Oracle E-Business Suite on Oracle Database@Azure
Oracle E-Business Suite on Oracle Database@Azure
Article Overview
Oracle E-Business Suite is one of the most demanding workloads an enterprise runs — a large, chatty, latency-sensitive database under a multi-node application tier, carrying customisations accumulated over years. Moving it to Oracle Database@Azure is attractive precisely because it lets the EBS database land on Exadata inside the Azure datacenter, next to the Azure services the rest of the business already uses. This article is a practical guide to doing that well: the split-tier architecture that keeps the application on Azure VMs while the database runs on Exadata, which database configurations are actually certified, the migration methods and how to choose between them, the licensing arithmetic, and the operational realities of running EBS on this platform once the cutover is done. The emphasis throughout is on what is genuinely different about EBS — because a generic database migration guide will quietly mislead you here.
1.Why EBS on This Platform
E-Business Suite has a particular relationship with its database that most applications do not. The EBS data model is enormous, the workload mixes heavy batch (concurrent programs) with interactive OLTP, and performance is exquisitely sensitive to the round-trip latency between the application tier and the database. That combination is exactly what Exadata was built for — and it is why running the EBS database on Oracle Database@Azure, rather than on a general-purpose Azure VM, is such a natural fit.
The strategic appeal is that you no longer have to choose between Oracle's best database platform and Microsoft's cloud. The EBS database gets Exadata — Smart Scan, RAC, the storage engine EBS batch loves — while the whole thing sits inside Azure, integrated with Azure networking, identity, and monitoring, close to any Azure analytics or AI services you want to point at your ERP data. For an Oracle-heavy enterprise standardising on Azure, that removes the awkward compromise that used to define these projects.
EBS is not a generic database workload. It is a latency-sensitive, batch-heavy, customisation-laden system where the database platform and the network between the tiers make or break performance — which is exactly why Exadata inside Azure is compelling.
The one thing to internalise first
On this platform, EBS becomes a split-tier deployment: the database moves to Exadata on Oracle Database@Azure, while the EBS application tier keeps running on Azure virtual machines that you manage. Almost every architecture, migration, and operations decision in this article flows from that single split. Hold it in mind and the rest follows logically.
2.The Split-Tier Architecture
The defining characteristic of EBS on Oracle Database@Azure is that the two tiers live on two different kinds of infrastructure, connected over the Azure network. Understanding this picture is the foundation for everything else.
2.1 Who owns what
| Component | Runs on | Managed by |
|---|---|---|
| EBS web / Forms / OHS (WebLogic) | Azure VMs | You (application DBA / platform team) |
| Concurrent Processing (batch) | Azure VMs | You |
| Shared application filesystem (APPL_TOP) | Azure NetApp Files / shared NFS | You |
| EBS database (CDB/PDB) | Exadata on Oracle Database@Azure | You (database), Oracle (Exadata infra) |
| Exadata infrastructure | Oracle Database@Azure | Oracle |
| Networking, identity, monitoring | Azure | You |
The application tier does not move — it re-homes
A common misunderstanding is that "moving EBS to Oracle Database@Azure" means moving everything. It does not. The database moves to Exadata; the application tier is rebuilt or re-hosted on Azure VMs and re-pointed at the new database. Thinking of it as a database migration plus an application-tier re-home — two related but distinct pieces of work — keeps the project scoped correctly.
3.Supported Configurations
This is the section where guessing gets you in trouble, because EBS certification is specific and it moves. The headline facts — verified against Oracle's support policies at the time of writing — are worth getting exactly right, then always re-checking against My Oracle Support for your release before you commit.
3.1 What is certified
| Dimension | Position at the time of writing |
|---|---|
| EBS release | E-Business Suite 12.2 is the release with support policies for Oracle Database@Azure |
| Database service | Exadata Database Service on Dedicated Infrastructure — the mainstream target |
| Autonomous option | Certified on Autonomous Database on Dedicated Infrastructure (ADB-D); not on Autonomous Database Serverless (ADB-S) |
| Database version | Oracle Database 19c and the current AI Database (26ai), per the EBS certification matrix |
| Application tier | Runs on Azure VMs that you provision and manage |
| Oracle RAC / Data Guard | Available through the Exadata platform for HA and DR |
⚠️ ADB-Serverless is not certified for EBS — do not assume it is
One of the easiest and most expensive mistakes here is to reach for Autonomous Database Serverless because it sounds like the most modern, hands-off option. For EBS it is not certified. EBS on Autonomous is supported on Autonomous Database on Dedicated Infrastructure (ADB-D). If you want the autonomous management model, ADB-D is the certified path; otherwise Exadata Database Service on Dedicated Infrastructure is the mainstream choice. Always confirm on My Oracle Support before designing around any option.
