NO_REMOTE, remote NICE process not available Facility: NIC Explanation: Attempt at loopback failed. User Action: Ensure that the NICE object can run at remote node.
NORESOURCE, resource error Facility: NIC Explanation: A resource error, such as a system service failure, occurred during an attempt to complete the specified command. User Action: Repeat the command. If the error persists, ensure that the system pool is adequate and that the configuration data base is consistent.
NO_ROOM, no room for new entry Facility: NIC Explanation: No room for new entry in database. User Action: Delete unwanted items from database.
PRGERR, NICE process program error Facility: NIC Explanation: A software error occurred, User Action: Collect as much information as possible and submit an SPR.
DLE Messages
LOADFAIL, DECnet line 'line': downline load failure Facility: DLE Explanation: Down-line load failed. User Action: Refer to the accompanying message.
STARTING, DECnet line 'line-number' starting downline load Facility: DLE Explanation: A boot request was initiated by the satellite system. User Action: None.
Miscellaneous Messages
ABORT, abort Facility: VAX/VMS System Services Explanation: An attempted operation was aborted: 1. The system returns this status for an I/O request that was canceled before it was completed. 2. Following a network request, this status indicates that a logical link was disconnected. User Action: The operating system does not normally display this message; user programs should be coded to detect and respond to the status return.
ACCQUOTA, ACCOUNT had inadequate quota at remote node Facility: VAX/VMS System Services Explanation: This severe error message is associated with a Status code returned from a system service request. An attempt was made to initiate a DECnet logical link connection. The target object is already using its quota of logical links or some other resource. User Action: This condition is not usually permanent. Try to initiate the connection later. Consult the DECnet-VAX User's Guide for additional information.
BADPARAM, bad parameter value Facility: VAX/VMS System Services Explanation: A value specified for a system function is not valid. Several conditions can cause this error: 1. If this message occurs as a result of a call to a file system ACP function, it indicates that parameter listoptions are not valid. 2. If this message occurs as a result of a call to the Formatted ASCII Output (SFAO) system service, it indicates that a control string contained an unknown directive. 3. If this message occurs as a result of a call to a network ACP control function, it indicates that one of the function parameters is out of range or has a bad format. 4. If this message is associated with a status code returned by a request to a DR32 interface, an attempt was made to set the data rate higher than the rate allowed by the SYSGEN parameter /XFMAXRATE. 5. If this message is associated with a status code returned by a request to a DR11-W interface, an odd transfer count was specified. User Action: Determine the system service call that returned the error, using the debugger if necessary. Verify that the call to the service was coded correctly. See the VAX/VMS System Services Reference Manual for coding specifications.
BUG_DAP, internal network error condition detected; DAP code=xxxxxx Facility: VAX-11 RMS Explanation: A Data Access Protocol violation was detected by VAX-11 RMS while attempting to communicate with the Remote Access Listener. User Action: Collect as much information as possible and submit an SPR. The status value (STV) field of the FAB or RAB contains the DAP status code. Consult the DECnet-VAX User's Guide to interpret the status code. Note, however, that the explanation is intended for users who are familiar with DAP.
CRC, network DAP level CRC check failed Facility: VAX-11 RMS Explanation: CRC checksums computed by VAX-11 RMS and the File Access Listener (FAL) program did not match when compared during an RMS close operation. User Action: The file that was created or modified may be corrupted. Repeat the file access. If the CRC error on close persists, the communication hardware is malfunctioning.
DIRFULL, directory is full Facility: VAX/VMS System Services Explanation: This message is associated with a status code returned from a file system ACP QIO request. The message indicates that an error occurred while a disk file was being created because the directory specified is full and cannot catalog any more entries. The maximum size of a directory file is 1024 blocks. If associated with a DECnet operation, this message indicates that the directory of declared network names is full. User Action: Delete or purge unwanted files from the directory and repeat the request; specify a different directory for the output file; or, organize the directory into subdirectory levels to obtain more cataloging space.
FILALRACC, file already accessed on channel Facility: VAX/VMS System Services Explanation: This message is associated with a DECnet operation. A logical link already exists or is pending. User Action: Check for a programming error.
