Cause

Wrong lsnodes in $DB_HOME

Solution

In this example:

GRID_HOME=/ocw/grid
DB_HOME=/oracle/11.2/db


The solution is to create the following symbolic link:

$ export GRID_HOME=/ocw/grid
$ export DB_HOME=oracle/11.2/db

$ cd $DB_HOME/bin
$ mv lsnodes lsnodes.old
$ ln -s $GRID_HOME/bin/olsnodes $DB_HOME/bin/lsnodes
$ ln -s $GRID_HOME/bin/olsnodes.bin $DB_HOME/bin/lsnodes.bin

$ cd $DB_HOME/oui/bin
$ mv lsnodes lsnodes.old
$ ln -s $GRID_HOME/bin/olsnodes $DB_HOME/oui/bin/lsnodes
$ ln -s $GRID_HOME/bin/olsnodes.bin $DB_HOME/oui/bin/lsnodes.bin
