>From the metalink...Even the reference guide, does not mention this
enqueue.. Document bug.
JI "Enqueue used during
AJV
snapshot refresh"
The JI lock was
introduced in
Oracle8.1
How Many Resources: One
per
snapshot
How Many Locks: One per
snapshot
When & How Used: Used
to
serialize snapshot
refresh for
a snapshot / mview.
TC seems to be an enqueue related with PQO.
