Oracle Database Administration II
1Z0-083 Oracle Database Administration II Exam Guide
Oracle 1Z0-083, titled Oracle Database Administration II, validates advanced administration knowledge for Oracle Database 2019 certification candidates. It is intended especially for administrators progressing from Administration I, while experienced Oracle DBAs may use it as the required exam in an upgrade route described by Oracle. The central decision is whether to study 1Z0-083 as a theory test or as an operational administration exam: the official scope points toward multitenant management, RMAN, deployment, patching, and upgrading. This guide helps you map that scope, choose a sensible study order, and decide when your preparation is sufficiently practical.
What does 1Z0-083 certify?
1Z0-083 is Oracle Database Administration II, the advanced companion to Oracle Database Administration I. Oracle’s 2019 Database Certified Professional path identifies it as the second exam, paired with 1Z0-082. For a new DBA, passing both exams is required for the Oracle Database Certified Professional Administrator 2019 credential.
The exam therefore should not be approached as an isolated collection of database commands. Oracle’s certification FAQ says Administration II assumes knowledge of features covered in Administration I and tests advanced topics such as multitenancy, backup and recovery, deployment, patching, and upgrading. Your preparation should reinforce Administration I foundations whenever an advanced topic depends on them.
The credential path matters when planning your attempt. If you are new to the DBA certification route, confirm that 1Z0-082 is also part of your plan. Oracle’s path guide separately identifies 1Z0-083 as the required exam shown for an upgrade route for candidates who already hold an OCA on Oracle Database 10g, 11g, 12c, or 12c R2. Those are different planning situations, so check the applicable Oracle path before scheduling.
Who should take this exam?
1Z0-083 is best suited to an Oracle administrator who already understands core database administration and is ready to reason about recovery, multitenant environments, and lifecycle operations. It is not a sensible starting point if basic administration concepts from Administration I are still unfamiliar.
New DBAs should use 1Z0-082 as the foundation and treat 1Z0-083 as the second stage of the 2019 professional path. Experienced administrators should compare their existing Oracle version knowledge with the Administration II scope rather than assuming that years of general database experience cover Oracle-specific operations.
The practical audience includes candidates who need to make controlled decisions: how to structure container and pluggable databases, how to choose and validate an RMAN approach, how to diagnose a failed recovery operation, and how installation, patching, or upgrading affects a standalone server. These are preparation targets derived from Oracle’s published skill descriptions, not a claim that every production environment uses the same design.
Use the upgrade route only when it applies
Oracle’s path guide identifies an upgrade route for candidates holding an OCA on Oracle Database 10g, 11g, 12c, or 12c R2. If that description matches you, verify the current certification path and registration instructions before treating 1Z0-083 as your only required step. If it does not match you, do not infer that the upgrade route replaces the paired-exam path.
Which skills does Oracle measure?
Oracle’s official study guide groups the exam’s practical emphasis around advanced database administration. The documented areas include installation, patching, and upgrading Oracle Database and Oracle Grid Infrastructure for a standalone server; RMAN strategy, duplication, transportation, and failure diagnosis; and management of multitenant container, pluggable, and application containers.
The official FAQ gives the same broad direction in shorter form: multitenancy, backup and recovery, deployment, patching, and upgrading. Use those themes as your scope boundary. They are more useful than collecting unrelated database topics simply because they appear in general Oracle documentation.
No blueprint percentages are supplied in the approved research for this guide. Consequently, there is no evidence-based basis for assigning study time by percentage or comparing domain weights. Allocate time according to your baseline, the complexity of each task, and the results of practice—not according to invented weighting figures.
Multitenant administration
Oracle specifically identifies management of container databases, pluggable databases, and application containers. The listed activities include creation, cloning, security, transportation, and backup and recovery. Study these as connected administration decisions rather than separate vocabulary items.
A useful exercise is to describe the object being managed, the operation being performed, the dependencies involved, and the recovery or security consequence. For example, when reviewing a cloning or transportation procedure, ask what must be prepared, what state must be preserved, and how the resulting database fits into the container architecture.
RMAN and recovery operations
Oracle identifies RMAN backup-and-recovery strategy, database duplication and transportation, and diagnosing failures with RMAN as covered skills. Your preparation should therefore go beyond remembering command syntax. You need to understand why a strategy is selected, what outcome it is intended to produce, and how you would investigate an unsuccessful operation.
