The VSS2OPTIMIZE option, when set to TRUE, is an explicit request for an existing structure (or structures) that uses the default blocking attributes of DASDL to be automatically reorganized for VSS-2 optimization. A setting of FALSE merely serves as notice to ignore an existing structure (or structures) that is not optimized.
A setting of FALSE cannot be used to “unoptimize” a structure.
VSS-2 optimized structures are aligned on block boundaries that are multiples of 60 words. Placing VSS-2 optimized structures on 180-byte aligned disks does not impact performance.
New structures, whether created as part of new databases or added to existing databases, are by default automatically optimized for VSS-2 if they allow DASDL to supply the blocking specifications. Specifying this option for these new structures serves as documentation only.
