Re: ORA-00481: LMON process terminated with error


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

LS Cheng:
I have a single instance development database located in node 2 of a 9i RAC database. (development purpose as well). Recently the non-rac database had an instance failure showing this error

error 481 detected in background process
ORA-00481: LMON process terminated with error
ksuitm: waiting for [5] seconds before killing DIAG

I understand that error should apply to a RAC database. I am not able to find out why the database failed. Any lights?
