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.

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 ().

Regards;

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,Masataka

Successfully added gtm proxy but having issue with coordinator and datanode.

Coordinator :
Syntax : add coordinator master name host port pooler dir
here what value i should use in place of pooler ? pooler port ?

Yes, pooler port.


Command : pgxc_ctl add coordinator master coord3 node5 20004 20010  /home/postgres/pgxc/nodes/coord
ERROR: sorry found some inconflicts in coordinator master configuration.

Please check if you assigned duplicate resource to coord3?    You should not assign the same port number or work directory which has already been assigned to other nodes.


pgxc_ctl add coordinator master coord3 node5 20004 /home/postgres/pgxc/nodes/coord
ERROR: please specify the working director for the coordinator master

Datanode :
Syntax : add datanode master name host port dir
Command : pgxc_ctl add datanode master new node5 20008 /home/postgres/pgxc/nodes/dn_master
 ERROR: sorry found some inconflicts in datanode master configuration.

The same as above.

Sorry, I was on my way back to Japan and took long to respond.

Does earlier manual installation could be reason for this issue ?

P.S:
gtm_prxy : Nodename: 'gtm_pxy3', port: 20001, dir: '/home/postgres/pgxc/nodes/gtm_pxy'
Coordinator Master: Nodename: 'coord3', port: 20004, pooler port: 20010, dir:' /home/postgres/pgxc/nodes/coord'
Datanode Master :   Nodename: 'datanode3', port: 20008, dir:' /home/postgres/pgxc/nodes/dn_master'

please look at my commands if its erroneous

Please advice.

As Mason mentioned, yes automatic selection of a coordinator will help
for load balancing as well.

JDBC has some capability which selects one of the connection point
from url list but libpq does not.

Libpq/JDBC extension for load balancing (and to search for live
coordinator) will be a nice extension.

Hi Koichi,Masataka

Successfully added gtm proxy but having issue with coordinator and datanode.

Coordinator :
Syntax : add coordinator master name host port pooler dir
here what value i should use in place of pooler ? pooler port ?

Yes, pooler port.


Command : pgxc_ctl add coordinator master coord3 node5 20004 20010  /home/postgres/pgxc/nodes/coord
ERROR: sorry found some inconflicts in coordinator master configuration.

Please check if you assigned duplicate resource to coord3?    You should not assign the same port number or work directory which has already been assigned to other nodes.


pgxc_ctl add coordinator master coord3 node5 20004 /home/postgres/pgxc/nodes/coord
ERROR: please specify the working director for the coordinator master

Datanode :
Syntax : add datanode master name host port dir
Command : pgxc_ctl add datanode master new node5 20008 /home/postgres/pgxc/nodes/dn_master
 ERROR: sorry found some inconflicts in datanode master configuration.

The same as above.

Sorry, I was on my way back to Japan and took long to respond.

Koichi Suzuki


Does earlier manual installation could be reason for this issue ?

P.S:
gtm_prxy : Nodename: 'gtm_pxy3', port: 20001, dir: '/home/postgres/pgxc/nodes/gtm_pxy'
Coordinator Master: Nodename: 'coord3', port: 20004, pooler port: 20010, dir:' /home/postgres/pgxc/nodes/coord'
Datanode Master :   Nodename: 'datanode3', port: 20008, dir:' /home/postgres/pgxc/nodes/dn_master'

please look at my commands if its erroneous

Please advice.

Sorry guys.  Yes, I've clearly confused isolation levels and this is
indeed fine.  The other session did commit its data by the time the
first session went to query the table again, so there's nothing wrong
with it.

Apologies for the noise.

Although my question about savepoints still stands.  Will those be
supported in future?

Thanks

Thom

You did not say whether this "another transaction" is still open or already
committed. If that "another transaction" is committed, then I don't see any
problem with the results. The transaction running select query is in
read-committed mode and hence it can see the results of the other
transaction.

Thanks,

Hello Thom,

As far as I know, Postgres-XC supports the read committed isolation
level and it is the default level.
I think it is a critical problem that uncommitted data is visible in
other READ COMMITTED transaction.

I tested your report on 1.2 beta in my hand with 2 coordinators and 2
datanodes, but it is not reproduced.

Can you provide your PGXC version (or commit ID), deployment,
configuration and whole the script?

Hi,

I've just started trying to familiarise myself with Postgres-XC, but
I'm a bit concerned about dirty reads that occur:

postgres=# begin;
BEGIN
postgres=# insert into moo (thing) values ('alpha');
INSERT 0 1

--another transaction inserts (6,beta)

postgres=# select * from moo;
 id | thing
----+-------
  1 | hello
  2 | howdy
  5 | alpha
  6 | beta
  3 | bark
  4 | hiss
(6 rows)

-- we're seeing (6,beta) but shouldn't have visibility of it,
effectively a dirty read.

