It’s a nice try. Besides that, many enhancements are possible, like merging multiple tracefiles without trcsess or cat invokation.

– get exact file_name
select replace(value,(select value||’\’ from v$diag_info where name=’Diag Trace’),”) into v_filename
from v$diag_info where name=’Default Trace File’;

cheers

Yes, external table is another solution, but pipelined table function version is more flexible and easy to manage.

Anyway, I really like your regular expression solution! :)

You could also use External Tables like this:

SQL> drop table trace_table ;

Table dropped.

SQL>
SQL> create table
2 trace_table ( txt varchar2(1000) )
3 organization external (
4 type oracle_loader
5 default directory TRACE_DIR
6 access parameters (
7 records delimited by newline
8 )
9 location(‘mydb_ora_3248_bbw2.trc’)
10 );

Table created.

SQL>
SQL> Column Cur_Id Format a6
SQL> Column Event Format a30
SQL> Column Class Format a5
SQL>
SQL> Select Cursor_number Cur_Id,
2 Event,
3 Class,

13 Cursor_number,

15 Class
16 Order by Cursor_number;
