The Private Key File
Private Key File Contention
Private Key File Contention
In cases where a user is running multiple CDSA applications, it is possible that private
key file contention will occur. The HP-UX CSPs employ an interlock mechanism to insure
that the private key file will be accessed in an atomic action. Application developers
should be aware that the efficiency of the interlock algorithms may be inadequate to
support very high speed server applications. In these cases it will be necessary for the
application developer to engineer their own private key handling facility that is optimized
for their particular application domain.
