Hi Krishna. The way to get it from SWDC:
Installations and Upgrades - H" SAP In-Memory (SAP HANA )" SAP HANA Add-ons" SAP HANA CONTENT TOOLS" SAP HANA CONTENT TOOLS 1.0
Inside the Content Tools ZIP archive you will find a file HCOHBAAFEXPLORER.tgz
Once this is installed, still your BASIS will need to do some magic to open ports and your HANA user will need at least a sap.hba.explorer.roles::Business, better yet sap.hba.explorer.roles::Developer role.
Here, admin guide comes very handy...
Cheers, Dmitry
