Optional customization

MFA can have 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 data set. The allocation of the user profile data set is done in the sample REXX exec hlq.MFA.EXEC(IVPINIT1) and should be customized to adhere to the installation's standards.

ISPF user profile allocation is performed as follows:

• DD statement ISPPROF is allocated to a temporary data set. If a MFA ISPF profile data set named userid.TAUZCISP.PROFILE already exists for the TSO user, the content of this ISPF profile is copied using IEBGENER to a temporary data set allocated under the ISPPROF DD statement.
• When the ISPF session terminates, control returns to REXX exec MFAREXX and the temporary ISPF profile is copied back to MFA profile data set userid.TAUZCISP.PROFILE.
• The temporary ISPF profile data set is deleted in REXX exec IVPTERM1.

  Micro Focus recommends that you allocate the temporary ISPF profile data set to an SMS managed temporary data set pool, which is automatically deleted according to the installation's standards. In this case, the deletion of the temporary ISPF profile data set in the REXX MFAREXX can be omitted.
