Transcription de la présentation

  1. Networking Overview

  2. Objectives • After completing this lesson, you should be able to do the following: • Explain the solutions in Oracle9i that can be used to manage complex networks • Describe Oracle networking add-on solutions

  3. Network Environment Challenges • Configuring the network environment • Maintaining the network • Tuning, troubleshooting, and monitoring the network • Implementing security in the network • Integrating legacy systems

  4. Simple Network: Two-Tier • Network connects client and server • Client and server speak the same language or protocol Network Client Server

  5. Simple to Complex Network: N-Tier • Client can be a thin client or a PC • Middle tier can contain applications and services • Server holds actual data Network Network Client Middle tier Server

  6. Complex Network TCP/IP SSL TCP/IP SSL TCP/IP TCP/IP Named Pipes TCP/IP

  7. Oracle9i Networking Solutions • Connectivity • Directory Services • Scalability • Security • Accessibility

  8. Connectivity: Key Features ofOracle Net Services • Protocol independence • Comprehensive platform support • Integrated GUI administration tools • Multiple configuration options • Tracing and diagnostic toolset • Basic security

  9. Any platform Any platform Connectivity: Oracle Net Services Administration and configuration Oracle Net Oracle Net Protocol Protocol Client Server

  10. Connectivity: Database Connectivity with HTTP Web browser HTTP Oracle9i

  11. Directory Services: Directory Naming • Process of resolving a network alias using an LDAP-compliant directory server • Clients must be configured to use the LDAP compliant server

  12. Directory Services: OracleInternet Directory • Oracle’s LDAP compliant directory service • Provides the following features: • Integrates tightly with Oracle9i • Simplifies network administration • Provides a secure and reliable directory structure

  13. Scalability: Oracle Shared Server • Enables a large number of users to connect to a database simultaneously • Database resources are shared resulting in efficient memory and processing usage • Connections are routed via a dispatcher • Server processes are not dedicated to each client • Server processes serve client processes as needed

  14. Scalability: Oracle Connection Manager • Oracle Connection Manager offers: • Multiplexing of connections • Cross-protocol connectivity • Network access control

  15. Scalability: Oracle Connection Manager 2 1 3 Oracle ConnectionManager Server

  16. Security: Advanced Security • Encryption • Encodes between network nodes • DES, RSA, 3DES • Authentication • Authenticates users through third-party services and Secure Sockets Layer (SSL) • Kerberos, Radius, CyberSafe • Data Integrity • Ensures data integrity during transmission • MD5, SHA

  17. Advanced Security Encryption Corporate earnings are up 45% this quarter Corporate earnings are up 45% this quarter 1 3 Oracle Advanced Security Installed Oracle Advanced Security Installed Decrypt Server Client 2 Encrypt fdh37djf246gs’b[da,\ssk

  18. Security: Oracle Net Services and Firewalls • Oracle works with key firewall vendors to provide firewall support • Oracle Net Firewall Proxy Kit allows firewall vendors to provide connection support for Oracle environments • Oracle Net Firewall Proxy is based on Oracle Connection Manager • Oracle supports two categories of firewalls: • Proxy-based firewalls • Stateful packet inspection firewalls

  19. Accessibility: Heterogeneous Services • Enables access of legacy data as if it resides in a single, local relational database • Enables Oracle procedure calls to access non-Oracle systems, services, or APIs

  20. Accessibility: External Procedures • Functions written in a 3GL language that can be called from PL/SQL • Allows the developer more flexibility than SQL or PL/SQL provide • Listener can listen for external procedure calls • Connections to external procedure can be configured during or after server installation

  21. Oracle Net Services Configuration and Administration Tools • Oracle Net Manager • Used for configuring and managing Oracle Net • Client- or server-based tool • Integrated with Oracle Enterprise Manager • Oracle Net Configuration Assistant • Oracle Net Control utilities • Listener Control utility • Oracle Connection Manager Control utility • Oracle Names Control utility

  22. Oracle Net Manager

  23. Oracle Net Configuration Assistant

  24. Summary • In this lesson, you should have learned how to: • Explain Oracle’s solutions for managing complex networks: • Oracle Net Services • HTTP Connectivity • Oracle Internet Directory • Oracle Shared Server • Connection Manager • Describe Oracle’s add-on solutions: • Oracle Advanced Security • Heterogeneous Services
