Back in June 2023 we published the following Support Tip that contained maintenance which we recommend customers install prior to upgrading to the ZMF 8.3 release:

 Support Tip: Recommended maintenance for customers running or upgrading to ChangeMan ZMF 8.3  

Since then a couple of further, potentially troublesome issues have also been identified for which hotfixes have been produced. The first is:

ZMF8.3.0.022/OCTCR46A325001 ‘CMN8856I - Package is promote locked.’ approving unplanned package 

For customers that use ZMF instances configured with an ALL environment type, i.e. those with ‘ChangeMan ZMF environment’ = ‘A’ specified in A.G.1 Part 1 of 8/ISPF panel CMNGGP01, we also recommend installing the fix for the following issue:

ZMF8.3.0.021/OCTCR46A325003 Variable &PRSNOD is blank in ChangeMan ZMF 8.3 'ALL' task 

The same notes, caveats, etc., as last time apply to the above recommendations. Namely:

a. All of the issues listed above, and their associated hotfixes, apply to the ZMF 8.3 release ONLY. These hotfixes must not be requested or applied to anything other than ZMF 8.3 subsystems.
b. Other known issues and further hotfixes do exist for the ZMF 8.3 release. However, those listed above are the ones assessed at time of publication of this Support Tip (i.e. 9th August 2023) as being particularly pervasive or troublesome if they were to be missed during upgrade testing.
c. Further Support Tips may be published in future should additional problems/fixes in the ZMF 8.3 release be assessed as being equally potentially problematic.
d. To request any of the hotfixes listed above please open a new case, one per hotfix, asking that the hotfix be supplied.
e. Similarly, should you hit any other issues during your ZMF 8.3 testing or upgrade then, again, please open a new case and we will be happy to assist.
