how to protect your sensitive data using oracle database vaultAnar Godjaev
- Oracle Database Vault provides powerful security controls to help protect sensitive application data from unauthorized access and comply with privacy regulations. It controls privileged account access and sensitive operations inside the database using multi-factor authorization.
- Database Vault realms prevent privileged accounts from accessing application schemas, sensitive tables, and stored procedures. It also controls database configuration changes and prevents unauthorized changes to database entitlements.
- Database Vault is configured easily and runs transparently with minimal performance impact. It implements duty separation, restricting even DBA users' access and controling database operations. Once enabled, it provides strong protection of applications and data.
Jdbc Best Practices - Oracle/IOUG, Toronto, April 21, 2004derek_clark_ashmore
The document summarizes best practices for using JDBC to access Oracle databases. It discusses closing JDBC objects in finally blocks, turning off auto-commit for selects, auditing platform-specific features, specifying column lists, using statement batching and fetch sizing, referencing only java.sql classes, utilizing connection pooling, and separating database access code from business logic. The document is presented by Derek C. Ashmore and covers his experience and an agenda for discussing additional JDBC best practices.

Oracle RAC - Standard Edition, Enterprise Edition & One NodeLeighton Nelson
This document discusses different options for choosing between Oracle Real Application Clusters (RAC), Standard Edition (SE), and RAC One Node. It provides an overview of Oracle Clusterware and RAC architectures. Standard Edition RAC supports up to 4 sockets and requires ASM, while Enterprise Edition has more scalability and supports third-party clusterware. RAC One Node provides high availability with one database instance and supports server consolidation. The document compares features and considerations for each edition and provides examples of suitable scenarios.

15.Which two statements about multitenant architecture are true?
A. Multiple PDBs on a single server need multiple database instances and multiple sets of database files.
B. Although consolidated into a single physical database, PDBs mimic the behavior of non-CDBs.
