Default Ports Used by the Denodo Platform Modules

The table below lists the TCP/IP port numbers that each module of the Denodo Platform listens for incoming connections.

These are the default port numbers. They can be changed during the installation process or later, in the administration tool of each module.

Default TCPIP port numbers opened by the Denodo Platform modules
Server Default Port
Virtual DataPort and ITPilot Wrapper Server
Server ports (for Virtual DataPort administration tools and JDBC clients) 9999 and 9997
ODBC port 9996
Shutdown port 9998
ITPilot Browser Pool
Server ports 6001 and 6003
Shutdown port 6002
Initial Microsoft Internet Explorer browser port


The Browser Pool listens to this port to communicate with the first opened browser. The consecutive ascending port numbers will be used when additional browsers are requested.

For example, if the size of the Browser Pool is set to 30, the Browser Pool will listen in the port range from 6001 to 6030.

ITPilot Verification Server
Server ports 7001 and 7003
Shutdown port 7002
ITPilot PDF Conversion Server
Server port 8448
Aracne Server
Server port 11000 and 10998
Shutdown port 10999
Aracne Index / Search Engine Server
Server ports 9000 and 8998
Shutdown port 8999
Scheduler Server
Server port 8000 and 7998
Shutdown port 7999
Denodo Platform Web container (Scheduler, ITPilot and Aracne Administration Tools, Virtual DataPort Web services, Information Self Service Tool and Diagnostic & Monitoring Tool)
Web container port (for http/https requests) 9090 (http) and 9443 (https)
Shutdown port 9099
JMX port (for monitoring tools) 9098 and 9097

Almost all Denodo servers use two ports to listen to connections. Both are necessary and if the server is behind a firewall, both need to be opened in the firewall so the client applications can successfully connect to both.

If Denodo runs behind a firewall, open the following ports in the firewall:

  • 9999 and 9997: to allow connections from JDBC clients and the administration tool of Virtual DataPort.
  • 9996: to allow connections from ODBC clients of Virtual DataPort.
  • 9090: to allow connections from client applications/browsers to the web applications and web services.

The other ports do not need to be opened on the firewall because they are accessed locally. For example, the Scheduler administration tool connects to the Scheduler server but because the administration tool and the server run on the same machine, the firewall does not intercept the network traffic between them.
