Hi

The single instance does use same ORACLE_HOME. My doubt is however why the
single instance failed when RAC was still up and running? What can cause
LMON process terminated with error?

Cheers

Does your "single instance" use the same ORACLE_HOME as that of RAC?
Then the software is RAC-aware, communicates with clusterware etc. You
may use non-RAC home. On unix it is simple - just make a copy of
ORACLE_HOME, change the environment (ORACLE_HOME and dependants) and
relink oracle executable
$ export ORACLE_HOME=new_oracle_home # don't forget other environment
variables
$ cd $ORACLE_HOME/rdbms/lib
$ make -f ins_rdbms.mk ioracle rac_off
