commit d7ca431066efe320107581186ab853b28fa5f7a7
Author: Michael P <mic...@us...>
Date: Thu Jul 22 08:59:07 2010 +0900
Support for cold synchronization of catalog table of coordinator.
This cold solution is temporary.
Hot synchronization will be introduced in one of Postgres-XC's next release.
Cold synchronization method means that once a DDL is launched, all the coordinators are stopped.
And then the catalog copy begins from a coordinator chosen by the user.
It is also possible to synchronize catalogs without launching a DDL file on one coordinator.
Options possible to use for this script
-D locate the data folder, necessary to find pgxc.conf, containing the characteristics of all the coordinators
-l to locate the folder where applications are
-f for a DDL file
-d for a Database name
-n coordinator number where to launch DDl, number based on the one written in pgxc.conf
-t base name of folder where to save configuration files, by default /tmp/pgxc_config, completed by $$
Synchronization uses a new configuration file called pgxc.conf gathering all the coordinator data,
such as port number, data folder and host for each one.
Please refer to Postgres-XC 0.9.2 reference manual for further details.
