Steps to help resolve Synchronization problems
What is the state of the node(s) ? Check if the status is unknown or unavailable in the WebSphere administrative console.
Is the nodeagent running?
  • Yes, this is a discovery problem not a synchronization problem, see discovery TroubleShooting
  • No, start the nodeagent, this process is required for synchronization to work.
Is the "filetransfer" application installed and running? Go to Applications > Enterprise Applications in the administration console to view installed and running applications,
  • If not installed, install it.
  • If stopped, start the "filetransfer" application.
If you just enabled security, were all of the WebSphere Application Server processes (dmgr, nodes, appservers) that were  enabled, recycled ?
  • Yes, continue to the next step
  • No, recycle all processes then with the dmgr process up, and the nodeagent process down, attempt to synchronize the node with the syncNode command.
Do you see the following error within the NodeAgent SystemOut.log file ?

ADMD0012E: Unable to initialize the transport of type: TCP
ADMS0012E: Unable to create administrative client connection:
com.ibm.websphere.management.exception.AdminException: Admin client connection to deployment manager is unavailable
What to do next?
If the preceding troubleshooting steps did not solve your problem, see the MustGather for synchronization problems to continue investigation.
