When installing just Database Organizer for IMS and no other IMS Tools, do you still need to run the following installation tasks:
IMT03ALU - Allocate product USS Datasets
IMT06MKD - Allocate product USS Directories
IMT15CSU - Customize SMP/E CSI for USS
You only need to execute the IMT03ALU, IMT06MKD and IMT15CSU installation jobs if a product feature requires a zFS file system.
Currently the only product feature in the IMS Tools that requires a z/FS file system is Conditional Reorg.
As Conditional Reorg is a component of Database Organizer, then the IMT03ALU, IMT06MKD and IMT15CSU install jobs must be executed when installing Database Organizer. This is required even if you do not plan to use Conditional Reorg.
