Each execution of Setup creates log files are created with a new timestamped log folder at %programfiles%\Microsoft SQL Server\120\Setup Bootstrap\Log\. The time-stamped log folder name format is YYYYMMDD_hhmmss. When Setup is run in an unattended mode, the logs are created at % temp%\sqlsetup*.log. All files in the logs folder are archived into the Log*.cab file in their respective log folder.
A typical Setup request goes through three execution phases:
Global rules text
In each phase, Setup generates detail and summary logs with additional logs created as appropriate. Setup is called at least three times per user-requested Setup action.
Datastore files contain a snapshot of the state of all configuration objects being tracked by the Setup process, and are useful for troubleshooting configuration errors. XML file dumps are created for datastore objects for each execution phase. They are saved in their own log subfolder under the time-stamped log folder, as follows:
The following sections describe SQL Server Setup log files.
This file shows the SQL Server components that were detected during Setup, the operating system environment, command-line parameter values if they are specified, and the overall status of each MSI/MSP that was executed.
The log is organized into the following sections:
An overall summary of the execution
Properties and the configuration of the computer where SQL Server Setup was run
SQL Server product features previously installed on the computer
Description of the installation version and installation package properties
Runtime input settings that are provided during install
Location of the configuration file
Details of the execution results
Rules specific to the installation scenario
Location of the rules report file
It is located at %programfiles%\Microsoft SQL Server\120\Setup Bootstrap\Log\.
To find errors in the summary text file, search the file by using the "error" or "failed" keywords.
Detail.txt is generated for the main workflow such as install or upgrade, and provides the details of the execution. The logs in the file are generated based on the time when each action for the installation was invoked, and show the order in which the actions were executed, and their dependencies.
It is located at %programfiles%\Microsoft SQL Server\120\Setup
If an error occurs during the Setup process, the exception or error are logged at the end of this file. To find the errors in this file, first examine the end of the file followed by a search of the file for the "error" or "exception" keywords.
The MSI log files provide details of the installation package process. They are generated by the MSIEXEC during the installation of the specified package.
Types of MSI log files:
The MSI log files are located at %programfiles%\Microsoft SQL Server\120\Setup Bootstrap\Log\<YYYYMMDD_HHMM>\<Name>.log.
At the end of the file is a summary of the execution which includes the success or failure status and properties. To find the error in the MSI file, search for "value 3" and usually the errors can be found close to the string.
The configuration file contains the input settings that are provided during installation. It can be used to restart the installation without having to enter the settings manually. However, passwords for the accounts, PID, and some parameters are not saved in the configuration file. The settings can be either added to the file or provided by using the command line or the Setup user interface. For more information, see Install SQL Server 2014 Using a Configuration File.
