Hi Masataka, For testing i am tried to get this work added manual query for CREATE NODE.

Hi Masataka Thanks for the information. I don't see explanation for pgxc_ctl (pgxc_ctl add or init) commands in below link, http://sourceforge.net/apps/mediawiki/postgres-xc/index.php?title=PGOpen2013_Postgres_Open_2013 Although i found a section "Add/Remove component dynamically" in that pdf but very less information is there. I tried to find available options using pgxc_ctl --help but no success. option: -c or --configuration conf_file: Specify configruration file. -v or --verbose: Specify verbose output. -V or --version: Print version and exit. -l or --logdir log_directory: specifies what directory to write logs. -L or --logfile log_file: Specifies log file. --home home_direcotry: Specifies pgxc_ctl work director. -i or --infile input_file: Specifies inptut file. -o or --outfile output_file: Specifies output file. -h or --help: Prints this message and exits. For more deatils, refer to pgxc_ctl reference manual included in postgres-xc reference manual. Please guide me, i am following that demo.txt file which is used in pgxc demo.

No, as much as pgxc_ctl.conf is consistent with current configuration, it's okay.

pgxc_ctl knows new gtm-proxy because he edit pgxc_ctl.conf manually and of course it has entry for gtm-proxy. Do you mean pgxc_ctl has another file to memory about gtm-proxy?

When you use "pgxc_ctl add", you should not edit pgxc_ctl.conf and issue "pgxc_ctl init". This presentation and demonstration materials may help you. * http://sourceforge.net/apps/mediawiki/postgres-xc/index.php?title=PGOpen2013_Postgres_Open_2013 On the other hand if you want to edit pgxc_ctl.conf by yourself, it may be deprecated, you need to issue "CREATE NODE" at each existing coordinators for new coordinator and datanode and also need to issue "CREATE NODE" at coordinator3 for every existing nodes after "pgxc_ctl init". * http://postgres-xc.sourceforge.net/docs/1_1/sql-createnode.html Regards.

Hi Masataka, yeah i have manually edited pgxc_ct.conf file and just added one more gtm_poxy, coordinator and datanode. then deploy node5 init gtm_proxy gtm_pxy3 init coordinator master coord3 init datanode master datanode3 start gtm_proxy gtm_pxy3 start coordinator master coord3 start datanode master datanode3 then add datanode master datanode3 node5 20008 /home/postgres/pgxc/nodes/dn_master isn't it the correct way to add new datanode ? On my real server i have to add number of new nodes later on, so i don't want to get stuck at that time. Please suggest.

I wonder you manually edited your pgxc_ctl.conf and issued "pgxc_ctl init", right? I think you're recommended to use "pgxc_ctl add" for that purpose. "pgxc_ctl add" appends your pgxc_ctl.conf and setup component's configuration files and coordinators' settings. If you want to do it in your way, you must issue "CREATE NODE" SQL commands at your all coordinators after you start coordinators and datanodes. Please notice I'm not sure it is all you have to do.

Please take a look at http://postgres-xc.sourceforge.net/docs/1_1/pgxc-ctl.html Also, when you add restored GTM, you should initialize it as a slave, then fail it over.

Hi Koichi, what command i should use to connect restored GTM to the current master GTM as a slave ? it would be great if you provide me the link for all pgxc_ctl commands, so i can refer it myself.

Something seems went wrong in the first step you added. It says that some coordinator master was not running when you added datanode3. It was half done. To recover this, please try the following. 1) Visit each coordinator and issue "select * from pgxc_ndoe". If you find "datanode3", issue "drop node datanode3" in each coordinator. 2) Make sure that all the coordinators are running. 3) Again, try "add datanode master" command from pgxc_ctl. Please note that you should have all the coordinator running properly when you add datanodes or coordinators.

You should connect restored GTM to the current master GTM as a slave, then fail it over and reconnect GTM proxy to the new one. Failed-over GTM has current cluster transaction status and the new master has to restore its status from the current master GTM.

Hi All, I have pgxc running with 1 master 1 slave , 2 GTM Proxy, 2 Datanode and 2 Coordinator. Now i want to add third component with GTM proxy, datanode and cordinator I have configure third server and deployed binaries (deploy node5) then i have initialized each But when i tried to add third datanode i got below error ERROR: Some of the coordinator masters are not running. Cannot add new one. so i started each component start gtm_proxy gtm_pxy3 start coordinator master coord3 start datanode master datanode3 Now everything is running but i getting below error while executing a query. *koichi=# execute direct on (datanode3) 'select * from t1';* > *ERROR: PGXC Node datanode3: object not defined* > and now if i am trying to add datanode while everything is running , its throws below error: *PGXC add datanode master datanode3 node5 20008 > /home/postgres/pgxc/nodes/dn_master* > *ERROR: Node name datanode3 duplicate*. > Is that flow is correct or i am missing something what steps i should do to make it working ? -- Thanks, Juned Khan iNextrix Technologies Pvt Ltd. www.inextrix.com |

When you fail-over GTM, you should reconnect gym-proxies to the new gtm. This could have been done automatically but now you need to do this annually using reconnect command of pgxc_ctl. When you find gym proxy is down, you can just restart it.

Please take a look at the note I’ve just submitted and let me know what’s going on. It is essential to specify ―prefix option to ./configure to get all the installation material to go to proper place. Also you need to setup your .profile or similar settings to configure your PATH and LD_LIBRARY_PATH to get pgxc binaries and libraries first, not postgreSQL ones. Regards; --- Koichi Suzuki 2014/03/06 15:07、Juned Khan <jkh...@gm...<mailto:jkh...@gm...>> のメール： Hi Koichi, I have installed pgxc by configure, make and make install but the difference is i haven't specified the prefix. then i have created postgres user and given permission to this user. set key-based authentication for this servers. then configured the script according to my need and followed the commands which you have shown in that demo. did i miss something ? Please suggest.

You need to specify the same value of If you don't specify --prefix=/usr/local/pgsql/include/server/pgxc option at configure. After the build is done, run "make install". All the material will go to specified directory. If you did all these, could you please let me know the steps you've done since you get Postgres-XC material?

Please check the following steps: 1) cd to your postgres-xc source directory (at the top) 2) ./configure --prefix=/usr/local/pgsql/include/server/pgxc --enable-debug # this is a good practice to enable this. 3) make 4) make install 5) make sure your pgxc binary went to the directory specified in --prefix option 6) pgxc_ctl --configure (your configuration file) 7) deploy all # invoke within pgxc_ctl You should give write privilege 8) Meke sure that all the binaries are installed in all the target servers. which commandname will show you what binary really runs as commandname command 9) init all # invoke within pgxc_ctl 10) Createdb dbname #invoke within pgxc_ctl, be sure to capitalize the first letter. Please make sure that you've given appropriate privilege to xc installation directory and each database installation directory, specified by gtmMasterDir, cordMasterDirs and DatanodeMasterDirs in each target server respectively.

Please specify "create database", not "createdb". createdb is a shortcut command so you will get an error message.