The Oracle Database Backup and Recovery User’s Guide, 19c is an appropriate reference for structured reading. Use it to trace a complete workflow: define the recovery objective, identify the relevant backup or recovery mechanism, perform the operation in a controlled environment, and investigate the evidence when the result is not as expected.
Deployment, patching, and upgrading
Oracle describes preparation as covering installation, patching, and upgrading of Oracle Database and Oracle Grid Infrastructure for a standalone server. Treat these as lifecycle tasks with prerequisites, sequencing, and rollback or recovery implications rather than as one-time installation knowledge.
When studying a procedure, write down the starting state, the change being introduced, the validation step, and the action you would take if validation failed. This habit helps connect deployment knowledge to the troubleshooting emphasis in the exam scope.
What should you study first?
Start with the Administration II learning path and official study guide, then use the relevant Oracle training and documentation to close identified gaps. A sound sequence is foundations, multitenant architecture, RMAN strategy, recovery diagnosis, duplication and transportation, and finally lifecycle operations such as patching and upgrading.
Oracle lists Backup and Recovery Workshop, Multitenant Architecture, and Oracle Database New Features among recommended training associated with 1Z0-083. These recommendations suggest a useful order, but they do not remove the need to check what you can actually perform and explain. Begin with a baseline assessment so that familiar subjects do not consume the time needed for weak areas.
The Oracle Learn page also provides an official preparation course for 1Z0-083 that uses sample questions and a practice exam with pointers to useful resources. Use those materials to identify misunderstanding and review targets. Do not treat practice questions as a substitute for learning the underlying administration decisions.
Build a scope matrix
Create a simple matrix with one row for each official theme and four columns: explain, configure, validate, and troubleshoot. Mark a topic as ready only when you can do more than define it. This is a practical recommendation, not an Oracle scoring rule.
For multitenant work, record whether you can explain the role of each container type and reason through creation, cloning, security, transportation, and backup or recovery. For RMAN, record whether you can describe strategy, duplication, transportation, and failure diagnosis. For patching and upgrading, record whether you can explain the lifecycle sequence for the standalone-server context named by Oracle.
Close the Administration I gaps
Because Oracle says Administration II assumes Administration I knowledge, pause advanced study when a question exposes a basic gap. Review the relevant Administration I concept, then return to the advanced scenario and explain the dependency in your own words.
This prevents a common mistake: memorizing an advanced procedure without understanding the database state it changes. A candidate who cannot describe the starting configuration will struggle to choose a valid next step when a scenario changes one condition.
How should you practise RMAN?
Practise RMAN as a decision-and-diagnosis cycle: define the recovery requirement, select an approach, execute it, verify the result, and investigate failure evidence. This mirrors Oracle’s stated emphasis on strategy and diagnosing failures rather than reducing preparation to command recall.
Use the official 19c Backup and Recovery User’s Guide as your reference while building controlled exercises. Keep a record of the initial state, the command or procedure used, the expected result, the observed result, and the explanation for any difference. The record becomes a troubleshooting notebook for later revision.
Include separate exercises for backup and recovery strategy, database duplication, and transportation. Oracle names each of these areas. Do not assume that success in one proves competence in the others; they test different decisions and failure modes.
A practical RMAN exercise pattern
Begin by writing the objective without using a command. Next, list the database state and resources the operation depends on. Perform the procedure in a safe lab, then validate the result using appropriate evidence. Finally, deliberately review what could cause failure and where you would look first.
When an exercise fails, avoid immediately copying a replacement command. Identify whether the problem is a wrong assumption, an unavailable prerequisite, an incorrect target, an unsuitable state, or a validation error. This reasoning is more transferable than memorizing a single correction.
Use documentation actively
Read the 19c Backup and Recovery User’s Guide with a question in mind. For every major procedure, locate its prerequisites, restrictions, expected outcome, and recovery considerations. Summarize those points in a short operational note.
Keep source notes separate from personal interpretations. The official guide is evidence for the procedure; your checklist is a preparation aid. This distinction helps prevent an unofficial shortcut from becoming something you mistakenly regard as an exam requirement.
