Upgrading Viprion 9.6.1

 

big3dshim is used to for compatibility between the legacy version of the iQuery protocol that existed on v4 3DNS, and the current version of iQuery introduced in v9 and above. It is a "shim" that translates between the two versions of the protocol.

 

 

This solution helps reveal how big3dshim is used:

If you're replacing your big3d with a v10 big3d, you should do the same for big3dshim too.

 

 

As a best practice, make a backup of each binary before you replace it. But I would not expect any issues by updating to v10 versions of the big3d and big3dshim binaries though the rest of the system is v9.6. That sort of thing is common in GTM environments.

 

 

 

(Check out "man big3d" too, and note that there is a way to run the big3d agent without forking off big3dshim also, since big3dshim is only really used when you have v4 boxes around too.)
