06449, 0000, "The list IO or the sysvendor is not installed."
*Cause: ORACLE tries to use the sysvendor interface (INIT.ORA parameter
use_sysvendor=true) but the UNIX kernel does not have the ORACLE
sysvendor interface linked in.
*Action: Set use_sysvendor=false in INIT.ORA, if you don't want to use
this interface or link the UNIX kernel with this interface so
that ORACLE can use it.
