Our Oracle development services and consulting exist for organizations where the database runs payroll, processes transactions, and holds thirty years of business data. PL/SQL that's maintainable, not legacy spaghetti. RAC configurations that actually failover when tested. Autonomous Database migrations that preserve performance. We work inside Oracle — schemas, patches, HA, and cloud migration — with the discipline enterprise data demands.
Why Entalogics for Oracle
Every Oracle estate we audit has the same problems — patches two quarters behind, PL/SQL packages with 10,000 lines nobody dares refactor, RAC failover untested since initial setup, and a licensing model so complex nobody knows if they're actually compliant. Oracle is the most capable enterprise database. Most installations don't operate it like one.
Oracle ships Critical Patch Updates every quarter for a reason — security vulnerabilities, stability fixes, compliance requirements. We apply patches on schedule with tested rollback plans, not six months late because nobody scheduled the downtime window.
Business logic in packages. Data access in separate packages. No monster procedure doing five jobs at once. Refactorable, testable, maintainable PL/SQL that the next DBA can actually read without archaeology.
RAC for scale-out, Data Guard for disaster recovery. Switchover tested quarterly with measured RTO/RPO — not assumed to work because it was set up correctly once.
Autonomous Database for workloads that genuinely benefit from auto-tuning and auto-patching. On-prem or Exadata Cloud when compliance, latency, or licensing actually requires it. The decision comes from measurement, not a vendor's roadmap.
When Oracle, when not
Oracle licensing, support, and operational complexity exceed any other database platform, and the cost of getting it wrong compounds over decades. We'll tell you honestly on the first call what your Oracle estate actually needs.

What we build on Oracle
Eight ways this work shows up for real clients. Each one built for long-term stability, not just a clean go-live.
Packages, procedures, and functions built with proper separation of concerns. Legacy PL/SQL refactored into maintainable, testable units. No more 10,000-line procedures nobody wants to touch.
RAC for scale-out HA. Data Guard for cross-site DR. Switchover tested and documented, with RTO and RPO measured, not assumed.
On-prem to OCI Autonomous Database via Zero Downtime Migration. Performance baselined, PL/SQL validated, licensing optimized with BYOL.
AWR analysis, SQL Tuning Advisor, execution plan review, index strategy. Queries taking minutes reduced to seconds, with measured before-and-after evidence.
Quarterly CPU patches applied on schedule. Major version upgrades with AutoUpgrade. Every patch tested, documented, with a rollback plan ready before it ships.
Licensing audit, feature usage analysis, BYOL assessment, consolidation planning. Know exactly what you're licensed for before Oracle's own audit team does.
Backend performance tuning, PL/SQL customization, and integration work for organizations running EBS on Oracle Database. Stable underlying infrastructure for the application layer running on top of it.
Ongoing monitoring, patch scheduling, performance reviews, and incident response — so the estate we remediated doesn't quietly drift back into the compliance and stability problems we were hired to fix.
The playbook
Patterns from real enterprise Oracle estates, not Oracle University labs.
P01
Business logic in packages. Unit tested with utPLSQL. Test coverage on critical procedures. Refactored code that survives the next DBA handover.
P02
Applied in test, validated, promoted to production within the quarter. Rollback plan documented. No skipped quarters, no audit surprises.
P03
Switchover executed, RTO measured, RPO validated, documentation updated. The HA configuration that works when it needs to, not just when it was originally set up.
P04
AWR snapshots analyzed for top SQL, wait events, and resource contention. SQL Tuning Advisor recommendations validated and applied, with measured improvement on every change.
P05
ZDM for migrating to Autonomous Database or Exadata Cloud. Performance baselined before migration. PL/SQL compatibility validated. Cutover with near-zero downtime.
P06
`DBA_FEATURE_USAGE_STATISTICS` reviewed regularly. Features enabled but not licensed identified before Oracle does. BYOL assessment factored into every cloud migration's cost model.
Signature case
A regional bank on Oracle 19c on-prem — patches 9 months behind, AWR showing top SQL consuming 60% of CPU, Data Guard switchover untested for 2 years, and licensing compliance unknown. Applied patches, tuned top 15 SQL statements, tested Data Guard switchover, audited licensing, and migrated the reporting workload to Autonomous Database in 14 weeks. CPU utilisation dropped 40%. Switchover RTO confirmed at 45 seconds.
Before
19c, 9 months unpatched · top SQL at 60% CPU · DG untested · licensing unknown
After
19c patched + ADB for reporting · CPU −40% · DG RTO 45s verified · licensing compliant
