Hi koichi,

I have already tried to reload but still its giving me same error.

postgres=# SELECT pgxc_pool_reload();
 pgxc_pool_reload
------------------
 t
(1 row)

koichi=# alter table t1 add node (datanode3);
ERROR:  Failed to get pooled connections


Although i am able to connect directly on datanode3.

Please suggest.

Sorry, made a silly reply.

Please try SELECT pgxc_pool_reload().   Documentation will be found at

What kind of error are you having?

Koichi Suzuki

2014/03/19 20:56、Juned Khan <jkh...@gm...<mailto:jkh...@gm...>> のメール：

Hi koichi,

Having little bit issue.
New datanode is added successfully and even database structure is copied
on new datanode(i have added datanode3).

But as tables are empty, i am just trying to add new datanode using below command

koichi=# alter table t1 add node (datanode3);
ERROR:  Failed to get pooled connections

But as you suggested i tried to clean the connection.

postgres=# CLEAN CONNECTION TO COORDINATOR (coord1,coord2) FOR koichi;
CLEAN CONNECTION

postgres=# CLEAN CONNECTION TO NODE (datanode1,datanode2,datanode3) for database koichi;
CLEAN CONNECTION

But still its giving me same error, is there any other solution for this problem?

Regards,
Juned khan

Hi Koichi,

Thanks for your information,
i just tried with stop and start components and it worked.

This link will help me to fix future issues. And i ll keep in mind
about that documentation bug.

pgxc_ctl command "add datanode master" should run all the necessary
clean_connection calls.

Try to run clean_connection SQL command (specific to XC) as seen in
http://postgres-xc.sourceforge.net/docs/1_1/sql-cleanconnection.html

I found a document bug in the example CLEAN CONNECTION TO COORDINATOR
coord1,coord2 FOR DATABASEname;

You should enclose set of node names with ().
