IMS 15.5 system continuous delivery functions
IMS 15.5 system functions are delivered using PTFs as part of the IMS continuous delivery enhancement process and allow you to use new enhancements faster and more frequently.
| Function description | APAR, PTF, and release date | IMS version | Applicable environments | IMS Tools |
|---|---|---|---|---|
| IMS 15.5 release overview IMS uses a continuous delivery model to enhance the most recent in-service version of IMS. Instead of performing a full installation of IMS, you can migrate to IMS 15.5 from prior IMS 15.x releases by applying APAR PH59051. After the migration, output locations, including the output of the messages, commands, and log records that reflect IMS versions, are updated to 15.5. |
