Database range table example

An installation wants all the alias index entries for UIDs and GIDs to reside on data set 2, all profile names beginning with “GRPA” through “GRPF” and “TEST1” through “TEST8” to reside on data set 2, all profile names beginning with “SYS1” to reside on data set 3, and all the remaining data to reside on data set 1. The following range table meets these criteria:
