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 > 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 > tcp 0 0 0.0.0.0:20004 0.0.0.0:* > LISTEN 9454/postgres > tcp 0 0 0.0.0.0:20008 0.0.0.0:* > LISTEN 9522/postgres > tcp 0 0 192.168.1.73:20008 192.168.1.73:33950 > ESTABLISHED 10025/postgres > tcp 0 0 192.168.1.73:33950 192.168.1.73:20008 > ESTABLISHED 9459/postgres > tcp 0 0 192.168.1.73:35014 192.168.1.73:20001 > ESTABLISHED 9522/postgres > tcp 0 0 192.168.1.73:35006 192.168.1.73:20001 > ESTABLISHED 9454/postgres > tcp 0 0 192.168.1.73:57794 192.168.1.43:20009 > ESTABLISHED 9459/postgres > tcp 0 0 :::20004 > :::* LISTEN 9454/postgres > tcp 0 0 :::20008 > :::* LISTEN 9522/postgres > udp 0 0 ::1:60142 > ::1:60142 ESTABLISHED 9522/postgres > udp 0 0 ::1:59683 > ::1:59683 ESTABLISHED 9454/postgres > unix 2 [ ACC ] STREAM LISTENING 84606 > 9454/postgres /tmp/.s.PGSQL.20004 > unix 2 [ ACC ] STREAM LISTENING 84641 > 9459/postgres /tmp/.s.PGPOOL.20010 > unix 2 [ ACC ] STREAM LISTENING 85268 > 9522/postgres /tmp/.s.PGSQL.20008 > am i doing correct ?

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 ? -- Thanks, Juned Khan iNextrix Technologies Pvt Ltd. www.inextrix.com |

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.

Hi Masataka, Its fine but i think i have specified only one element for each parameter. please check my command if it needs any correction *pgxc_ctl add coordinator master coord3 node5 20004 20010 /home/postgres/pgxc/nodes/coord* On Thu, Mar 13, 2014 at 7:07 PM, Masataka Saito <pg...@gm...> wrote: > Sorry.

Sorry. I lead your misunderstanding. I meant about array style parameters and number of elements in each array. For example, you have one coordNames, almost of array style parameters for coordinators except for coordPgHbaEntries -- coordPorts, poolerPorts, coordMasterServers, coordMasterDirs, coordMaxWALSenders, coordSpecificExtraConfig, coordSpecificExtraPgHba -- must have only one element. That's all I can guess by your description. Regards.

Hi Masataka, As per that documentation i have provided all those parameters what else i should add or remove to make that command working ? I want to add datanode and coordinator with below configuration and i think i specified all values as per that documentation.

I tried to add coordinator and datanode manually and now it seems everything is messed up. Every component is just stopped working, if i kill all and start all again then again its shows everything is running but in that case it takes too long to connect dtabase(Psql -dkoichi) and at last it just fails to connect to the database *PGXC Psql -dkoichiSelected coord1.psql: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request.PGXC * Please advice.

Hi Koichi, Masataka, With ALTER query it throws postgres=# ALTER NODE coord3 WITH (PORT = 20004, HOST = 'node5'); ERROR: Failed to get pooled connections CONTEXT: SQL statement "EXECUTE DIRECT ON (coord1) 'SELECT pg_catalog.pg_try_advisory_xact_lock_shared(65535, 0)'" Please advice.
