Oracle Database Administration II
1Z0-083 Oracle Database Administration II Exam Guide
Oracle 1Z0-083, titled Oracle Database Administration II, validates advanced administration knowledge built on Administration I. Its subject matter includes multitenant databases, backup and recovery, deployment, patching, upgrading, and related operational decisions. This guide is for database administrators pursuing the Oracle Database Certified Professional Administrator 2019 path, as well as eligible upgrade candidates. It helps you decide whether your foundation is ready, which technical areas need hands-on work, how to sequence study, and what to verify before booking preparation or an exam appointment.
What does 1Z0-083 validate?
1Z0-083 tests whether you can apply advanced Oracle Database administration concepts rather than rely only on introductory command recall. Oracle says Administration II assumes knowledge from Administration I and includes multitenancy, backup and recovery, deployment, patching, and upgrading. (https://www.oracle.com/a/ocom/docs/dc/ww-ou-5297-database2019-faq-3.pdf)
The exam’s scope is therefore operational. You should be able to reason about how a database is configured, protected, moved, upgraded, or recovered, and understand the consequences of a chosen administration action. Reading a feature description is useful, but preparation should continually turn that description into a decision: what is the objective, what prerequisites apply, what changes, and how would you verify the result?
Oracle’s study guide also associates the certification with installation, patching, and upgrading of Oracle Database and Oracle Grid Infrastructure for a standalone server. That makes infrastructure awareness part of the preparation picture, not an optional topic reserved for a separate specialist. (https://www.oracle.com/a/ocom/docs/dc/ww-ou-5297-database2019-studyguide-5.pdf)
The main capability groups
The official material points to several connected capability groups: multitenant administration; RMAN backup and recovery; installation and maintenance; deployment and movement; and failure diagnosis. Treat them as connected workflows. For example, a recovery decision depends on the backup strategy, while a multitenant operation can affect security, transport, and recoverability.
What the exam is not
A collection of memorized syntax is not a reliable substitute for administration knowledge. Nor should unofficial question collections or leaked-material claims form the basis of preparation. They cannot establish that you understand the documented behavior of Oracle Database, and memorization does not guarantee a passing result.
Who should take 1Z0-083?
1Z0-083 is intended for candidates who already understand Administration I and now need to demonstrate the advanced administration skills associated with the 2019 DBA certification. New DBAs normally consider it as the second exam after 1Z0-082, while some experienced Oracle professionals may use the upgrade route described by Oracle. (https://www.oracle.com/a/ocom/docs/dc/5110_database_dba_2019_cert-path-guide_final.pdf)
For a new DBA, Oracle’s certification path requires passing both 1Z0-082 and 1Z0-083 for the Oracle Database Certified Professional Administrator 2019 credential. The path guide identifies 1Z0-083 as the second examination, paired with Oracle Database Administration I, 1Z0-082. (https://www.oracle.com/a/ocom/docs/dc/5110_database_dba_2019_cert-path-guide_final.pdf)
Do not interpret “second exam” as a reason to skip foundational study. Administration II assumes knowledge of features covered in Administration I. If you cannot comfortably explain core database architecture, instance and storage relationships, basic security, and routine administration, close those gaps before concentrating on advanced scenarios.
The upgrade candidate decision
Oracle’s path guide says candidates who already hold an OCA on Oracle Database 10g, 11g, 12c, or 12c R2 can take 1Z0-083 as the required examination shown for that upgrade route. Confirm your individual eligibility and the credential outcome with Oracle before scheduling; the path guide is the authority for the route, not a substitute for checking your certification account. (https://www.oracle.com/a/ocom/docs/dc/5110_database_dba_2019_cert-path-guide_final.pdf)
A practical readiness test
You are closer to readiness if you can explain why a particular RMAN strategy fits a recovery objective, distinguish common multitenant administration tasks, outline a safe patch or upgrade approach, and diagnose a failed operation from evidence rather than guesswork. If these tasks require copying steps without understanding their purpose, study the underlying concepts first.
