Hello,
I tring to set up Slony replication and am having issues with
repeatability.
Configuration: 2 nodes
Slony ver.: 1.2.6
OS: SuSE Linux 9.2
About 1/3 of the time, replication does not start properly. I think
I've traced it down to the fact that sometimes the second node is not
created properly in the prime db. I can see this by querying the
sl_node table where only 1 node (the prime) appears. On the backup
db, both nodes appear properly. To create the node, I'm using the
following slonik script
try {
echo 'Storing node 2';
store node (id = 2, comment = 'Node 2');
}
on error {
echo 'Could not create Node 2!';
exit -1;
}
No error is thrown when this code is ran, so as far as slonik script
is concerned everything is OK.
Questions:
1) What could be causing the second node to fail to be created? If
this is a timing issue, is there an event, or some data, I could check
to make sure that the 2nd node is ready to be created?
2) I discover that this error has occured after Slony is started on
both servers, and the replication set is subscribed to. If I have to
recreate this 2nd node on the prime server, what do I have to do?
Thank you,
Slawek
