Default SQL Server Configuration

This topic contains and refers to SQL Server 2019–specific information. If you have installed a different SQL Server version, you must search for your version-specific information at https://docs.microsoft.com.

The PTC Modeler installation program sets up a SQL Server 2019 Express instance named MODELER as part of Standalone and Server Only installations by default. SQL Server provides database storage and management services. In Model Explorer, databases are used to store, organize, and distribute models. For a list of all supported versions of SQL Server, see the Release Notes document.
The following table outlines SQL Server system and PTC Modeler databases following an installation:

Your SQL Server instance may contain additional databases that are used by programs and services other than PTC Modeler.
|
The SQL Server Express Edition 2019 provided with PTC Modeler has the following limitations:
• CPU support is limited to one socket and up to four cores
• 1GB of RAM for each SQL Server instance
• 10GB maximum database size
 |
If you have multiple SQL Server instances installed on one server, database names in each instance must be unique for the server.
|
While Express Edition is sufficient for Standalone PTC Modeler installations, these limitations can have a direct impact on performance for larger server deployments.
For more information on supported features for each SQL Server edition, refer to the following help topic:
Features Supported by the Editions of SQL Server 2019
If your production requirements exceed the capabilities of Express Edition, you should consider installing SQL Server Standard or SQL Server Enterprise.
To install PTC Modeler using a SQL Server instance other than the one provided with PTC Modeler, do the following:
1. Install and configure a SQL Server instance. For more information on supported SQL Server versions, refer to the PTC Modeler Release Notes document.
For more information on how to install and configure SQL Server, refer to the following SQL Server help topic:
Install SQL Server 2019
2. Run the PTC Modeler installation program, and in the Installation Wizard connect to your SQL Server instance:
◦ For Standalone, follow the instructions in Performing a Standalone installation.
◦ For Server Only, follow the instructions in Performing a Server Only installation.
3. Execute the adminscript_master.sql script on the master database of SQL Server instance using SQL Server Management Studio.
To execute a script in SQL Server Management Studio, do the following:
a. On the computer running the SQL Server instance, start SQL Server Managment Studio.
b. Connect to the SQL Server instance.
c. Click File, point to Open, then click File...
d. In the Open File dialog box, select the adminscript_master.sql script, then click Open.
The full path to the script is <<INSTALLDIR>>\Modeler\System\SQLScripts\adminscript_master.sql.
e. With the script open, select the master database from the drop-down list in the SQL Editor toolbar, then click Execute.
f. Confirm that the Query executed successfully message appears.
