HP OpenVMS Systems

Memory Error Handling? (ECC)

» close window

The Question is:

 
How does an Alpha server running Open VMS handle a two (or more) bit ECC memory
 error.
 
Is the program using that memory exited or is
the system "machine checked" and rebooted, along with the usual crash dump ?

Alf Kellner.
 

The Answer is :

 
  The memory error implementation details are specific to particular
  AlphaServer systems, with different models potentially implementing
  different error detection and error correction schemes.
 
  Uncorrectable errors generally result in either process or system
  errors, depending on what was residing within the failing memory.
 
  Soft errors are generally handled transparently, while hard errors
  will result in the addition of the memory onto the bad page list.