3.2 Choosing among the certified targets
Exadata Database Service (ExaDB-D)
The mainstream target for a large production EBS database — dedicated Exadata with full control over the database, RAC, and Data Guard. The default choice when you want maximum control and the classic Exadata experience.
Autonomous Database Dedicated (ADB-D)
The certified autonomous path for EBS — Oracle automates patching, tuning, and security on dedicated Exadata. Choose it to minimise DBA overhead, accepting the autonomous operating model.
Exadata Exascale (ExaDB-XS)
The elastic, lower-entry Exadata option. Its ability to scale ECPUs down makes non-production EBS environments cost-effective — useful for dev/test that can shrink out of hours. Confirm EBS certification for your case.
3.3 Database Release Updates matter more than usual
EBS certifies against specific Database Release Updates (RUs), and Oracle has moved to making only the latest 19c and 26ai RUs available through the console by default. Before migrating, check the EBS-certified RU for your target version, confirm it is applied, and run the EBS Database Parameter Checker (EDBPC) to validate the database initialisation parameters against EBS requirements. The certification is at the RU level, not just the major version — treat it that way.
4.Network and Latency
For most applications, a few extra milliseconds between tiers is invisible. For EBS it is not. The application tier and database exchange an enormous number of round trips — concurrent programs and Forms sessions are famously chatty — so the latency of the SQL*Net path between the Azure VMs and the Exadata database is one of the biggest determinants of how EBS feels and how fast batch runs.
4.1 Keep the tiers close
The single most important network rule is to place the EBS application VMs and the Oracle Database@Azure database in the same Azure region, and ideally aligned to the same availability zone as the database's primary, so the SQL*Net round trip stays as short as possible. The database is provisioned into a delegated subnet in your VNet; the app-tier VMs sit in the same VNet, and traffic between them stays on the Azure backbone.
| Network element | What to get right for EBS |
|---|---|
| Region co-location | App VMs and database in the same region — non-negotiable for batch performance |
| Zone alignment | Align the app tier to the database primary's zone to minimise cross-zone hops |
| VNet and delegated subnet | Database in its delegated subnet; app VMs in the same VNet for backbone-speed traffic |
| Network security groups | Open the SQL*Net port (typically 1521) between app subnet and database subnet only |
| Shared filesystem | Low-latency shared storage (e.g. Azure NetApp Files) for a shared APPL_TOP across app nodes |
✅ Measure the round trip before and after
Do not assume the network is fine — measure it. Capture a representative concurrent-program run and a Forms transaction profile on the source, then reproduce them after migration and compare. A batch job that got slower almost always traces to more or slower round trips between the tiers, and catching that in testing — not after go-live — is the difference between a smooth cutover and a war room.
5.Migration Approaches
Migrating the EBS database to Oracle Database@Azure uses the same family of Oracle tools as any database migration — but the right choice is shaped by EBS realities: database size, acceptable downtime, the source and target database versions, and whether you must cross endianness or upgrade in flight. Here are the main methods and where each fits.
| Method | How it works | Best when |
|---|---|---|
| Data Guard / physical standby | Build a standby on the target, sync, then switch over | Same version and endianness; smallest downtime for large databases |
| Zero Downtime Migration (ZDM) | Oracle's orchestration tool automates the physical or logical move | You want a guided, repeatable migration with minimal manual steps |
| Data Pump (expdp/impdp) | Logical export/import of schemas and data | Smaller databases, cross-version or cross-platform, or selective moves |
| RMAN / cross-platform transportable | Backup-based or transportable tablespace movement | Very large databases or endianness/platform changes |
| GoldenGate (near-zero downtime) | Replicate changes live, cut over when caught up | Minimal-downtime requirement on very large or busy databases |
5.1 The EBS wrinkle: it is rarely just a database move
A crucial EBS-specific point: migrating the database is often bundled with a database upgrade (for example 19c to 26ai) and always with re-homing the application tier. If you are changing database version as part of the move, the EBS-prescribed upgrade path — using AutoUpgrade and the EBS-provided upgrade documents — governs the sequence, and the certified RU must be in place. Plan the migration and any upgrade as one coordinated exercise, not two.
