Usage Notes - MonitorPhysicalConfig

The MonitorPhysicalConfig function provides similar functionality to the PMPC MONITOR PHYSICAL CONFIG request. For information about this interface, see MONITOR PHYSICAL CONFIG.

Result Rows

Column Name Description
ProcId ID associated with a node.

This value is computed as the module number within a cabinet plus the cabinet number times 10000. For example, a node #123 on cabinet #4 would return an INTEGER value of 40123.

Status Status of the node associated with this record:
  • U = Up/online
  • D = Down/offline
  • S = Standby
A node is up (U) when it is:
  • Configured into the system
  • Online
  • Capable of actively performing tasks associated with normal Teradata Database activity

Down (D) represents all other potential states.

Standby (S) indicates the node is ready to join the configuration in place if another node goes down. When the node status is Standby, the SystemType, NetAUp, and NetBUp fields are not available and NULL or spaces will be returned.

CPUType Type of CPU installed in this node, for example: 'Pentium', 'PentPro', or 'Unknown'.
CPUCount Number of CPUs in this node.
SystemType Type of system running the Teradata Database software, such as 5650, 6700, or ‘Other’.

If all the nodes in the system are the same type, this field returns the type of the system.

If any of the nodes are of a different type, this field returns ‘Mixed’.

CliqueNo Clique number of the node.
NetAUp Status of the BYNETs (if there are more than two, the first two) on a system-wide basis:
  • U = All node BYNETs are up/online.
  • D = One or more node BYNETs is down/offline.
  • “” = A temporary condition where the BYNET data is not available.
NetBUp Status of the BYNETs (if there are more than two, the first two) on a system-wide basis:
  • U = All node BYNETs are up/online.
  • D = One or more node BYNETs is down/offline.
  • “” = A temporary condition where the BYNET data is not available.
PhyMemory Size of the physical memory of the node in MBs.

Example: Using MonitorPhysicalConfig

SELECT t2.* FROM TABLE (MonitorPhysicalConfig()) AS t2;

 *** Query completed. One row found. 9 columns returned.
 *** Total elapsed time was 1 second.
