Hi, Using local pg_dump will consume local XID, which may affect the following cluster operation. You may have to give GTM safe GXID value to begin with. It will be safer to simply copy $PGDATA, which will not consume any local XID.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Thanks a lot for reply, Suzuki! I presume that at the moment to recover (fail-back?) a node a following course of action would also be effective: 1. stop the cluster 2. dump the coordinator and datanode dbs, e.g. using pg_dump 3. send the dumps to the node being recovered and recreate coord and datanode using the dumps?

Hi, So far, we can use PITR for individual datanode. Unfortunately, we've not released any utility to set it up. Now we're working to add mirroring capability of datanodes, which allow whole cluster continue to run and maintain cluster integrity even when some mirror fails with disk failure. In this case, mirror can be failed back by stopping whole cluster, copying files from another surviving mirrors and restart the cluster. In the case of coordinator, because all the coordinators are essentially clones, we can continue to run the cluster without the failed coordinator. To fail-back the coordinator, we can copy whole database from another coordinator while the cluster is shut down and restart whole cluster. When a coordinator is failed and is involved in outstanding 2PC, we need to clear it up to prevent them to appear in snapshots for a long time. We're now implemeting this capability. Ideally, it's so nice to have each component failed back without stopping cluster operation. This will be a challenge of this year.

For the answers to your questions... please see inline. About CREATE DATABASE, there is since version 0.9.3 all he necessary mechanisms to synchronize automatically Coordinators (well, DDL...) through the whole cluster. So it is not necessary to resynchronize the catalog files of Coordinators manually. If you are getting snapshots warning when creating a Database, you may have configuration problems. You should double check your configuration files. > I have NOT set up GTM proxy. Do I have to do that? Is it related to my problem? It is not necessary to set up a GTM Proxy to have your cluster working correctly. > Ok, but is the code in git repo stable enough for production use? Code is not stable enough to be used in production, we are currently working a lot on the code stabilization, SQL support and HA features. -- Michael Paquier http://michaelpq.users.sourceforge.net |

Hi Martin, Well I checked this command: git clone git:// postgres-xc.git.sourceforge.net/gitroot/postgres-xc/postgres-xc and it worked well. I also checked if server was online. It looks OK. ping 216.34.181.91 PING 216.34.181.91 (216.34.181.91) 56(84) bytes of data. 64 bytes from 216.34.181.91: icmp_seq=1 ttl=240 time=187 ms 64 bytes from 216.34.181.91: icmp_seq=2 ttl=240 time=189 ms 64 bytes from 216.34.181.91: icmp_seq=3 ttl=240 time=188 ms Perhaps sf servers were not online at the moment you tried to upload the code, or perhaps you have firewall restrictions. Can you ping source forge server correctly?

I think this is related to what Koichi pointed out, that you have to resync the other coordinators. You may just want to use the latest code in the git repository so that you do not need to worry about it.

Hi, I'm afraid you didn't copy coordinator's database to all the other coordinators. In the current available release, DDL is not synchronized to coordinators (synchronized to datanodes, though). To make all the DDL effect avialable, you should stop all the coordinators and statically copy $PGDATA to all the other coordinators to make DDL effect visible. Next release will include DDL synchronization to coordinators.

I install four datanode/coordinator servers (db01, db02, db03, db04, each db
server include datanode and coordinator service) and one gtm server, I try
to install dbt1-pgxc and run build_db.sh in server db01, all things seems
normal.
After then, I can check the dbt1 in server db01:

They are available from sourceforge. Please visit http://sourceforge.net/projects/postgres-xc/files/ You will also find links to individual document from Postgres-XC page http://postgres-xc.sourceforge.net/ Please try "Download" button. BTW, postgres-xc is not stable yet. If you're interested in using it as a production, I think you should wait a bit. Anyway, testing current version will help.

Hi all, In version 9.0.2, it uses the parameter use gtm_coordinator_id or gtm_coord_id? Are they the same? I found it in <PG-XC_InstallManual_v0_9_2.pdf>, it said "gtm_coord_id = i" in coordinatori postgresql.conf configure file, "gtm_coord_id = i+1" in datanodei postgresql.conf configure file, And I found it in <PG-XC_pgbench_Tutorial_v0_9_2.pdf> said "gtm_coordinator_id = 1" for the coordinator1 and "gtm_coordinator_id = 11" for the datanode1. Best wishes, Dika.Ye |

Are you able to connect to a coordinator via psql? Is your pg_hba.conf file ok?
