Mainframe Prod Support at MNC (Am I cooked)?
I got a mainframe production support role at a reputed MNC.
My manager asked me to learn COBOL first..the tech stack will most likely be COBOL, JCL, CICS, DB2, VSAM.
Is this basic or if I can master all of the mentioned stuff I can shine in this field? I'm thinking of a career in mainframe, want to switch to mainframe dev, can you tell me what shld I learn to become a mainframe dev? What roles are popular in mainframe space??
