Methods and systems for internally debugging code in an on-demand service environment

A remote debug session for a server group is provided. A server group including multiple servers that perform workload sharing receives a request to debug code executed at the server group. The code is executed on behalf of a client of a database associated with the server group. At least one of the servers of the group initiates a debugging session and establishes a communication connection with the client. The server group maintains the connection open with the client for the duration of the debugging session. Subsequent requests related to the debug session can be handled in a number of ways by the server group, and all communication to the client about processing the requests is through the connection.
