Nothing on queues, Journal files not getting cleaned up
Hello,
How is it that our journal files continue to grow, yet no messages are on the queues?
ActiveMQ 5.11.1, Using KahaDB (not levelDB).
How can you tell if a kahaDB scheduler is waiting, and in need of clearing?
Nothing on the Advisory queues (no network of brokers), nothing on the DLQ. Where else can I look? Our txlogs are very large as well. Application Teams advise their transaction processing IS committing on gets and puts, etc..
Regards,
Barry
RE: Nothing on queues, Journal files not getting cleaned up
Posted by ba...@wellsfargo.com.
I did find something, but need some advice:
We are using ActiveMQ 5.11.1 in our environments.
The behaviour we noticed was that ActiveMQ wrote the messages to a new kahadb file (journal log) after every 32 mb (default configuration). This lead to the message and its corresponding ack ending up in different files. It resulted in a chain of such journal logs which couldn't be cleaned up by ActiveMQ. It eventually filled up the disk causing ActiveMQ to shutdown.
Is it a good idea to increase the log size to avoid having the message and its ACK in different files? Any suggestions here?
Regards,
Barry

I trust you've confirmed that there are no messages pending on topics as
well as queues? JMX is the easiest way I know to confirm that if you
haven't already done so.
Are some but not all journal files being deleted, or none at all?

But if the message and its ACK are in different files due to high volumes, and cleanup is not occurring due to this, wouldn't you want to increase file size from 32mb?

Isn't there any option to compact the journals on activemq5?
In a journal sometimes you have the add-delete-add-add-delete somehow that you can't can't really clean it unless you compact the whole thing. Most of the times I had this issue was because I had a pending TX or something.
Also: is there any pending XA Transactions?

What if the problem isn't with messages being consumed at different times? What if they all are being consumed right away but yet the journal files continue to grow?

There is no option to compact KahaDB. The current solution for the problem of journal files not being cleaned up is to use multi kahadb. Gary has a good post about it here http://blog.garytully.com/2011/11/activemq-multiple-kahadb-instances.html
There's a couple open tickets to add compaction to KahaDB.

Re: Nothing on queues, Journal files not getting cleaned up
Posted by Tim Bain <tb...@alumni.duke.edu>.
One other thing about chains of KahaDB files: they can only occur when
you've got unacked messages. If you have a chain of files, and you think
you have no unacked messages, then you're wrong and you need to figure out
where the message actually is. You sent some emails yesterday saying
you've got KahaDB journal chains and some saying txlog was your issue, and
it wasn't clear if the later messages meant "I was mistaken, there's no
chain after all" or "we have both chains of journal files and large txlog
files", but if you have chains of journal files, you probably don't have
zero unconsumed messages.

Re: Nothing on queues, Journal files not getting cleaned up

If anything, you want smaller files not bigger ones, because you're hoping
for a situation where for a given file, all of the messages in the file
have their acks in the same file. If that happens (and it's pure luck of
the draw), you break the chain of having to keep newer files because they
ack messages in older files, and you'll then be able to delete the later
files once all their messages are consumed. The more boundaries between
files there are, the more places where you have a shot at that happening,
so more smaller files increases your odds (but never guarantees anything).
But you're right that all of the above doesn't sound like a solution to
your problem, because it sounds like it's your txlog that's your problem,
not the KahaDB journal files.
Unfortunately I know nothing at all about those files (I've never used
transactions with ActiveMQ), but I know others on here have and hopefully
one of them will have some advice to give.

Why would the txlog (transaction log) be constantly growing with no messages on the queues? This is taking up all of our disk space, not the kahadb journal files!
Are there any howl log settings we should be using aside from the defaults?

In a journal sometimes you have the add-delete-add-add-delete somehow that
you can't can't really clean it unless you compact the whole thing. Most of
the times I had this issue was because I had a pending TX or something.
Also: is there any pending XA Transactions?
