ActiveMQ Backup and Disaster Recovery: Complete DR Guide
A message broker's backup and disaster recovery plan is the last line of defense against scenarios that HA cannot address: a full datacenter outage, catastrophic hardware failure that destroys both primary and secondary nodes, accidental message deletion, or KahaDB corruption that prevents the broker from starting.

ActiveMQ JVM Memory & GC Tuning: Heap Sizing, G1GC, ZGC Guide
The JVM is the runtime foundation of every ActiveMQ deployment. Message throughput, delivery latency, producer flow control triggers, OOM crashes, and GC-induced delivery pauses all trace back to JVM memory configuration. Yet ActiveMQ ships with a 512MB heap and no GC logging, appropriate for a developer laptop, not for an enterprise message broker handling millions of messages a day.

ActiveMQ Monitoring & Alerting Setup: The Complete 2026 Guide
Most ActiveMQ outages are not sudden failures. They are visible in the metrics for minutes, sometimes hours, before they become incidents. A memory usage graph climbing past 60%. A queue depth that isn't draining. An enqueue time that doubled after a deployment. A consumer count that dropped from 3 to 1 at 2 AM.

ActiveMQ JMS 2.0 Implementation Guide: Simplified API, Transactions & Spring
For most of JMS's lifetime, writing a simple producer required creating a ConnectionFactory, creating a Connection, starting it, creating a Session, creating a MessageProducer, creating a Message, calling send(), and then closing the producer, session, and connection with the close calls safely wrapped in finally blocks to prevent resource leaks. Every developer knew the pattern. Every developer wrote it slightly differently. Every code review had the same comments about resource management.

ActiveMQ Security Hardening: TLS, JAAS, LDAP & CVE Patch Guide
In October 2023, security researchers published CVE-2023-46604, a CVSS 10.0 remote code execution vulnerability in Apache ActiveMQ. Within days, it was being actively exploited in ransomware campaigns. The attack required nothing more than network access to port 61616. No authentication, no credentials, no social engineering. The attacker connected to the standard ActiveMQ port and executed arbitrary code on the server.

From Middleware to Mission Control: How Transaction Visibility Turns into Operational Intelligence
In today’s digital enterprises, middleware isn’t just infrastructure—it’s the heartbeat of every mission-critical operation. Yet too often, it operates as an invisible black box. This article explores how organizations can transform middleware management into true Operational Intelligence—gaining complete transaction visibility, intelligent automation, and unified governance. Discover how meshIQ turns complex messaging environments like Apache Kafka®, MQ, and Solace into a strategic business advantage.
