Hi guys,
I´m looking for a solution....
I have a Zos 2.5, running in a Hercules development environment, I'm trying
to put Zosmf on the air, but I get the message "Type=Illegal instruction
vmState=0x00000000J9Generic_Signal_Number=00000048 Signal_Number=00000004
Error_Value=00000000" I've tried using Java 8, Java 11, Java 17, and the
result is always the same. Could someone help me?
