IBM Z software trial is now available for IMS

An IMS client can use a preconfigured IMS environment to try out guided scenarios that demonstrate real-world use cases. These virtual trials are offered at no cost.

Some of the scenarios available now include:

• IMS Enterprise Suite Explorer for Development - access IMS data by issuing SQL statements and using IMS catalog.
• IBM z/OS IMS Ansible collection - try out the automation capabilities of Ansible by issuing IMS commands.
• Ansible sample playbooks - automate the configuration of IMS managed ACBs and catalog using Ansible.

Learn more and register for an IBM Z trial.

Preview program available for IMS Explorer

IMS Explorer Web UI support - An IMS application developer, system programmer or database administrator can use IMS Explorer from a Web-based integrated development environment that helps to ease installation and to make IMS Explorer more accessible.

Fixed as of August 2024

Users Affected: All IMS V15 DB/TM and DCCTL users of MFS with BUFNO= specified on the IMS FORMATA/B data set DD statements and APAR PH49046 applied.

Problem description: ABEND878 due to insufficient CTL region 24-bit storage after APAR PH49046 (PTF UI91893).

Additional problem summary: After APAR PH49046 (PTF UI91893), an extra buffer pool in 24-bit control region private storage is gotten for the IMS MFS FMTLIB data sets if BUFNO= is coded on the FORMATA / FORMATB DD cards. The size of this buffer is based on the number of buffers on BUFNO, and the block size of the FMTLIB data sets. This will increase 24-bit private usage in the control region, and can result in an ABEND878 or other storage abends if 24-bit storage is exhausted, depending on the current 24-bit storage usage.

Circumvention: Remove BUFNO=xx from the IMS FORMATA/B data set DD statements.
