WLSTException: Error occured while performing connect : Error getting the initial context. There is no server running - weblogic

Question

Hii I am facing issue while connecting to weblogic server. The command i used to connect to it is as follows:
java -Dweblogic.security.SSL.ignoreHostnameVerification=true -
Djava.security.egd=file:/dev/./urandom -DUseSunHttpHandler=true -
Djava.net.preferIPv4Stack=true -Djava.awt.headless=true -
Dsun.jnu.encoding=ISO-8859-1 -Dfile.encoding=ISO-8859-1 weblogic.WLST
<path>/weblogic_configuration_domain_update.py <path>/weblogic-
domain.properties
It gives following error:
javax.naming.CommunicationException [Root exception is
java.net.ConnectException: t3://<IP>:<port>: Destination
unreachable; nested exception is: java.net.ConnectException: Connection
refused; No available router to destination]
Problem invoking WLST - Traceback (innermost last):
File "/<path>/weblogic_configuration_domain_update.py", line 134, in ?
File "<iostream>", line 22, in connect
File "<iostream>", line 648, in raiseWLSTException
WLSTException: Error occured while performing connect : Error getting the
initial context. There is no server running at t3://<IP>:<port>
Please let me know is there any way to resolve this issue. Thank you in advance.

Answer 1

you have to insert the correct values in the script: weblogic_configuration_domain_update.py
for example: connect(t3://thelisteingadressofthehost.network.com:thelisteningportoftheAdminServer)
and be sure which protocol you are using t3 or t3s...
