Label:As below, create a new two stored procedure: In the master autonomy transaction, we insert a record, then in the autonomous transaction, we look at the number of rows in the table, then try to insert three records, view the number of rows, finally rollback the number of rows, and finally return to the main transaction to see the number of rows. 1, the following code: --Mastertransaction PROCEDURE P_TEST_AT_AND_MT is CNT number:= -1; BEGIN INSERT

increasing cost or using technology to remedy, some IDC providers put forward "dual line", intelligent domain name DNS and CDN scheme respectively. The "dual-line" solution also includes dual-line single-IP routing solutions and dual-line dual-IP solutions. The DNS scheme is based on the domain name of the network resolution (mainly by the Internet users use the DNS server to judge), CDN (Content Delivery Network) solution, that is, "contents publishing and Courier Networks", this is a comprehe

ninth release of the toolbox, represents over fifteen years of development and a substantial level of maturity. this version captures a large number of changes and extensions generated over the last two years which support my new book "robotics, Vision control ". The latest release of the toolbox has been significantly extended to support mobile robots. for ground robots the Toolbox includes standard Path Planning Algorithms (Bug, Distance Transform, D *, PRM), kinodynamics planning (RRT), loc

and calculate the shortest path to each node based on certain algorithms. The Distance Vector-based routing protocol only sends route update information to its neighboring routers. Different from RIP, OSPF divides an autonomous domain into zones. There are two types of routes to be selected: when the source and destination are in the same zone, the intra-zone routes are used; when the source and destination are in different regions, the interval rout

The Border Gateway Protocol, also known as BGP, is mainly used to connect to the routing protocol of independent systems on the Internet, it is an enhanced, comprehensive, and scalable protocol developed by the Internet Engineering Task Group. 1. routes include two basic actions: determining the optimal path and transmitting information groups (usually called groups) over the network. The Network Transmission Group is relatively simple, and the path determination is complex. BGP is a protocol fo

implementations of the former is the "link state routing Algorithm", the latter one of the most typical implementation is "distance vector algorithm".The theoretical principles of both algorithms are not discussed here, and we focus on how the Internet is based on the routing of these two algorithms.First, the entire internet is a very large and complex system, so it is divided into an autonomous system (as) as a whole, running the same routing algor

scope-supports networks of all sizes and supports up to hundreds of routers. ◆ Fast convergence-an update packet is sent immediately after the topology structure of the network changes, so that this change can be synchronized in the autonomous system. ◆ No self-ring --- because OSPF uses the shortest path tree algorithm to calculate routes based on the collected link status, the algorithm itself ensures that no self-loop routing is generated. ◆ Regio

1. Introduction BGP is a routing protocol between autonomous systems. The Network accessibility information exchanged by BGP provides sufficient information to detect the routing circuit and determine the route based on the performance priority and policy constraints. For details, see RFC 1104 [2]. In particular, BGP exchanges the network accessibility information of all AS paths and executes routing policies according to the configuration information

The BGP protocol is designed for routing between autonomous systems, but it can also be used inside autonomous systems and is a type of Dual Routing Protocol. Two BGP adjacent nodes that can communicate between autonomous systems must exist on the same physical link. BGP routers in the same autonomous system can commun
