Hi Jim,
We are supporting the SDE Command Line tools at 10.2.x. Starting at 10.3, the command line tools were not released. You can use the 10.2.2 command line tools and run the SDEGDBREPAIR, if needed, against your 10.2.2 geodatabase.
The SDEGDBREPAIR tools have been ported to a Geoprocessing Tool in ArcToolbox --> Data Management --> Geodatabase Administration toolbox.
Here is some more information on the ArcGIS 10.3 GP tools:

Hope this help....
