RPC in the Java Platform

In distributed computing, there is an essential need for the applications in the distributed environment to be able to use the functionalities offered by each application without knowing how these functionalities are implemented. One common possibility for this is the Remote procedure call (RPC), which is an Inter-Proccess communication that allows a computer program to cause a subroutine or procedure to execute in another address space (commonly on another computer on a shared network). Java Remote Method Invocation is the Java implementation of Remote Procedure Call. In the solution for this "Problem", we will take a look at the mechanism of Java RMI.

Slow MySQL execution over Network under Java

If an application and the connected database is developed and tested on one single machine, code optimization and design of queries may suffer due to instant access time and nearly no transfer time between database and application. However, if you put the Application and Database on different machines such design flaws can lead to horrible processing times. There are several fields that may cause problems in that case. One problem is transferring of many records from or to database. Another problem is execution of hundreds of single independent SQL statements in a very short time, where the application always has to wait for response of database.

"Ad hoc" network

"Ad hoc" is a method by which multiple wirelessly enabled devices may communicate without needing a central hub, or base station. It’s not the way most people use Wi-Fi in that it connects computers directly without the need for a router. Instead, ad hoc networks are primarily created for temporary use, as the Latin origin of the term, meaning "for this," implies.

Say you had two laptops out in the field with no connection to the Internet. You could create an ad hoc network between the two to transmit files and share data. Although it is possible to connect to the Internet using an ad hoc network, it is generally used to connect to other devices.

Host Computer:

1) Go to Start and right click on Network and then click Properties.

2) Network and Sharing Center window will appear, click on Set up a connection or network.

3) Set up a connection or network window will appear, select Set up a wireless ad hoc (computer-to-computer) network option, then click Next.
4) Set up a wireless ad hoc network window will appear, this window will briefly explain to you what is ad hoc wireless network. Click Next after the reading.

5) On this wireless network configuration window, you can type in the network name, security type (encryption) and security key. Don’t forget to enable the encryption, if not every nearby computer can connect to this network. Click Next again.

Client Computer

1) Go to Start and click on Connect to.

2) Connect to a network window will appear. This window will show all available connections, which are dial-up, VPN and wireless connections, but your focus is on ad hoc wireless connection. Scroll down the list and select the ad-hoc wireless network and click Connect button.

Et voila:)


Create bridge to connect the netwrok

As the internet connection in dormitory is one network group and the network in the room via network switch is another network, we need the bridge to connect it together so that the other PC in the network via network switch can use the internet. The solution is to create the bridge between the dormitory network that provides the internet connection and the network group via network switch. Then, everyone can use internet.

Synchronize large amounts of Files in heterogeneous (home-) networks

Many people are using notebooks and workstations with different operating systems and want to have all user files perfectly synchronized. There are several options to archive this, which is the best in regards of performance and usability.

Connect the internet from another PC via network switch

I have network switch to connect my PC and my friends' PC together. By the way, the dormitory provides internet connection by only one device that uses USB port. When we want to connect the internet, we have to plug the USB internet connection provided by the dormitory to one PC and use the internet via network switch. But it does not work. Only the PC that connect to the USB internet connection can connect the internet. How to configure it so that Every PC can connect internet via network switch?
