WebLogic Scripting Tool (WLST) is a command-line scripting environment that you can use to create, manage, and monitor WebLogic Server domains .

I recently encountered issue while connecting to WebLogic Server from WLST command connect(‘user’,’password’,’adminserver’)) remotely.

Issue: WLST connect from local machine (where WebLogic Server is running) is working fine where as connection from remote machine (WLST on remote machine) reported error. dumpStack() reported error Bootstrap to [IP/[IP]:[Admin Port] failed. It is likely that the remote side declared peer gone on this JVM

 

Command executed and error message is

Checks done 

1. Ensure that remote machine can access WebLogic Server (there is no firewall) : This worked for me and I was able to access WebLogic Console using IP and actual Hostname http://192.168.1.12:7001/console

 

Issue: In my case Machine running WebLogic Server had two host names

a) Actual Hostname – weblogichost.mydomain.com  and
b) Virtual Hostname – innowave21  (WebLogic Admin Server was configured to run on Virtual Name)

 

 

 

Fix: Ensure that client machine (from where WLST is being run), can resolve hostname mentioned in Listen Address of Admin Server (innowave21 in my case)

If not then add entry like below on hosts file of machine from where you are running WLST to connect to WebLogic Server

192.168.1.12   innowave21

 

Note: After adding entry in hosts file (or DNS server) for innowave21, I was able to connect using WLST.
