Verify WMI for MS Cluster issues

In a cluster environment, WMI is often used to share information and notification within the nodes. Some of the cluster issues/error due to the WMI is as listed below:

“RPC Server Unavailable” error.
Access is Denied.
The computer ‘Node1’ could not be reached.
Failed to retrieve the maximum number of nodes for ‘{0}’.
The computer does not have the Failover Clustering feature installed. Use Server Manager to install the feature on this computer.
Note: first confirm you have installed the Failover Clustering feature on this node

In above case we need to make sure that the WMI is working fine and this can be confirmed following the steps listed below:
Make sure that the WMI service is up and firewall settings.

1. Launch CMD
2. Type “WBEMTest” (without quotes”).
3. The Windows Management Instrumentation Tester will launch
4. Select Connect
5. Namespace: Root\MSCluster
6. Select Connect and if you see more options available, it means you are connected and WMI is working
7. Click on Query and enter SELECT * from MSCluster_Resource to confirm (any error shown represents WMI issue).

IBM DB2 error SQL5005C during server startup.

Upon windows server hosting DB2 reboot you will get an error message “SQL5005C”. This actually refers to “The operation failed because the database manager failed to access either the database manager configuration file or the database configuration file.” This is due to DB2 database utility (such as db2start, db2icrt, restore, or many others) requires that the database manager write to or read from either the database manager configuration file or the database configuration file, and the database manager was unable to access the configuration file.

This is fixed by performing the below steps:

1. Log in to the machine as system administrator.
2. Remove the db2systray by performing the following steps:
a. Windows Start –> All Programs –> IBM DB2 –> Command Line Tools –> Command Window Administrator.
b. db2systray -clean
3. Log off and log in to the machine.
