Issue/Introduction

We have a disaster recovery system where the security file is a new file that only has the MSCA acid. Is there a way to issue TSS commands to add a TSO segment to the MSCA acid without signing on the MSCA?

Environment

Release : 16.0

Resolution

You can do the following to add a TSO segment to the MSCA without signing on the MSCA:

1) From the console, issue:

F TSS,TSS

2) There should be a prompt: 

nnnn TSS9273A ENTER TSS COMMAND PASSWORD/PASSPHRASE

3) Reply with the MSCA password. For example: nnnn,pppppppp

Normally, the previous password for the MSCA needs to be specified here, but since this is a new security file and the MSCA does not yet have a previous password, the current password (from the SCA= specified in the MAINTIN in the TSSMAINS job) can be used.

4) If the password is accepted, the following prompt should appear:

nnnn TSS9272A ENTER <TSS COMMAND> OR <END>

5) Reply with the following TSS command:

nnnn,TSS ADD(msca) TSOLPROC(procname)

6) There should be another TSS9272A prompt. Reply with:

nnnn,TSS ADD(msca) TSOPROC(procname)

7) Reply to the next TSS9272A with:

nnnn,TSS LIST(msca) DATA(TSO)

and confirm it has TSOLPROC=procname

8) To exit this, reply to the next TSS9272A with:

nnnn,END
