ISPF user profile

z/Server allows more than one user server per TSO user to be run in parallel. Each user server needs its own exclusive ISPF environment. This implies the allocation of an ISPF user profile dataset. The allocation of the user profile dataset is done in the sample REXX exec IVPINIT1 and should be customized to adhere to the installation's standards.

ISPF user profile allocation is done as follows:

• DD statement ISPPROF is allocated to a temporary dataset. If a z/Server ISPF profile dataset named userid.TAUZCISP.PROFILE already exists for the TSO user, the content of this ISPF profile is copied using IEBGENER to a temporary dataset allocated under the ISPPROF DD statement.
• ISPF is started and control is passed to REXX exec IVPINIT2.
• When the ISPF session terminates, control returns to REXX exec IVPINIT1, and the temporary ISPF profile is copied back to z/Server profile dataset userid.TAUZCISP.PROFILE.
• The temporary ISPF profile dataset is deleted.  

We recommend that you allocate the temporary ISPF profile dataset to an SMS managed temporary dataset pool, which is automatically deleted according to installations' standards. In that case, the deletion of the temporary ISPF profile dataset in the REXX IVPINIT1 can be omitted.
