OIC - Direct File Polling using File Adapter in Oracle Integration Cloud (OIC)

✅ Overview

OIC supports direct file polling using the File / FTP / SFTP Adapter to automatically trigger an integration when a file arrives in a folder.

This pattern is used for real-time file integration without scheduling.

---

🎯 Use Case

A customer receives files (CSV/XML/TXT) in an SFTP or file server folder and needs OIC to:

• Automatically trigger integration when file arrives
• Filter files by name pattern
• Read and process each file
• Archive or delete after processing
• Avoid scheduled polling

Important Limitation:

Dynamic directory path is NOT supported in direct polling mode.
The polling folder must be a fixed path in the adapter trigger.

      ⬇
Target System (ERP/HCM/DB/API/Storage)

---

⚙️ Adapter Properties

📍 Directory & File Filters

Property	Purpose
Input Directory	Folder to poll (must be fixed)
File Name Pattern	Wildcard match (*.csv, *.xml, Invoice_*.txt)
Read Files Recursively	Include subfolders
Rejection Directory	For non-matching files

---

⏱️ Polling Behavior

Property	Purpose
Polling Frequency	How often OIC checks for files
Processing Delay	Delay before reading (file write completion)
Maximum Files	Limit files per poll cycle

---

🗃️ File Handling

Property	Purpose
Delete Files After Successful Read	Remove file post-process
Ignore File-Not-Found on Delete	Avoid errors during concurrent moves
Archive / Error Directory	Folder to move processed/failed files

---

🧩 Dynamic Directory — Clarification

Capability	Status
Dynamic folder for polling	❌ Not supported
Fixed directory required in trigger	✅ Yes
Dynamic directory possible in scheduled list-read flow	✅ Yes

Conclusion:

Use Direct Polling only when folder path is static.
Use Scheduled Integration + List Files when folder needs to be dynamic (lookup-based).

---

🚀 Solution Steps

1️⃣ Create File / SFTP Adapter with Polling

• Enter Base Directory (mandatory)
• Enable Read, List, Move/Delete
• Save credentials & security config

---

2️⃣ Create App-Driven Orchestration

• Trigger → File Adapter
• Operation → Read File in Trigger/Polling Mode
• Configure:
  • Input Directory
  • File Pattern (Example: *.csv)
  • Archive & Error folders

---

3️⃣ Build Flow Logic

• Read File → Map → Process to target
• Add logging & validation
• Move / Delete file after success

---

4️⃣ Error Handling

• Fault-handler block
• Move file to error folder
• Send notification (Email/Teams/SMS)
• Audit integration logs

---

✅ Outcome

Benefit	Details
Real-time automation	No scheduler needed
Reliable file execution	Archive/error segregation
Controlled polling	Based on adapter properties
Platform aligned	Follows OIC capability & constraints

---

📌 When to Use Which Model

Requirement	Recommended
Real-time fixed folder	Direct File Polling Trigger
Different folders per env	Multiple connections OR deploy-wise config
Dynamic folder path needed	Scheduled + List Files Action

---

📝 Key Takeaway

OIC File Adapter Direct Polling = Static Folder + Event-Style Trigger
Dynamic Directory = Only via Scheduled integration

Microsoft Excel - Working with an excel list

Understanding Excel List Structures

An Excel list (table) is a structured set of rows and columns used to store related data (like employee info, sales records).

• Each column has a heading
• Each row is a record
• Helps in sorting, filtering, and analyzing data easily

---

Sorting a List Using Single-Level Sort

Sort based on one column only.
Steps:

1. Click any cell in the column you want to sort
2. Go to Data tab
3. Choose Sort A→Z (ascending) or Z→A (descending)

Example: Sort employees by Name alphabetically.

---

Sorting a List Using Multi-Level Sorts

Sort based on more than one column.
Steps:

1. Select the list
2. Data → Sort
3. Add first sort level (e.g., Department)
4. Click Add Level and add second sort level (e.g., Salary)

Example: First sort by Department, then sort each department by Salary.

---

Using Custom Sorts in an Excel List

Use custom order instead of A-Z or numbers.
Steps:

1. Data → Sort
2. Choose column
3. Under Order, select Custom List
4. Pick preset lists (Mon, Tue, Wed…) or create your own

Example: Sort months as Jan, Feb, Mar… instead of alphabetical order.

