how to deploy new app jar?

["Zach A. Thomas" <za...@aeroplanesoftware.com>]

Hi, everyone. I'm a committer on the Sakai 3 project, which we're building on top of Sling.

We use a modified version of Sling's Launchpad App. Essentially, it's Sling plus a lot of additional bundles.

While I'm doing development, I may end up with a new app jar several times a day. When I'm working on my own machine, I can simply stop Sling, blow away the sling directory, and run the new jar. However, we now have a staging environment at NYU which uses Oracle as the Jackrabbit store, and when I want to roll out a new app jar, I'd rather not drop the whole database if I don't have to. When we go to production, dropping the database will (understandably) no longer make sense.

I have no trouble using the Felix console to update bundles one-by-one, but is there a good way to update _all_ the bundles in the Launchpad App without dropping all my database tables? Bringing down the server is ok.

many thanks,

Do you know if that's heap memory issues, or PermGen?

Our project (Sakai) has about 100 of its own bundles.  Using
maven-sling-plugin works for a small number of bundles but trying to update
this many bundles at once on a live server has shown terrible memory issues
for us.

Is there a 'best practices' way to do full application updates like this in
a running or downed server?

The maven-sling-plugin can install bundles, so if you run a maven
reactor build that activates it you should be able to update all your
bundles at once.

See the autoInstallBundle profile in the Sling parent pom [1] for an example.
