    I just configure 2 mySQL servers for a MASTER-MASTER replication. I choose the RBR replication for some reason.My congifuration on the server ONE :#replication server-id=1 binlog_do_db = db1 binlog_ignore_db = db2 log-bin=”C:/ProgramData/MySQL/my56″ auto_increment_increment = 2 auto_increment_offset = 1 binlog_format=ROW replicate_do_db=db1and on the server TWO :#replication server-id=2 binlog_do_db = db1 log-bin=”C:/ProgramData/MySQL/my56″ auto_increment_increment = 2 auto_increment_offset = 2

    database postgresql database-replication postgresql-9.1
    I am trying to set up synchronous replication with Postgres 9.1, but I cannot get it to work. I was able to configure streaming replication, but not synchronous. I hope I have not missed anything obvious. I have read carefully many sections of ch 17, 18, 14, 25, 26 and 29 in the admin guide.I am running ubuntu 12.04 and my master postgresql.conf has these, among all the other standard settings:listen_addresses = ‘*’ # what IP address(es) to listen on; wal_level = archive

    We started using Multi-Master Replication Manager for MySQL, and I am wondering whether it is possible to to treat this setup like multi-symmetric processing: a process pops off the process queue, and the node (in this case a server) that is most free is selected for the job.It seems that what happens is, the service switches to a slave ONLY when it mysqld crashes or goes away.Is there a way to make database replication for MySQL act in more of a distributed manner? Maybe there is other software

    In this simple program, I want to reconnect to replica set when the primary node crash. But it doesn’t work: if the primary node crash, this program will be terminated immediately without any output, and return 141. I don’t know why. What is the proper way to reconnect to replica set?#include <stdio.h> #include <mongo.h>int insertVal(mongo *conn, int val) {bson op[1];bson_init(op);bson_append_int(op, “val”, val);bson_finish(op);int status = mongo_insert(conn, “test.vals”, op, NULL);b

    mysql database-replication
    We have a MySQL setup running a single master and two replication slaves. We recently ran into a scenario where SlaveIO had stopped on one of the replication slaves and SlaveSQL had stopped on the other replication slave. This had silently stopped replication on both slave servers. I decided to write a monitoring plugin for Nagios to keep an eye on the status of SlaveIO and SlaveSQL. The problem I am having is emulating the scenarios we ran into above. I can issue a “STOP SLAVE” command to stop

    mysql replication database-replication master-slave
    Here’s the scenario: I have one MySQL Master and 1 slave. master-slave replication is set and works perfectly. The slave machine crashes. The master machine is still up and running. Nothing changes in the master DB. I start the slave machine again. I start the slave MySQL DB.Do I need to invoke “start slave” again on the slave DB ? 10x.

    I’m currently planning a more fault tolerant setup for my organizations Mail setup. We currently have two machines available in different datacenters, that we’re planning to use for this, one being a physical host, the other being an lxc “VM”. The plan is to make the Physical host our primary Mailserver (lets call it server1) and the VM (lets call that server2) the secondary via DNS, so that when server1 goes down, server2 could take over until we’ve got the other one up and running again.As wit

    i have installed mongodb (1.8.3) on two seperate servers and set them up to use “replica sets” as found here: http://www.mongodb.org/display/DOCS/Replica+Set+Tutorialeverything looks good so far: one server is recognized as primary, one as secondary (when i access them via commandline).the problem is that i can’t connect to the DB using node.js (0.4.10) and mongoose (2.1.0) like this:var mongo = require(‘mongoose’); mongo.connectSet(‘mongodb://host/dbname,mongodb://host2/dbname’);i always get th
