Top PL/SQL Procedures

'PL/SQL entry subprogram' represents the application's top-level entry-point(procedure, function, trigger, package initialization or RPC call) into PL/SQL.
'PL/SQL current subprogram' is the pl/sql subprogram being executed at the point of sampling . If the value is 'SQL', it represents the percentage of time spent executing SQL for the particular plsql entry subprogram

PLSQL Entry Subprogram	% Activity	PLSQL Current Subprogram	% Current

Top Sessions

No data exists for this section of the report.

Top Blocking Sessions

Blocking session activity percentages are calculated with respect to waits on enqueues, latches and "buffer busy" only
'% Activity' represents the load on the database caused by a particular blocking session
'# Samples Active' shows the number of ASH samples in which the blocking session was found active.
'XIDs' shows the number of distinct transaction IDs sampled in ASH when the blocking session was found active.

Activity Over Time

Analysis period is divided into smaller time slots
Top 3 events are reported in each of those slots
'Slot Count' shows the number of ASH samples in that slot
'Event Count' shows the number of ASH samples waiting for that event in that slot
'% Event' is 'Event Count' over all ASH samples in the analysis period
