When I try to run Oracle Report
rwrun.sh from my Java program, I get this error message:
REP-0004: Warning: Unable to open user preference file.
Apparently it happened because the program can’t find or doesn’t have the privillege to access the prefs.ora file. You can find
prefs.ora in here:
So, to fix this error, we must make sure that the
prefs.ora is exist in your HOME_DIRECTORY, as for me it’s
/home/wks-401/. Yours may be vary. Now we can simply copy the file, or you can make symbolic link to it. I prefer the symbolic link.
ln -sv $ORACLE_HOME/tools/admin/prefs.ora /home/wks-401/
That’s it. This Oracle Report error message REP-0004: Warning: Unable to open user preference file. is never showed up again. 😀
