FREQUENTLY ASKED QUESTIONS

What clients ask us most often.

What is level-3 (N3) DBA support?

N3 support is an escalation tier, stepping in when levels 1 and 2 need deep expertise to resolve a complex incident. It relies on fact-based analysis (logs, metrics, traces) to identify the root cause and propose durable fixes, not just a temporary workaround.

Do you offer 24/7 on-call coverage?

Yes. An on-call arrangement can be set up based on your service-continuity requirements, with contracted response and resolution times. It can cover round-the-clock on-call or targeted time windows depending on the criticality of your environments.

Do you work only on Oracle Exadata, or other database systems too?

Oracle Exadata is our specialty, from deployment to production optimization. We also work on PostgreSQL, SQL Server and MySQL, particularly for cross-database migrations and modernization projects.

How does an Oracle-to-PostgreSQL migration work?

The typical approach includes schema and application-code compatibility analysis, a cutover strategy, regression testing, a detailed cutover plan and post-migration support to secure service continuity.

Do you work remotely or on-site?

Engagements are mostly remote. On-site presence can be arranged depending on context, criticality and your internal constraints.