Which skills deserve the most study attention?
Prioritize the domains that require several decisions in sequence: RMAN strategy and recovery, multitenant administration, and installation or maintenance. Oracle’s published material specifically names RMAN strategy, duplication, transportation, failure diagnosis, and multitenant creation, cloning, security, transportation, backup, and recovery. (https://www.oracle.com/a/ocom/docs/dc/ww-ou-5297-database2019-studyguide-5.pdf)
No verified blueprint percentages were supplied in the available research, so this guide does not assign weights to domains. Study time should instead follow your demonstrated weaknesses and the breadth of the official objectives. Treat every domain label as a complete subject area, not as a cue to memorize isolated commands.
Use the following skill map to build a gap list. Mark each item as explain, perform, troubleshoot, or verify. A topic marked only “recognize” is not yet strong enough for scenario-based preparation.
Multitenant administration
Oracle identifies management of container databases, pluggable databases, and application containers as covered skills. The named activities include creation, cloning, security, transportation, backup, and recovery. (https://www.oracle.com/a/ocom/docs/dc/ww-ou-5297-database2019-studyguide-5.pdf)
Study the relationships among the container database, pluggable databases, and application containers before learning individual operations. For every task, record the object being changed, the intended scope, dependencies, security implications, and the checks that confirm success. Practice explaining how a task differs when it concerns the container database rather than a pluggable database.
RMAN backup and recovery
Oracle identifies RMAN backup-and-recovery strategy, database duplication and transportation, and diagnosing failures with RMAN as certification skills. (https://www.oracle.com/a/ocom/docs/dc/ww-ou-5297-database2019-studyguide-5.pdf)
Prepare around objectives rather than command lists. Start with the failure or migration requirement, identify the backup or duplicate operation that addresses it, consider the required state and available files, then define validation. Keep a troubleshooting journal containing the symptom, evidence inspected, likely cause, corrective action, and verification step.
Installation, patching, and upgrading
Oracle’s study guide includes installation, patching, and upgrading of Oracle Database and Oracle Grid Infrastructure for a standalone server. (https://www.oracle.com/a/ocom/docs/dc/ww-ou-5297-database2019-studyguide-5.pdf)
Study maintenance as a controlled change process. Map prerequisites, inventory the current environment, identify the affected components, plan rollback or recovery considerations, and establish post-change checks. Do not reduce patching and upgrading to a sequence of commands; the important preparation question is why each stage exists and what evidence shows that the environment is healthy afterward.
Deployment and movement
The certification FAQ includes deployment among the advanced topics, while the study guide names RMAN database duplication and transportation. (https://www.oracle.com/a/ocom/docs/dc/ww-ou-5297-database2019-faq-3.pdf)
Separate copying a database from making it usable in its target environment. Your notes should cover source and destination assumptions, naming and configuration differences, security, compatibility, recovery implications, and validation. This distinction helps prevent a common mistake: treating a technically completed transfer as an operationally complete deployment.
How should you use Oracle’s official learning material?
Use the official study guide as the scope reference, then use Oracle training and documentation to turn each objective into an explanation and a repeatable task. Oracle lists Backup and Recovery Workshop, Multitenant Architecture, and Oracle Database New Features among recommended training associated with 1Z0-083. (https://www.oracle.com/a/ocom/docs/dc/5110_database_dba_2019_cert-path-guide_final.pdf)
The Oracle learning environment organizes content through learning paths, courses, and modules, and provides search and filters for available learning. Oracle also provides an official preparation course for 1Z0-083 that uses sample questions and a practice exam with pointers to useful resources. (https://learn.oracle.com/ols/home/79684)
Do not begin by opening every available course. Start by translating the official skill areas into a study checklist. Then select the learning item that addresses the weakest capability, complete it actively, and record what you can now explain or perform. This approach reduces passive viewing and makes progress visible.
