Migrate a Microsoft SQL Server Database
If the database server is Microsoft SQL Server 2012, 2014, or 2016, the Data Collector database can be migrated to a new
Microsoft SQL Server.
Steps
1. Back up the database on the original Microsoft SQL Server.
2. Set up a new Microsoft SQL Server and configure it to use mixed mode authentication (SQL Server and Windows
Authentication mode).
3. Perform a restore of the database on the new Microsoft SQL Server.
4. After the database is restored, create the required database user.
a. Create a database user named compmsauser, but do not assign the user to a schema .
b. Set the password of the compmsauser database user to the password it was assigned in the previous database.
● If you did not previously change the password, the default password is R3p0r!cty4sgs.
● If you do not remember the password or you want to use a different password, you must enter the new password
when you run the Change Data Source wizard in Step 6.
5. Run the following query on the compmsadb database:
sp_change_users_login 'update_one', 'compmsauser', 'compmsauser'
6. After the query finishes, use the Data Collector to change the data source to the new database.
NOTE:
If you changed the password, select the Use Custom Password checkbox and type the password in the
Custom Password field.
Uninstalling the Data Collector
On the server that hosts the Data Collector, use the Windows Programs and Features control panel item to uninstall the
Storage Manager Data Collector application.
Deleting Old Data Collector Databases
Delete the old Data Collector database if you have migrated the database to a different database server or if you have removed
the Data Collector from your environment.
Clean up a MySQL Database
Remove Unisphere Central data from the MySQL database and reinstall the Data Collector.
Steps
1. Enter the following SQL commands as an Admin user:
Drop Database compmsadb;
DELETE FROM mysql.user WHERE User = 'compmsauser';
DELETE FROM mysql.db WHERE user = 'compmsauser';
FLUSH PRIVILEGES;
2. Reinstall the Storage Manager Data Collector.
