7.5.5. Errors
DCBM errors caught are reported in the
errors
section of the
/status
API. This section is
composed of a list of flags.
Any error has the following impact:
• Block new transactions
• Display the error(s) on screen
Any error remains until a power down. All errors
are cleared on a reboot, then raised again if
errors still exist. The DCBM checks the presence
of all errors within the first 10 seconds, most of
them are re-checked cyclically.
0 is the error value corresponding to the nominal state of the DCBM. Any other value prevents new
transactions.
i
An on-going transaction is not interrupted by an error. But the error
invalidates the transaction through the
transactionStatus
.
All errors display the screen shown on adjacent figure (the
FF#
value refers to
value
field)
