All of these are commonly refered to as SQL Injection Faults
Fault Injection – Reader or Writer Crash
ALTER SYSTEM CRASH [ INSTANCE I DISPATCHER | NODE ]; Instance = DB instance (default crash type) Dispatcher = writes updates to the cluster volume Node = Instance + Dispatcher
Fault Injection – Replica Failure
ALTER SYSTEM SIMULATE
percentage_of_failure PERCENT READ REPLICA FAILURE [ TO ALL I TO "replica name" ]
FOR INTERVAL quantity
{ YEAR I QUARTER | MONTH | WEEK | DAY | HOUR MINUTE I SECOND };
percentage_of_failure - % of requests to block
TO ALL / TO = simulate failure of all or a specific replica
Fault Injection Disk Failure
ALTER SYSTEM SIMULATE
percentage_of_failure PERCENT DISK FAILURE [ IN DISK index | NODE index ]
FOR INTERVAL quantity
{ YEAR I QUARTER | MONTH | WEEK | DAY | HOUR MINUTE I SECOND };
percentage_of_failure = % of the disk to mark as faulting DISK index = simulate failure of a specific logical block of data NODE index = simulate failure of a specific storage node
