IBM MQ Support

24/7 IBM MQ Support with a 15-Minute Emergency SLA

AceMQ supports IBM MQ in production on distributed platforms and z/OS — channels stuck in RETRYING, queue managers that won't start after a filesystem event, log filling under long-running units of work, and TLS handshakes that broke after a certificate rotation. Every ticket reaches a named senior engineer who already knows your queue manager topology.

Escalation Path

Your first hour of a IBM MQ outage

Most vendors publish an SLA number. This is what actually happens, minute by minute, when you page a senior AceMQ engineer.

T+0

You page us

Phone, email, or Slack — any channel reaches the on-call senior engineer directly. No web form, no tier-1 queue.

T+15

Named engineer live

A senior engineer who already knows your environment joins a live bridge. Zero cold-start, no re-explaining your topology.

T+30

Root cause isolated

Direct broker access, log and metric review, and a working hypothesis with a rollback plan before we touch anything.

Post

Written RCA

Documented root cause, the fix applied, and the prevention steps — delivered after every P1, not just when asked.

Response Times

SLA tiers, contractually guaranteed

Every tier reaches a senior IBM MQ engineer. There is no tier-1 triage layer to get through.

P1 — Emergency
15 min

Production down, messages not flowing, cluster or broker failure

P2 — Critical
1 hour

Severe degradation, rising error rates, approaching capacity limits

P3 — High
4 hours

Performance issues, configuration problems, non-critical failures

P4 — Standard
Next day

Questions, guidance, best practices, non-urgent improvements

Incident Triage

IBM MQ problems we fix every week

These are real symptoms from real IBM MQ production environments — and the first thing our engineers check when one comes in.

Channel stuck in RETRYING, messages backing up on the XMITQ
What we check firstCHLAUTH rules blocking the inbound connection, TLS CipherSpec mismatch between the sender and receiver ends, and whether the receiver channel hit MAXINST or MAXINSTC. The AMQERR01.LOG reason code separates these in seconds — guessing does not.
Typical resolutionUnder 1 hour
Queue manager will not start after a server or storage event
What we check firstWhether the recovery logs and queue files are intact and the qm.ini log path still resolves. Most failed starts are a filesystem permission change, a missing mount, or a media recovery that needs the correct linear log extents restored in order.
Typical resolution2–4 hours
Log filesystem filling, MQRC 2102 or 2192 returned to applications
What we check firstThe oldest active log extent and what is pinning it — nearly always one long-running uncommitted unit of work holding a transaction open. We identify the connection and application before touching log configuration.
Typical resolution1–3 hours
Applications getting MQRC 2009 CONNECTION_BROKEN intermittently
What we check firstClient heartbeat and keepalive settings against firewall or load balancer idle timeouts. An intermediary silently dropping idle sockets is the single most common cause, and it appears intermittent because it tracks traffic troughs.
Typical resolution1–2 hours
Messages arriving on the dead letter queue with no obvious cause
What we check firstThe DLH reason code on the message header itself — MQRC 2053 queue full, 2085 unknown object name, and 2035 not authorized point at three completely different fixes. We read the header before we look anywhere else.
Typical resolutionUnder 2 hours
Multi-instance queue manager failed over but clients did not follow
What we check firstWhether the standby actually acquired the lock on the shared filesystem, and whether the client CCDT or connection name list includes both instances. A failover that works at the queue manager layer and not at the client layer is a CCDT distribution problem.
Typical resolution2–4 hours
Queue depth climbing on a clustered queue, one instance untouched
What we check firstCluster workload balancing state — CLWLPRTY, CLWLRANK, and whether the quiet instance's cluster-receiver channel is actually running. A partial repository that lost its full repository connection stops receiving cluster updates without erroring.
Typical resolution2–4 hours
z/OS queue manager hitting page set expansion or CF structure full
What we check firstPage set usage against the buffer pool it maps to, and for shared queues, the Coupling Facility structure size and offload rules to SMDS or DB2. Page set 0 pressure is a different problem from application page set pressure and needs a different fix.
Typical resolution2–4 hours

Resolution times reflect typical IBM MQ engagements under an active AceMQ support contract. Every P1 closes with a written root-cause analysis.

What's Included

Everything in your IBM MQ support contract

No add-on pricing for incidents. No per-ticket charges. One contract covers the whole surface.

Emergency Incident Response

Queue manager down, channels not starting, or messages stalled on a transmission queue. A senior IBM MQ engineer joins a live bridge within 15 minutes with access to diagnose — not a ticket acknowledgement.

Root Cause Analysis

Every P1 closes with a written RCA including the relevant AMQERR log extracts, the reason codes involved, the fix applied, and the configuration change that prevents recurrence.

TLS, CHLAUTH & Certificate Lifecycle

Key repository management, CipherSpec selection as IBM deprecates older suites, CHLAUTH rule design, and certificate renewals planned before expiry rather than diagnosed at 2am after one.

Performance & Log Tuning

Buffer pool and page set sizing, circular versus linear logging decisions, log extent sizing against transaction duration, and channel batch tuning against your actual message profile.

Cluster & High Availability Design

MQ cluster repository topology, workload balancing behavior, multi-instance and RDQM failover validation, and disaster recovery runbooks that get tested rather than filed.

Version Upgrades & Migration

Upgrades across LTS and CD release streams, WebSphere MQ legacy version migration, moves to MQ on containers or IBM MQ on Cloud, and migration off MQ to RabbitMQ or Kafka where that is the right call.

Anywhere You Run It

We support IBM MQ wherever it's deployed

Cloud, Kubernetes, bare metal, hybrid, and air-gapped — including environments where you can't give us outbound network access.

Why AceMQ

What you get that you don't get elsewhere

Named Engineers, Zero Cold Start

The same senior engineers stay on your account. They know your queue manager names, your cluster layout, and which applications sit behind which channels — so a P1 call starts with diagnosis, not you reading out your topology.

No Tier-1 Triage Layer

You reach a senior IBM MQ engineer directly by phone, email, or Slack. Nobody collects a problem description to pass along, and there is no queue between you and someone who can read an AMQERR log and a FDC file.

Distributed and z/OS, Both Deeply

Most vendors staff one or the other. We support distributed platforms and MQ for z/OS, including shared queues on the Coupling Facility and the queue-sharing group behavior that has no equivalent on distributed.

Genuine Follow-the-Sun Coverage

Engineers across 26+ countries and every time zone. Your 3am incident is someone's mid-afternoon — no overnight skeleton crew, no waiting for a region to wake up.

Proactive, Not Just Reactive

Quarterly health checks on your queue managers plus certificate expiry tracking. A large share of the MQ outages we see are certificates nobody was watching, and that is a preventable class of incident.

Full-Stack, Not Just the Queue Manager

MQ problems are frequently not MQ problems. We diagnose across the OS, filesystem and storage latency, network policy, load balancer idle timeouts, and the JMS or .NET client — which is where a surprising number of MQRC 2009s actually originate.
