The following list summarizes the steps required to connect from ArcGIS to a Dameng database:
- Install and configure the DM client on your ArcGIS client machines.
- After the DM client is configured on all ArcGIS client machines, create a database connection.
- To publish ArcGIS Server web services that reference the data in the Dameng database, register the database connection file with your ArcGIS Server sites.
Install the DM client
A DM client is needed on all ArcGIS client machines that will connect to Dameng.
You can download the DM client from Dameng Customer Support. Follow the instructions provided by Dameng to install the DM client. If you do not have the privileges to install software on the machines where ArcGIS clients are running, you'll need to have your IT department install the DM client for you.
If you do not have the privileges to install software on the machines where ArcGIS clients are running, you'll need to have your IT department install and configure the DM client for you.
Connect to the database
You can use the Database Connection dialog box in ArcGIS Pro to connect to the database, as described below.
Alternatively, you can run the Create Database Connection tool in ArcGIS Pro or use Python to run the Create Database Connection command from an ArcGIS Server machine to create a database connection file (.sde) that connects to the database.
To use the database connection file with ArcGIS Server, you must save user information with the connection file.
Tip:
Ensure the account used for the connection has the appropriate privileges in the database and on the data that the account needs to access. See Privileges for using ArcGIS with Dameng for more information.
Follow the steps below to connect to a Dameng database using the Database Connection dialog box in ArcGIS Pro.
- Open the Catalog pane in ArcGIS Pro.
- Right-click Databases and click New Database Connection.
- Choose Dameng from the Database Platform drop-down list.
- In the Data source text box, type the name of the server where Dameng is installed.
- Provide a valid username and password in the User name and Password text boxes, respectively.
- Optionally, uncheck Save user name and password if you prefer not to save your login information as part of the connection.
Doing this can help maintain the security of the database. However, if you do this, you will be prompted to provide a username and password every time you connect.
Note:
Save user name and password must be checked for connection files that you register with an ArcGIS Server site and to search ArcGIS Pro to locate data accessed through this connection file.
- Type a name for the connection file in the Connection File Name field.
As you provide connection information, a default name is created. You can use the default, or type a more descriptive file name.
This is the name that will appear in the Catalog pane and view, and the name of the .sde file stored on disk.
- If Dameng communicates over a nondefault port, expand the Additional Properties section, choose tcp_port from the Property drop-down menu, and type the port in the Value field.
- Click OK to create the connection file.
The Database authentication option is selected for the Authentication Type value. Operating system authentication is not supported.
A database connection appears under Databases in the Catalog pane, and a connection file (.sde) is created in the ArcGIS Pro project directory.
Register the database with ArcGIS Server
If you want web services to use the data in the Dameng database, register the database with your ArcGIS Server sites.
You can use the database connection file you created to register the database with ArcGIS Server from the Manage registered data stores pane in ArcGIS Pro or from ArcGIS Server Manager.
