01

Tell us your scope

Share your environment — version, RAC or single instance, what you need and how urgent it is. A quick WhatsApp message or the form below is enough to get started.

Get a clear quote

We review the scope and send a tailored quote — hourly, weekly, monthly or fixed for a project — with no obligation. You know exactly what you're paying before any work begins.

03

Senior DBA on the job

Once you're happy, we schedule the session or set up your engagement and get to work — screen-share, remote access or guided support, whatever your security setup allows.

Client outcomes

What clients say

★★★★★

Our standby had been lagging for two days and our team was stuck. One session — root cause found in the redo transport, fixed, and documented so we could prevent it. Exactly what senior help should look like.

Arif RahmanARArif RahmanOracle DBA · Jakarta
★★★★★

The performance audit paid for itself in the first week — the AWR review found two runaway SQLs our monitoring never flagged, and the overnight batch window shrank dramatically after the fixes.

Elena PetrovaEPElena PetrovaDatabase Engineer · Prague
★★★★★

We handed over day-to-day administration of nine databases on a monthly retainer. Patching is on schedule, backups are tested, and my developers finally stopped doing DBA work on the side.

Before you ask

Services — frequently asked

How quickly can support begin?
Message us on WhatsApp with your issue — replies typically come within a few hours, 7 days a week (business hours 10 AM – 8 PM IST). For production emergencies, mark the message URGENT and we prioritise it; once scope and quote are agreed, work can often begin the same day.
Do you sign an NDA?
Yes — we're happy to sign your NDA before you share any environment details. Confidentiality is standard practice for every engagement, with or without one.
Do you support Oracle Cloud (OCI) and Exadata?
Yes. We work across on-premises, Exadata and OCI — including migrations between them, cloud architecture reviews and hybrid DR designs.
Can you troubleshoot RAC and Data Guard issues?
That's our home ground — node evictions, interconnect issues, SCAN/listener problems, standby lag, switchover and failover drills. We also teach these topics in our RAC and Data Guard live courses.
How do we give you access securely?
Whatever your security policy allows: screen-share where your team drives, or time-boxed access via your VPN with credentials you control and revoke. We don't store credentials after the engagement.
Do you work weekends and off-hours?
Yes — patching, upgrades and cutovers usually have to happen in off-hours windows, and we plan engagements around your maintenance calendar, including weekends.
What does it cost?
Every environment is different, so pricing is by quote — hourly rescue, weekly project cover or a monthly retainer. Tell us your scope in the quote form and you'll get a clear price before any work begins.
