Because the cluster_interconnects parameter is set incorrectly in the database instances on Exadata, one or more of the instances can be closed with the “kjzdattdlm: Can not attach to DLM” error. The same problem can be seen in ASM instances.

It is possible to see the following errors in the trace file specified in the error:
