This article describes how to connect an M&M Central to Microsoft SQL Server instance.
Setting up the Database
Men & Mice requires that a blank database is created on the database server, with the collation SQL_Latin1_General_CP1_CS_AS, and a login (Windows or SQL server authenticated) that has db_owner access to that database and an effective default schema of mmCentral.
The attached CreateDatabase.sql is a suggestion for the database and database server setup. Please note that this script also configures the SQL server itself, which is unnecessary and undesirable in most cases. Therefore, review the script with your database administrator and only run appropriate parts of it.
Before you run the script please go through the script and change the necessary entries accordingly. This includes path strings (default C:/Data) and very important also the password, which is set by default to "1234" in the script!
Please note that the script is preconfigured for an 8 core processor machine, i.e. as a best practice we recommend to create for each processor core one temp file. If you have only a two core machine please comment out the last 6 temp file creation commands in the script.
Subsequent it will create an empty database with the name "mmsuite" and the following collation
It will also create a user mmSuiteDBUser with the password that you have inserted in the script.
For details please have a look into the CreateDatabase.sql script.
Configuring the connection parameters
If it's a dedicated server please don't forget to enable the TCP/IP protocol with the SQL Configuration Manager:
- Download the M&M mmdbprefs.exe tool: ftp://ftp.menandmice.com/pub/mmsuite/misc/dbprefstool/mmdbprefs.exe
- Copy the mmdbprefs.exe into the data directory of the M&M Central.
c:\Program Files\Men and Mice\Central\Data
c:\Program Files(x86)\Men and Mice\Central\Data
or on Windows Server 2008 R2 and later
c:\ProgramData\Men and Mice\Central
- Then start the mmdbprefs.exe tool by double-click. It will ask you a few questions
For MS SQL Server please enter "2" and confirm with Enter.
Please type in the database server in the following format:
Confirm your input by pressing the Enter key.
Finally you need to provide the password (it will not be displayed in the shell) and then press Enter.
Now the preferences.cfg file in the data directory contains beside the fingerprint of Central (i.e. the "password" XML-tag) four additional XML tags: database, databaseserver, databaseusername and databasepassword
The preferences.cfg file for normal user/password authentication should look like:
An example preferences.cfg file for the Windows Authentication method should look like (databaseusername tag must be present and the value attribute must be set to empty string):
Establishing a connection to Men & Mice Central
Since the database was freshly created you can now follow the normal installation procedure. Please see the installation guide and the user manual of the M&M Suite for further information.
Mirrored SQL Server instances
Men & Mice Central (v18.104.22.168 and above) can be made aware of mirrored instances of the database. In case a failover occurs, M&M Central will try to talk to the new principal server, i.e. the failover partner, if specified.
1. Change the databaseservername attribute in the preferences.cfg or rerun mmdbprefs.exe and provide the value:
Where "serverA" and "serverB" are the principal and mirror SQL servers, and "mmsuite" is the name of the database
2. If the machine running M&M Central does not have SQL Server installed, install the Microsoft SQL Server Native Client tools (http://www.microsoft.com/download/en/confirmation.aspx?id=16978)
