We are using Mongo DB in our Application . We have one primary and one secondary for this purpose .

How can i make sure that my Application is reading data from Primary Or Secondary ??

My question is how can i know if slaveOk=true is set or not ??

Thanks in advance .

Edited Part

Not sure of the Driver what i am uisng I am connecting Mongo DB through Java as shown

ServerAddress addr = new ServerAddress(new InetSocketAddress(host, port));
servAddrList.add(addr);
}
MongoOptions options = new MongoOptions();
options.autoConnectRetry = true;
options.connectionsPerHost = Config.intParam(
"mongo.connectionsPerHost", 1200);      
mongo = new Mongo("10.11.13.111", 27017);

And i am using mongo 2.4.jar

Please let m know how can i find what driver i am using ??

Answer 1

What are you looking for in my opinion is readPreference : http://docs.mongodb.org/manual/applications/replication/#replica-set-read-preference

In the api ( http://api.mongodb.org/java/2.10.1/com/mongodb/ReadPreference.html ) documentation there is an isSlaveOk() method : http://api.mongodb.org/java/2.10.1/com/mongodb/ReadPreference.html#isSlaveOk()

See this question: How to perform read operations from primary only

There is the answer for setting read preference

mongo.setReadPreference(ReadPreference.primary());

and your answer is to get read preference:

mongo.getReadPreference().isSlaveOk();

Unfortunately these features do not exist in versions after 2.4.

Answer 2

looks like earlier java driver just have mongo.slaveOk() method, call it and it is slaveOk. no way to examine.
