When I tried to start nodeagent and app server of websphere, it said in /apps/WebSphere/Profiles/Node-stage01-04/logs/nodeagent/SystemErr.log:

[06/05/11 00:17:36:556 BST] 0000000a SystemErr     R com.ibm.ws.exception.RuntimeError: com.ibm.ws.exception.RuntimeErro
r: Unable to start the CoordinatorComponentImpl

Then, I found this page:http://www-01.ibm.com/support/docview.wss?uid=swg21293285

I tried to look for RMM jar file, but failed. There’s no this file under install_root.

Then, I re-run the startNode.sh for twice, magiccally, this resolved itself. Now the nodeagent and app server are both booting themselves ok.

Weird! Read more…
