Oracle Consulting

Oracle is the backbone of mission-critical enterprise systems — but poorly managed, it becomes a heavy burden in both performance and licensing cost. From reading AWR reports to designing Data Guard, we bring years of production Oracle experience.

Improving your existing Oracle estate, reducing licensing costs, or planning a phased move to open source — we provide unbiased, measurement-driven consultancy on all three paths.

What we do

  • Performance diagnosis with AWR / ASH analysis and SQL tuning
  • Data Guard architecture with switchover/failover drills
  • RMAN backup strategy and restore testing
  • License usage analysis and cost reduction roadmap
  • Phased migration from Oracle to PostgreSQL/MySQL
  • Version upgrades and platform moves (on-prem ↔ cloud)

Frequently asked questions

Our Oracle licensing costs are too high — what are the options?

Three paths: simplify current usage to shrink the license footprint, move suitable workloads down to Standard Edition, or migrate gradually to PostgreSQL. We build the inventory and report the real cost and risk of each path — the decision stays yours.

How long does a move from Oracle to open source take?

Depending on application count and PL/SQL density, months — done in phases. Low-risk reporting workloads move first; critical OLTP goes last. A rollback plan exists at every stage — we do not recommend big-bang migrations.

We have Data Guard but have never tested it — is that normal?

Common but dangerous: an untested failover is a failover that won't work in a disaster. We put controlled switchover drills on the calendar, document the process and hand it over to your team.

Where do you look first in a performance problem?

The wait events in the AWR report tell the story: is it I/O, locking or bad SQL? We extract the top 10 most expensive SQL statements and examine their plans; more often than not a few query and index fixes change the system's fate.
