[Info-vax] I guess VMS can't lose?

[jm]

Passenger reservation of Indian Railways runs on OVMS.  An n-tier,
distributed database environment.  This is not simple reservation
system.  It implements very complex policies framed by the Railway
Boards.  Sybase & Oracle tried earlier to migrate but failed.  Because
few things is extremely difficult to implement.  Performance is no way
near to the VMS and its layered products, especially the middleware,
Reliable Transaction Router (RTR).  Still uncrackable/unhackable
system.

Amsterdam Police Deptt. few years ago completed 10 years of uptime.
VMS is awarded world record of uptime of 19 years of uptime.

800 kms nodes of a cluster can be placed without compromise on
performance.  Best for disaster recovery.

The World Trade Center had strong-room where VMS servers were running,
and still running after that 9/11 disaster.  In intense heat, though
network was disconnected, air-conditioning
