There are far more efficient ways to do that.

  1. Move tables you want shared into a separate Namespace with separate Code/Data databases.
  2. Map your data and code into original namespace.
  3. Verify that it all works as expected. So far it should work as before.
  4. Create a mirroring configuration.
  5. Add 2 created databases to the mirror configuration.
  6. Add second server as a DR mirror.
  7. Move databases to a DR mirror and mount them there.
  8. (Optional) Create a namespace with 2 mirrored databases.
  9. Add desired mappings on a second system.

Just installed  Webterminal 4.8 on Cache for UNIX (SUSE Linux Enterprise Server for x86-64) 2015.2.1 (Build 705U) Mon Aug 31 2015 16:58:02 EDT [HealthShare Modules:Core:14.01.7952 + Linkage Engine:14.0.7952] and it seems to work.

Do you see /terminal web app in SMP? If it's not a production system try to give %ALL role to check if it helps.
