The Directory Rebuild utility provides a means to rebuild the database directory for all 
defined CDS copies. 

The stand-alone Directory Rebuild utility: 

• runs under the control of the SLUADMIN utilities program 
• may be run while the CDS-related HSCs are STOPped 
• must be run using all CDS copies as input. 

The major purpose of the Directory Rebuild utility is to repair a corrupted CDS database 
directory when the HSC is not active. Normally, the HSC corrects errors automatically. 

The utility performs the following processing to rebuild the database directory: 

• opens the control data sets specified by the SLSCNTL, SLSCNTL2, and SLSSTBY 

DD statements 

• locates invalid pointers, directory entries, and recovery data 

• rewrites corrected blocks to all CDS copies.
