Subject looking for a Jackrabbit consultant
Date Fri, 13 Jul 2012 14:30:38 GMT
We're potentially in the market for some Jackrabbit consulting help.  We're currently architecting
a site with high-performance/high-availability requirements.  In a previous project, we implemented
a CMS based on Jackrabbit using an Oracle repository operating in clustered mode (version
2.2.1).  Although it works for the most part, we do see occasional issues in two areas:
1.      A cluster node will stop processing revisions.
2.      Since our administrative application runs on multiple servers for HA, we have seen
race conditions where cluster nodes may get nodes with different state - assume due to normal
cluster sync latency and the fact that there's no way to get a cluster-wide lock due to JCR-1173.

Although #1 may be fixed in later versions, it appears to be fundamentally problematic to
try to run CMS applications in separate cluster nodes.  We're interested in getting some help
with architecting a solution that:
*       Eliminates these problems.
*       Provides for high-availability for applications doing both read/write (admin) and
read-only access to the repo.

Pointers welcome - thanks.
