Stash is now known as Bitbucket Server.
See the

Unknown macro: {spacejump}

of this page, or visit the Bitbucket Server documentation home page.

This page describes how to connect Stash to a Microsoft SQL Server database. 

The overall process for using a SQL Server database with Stash is:

  • Install SQL Server where it is accessible to Stash.
  • Create a database and user on the SQL Server server for Stash to use.
  • Install Stash on Windows, or on Linux or Mac.
  • Either:
    • at Stash install time, run the Setup Wizard to connect Stash to the SQL Server database, or
    • at a later time, migrate Stash to the SQL Server database.

It is assumed here that you already have SQL Server installed and running. SQL Server documentation is available at http://msdn.microsoft.com/en-us/library/bb545450.aspx.

See Supported platforms for the versions of SQL Server supported by Stash.

1. Prerequisites

Back up your current database

If you are migrating your data from the internal Stash database, back up the Stash home directory.

If you are migrating your Stash data from a different external database, back up that database by following the instructions provided by the database vendor before proceeding with these instructions.

See Data recovery and backups.

Create the SQL Server database

Before you can use Stash with SQL Server, you must set up SQL Server as follows:

StepNotes
Create a databasee.g. stash. Remember this database name for the connection step below.
Set the collation typeThis should be case-sensitive, for example, 'SQL_Latin1_General_CP1_CS_AS' (CS = Case Sensitive).
Create a database usere.g. stashuser. This database user should not be the database owner, but should be in the db_owner role. See SQL Server Startup Errors. Remember this database user name for the connection step below.
Set database user permissionsThe Stash database user has permission to connect to the database, and to create and drop tables, indexes and other constraints, and insert and delete data, in the newly-created database.
Enable TCP/IPEnsure that TCP/IP is enabled on SQL Server and that SQL Server is listening on the correct port (which is 1433 for a default SQL Server installation). Remember this port number for the connection step below.
Check the authentication modeEnsure that SQL Server is operating in the appropriate authentication mode. By default, SQL Server operates in 'Windows Authentication Mode'. However, if your user is not associated with a trusted SQL connection, 'Microsoft SQL Server, Error: 18452' is received during Stash startup, and you will need to change the authentication mode to 'Mixed Authentication Mode'.
Check that SET NOCOUNT is offEnsure that the SET NOCOUNT option is turned off. You can do that in SQL Server Management Studio as follows:
  1. Navigate to Tools > Options > Query Execution > SQL Server > Advanced. Ensure that the SET NOCOUNT option is cleared.
  2. Now, go to the Server > Properties > Connections > Default Connections properties box and clear the no count option.

Note that Stash will generally require about 25–30 connections to the database.

Here is an example of how to create and configure the SQL Server database from the command line. When Stash and SQL Server run on the same physical computer (accessible through localhost), run the following commands (replacing stashuser and password with your own values):

SQL Server> CREATE DATABASE stash
SQL Server> GO
SQL Server> USE stash
SQL Server> GO
SQL Server> ALTER DATABASE stash SET READ_COMMITTED_SNAPSHOT ON
SQL Server> GO
SQL Server> ALTER DATABASE stash COLLATE SQL_Latin1_General_CP1_CS_AS
SQL Server> GO
SQL Server> SET NOCOUNT OFF
SQL Server> GO
SQL Server> USE master
SQL Server> GO
SQL Server> CREATE LOGIN stashuser WITH PASSWORD=N'password', DEFAULT_DATABASE=master, CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF
SQL Server> GO
SQL Server> ALTER AUTHORIZATION ON DATABASE::stash TO stashuser
SQL Server> GO

This creates an empty SQL Server database with the name stash, and a user that can log in from the host that Stash is running on who has full access to the newly created database. In particular, the user should be allowed to create and drop tables, indexes and other constraints.

2. Connect Stash to the SQL Server database

You can now connect Stash to the SQL Server database, either:

  • when you run the Setup Wizard, at install time,
  • when you wish to migrate to SQL Server, either from the embedded database or from another external database.

When running the Setup Wizard at install time:

  1. Select External at the 'Database' step.
  2. Select SQL Server for Database Type.
  3. Complete the form. See the table below for details.
  4. Click Next, and follow the instructions in the Stash Setup Wizard.

When migrating to SQL Server:

  1. Click Administration and then Database (under 'Settings').
  2. Click Migrate database.
  3. Select SQL Server for Database Type.
  4. Complete the form. See the table below for details.
  5. Click Start Migration.
Hostname

The host name or IP address of the computer running the database server.

PortThe TCP port with which Stash can connect to the database server. The default value of 1433 is the default port that SQL Server runs against. You can change that if you know the port that your SQL Server instance is using.
DatabaseThe name of the database that Stash should connect to.
UsernameThe username that Stash should use to access the database.
PasswordThe password that Stash should use to access the database.
