The logonid TSORGN and TSOSIZE are defined as follow:
Indicates a user's default TSO region size (up to 2,147,483,648K), which is an MVS region size in kilobytes, if no size is specified at logon time. Zero
indicates no default TSO region size was specified. (Four-byte binary field)
Specifies a user's maximum TSO region size (up to 2,147,483,648K), which is an MVS region size in kilobytes, unless LGN-SIZE is specified for that user.
Zero indicates no maximum TSO region size was specified. (Four-byte binary field)
The TSO-SIZE will limit the user's TSO region size. The TSORGN is the default TSO region size. If the default TSORGN specified size exceeds the TSOSIZE the
following will occur:
If the TSORGN size take effect because the user does not have the ability to modify the region size at logon(LGN-SIZE|NOLGN-SIZE) or if the user has the
ability to specify region size at logon time and there is no value is specified the logon will fail with the following messages:
ACF82931 ACF2, LOGON ATTEMPT FAILED. SEE MESSAGE MANUAL FOR POSSIBLE CAUSES
ACF82904 ACF2, SESSION TERMINATED.
- If the TSO user tries to specify a region size at logon that exceeds the TSO-SIZE they will receive the ACF82929 message:
ACF82919 ACF2, HIGHLIGHTED FIELDS BELOW ARE INVALID, REENTER PARAMETERS
