The LGWR writes the redo log buffers to the on-line redo log files. LGWR (LoG WRiter) is an Oracle background process created when you start a database instance. It is a database commonly used for running online transaction processing (OLTP), data warehousing (DW) and mixed (OLTP & DW) database workloads. Oracle Database (commonly referred to as Oracle RDBMS or simply as Oracle) is a proprietary multi-model database management system produced and marketed by Oracle Corporation. The kernel process does not have a root directory or a current directory when initialized. Because kernel processes are always in the kernel protection domain, threads within a kernel process are kernel-only threads. Whenever a command is issued in unix/linux, it creates/starts a new process.ДЄ kernel process controls directly the kernel threads. This instance consists of all the services/resources that may be utilized by the process under execution. A program/command when executed, a special instance is provided by the system to the process. A process is an executing instance of a program. User space is that set of memory locations in which user processes (i.e., everything other than the kernel) run. Kernel space is where the kernel (i.e., the core of the operating system) executes (i.e., runs) and provides its services. What is difference between kernel space and user space? But still you can send signals to your Daemon. So when you close your terminal it will not be killed by OS. And that is why a Daemon is not connected to a terminal. The key difference between a Process and a Daemon is that a DaemonвЂ™s parent is init вЂ“ the first process started during *Nix booting. What is the difference between user process and daemon processes? The process/kernel model assumes that processes that require a kernel service use specific programming constructs called system calls.

The kernel itself is not a process but a process manager. Server programs generally receive requests from client programs, execute database retrieval and updates, manage data integrity and dispatch responses to client requests. There are five types of kernels: A micro kernel, which only contains basic functionality A monolithic kernel, which contains many device drivers.ДЄ server process (program) fulfills the client request by performing the task requested. It manages the operations of the computer and the hardware, most notably memory and CPU time. The related file name is C:WindowsSystem32 toskrnl.exe.ДЄ Kernel is the central part of an operating system.

It is the host of all kind of drivers (network, disk, USB). This system process is a single thread running on each processor. The system process is responsible for the system memory and compressed memory in the NT kernel. Every database access of the Oracle Client is done through the shadow process. The listener will create a so called Shadow process which then will connect to the Oracle Client program. Oracle clients (that are programs using the oracle database) will not directly access the database files. On Windows, an Oracle background process is a thread of execution within a process. For example, on Linux an Oracle background process is a Linux process. The mechanism depends on the operating system.
