I Cooked a SYSRES!
But before we all start panicking, let me preface this by saying it was on my employers z/D&T (Development and Test) environment – not a client system. No mainframes were hurt (much) in the making of this blog post. So what happened? TLDR: It turns out the SYS1.NUCLEUS dataset can’t have extents allocated, it must…

Adding Users to RACF
RACF users can be made with the ADDUSER command. Because creating a user is a multiple step process with a lot of different RACF commands involved, creating a user via batch is common. RACF commands can be run in batch with the IKJEFT01 program, which allows you to execute TSO commands in batch. There are…

TSO Logon Procedures and RACF
SYS1.UADS is the default dataset listing users that are allowed to use TSO/E [1]. Most sites that have RACF or other security products installed use those products to maintain their TSO/E logon information [2]. For a first time installation of RACF, IBM provides a command called RACONVRT to move users from SYS1.UADS to the RACF…

Purging the JES spool in SDSF
Many mainframe beginners will be familiar with how to manually purge job outputs from the JES spool one by one – that is, accessing the job status log via SDSF;ST and placing a P against the job entry to be purged. But there are ways we can purge multiple jobs without having to manually enter…
