Problem loading libR.so when setting ore.parallel = TRUE

User12619059-OracleMay 23 2016 — edited Jun 24 2016

We now have an Oracle12c 12.0.1.0 DB installation and all the ORE client/server stuff set up.

However, I'm running into a problem when I try to enable ore.parallel.  When I do not enable ore.parallel things seem to be working.

Here is a client-side R console trace showing the problem.  I've highlighted the error message in red and then show in blue that by turning off ore.parallel that the same command works.
