OCI 1Z0-1093-25 Study Plan: 30, 60, and 90 Days

OCI 1Z0-1093-25 30-, 60-, and 90-day study plan with topic order, review loops, and final-week priorities.

This plan is built around the database-services loop: classify workload -> choose boundary -> separate resilience options -> check day-2 ownership.

How to use this plan well

Each study block should do four things:

  1. classify the scenario as workload fit, security boundary, resilience, or operations
  2. choose the Oracle service or control that belongs there
  3. do a short scenario set
  4. write down whether the miss came from wrong service fit, confused resilience language, or ignored operations ownership

	  Classify["Classify workload / boundary / resilience / operations"] --> Choose["Choose Oracle service or control"]
	  Choose --> Drill["Do short scenario set"]
	  Drill --> Review["Review why misses happened"]
	  Review --> Classify

How long should you study?

Typical candidates need 80 to 140 focused hours.

Your time Recommended timeline Good fit
18 to 22 hrs/week 30 days intensive path with recent Oracle database experience
10 to 14 hrs/week 60 days balanced path for most candidates
6 to 9 hrs/week 90 days part-time path with slower reinforcement

30-day intensive plan

Week Focus Output
1 service selection, workload fit, and provisioning models service-fit notes and drills
2 security, networking, least privilege, and auditability boundary tie-break sheet
3 backup, restore, HA, DR, and migration safety resilience notes and mixed sets
4 database management, monitoring, patching, and final compression mixed review and readiness check

60-day balanced plan

Phase Weeks Focus
1 1 to 2 workload fit and provisioning boundaries
2 3 to 4 security, networking, and governance
3 5 to 6 backup, recovery, HA, DR, and resilience trade-offs
4 7 migration, database management, and operations ownership
5 8 weak-lane repair and mixed review

90-day part-time plan

Month Focus Goal
1 service-selection and provisioning vocabulary stop losing points to fit confusion
2 security and resilience boundaries get stronger at safe default choices
3 migration, operations, and exam-style tie-breaks finish with mixed-set confidence

If misses cluster here, do this next

Miss pattern Weak lane Fix next
you keep picking the wrong database platform workload fit review service model and management-boundary differences
you assume managed means secure enough security and ops review private access, least privilege, and auditability
you use backup, HA, and DR interchangeably resilience review recovery language and failure-scope differences
you talk about migration tools but not cutover risk migration review validation, downtime, rollback, and dependency timing

What strong prep usually does

  • classifies the workload first instead of defaulting to the most powerful database option
  • keeps a short confusion table for backup vs HA, HA vs DR, and service feature vs service fit
  • writes down what the team still owns even when the service is managed
  • uses Oracle docs to settle disputed boundaries, then comes back here for compression

Final 72 hours

Keep doing Stop doing
rereading the cheat sheet and glossary opening unrelated new database services
reviewing service-fit and resilience misses treating performance marketing as the whole answer
checking Oracle docs for disputed boundaries using backup, HA, and DR as if they mean the same thing
practicing workload -> boundary -> resilience -> operations order trusting unsupported community summaries over Oracle docs

Route yourself well
