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

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

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 ??

Best Solution

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.
