A VAX cluster computer configuration drives the two jukeboxes, as well as providing network connections to the NASA science community including NSI-DECnet, Internet and US SprintNet. One of the primary obligations is that the data must be kept safe and secure.
Data integrity is an important requirement as well.
Of equal importance is our obligation to disseminate data from the archive. In sections 3 and 4, we discuss some of the characteristics and lessons of the ingest and disseminate functions. The modular NSS software is written in C Language to provide us a measure of portability. The NSS direct applications interface is available through a command line interface and C Call routines. The 'store' transaction is performed in a sequential, 'batch' mode, first storing the pointer to the data on the mass storage system in the database and then actually storing the data on the mass storage device.
