sqlplus - Oracle - timed sampling from v$session_longops -

-

i trying track performance on procedures run slow (and seem keep getting slower). using v$session_longops track how work has been done, , have query (sofar/((v$session_longops.last_update_time-v$session_longops.start_time)*24*60*60)) tells me rate @ work being done.

what i'd able capture rate @ work being done , how changes on time. right now, re-execute query manually, , copy/paste excel. not optimal, when phone rings or else happens interrupt sampling frequency.

is there way have script in sql*plus run query evern n seconds, spool results file, , continue doing until job ends?

(oracle 10g)

tanel poder's snapper script wonderful job of actively monitoring performance. has parameters for

<seconds_in_snap> - number of seconds between taking snapshots <snapshot_count>  - number of snapshots take ( maximum value power(2,31)-1 )

it uses pl/sql , call dbms_lock.sleep

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
