Yes, it should work.    It may avoid any other problem if you invoke
this command within pgxc_ctl, not command parameter.

pgxc_ctl
PGXC add coordinator master coord3 node5 20004 20010
/home/postgres/pgxc/nodes/coord

Thanks,

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.


Coordinator Master:

It is due to misconfigure. In detail, numbers of element for same

Hi Koichi,Masataka

Successfully added *gtm* proxy but having issue with coordinator and
datanode.

*Coordinator :*
*Syntax *: add coordinator master name host port pooler dir
here what value i should use in place of pooler ? pooler port ?

*Command* : pgxc_ctl add coordinator master coord3 node5 20004 20010
/home/postgres/pgxc/nodes/coord
ERROR: sorry found some inconflicts in coordinator master configuration.

pgxc_ctl add coordinator master coord3 node5 20004
/home/postgres/pgxc/nodes/coord
ERROR: please specify the working director for the coordinator master

*Datanode :*
*Syntax :* add datanode master name host port dir
*Command :* pgxc_ctl add datanode master new node5 20008
/home/postgres/pgxc/nodes/dn_master
 ERROR: sorry found some inconflicts in datanode master configuration.

Does earlier manual installation could be reason for this issue ?

*P.S:*
*gtm_prxy* : Nodename: 'gtm_pxy3', port: 20001, dir:
'/home/postgres/pgxc/nodes/gtm_pxy'
*Coordinator Master*: Nodename: 'coord3', port: 20004, pooler port: 20010,
dir:' /home/postgres/pgxc/nodes/coord'
*Datanode Master* :   Nodename: 'datanode3', port: 20008, dir:'
/home/postgres/pgxc/nodes/dn_master'

please look at my commands if its erroneous

Please advice.

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.

CREATE NODE and DROP NODE only run locally. Why not ALTER NODE for
consistency? Am I missing smth?

As far as I know, the local node information is not important and it
is not necessary to update.
"pgxc_ctl add" corrects it by "ALTER NODE".

Please check your pg_hba.conf and call pgxc_pool_reload().

"pgxc_ctl add" does these of a bother automatically and we are
needless to remember the procedure.

That's funny, I always thought that ALTER NODE ran only on the local
node to make configuration of cluster flexible.

Hi Koichi, Masataka,

With ALTER query it throws

Do "ALTER NODE".   Document will be found at
http://postgres-xc.sourceforge.net/docs/1_1/sql-alternode.html

I'm afraid you're struggling to find pgxc_ctl documentation.   Please
visit http://postgres-xc.sourceforge.net/docs/1_1/pgxc-ctl.html

Hi Masataka,

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

Now its look like this:

postgres=# \q
PGXC Psql -dpostgres -h node5 -p 20004
Selected coord3.
postgres=# select * from pgxc_node;
 node_name | node_type | node_port | node_host | nodeis_primary |
nodeis_preferred |   node_id
-----------+-----------+-----------+-----------+----------------+------------------+-------------
 coord3    | C         |      5432 | localhost | f              |
f                |  1638403545
 coord1    | C         |     20004 | node3     | f              |
f                |  1885696643
 coord2    | C         |     20005 | node4     | f              |
f                | -1197102633
 datanode1 | D         |     20008 | node3     | f              |
f                |   888802358
 datanode2 | D         |     20009 | node4     | f              |
f                |  -905831925
 datanode3 | D         |     20008 | node5     | f              |
f                | -1894792127
(6 rows)

Here coord3 runs on *5432* which should *20004*., it creates problem i
think isn't it ?

if yes then how alter this entry  ?

i am getting *Failed to get pooled connections*
koichi=# execute direct on (datanode3) 'select * from t1';
ERROR:  Failed to get pooled connections

Regards
Juned Khan

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.

It's not a good idea to have gym-proxy not known to pgxc_ctl.   You
should configure gym-proxy using pgxc_ctl.

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".

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.

Regards

Juned Khan
