

Summary
This update improves the supportability of SQL Server 2014 by adding informational messages for tempdb configuration to the SQL Server error log. After you install this update, an informational message that resembles the following is logged in the SQL Server error log at SQL Server startup:
The tempdb database has %ld data file(s).

Additionally, when there are multiple tempdb data files, if the tempdb data files do not have the same initial size or autogrowth size, an informational message that resembles the following is logged in the SQL Server error log:

The tempdb database data files are not configured to use the same initial size and autogrowth settings. To reduce potential allocation contention, the initial size and autogrowth of the files should be same.

More information
The equal sizing of data files is important because the proportional fill algorithm is based on the size of the files. If data files are created with unequal sizes, the proportional fill algorithm tries to use the largest file more for GAM allocations instead of spreading the allocations between all the files. This defeats the purpose of creating multiple data files.

This update helps you check whether you are following the best practices recommendations in the Working with tempdb in SQL Server 2005 TechNet article.

This update is included in the following service pack for SQL Server:
