主题: [Postgres-xc-general] Postgres-XC 0.9.3 is now available

Postgres-XC development team is pleased to announce that Postgres-XC
Version 0.9.3 is now available.

Major additional features include:

Transparent DDL.   Now DDL is automatically propagated to all the
coordinators and data nodes.
General SQL support:  Statements may include cross node joins.
Extended protocol support for libpq:  This is needed to use
Postgres-XC from Java.
Cursor support: This is also needed by Java and other languages.
Global Timestamp:  Timestamps are now supplied by GTM.

This version includes many bug fixes and is much more stable than
previous ones.   We've tested DBT-1 benchmark for one week with 90% of
full load.   The test ran stably without any error in DBT-1.

You can download the release from Postgres-XC project page:
https://sourceforge.net/projects/postgres-xc/
General information is available in Project page:

主题: Re: [Postgres-xc-general] 答复: gtm_coordinator_id or gtm_coord_id

 

Hi Dika,

You can get the latest code from the project's GIT repository.
GIT is a CVS system.
Install it and then take the head code with this git URL.
git://postgres-xc.git.sourceforge.net/gitroot/postgres-xc/postgres-xc

You can create a GIT repository with the following commands:
mkdir pgxc
cd pgxc
git init
git remote add pgxc
git://postgres-xc.git.sourceforge.net/gitroot/postgres-xc/postgres-xc
#Upload code to your local machine
git fetch pgxc
git branch --track master pgxc/master
#extract branch master on your local machine
git checkout master

If you want to install GIT, have a look at their website
http://git-scm.com/.
They have also some documentation here http://git-scm.com/documentation.

I also compiled a small manual here, I believe it is helpful.

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.

Also, just to clarify, Postgres-XC does not use multi-master 
replication. The term "multi-master" is meant in the sense of 
"multi-head", that you can connect to anyone of the multiple 
coordinators and get the same consistent view of the data. We may update 
the web pages to clarify this.

Mason

As Koichi mentioned, no it is not ready for production use. We encourage 
you to try it out in a test environment and provide feedback. In 
addition, if you have a specific application in mind that would make for 
a good pilot project, feel free to contact me directly, as we may be 
willing to change development priorities so that XC can meet your needs 
and we have a good case study.

Thanks,

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:

################# cut here ########################

[root@db01 pgsql]# /usr/local/pgsql/bin/psql -p 5432 -d DBT1 -U postgres   

The session started: 7541

psql (8.4.3)

Type "help" for help.

But I can't check dbt1 in server db02 or others:

You will also find links to individual document from Postgres-XC page

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



 

pg_hba.conf has been config as allow all all 172.22.5.0/24 trust.
psql works fine to create table and insert data.

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

Yes.    We're planning to upgrade the base version to 9.0.1 (just
released) by the end of next March.   Until then, we will concentrate
on extending coordinator and data node to support wider range of the
statement, as well as HA capability.

Eg: EDB 8.4 version or postgresql 9.0??

Dear All

I have installed postgres-XC 0.9.2 version with single node.

I met some problem with trying to use pgadmin to connect database from coordinate but it is sucess to connect from datanode.

pgadmin is just hanging there.

 

startup command is blow:
