Bingo! Thank you very much. I ran git remote rm pgxc (rm my previous
remote attempt), then ran your command.
It appears that for some reason --tags option (possibly when combined
with -m) causes a problem with fetching remote branches.

Much appreciated,

This quantity of data looks correct, half of it being due to the data in
doc-xc/.

$ git remote set-branches --add master pgxc/master
> fatal: No such remote 'master'

I am not a GIT specialist, but in order to get all the branches, do only
that:
git remote add -f pgxc git://
postgres-xc.git.sourceforge.net/gitroot/postgres-xc/postgres-xc

You will be able to see all the remote branches available with "git branch
-a"
In this case, remote branches will be listed as remotes/pgxc/master,
remotes/pgxc/REL1_0_STABLE, or whatever.

Then checkout a branch, here master, with that:
git branch --track pgxc-master pgxc/master
git checkout pgxc-master
This will create a branch called pgxc-master set to track the remote PGXC
master branch when doing a git pull on this branch. Replace pgxc-master by
the name you wish.

I just tried the following:

$ git remote set-branches --add master pgxc/master
fatal: No such remote 'master'

??

Here's what I just tried:

cd postgresql.git/
git remote add -f --tags -m master pgxc
git://postgres-xc.git.sourceforge.net/gitroot/postgres-xc/postgres-xc
# this resulted in only 8.6MiB download just now,
# on an up-to-date pg.git repo.

#view results:
git remote -v
git branch -a

In my case, remotes/pgxc/HEAD is the only pgxc 'branch' so it appears
I'm not quite doing something right. Looking at the repo summary page
at:
http://postgres-xc.git.sourceforge.net/git/gitweb.cgi?p=postgres-xc/postgres-xc;a=summary
suggests that there are a number of 'heads' which I assume are branches.
My ~/.gitconfig only has user name and email, so nothing there should
be stopping the branches from being downloaded.

I guess I'm missing something in my command above. From my reading of
man git-remote it should do the trick...

Anyone know what's wrong with it?

TIA
Zenaan

fyi..

PG and PGXC share 99.9% of a common commit history, so yes simply adding a
remote to PGXC in your existing PG folder is good. This is how I do for my
own dev, and I believe that most of the people in this project do the same.
Doing that is particularly helpful when you want to merge PG code directly
in XC or when you need to have a look at the code diffs between both
projects.

Yes, this ML is not a right place to discuss this.

I have my personal project below.

git://github.com/koichi-szk/PGXC-Tools.git

You will find pgx_ctl, with bash script ans its manual.   I hope they
provide sufficient information to configure your XC cluster.

Good luck.

Hi Abel,
WIth the information you have provided, it's not possible to find the
correct cause. You will need to provide detailed steps. Generally speaking,
you might have missed some argument specifying the node to be booted is
coordinator OR you might be connecting to datanode expecting it to be a
coordinator. There are any number of possibilities.

which is the steps to install more than 2 coordinators and DataNodes on 
different machines, I am setting like this website 
http://postgresxc.wikia.com/wiki/Real_Server_configuration

I'm working with debian 6

after configure I receive the following message:

This is a minor release with only bug fixes. You need to wait for the next
major release, normally 1.1, to get this support. Btw, the feature has been
committed on master branch, so you can already test it by fetching latest
development code.

Hi all,

Is there a changelog? I wanted to know if RETURNING support is merged 
into this version.

Ah, sorry. I just added the tag.

Also I apologize that I pushed many old tags onto the branch
which generates lots of commit mails.

Postgres-XC development group release postgres-xc 1.0.2 with a bunch
of fixes/improvement as well as upgrade the base code to PostgreSQL
9.1.7.

You will find resources at:
http://postgres-xc.sourceforge.net/
http://postgres-xc.sourceforge.net/docs/
https://sourceforge.net/projects/postgres-xc/files/Version_1.0/

Upgrading base PostgreSQL version to 9.2 will be included in the next
major release.

Postgres-XC is a symmetric PostgreSQL cluster which provides both read
and write scalability using mixture of table sharding and replication.

Each Postgres-XC cluster node provides single database view, where
application can connect to any cluster node and run any transactions.
Result of transactions are visible from all the cluster nodes without
delay.

Thanks.    So for the master, you don't need any modification to Makefile?   Then the rest of the patch is essentially idential.

Okay, I will test and commit them.

Hi Suzuki-san,

I already submitted two patches on this thread. The first patch
applies to PGXC 1.0. The second patch applies to master. Apologies for
the confusion on the names.

I am re-attaching both the patches with proper names again to this mail.

I tried to apply the patch to the master.    Issues are:

1. gtm_ctl directry was moved to src/bin/gtm_ctl --> patch includes
directory src/gtm/main and src/gtm/proxy so -p option of the patch
does not work here.   Need to edit the patch directly to apply.
2. Makefile at gtm_ctl is rejected.

1. is not an issue.

Nikhil, could you provide Makefile diffs for the master (I don't think
we need other changes to it) ?

Thanks.   I will test this with 1.0 and see if it is applicable to
master as well.   I hope it is :-)

Appreciate for fixing app name for gtm_standby too.

Talk about barking up the wrong tree ;)

I was working with PGXC 1.0 tree. So the earlier sent out patch
applies against it.

PFA, another patch which applies against MASTER.

Additionally I also fixed a bug in invoking gtm_standby via gtm_ctl.
It would blindly append gtm_standby as the name for the binary to
invoke.

Hi,

PFA, patch which fixes this issue in the master git repo.

The behavior is now similar to pg_ctl. Additionally the version
checking was missing in gtm_ctl, gtm and gtm_proxy. I added the same
as well. The binaries will be checked for version compatibility as
well now which is always a good thing.

Nice trick !

But too complex for my brain :) ( i don't understand why tab2 is distributed by replication)

What do you think about that (possible new feature ?) :

-          Possibility to create group like :

CREATE GROUPSERVER group1 ('serverA','serverB');

CREATE GROUPSERVER group2 ('serverC','serverD');
This already exists and is called GROUP NODE, have a look here:
http://postgres-xc.github.com/1_0/sql-createnodegroup.html




-          Possibility to table distributed an replicated like :

CREATE TABLE tab (col1 int, col2 int) DISTRIBUTE BY HASH(col1) ON GROUPSERVER 'group1' AND REPLICATE ON GROUPSERVER 'group2';

                If one of these groupserver have not the same number of server, we have a warning message like that : "WARNING : GROUPSERVER groupX has not the same number of server of GROUPSERVER groupY, so we can't distribute by hash, modulo  or RR but the replication on GROUPSERVER groupY is done."


This is like raid10 for hdd the table is splited between serverA and serverB and mirrored on serverC and serverD. If serverA or serverB or serverA and serverB fail, the table is still available with serverC and serverD .

Is it possible ?
Not now. At least the trick I gave before works the same with vanilla Postgres...
This feature is a little bit too premature with existing XC infrastructure. Such complex things would be possible by first reworking the partitioning of XC to make it more integrated with Postgres I think.
