I've been offered the possibility of having access to a mainframe only for learning purposes.
To save power the mainframe is powered down sometimes.
Recently, when the IPL (Initial Program Load) is made, a message appears in Red color in the console terminal.
*22.50.35 STC00029 *IEF882E CSQ7MSTR CSQ7MSTR IS WAITING FOR A REPLY TO
* IEF238D
* IEF238D
I believe that these messages showing in Red color are important messages, and this may be an error, but I don't know what this mean and how to solve this problem.
Thank you,
Roger