A useful source hierarchy
Use the certification FAQ and path guide to understand purpose, pathway, and recommended training. Use the study guide to define technical coverage. Use Oracle’s learning paths for structured instruction. Use product documentation when you need exact behavior, prerequisites, restrictions, or recovery detail. This hierarchy keeps preparation anchored to authoritative material.
The RMAN documentation workflow
Oracle provides the Oracle Database Backup and Recovery User’s Guide for 19c. (https://docs.oracle.com/en/database/oracle/oracle-database/19/bradv/index.html) Read it selectively: begin with the section related to your objective, extract the decision rules and prerequisites, then test your understanding in a controlled environment. Documentation is most valuable when you use it to answer a specific administration question rather than read without a task.
Notes that support revision
For each feature, write five items: purpose, prerequisites, principal choices, failure symptoms, and validation. Add a short comparison only when two choices are easy to confuse. Avoid copying long command examples into your notes unless you also explain what the command changes and how you would confirm the outcome.
What is the best hands-on preparation method?
Build small, repeatable scenarios instead of attempting an unstructured database project. Each scenario should have a stated objective, a starting state, an administration action, an intentional verification step, and a recovery or troubleshooting question. This method develops the judgment needed for multitenant, RMAN, deployment, and maintenance topics without implying access to live exam questions.
Scenario one: recovery planning
Begin with a recovery objective and document what information you need before acting. Identify the relevant backup pieces or configuration information, determine the intended recovery result, perform the operation in your practice environment, and verify the database afterward. Then deliberately introduce a failure in the procedure or environment and write down how you would isolate it.
Scenario two: duplication or transportation
Plan a database movement exercise from source assumptions to target validation. List identity, storage, connectivity, security, and recoverability considerations before executing anything. Afterward, verify more than the presence of files: check whether the target database behaves as intended and whether the resulting configuration matches the stated deployment goal.
Scenario three: multitenant operations
Create a checklist for a container database, a pluggable database, and an application container. For each, identify the scope of the action and the privileges required. Practice creation or cloning concepts, security implications, movement, and backup or recovery considerations. Explain what would be different if the task were performed at another container level.
Scenario four: maintenance change
Use a change record for installation, patching, or upgrading. Capture the starting version and configuration, prerequisites, planned sequence, safeguards, and post-change tests. The exercise is complete only when you can state what would make you stop, roll back, or investigate rather than continue automatically.
How can you turn the objectives into a study plan?
A reliable plan moves from scope, to foundation, to guided practice, to mixed scenarios, and finally to decision-focused review. Do not assign equal study effort automatically. Use an initial diagnostic to identify whether your weakness is conceptual knowledge, execution, troubleshooting, or verification, then choose the next activity accordingly.
Phase one: establish scope
Collect the official FAQ, path guide, and study guide. Write the named domains on one page and divide each into smaller tasks. Confirm whether you are following the new-DBA path or an upgrade route. At this stage, do not estimate readiness from familiarity with course titles; identify tasks you can actually explain.
Phase two: repair Administration I gaps
Because Oracle says Administration II assumes Administration I knowledge, revisit any foundational subject that blocks an advanced task. A multitenant recovery exercise is not a good test of advanced understanding if basic database states, storage relationships, or security boundaries remain unclear. Repair the smallest prerequisite gap, then return to the advanced scenario. (https://www.oracle.com/a/ocom/docs/dc/ww-ou-5297-database2019-faq-3.pdf)
Phase three: study by operational thread
Run one thread through the relevant domains: protect a database, move or duplicate it, maintain it, and diagnose a failure. This reveals dependencies that topic-by-topic reading can hide. Keep separate notes for facts, procedures, assumptions, and troubleshooting evidence so that revision does not blur them together.
