|Tcat Server reached its End of Life in 2017. Contact your Customer Success Manager to determine options for managing, monitoring, or deploying your application.|
This page describes common problems and how you can troubleshoot them.
You can use Tcat Server to check memory usage, see which objects are in your session and how big they are, view deployment descriptors, view threads, and view JSPs and their generated code. You can view these details by clicking a server on the Servers tab and then navigating through the tabs that show the server details. To see details for a particular application on the server, click the Applications tab when viewing the server details, and then click the application name.
When servers are registered, they are registered with a specific IP address. If you are testing on a laptop with a wireless connection and you move from one location to another, your IP address might change, and the servers cannot communicate with Tcat Server. In this case, you must unregister and reregister the servers with the current IP address.
To manually unregister a server, you must delete its
webapps\agent\WEB-INF\truststore.jks file. The server then becomes available again for registering in another console.
Problem: My Newly Installed Tcat Server Instance is Running, but it Does not Appear in the Unregistered Group in the Console
If you are connected to a virtual private network (VPN), it can interfere with new Tcat Server instances appearing in the console. Disconnect from the VPN, restart the Tcat Server instance, and try again. You can verify that your Tcat Server agent is running by entering
http://<hostOrIPAddress>:<port>/agent in your browser, such as http://localhost:8080/agent if it’s on your local computer. If you get a message indicating the status of the agent, it’s running.
After you have registered your servers, you can reconnect to your VPN.
Problem: My Newly Installed Tcat Server Instance is Running and Appears in the Unregistered group in the Console, But I Can’t Register it
This can happen if you do not have an HTTP connector port set in the
conf\server.xml file in your Tomcat installation, such as if you’re just using the AJP port to connect via HTTPD. You must have an HTTP connector port configured so that Tomcat can communicate with Tcat Server.

Problem: I Want to Change Which Files can be Edited from the Files Tab when Viewing a Specific Server’s Details
The Files tab provides you with access to files on the local server as well as remote servers. To restrict or enable write access to a directory on a specific server, you modify the
agent/WEB-INF/spring-services.xml file on that server and add or remove directories from the
writeExcludes property in the
