Oracle Solution for Error ora-29704

ORA-29704: cannot specify ACTIVE_INSTANCE_COUNT in 8.1.5 or earlier release

What triggered the Error:

e ACTIVE_INSTANCE_COUNT parameter was specified when one of the instances in the cluster was running Oracle 8.1.5 or an earlier release.

What should we do to fix it:

start the instance without specifying the ACTIVE_INSTANCE_COUNT parameter. Or, upgrade all instances to Oracle 8.1.6 or later release and then specify the parameter.
