Re: High Avaliable in the PostgreSQL.

[adey <adey11(at)gmail(dot)com>]

HP was providing CA (Continuous Access) software that was claimed to provide WAN SAN replication by repeating IO in exactly the sequence it was generated on the master, to the slave. SO while there was a delay, updates on the slave would be sequentially intact, providing a good level of integrity for database rollback on the slave in the event of recovery on the slave / DR system. I'm not sure this would be sufficient for 
99.9% uptime though, as there would be some startup requirements on the slave.

Hi,


       I need solution to PostgreSQL for High Available, originally
was 99,7% but considering the current necessities, change percentual
to 99,99%. I think in solution probability  pgpool-2 or Heartbeat +
GFS. The PostgreSQL servers will be in different physical places.

       Suggestions?