🔧 Let downtime tolerance pick the method
The clean way to choose is to work backwards from allowable downtime. A large EBS production database with a tight cutover window points at Data Guard or GoldenGate for near-zero downtime; a smaller or non-critical instance can take the simpler Data Pump path. ZDM is the orchestration layer that makes the physical approaches repeatable. Size, version change, and downtime together select the method — do not default to the tool you know best.
6.A Migration Runbook
Here is a practical sequence for an EBS migration to Oracle Database@Azure, using a Data Guard physical standby for the database (the common minimal-downtime choice) plus the application-tier re-home. Adapt the specifics to your release and downtime window; the shape holds.
STEP 1Prepare the target and validate certification
Provision the Exadata VM cluster on Oracle Database@Azure, confirm the certified Database RU for your EBS release, and run the EBS Database Parameter Checker against the intended configuration.
# On the target Exadata database: confirm version and RU level
sqlplus / as sysdba <<'EOF'
SELECT banner_full FROM v$version;
SELECT description FROM dba_registry_sqlpatch ORDER BY action_time DESC FETCH FIRST 3 ROWS ONLY;
EOF
# Validate init parameters against EBS requirements (EDBPC per MOS)
# Then confirm the delegated subnet / VNet connectivity from the app subnet:
tnsping EBSPROD_AZURE # from an app-tier VM — must resolve and connect
nc -zv <scan-hostname> 1521 # SQL*Net port reachable from app subnetSTEP 2Build the standby on the target
# On the target: create a physical standby from the on-prem/source primary
rman TARGET sys@EBSPROD_SOURCE AUXILIARY sys@EBSPROD_AZURE
DUPLICATE TARGET DATABASE
FOR STANDBY
FROM ACTIVE DATABASE
DORECOVER
SPFILE
SET db_unique_name='EBSPROD_AZ'
SET control_files='+DATA/EBSPROD_AZ/control01.ctl'
NOFILENAMECHECK;
# Then configure Data Guard broker and start managed recovery
dgmgrl sys@EBSPROD_SOURCE
ADD DATABASE 'EBSPROD_AZ' AS CONNECT IDENTIFIER IS EBSPROD_AZURE MAINTAINED AS PHYSICAL;
ENABLE CONFIGURATION;
SHOW CONFIGURATION; # confirm SUCCESS and applied-through SCN advancingSTEP 3Prepare the application tier on Azure VMs
Stand up the EBS application-tier VMs in the same VNet, lay down the application filesystem on shared storage, and get everything ready to re-point at the new database — without cutting over yet.
# On the Azure app-tier VMs:
# * provision VMs in the same region/zone as the DB primary (availability set)
# * mount shared APPL_TOP on Azure NetApp Files / shared NFS
# * install the EBS tech stack matching the source
# * pre-stage the context file changes for the new DB host/port/service
# * DO NOT run autoconfig against the new DB until cutoverSTEP 4Cut over
# 1. Quiesce EBS: shut down the source application tier (stop batch + web)
adstpall.sh apps/<pwd>
# 2. Final redo apply, then switch the standby to primary
dgmgrl sys@EBSPROD_SOURCE "SWITCHOVER TO 'EBSPROD_AZ'"
# 3. Re-point the EBS app tier at the new database and regenerate config
# (update the context file with the new DB host/SCAN/service, then:)
adautocfg.sh # AutoConfig on the DB tier + app tier
adstrtal.sh apps/<pwd> # start the app tier against the new DB
# 4. Validate: logins, a concurrent request, a Forms transaction, key reportsSTEP 5Validate and stabilise
Run the post-cutover validation set — user logins through SSO, a representative concurrent program, a Forms transaction, month-end-style reports — and compare timings against the pre-migration baseline captured earlier. Keep the source recoverable until you have signed off.
⚠️ AutoConfig and the context file are where EBS migrations trip
Unlike a plain database move, EBS carries its topology in the context file, and AutoConfig regenerates hundreds of configuration files from it. The most common cutover failure is a context file that still points at the old database host, port, or service name. Prepare the new values in advance, run AutoConfig on both tiers after switchover, and validate that the application is genuinely talking to the new database — not silently still reaching the old one.
Rehearse the whole runbook end to end
Do a full dry run against a copy, timing every step, before the real cutover. EBS migrations have many moving parts — database switchover, context file changes, AutoConfig, app-tier restart, validation — and the rehearsal is where you find the missing grant, the firewall rule, or the AutoConfig surprise while they are still cheap. The real cutover should be the second time you have done it, never the first.
