Instructions on how to install ROracle for R on Windows.

Raw

Download binary from oracle: http://www.oracle.com/technetwork/database/database-technologies/r/roracle/downloads/index.html

The run the following command in r, substituting the file path:

setwd('xxxxx')   # set to path of download
install.packages('ROracle_1.1-11.zip', repos = NULL)

Then load the library and use the package - you may have to change XXXX to whatever is in your TNS Names:

library('ROracle')
drv <- dbDriver("Oracle")
# NOTE: never store passwords in a saved script!!
con <- dbConnect(drv, "USER GOES HERE", "PASSWORD GOES HERE", dbname='XXX')

test connection:

dbReadTable(con, 'DUAL')

Installing Oracle Client on my computer fixed this issue.

For anyone else having trouble installing ROracle, the installation instructions on CRAN are actually very good and the links appear to all be working at the time of posting this. http://cran.us.r-project.org/web/packages/ROracle/INSTALL

Chicago-Dave commented Feb 20, 2018

True, the CRAN instructions and error resolution page is quite extensive. Thanks for the link. However, I am experiencing the same issue and the error message I get does not match precisely any of those on the page.

"Error: package or namespace load failed for ‘ROracle’ in inDL(x, as.logical(local), as.logical(now), ...):
unable to load shared object '//SomeUniversity/HOME/R/win-library/3.4/ROracle/libs/x64/ROracle.dll':
LoadLibrary failure: The specified module could not be found."

The file is in the directory, compiled in x64 and running x64; Anyone know if the function 'inDL' is part of ROracle? DBI?

Your instructions are very clear and easy to follow. Thanks

adc91 commented Mar 18, 2018

@gmonteeiro just that you had to install it or did you need some extra configuration? Because it still does not work :(

siddhesh1991 commented Apr 27, 2018

ROracle is not working with new version 3.5.0. Do you know why ?

ofaakye commented May 3, 2018

@siddhesh1991 ROracle is not working for as well on the new R 3.5.0. Did you find any solutions?

tlorusso commented Jun 6, 2018

Same here. I've just installed R 3.5.0 - and i get an error when loading the package:

Error: package or namespace load failed for ‘ROracle’:
 package ‘ROracle’ was installed by an R version with different internals; it needs to be reinstalled for use with this R version

Has anyone found a solution to this?

siddhesh1991 commented Jun 20, 2018

R version 3.5.0 (2018-04-23) -- "Joy in Playing"

ROracle is not working with the new version of R, Can anyone help ?

turingDH commented Jun 25, 2018

We looked everywhere for a solution, to no avail...had to roll back to 3.4. Thanks Larry E 👎

Hello,

I had similar error. Here are few things that I have done to make it work successfully on windows X-64 machine.

Downloaded Oracle instant client and unzipped it (copy its path). Then added a new variable in the existing Path variable (under System Variables), paste this path here.
Uninstalled all R versions.
Reinstalled R (Version R-3.5.1)
Downloaded ROracle package (ROracle_1.3-1.zip) from https://www.oracle.com/technetwork/database/database-technologies/r/roracle/downloads/index.html . Save the downloaded zip file
Open RStudio (or whatever you use) and run the below:

install.packages("C:\\Users\\username\\Desktop\\Software\\R\\ROracle_1.3-1.zip")   
library("ROracle")

Then ROracle got installed correctly. Make sure you are installing the downloaded package from step-3

Let me know if it still doesn't work. Happy to help!

Hi @jssasan, when following your steps I get the following error:

Warning in install.packages : package ‘C:\Users\codrin_kruijne\Documents\ROracle\ROracle_1.3-1.zip’ is not available (for R version 3.5.1)

so I set the repos to NULL:

install.packages("C:\\Users\\codrin_kruijne\\Documents\\ROracle\\ROracle_1.3-1.zip", repos = NULL) Installing package into ‘C:/Users/codrin_kruijne/Documents/R/win-library/3.5’ (as ‘lib’ is unspecified) package ‘ROracle’ successfully unpacked and MD5 sums checked

but when I try to load it I get the following error:

library(ROracle) Loading required package: DBI Error: package or namespace load failed for ‘ROracle’: package ‘ROracle’ was installed by an R version with different internals; it needs to be reinstalled for use with this R version

so I downloaded RTools to recompile it from the source on CRAN:

install.packages("ROracle")

Installation of ROracle is a bit tricky.

Download ROracle package on your PC: https://www.oracle.com/database/technologies/roracle-downloads.html
Download the tar.gz package!
Access the INSTALL file on ROracle sub-directory and follow the instructions. The installation differs if you have or not Oracle installed on your machine.

Good instructions in: # https://medium.com/analytics-vidhya/how-to-install-roracle-on-windows-10-144b0b923dac

IMPORTANT

ROracle can't be directly installed on R4+

So, download ROracle package on your PC: https://www.oracle.com/database/technologies/roracle-downloads.html
Download the tar.gz package!

Install it on your RStudio with the following command:

install.packages('C:\Downloads\ROracle_1.3-2.tar.gz', repos = NULL, type="source")

Don't forget to correct the directory in which you've downloaded the file. This will recompile your package to version 4 of R.
