Library /sys$common/syshlp/nclhelp.hlb flush (OpenVMS)  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Removes one or more entries from the in-memory, local
    naming cache.

    flush [node node-id] session control naming cache entry "node-name"

    Note: The NCL session control naming cache (CDI cache)
    is not related to the DECdns cache files.

    To flush entire cache (with the exception of those for the local
    node and any aliases it may be using):

      flush session control naming cache entry "*"

    Or to flush single entries:

      flush session control naming cache entry "lamchp"

      flush session control naming cache entry "NET$490014000400010020"
