When Oracle under Linux is used, INSO filters are not available. With the default enterprise.init, this results in an error message during server startup, which can be ignored. This can be fixed by editing enterprise.init and changing INSOFilterEnabled to "false", but it would be nice if INSOFilterEnabled had an equivalent in config.vars, so I didn't have to manually edit my enterprise.init after every "ant make-init".
What version of Oracle are you using ? INSO filters have worked fine on Linux for quite some time (since at least 9.0.1, possibly 8.1.7 too).
INSO filters do work on Oracle 8.1.7 on Linux. There is a remote possibility that I messed up the test during my last rounf of cleanups: p4 filelog src/com/arsdigita/mimetypes/MimeTypeInitializer.java | grep vadim ... #7 change 32790 edit on 2003/06/24 by vadim@vadim-at-home (ktext) 'cosmetic cleanup ' ... #6 change 32763 edit on 2003/06/23 by vadim@el-vadimo (ktext) 'cosmetic cleanup ' ... #5 change 32761 edit on 2003/06/23 by vadim@el-vadimo (ktext) 'Replaced a reference to "ACS Ja' dev bash$
I use Oracle 9.2, and just forgot to set LD_LIBRARY_PATH and PATH correctly. Sorry for bothering you with this.
