Rebuild Standby database through rman restore after open it

1. remove archivelogs from default archivelog location

2. make rman backup files accessible to standby database

3. make rman know backup files
sqlplus> shutdown immediate;
sqlplus> startup mount;

rman target /
rman> catalog start with 'file location directory';

4. restore database
rman > run {
sql 'alter session set optimizer_mode=RULE';
sql 'ALTER SESSION SET NLS_DATE_FORMAT="DD-MON-YYYY HH24:MI:SS"';
ALLOCATE CHANNEL d1 DEVICE TYPE DISK FORMAT 'file location directory\DBFULL_%d_%U.bkp';
restore database from TAG "backup tag"   ;
RELEASE CHANNEL d1;
}

5. recover database
5.1 use controlfile before open database
rman target /
rman> recover database until sequence ?????;

5.2 use controlfile after open database
rman target /
rman> list incarnation;
rman> reset database to incarnation 1; ( previous number)
rman> recover database unitl seequnece ????;

5.3 test standby database
sqlplus / as sysdba
sqlplus> alter database open;
