Abstract: It is often difficult to maintain user account quotas when a system has several applications with various quota requirements. The complexity increases when the requirements vary with the application version. MASS_UAF was written to address this problem.

MASS_UAF accepts a file that describes the quota requirements and a file that lists the accounts to process and ensures that each account has quota levels that fit the description. The quota description file looks much like the MODPARAMS.DAT file that is input to the AUTOGEN utility. Each quota can be listed with a value and an optional prefix. Valid prefixes are MAX_, MIN_, and ADD_. MAX_ defines a maximum quota value, MIN_ defines a minimum quota value, and ADD_ defines a delta value. If no prefix is used the value is an absolute setting. The quota name must not be abbreviated and must match either the label used by the AUTHORIZE utility SHOW/FULL command or the qualifier to the ADD command. The account listing file is simply a list of usernames, one per line, without wildcards. Any changes to quota values are displayed on SYS$OUTPUT. Possible conflicts with existing SYSGEN parameters are displayed as informational messages.

A recommended method for maintaining the user quotas is to create a quota description file for each version of a product installed. A simple naming convention is to use the name of the VMSINSTAL kit with an extension of .QUOTAS. Keep a list of authorized users or be able to create a list easily, possibly by reporting holders of a rights ID. Then use these two files and the MASS_UAF program to make sure the valid users will have sufficient quotas.
