Hi,We tried to run the Autosys 12.1 upgrade installer(AIX) to check for any unexpected errors. We got below error while running the installer on shadow server. We have a dual event server mode where Autosys and database is hosted on same servers .i.e. piaudb01 and piaudb02. EEM is also hosted on server piaudb01. We got the error while running installer on shadow server piaudb02. We have the same setup in UAT and we were able to upgrade to 12.1 successfully but in prod, we have run into this issue. We raised a case with Aptasolution and had a webex session with engineer from broadcom. He suggested to turn to NATIVE securty and then run the installer. It can be turned back to EEM security after the upgrade. We are wondering if turning to Native security and then turning back to EEM security would cause any issue afterwards.
