A BCS can be specified by either INFILE orINDATASET.If you are authorized to the RACF FACILITY class name ofSTGADMIN.IDC.DIAGN<strong>OS</strong>E.CATALOG, you are allowed to open a catalogwithout per<strong>for</strong>ming usual catalog security processing. If you are authorized tothis FACILITY class name, normal RACF checking is bypassed.

Because a VVDS must be referenced by itsvolume serial number and unit, use COMPAREDD to specify a VVDS. A BCScan be specified by either COMPAREDD or COMPAREDS. For diagnosis of aBCS, the compare parameters identify VVDS names (you can specify amaximum of 99 names). When diagnosing a VVDS, these parameters identifyappropriate BCS data sets.If COMPAREDS or COMPAREDD are specified <strong>for</strong> the catalog whose name isindicated by the VVDS entry, the catalog should have:vvA non-VSAM record corresponding to the NVR, or a cluster recordcorresponding with the data or index VVR.The same storage class, data class, and management class names in thecorresponding non-VSAM or cluster record.If you are authorized to the RACF FACILITY class name ofSTGADMIN.IDC.DIAGN<strong>OS</strong>E.VVDS, you are allowed to open a catalogwithout per<strong>for</strong>ming normal catalog security processing.