Phase four: use practice questions diagnostically
Oracle’s official preparation material includes sample questions and a practice exam with pointers to useful resources. Use questions to locate reasoning gaps, not to memorize answer patterns. After each missed item, explain why the chosen option fails, what evidence would change the decision, and which Oracle source resolves the uncertainty. (https://learn.oracle.com/ols/home/79684)
Phase five: final consolidation
Build a short review sheet from your own errors. Include confusing terms, prerequisite conditions, recovery decisions, multitenant scope distinctions, and maintenance validation checks. Retest yourself by explaining the choices aloud or writing a procedure from the objective, then consult the documentation to correct imprecise statements.
What mistakes commonly weaken preparation?
The most damaging mistakes are treating Administration II as an isolated exam, studying commands without objectives, ignoring failure diagnosis, and confusing a practice threshold with the certification requirement. Correct these by tying every study activity to an official skill, a practical scenario, and a verification method.
Skipping the foundation
Candidates sometimes move directly to advanced features because the exam title sounds specialized. Oracle explicitly says Administration II assumes Administration I knowledge. Use the prerequisite relationship to guide your diagnostic: if a basic concept prevents you from understanding an advanced scenario, resolve it before adding more advanced notes. (https://www.oracle.com/a/ocom/docs/dc/ww-ou-5297-database2019-faq-3.pdf)
Memorizing RMAN recipes
A remembered sequence can fail when the objective, database state, or available backup information changes. Study the recovery goal, required conditions, expected output, and diagnostic path together. Oracle specifically includes diagnosing RMAN failures, so your practice should include investigating why an operation did not work, not only repeating a successful example. (https://www.oracle.com/a/ocom/docs/dc/ww-ou-5297-database2019-studyguide-5.pdf)
Flattening multitenant scope
Using “the database” as a vague label can conceal whether an action concerns the container database, a pluggable database, or an application container. Put the object and scope in every note. Add security, transportation, and recovery consequences so that your understanding reflects the full skill rather than a single creation command.
Treating practice results as proof
Oracle’s official 1Z0-083 practice exam states that an 80% or higher score is required to pass that practice exam. That threshold belongs to the practice exam and should not be presented as the certification examination’s passing requirement. Use the result as one diagnostic signal, then review the reasoning behind every uncertain answer. (https://learn.oracle.com/ols/module/practice-exam-1z0-083/42305/79942)
Relying on stale material
Oracle learning pages and course environments can change. Check the current official learning page, certification information, and documentation before final revision. If a third-party explanation conflicts with Oracle’s current source, do not quietly merge the two; identify the conflict and resolve it using the authoritative material.
What delivery details are officially evidenced?
Oracle’s learning path lists 1Z0-083 as an online certification exam with a two-hour duration. That is the supported delivery information in the supplied research. Verify current registration, appointment, system, identification, language, and policy details through Oracle before scheduling because those items are not established by the available facts here. (https://learn.oracle.com/ols/learning-path/oracle-database-administration-ii/63634/63635)
Do not confuse the Oracle learning page for the certification exam with the separate practice-exam page, which contains instructions for scheduling and accessing a lab environment. Lab instructions are useful for hands-on training, but they do not establish the delivery conditions of the certification examination.
Preparing your technical setup for learning
The supplied practice-lab page includes system guidance such as an unshared internet connection, headphones with a microphone, supported browser information, and a connectivity test. Treat these as requirements or recommendations for that Oracle learning activity, not automatically as certification-exam rules. Test the relevant Oracle environment before a scheduled lab and use Oracle Support instructions for lab issues. (https://learn.oracle.com/ols/module/practice-exam-1z0-083/42305/79942)
Scheduling a practice lab
The practice-lab instructions state that a lab must be scheduled to obtain lab time and advise checking back 12 hours before the lab starts for access credentials. These directions apply to the referenced lab activity. They do not replace the certification appointment process, so follow the current Oracle certification registration workflow for the actual exam. (https://learn.oracle.com/ols/module/practice-exam-1z0-083/42305/79942)
What to verify before booking
Confirm the exact exam title and code, your pathway or upgrade eligibility, the current appointment options, and the rules shown in Oracle’s current registration flow. The supplied research does not verify a price, question count, passing score for the certification exam, languages, prerequisites beyond the stated pathway context, or retirement status, so do not rely on unofficial figures for those decisions.
