failing to load ROracle: unable to load shared object ROracle.so: libclntsh.so.11.1 No such file or directory

Question

So I can\'t load ROracle. I am indeed very new to this so any information is appreciated and any info regarding what further information to give would be helpful as well.

Answer 1

ORACLE_HOME should point to just one location. Shouldn't you set LD_LIBRARY_PATH_64 variable?

Answer 2

If you really really really want to do this within the R environment, you can load the specific library as follows:

dyn.load("/usr/lib/oracle/11.2/client64/lib/libclntsh.so.11.1")
library(ROracle)

Setting LD_LIBRARY_PATH from inside R

Answer 3

Set this in /etc/rstudio/rserver.conf

rsession-ld-library-
path=/usr/lib64/R/lib:/home/oracle/app/oracle/product/12.1.0/client_1/lib

Then restart Rserver

sudo rstudio-server stop
sudo rstudio-server start

This helped me.

Answer 4

set $LD_LIBARARY_PATH=$ORACLE_HOME/lib

Answer 5

I got same error while loading "library(ORE)"

  Error in dyn.load(file, DLLpath = DLLpath, ...) :
      unable to load shared object '/usr/lib64/R/library/ROracle/libs/ROracle.so':
      libclntsh.so.11.1: cannot open shared object file: No such file or directory
    Error: package 'OREdm' could not be loaded

Looks like the shared object ROracle.so is referring to libclntsh.so.11.1 instead of libclntsh.so.12.1

bash-4.1$ pwd
/usr/lib64/R/library
bash-4.1$ grep -irsh "libclntsh.so.11.1" *
Binary file ROracle/libs/ROracle.so matches

As a work around, I have created a symlink, so that libclntsh.so.12.1 can be referred as libclntsh.so.11.1.

$ cd /scratch/softwares/R/db_instant_client/instantclient_12_1

 ln -s libclntsh.so.12.1 libclntsh.so.11.1

After this step, I am able to load library(ORE) successfully.
