Python ibmmq lib: Support retrieving CCDT from DNS TXT Records apart from File, HTTP, HTTPS

IBM® MQ clients can currently retrieve CCDT information from a local file, FTP, HTTP, and HTTPS. While functional, these approaches rely on static files or external hosting, which adds complexity in modern cloud and container environments.

We propose allowing MQ clients to retrieve CCDT information directly from DNS TXT records.

With this enhancement, a client would specify a DNS name (for example,
<qmgrName>.mq.ms.com) using an environment variable such as MQCCDTURL or a new variable like MQCCDTDNS. The MQ client library would resolve the DNS TXT records and use the returned data exactly as it does today when reading a CCDT from a file or URL.

Benefits

  • Eliminates the need to distribute or manage CCDT files

  • Enables dynamic, DNS‑based service discovery

  • Fits naturally with cloud, container, and hybrid deployments

  • Requires no application code changes

  • Behaves consistently with existing CCDT support

Summary

Adding DNS TXT record support as a CCDT source would provide a lightweight, modern alternative for MQ client configuration, improving flexibility and operational simplicity while remaining fully backward compatible.
