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.
IBM MQ Support
Last reviewed by Scott Sternloff
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.

Incident Triage
These are real symptoms from real IBM MQ production environments — and the first thing our engineers check when one comes in.
| Symptom you're seeing | What we check first | Typical resolution |
|---|---|---|
| Channel stuck in RETRYING, messages backing up on the XMITQ | CHLAUTH 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. | Under 1 hour |
| Queue manager will not start after a server or storage event | Whether 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. | 2–4 hours |
| Log filesystem filling, MQRC 2102 or 2192 returned to applications | The 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. | 1–3 hours |
| Applications getting MQRC 2009 CONNECTION_BROKEN intermittently | Client 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. | 1–2 hours |
| Messages arriving on the dead letter queue with no obvious cause | The 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. | Under 2 hours |
| Multi-instance queue manager failed over but clients did not follow | Whether 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. | 2–4 hours |
| Queue depth climbing on a clustered queue, one instance untouched | Cluster 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. | 2–4 hours |
| z/OS queue manager hitting page set expansion or CF structure full | Page 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. | 2–4 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
No add-on pricing for incidents. No per-ticket charges. One contract covers the whole surface.
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.
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.
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.
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.
MQ cluster repository topology, workload balancing behavior, multi-instance and RDQM failover validation, and disaster recovery runbooks that get tested rather than filed.
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.
Why AceMQ
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.
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.
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.
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.
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.
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.
Cloud, Kubernetes, bare metal, hybrid, and air-gapped — including environments where you can't give us outbound network access.
Escalation Path
Every tier reaches a senior IBM MQ engineer. There is no tier-1 triage layer to get through.
P1 escalation path
A replay of one P1, from the first page to the written root-cause analysis
15-minute P1 response, 24/7.
A response time, not a resolution time.
P1 opened, on-call engineer paged
Phone, email or Slack reaches the on-call senior engineer directly, whether the incident is in RabbitMQ, Kafka, Redis, PostgreSQL or Kubernetes. No web form, no tier-1 queue.
Senior engineer on your bridge
A senior engineer who already knows your environment joins a live bridge, so nobody has to re-explain your topology.
Specialists across the stack join
When an incident crosses components, the engineers who know each one join. For RabbitMQ, the path runs to the core team.
Written root-cause analysis
Root cause, the fix applied and the prevention steps, delivered after every P1.
Pricing
AceMQ IBM MQ support contracts typically run $24,000–72,000 a year, depending on SLA level, scope (number of clusters or nodes, and environments) and deployment (self-managed, cloud-managed or Kubernetes).
| What moves the price | How it changes the contract |
|---|---|
| SLA level | Business-hours cover costs less than 24/7 cover with a 15-minute emergency response. |
| Scope | More clusters or nodes, and more environments, make a larger contract. |
| Deployment | Self-managed, cloud-managed and Kubernetes estates need different amounts of hands-on work. |
Covering several technologies under one contract, for example RabbitMQ, Kafka and Redis, earns an aggressive discount.
Support In Practice
IBM MQ support, migration and assessment work from AceMQ. Each card links to the full write-up: the queue manager estate, what AceMQ diagnosed or changed, and the result, so you can see how a similar problem was handled.
International Payment Exchange Service
Reducing manual error-queue operations by improving retry handling, dead-lettering, and downstream flow management across RabbitMQ, BizTalk, and D365.
Global Technology Enterprise
AceMQ developed a multi-technology compliance strategy covering CVE patching for Kafka alongside RabbitMQ and IBM MQ deployments, creating a unified vulnerability management approach across the entire enterprise messaging stack.
Government / Law Enforcement Agency
AceMQ provided a support model and SLA comparison for a government agency evaluating alternatives to IBM MQ support, including 48-hour critical patch response commitments and compliance documentation capabilities.
Enterprise Organizations
AceMQ's IBM MQ TCO assessment quantifies licensing, operational, and risk costs of IBM MQ deployments and presents a structured comparison against open-source alternatives with AceMQ commercial support.
Retail Banking Group
A queue manager's recovery log filled several times a month and applications on unrelated queues got resource errors. AceMQ traced it to one batch consumer's open unit of work.
Global Management Consulting Firm
Moving from older or more rigid middleware to RabbitMQ patterns with architecture transition planning, interoperability, and phased cutover.
Support options
AceMQ offers IBM MQ support in four tiers, each handing more of the day-to-day work to AceMQ: 24/7 support and incident management for queue managers your team runs, proactive monitoring that catches log, certificate and channel problems first, managed IBM MQ on your own infrastructure, and fully managed IBM MQ on AceMQ infrastructure. Any IBM MQ version is covered in all four, on distributed platforms and z/OS.
You run it, we back you up
Best for: Teams that run IBM MQ themselves and need senior cover at 3am.
You run it, we watch it with you
Best for: Estates where an expired certificate or a full log is not an acceptable surprise.
We run it in your cloud or data centre
Best for: Regulated estates that must keep payment and transaction traffic inside their own boundary.
