ROSTAN Technologies is an Oracle Gold Partner supporting live Oracle ERP estates for Illinois businesses — manufacturing, distribution, logistics and financial-trading firms across the Chicago area running Oracle EBS or Fusion Cloud. Our Application Managed Services cover the full run-state of an Oracle system after go-live: incident resolution, patching, performance tuning, Oracle DBA work, month-end close support and small enhancements, against an agreed SLA.
Support is delivered by our Oracle practice in India — we do not have an Illinois office, and we do not claim one. India is roughly 10.5–11.5 hours ahead of Central Time, so a ticket logged at the end of a Chicago business day is already being worked when our team starts, giving Illinois clients real overnight progress rather than a next-morning queue.
Chicago-area manufacturing and distribution businesses lean heavily on Order Management, Purchasing, Inventory and Manufacturing modules. Support is scoped around supply-chain uptime, not just finance close.
Central Time sits roughly 10.5–11.5 hours behind India. Issues raised in the afternoon or evening in Chicago are picked up as our team starts its day, so overnight progress is the norm, not the exception.
For businesses where Oracle downtime stops trucks moving or orders shipping, response time on P1 incidents matters more than almost anything else in the SLA. Our escalation path is built around that reality.
For stable Illinois EBS estates evaluating a move off Oracle Premier Support, our own service desk data — 6,245 Oracle tickets across 27 months — is public on our main Oracle AMS page, so you can see what actually generates support load before you commit.
Illinois clients get the same L1, L2 and L3 model, the same module coverage and the same operating discipline described on our main Oracle Application Managed Services page — root-cause tracking rather than "issue resolved", problem management for repeat tickets, and monthly service reporting you can audit.
That page also publishes the real workload breakdown from our own service desk: 6,245 Oracle tickets across 11 enterprise environments over 27 months, and what they were actually about.
