R components as described here: Set up SQL Server R Services (In- Database). For issues related to Microsoft R Server on other platforms, see Microsoft R Server Release Notes and Run Microsoft R Server for Windows. Important changes from pre- release versions If you installed any pre- release version of SQL Server 2. SQL Server 2. 01. RTM versions. These changes include both the options available in the SQL Server setup wizard and post- installation steps. Warning. New installation of any pre- release version of R Services (In- Database) is no longer supported. We recommend that you upgrade as soon as possible. The post- configuration installation script is provided solely to help customers uninstall pre- release versions. If you install or upgrade servers that are not connected to the Internet, you must download an updated version of the R components manually before beginning the refresh. For more information, see Installing R Components without Internet Access. If you are using SQL Server 2. R components are automatically installed. As of December 2. R components on a faster cadence than the SQL Server release cycle, by binding an instance of R Services to the Modern Software Lifecycle policy. For more information, see Use Sql. Bind. R to Upgrade an Instance of SQL Server R Services. Support for slipstream upgrades. Slipstream setup refers to the ability to apply a patch or update to a failed instance installation, to repair existing problems. The advantage of this method is that the SQL Server is updated at the same time that you perform setup, avoiding a separate restart later. In SQL Server 2. 01. SQL Server Management Studio by clicking Tools, and selecting Check for Updates. If the server does not have Internet access, be sure to download the SQL Server installer. You must also separately download matching versions of the R component installers before beginning the update process. For download locations, see Installing R Components without Internet Acccess. This is by design, for surface area reduction. For more information about using R Services in an Always On availability group, see Always On Availability Groups: Interoperability. The replica could be created using either replication or log shipping. Launchpad service cannot be started. There are several issues that can prevent Launchpad from starting. To install R Services (In- Database), the drive where the feature is installed must support creation of short file names using the 8dot. If the volume where you are installing R Services (In- Database) does not support the short filenames, the processes that launch R from SQL Server might not be able to locate the correct executable and the SQL Server Trusted Launchpad will not start. You must then provide the short name for the working directory in the R Services configuration file. To enable 8dot. 3 notation, run the fsutil utility with the 8dot. After the 8dot. 3 notation is enabled, open the file RLauncher. In a default installation, the file RLauncher. C: \Program Files\Microsoft SQL Server\MSSQL1. MSSQLSERVER\MSSQL\Binn. Make a note of the property for WORKING. If you experience this issue, please install one of the following: The account that runs Launchpad has been changed or necessary permissions have been removed. By default, SQL Server Trusted Launchpad uses the following account on startup, which is configured by SQL Server setup to have all necessary permissions: NT Service\MSSQLLaunchpad. Therefore, if you assign a different account to the Launchpad or the right is removed by a policy on the SQL Server machine, the account might not have necessary permissions, and you might see this error: ERROR. If this happens, Launchpad can no longer connect to SQL Server, and R Services will be unable to function. To correct the problem, ensure that the group SQLRUser. Group has the system right Allow log on locally. For more information, see Configure Windows Service Accounts and Permissions. Error: Unable to communicate with the Launchpad service. If you install R Services and enable the feature, but get this error when you try to run an R script, it might be that the Launchpad service for the instance has stopped running. From a Windows command prompt, open the SQL Server Configuration Manager. For more information, see SQL Server Configuration Manager. Right- click SQL Server Launchpad for the instance where R Services is not working, and select Properties. Click the Service tab and verify that the service is running. If it is not, change the Start Mode to Automatic and click Apply. Typically, restarting the service enables R scripts. If it does not, make a note of the path and arguments in the Binary Path property. Review the rlauncher. Ensure that the Windows group used by Launchpad has the ability to connect to the SQL Server instance, as described in the previous section. Restart the Launchpad service if you make any changes to service properties. Do not create a side- by- side installation using another version of R or other releases from Revolution Analytics. The language identifier used for the R components must be the same as the SQL Server setup language being installed, or the Next button is disabled and you cannot complete setup. For more information, see Installing R Components without Internet Access. Unable to launch runtime for R script R Services (In- Database) creates a Windows users group that is used by the SQL Server Trusted Launchpad to run R jobs. This user group must have the ability to log into the instance that is running R Services in order to execute R on the behalf of remote users who are using Windows integrated authentication. In an environment where the Windows group for R users (SQLRUsers) does not have this permission, you might see the following errors: When trying to run R scripts: Unable to launch runtime for 'R' script. Please check the configuration of the 'R' runtime. An external script error occurred. Unable to launch the runtime. Errors generated by the SQL Server Trusted Launchpad service: Failed to initialize the launcher RLauncher. No launcher dlls were registered! Security logs indicate that the account, NT SERVICE\MSSQLLAUNCHPAD was unable to log in. Note. This limitation does not apply if you use SQL logins to run R scripts from a remote workstation. Remote execution via ODBC If you use a data science workstation and connect to the SQL Server computer to run R commands using the Revo. Scale. R functions, you might get an error when using ODBC calls that write data to the server. However, if these accounts cannot connect to the server, ODBC calls cannot be executed on your behalf. Run the following script. Be sure to edit the user group name, if you changed the default, and the computer and instance name. USE . Run script to deregister Windows user group and components before uninstalling previous components. If you installed a pre- release version of R Services (In- Database), you must first run run the script Registe. REext. exe with the /uninstall argument. By doing so, you deregister old components and remove the Windows user group associated with Launchpad. If you do not do this, you will be unable to create the Windows user group required for any new instances that you install. For example, if you installed R Services on the default instance, run this command from the directory where the script is installed: Register. RExt. exe /UNINSTALL. If you installed R Services on a named instance, specify the instance name after INSTANCE: Register. RExt. exe /UNINSTALL /INSTANCE: < instancename>. You might need to run the script more than once to remove all components. Important: The default location for this script is different, depending on the pre- release version you installed. If you try to run the wrong version of the script, you might get an error. CTP 3. 1, 3. 2, or 3. Additional steps are required to uninstall existing components. First, download an updated version of the post- installation configuration script from the Microsoft Download Center. The updated script supports de- registration of older components. Click the link and select Save As to save the script to a local folder. Rename the existing script, and then copy the new script into the folder where the script will be executed. RC0 The script file is located in this folder: C: \Program Files\Microsoft\MRO- for- RRE\8. R- 3. 2. 2\library\Revo. Scale. R\rx. Libs\x. Release versions (1. No script is needed to install or configure components. The script should be used solely for removing older components. The order of uninstallation of the R components is critical. Always uninstall Microsoft R Enterprise first. Then, uninstall Microsoft R Open. Uninstall any other version of Microsoft R Open. Finally, uninstall all other versions of Microsoft R Open. Step 4. Upgrade SQL Server. After all pre- release components have been uninstalled, restart the computer. This is a requirement of SQL Server setup and you will not be able to proceed with an updated installation until a restart is completed. Problems uninstalling older versions of RIn some cases, older versions of Revolution R Open or Revolution R Enterprise are not completely removed by the uninstall process. To upgrade to the RC3 version of Microsoft R Server, you must first uninstall using SQL Server 2. RC2 setup, and then reinstall using SQL Server 2. RC3 setup. This upgrades the instance of R Services (In- Database) to RC3; no additional configuration is necessary. For additional issues related to Microsoft R Server, see Microoft R Server Release Notes.
