Oracle - MUST_RENAME_THIS_LOGFILE in logfile name

Question

I'm creating a data guard using hot backup from the primary server. In my restore I've used the following commands to restore:

run{
set newname for database to '+DADOS';
restore database;
switch datafile all;
switch tempfile all;
recover database;
}

After successful restore and recovery my redo logfile names has the name below:

select member from v$logfile;

+DADOS/MUST_RENAME_THIS_LOGFILE_1.4294967295.4294967295
+FRA/MOOTDB/ONLINELOG/group_1.287.1040583755
+DADOS/MUST_RENAME_THIS_LOGFILE_2.4294967295.4294967295
+DADOS/MUST_RENAME_THIS_LOGFILE_3.4294967295.4294967295
+FRA/MOOTDB/ONLINELOG/group_3.259.1036639239
+DADOS/MUST_RENAME_THIS_LOGFILE_4.4294967295.4294967295
+FRA/MOOTDB/ONLINELOG/group_2.288.1040583761
+DADOS/MUST_RENAME_THIS_LOGFILE_5.4294967295.4294967295
+FRA/MOOTDB/ONLINELOG/group_5.295.1042634101
+DADOS/MUST_RENAME_THIS_LOGFILE_6.4294967295.4294967295
+FRA/MOOTDB/ONLINELOG/group_6.297.1042634113

Why they have the "MUST_RENAME_THIS_LOGFILE_"? isn't automatic?

In my standby I'm using the db_log_file_name_convert and log_file_name_convert

log_file_name_convert = +DATA, +DADOS
db_file_name_convert = +DATA, +DADOS

Other issue is that some tempfiles come just with the DG name (see last line below).

select name from v$datafile union all select name from v$tempfile;

Answer 1

Restore + recovery from backup does not use online redo logs. Your redo logs were just named something, but those files do not exist yet. A physical standby database also does not use online redo logs (it uses standby redo logs).

The redo log groups will be automatically cleared (rename according to OMF + create the file) whenever they are needed the first time. Like when you actually open the database in READ WRITE mode after converting the physical standby into a primary database or snapshot standby or logical standby.

+FRA/MOOTDB/ONLINELOG/group_1.287.1040583755 is also incorrect. At this point that file does not exist and the location of that file, once cleared, will be +FRA/MOOTSTB/ONLINELOG/... as the db_unique_name on the standby site is MOOTSTB. (Assuming you have an FRA diskgroup there.)

With the db_create_file_dest, db_create_online_log_dest_N, db_recovery_file_dest parameters set properly, you can simply clear the logfile groups manually (what would be done automatically anyway when required), so they will be named and placed correctly:

alter database clear logfile group 1;
alter database clear logfile group 2;
alter database clear logfile group 3;
alter database clear logfile group 4;
alter database clear logfile group 5;
alter database clear logfile group 6;

The tempfile named +DADOS is also not a problem. A physical standby in mount stage does not require a tempfile. The tempfile will be automatically renamed and created once the database is opened.
