OpenText Network Operations Management (NOM) — Automation

Blog Series: OpenText NOM — Part 4

➡ Part 1 — SNMP Explained
➡ Part 2 — Network Discovery & Monitoring
➡ Part 3 — Event & Incident Management

After monitoring and incident handling, mature NOC environments move to the next stage: Automation.

Automation transforms operations from reactive → proactive → self-healing.

📌 Why Automation Matters

Manual operations cause:

  • Slow resolution

  • Human errors

  • Night shift workload

  • Repetitive tasks

Automation enables:

✔ Faster recovery
✔ Reduced MTTR
✔ Consistent operations
✔ Predictable infrastructure behavior

🖼️ Reactive vs Automated Operations


Types of Automation in NOM

1️⃣ Event-Driven Automation

Action triggered automatically when an event occurs.

Example:

If interface down → restart port

Flow:
Event → Rule → Script → Resolution

2️⃣ Runbook Automation

Predefined procedures executed automatically.

Typical tasks:

  • Clear interface errors

  • Restart service

  • Flush ARP cache

  • Collect diagnostics

🖼️ Runbook Execution

3️⃣ Self-Healing Actions

System resolves issue without human intervention.

Example:

High CPU detected → restart process → verify recovery

4️⃣ Scheduled Automation

Periodic maintenance tasks:

  • Config backup

  • Health check

  • Log cleanup

  • Compliance verification

Automation Workflow

  1. Event detected

  2. Policy matched

  3. Script executed

  4. Validation performed

  5. Ticket updated

🖼️ Automation Flow

Integration with External Tools

Automation can trigger:

  • SSH commands

  • REST APIs

  • Scripts

  • Configuration tools

Example Scenario

Problem: Disk usage exceeds 90%

Automation steps:

  1. Detect threshold breach

  2. Clean temporary files

  3. Restart service

  4. Verify normal usage

  5. Close incident

No operator needed.

Benefits in NOC

Without Automationwith Automation
Manual responseAutomatic recovery
Alert stormsControlled resolution
High MTTRLow MTTR
Human fatigueStable operations

Best Practices

✔ Start with safe actions
✔ Always validate after action
✔ Avoid destructive commands
✔ Log automation results
✔ Implement approval workflows

📚 Recommended Reading

🎯 Conclusion

Monitoring detects problems.
Incident management organizes response.
Automation resolves issues automatically.

This is the transition from monitoring → autonomous operations.

Modern NOCs aim for self-healing infrastructure.

OOPs Concepts in Java | English | Object Oriented Programming Explained

Image
🔹OOPS (Object Oriented Programming System) in Java Object-Oriented Programming (OOPS) is a programming paradigm that uses classes and objects to design software. It simplifies development and maintenance by applying key concepts: 📌 Class: Class   is a user-defined data type which defines its properties and its functions. Class is the only logical representation of the data. For example, Human beings in an organisation is a class like Employee. The age, name, department, salary etc. of a human being/employee are its properties, and the jobs performed by the employees in an organisation are known as functions.  The class does not occupy any memory space till the time an object is instantiated. A class is a user-defined data type that defines properties and functions. For example: Class: Employee Properties: name, age, salary Functions: work(), attendMeeting() A class does not occupy memory until an object is created. ...

Scopes of Signal in jBPM

Image
💡 Introduction Signals in jBPM 7 are a core part of event-driven workflow design. They allow asynchronous communication between process instances, making it possible to start , interrupt , or coordinate processes without direct linking. However, signals can have different scopes , which define how far the signal travels and who receives it . Let’s explore the four available scopes in detail: 🔹 Process Scope 🔹 Default Scope 🔹 External Scope 🔹 Project Instance Scope 🧩 1️⃣ Process Scope 📘 Definition Process scope signals are local to a single process instance or its child subprocesses . They are not visible outside that instance hierarchy. 📋 Use Case Used for communication inside the same process , like triggering subprocesses or event sub-processes. 🖼️ Process Scope Example Below is an example of a simple process-scoped signal. Only this process (or its subprocess) will catch this signal. ⚙️ 2️⃣ Default Scope 📘 Definition The default scope ...

jBPM Installation Guide: Step by Step Setup

  jBPM Installation Guide – Step by Step for Beginners If you are starting with jBPM (Java Business Process Management) , the first step is to set up your environment. In this guide, we’ll walk through how to install jBPM, configure it, and run your first business process. 🔎 What is jBPM? Before we dive into installation, a quick recap: jBPM is an open-source Business Process Management (BPM) suite , written in Java, that allows you to model, execute, and monitor workflows using BPMN 2.0 standards. It can run standalone , embedded in applications , or deployed on a Java EE server . 🖥️ Prerequisites Before installing jBPM, make sure you have: Java JDK 11 or later (Java 17 is commonly used) Maven 3.x (for building and managing dependencies) Git (optional, if you want to clone sample projects) A Database (H2, MySQL, PostgreSQL, or Oracle) – jBPM ships with H2 for testing At least 4GB RAM (8GB recommended for Workbench & KIE Server) 📦 Download ...
