Specify the TSSRNAME

When extracting or updating the installation data for the active user or another user, follow these directions:

If updating the installation data for an ACID other than the current ACID, place the ACID name in the TSSRNAME field, left justified
If updating the current ACID, you may place spaces (x'40') in the TSSRNAME field; optionally, the current ACID name can be placed in TSSRNAME
If a userid is passed in TSSRNAME instead of blanks, then an I/O to the security file will occur

To extract/update data from another user, the current ACID must be cross‑authorized for that ACID.
