feature that ensures that organizations can take advantage of XML functionality in a native way. With the DB2 express-c 9 PureXML feature, you no longer need to store documents in large objects (lobs) or to break them into objects. Although IBM DB2 Express-c is well-suited to the needs of small and midsize enterprises, it does not provide all the features available in later versions. DB2 Express-c does not contain the following features in other DB2 9 versions:

I. Overview
As its name implies, Hub is the activity center. In network terms, the Hub or Concentrator is a wiring point based on a star topology. Arcnet, 10Base-T, 10Base-F, and many other dedicated networks rely on hubs to connect each segment of cables and distribute data to each segment. The basic function of a hub is information distribution, which distributes all signals received by a port to all ports. Some hubs regenerate weak signals before

In many cases, applications with asymmetric encryption are not limited to servers, but also need to be used on network devices, such as SSH, the certificate is the most typical application of asymmetric encryption. It is particularly famous for its IPsec-based VPN applications, such: certificates can be used when configuring VPN based on Cisco IOS, ASA, PIX, and VPN concentrator
L2TP, l2f does not have a definite customer. Note that l2f is only valid in the forced tunnel. (For more information about voluntary and forced tunnels, see "Tunnel Type ").
Layer-3 Tunneling Protocol (L2TP)The L2TP tunnel protocol is a typical passive tunnel protocol. It combines the advantages of l2f and PPTP to allow users to initiate VPN connections from the client or the access server. L2TP is an encapsulation protocol that encapsulates the link layer PPP frames in public network facilitie