7.Licensing and Sizing
Licensing is where EBS-on-Azure projects are quietly won or lost, because the arithmetic differs sharply between native Azure VMs and Oracle Database@Azure — and in Database@Azure's favour.
7.1 The ratio that changes the business case
On native Azure VMs, Oracle's policy counts two vCPUs as one processor license, and you must license the VM's full vCPU count. On Oracle Database@Azure with Exadata services, the bring-your-own-license ratio is materially more efficient: eight ECPUs map to one Oracle processor license. For a database as large as a typical EBS production instance, that difference compounds into a substantially better licensing position on Database@Azure than on general-purpose Azure VMs.
| Placement | Licensing basis |
|---|---|
| Oracle DB on native Azure VM (BYOL) | 2 vCPUs = 1 processor license; license the VM's full vCPU count |
| Oracle Database@Azure, Exadata (BYOL) | 8 ECPUs = 1 processor license — materially more efficient |
| Oracle Database@Azure, License Included | Database software bundled into the hourly service rate |
7.2 BYOL versus License Included
Two commercial models apply. Bring Your Own License (BYOL) suits enterprises with an existing Oracle license estate — you apply owned licenses at the efficient Exadata ratio. License Included (LI) bundles the database software (Enterprise Edition plus key options) into the hourly rate, which fits short-lived environments, workloads needing options you do not own (such as RAC), or net-new adopters without an existing estate. For EBS, many enterprises run production BYOL and spin up non-production LI.
⚠️ Model licensing before you size, and involve procurement early
Sizing and licensing are entangled: the shape you pick drives the license count, and your existing entitlements shape which model is cheapest. If you are inside an Unlimited License Agreement, deploying heavily on Database@Azure during the term can leave you under-certified at expiry — a genuinely serious trap. Bring procurement and licensing specialists in at the design stage, not after you have sized the platform.
8.High Availability and DR
EBS on this platform inherits the same HA and DR building blocks covered in depth elsewhere on this blog — but the EBS angle is that both tiers need protecting, in coordination.
| Layer | Availability | Disaster recovery |
|---|---|---|
| Database | Oracle RAC across Exadata nodes — node failure does not take the database down | Active Data Guard standby, cross-zone or cross-region |
| Application tier | Multiple app-tier VMs in an availability set, behind a load balancer | A parallel app tier in the DR region, ready to point at the standby |
| Shared filesystem | Redundant shared storage for APPL_TOP | Replicated to the DR region |
| Backups | Autonomous Recovery Service (or Object Storage) for the database; protect app-tier VMs separately | |
DR for EBS is a two-tier drill, not a database failover
The trap is to treat EBS DR as just a Data Guard failover. It is not — a failed-over database with no application tier serves no users. A real EBS DR plan brings up the standby database and the DR-region application tier, re-points the app tier at the new primary via AutoConfig, and validates the full stack. Rehearse it end to end, both tiers, exactly as you would the migration cutover.
9.Day-Two Operations
Once EBS is live on Oracle Database@Azure, the operating model is a split of responsibilities that is worth being explicit about, because things fall through the cracks precisely where ownership is fuzzy.
| Operational area | How it works on this platform |
|---|---|
| Exadata infrastructure | Oracle operates the underlying Exadata — hardware, storage cells, infrastructure patching |
| Database administration | You run the database: parameters, schemas, performance, EBS-specific database tasks |
| Application tier | You run the EBS app tier on Azure VMs — patching the tech stack, concurrent managers, scaling |
| Monitoring | OCI database metrics and audit logs surface natively in Azure; combine with Azure Monitor for the app tier |
| Identity | Microsoft Entra ID for Azure resources; integrate EBS user authentication as your standards require |
| Backups | Oracle-managed database backups; Azure-side protection for the app VMs |
9.1 Monitoring that spans both tiers
Because the OCI database metrics and audit logs are natively available in Azure, you can watch the database and the app tier from the Azure monitoring stack you already use — giving one place to correlate an app-tier slowdown with a database wait or a concurrent-manager backlog. Set this up early; the value of unified monitoring shows up during the first incident, not the first demo.
-- Concurrent Processing health: anything stuck or backing up?
SELECT phase_code, status_code, COUNT(*) AS requests
FROM apps.fnd_concurrent_requests
WHERE requested_start_date > SYSDATE - 1
GROUP BY phase_code, status_code
ORDER BY requests DESC;
-- Are the concurrent managers actually running as configured?
