RE: [JBoss-dev] RE: Clustering tasks - TreeCache
HAJNDI could use it rather than the current mechanism of subclassing the non-clustered naming service with replication via direct use of the cluster rpc mechanism. Its something to consider.

RE: [JBoss-dev] RE: Clustering tasks - TreeCache
The ejb container will potentially use TreeCache as its cache policy implementation. This should be the default cache policy in the near future.

RE: [JBoss-dev] RE: Clustering tasks
Some of them are already there, some not, but in 4.0 they should all be there with easy configuration syntax: - asych vs synch - immediate vs time-based - granularity: session, attribute, AOP-liked (field-based) - transparent (or pre-defined) sub-cluster (brother-nodes) replication (when you have 5 nodes, you don't want each node to replicate to the four others) - base code is there, integration is missing - state startup: when a new node starts, should it pre-replicate the state of its brother-node or not - cluster-wide, http-concurrent-requests-for-same-session handling scheme. > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On > Behalf Of Ivelin Ivanov > Sent: lundi, 22. décembre 2003 05:22 > To: [EMAIL PROTECTED]; [EMAIL PROTECTED] > Subject: [JBoss-dev] RE: Clustering tasks > > > Can Sacha or somebody explain what the various http > replication schemes are ? > > >Sacha: - sexy httpsession replication schemes > > Ivelin > > > > --- > This SF.net email is sponsored by: IBM Linux Tutorials. > Become an expert in LINUX or just sharpen your skills.
