Managed Database Hosting And Data Warehousing

The data warehouse supports up to 2 TB of data, with timestamps for change tracking. The data warehouse stores data by automatically synchronizing data from the Configuration Manager site database to the data warehouse database. This information is then accessible from your reporting service point. Data synchronized to the data warehouse database is kept for three years. Periodically, a built-in task removes data that's older than three years.

The data warehouse database requires the use of SQL Server 2012 or later. The edition can be Standard, Enterprise, or Datacenter. The SQL Server version for the data warehouse doesn't need to be the same as the site database server.

Each hierarchy supports a single instance of this role, on any site system of the top-tier site. The SQL Server that hosts the database for the warehouse can be local to the site system role, or remote. The data warehouse works with the reporting services point installed at the same site. You don't need to install the two site system roles on the same server.

When you install the role, Configuration Manager creates the data warehouse database for you on the instance of SQL Server that you specify. If you specify the name of an existing database, Configuration Manager doesn't create a new database. Instead it uses the one you specify. This process is the same as when you move the data warehouse database to a new SQL Server.

Database name: Specify a name for the data warehouse database. Configuration Manager creates the data warehouse database with this name. If you specify a database name that already exists on the instance of SQL Server, Configuration Manager uses that database.

SQL Server port used for connection: Specify the TCP/IP port number used by the SQL Server that hosts the data warehouse database. The data warehouse synchronization service uses this port to connect to the data warehouse database. By default, it uses SQL Server port 1433 for communication.

Data Synchronization custom setting: Choose the option to Select tables. In the Database tables window, select the table names to synchronize to the data warehouse database. Use the filter to search by name, or select the drop-down list to choose specific groups. Select OK when complete to save.

The data warehouse point supports alternative credentials. Specify credentials that SQL Server Reporting Services uses to connect to the data warehouse database. Data warehouse reports don't open until you add credentials.

When you install the data warehouse, it synchronizes a set of default tables from the site database. These tables are required for data warehouse reports. While troubleshooting issues, you may want to stop synchronizing these default tables. Starting in version 2203, you can exclude one or more of these required tables from synchronization. To exclude tables from synchronization:

Unlike a move of the data warehouse database, this change results in a loss of the historic data you have previously synchronized at the primary site. It isn't supported to back up the database from the primary site and restore it at the CAS.

Under SQL Server Services, restart the SQL Server service. If SQL Server Reporting Services is also installed on the server that hosts the data warehouse database, restart Reporting Service services as well.

During the move, you need to stop services on your management servers, back up the database, restore the database, update the registry on management servers, update database tables, add new Logins, and modify User Mapping settings for Logins. For more information, see SQL Server documentation.

On the original SQL Server instance hosting the Reporting data warehouse database, use Microsoft SQL Server Management Studio to create a full backup of the database. The default name is OperationsManagerDW.

Use Microsoft SQL Server Management Studio to restore the Reporting data warehouse database. (In the previous step, you moved the database backup file to a local drive of the new SQL Server instance.) In this step, you can change the name of the database and choose the file location.

After moving the Operations Manager Reporting data warehouse database to a different SQL Server instance, you'll need to follow the steps below to reconfigure all management servers in the management group to reference the new computer name and instance. This requires modifying the registry, the configuration service configuration file, and several tables in the operational database. The steps are detailed in the How to configure Operations Manager to communicate with SQL Server.

On the reporting server, you'll need to change the connection string to reference the new computer name and instance of the SQL Server instance hosting the Reporting data warehouse database. The steps are detailed in the How to configure Operations Manager to communicate with SQL Server.

If an account hasn't existed before in the SQL instance in which you're adding it, the mapping will be picked up by SID automatically from the restored data warehouse database. If the account has existed in that SQL instance before, you receive an error indicating failure for that login, although the account appears under Logins. If you're creating a new login, ensure the User Mapping for that login and database are set to the same values as the previous login as follows:

Ensure that the health states of all management servers in the management group are Healthy. If the health state of any management server is Critical, open Health Explorer, expand Availability - , and then continue to expand until you can navigate to Data Warehouse SQL RS Deployed Management Pack List Request State. Check the associated events to determine if there's an issue accessing the data warehouse database.

a. Open the Event Viewer and navigate to Applications and Services Logs and Operations Manager.b. In the Operations Manager log, search for events with a Source of Health Service Module and a Category of Data Warehouse. If the move was successful, event number 31570, 31558, or 31554 should exist.c. If there's an issue accessing the data warehouse database, event numbers 31563, 31551, 31569, or 31552 will exist.

a. In the Operations console, select Monitoring.b. In the Monitoring workspace, navigate to Monitoring, Operations Manager, Health Service Module Events, and then to Performance Data Source Module Events.c. Search the Performance Data Source Module Events pane for events with a Date and Time that is later than the move.d. If there's a problem with the data warehouse database, events that have a Source of Health Service Module and an Event Number of 10103 should exist.
