🧭 Supported Upgrade Paths

✅ From EBS 12.2.x

You can directly apply the 12.2.14 RUP on top of your existing 12.2.x environment using Online Patching.

❌ From EBS 12.1.x

You must first upgrade to EBS 12.2 base release, then apply 12.2.14.

⚙️ Architecture Advantage – Online Patching

EBS 12.2 uses Edition-Based Redefinition (EBR) and ADOP Online Patching, allowing:

• Patching while users remain connected

• Minimal downtime during cutover

• Safer rollback options

• Parallel patch execution

This architecture makes large upgrades feasible even for 24x7 systems.

🛠 Phase 1 – Pre-Upgrade Preparation (Most Critical Step)

🔹 1. Environment Baseline Check

Verify:

• Current EBS version & patch level

• Database version (19c strongly recommended)

• OS certification (RHEL 7 / RHEL 8 supported)

• Adequate disk space on APPL_TOP, FS1, FS2, DB

---

🔹 2. Apply Mandatory Pre-Req Patches

Before 12.2.14, ensure:

• Latest AD Delta Patch

• Latest TXK Delta Patch

• Latest Online Patching support patches

Check with:

SELECT patch_level FROM fnd_product_installations WHERE application_id = 0;

---

🔹 3. Clean Online Patching Environment

Verify edition health:

SELECT edition_name, usable FROM dba_editions;

Cleanup old sessions:

adop cleanup

Confirm no failed sessions:

adop status

---

🔹 4. Backup Strategy (Mandatory)

Before starting:

• Full RMAN database backup

• Application tier backup

• Snapshot / AMI backup in cloud

• Save context files and config files

---

🚀 Phase 2 – Apply 12.2.14 RUP Using ADOP

Step 1 – Prepare Phase

adop phase=prepare

Step 2 – Apply Phase

adop phase=apply patches=36026788 workers=8

Monitor:

adop status

Step 3 – Finalize Phase

adop phase=finalize

Step 4 – Cutover Phase

adop phase=cutover

Step 5 – Cleanup Phase

adop phase=cleanup

---

🧪 Phase 3 – Post-Upgrade Validation

🔹 Technical Validation

• Check application services

• Verify forms and OAF pages

• Confirm concurrent managers

• Validate edition switching

Check invalid objects:

SELECT owner, object_name, status FROM dba_objects WHERE status='INVALID';

---

🔹 Functional Validation

With business users:

• Login and navigation

• Core transactions

• Interfaces and reports

• Month-end / critical flows

---

⚠️ Common Issues Observed in Real Projects

From production experience:

🔹 Edition Errors

• ORA-38803 / ORA-38818
  Usually fixed by:

• Cleaning failed adop sessions

• Re-running finalize / cleanup

---

🔹 Performance Issues After Upgrade

Fix by:

• Re-gathering stats

• Validating profile options

• Reviewing JVM and heap settings

---

🔹 Patch Conflicts

Avoid by:

• Applying latest AD/TXK before RUP

• Not mixing multiple one-off patches

---

📈 Best Practices & Recommendations

✔ Always upgrade in DEV → TEST → PROD
✔ Keep a detailed upgrade tracker
✔ Involve functional users early
✔ Avoid patching during month-end
✔ Keep rollback strategy ready
✔ Document everything for audit & support
