The Top Activity Section is composed of a series of tabs that provide detailed statistics on individual SQL statements and sessions that were waiting or executing over the length of a profiling session.
- The top SQL tab provides more detailed information than provided on the Overview tab, in terms of executing SQL statements and procedures. For more information, see Top SQL tab.
- The top Events tab displays information about wait events profiled by the execution process. For more information, see Top Events tab.
- The top Sessions tab displays information about sessions profiled by the execution process. For more information, see Top Sessions tab.
- The top Blockers tab displays information about blocking sessions. For more information, see Top Blockers tab.
- The top ObjectI/O tab (Oracle-Specific) tab does not appear in the Top Activity Section unless the data source being profiled is an Oracle platform. This tab tab displays information about the I/O profiled by the execution process. For more information, see Top Object I/O tab.
