SESSION_ID- Same as the SID or Session ID and can be used to join to SID in other views/tables. SESSION_STATE- What was the state of the session when ASH recorded the sample. ON CPU/WAITING- The two session states in Active Session History. ON CPU is active, vs. Waiting, which is self-explanatory. EVENT- Type of event that the session is currently active or waiting on. TIME_WAITED- How long the session has been waiting if waiting. WAIT_TIME- Confusing- but this is populated by any wait time if the session is currently active for the previous waits. SQL_ID- The unique identifier for the SQL statement being executed. SQL_CHILD_NUMBER-The cursor child number.

Understand what is valuable and compare to packaged reports. Be aware on RAC of node specific data. Take care when querying Obj#, File# and Block#, (still issues in different versions…) Check the time that is available in buffer, don‟t assume!
