Initialization of the Dynamic Link Library
NM.DLL Failed
If this failure occurs, stop the currently running OracleCMService and
OracleNMService. Restart the OracleNMService, then the OracleCMService.
From Administrative Tools, open the Services screen. Locate each service in
the displayed list, highlight it, then stop it. Finally, highlight the service and
restart it.
Troubleshooting Node-to-Node
Connectivity Problems
Nodes Are Unable to Communicate with Each Other
■ Check the Windows 2000 Advanced Server event logs for errors.
■ Check the OracleCMService error log for information. The default
location for the error log is C:\compaq\ops\cmsrvr.log. If not found in
the default location, look in the same directory in which the OSDs were
installed.
■ Verify the connections and accessibility of the cluster components.
Refer to the “Basic Troubleshooting Tips” section in this chapter.
■ The cluster interconnect must be on a separate subnet than the client
LAN. Check this by viewing the IP addresses assigned to all
interconnect adapters and to all client LAN adapters.
■ If Compaq Insight Manager is loaded and configured, use it to check the
operation statistics and possible error messages for the interconnect
adapter installed in each cluster node.
When Using the Ethernet Cluster Interconnect
■ Make sure that the Ethernet cluster interconnect components (adapters,
cables, switches or hubs) are properly installed as specified in Chapter 5,
“Installation and Configuration.”
■ Make sure that the Ethernet cluster interconnect and the client LAN are
connected to different Ethernet switches or hubs.
■ Use the ping utility to test the Ethernet cluster interconnect connections.
For information about the ping utility, refer to “Verifying Cluster
Communications” in Chapter 5, “Installation and Configuration.”
■ Make sure that all Ethernet traffic not related to the Oracle data is using
the client LAN, not the cluster interconnect.
