I have a fast Windows 7 PC with 8Gb RAM. I want to test this MongoDB replica set: http://www.mongodb.org/display/DOCS/Replica+Sets for my development. I dont want to buy 3 PCs though, as it's kind of expensive. Is there a way to use some kind of technology, like Hyper-V, to be able to set it up? If not, how many PC and what kind should I buy?
If you are running MongoDB on production environment it is essential that you setup a real time replication of your primary instance. Using replica set, you can also scale horizontally and distribute the read load across multiple mongodb nodes. This tutorial explains in detail on how to setup MongoDB replication.
Occasionally, when troubleshooting the health of a replica set, I'd like to filter out the heartbeat packets specifically, track them going out, and the subsequent reply (or lack thereof) without all the noise of the other data that is flowing between the sets.
Unfortunately, these packets are structured in much the same way as normal commands/queries and responses.
Hi, I am running a MongoDB replica set on Azure and have connected to it remotely from within an Android app. I've gotten reads to work great from all instances. But, writes to the database still have intermittent errors with the following error. Also, if you could provide any more specific resources for dealing with this issue, then that would be very helpful too.

I'm trying to set up an PostgreSQL database on Amazon RDS as a replica to another PostgreSQL database that lives on a regular server. Most of the instructions I've found online require shell access so that you can copy over a bunch of data files that can't be manipulated through the psql shell.
Amazon RDS for PostgreSQL does not provide shell access, so these methods won't work.