How should you prepare for multitenant questions?
Study multitenant administration through relationships and consequences. Oracle’s scope includes container databases, pluggable databases, and application containers, together with creation, cloning, security, transportation, and backup and recovery. For each activity, identify which object is involved, what state it must have, and what administrative result should be verified.
A useful study session moves from architecture to operation. First draw the container relationships. Then work through a creation or cloning scenario, add a security decision, and finish with transportation or backup and recovery considerations. Explain why each step belongs at that point in the sequence.
Do not study multitenancy as a list of isolated features. A question can become difficult when a familiar operation is placed in a different container context or combined with security or recovery requirements. Practise spotting the context before choosing an action.
Questions to ask for every scenario
Ask four questions: What is the target container or database? What operation is being requested? What conditions must already be true? How will the result be verified? Add a fifth question when the scenario concerns security or recovery: what risk does the chosen operation introduce or address?
These questions are practical preparation tools. They do not represent a quoted Oracle question format, and they should not be used to predict the wording of live exam items. Their purpose is to make your reasoning explicit and expose gaps before the exam.
How should you study patching and upgrading?
Treat patching and upgrading as controlled change management. Oracle identifies installation, patching, and upgrading of Oracle Database and Oracle Grid Infrastructure for a standalone server as part of the preparation scope. Build a sequence that starts with the known environment and ends with post-change validation.
For each topic, distinguish what changes, what must be checked beforehand, what order the tasks follow, and what evidence confirms completion. If your notes contain only commands, add the purpose and validation condition for each command. That turns procedural memory into operational understanding.
Include deployment in the same review cycle because Oracle’s FAQ names deployment alongside multitenancy, backup and recovery, patching, and upgrading. A candidate who studies only recovery may overlook the lifecycle portion of the Administration II scope.
Avoid version-blind notes
Use Oracle’s 19c material where the source identifies it, and label any older Administration I notes clearly. Avoid merging instructions from different releases without checking their context. The goal is not to collect every version difference; it is to prevent a procedure learned for one environment from being applied automatically to another.
When a source does not establish a detail such as a current exam version, delivery policy, or scheduling condition, do not fill the gap with a remembered figure or an unofficial claim. Verify it through Oracle before making a booking decision.
What delivery details are confirmed?
Oracle’s Administration II learning path lists 1Z0-083 as an online certification exam with a two-hour duration. The supplied official research does not establish a current price, question count, passing score, language list, delivery vendor, or complete scheduling policy, so those details should be checked on Oracle before registration.
Do not confuse the Oracle Learn practice-exam lab instructions with the certification exam’s delivery rules. The practice page describes a separate lab workflow: scheduling is required to obtain lab time, and the page instructs learners to check back 12 hours before the lab starts for access credentials. Those instructions are useful for a practice lab but are not evidence of the certification exam’s check-in process.
The practice page also describes system and connection information for that learning activity, including supported browsers and an unshared internet connection. Because those details belong to the lab page, verify the requirements for your actual certification appointment separately rather than assuming the practice environment and exam environment are identical.
Schedule only after checking the official listing
Before paying or reserving a slot, confirm the exam title, code, current availability, delivery method, duration, and applicable path in Oracle’s registration system. Exam information can change, and the approved research does not provide a complete current registration record.
If you use Oracle’s official practice exam, remember that Oracle states an 80% or higher score is required to pass that practice exam. This is a benchmark for that practice assessment only, not evidence of the certification exam’s passing score.
What is a realistic study roadmap?
A practical roadmap has four phases: establish the baseline, learn the architecture, practise operational workflows, and validate readiness. Keep the phases flexible rather than assigning unsupported calendar durations. Move forward when you can explain and perform the relevant work, not merely when a date on a study plan arrives.
Use Oracle’s Administration II learning path as the spine of the plan. Add the recommended Backup and Recovery Workshop, Multitenant Architecture, and Oracle Database New Features training where your baseline shows a need. Use the official study guide to keep installation, patching, upgrading, RMAN, and multitenant administration in view.
Phase one: establish your baseline
Read the official scope once and create the matrix described earlier. Mark each skill as strong, partial, or unfamiliar. Then verify whether your certification route requires both 1Z0-082 and 1Z0-083 or whether the documented upgrade route may apply to your prior credential.
