Oracle Data replication is a technology that implements a distributed data environment. It creates a distributed data environment by copying data on different physical sites. It is different from distributed databases. In distributed databases, although each data object is available to all sites, a specific data object only exists in a specific site. Data Replication allows all sites to copy the same data object.
In a typical distributed commercial application, you often need to back up data fro

Experiment topology diagram:
Experiments show: The three-tier architecture, R1 and R2 for Headquarters, R3 and R4 for the region, R5 and R6 as branch offices, R7 analog Internet routers
Experiment Request:
1. Branch to the headquarters or other areas to use R1 as the main link, R2 become a standby link
2.IP the hierarchy of address, to be able to achieve routing summary

Three, 3G network management system Construction mode
For different operators, can adopt different network management system construction mode. For new entrants to the mobile operators, mainly to take the new strategy; for the mobile operators who already have 2G networks, because of the construction of 2G network management system, 3G network Management system construction has the following two kinds of options to choose:
Figure 1 Scenario 1-extended to 3G network management system on the
to different systems support;Another factor to consider is the third-party system that accesses EBS, some located at the corporate headquarters, which can be connected directly to the EBS database server, while some are located overseas and do not have the ability to directly connect to the EBS database, in order to achieve this commonality, consider using the webservice approach, That is, publish a public network of webservice, so that it and EBS da

In the 2003, New was invited to Meizhou into the project team, to make the database structure tuning, so that the original overall structural design of the project is still flawed.
In the 2003, Bank of Communications Headquarters in the large data concentration, but also the need for a senior database engineer, to the large database for the overall design, tuning.

Requirements:
Beijing headquarter:
1, the core layer (Core1 and Core2) and the convergence layer (CDS-1,CDS-2,CDS-3 and Cds-4) using the OSPF routing protocol
2, the core layer Core1 and Core2 between the link bundle, convergence layer Cds-1 and Cds-2 do link between the bundle, Cds-3 and Cds-4 do link between the bundle
3, the core layer of Core1 and Core2 do HSRP, to achieve high availability of the network
4, the convergence layer of the switch as a root bridge, and configure load Balanc
The 1,ipsec VPN application is more and more extensive, the following configuration instance is to the single headquarters multiple branch organization actual application
According to the configuration of this article, we can achieve the maximum VPN connectivity through the minimum number of VPN tunnels, the network topology is as follows:
As shown above, the Headquarters firewall machine hub firewall n
Let's see where we're going to use the bidirectional redistribution of routes.
Scene One: The company has 2 technical directors, respectively, management Headquarters and division, the level is similar, director a thinks my side of the router performance is poor, with RIP protocol is enough to use. The head of headquarters thinks that OSPF is better than OSPF. Because of disagreements that led to the divis
Permissions classification
1. System permissions: Permissions for database operations, including but not limited to:CREATE TABLECREATE VIEWCREATE SESSIONCREATE SEQUENCECREATE PROCEDURE......2, object permissions: For user-created tables, view access, modify the ability to manipulate permissions, including but not limited to:SELECTUPDATEINSERTDELETE......
Permission Assignment and Recycling
1. permission assignment:GRANT permissions to user / roleExample 1: assigning access
the VPN configuration, in this way, better remote access is achieved.
Next, we will describe the configuration that can be optimized When configuring VPN for small and medium-sized enterprise users. If the network management can pay attention to these configurations, we believe that the stability of VPN can be effectively improved.
1. Select the appropriate VPN Protocol
Most small and medium-sized enterprise network management systems generally prefer to use simple PPTP, rather than complicated

Lab requirements: The topology is simulated based on the typical C3550-Headquarters-branch structure. The core route of the headquarters is C3550. The Extranet network uses the OSPF protocol and the Intranet is deployed through the VTP protocol to achieve network-wide interconnection.1, the headquarters core switch C3550-1 to create VLAN10/20/30/40, of which VLAN
