Connection pyrfc module error #315

Closed dcantos1 closed 1 year ago

dcantos1 commented 1 year ago

*I have installed the recommended versions of the wheel, Cython among others to install the pyrfc, I have the SAP SDK seteao in the environment variable SAPNWRFC_HOME=/dbfs/FileStore/nwrfc/nwrfcsdk/ and I install the pyrfc following the steps that are detailed but When I try to use the Connection module, it does not find it and I have reinstalled it and sometimes it gives me the error that appears in the screenshots.

Environment

It installs fine sometimes and gives me this Connection error image

Setting SAPNWRFC_HOME env variable is enough for building pyrfc. For run-time (ie. from pyrfc import *) SAP NWRFC SDK libraries must be registered on Linux system, like described in "Linux" section here, or using LD_LIBRARY_PATH:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$SAPNWRFC_HOME/lib

If SAP NWRFC SDK not already registered for runtime, apply on of these methods and re-try.

Here another test, how to check if SAP NWRFC SDK binaries are registered on your system:

cd $SAPNWRFC_HOME/bin
sudo chmod a+x rfcexec
./rfcexec # should show something like:
  Error: Not all mandatory parameters specified
    Please start the program in the following way:
    rfcexec -t -a <program ID> -g <gateway host> -x <gateway service>
     -f <file with list of allowed commands> -s <allowed Sys ID>
  The options "-t" (trace), "-f" and "-s" are optional.

Hello, thank you very much for your comment. I wanted to let you know that it did help me, except for one thing: you made a mistake in the word 'library,' export LD_LIBRARY_PATH=$LD_LIBRRY_PATH:$SAPNWRFC_HOME/lib you missed the 'A.' That's why it wasn't working for me initially, but now everything is okay.
