What Is a Service? a Windows Service Is an Application That Usually
What is a service? A Windows service is an application that usually provides a basic Windows function such as manage system memory, make and monitor network connections, play sound, provide a file system, control security and authentication, interact with the user and many more. They run in the background and have has no user interface. Services are always running, whether they are needed or not. Think about setting these to Manual • Bluetooth Services (2): If you don't connect Bluetooth devices to your computer • Connected End User Experience and Telemetry: Microsoft Keyboard Logger • Diagnostic Policy Service: If you don't depend on Windows diagnostics • Distributed Link Tracking Client: When was the last time you created a symbolic link to a shared file? • dmwappushsvc: Transmits keyboard logger data to Microsoft. • Downloaded Maps Manager: If you use any other map service than the Maps app. • Fax: Not needed for printer fax machines, or if you don't have a fax. • IP Helper: IPV6 to IPV4 tools • Print Spooler: If you don't have a printer • Remote Access Connection Manager: If you don't use a VPN or access your home system remotely • TCP/IP NetBIOS Helper: If you are not in a workgroup network • Touch Keyboard and Handwriting Panel Service: If you don't need the screen touch keyboard or the handwriting features • Windows Media Player Network Sharing Service: Shares music across the home network • Windows Defender (4): If you use another antivirus program • Windows Image Acquisition: If you don't have a scanner • Windows Update: If you want to control the update process. -

Unix / Linux Processes Management
UUNNIIXX // LLIINNUUXX -- PPRROOCCEESSSSEESS MMAANNAAGGEEMMEENNTT http://www.tutorialspoint.com/unix/unix-processes.htm Copyright © tutorialspoint.com Advertisements In this chapter, we will discuss in detail about process management in Unix. When you execute a program on your Unix system, the system creates a special environment for that program. This environment contains everything needed for the system to run the program as if no other program were running on the system. Whenever you issue a command in Unix, it creates, or starts, a new process. When you tried out the ls command to list the directory contents, you started a process. A process, in simple terms, is an instance of a running program. The operating system tracks processes through a five-digit ID number known as the pid or the process ID. Each process in the system has a unique pid. Pids eventually repeat because all the possible numbers are used up and the next pid rolls or starts over. At any point of time, no two processes with the same pid exist in the system because it is the pid that Unix uses to track each process. Starting a Process When you start a process (run a command), there are two ways you can run it − Foreground Processes Background Processes Foreground Processes By default, every process that you start runs in the foreground. It gets its input from the keyboard and sends its output to the screen. You can see this happen with the ls command. If you wish to list all the files in your current directory, you can use the following command − $ls ch*.doc This would display all the files, the names of which start with ch and end with .doc − ch01-1.doc ch010.doc ch02.doc ch03-2.doc ch04-1.doc ch040.doc ch05.doc ch06-2.doc ch01-2.doc ch02-1.doc The process runs in the foreground, the output is directed to my screen, and if the ls command wants any input (which it does not), it waits for it from the keyboard. -

How to Restart Premisys Services
PremiSys Services Troubleshooting Introduction There are two services which comprise the PremiSys application server components. These services are: • IDenticard Windows Service • IDenticard Scheduling Service Under normal conditions, both of these services are configured to start automatically when the server starts. Both are also dependent on connection to the PremiSys databases which are hosted by a Microsoft SQL Server. The instance of SQL Server may or may not reside on the same server as the PremiSys application server, depending on the way the system has been designed. IDenticard Windows Service The IDenticard Windows Service is the primary server component of the PremiSys software. It handles the server side code for client logins, licensing, panel communications, transaction processing, etc. When this service is stopped, any running instance of the PremiSys client will receive a message box that indicates “The connection to the {server name} license server has been lost”. When the user acknowledges this message box, the client application will close. If a user attempts to restart the client application while the IDenticard Windows Service is stopped on the Application Server, they will receive a message box which indicates “AddIn Architecture Failed to start – Services unavailable…”. IDenticard Scheduling Service The IDenticard Scheduling Service runs various tasks within a PremiSys system. This includes, but is not limited to user- scheduled tasks for things like backups, transaction archives, reports and door schedules. When this service is stopped, any scheduled tasks will not run on their scheduled execution time. Starting Services Step-By-Step 1.
