tkprof: 格式化输出sql trace文件
[oracle@stressdb dbhome_1]$ tkprof
Usage: tkprof tracefile outputfile [explain= ] [table= ]
[print= ] [insert= ] [sys= ] [sort= ]
table=schema.tablename Use 'schema.tablename' with 'explain=' option.
explain=user/password Connect to ORACLE and issue EXPLAIN PLAN.
print=integer List only the first 'integer' SQL statements.
insert=filename List SQL statements and data inside INSERT statements.
sys=no TKPROF does not list SQL statements run as user SYS.
record=filename Record non-recursive statements found in the trace file.
waits=yes|no Record summary for any wait events found in the trace file.
sort=option Set of zero or more of the following sort options:
prscnt number of times parse was called
prscpu cpu time parsing
prsela elapsed time parsing
prsdsk number of disk reads during parse
prsqry number of buffers for consistent read during parse
prscu number of buffers for current read during parse
prsmis number of misses in library cache during parse
execnt number of execute was called
execpu cpu time spent executing
exeela elapsed time executing
exedsk number of disk reads during execute
exeqry number of buffers for consistent read during execute
execu number of buffers for current read during execute
exerow number of rows processed during execute
exemis number of library cache misses during execute
fchcnt number of times fetch was called
fchcpu cpu time spent fetching
fchela elapsed time fetching
fchdsk number of disk reads during fetch
fchqry number of buffers for consistent read during fetch
fchcu number of buffers for current read during fetch
fchrow number of rows fetched
userid userid of user that parsed the cursor
./test.txt explain=system/pwd aggregate=yes sys=no waits=yes sort=fchela
1. alter session set sql_trace=true; or exec dbms_monitor.session_trace_enable;
2. select sid,serial#,status from v$session where audsid=userenv('sessionid') and sid=(select sid from v$mystat where statistic#=1)
exec dbms_system.set_sql_trace_in_session(sid, serial#, true);
三、找到trace文件： show parameter user_dump_dest;
四、运行tkprof： tkprof /home/oracle/app/oracle/diag/rdbms/orcl/orcl/trace/orcl_ora_27186.trc ./test.txt explain=system/pwd aggregate=yes sys=no waits=yes sort=fchela
