Data generated by locking event monitors
Locking event monitors produce data
about locks and deadlocks in the system. You can choose to have the
output from a locking event monitor to regular tables, or to an unformatted
event (UE) table.
If data is written to
a UE table, you must perform post-processing on it to view the data.
Regardless of the output format you choose, locking event data
comes from one of four logical groups:
If you choose to have the locking event data written to regular
tables, data from an additional group (CONTROL) is used to generate
meta-data about the event monitor itself.
Note: By default, only deadlock
information is generated for locking event monitors. To have other
types of locking data generated, you must enable collection of that
data explicitly.
