openx 2.8.1 "Session ID is invalid" when using XMLRPC api + ruby openx gem

Question

Occasionally when accessing OpenX 2.8.1 via its XMLRPC api (using the ruby 'openx' gem), I will get this error message:

Session ID is invalid

I cannot find anything in OpenX's forums about this, nor via some Google searching.

I am starting to suspect that it is a bug or other issue in the ruby gem itself.

Has anyone else encountered such an error, and if so, what is the fix? It does seem to resolve itself after running OpenX's maintenance scripts.

Answer 1

In using OpenX with a JSP application, we've found that too long a period of inactivity between the application and OpenX will cause the OpenX to invalidate the session ID. Currently our application was unable to get itself a new session, our workaround has been a restart of the application.

Using OpenX 2.6 my server connection would time out after about 25 minutes. Not sure I could ever find a current reference for it, but it worked to track the connection time and simply re-establish the connection after a timeout.

def openx_connection
  return @connection if (@timeout && Time.now < @timeout) 
  OpenX::Services::Base.connection=nil   # clear any remaining connection
  OpenX::Services::Base.configuration = {
    'username'  => @username,
    'password'  => @password,
    'url'       => @url }
  @timeout = Time.now + 25.minutes
  @connection = OpenX::Services::Base.connection  # establish a new connection
end
