show [node node-id] session control - backtranslation softlink softlinkname attribute [,attribute...] all [attributes] all counters all identifiers all status Shows the backtranslation softlink subentities in the session control database on the specified node. If the node is using the DECdns directory service, then such one softlink subentity should exist for each DECnet address held by the node. (Softlinks are NOT created for cluster alias addresses.) If an OpenVMS node is configured to run DECnet over IP and is using the DECdns namespace, then one softlink subentity should exist for each non-zero IP address as well. Softlinks in the DECdns namespace are used by all nodes in the namespace to associate a particular address with a nodename (DNS$LinkTarget). Therefore, if a node's backtranslation softlinks are not properly configured within a DECdns namespace, then other nodes using that namespace will not be able to associate that address with correct nodename. NCL can be used to show what softlinks the node can be configured to maintain in the specified DECdns namespace. If the session control attribute maintain backward softlinks is true, then the node will periodically attempt to update its softlinks in the DECdns namespace. If the NCL SHOW command indicates a high Update Failure rate, the Last Failure Reason may suggest the reason for the failure. You may then use the DNS$CONTROL and DECNET_REGISTER tools to troubleshoot. These tools can be used to confirm that a DECdns server is accessible and that the DECdns namespace contains the proper object and softlinks for this node. Examples: show node WINTER:.XPR.CASE session control backtrans softlink * all ! Shows all softlinks contained in the session control ! database of node WINTER:.XPR.CASE. show session control backtranslation softlink - WINTER:.DNA_BACKTRANSLATION.%X49.%X0018.%XAA0004002A60 all ! Shows a softlink contained in the session control database ! for the local node. It indicates that the node is the ! holder of DECnet address 24.42 within the WINTER namespace. show session control backtranslation softlink - WINTER:.DNA_BACKTRANSLATION.%XA1725E45 all ! This softlink indicates that the local node is configured ! as the holder of the IP address 161.114.94.69 in the ! WINTER namespace. (IP softlinks are on OpenVMS only)
1 – Identifier
o name Simplename assigned when it was created.
2 – status
o uid Entity's unique identifier, generated when it was created. o target Target (or nodename) associated with this softlink. o network entity title Network entity title for this softlink. Since the concept of a NET makes no sense for IP softlinks, the hexadecimal representation of the IP address is displayed instead. o state Status of this entity instance. Values include create, delete, exist and retarget. o last successful update Most recent time an update for this subentity succeeded. o last update completed Most recent time an update for this subentity completed. o last update started Most recent time an update for this subentity was initiated. o last failure reason Reason for the most recent update failure.
3 – Counters
o creation time Time when the subentity was created. o update failures Number of times an update for this subentity failed. o update successes Number of times an update for this subentity succeeded.
