sql - How to interpret tkprof_table.ticks? -


i googled on web trying search meaning of tkprof_table.ticks not find anything.

can me understand ticks column means?

the following ticks show large value. not sum of other columns. far far close.

select parse_cnt,parse_elap,exe_count, exe_cpu, exe_elap,fetch_elap,ticks, sql_statement   tkprof_table  lower(sql_statement) '%set transaction isolation level%'  order ticks desc    parse_cnt parse_elap exe_count exe_cpu exe_elap fetch_elap      ticks sql_statement                                          10       1619        11   31250   164191          0 4294192015 set transaction isolation level serializable        10       1619        11   31250   164191          0 4294192015 set transaction isolation level serializable         1        102         1       0       59        696     355707 set transaction isolation level serializable         1        125         2       0    31984          0      87975 set transaction isolation level serializable         1        125         2       0    31984          0      87975 set transaction isolation level serializable

update ran 

tkprof main.trc tkprof.txt insert=tkprof.sql record=allsql.sql

the ticks column in tkprof_table generated in tkprof.sql

create table  tkprof_table (  date_of_insert                       date    ,cursor_num                           number  ,depth                                number  ,user_id                              number  ,parse_cnt                            number  ,parse_cpu                            number  ,parse_elap                           number  ,parse_disk                           number  ,parse_query                          number  ,parse_current                        number  ,parse_miss                           number  ,exe_count                            number  ,exe_cpu                              number  ,exe_elap                             number  ,exe_disk                             number  ,exe_query                            number  ,exe_current                          number  ,exe_miss                             number  ,exe_rows                             number  ,fetch_count                          number  ,fetch_cpu                            number  ,fetch_elap                           number  ,fetch_disk                           number  ,fetch_query                          number  ,fetch_current                        number  ,fetch_rows                           number  ,ticks                                number  ,sql_statement                        long  ); set sqlterminator off

i did define ticsk.

in general, should refer "clock ticks". specific meaning depend on how populated tkprof_table , how set tick attribute when collecting statistics. under common usage, can assume 1 tick equals 10 ms.
