Hi all, I'm looking for some insight on an issue our team ran into from a PuTTY user.

This team was in the process of getting setup for VSAM service in Production and getting an error from this particular user ID (let's call him U000000).

We looked at what group U000000 was in, and granted that group ALTER access to the data set profile VSAMSVCT.** in RACF. However, U000000 still received the same error.

We checked u000000 OMVS and home directory, and nothing looked out of the ordinary.

Any advice? [img][/img]

Message FSUM5027 explains it somewhat ok.

see: www.ibm.com/docs/en/zos/2.3.0?topic=messages-fsum5027

Summary is that you need a profile in the RACF SURROGATE class instead of the data set class. And grant permission to the user.

If I am not wrong,

The su -s - VSAMSVCT
switches the current user to VSAMSVCT. How would granting access to a dataset profile make the current user a surrogate user to VSAMSVCT?

I think you have to follow the steps here to setup VSAMSCVT as surrogate ID to U000000.

We tried that yesterday afternoon. We added U000000's group profile (lets call it group ABC#123) to Class Surrogate of BPX.SRV.VSAMSVC* and gave them READ access.

We also added group ABC#123 ALTER access to dataset profile VSAMSVCT.**

A part of me wonders if this is a user error on behalf of the PuTTY user? Because we defined the correct SURROGAT profile (at least I think we did? lol)

This forum posting gave me a little more context into that thought - www.ibmmainframeforum.com/mainframe-security/topic10013.html

spit balling here,

Have you checked if VSAMSCVT has an OMVS segment?

re: "We looked at what group U000000 was in"

Please confirm that your site has list-of-groups checking enabled.

For problem determination, consider permitting the user directly rather than the group.
