WAN are divided into the data terminal device (DTE) and the data circuit terminal device (DCE), and the Cisco router acts as the DTE device.
Frame Relay technology provides connection-oriented data link layer communication. Each pair of devices has a defined communication link, and the link has a link identifier. This service is implemented through the Frame Relay virtual circuit, and each frame relay virtual circuit identifies itself with a data link identifier (DLCI. The DLCI value is general

ORACLE sets the process priority in the operating system. We can use the renice command to set the process priority so that the process can obtain the CPU time slice first. In www.2cto.com ORACLE, the parameter _ high_priority_processes can also be used to set the priority of a process. Generally, we may add the LGWR process to this parameter. In my RAC test environment, this parameter adds the LMS process. SQL> SELECT x. ksppinm NAME, y. ksppstvl VAL

processes process) process is primarily used to manage access to data blocks within the cluster and to transmit block mirroring in the Buffer cache for different instances. Copy the data block directly from the cache of the controlled instance, and then send a copy to the requested instance. and ensure that the image of one block of data in the Buffer Cache for all instances can only occur once. The LMS process coordinates the access of the data bloc

Problem description--whatReady to build a lamp environment on a virtual machine's Linux (Centos) system using: sudo yum install httpd; prompts need to be converted to administrator mode.So I switched to root using the sudo command, and I found a hint: LMS is isn't in the sudoers file 2. Cause of the problem--when/why The reason:1.when--When you use sudo to switch root, but not every time you use the command, you will encounter this problem2.w

In addition, C code algorithm is in the frame order of the remote and near-end array xor, the actual application can also be every 1 frames or 2 frames to do XOR, this can expand the search scope.

general, the complexity of the time-delay estimation algorithm of WEBRTC is greatly simplified, especially for the mobile terminal, which is more sensitive to the computation volume. For practical applications, the algorithm also has a space for improvement

Oracle RAC background process Introduction
There are more processes in the Oracle RAC database than in a single instance database. These processes are unique to RAC and are set to implement cluster database functions. This article will introduce RAC-specific processes.
1. LMSn: Global Cache Service Process.
The LMSn Process maintains the data files in the Global Resource Directory (GRD) and the status of each cached block. LMSn is used to transmit messages and data blocks between RAC instances.

The LMS process is the most active background process on RAC, which consumes a lot of CPU. generally, each instance has multiple LMS processes. The default number of LMS processes for each O

The DLCI value is generally specified by the Frame Relay Service Provider. Frame Relay supports both PVC and SVC. The frame relay Local Management Interface (LMS) is an extension of the basic frame relay standard. It is a signaling standard between the router and the frame rela