SELECT concurrent_queue_name, max_processes, running_processes
FROM apps.fnd_concurrent_queues
WHERE enabled_flag = 'Y'
ORDER BY concurrent_queue_name;
-- Top EBS sessions by wait, right now (DB tier)
SELECT s.sid, s.module, s.action, s.event, s.wait_class
FROM v$session s
WHERE s.status = 'ACTIVE' AND s.username = 'APPS'
ORDER BY s.wait_class;Own the seam between "you" and "Oracle"
The riskiest part of any managed-platform operating model is the seam — the point where Oracle's responsibility for the Exadata infrastructure meets your responsibility for the database and app tier. Know exactly where that line is, who to call for what, and how infrastructure maintenance windows are communicated, so that when something happens you are not discovering the boundary during the incident.
10.Patching and Cloning
Two recurring operational jobs deserve their own note because EBS makes them distinctive: keeping the database on a certified RU, and cloning environments.
10.1 Patching to stay certified
EBS certifies against specific Database Release Updates, and with only the latest 19c and 26ai RUs surfaced through the console by default, staying certified means applying the EBS-certified RU deliberately rather than drifting. The discipline: check the certified RU for your EBS release, apply it following the EBS-provided database patch instructions, run the EBS Database Parameter Checker afterward, and validate the application. Treat "certified" as an RU-level, ongoing property — not a one-time box tick at migration.
Coordinate database and application patching
On a split-tier EBS deployment, database patching (on the Exadata side) and EBS application patching (on the Azure VMs) are separate streams that must stay compatible. Plan them together, in a non-production environment first, and confirm the combination is certified before applying to production. The failure mode is patching one tier into an unsupported combination with the other.
10.2 Cloning for dev/test
EBS teams live on clones — refreshing test and dev from production constantly. On this platform, a clone is a database copy (from a backup or a standby) attached to a cloned application tier, with EBS cloning procedures (adcfgclone and AutoConfig) reconfiguring the copy for its new identity. The Exascale option is attractive for non-production precisely here: environments that can scale their ECPUs down out of hours keep the cost of a fleet of clones manageable.
# On the cloned application tier (after the DB copy is available):
# 1. lay down the cloned APPL_TOP on the target's shared storage
# 2. run EBS clone configuration against the new database
perl adcfgclone.pl appsTier # reconfigures the app tier for the clone
# 3. AutoConfig regenerates config from the clone's context file
adautocfg.sh
# 4. bring up and validate the cloned environment
adstrtal.sh apps/<pwd>
# The clone must point at the CLONED database, never production — verify.⚠️ The clone that points at production
The classic, dangerous cloning error is a test environment that ends up connected to the production database because a context file or TNS entry was not fully reconfigured. On a platform where production is a valuable managed database, verify explicitly — every time — that a freshly cloned app tier is talking to the cloned database and nothing else, before anyone runs a test transaction against it.
11.EBS-Specific Pitfalls
| Pitfall | Why it bites, and the fix |
|---|---|
| Assuming ADB-Serverless is certified for EBS | It is not — EBS on Autonomous is certified on ADB-Dedicated; verify on My Oracle Support first |
| Treating certification as version-level | EBS certifies against specific Database RUs — check and apply the certified RU, run EDBPC |
| Ignoring tier-to-tier latency | EBS is chatty — co-locate app VMs and database in the same region/zone and measure the round trip |
| Forgetting the context file / AutoConfig | EBS topology lives in the context file — prepare new values, run AutoConfig on both tiers at cutover |
| Planning DR as a database failover only | A failed-over DB with no app tier serves nobody — DR must bring up both tiers and re-point them |
| Sizing before licensing | The 8-ECPU ratio and BYOL/LI choice change the economics — model licensing at design time |
| Migrating and upgrading as separate afterthoughts | Version change follows the EBS upgrade path — plan migration and upgrade as one exercise |
| Cloning without verifying the target | A clone can silently connect to production — verify the cloned app tier points at the cloned DB |
| Never rehearsing the cutover | EBS cutovers have many parts — do a full timed dry run before the real one |
| Fuzzy ownership at the managed seam | Know exactly where Oracle's responsibility ends and yours begins, before an incident |
Almost every EBS-specific pitfall comes from treating EBS like a generic database. It is not: the context file, the certification granularity, the chatty tiers, and the two-tier DR are what make it EBS — respect them and the platform rewards you.
12.Frequently Asked Questions
Does the whole of EBS move to Oracle Database@Azure?
