Products

• Data Center Security Server Advanced

Issue/Introduction

You need to expand the number of concurrent users as API calls fail with a 500 Server Error when more than 4 calls are made.

Environment

DCS 6.10.3 and Higher

Resolution

We recommend adding the logout call to your API code.

In some use cases, you may need to increase the concurrent limit beyond the default of 5.

The maximum number of concurrent users in Symantec Data Center Security can be adjusted by modifying the server configuration settings to accommodate higher API traffic.

 

Configuration Procedure

To increase the user token limit, you must modify the application.properties configuration file located on the management server.

 

1. Navigate to the installation directory: C:\Program Files\Symantec\Symantec Data Center Security\Server\Management.
2. Open the application.properties file using a text editor with administrative privileges.
3. Append the following configuration line to the end of the file: 

   user.token.limit=50

4. Save your changes and close the editor.
5. Restart the "Symantec Data Center Security Management Server" service to apply the new parameters.

 

Recommendations and Limits

While development recommends a standard limit of 15 concurrent users, the value can be customized based on organizational requirements (e.g., set to 50 as shown in the example above).