How should you use a practice environment?
Use a lab to test reasoning, not to chase a list of commands. Before each session, write the objective and expected evidence; during the session, capture the state and errors; afterward, explain what happened and how you would confirm or repair it. A lab becomes preparation only when you connect the action to the administration decision.
A repeatable lab record
Record the starting configuration, the task, assumptions, commands or interface actions, observed result, verification query or check, and any cleanup. Add a “what if it fails?” line. This record becomes a revision asset and helps distinguish a genuine understanding from a successful action caused by an unexamined starting state.
When a lab is unavailable
Do not postpone all study because an Oracle lab slot is unavailable. Use the official documentation to diagram the workflow, review prerequisites, trace expected states, and write a troubleshooting decision tree. Return to hands-on testing when an environment is available and use the exercise to validate the parts you previously inferred.
Protecting lab credentials
Oracle’s practice-lab instructions warn candidates not to share lab credentials in community posts. Keep access details private, use the support path for technical issues, and do not publish environment information in study notes that may be shared. (https://learn.oracle.com/ols/module/practice-exam-1z0-083/42305/79942)
What should you do in the final review?
Replace broad rereading with targeted retrieval. Take each official skill area and answer four questions: what problem does it solve, what conditions must be true, what can go wrong, and how do I verify the outcome? Finish by checking current Oracle information and ensuring your appointment decision matches your actual readiness, not a hoped-for score.
The final technical checklist
Review multitenant object scope, creation and cloning decisions, security boundaries, transportation, and backup or recovery implications. Review RMAN strategy, duplication, transportation, recovery objectives, and failure diagnosis. Review installation, patching, upgrading, deployment, and post-change validation. Link each item to an Oracle source or to a documented lab result.
The final confidence check
Use mixed scenarios rather than another isolated topic drill. When you choose an action, state the objective and the evidence supporting it. When you reject an alternative, state the condition that makes it unsuitable. This is a stronger readiness signal than recognizing familiar terminology.
The booking decision
Schedule when you can work through the official scope with stable reasoning and have resolved the prerequisite gaps identified by your diagnostic. If your knowledge is limited to notes or practice-answer recall, continue with documentation and hands-on scenarios. Before committing, recheck Oracle’s current exam page and pathway information for details not verified in this guide.
Where can you continue after this guide?
Start with Oracle’s Administration II learning path and certification path guide, use the official FAQ and study guide to confirm scope, and consult the 19c Backup and Recovery User’s Guide for detailed RMAN work. These sources support a preparation process based on documented objectives, practical decisions, and evidence rather than unsupported exam claims.
Recommended next actions
First, confirm whether you are following the new-DBA route requiring 1Z0-082 and 1Z0-083 or an eligible upgrade route. Second, create the skill gap list. Third, study the weakest domain using Oracle material. Fourth, complete a lab or written scenario that includes verification and failure diagnosis. Finally, use the official practice exam diagnostically and recheck current scheduling information before booking.
The central preparation principle
Prepare to administer and explain the technology represented by the objectives. If you can connect a requirement to a configuration choice, a recovery or deployment action, a failure symptom, and a verification step, your study is addressing the real work behind the certification rather than merely rehearsing its vocabulary.
Conclusion
1Z0-083 is best approached as an advanced administration assessment built on Administration I. Its official scope emphasizes multitenant management, RMAN strategy and troubleshooting, deployment, installation, patching, and upgrading. Use Oracle’s path and study materials to define coverage, use documentation to resolve technical detail, and use labs and practice questions to expose reasoning gaps. Then verify the current Oracle registration information and your pathway before scheduling. That sequence gives you a practical basis for deciding whether to book now or strengthen a specific skill first.
