requirements, in order to give full play to the design efficiency, to achieve the best operating results, the computer hardware and software systems need to carry out a more complete performance testing and optimal configuration, especially the good or bad memory configuration of the system running speed has a decisive role Next, I put forward some understanding and views on how to optimize the memory configuration of SQL Server database servers.

One of the Sybase replication server application Scenarios
Replication servers support one-to-one replication mode, and the replication server's warm standby maintains a dual database for adaptive server or SQL Server, one of which is a warm backup of another active database. When a user modifies an active database, the replication server replicates the corresponding transaction to the backup database, making the two consistent. One but the active da
The request processing engine is equivalent on both servers.
The programming interface application communicates with the database server using a programming interface. You can use ODBC, JDBC, OLE DB, Sybase Open Client, or Embedded SQL.
Many application development tools provide your own programming environment, which hides the details of the underlying interface. For example, if you use Sybase PowerBuilder to develop an application,
You never have
. For these two types of backup patterns, you can divide your Exchange server's data protection tasks into three areas:
Application Protection
This protection includes backup and recovery of application files for Exchange servers, cluster support, and disaster recovery steps to restore the entire application system. At the level of application protection, our focus is on backing up the application files and configuration of the Exchange server. Beca

The last article just completed the automatic installation of Nagios, this article continues, think of the previous days manually configured kickstart server process is more cumbersome, the idea is not clear, or the installation configuration process to write into the script is very convenient, feeling is once and for all, reduce the follow-up work of the Labor, And the whole idea process is clearer.

availability of the implementation of the Cluster service (also known as resources). It can do clusters of almost any size, and comes with a powerful dependency pattern that allows administrators to accurately express the relationships between cluster resources (including order and location). Almost any script that can be written can be used as part of managing a pacemaker cluster.
Test Purpose:
Implementing Corosync+pacemaker for high availability management of

Features include: Restricting access to some users based on a Web server or list of URLs, blocking access to Web servers and URLs on the blacklist, blocking access to URLs that are matched by certain users to regular expressions, and enforcing domain access in URL paths that prohibit IP access; Redirect blocked URLs to a

Setting up an FTP server has always put security first, especially with FTP servers built with tools like IIS. If the improper setting suffers a malicious attack, the entire server system crash is not alarmist! Therefore, it is necessary to take reasonable and comprehensive safety management.
Let's start with the security of IIS.
IIS, starting with the NT system kernel, has become an important information release carrier, but its unavoidable vulnera
