informix odbc connection slow to open in asp.net -

-

i have application takes long time open odbc connections (like 20 sec) takes forever using arcmap , arcsde

but when try connection on odbc data source administrator, tests fast

does have idea of causing this?

btw application works fine in computer database

thanks.

in odbc administrator can enable tracing. compare trace file both slow , fast machine. if there "fast" open machine using odbc administrator , "slow" app try other ways open such connection. try use other tool such querytool (free trial), or create simple script in python win32 extension. in python (i recommend active python has win32 included) can open odbc with:

import odbc import time  t_start = time.time() conn = odbc.odbc('db_alias/user/passwd') t_stop = time.time() print('open: %.3f [ms]' % (t_stop-t_start)) cursor = conn.cursor()  cursor.execute("select first 1 dbinfo('version','full') systables;") row in cursor.fetchall():     print('[%s]' % (row[0]))

(note informix specific version select)

(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."
