Mongo db installation showing storage engine error

mongodb

I just installed monodb(version 3.2) at my windows machine. I created /data/db directory also. when i give the command "mongod" to start it, it shows the following error

 exception in initAndListen: 28663 Cannot start server. The default storage engine 'wiredTiger' is not available with this build of mongod. Please specify a different storage engine explicitly, e.g. --storageEngine=mmapv1., terminating

previously I installed version 3.0 but no error like that.
Can any body help me with this?

In there site they are saying that the default storage engine is "wiredTiger" but it has been also said that wired tiger does not work in 32 bit environment. so I wrote in my command line

mongod.exe --storageEngine=mmapv1

to switch to mmapv1(the default storage engine og 3.0 version) and it's working now.

SocketException in Mongo logs

First off, take a look and follow the steps outlined here:

http://www.mongodb.org/display/DOCS/Troubleshooting#Troubleshooting-Socketerrorsinshardedclustersandreplicasets

Next, look for any ulimit issues on the target host (a new file descriptor is required for a new socket and can cause the error):

http://www.mongodb.org/display/DOCS/Too+Many+Open+Files

Finally, there are a couple of issues related to idle connections being used when they should not be, and that can also contribute to this type of issue:

https://jira.mongodb.org/browse/SERVER-5793

Until SERVER-5632 is complete, the only remedy here is to flush the connections by restarting the mongod/mongos processes.

Mongo as service error: Cannot determine state of server

This is an error with the Mongoose driver/ODM.

Try this (taken from the docs):

var uri = "mongodb://username:password@candidate.19.mongolayer.com:10292,candidate.18.mongolayer.com:10292/app25406086"
var options = {
  replset: { rs_name: 'myReplicaSetName' }
}
mongoose.connect(uri, options);
