I have been trying to configure PgPool to accept a requests of about 150. Postgres server is configured to accept only 100 connections. Anything beyond 100 need to be pooled by PgPool. I don't seem to get that. I only require PgPool to queue the requests, my current configuration does not do that. From my JMeter test, when I try to get connection beyond 100, postgres gives me an error saying PSQL error: sorry, too many clients.

I only have configured PGPool with the following parameters :

listen_address = 'localhost'
port = 9999
backend_hostname0 = 'localhost'
backend_port0 = 5432
num_init_children = 100
max_pool = 4
child_life_time =120
child_max_connections = 0
connections_life_tome = 120
client_idle_limit = 0

Since I only require PgPool to Queue the extra connections requests, is the above configuration correct? Please advise on the proper configuration.

I am a newbie in JMeter, How do i test the sending of byte stream as request to a Servlet. where this Servlet is receiving it as a stream(DataInputStream), then saving it as a appropriate file. the situation is, we are sending a file as stream to a servlet from a mobile application. we have to test the performance of the servlet.

i have tried to HttpRequest but didnt work, how do i test to send the streams?

There is no solution for this?? or how should i do it otherwise.. Please advice folks..
This is reining my new year..

Please suggest me folks..

But what is your configuration so far.

my apologies for not posting in appropriate forum, Since i my code is servlet based i posted in servlet subform.

here is the configuration file i am testing.
i get a warning saying rollingpolicy must be declared and the old log does not get zipped .
i have searched through google and have not found any solution yet. although i did find an example mentioning that it should declared in the POM.xml file for Maven projects,
my project does not contain this POM.xml file. how do i solve this?? Please help

Hey folks,

i have a need of archiving the log in zip or gz format.
when i run the application, i get an lo4j :WARN Element type "rollingpolicy" must be declared
and it does not create a zipped file.
i have created a log4j configuration file in a xml format.
Where do i have to declare this ??

hey folks..

This is weird but, i get this error while trying to insert or access the table through hibernate. Thing is.. i was able to insert properly in the beginning when i developed it. after a while i get this kind of error where i cant insert nor can i access the table rows. I have observed that sometimes it mapps and sometimes it doesnt(random way). Is there some property i need to set? or something like that?

PS: when i clean my project in Myeclipse it works sometimes and sometimes it doesnt. I didnt make any syntactical error .. i was able to run it . i can access at random times.
