Getting ORA-28595: Extproc agent : Invalid DLL Path after upgrade from 11g to 12c database.
I did specify the path to shared library in $ORACLE_HOME/hs/admin/extproc.ora as follows:
SET EXTPROC_DLLS=/r01/esri/arcgis_sde/sdeexe100/lib/libst_shapelib.so
...but still getting this error Anything else needs to be done per db upgrade for the external procedures to run OK - I just specified like this in extproc.ora and put actual upgraded library in that path. Listener.ora and tnsnames.ora do not have any entries for this. Help ..
