Purpose

The DISPLAY CONFIG command is used to display the current values for information that can be specified by the CONFIG command.

Syntax



CP
Requests that Channel Processor configuration information be displayed.
NP
Requests that Network Processor configuration information be displayed.
XP
Requests that configuration information used by both Channel Processors and Network Processors be displayed.
NODETAIL
Requests that only values for configuration options intended for general use are to be displayed.
DETAIL
Requests that the values for configuration options not intended for general use are to be displayed.
This operand is intended for use in consultation with Teradata customer support personnel. The resulting information requires internal knowledge of TDP to properly interpret. Without such knowledge, misleading conclusions are probable. Time can be saved by heeding this recommendation.

Usage Notes

Information that may be specified by a CONFIG command but which was not, and has no default value, is not displayed.

General Information

The following information is always displayed:
  • The number of minutes between messages reminding that all communication has been lost with the database, as set by the CONFIG COMMLOST MSG INTERVAL command.

If 'CP' is specified nothing additional is displayed.

If 'NP' is specified the following information is displayed.

  • When configured, the database Logical-host id to be used if needed for the first NP started. This may not be the LHID that is being used by TDP if a CP started before an NP.
  • When configured, the name of the domain with which communication is to be established. This name consists of the rightmost labels of the network name defined to either the operating system local host or network Domain Name System (DNS) name established by the network administrator for Vantage. See Teradata┬« Tools and Utilities for IBM z/OS Installation Guide (B035-3128) for details on configuring network information.
  • When configured, the name of the operating system IP stack to be used.
  • The character set for the CONFIG DATABASE and DOMAIN operands, and the START IPADDR operand. Though this value currently may not be configured, it defaults to EBCDIC.
  • When configured, the name of the database with which communication is to be established. This name is the leftmost label of the network name defined to either the operating system local host or network Domain Name System (DNS) name established by the network administrator for Vantage. See Teradata┬« Tools and Utilities for IBM z/OS Installation Guide (B035-3128) for details on configuring network information.
  • How often a TDP3512 message is issued when an NP is attempting to establish communication with the database, if ENABLE NPCOMM DETAIL has been issued.

If 'XP' is specified nothing additional is displayed.

DETAIL Information

Nothing is added to the display if no options other than DETAIL are specified.

The following information is displayed if both the CP and the DETAIL operands are specified:
  • Whether communication protocol checksum processing is forced OFF, forced ON, or automatically adjusts to whether the database presents such checksums (AUTO).
  • The maximum number of consecutive communication protocol checksum violations before the CP is considered unusable. A value of zero indicates no threshold exists.
  • The maximum number of I/O buffers recommended for a channel transmission. This recommendation may not be the value used.
  • The maximum size of an I/O buffer recommended for channel transmission. This recommendation may not be the value used.
  • Whether or not CPU time used for CP processing is being recorded.
The following information may be displayed if both the NP and the DETAIL operands are specified:
  • When configured, the network port on the database associated with NPs.
  • Whether or not Transmission Unit (TU) summary information is recorded.
  • When configured, which versions of IP addressing will be used, as either IPv4 only, IPv6 only, or 'DUAL'.
  • When configured, the network IP transport mechanism to be used.
  • When configured, the name of the service that is associated with the network port on the database to be used.
  • That encapsulation checksum processing is ON, though this information might not be configured.
  • The maximum number of consecutive encapsulation checksum violations before the NP is considered unusable. A value of zero indicates no threshold exists.
  • The maximum number of I/O buffers recommended for a network transmission. This recommendation may not be the value used.
  • The maximum size of an I/O buffer recommended for network transmission. This recommendation may not be the value used.
  • Whether communication protocol checksum processing is forced OFF, forced ON, or automatically adjusts to whether the database presents such checksums (AUTO).
  • The maximum number of consecutive communication protocol checksum violations before the NP is considered unusable. A value of zero indicates no threshold exists.
  • Whether or not CPU time used for NP processing is being recorded.
The following information may be displayed if both the XP and the DETAIL operands are specified:
  • The algorithm used to select the CP or NP used to send a request to the database.
  • The maximum number of requests that may be sent to the database on a CP or NP without receiving a response, before the CP or NP is considered unresponsive.
