When starting node, ADMU3007E is reported: Exception java.io.FileNotFoundException: /opt/IBM/WebSphere/AppServer/profiles/AppSrv01/config/cells/salld01Node01Cell/nodes/salld01Node01/servers/nodeagent/server.xml (there is no such file or directory )
I found it on the Internet and said that the startup location is wrong, but my file location is correct, the node is out of sync
Finally, there is no trick, add node operation
./addNode 132.42.43.168 8879 -username wasadmin -password wasadmin
After that, a new node name appeared on the console, but the previous server was still the first node. There is no way but to create a new server, and then re-hang the application to the new server
