Resolving The Problem

Steps to help resolve Synchronization problems
  1. What is the state of the node(s)? (check the administrative console)
Unknown or unavailable
  • 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.
       
Not synchronized, continue to step 2.
 
  1. 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. Continue to step 3 if problem is not resolved
       
  2. If you just enabled security, were all WebSphere Application Server processes (dmgr, nodes, appservers) recycled enabled?
    • Yes, continue to step 4.
    • No, recycle all processes then attempt to synchronize the node with the syncNode command. If the problem continues, go to step 4.
  3. 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
    • Yes, see this technote.
    • No, go to the next step.
       
What to do next?

If the preceding troubleshooting steps did not solve your problem, see the MustGather for synchronization problems to continue investigation.
