>
>
> Reliable DUCC
> * Support for multiple DUCC head nodes, one of which is the active master the
> others are backups only, with takeover by new master activated by virtual IP
> address switching though keepalived
> * A switch mechanism that potentially is employed by keepalived to determine
> the health of the set of Reliable DUCC head nodes in order to make the
> virtual IP address assignment
> * Autostart capability for head node and agent daemons, whereby administrator
> intervention to issue start_ducc is unnecessary
> See svn branch /uima/uima-ducc/branches/reliable-ducc for development code.
> Reliable DUCC document can be found under
> uima-ducc-duccdocs/target/site/duccbook-pdf/reliable-ducc.pdf after issuing:
> > mvn clean install -Pbuild-duccdocs
