ERO Not Compatible With Reusable ASIDs
ChangeMan ZMF ERO calls Db2, which is not compatible with reusable ASIDs, so ERO is not compatible with reusable ASIDs.
If you use z/OS START command parameter REUSASID=YES to start a ZMF instance where ERO is licensed, ERO is disabled and does not appear in ZMF menus. The following message is displayed in SERPRINT:
CMN_302I CMNSTART ERO has been disabled: Server started with reusable ASID
To use ERO, restart the ZMF instance without the REUSASID=YES parameter in the START command.
