can also enter this command through the NCL interface. You can
use any combination of attribute specifiers in any sequence in
a single command. Use a comma to separate specifiers. If you
do not supply any attribute specifier, the command displays all
identifiers and their values.
PRIVILEGES REQUIRED
You must have the NET$EXAMINE rights identifier on a VMS system. No
special privileges are required on an ULTRIX system.
4.2.1 – attributes
The following are descriptions of valid characteristics, counters, and status attributes: CHARACTERISTICS Future Skew Specifies the maximum amount of time that a timestamp can vary from local system time at the server node. This characteristic ensures data consistency. Maximum Protocol Version Specifies the maximum version of the DECdns clerk/server protocol that this particular DECdns server supports. Minimum Protocol Version Specifies the minimum version of the DECdns clerk/server protocol that this particular DECdns server supports. UID Uniquely identifies the entity. Version Specifies the version of the architecture implemented by this server. COUNTERS Authentication Failures Specifies the number of times a requesting principal failed authentication procedures. Child Pointer Update Failures Specifies the number of times the server background process was unable to contact all the clearinghouses where a replica of a particular child directory's parent directory is stored, and was therefore unable to apply the child updates that have occurred since the last skulk. This counter increases by one at each occurrence of the Cannot Update Child Pointer event. Creation Time Specifies the time when the DECdns server entity was created. Crucial Replica Removals Backed Out Specifies the number of times a user attempted (from this server) to remove a replica that is crucial to the connectivity of a directory hierarchy. The server background process prevents users from accidentally disconnecting lower-level directories from higher- level directories. When it detects an attempt to remove a crucial replica, it will not execute the command to do so. This counter increases by one at each occurrence of the Crucial Replica event. Incompatible Protocol Errors Accounts for the total number of requests received by this server from a clerk running an incompatible protocol version. A server can communicate with any clerk running the same protocol version, or the version previous to the one it is running. This counter increases by one at each occurrence of the Incompatible Request event. Possible Cycles Specifies the number of times this server followed a chain and encountered an entry already in the chain. For example, a soft link is created that points to a series of links that eventually point back to the first link, or a group which is a member of itself. This counter increases by one at occurrence of the Possible Cycles event. Read Accesses Specifies the number of read operations directed to this DECdns server. Security Failures Specifies the number of times the Security Failures event was generated. This counter is increased whenever a DECdns server has insufficient access rights to a directory or object to perform either a client-requested action or a background operation. Skulks Completed Specifies the number of skulks that were successfully completed by this DECdns server. Skulks Initiated Specifies the number of skulks that were initiated by this DECdns server. Times Lookup Paths Broken Specifies the number of broken connections between clearinghouses on this server and clearinghouses closer to the root. Incoming requests to this server that require a downward lookup in the directory hierarchy may still succeed, but requests requiring lookup in directories closer to the root will fail. This counter increases by one at each occurrence of the Broken Lookup Paths event. Write Accesses Specifies the number of write operations to this DECdns server. STATUS ATTRIBUTES State Specifies the state of the DECdns server. Broken The server has a fatal error condition. Initial The server is initializing. Off The server is not available. On The server is running and available. Shut The server is undergoing an orderly shutdown.
4.2.2 – example
