Обсуждение: Multiuser testing -- PostgreSQL 7.3.4
Hello All,
How to test the "Multiuser testing" in PostgreSQL?. I used the apache bench "ab" tool for this one.
The following command execute the "test.php" 50 times concurrently.
$ ab -c 1 -n 50 http://127.0.0.1/test.php
The test.php file contains the following contents:
<?php
$dbconn = pg_connect("port=5432 dbname=test user=postgres");
$result = pg_exec ($dbconn, "update table1 set C2=C2+C1;");
$result = pg_exec ($dbconn, "update table1 set C2=C2-C1;");
pg_close($dbconn);
?>
$dbconn = pg_connect("port=5432 dbname=test user=postgres");
$result = pg_exec ($dbconn, "update table1 set C2=C2+C1;");
$result = pg_exec ($dbconn, "update table1 set C2=C2-C1;");
pg_close($dbconn);
?>
Is this the correct way for MULTIUSER testing?
Is any other way available for MULTIUSER testing in PostgreSQL?
Help greately appreciated.
Regs,
Durai.

For a real world test you would need several scripts doing different things: updates to different rows, insertions, maybe deletes. Set them up to be reachable from your web server somehow, and then pass the URLs to siege (http://joedog.org/siege/). -- Alvaro Herrera (<alvherre[@]dcc.uchile.cl>) "The West won the world not by the superiority of its ideas or values or religion but rather by its superiority in applying organized violence.
