Port number configuration
Review the default port numbers so that you can avoid port conflicts when you configure resources or assign port numbers to other applications.
If you configure a firewall, you must explicitly enable access to particular port numbers. You must also ensure that all Watson Explorer Content Analytics servers are inside the firewall.
| Port name | Port numbers | Where configured |
|---|---|---|
| Common communication layer (CCL) | 6002 | ES_INSTALL_ROOT/nodeinfo/es.cfg and ES_NODE_ROOT/master_config/nodes.ini on all servers |
| Data listener port | 6668 | To change this port, use the System view in the Watson Explorer Content Analytics administration console to configure your data listener application. |
| Embedded web application server: administration console and REST API for administration, non-SSL | 8390 | ES_INSTALL_ROOT/nodeinfo/es.cfg |
| Embedded web application server: administration console and REST API for administration, SSL | 9440 | ES_NODE_ROOT/master_config/admin/wlp/server.xml. You can also configure the SSL port when you configure security settings in the administration console. |
| WebSphere® Application Server: administration console and REST API for administration | 9081 or 80 | ES_INSTALL_ROOT/nodeinfo/es.cfg |
| Search server | 8394 | ES_INSTALL_ROOT/nodeinfo/es.cfg |
| Embedded web application server: enterprise search application, content analytics miner, and REST API for search, non-SSL | 8393 | ES_INSTALL_ROOT/nodeinfo/es.cfg |
| Embedded web application server: enterprise search application, content analytics miner, and REST API for search, SSL | 9443 | ES_NODE_ROOT/master_config/searchapp/wlp/server.xml. You can also configure the SSL port when you configure security settings in the administration console. |
| WebSphere Application Server: enterprise search application, content analytics miner, and REST API for search | 9081 or 80 | ES_INSTALL_ROOT/nodeinfo/es.cfg |
| HTTP server for the embedded web application server | 80 | HTTP_SERVER_ROOT/conf/http.conf on the search servers |
| HTTP server for WebSphere Application Server | 9081 | HTTP_SERVER_ROOT/conf/http.conf on the search servers |
| WebSphere Application Server administrative console | 9060 | On the search servers, if you use WebSphere Application Server |
| DB2 crawler | 6000, 6001, 6002, 60003, 50000 | On the crawler server |
| Anonymous or dynamic ports for CCL, file transfers (ESFTP), and index copy | 49152 to 65535 | On all servers |
| Apache Derby Network Server | 1527 | On the crawler server |
| Custom communication | 8890 | On the crawler server. The default listening port is undefined, which means the session obtains an available port. If you want to set a fixed port number, set the port property in the ES_INSTALL_ROOT/configurations/customcommunication /customcommunication.properties file. |
