z/OS code modules changelog

Monthly PTFs (Program Temporary Fixes) are available for Dynatrace z/OS components through cumulative monthly maintenance, which is recommended for all users.

To download the cumulative PTFs, JCL exists in the sample library that's created during the initial install (hilevel.LZDT72.SZDTSAMP). FTPMAINT and RFNMAINT facilitate downloads from a Dynatrace FTP server with RFNMAINT taking advantage of Receive from Network technology.

You can find additional information in the SMP/E install of OneAgent for z/OS topic.

If you're using RFNMAINT, please update your JCL with the hash contained in the RFNINSTL job in the aforementioned link.
