IMS Transaction Manager details

COBOL and Java™ Interoperability

Accelerate application modernization with COBOL and Java interoperability by extending existing 31-bit IMS COBOL applications or write new applications with Java in 64-bit mode.

Open Transaction Manager Access (OTMA) enhanced storage management

Applications with heavy OTMA transaction processing will have reduced storage requirements including enhanced TPIPE storage management.

IMS support for z/OS Workload Interaction Correlator

Reduce time to identify and resolve anomalies based on unified workload insights.

Pervasive encryption for IMS OSAM Databases: 64-bit support

Modifications to OSAM Media Manager support 64-bit addresses, which mitigate 31-bit storage constraints.

Performance enhancement for IMS TM and Db2 customers using RACF

System programmers can make RACF® calls at a region level for IMS transactions being sent to Db2®.

Do not stop IMS Fast Path transaction and program on application abend

Provides the option to prevent an IMS transaction and program running in a message-driven IFP region from stopping after an application abend.

Java Database Connectivity (JDBC) hex and binary literal support

Provides hex and binary literal support in SQL queries running against the IMS Universal Drivers.

IBM Z Security and Compliance Center

IMS coupled with IBM Z Security and Compliance Center running on IBM® z16™ streamlines your compliance workflow and removes the ambiguity from audits.

IMS Database Manager details

IMS Native z/OS DDL utility

IMS 15.3 makes it easier to use or submit DDL without the need for IMS Connect and Open Database Manager (ODBM).

Database Recovery Control (DBRC) facility staging directory command support

Provides the ability to register a new database with DBRC and verify changes before importing changes to the active directory.

Non-structural catalog changes without an outage

Users in an IMS managed application control block (ACB) environment now have the ability to implement non-structural changes to the IMS catalog without having to take the catalog offline.

Catalog purge utility

Ability to purge non-active and non-pending instances from the catalog while IMS is online so there is no sacrifice to availability.

IMS catalog API enhancement

Simplifies access to IMS metadata through enhanced catalog API capabilities.

Increase of Data Entry Database (DEDB) areas

Manage larger workloads and store up to 5x more data in a single DEDB.

DDL audit trail in readable format

Ability to collect audit information related to changes made to IMS metadata using DDL, so you can view exactly what resource changes were made by whom and when, in an easily readable form.

General Sequential Access Method (GSAM) Library Build utility

Provides the ability for IMS users of managed ACBs to create GSAM database descriptors (DBDs) and program specification blocks (PSBs) that contain GSAM PCBs and sources of them using the IMS Catalog Library Builder utility.
