Abstract: CLIENTS CAN NOT CONNECT to an ORACLE PARALLEL SERVER NODE
SYMPTOM:
Client sessions can no longer connect to one of the nodes in the database, and/or
some rows or tables cannot be accessed from the other nodes.
The node to which the client sessions can no longer connect cannot see the shared
storage when viewing the drives with the NT Disk Administrator.
This node had been up and running OK.
This scenario has occurred without rebooting this node.
PROBLEM ISOLATION AIDS:
IBM Netfinity Cluster Enabler Software
FIX:
The action to take depends on the state of the OracleServiceOPSn service on the node that
clients can no longer connect to. "n" will be the number of the database instance so the actual
service name will be something like OracleServiceOPS1.
DETAILS:
A hardware failure may have occurred that prevents access to the shared storage on this node.
If this has occurred, the database instance on this node may behave in one of two ways:
