TYPERUN keyword
When the Recovery utility performs a simulated recovery, it reads all input data sets (logs, change accumulations, and image copies), but it does not write the output databases, indexes, and indirect list data sets (ILDSs); they are treated as DD DUMMY).
In a simulated recovery, the Recovery utility always uses AUTH(N). It does not access registered databases for authorization. You can request simulation for the full recovery, single-phase method. The two-phase method, which is specified with the RESTORE(Y) keyword, and the roll-forward method are not supported.
The BLDINDEX(Y) keyword is not ignored; although the index rebuild process is not performed, the rebuild process is simulated. However, if the index build process is required to perform a hierarchical scan of the target database, the rebuild process cannot be simulated. For example, a hierarchical scan is required if the index was built with a concatenated key or if a single partition of a HALDB is being recovered.
The BLDILDS(Y) or BLDILDS(R) keyword is not ignored; although the ILDS rebuild process is not performed, the rebuild process is simulated.
