SSISDB catalogs are the relevant part working with the SSIS (SQL Server Integration Services) projects that have applied to the Integration Services Server.
User access the SSISDB catalog in management studio by connecting SQL Server database engine then expands the Integration Services Catalogs node in Object Explorer. You can carry projects that contain packages to an Integration Services Server only after designing and testing packages in SQL Server data tools. The SQL Server must have catalog. The SQL Server 2012 doesn’t create catalog automatically. Create catalog first by manual procedure.
1. Open SSMS 2. Connect to SQL Server Database Engine 3. Expand the Server node from the Object Explorer, right click on Integration Services Catalog then create catalog. 4. Click on the Enable CLR Integration (catalog uses CLR stored procedures). 5. To run SQL Server instances each time click on the Enable automatic execution of Integration Services stored procedure at SQL Server startup. Stored procedure maintains the operation state for the catalog. It verifies if any packages running or not and when SSIS server goes down. 6. Enter password then click on OK button. 7. The encryption for catalog used by database master key which is protected by password. Save the password.