Take the official preparation course’s sample questions or practice assessment as a diagnostic. Review every uncertain answer, including answers you guessed correctly. The purpose of this phase is to identify study work, not to chase a number.
Phase two: learn the connected concepts
Study multitenant architecture before drilling its operations. Build a diagram of container, pluggable, and application-container relationships, then attach creation, cloning, security, transportation, and backup or recovery tasks to the relevant context.
In parallel, review RMAN strategy using the 19c Backup and Recovery User’s Guide. Write short explanations of the objective behind each recovery workflow. Finish this phase by reviewing deployment, installation, patching, and upgrading for the standalone-server context identified by Oracle.
Phase three: practise and troubleshoot
Perform controlled exercises rather than reading continuously. For every exercise, record the starting state, intended change, procedure, validation, and failure diagnosis. Rotate between multitenant and RMAN tasks so that you practise selecting the correct context instead of following one familiar sequence.
Use failure review deliberately. When a procedure does not work, explain the cause before consulting the solution. Then repeat the operation from a clean starting state. This is a practical recommendation designed to improve retention and diagnostic reasoning; it is not a promise about the content of any live exam item.
Phase four: make the scheduling decision
Schedule when you can explain the official domains, complete representative lab work without relying on copied instructions, and diagnose your own mistakes. If you still confuse container contexts or cannot explain why an RMAN strategy fits a recovery objective, continue studying before booking.
Immediately before scheduling, recheck Oracle’s current certification page for the exam status, delivery details, registration rules, and any path conditions. Keep the appointment decision separate from confidence generated by an unofficial question bank.
Which mistakes waste preparation time?
The most damaging mistakes are scope confusion, command-only memorization, and treating a practice result as certification evidence. Correct them by returning to Oracle’s named skills, explaining the purpose of each operation, and using practice assessments to expose gaps rather than predict a live score.
A second problem is studying topics in isolation. Multitenant backup and recovery, RMAN transportation, deployment, and upgrading all involve state and dependencies. Connect each topic to a starting condition and a validation step so that your notes reflect administration work rather than disconnected definitions.
A third mistake is relying on stale logistics. The supplied lab page contains event-specific messages, maintenance notices, and access instructions. Such text should not be treated as a current universal exam rule. Verify the current Oracle registration and appointment instructions when you are ready to book.
Do not use exam dumps
Leaked questions and exam dumps do not establish competence and should not be used as a preparation strategy. Memorizing recalled answers can also hide the exact weakness that the official scope requires you to address. Use Oracle’s published learning path, study guide, training, practice material, and product documentation instead.
Practice questions are valuable when you review the reasoning behind each answer. If you cannot explain why an option fits the database state and objective, mark the topic for study even if the answer was correct.
Do not invent a blueprint
The approved research does not provide domain percentages, question counts, or a certification passing score. Do not build a study plan around numbers from an unverified source. Use the official domain descriptions and your own evidence from practice and lab work to prioritize effort.
What should you do next?
Begin with Oracle’s Administration II learning path and the 2019 DBA study guide. Confirm your certification route, create the scope matrix, and mark the first two weak areas. Then use the official training and documentation to turn those areas into exercises with observable results.
For RMAN, open the 19c Backup and Recovery User’s Guide and build a recovery notebook covering strategy, duplication, transportation, and failure diagnosis. For multitenant administration, map the container relationships and work through the named operations. Add installation, patching, upgrading, and deployment to the same validation checklist.
When your preparation is complete, verify the current Oracle exam listing before scheduling. Confirm the title, code, online delivery information, two-hour duration, and any registration details shown at that time. Keep practice-lab access instructions separate from certification appointment instructions, and use only the official Oracle channels for final logistics.
Conclusion
1Z0-083 rewards preparation that connects architecture with controlled administration decisions. Use Oracle’s documented scope to organise study around multitenancy, RMAN, recovery diagnosis, deployment, patching, and upgrading; use lab work to test whether you can apply the ideas; and use practice assessments to locate gaps rather than memorise answers. Confirm your certification path and current scheduling information with Oracle before booking. That combination gives you a defensible readiness decision without relying on unsupported exam claims or leaked material.