No. The database moves to Exadata on Oracle Database@Azure; the EBS application tier is re-homed onto Azure VMs that you manage. It is a database migration plus an application-tier re-home — two related pieces, one project.
Which EBS release and database versions are supported?
E-Business Suite 12.2 has the support policies for Oracle Database@Azure, running on Oracle Database 19c or the current AI Database (26ai) per the EBS certification matrix. Certification is at the Database Release Update level, so confirm the exact certified RU on My Oracle Support for your release.
Can I run EBS on Autonomous Database?
Yes, but only on Autonomous Database on Dedicated Infrastructure (ADB-D), which is certified for EBS 12.2. Autonomous Database Serverless (ADB-S) is not certified for EBS. If you want the autonomous model, ADB-D is the certified path.
What is the mainstream target for a large production EBS database?
Exadata Database Service on Dedicated Infrastructure — dedicated Exadata with full control over the database, RAC, and Data Guard. ADB-D is the certified autonomous alternative; Exascale is attractive for cost-effective non-production.
How do I migrate with minimal downtime?
For a large production database, a Data Guard physical standby (build, sync, switch over) or GoldenGate replication gives near-zero downtime. Data Pump suits smaller or cross-version moves, and ZDM orchestrates the physical approaches. Let your downtime tolerance and any version change pick the method.
Why does latency between the tiers matter so much for EBS?
EBS exchanges a very high number of round trips between the application tier and the database — concurrent programs and Forms are chatty. So SQL*Net latency directly shapes batch and interactive performance. Co-locate the app VMs and database in the same region and zone, and measure the round trip before and after.
How does licensing compare to native Azure VMs?
Favourably. On native Azure VMs the ratio is two vCPUs per processor license across the whole VM; on Oracle Database@Azure Exadata the BYOL ratio is eight ECPUs per processor license — materially more efficient for a database the size of EBS. License Included is also available for environments that suit it.
What is the biggest EBS-specific risk in the migration?
The context file and AutoConfig. EBS carries its topology in the context file, and a cutover that does not correctly regenerate configuration for the new database host, port, and service is the classic failure. Prepare the new values, run AutoConfig on both tiers, and verify the app is talking to the new database.
13.Key Takeaways
The short version
• It is a split-tier deployment. The database runs on Exadata in Oracle Database@Azure; the EBS application tier is re-homed onto Azure VMs you manage. Every decision flows from that split.
• Get certification exactly right. EBS 12.2 on Exadata Database Service (Dedicated) or ADB-Dedicated — not ADB-Serverless — on 19c or 26ai, at the certified Database RU. Verify on My Oracle Support.
• Latency between the tiers is decisive. Co-locate app VMs and database in the same region and zone, and measure round trips before and after — EBS is chatty.
• Choose the migration method by downtime. Data Guard or GoldenGate for large, low-downtime moves; Data Pump for smaller or cross-version; plan any upgrade as part of the move.
• Model licensing at design time. The 8-ECPU-per-license Exadata ratio and the BYOL/LI choice materially change the business case; involve procurement early.
• Respect the EBS specifics. Context file and AutoConfig at cutover, two-tier DR, RU-level patching, and careful cloning — these are what make EBS different from a generic database.
Running Oracle E-Business Suite on Oracle Database@Azure resolves a tension Oracle-heavy enterprises have carried for years: it puts the EBS database on the Exadata platform it was practically designed for, while keeping the whole environment inside Azure and close to the rest of the estate. The database gets Smart Scan, RAC, and the storage engine EBS batch thrives on; the organisation gets Azure networking, identity, monitoring, and proximity to Azure analytics and AI — without the old compromise between the two clouds.
The work that makes it succeed is not exotic, but it is EBS-specific. Keep the tiers close and measure the latency. Nail the certification down to the Release Update. Choose the migration method from your downtime budget, and treat any version change as part of the same exercise. Do the licensing arithmetic before you size. And respect the things that make EBS itself — the context file, AutoConfig, two-tier DR, disciplined patching and cloning. Handle those with care and Oracle E-Business Suite runs on this platform not as a reluctant lift-and-shift, but as a genuinely modern deployment of a system your business has depended on for a very long time.
E-Business Suite certification, supported database versions and Release Updates, Autonomous Database support, licensing ratios, and platform capabilities reflect Oracle and Microsoft documentation and My Oracle Support policies available at the time of writing and change frequently — always verify current certification and support details on My Oracle Support for your specific EBS release before designing or migrating. All commands and scripts are illustrative, use placeholder names and values, and must be validated against your own environment, versions, and current documentation before use.
