Re: [GENERAL] Postgres High Availablity Solution needed for hot-standby and load balancing
Hi Usama yes, currently I am reading a brochure about Continuent uni/cluster for PostgreSQL. Looks quite interesting. Another product sounds promising: Cybercluster from www.postgres.at English Product Description: http://www.postgresql.at/picts/download/dokumentation/documentation_cybe rcluster.pdf Anyone has made experiences with it? thanks Ragnar From: Usama Dar [mailto:[EMAIL PROTECTED] Sent: Freitag, 30.

[GENERAL] Fault Tolerance & Master-master-Replication Solution needed
Hi, I am searching for a Fault Tolerance & Master-master-Replication Solution which fulfills these requirements Req1) Master master replication supported, not only master / slave replication with only the master being writable. If you do have multiple slave systems they are only useful from a backup and standby perspective. Ad Mo must have a db-connection it can write to. Req2) A plan is needed for deploying changes on the database structure. What needs to be done to apply a change saved into a live db environment? Req3) Not only a warm-standby-solution is needed which is not scalable. Load Balancing is wanted for the future. Do you have experience with Cybercluster or Continuent uni/cluster? Sounds very promising. best regards Ragnar ---(end of broadcast)--- TIP 5: don't forget to increase your free space map settings
