[Pgpool-general] [pgpool problem] about streaming replication and load balancing.

[イジュヨン]

hello, developers and anybody using pgpool.

i have a something problem about 'streaming replication' and 'load balancing'.
i don't know what mail address for to ask like this problem. then i
send this asking mail to you.
(if i mistake this doing, please teach me that i can ask mailling list.)

well, my question is this)

<server spac>
 - my 1st postgresql server(os:ubuntu10.4, ip:192.168.3.160,
postgresql version 9.1) run normal operations.
   (i checked that requested query success by use log)

 - my 2nd postgresql server(os:ubuntu10.4, ip:192.168.3.141,
postgresql version 9.1) run normal operations too.
   (i checked it too.)

 - my pgpool server(ip:192.168.3.160 - with 1st postgresql server,
pgpool version 3.1 -
http://ftp2.jp.postgresql.org/pub/postgresql/projects/pgFoundry/pgpool/pgpool-II-3.1.tar.gz)
run normal operations too.
   (i checked that requested query success by use log too.)

<i tried it>
i send query request to pgpool, and 1st postgresql catch it always.
it is a wrong working
 why i did set pgpools to 1:1000 about backend_weight0 and
backend_weight1 values.(look my pgpool.conf file)
i think that this case's good working is almost catch 2nd postgresql server.
i don't know this working reason(about wrong pgpool's load balancing
and after backend_hostname1 setting values).

do you have to teach me about this problem or something idea?
I hope your help. please help me.

i waiting your mail.
thanks.
