Description
Creating the tanium and tanium_archive databases through the Tanium Server installer program or using the database create SQL scripts requires Sysadmin-level permissions. Once the databases have been created, the Tanium Server and Apache services must be configured to execute under an account that holds at least the dbo role on both databases. Post-installation, if the account used to configure the Tanium Server services to access the remote SQL database server holds only the Database Owner role, rather than the sysadmin role, consider granting this account the View Server State permission on the SQL Server. While it is not strictly necessary, this dynamic management view enables the Tanium Server to access data faster than the dbo role alone.
