thank you for reply.
I have tried all the versions of InstantClient available on the Oracle site
The last working version on Mojave was Omnis 8.1.7 with InstantClient12_2.
All versions of Omnis Studio higher than 8.1.7 did not work on either
Mojave or Catalina.
I get always the same error:
damora8.u_xcomp component couldn’t be loaded because the code fragment is missing.
