I guess the above approach is fine if you have basic requirements
from a
repository manager and are willing to go for one that:
- Treats artifacts as just files, discarding any extra metadata that
cannot
be maintained using the file system, such as: who deployed an
artifact, how
many times it has been downloaded, inter-artifact dependencies etc.
We don't discard any artifact metadata. That doesn't need to be stored
in a database.
- Does not need security and therefore does not have to deal with
storage of
ACLs.
Having security is not predicated on using a database, and we'll
demonstrate that.
- Does not need atomic/transactional deployments and/or concurrency
controls
and willing to live with the chance of being left with half baked
deployments.
Also not true. We'll also demonstrate this, but there's nothing you
can do right now because the problem is on the Maven side where there
is no atomic semantics so it's a two pronged approach for correct
operation. We're working on the Maven side and the repository manager
side to make sure it's simple, file-based, and safe.
BTW, the latest Artifactory achieves HA by using *only* DB
replication (not
a combination of DB and FS). HA and ACID usually go together and
Artifactory
is doing it.

It's twice as hard then simply replicating a file system. Try in a
large organization getting DBAs and the sysadmins synced up. It's
just
easier replicating the filesystem. Less moving parts equals better.

I know Archiva is run on a JCR (JackRabbit) repository. I've setup a
Jackrabbit cluster on a clustered oracle database. (So twice
clustering, one for the repo, one for the db). I think it shouldn't
be too hard to implement this with Archiva also.

Not Archiva but Nexus where the disk uses Raid 5 which is then a
network mount. The data and artifacts are shared between two
instances of Nexus and they sit behind a VIP. If the primary goes
down then the VIP flips over to the second instance that's running.
With Nexus it's simple disk replication so you could do lower tech
solutions using rsync, or not so low tech as there are tools that
do disk replication at near wire speeds. But the VIP approach has
worked for us.

Hi all,
Does anyone have experience in setting up Archiva in a highly
available manner? What is the best considered approach for doing
this? Is it possible to replicate deployments to a server across
all other servers in a cluster? Are there any options for
automatic failover?
Any advice or pointers on this would be greatly appreciated.
Kind Regards,
Matt T
