This then adds value to tracing at level 4 (provided the cursor is still cached ), since tracing at levels higher than 4 will already include the execution plan in the trace file. I think I will still prefer to use level 8, or 12 when tracing. I like that all the information for analysis is tyhen captured in the one file. Regards, M. Hi Chris,

There is this enhancement as well. The field "plh" is the hash value of the execution plan. In other words, it matches the column plan_hash_value in v$sql_plan (and similar views...). This is an interesting information when a given SQL statement has several child cursors. Best regards, Chris Hi Mathew

I wonder if this is a handle to reference the source of the SQL? ie: Ease the identification of SQL sourced in the same stored procedure/package?