-- another transaction inserts (7,gamma)

postgres=# select * from moo;
 id | thing
----+-------
  1 | hello
  2 | howdy
  5 | alpha
  6 | beta
  3 | bark
  4 | hiss
  7 | gamma
(7 rows)

-- (7, gamma) shouldn't be visible, another dirty read

postgres=# delete from moo where thing = 'beta';
DELETE 1
-- we successfully deleted a row we shouldn't have been able to see.

postgres=# rollback;
ROLLBACK
postgres=# select * from moo;
 id | thing
----+-------
  1 | hello
  2 | howdy
  6 | beta
  3 | bark
  4 | hiss
  7 | gamma
(6 rows)

-- the (1, alpha) insert and (6,beta) delete were both rolled back.

Is this supposed to be one of the trade-offs with write-scaling?

I also noticed that savepoints aren't supported.  Will those be added?

Thanks

Thom

That could possibly be an interesting extension to GTM... but then if GTM
goes down you application would still not know where to look for the
standby.

You could also try the approach outlined in a blog posting here,
essentially using DNS to load balance amongst multiple coordinators.

Hi koichi,zhangzl

Thanks for your suggestions.

So i have to connect my application to directly one of coordinator right.
I thought i have to connect my application to GTM from where my application
will use one of available coordinator.

In this case if i connect my application to connect specific coordinator
using port
then what will happen if that coordinator goes down ?

in the case of GTM when i execute simply Psql -dkoichi then it selects
available
coordinator automatically, this is not possible to setup with application?
if i am able to
connect my application to directly GTM and then it will select any of
available coordinator.

Please suggest.

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.

Use h instead of H；

Maybe you should check your pg_hba.conf file if you still cannot connect to
it.

主题: [Postgres-xc-general] Where to connect to communicate pgxc with
Application

 

Hi all,

I have just setup postgre-xc with four servers for testing.

with this four system from GTM server i am able to connect

to database and it selects one of coordinator,. it just works fine.

But now i want to integrate this with my application where application

is on separate server. 

so in this case where to connect in pgxc ?

which IP and port i should set in my application to communicate with it?

>From some documentation i came to know i should connect to coordinator

but from other system i am not able connect to the database. i am getting
this

 

[postgres@localhost ~]$ psql -H 192.168.1.73 -U postgres -d dbname -p 20004
psql: warning: extra command-line argument "192.168.1.73" ignored
psql: could not connect to server: No such file or directory
        Is the server running locally and accepting
        connections on Unix domain socket "/tmp/.s.PGSQL.20004"?

 

 

But on this server seems socket port is open

[root@localhost ~]# netstat -pan | grep postgre

You need to specify coordinator's host and port with -h and -p option
respectively.   Otherwise, psql will assume local host and 5432 for
these parameter, which you have not configured.

When you create tables (this is mostly done in the above case),
Postgres-XC assumes each table is distributed by the first column.
You can correct this afterwords with ALTER TABLE.   If you'd like to
distribute/replicate tables, you should run CREATE TABLE in advance.
Then data will be distributed as you wish from the scratch.

Application can connect to ANY coordinator (not datanode).   So most
likely is to assign different coordinator to different application
instance.   You can use usual -p and -h parameter for different
coordinator from your applications.

All the coordinator provides the same database view and any updating
transaction is propagated to all the node without conflict.

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 ().

Hi all,

I have just setup postgre-xc with four servers for testing.
with this four system from GTM server i am able to connect
to database and it selects one of coordinator,. it just works fine.

But now i want to integrate this with my application where application
is on separate server.

so in this case where to connect in pgxc ?

which IP and port i should set in my application to communicate with it?

>From some documentation i came to know i should connect to coordinator
but from other system i am not able connect to the database. i am getting
this

[postgres@localhost ~]$ psql -H 192.168.1.73 -U postgres -d dbname -p 20004

>         Is the server running locally and accepting

But on this server seems socket port is open

Hi All,

I have just setup postgre-xc with four servers for testing.
but i have some questions regarding import process.

I just found this link to backup and dump
http://postgres-xc.sourceforge.net/docs/1_0/backup-dump.html

my question is do i need to specifu coordinator name or datanode name
or port for restoring dump file?

If i don't specify datanode and port then where this data will be imported ?

PGXC psql -d astpp /home/postgres/itn-gtm.sql
psql: could not connect to server: No such file or directory
        Is the server running locally and accepting
        connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

PGXC psql astpp < /home/postgres/itn-gtm.sql
psql: could not connect to server: No such file or directory
        Is the server running locally and accepting
        connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

I have dump of postgresql database which i want to import in postgre-xc
but its gving me above error

So here what i need to do make it working ?

Hi Masataka, Koichi,

New datanode is successfully added and all components are running.i have
small doubt.

As i just added new datanode so , will existing database automatically
copied
on this datanode or i have to create and import it manually from another
datanode ?

As per that video, we need to just fire alter query just like :
*alter table t1 add node (datanode3);*
is that so ?

and yeah as of now i am getting Failed to get pooled connections error.
koichi=# execute direct on (datanode3) 'select * from t1';
ERROR:  Failed to get pooled connections

Please advice.
