I'm creating a query on the composite_instance table in the soainfra schema (11g). Now I wanted to make a translation of the STATE column.
I found that the different possible states from the composite instance table are:
RUNNING = 0
RECOVERY REQUIRED = 1
COMPLETED SUCCESSFULLY = 2
FAULTED = 3
TERMINATED BY USER = 4
SUSPENDED = 5
STALE = 6
UNKNOWN= 32

However I found records in the table with states 34,64 and 66.
What do these states mean? Is this faulted data or simply undocumented states?
