Hi chaps,
I've noticed a problem as described below with regards to adding
replication
sets from within pgAdmin. I originally posted on the slony I general
list,
and Christopher Browne suggested I ask you guys.
I set up a replication cluster using the pgAdmin scripts, and added a
replication set with some tables and sequences in it (table /sequence
Ids 1 - 4). I've kept the Id numbers the same as the table Ids.
Then I added another set (Id 2), and added a table and a sequence
with Id 5.
In my slony log I get the error:
"remoteWorkerThread_1: node -1 not found in runtime configuration"
Does anyone know what causes the error above? I've read that it
indicates slony had a problem at a point whilst subscribing so it
flipped the node number to -1 to stop any further steps happening,
however this doesn't help me track down what caused it.
No "drop set" option seems to exist from with pgAdmin (although I'm
pretty sure I saw it once - are their criteria that make it appear?),
so I did a "DROP SET ( ID=2, ORIGIN=1 );" using slonik on the origin,
and
the set was removed from the origin, but it's still visible
(using pgadmin) on the subscriber (I have restarted the slons).
I notice this error occours periodically now in the slony
logs, so it seems the subscriber is trying to subscribe it? E.g.
------------------------------------------------------
2008-01-15_144529 GMT DEBUG2 syncThread: new sl_action_seq 1 - SYNC
38491
2008-01-15_144533 GMT DEBUG1 copy_set 2
2008-01-15_144533 GMT ERROR remoteWorkerThread_1: node -1 not found
in runtime configuration
2008-01-15_144533 GMT WARN remoteWorkerThread_1: data copy for set
2 failed - sleep 60 seconds
WARNING: there is no transaction in progress
------------------------------------------------------
How do I remove this set from the subscriber?
I've had this happen before. Removing the cluster and setting it up
again resolves the problem, however once we are in a production
environment I can't go dropping the whole cluster and replicating all
the tables from scratch when it happens.
Any pointers would be greatly appreciated
Glyn
