AWS: ALTER SYSTEM and Managing SYS Objects in RDS

I’m very often managing services over EC2 and there are a few actions clients are often getting some issues to perform in RDS. So I decided to list here 5 of them:

Kill sessions:

begin
rdsadmin.rdsadmin_util.kill(
sid => &sid,
serial => &serial,
method => 'IMMEDIATE');
end;
/

Flush shared_pool or buffer_cache:

exec rdsadmin.rdsadmin_util.flush_shared_pool;
exec rdsadmin.rdsadmin_util.flush_buffer_cache;

Grant Privileges to SYS Objects

# Grant

begin
    rdsadmin.rdsadmin_util.grant_sys_object(
        p_obj_name  => 'V_$SESSION',
        p_grantee   => 'GREPORA',
        p_privilege => 'SELECT');
end;
/

# Grant with Grant Option

begin
    rdsadmin.rdsadmin_util.grant_sys_object(
        p_obj_name     => 'V_$SESSION',
        p_grantee      => 'GREPORA',
        p_privilege    => 'SELECT',
        p_grant_option => true);
end;
/

# Revoke

begin
    rdsadmin.rdsadmin_util.revoke_sys_object(
        p_obj_name  => 'V_$SESSION',
        p_revokee   => 'GREPORA',
        p_privilege => 'SELECT');
end;
/

Hope it Helps!
