Executing alter system enable restricted session on RAC nodes

Question

alter system enable restricted session command enables restricted mode only on the node on which it runs. I need that all nodes entering this node after executing this statement.
Please help.

Answer 1

Something like this using ssh and ksh:
export db_name=<your database name as appears in crs_stat>
srvctl status database -d ${db_name} | while read a inst b c d e node
do
ssh -f $node "print $inst | . oraenv; print 'alter system enable restricted session;' | sqlplus / as sysdba"
done
or you using dbms_job (old but easer to tie to instance than dbms_scheduler):
declare
job binary_integer;
begin
for i in (select inst_id from gv$instance)
loop
dbms_job.submit (
job=>job,
what=> 'begin execute immediate ''alter system enable restricted session''; end;',
instance=>i.inst_id
commit;
end loop;
end;
