RO93797 is a change to module TIRLILOD. To pick up this fix, relink the DLL programs that call the Gen compatibility programs. This PTF is not required to fix this problem but since application programs must be relinked, then it would make sense to apply this PTF to relink all DLL and Compatibility components at the same time. As a suggestion, evaluate the time and resources necessary to assess the affected programs and when the installs can be done.
