The Linux release version is Ubuntu server 6.06, And the Ubuntu version is only 8.1. To be an early adopter, 8.2.0 has improved the compatibility based on the Windows platform to facilitate the conversion of the platform. At the same time, you can customize some parameters and settings for source code installation. Although Ubuntu has good usability and compatibility, and some features are newer, it is somewhat similar to Windows, the reduction also closes a lot of details, so developers do not

PostgreSQL is an object-relational database (database management system) based on the BSD license. Because of the flexibility of the license, anyone can use, modify, and distribute PostgreSQL for free for any purpose. Simply put, even if you take it to change it, and then take it out and sell it, no one will be in control. Therefore, a lot of domestic database is based on

When a process exits due to an error, the monitoring process receives a message indicating that the process exits. With these features, using Erlang to build a simple and robust sys

Now, when talking about free databases, most people may first think of MySQL. Indeed, MySQL has been applied in many domestic fields, especially in website setup. However, PostgreSQL is actually the most powerful, rich, and complex free database. Many of its features are the predecessor of many commercial databases such as Oracle and DB2. As a matter of fact, I recently came into contact with PostgreSQL bec

Now talk about the free database, most people think first of all may be MySQL, indeed MySQL has been used in many areas of the country, especially the site erection. But, in fact, the most powerful, most feature-rich and complex free database should be PostgreSQL. Many of its features are the predecessor of today's many business databases, such as Oracle, DB2, and so on. In fact, the author is also recently because of the needs of the project, contact

The PostgreSQL database is a high-performance, full-featured, open-source relational database that explains how to install PostgreSQL 10 under Ubuntu 16.04 LTS.

Comparison between monitoring treasure and zenoss, zenoss monitoring After graduation, I came to my current company and started O M. When we first arrived, our project had only 10 servers, single point mysql server and web server. After nearly three years, the project now has three DataCenter and more than one hundred servers, mysql Sync and more than a dozen web servers between the three DC servers.

In this scenario, I constructed a useful example without creating an index on the Sales_order table. As a result, monitoring will reveal more sequential scans (in database terms for table scans), which is a inefficient mechanism for retrieving data because it reads each row in the table. Sequential tuple reads-the number of rows that are read using sequential scans. There is a big difference between rows and tuples, but it doesn't matter here. To unde

From accidentally climbing the blog PostgreSQL is a powerful open-source relational database system. after more than 15 years of development, it has won an excellent reputation in terms of reliability, data integrity, and correctness. it runs on all major operating systems, including Linux, UNIX (AIX, BSD, HP-UX, sgi irix, Mac OS X, Solaris, Tru64) and Windows. it fully complies with ACID principles and fully supports foreign keys, joins, views, trigg

This article mainly introduces the DB2 database development and PostgreSQL development in the actual operation of some of the similarities, and the difference, recently used DB2, wrote a point of difference. Not necessarily exactly right. But you can look at the difference. 1, Data Definition language (DDL) and peripheral tools: the difference between DB2 and PostgreSQL is almost 0, the specific difference
