Refresh tech lib information from disk

Yaosan

I'm trying to update the tech lib for opened cellviews but I couldn't find an easy way to do that. Say my opened cellview has no tech lib information and is attached to "cdsDefTechLib" by default. I updated the data.dm file from command line via p4 sync and now I want the opened cellview to use the proper tech lib defined in the updated data.dm file. How can I do this without restarting Cadence?

I tried techBindTechFile, techSetTechLibName etc. but all of them requires the data.dm file to be writable (the file is not writable for protection since it's revision controlled). Is there a way to refresh library properties directly from disk? Thanks!
