I Verify that all files created by Net8 Config Assistant were transferred properly to each respective node. I Verify the connections and accessibility of the cluster components. Refer to the "Basic Troubleshooting Tips" section in this chapter. I Verify that the OracleService is running. From the Services screen, scan the list of services and check to see if the OracleService is started. I Verify that the database links are properly set up on all nodes and that correct entries exist for all datafiles, including OPS_CMDISK. Refer to the Oracle8i Parallel Server Setup and Configuration Guide for further details.
