[Netarchivesuite-users] Netarchive Suite 3.21.0 MessageQueue and backup questions

[Søren Vejrup Carlsen]

Hi Meelis.
First, we recommend you upgrade to NetarchiveSuite 4.0, the latest stable release with WARC support.
1) About your broker, what version of OpenMQ are you using, and how did it crash? (Lack of memory, or queues filled up). We're currently using OpenMQ 4.5.2. Some apps do (and some don't) reconnect automatically to the JMSbroker. But except for the harvesters, it is not a problem to restart these applications. Most apps read their states from the database, or react on messages from the JMS broker.
2) When we used an embedded Derby database, backup was integrated in NetarchiveSuite. Now when the database in all cases (Derby, PostgreSQL, MySQL) is external, you need to use the tools available for the specific database type.

What database are you using?

Emne: [Netarchivesuite-users] Netarchive Suite 3.21.0 MessageQueue and backup questions

Hi all!

I have two questions about Netarchive Suite with what I hope you can help me with.

1. MessageQueue

Some days ago our MessageQueue crashed and therefore Netarchive Suite applications cannot communicate. I restarted the mqbroker service but NAS does not understand the new instance. So none of the messages go to MessageQueue.
Is there a way to make NAS understand the new instance of mqbroker and continue to work without restarting the whole system? We have some jobs running but heritrix will not end them when they are finished and we have new jobs pending to start thanks to the crash.

2. NAS backup

We are currently working on a backup plan for our archive system and as we have had some issues with NAS database corruption (mainly because of my mistake and testing) we would like to know how to back up the NAS system so if something happens we can just install a new NAS and restore the DB from the backup.
