Parsing in cursor:

len =the length of the cursor.
dep =recursive depth of cursor(0-parent,>0-child)
uid =user id
oct =oracle command type no OCI
lid =user id owning the statement e.g. package(libary user id)
tim =the time the parse began
hv =hash valus
ad =sql address of cursor
sqlid=sql id of cursor
END OF STMT=indicate the end of sql STateMenT


c =cpu time
e =elapsed time
p =number of database blocks read (physical)
cr =number of consistent mode blocks read(logical)
cu =number of current mode blocks read(logical)
mis=number of library cache misses
r =number of rows returned
dep=recursive depth of cursor
og =optimizer goal (1=all_rows, 2=first_rows, 3=rule and 4=choose)
plh=plan hash value
tim=


cr =BG(Backgroud) Consistent Read mode
pr =OS Buffer Gets
pw =OS Write Calls

nam =event name
ela =elapsed time

next three values after ela are indicate the P1, P2 and P3 variables for each specific event.

XCTEND =Transaction Commit END

rlbk True(1) if and only if the transaction was rolled back.
rd_only True(1) if and only if the transaction changed no data in the database
