The redis-py client provides two classes StrictRedis and Redis to establish a basic connection to a Redis database. The Redis class is provided for backwards compatibility and new projects should use the StrictRedis class.
One of the recommended ways to establish a connection, is to define the con...
No Mutual SSL
In this example, we might use the CA File (ca.pem) that you generated during the "How to configure a ReplicaSet to support TLS/SSL?" section. We will assume that the CA file is located in your current folder.
We will assume that your 3 nodes are running on mongo1:27017, mon...
Like iOS where you use @IBOutlet and @IBAction, here you could use them too.
Let's say we have a button which when clicked changes the label's text to something else.
To get started:

This is the simplest way to connect.
First, the driver has to be registered with java.sql.DriverManager so that it knows which class to use.
This is done by loading the driver class, typically with java.lang.Class.forname(<driver class name>).

Instead of specifying connection parameters like user and password (see a complete list here) in the URL or a separate parameters, you can pack them into a java.util.Properties object:

It is common to use javax.sql.DataSource with JNDI in application server containers, where you register a data source under a name and look it up whenever you need a connection.
This is code that demonstrates how data sources work:

Using a Pool
Most code will want to connect to Redis using a pool of shared connection objects. Connecting to Redis using a pool involves two different code block. At initialization time, your application needs to create the connection pool:
JedisPoolConfig poolCfg = new JedisPoolConfig();
...
MongoClient.connect('mongodb://localhost:27017/myNewDB',function (err,db) {
if(err)
console.log("Unable to connect DB. Error: " + err)
else
console.log('Connected to DB');
db.close();
});
myNewDB is DB name, if it does not exists in database then it...

Signals can have a default handler. All you need to do is to give it a body when you declare it.
public class Emitter : Object {
public signal void my_signal () {
print ("Hello from the default handler!\n");
}
}
This handler will always be called after the connected...
We will start with creating a simple node application with a basic structure and then connecting with local sql server database and performing some queries on that database.
Step 1: Create a directory/folder by the name of project which you intent to create. Initialize a node application using npm ...