Microsoft Excel - Excel Formula to Check if Data Exists Across Sheets (Missing or Present)

✅ Excel Formula to Check if Data Exists Across Sheets (Missing or Present)

💡 Use Case

In integration or data-tracking scenarios, you often maintain two different sheets — for example,

• one with a master list of interfaces, and
• another with a subset list you want to verify.

You need to automatically check whether each interface in your current sheet exists in the master sheet, and mark it as “Present” or “Missing.”

---

⚙️ Formula Used

=IF(COUNTIF('OIC Interfaces'!F:F, H2) = 0, "Missing", "Present")

---

🧠 Formula Breakdown

Part	Meaning
COUNTIF('OIC Interfaces'!F:F, H2)	Counts how many times the value in cell H2 appears in column F of the sheet named ‘OIC Interfaces’.
= 0	Checks if the count is zero — meaning the value doesn’t exist in that column.
"Missing"	Returned when the value is not found in the target sheet.
"Present"	Returned when the value is found in the target sheet.
IF(...)	Combines the logic to display either “Missing” or “Present.”

---

🪜 Step-by-Step Solution

1. Identify your reference sheet – for example, 'OIC Interfaces' is your master list of integrations.
2. Choose the lookup column – here, column F in 'OIC Interfaces' contains the unique identifiers or interface names.
3. Write the formula in your working sheet – in cell N2, enter the formula to check if H2 exists in the master list.
4. Copy down the formula – Excel will automatically check all rows and mark each as “Present” or “Missing.”

---

🧩 Example

Sheet 1: Working Sheet

H (Interface Name)	Result
ERP_GL_Extract	(Formula result)
EPM_SFTP_Load	(Formula result)

Sheet 2: OIC Interfaces

F (Interface Name)
EPM_SFTP_Load
HCM_Payroll_Extract

Now when you use the formula:

=IF(COUNTIF('OIC Interfaces'!F:F, H2)=0,"Missing","Present")

✅ For ERP_GL_Extract, Excel shows “Missing”
✅ For EPM_SFTP_Load, Excel shows “Present”

---

🏁 Final Takeaway

This simple IF + COUNTIF combination is one of the most practical Excel tricks for:

• Validating data consistency across multiple sheets
• Checking missing records between reports
• Comparing lists during integrations or reconciliations

It’s lightweight, dynamic, and works perfectly for ERP, OIC, or data validation reports.

Microsoft Excel - VLOOKUP Use Case

🔍  Excel VLOOKUP Use Case - Fetching Data Across Sheets

📘 Use Case

You have data stored in multiple sheets — for example, integration details in one sheet (FileBasedIntegrations_SFTPMAIL) and a list of integration names in another.
You want Excel to automatically fetch matching details (like mail ID, file path, or status) based on the integration name.

---

💡 Formula Used

=VLOOKUP(F2, FileBasedIntegrations_SFTPMAIL!A:J, 9, 0)

---

⚙️ Step-by-Step Explanation

Step	Meaning
Step 1: Identify lookup value (F2)	This is the value Excel will search for — located in cell F2 (for example, the Integration Name).
Step 2: Define table array (FileBasedIntegrations_SFTPMAIL!A:J)	This is the range where Excel will search. Here, it looks in column A of the sheet FileBasedIntegrations_SFTPMAIL and can return data from columns A through J.
Step 3: Set column index number (9)	Excel will return the value from the 9th column in the specified range, corresponding to the row where the lookup value was found.
Step 4: Specify match type (0)	The 0 (or FALSE) means exact match — Excel will only return a result if it finds an exact match for the lookup value in column A.

---

🧩 Example

Let’s say you have a lookup setup like this:

Sheet 1 (Main Sheet):

Integration Name	Details
PAYROLL_EXTRACT	(Formula here)

Sheet 2 (FileBasedIntegrations_SFTPMAIL):

A (Integration Name)	...	I (SFTP Mail ID)
PAYROLL_EXTRACT	...	hr_sftp@company.com
FINANCE_REPORT	...	finance_sftp@company.com

Now, when you enter this formula in Sheet 1:

=VLOOKUP(F2, FileBasedIntegrations_SFTPMAIL!A:J, 9, 0)

If F2 contains PAYROLL_EXTRACT, Excel searches column A in FileBasedIntegrations_SFTPMAIL, finds the matching row, and returns the value from column 9 — here, hr_sftp@company.com.

---

✅ Solution Summary

• VLOOKUP connects data across sheets using a shared key (like an ID or name).
• It saves time, reduces manual searching, and maintains consistency in large Excel reports.
• Ideal for ERP, HR, and Integration tracking spreadsheets where details are stored in separate tables.
