We have a quite large (~180M records) Adabas file with some super-descriptors on it.
My question: is there any way - without making any changes on the file - to know that a specific super-descriptor contains only unique values (something like
ADAINV INVERT FILES SUPDE=super-field,UQ, TEST
(and RC = 0 if this is true
or ABEND if this verification fails). I suspect it is NOT possible, but I am NOT an expert in this area.
Many thanks in advance.
