Upgrading to Worklight 6.2

Question

I am facing issue with upgrading to Worklight 6.2. Please find the error below:

ERROR: transport error 202: bind failed: Address already in use
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [../../../src/share/back/debugInit.c:750]
FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197)

Thanks in advance

Answer 1

I guess you see this when starting your 6.2 server? It's because you have your 6.1 server still running. The clash on the dt_socket will cause the JVM to exit very early in startup.

You may run them both by adjusting the ports in one of them.

The dt_socket is specified in the server's jvm options:

      -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=10777

the remaining ports are specified in the server.xml

Answer 2

We can solve the problem without restarting your system.

Just type this in your commande line ( Linux, Mac OS) to look for process Id Worklight is using and kill it. Then go back to your eclipse and start your server. I'll work like a charm. Here the commande Line :

ps -A | grep worklight
kill -9 57184

(57184) : is the process Id, for my case I found 2 processes so killed the both.
