Follow up. After lots of hours around this i got a fix: 1) Deinstalled Java 2) Downloaded the R Source 3) Configured ". oraenv" 4) Made sure the libsqora.so.11.1 was on the LD_LIBRARY_PATH 5) compiled from the source with the standard ./configure and make make install After this RODBC started working again. I used the old libraries so this must have something to do with how R is compiled. Still i am able to replicate the problem again. If i reinstall JAVA (any version of sdk_1.6.0 - sun and otherwise) an then run alternatives --config java (select the proper) And then R CMD jreconf Then its all over again. RODBC starts complaining about links and quits with segmentation fault. I would like to know how to get past this, but at least now i can use RODBC with oracle again. If anyone has any ideas i would really love to hear them.
