Thanks for the information.
For Step5 (starting ensemble daemon).-
I set the multicast address to both nodes (Node 1& Node 2 eth0: 224.0.0.9/4)
before starting the ensemble. And started the server application mtalk in node
1 & node 2 and then client application in node 1 & node 2. But the count of
members ('nmembers') show as 1. This is the output of the client program
'c_mtalk'. Seeing this, I'am assuming that the applications are not merged.
Could you please let me know how did you proceed with the setup of ensemble?
regards,
Niranjan

yeah, actually, i have not been successful to set up this, but let me give some
information for you.
1. download the postgresql snapshot source code from here:
http://www.postgresql.org/ftp/snapshot/dev/
(this is a daily tarball)
2. Get the corresponding patch for postgres-r from:
http://www.postgres-r.org/downloads/
3. apply the patch for snapshot source, and configure like this:
./configure --enable-replication
make & make install
4. install the GCS ensemble, according the document :
http://www.cs.technion.ac.il/dsl/projects/Ensemble/doc.html
5. start ensemble daemon and gossip if neccessary ( yes, make sure the two
nodes can 'GCS' each other)
3. Assume that you have two nodes, start up postgresql and create a database
'db', and create a table 'tb' for testing which should be have a primary key
for all nodes.
4. At the origin node, execute the command at psql console:
alter database db start replication in group gcs; (which means the database
'db' is the origin and the group 'gcs' is the GCS group name)
5. At the subscriber node, execute the command:
alter database db accept replication from group gcs;
Hope information above would be helpful, and keep in touch.