We host it and run it, as a service
Best for: Teams that want to keep IBM MQ without owning its operations.
| Who does what | Tier 1 24/7 support | Tier 2 Proactive monitoring | Tier 3 Managed, your infrastructure | Tier 4 Fully managed by AceMQ |
|---|---|---|---|---|
| Who runs IBM MQ day to day? | Your team | Your team, with AceMQ reviews | AceMQ | AceMQ |
| Where does it run? | Your infrastructure | Your infrastructure | Your cloud account or data centre | AceMQ infrastructure |
| 24/7 incident response | 15-minute P1 response | 15-minute P1 response | 15-minute P1 response | 15-minute P1 response |
| Health checks and CVE alerts | On request | Scheduled | Included | Included |

Every Tier can start as an ad hoc engagement or an annual partnership, and you can move up or down a Tier as your team changes.
One partner for IBM MQ
Support is one part of what AceMQ does for IBM MQ. The same engineers deliver consulting, health checks, migrations and end-of-life cover, and support the systems that usually run next to it.
IBM MQ support covers 24/7 emergency incident response with a 15-minute SLA, written root cause analysis on every P1, TLS and CHLAUTH configuration work, certificate lifecycle tracking, performance and log tuning, cluster and HA design review, and version upgrade support. Every ticket is handled by a named senior engineer assigned to your account, with no tier-1 triage layer and no per-incident charge.
Yes. We support IBM MQ on Linux, AIX, Windows, IBM i, and z/OS. The z/OS environment is genuinely different — page sets and buffer pools instead of queue files, queue-sharing groups backed by the Coupling Facility, and shared message data sets for large payloads. Vendors that treat z/OS as distributed MQ with different filenames get this wrong, and it shows during an incident.
P1 emergencies — queue manager down, channels refusing to start, messages stalled on a transmission queue — get a 15-minute first response with a senior engineer joining a live bridge. P2 critical issues are 1 hour, P3 high-priority 4 hours, and P4 standard questions next business day. These are contractual commitments, not best-effort targets.
Yes, and most of our IBM MQ customers keep both. IBM support handles product defects and supplies fixes. What it does not do is join your bridge at 3am to work out why your channel stopped after a firewall change, or tune your buffer pools against your workload. We handle the operational and configuration side and will drive a PMR with IBM on your behalf when a genuine product defect is involved.
Yes. We support versions past their IBM end-of-support date, including WebSphere MQ 7.x estates, with workarounds and mitigations where official fixes are no longer available. Regulated environments frequently cannot upgrade on the vendor's timeline. We will also give you an honest read on which specific risks that leaves open, so the decision to stay is a deliberate one.
Yes, and we will tell you honestly whether you should. We plan and execute migrations from IBM MQ to RabbitMQ or Kafka with zero message loss, including transactional semantics mapping, parallel-run validation, and phased cutover. We also regularly advise customers that their MQ estate is sound and a migration would cost far more than fixing what is actually wrong. The diagnosis comes first.
There are three support options. IBM Software Subscription and Support, bought through Passport Advantage, is the standard entitlement: fix packs, new versions and access to IBM support for a version that is inside its support window. IBM extended support is a paid extension for a version that has gone out of support, with a limited scope and a limited term. Third-party support, which is what AceMQ provides, covers operations, troubleshooting and incident response on any version of IBM MQ, IBM MQ Advanced, the IBM MQ Appliance and older WebSphere MQ, and runs alongside IBM or on its own. IBM also ships the product in two streams, Long Term Support and Continuous Delivery, and the support window differs between them, so check which one each queue manager is on.
End of support means IBM stops producing fixes for that version, including security fixes, and IBM support will no longer take a case on it unless you buy an extension. The software keeps running. The risks accumulate quietly: vulnerabilities in the MQ software, the bundled Java runtime and TLS components stay open, the operating system underneath eventually moves past what that MQ version is certified on, and auditors in regulated industries treat unsupported middleware as a finding. There are also licensing implications if entitlement lapses while the software is still installed. The practical answer is a dated plan: support in place for the version you run today, and a tested upgrade to the latest version on a Long Term Support release.
Yes. It is one product family with three names. MQSeries became WebSphere MQ, and WebSphere MQ was renamed IBM MQ at version 8.0 in 2014. Queue managers, channels and the programming interfaces carried through each rename, which is why estates that began on MQSeries still run today. We support all of them, including the platform-specific parts: multi-instance queue managers and clustering on distributed platforms, the architecture differences on z/OS, and the installation and configuration detail that changes between versions.
Yes. AceMQ works on IBM MQ in two ways: ad hoc engagements for a defined piece of work, such as a health check, an upgrade or an incident, or an annual partner engagement that covers 24/7 support, proactive reviews and named engineers. Many teams start ad hoc and move to an annual partnership once the first engagement is done.
Every AceMQ proposal is tailored to your requirements: your IBM MQ environment, the SLA you need, the hours of cover and the scope of work. Most contracts run $24,000–72,000 a year, depending on the SLA, the scope and how IBM MQ is deployed, with aggressive discounts when several technologies share one contract.
