This is not strictly a debian question but since collectively the
experience here is large I'm hoping someone here may be able to point me
in the right direction.
I have installed opennms 1.2.3-1 on Debian and it has been running
extremely stable for about the last 20 months or so. Adding nodes,
polling for new nodes, managing/unmanaging interfaces, everything was
humming along. Since I was the only one looking at the alarms, etc, I
was never particularly concerned with "tuning" the discovery so that it
would not monitor unnecessary items, nor was I concerned with removing
these items because with a glance I still knew where I had problems.
Several weeks ago that situation changed and I went in to do the
aforementioned tuning. ie, removing networks from discover, deleting
nodes that did not need to be monitored, unmanaging interfaces that were
no longer in use, enabling snmp on all nodes so that opennms could make
heads or tails of what was a router and thus group interfaces properly.
This all seemed to work great and I went about my business. However
this week I have discovered that I cannot delete nodes any longer, nor
can I add new nodes. I have done some digging in the opennms database
and it appears that the node table is locked and will not allow new
entries or allow deletion of existing entries. I am not an expert on
postgresql by any stretch but I have tried the following command and it
just hangs
delete from node where nodeid=19;
I can ctrl-c out of this so the command isn't hung, it just doesn't
appear to be getting a response from the db engine. A similar command
worked to delete obsolete interfaces from the ifservices table (one node
in particular had 3700 entries with an IP address of 0.0.0.0 - not sure
where those came from but it is probably related).
Finally, once and if I get this issue fixed I need to go into the events
table and delete all history prior to 10/1/2006. This is basic sql
stuff so if someone has a good sql reference that they can point me to,
I would appreciate that.
Thanks for your help.
