You have made the right decision to pursue certification, because being certified in the latest version of Oracle, Oracle Database 12c, will give you a distinct advantage in this highly competitive market. Many readers may already be familiar with Oracle and do not need an introduction to Oracle databases. Oracle databases are the de facto standard for large Internet sites, mission-critical enter- prise applications, and cloud solutions.
With the acquisition of Sun Microsystems, Oracle offers complete enterprise business solutions with engineered systems capable of running world-class databases and applications. Enterprise Resource Planning ERP application suites, data warehouses, and business applications at many large and medium-sized com- panies rely on Oracle. The demand for DBA resources remains higher than others during weak economic times. This book covers two of the exams required for the OCA certification. Why Become Oracle Certified? Oracle certification is the best way to demonstrate your knowledge and skills in Oracle database systems.
Preparing for the certification exam may be the best time spent on your career because you learn the tasks that are necessary to be successful as a DBA. Certification is proof of your knowledge and shows that you have the skills required to support Oracle core products. It demonstrates that you have a solid understanding of your job role and the Oracle products used in that role. The certification tests are scenario-based, which is the most effective way to assess your hands-on expertise and critical problem-solving skills.
OCPs are among the best paid in the IT industry. Salary surveys consistently show the OCP certification to yield higher salaries than the other certifications, including Microsoft, Novell, and Cisco. Introduction xxi So, whether you are beginning a career, changing careers, securing your present posi- tion, or seeking to refine and promote your position, this book is for you! Oracle Certifications Oracle certifications follow a track that is oriented toward a job role. Only the Database track has OCM.
The Database track is clearly for the Database Administrator job role. The best DBAs work behind the scenes, but are in the spotlight when critical issues arise. They plan, create, maintain, and ensure that the database is avail- able for the business, most importantly, DBAs troubleshoot, diagnose, and resolve issues. They have tools to proactively monitor the database for performance issues and to prevent unscheduled downtime.
Sybex has Oracle certification study guides for the Database track. The following sections will introduce you to the different tiers in the Oracle Database 12c certification track. OCA shows that you have the fundamental knowl- edge and skills to support an Oracle Database 12c database. You only need to pass the 1Z The 1Z test is offered at a Pearson Vue facility. The OCP tier challenges you to demonstrate your continuing experience and knowledge of Oracle technologies.
The OCP test will measure your knowledge in setting up and managing multitenant architecture databases and in backup and recovery. The Oracle Database 12c Administrator Certified Professional certification requires you to have the OCA certification as well as to pass the following exam. The OCM certification credential shows that you have the highest level of expertise in an Oracle product. To become a certified master, you must first achieve OCP status and then complete two advanced instructor-led classes at an Oracle Education facility.
You must also pass a hands-on examination at an Oracle Education facility. You may be asked to choose the country of residence before being directed to the site.

The MERGE state- ment performs kind of an upsert—it inserts if the row does not exist, and updates if the row exists.
For more information, read Chapter 6. See Chapter 3 to learn more. Read Chapter 4 to learn more about group functions. See Chapter 6 for more information. For more information, see Chapter 4. The BFILE datatype stores only the locator to an external file in the database; the actual data is stored as an operating sys- tem file. Read Chapter 7 for more information. See Chapter 5 for more information about subqueries. The join condition can be specified by using the ON clause to specify the columns explicitly or using the USING clause to specify columns with common column names.
See Chapter 5 for more information. The index contains all the information needed to satisfy the query in option A, and a full-index scan would be faster than a full-table scan.

Unique constraints allow NULL values in the columns, but primary keys do not.
See Chapter 7 for more information. See Chapter 3 for more information. For more infroma- tion, see Chapter 6. There should be at least n-1 join conditions when joining n tables to avoid a Cartesian join. No other characters are allowed in the table name. You can have letters and numbers in the table name. Since NULLs are sorted higher, they appear at the bottom of the result set in an ascending order sort.

Answers to Assessment Test lvii For databases where the sid is the same as the database unique name, the service name is the same as the sid; thus you can say option C is also part of the easy connect string. However, in reality it is the service name. Easy connect only supports TCP protocol. See Chapter 1 for more information.
In the example, there are two rows with NULL values. Since a self-join is getting data from the same table, you must include alias names and qualify column names. Oracle creates unique indexes for each unique key and primary key defined in the table. Although there is no error in this statement, the statement will not return the desired result. The solid line represents that the order must belong to a customer, and the crow- foot represents that a customer can have more than one order. Private synonyms override public synonyms, and tables or views owned by the user always resolve first.
NOT is a negation operator, and a comma is used to separate column names and table names. For more information, see Chapter 5. You can create primary key, foreign key, and unique key constraints on a view. The constraints on views are not enforced by Oracle. To enforce a constraint, it must be defined on a table. So an AND operator should be used. In the second part, you have two options: the salary can be either more than or less than , so the second part should be enclosed in parentheses; use an OR operator. None of the indexes, constraints, or triggers on the table are dropped or disabled.
OCA/OCP: Oracle9i DBA Fundamentals I Study Guide
If there are valid foreign key constraints defined to this table, you must disable all of them before truncating the table. Read Chapter 6 for more information. Since there can be only one primary key per table, the syntax in option A works. Exam 1Z Installation and Administration 1. Database Upgrade Assistant and a manual upgrade both support an upgrade from For See Chapter 17 for more information. To rename or relocate a data file in Oracle Database 12c, you need to use only the statement specified in option B.
To rename a data file in prec databases, you need to take the tablespace offline so that Oracle does not try to update the data file while you are renaming. To rename the file in the data- base, the new file should exist. Bring the tablespace online for normal database opera- tion. For more information, read Chapter Although pfiles and spfiles are physical files used to configure the Oracle instance, they are not considered part of the database. For more information, see Chapter 8. Answers to Assessment Test lix 4. The highest level at which a user can request a lock is the table level; the only other lock level available to a user is a row-level lock.
Users cannot lock at the block or schema level. Read Chapter 11 for more information. Read Chapter 13 for more information.
Essentials Skills and Certifications Required for Becoming an Oracle DBA Expert
B and C are both the best answers. They are identical because queries in Oracle are case-insensitive. QMN1 is the process that monitors Oracle advanced queuing fea- tures. See Chapter 14 for more information. The resumable session must be enabled using option B. Option C disables the resumable session. Option D is invalid. Read Chapter 10 for more information. The OUI is a Java-based application that provides the same installa- tion look and feel no matter which operating system is being used for the installation. See Chapter 9 for more information. Although you can use choice A to stop and start the listener, doing so temporarily disrupts clients attempting to connect to the database.
Therefore, the best method is C, to use the lsnrctl reload listener1 command to load the new set of values for the listener without disrupting connection service to the databases the listener is servicing. For more information, see Chapter An error will occur because the job is not running, given that a job that is not execut- ing cannot be stopped. See Chapter 16 for more information. Redo log files record all the changes made to the Oracle database, whether the change is committed or not. See Chapter 15 for more information. Default roles are enabled when a user connects to the database, even if the roles are password protected.
Although options A and B are recommended practices for upgrade performance, option D is a must. The Pre-Upgrade Information tool must be run, and all errors must be taken care of before upgrading the database. DBA Related Stuff 1. Views In Oracle.
