• create the db (i mean, the master one)
• modify tnsnames.ora

CIBERDB =
	(DESCRIPTION =
		(ADDRESS_LIST =
		  (ADDRESS = (PROTOCOL = TCP)(HOST = node1-vip)(PORT = 1521))
		)
		(CONNECT_DATA =
		  (SERVICE_NAME = CIBERDB)
		)
	)
 
CIBERSTB =
	(DESCRIPTION =
		(ADDRESS_LIST =
		  (ADDRESS = (PROTOCOL = TCP)(HOST = node2-vip)(PORT = 1521))
		)
		(CONNECT_DATA =
		  (SERVICE_NAME = CIBERSTB)
		)
	)

• replace the orapw (as ORACLE)

/u01/app/11.2.0/grid/bin/orapwd file=/home/oracle/orapwCIBERDB password="mongui01" entries=1
mv -fv /u01/app/oracle/product/11.2.0/db/dbs/orapwCIBERDB /u01/app/oracle/product/11.2.0/db/dbs/orapwCIBERDB.old
cp -pfv /home/oracle/orapwCIBERDB /u01/app/oracle/product/11.2.0/db/dbs/orapwCIBERDB

• broadcast the orapw file (as root):

rsync -av /u01/app/oracle/product/11.2.0/db/dbs/orapwCIBERDB node2:/u01/app/oracle/product/11.2.0/db/dbs/orapwCIBERDB

• enable archiving

shutdown IMMEDIATE ;
startup mount;
ALTER DATABASE archivelog;
ALTER DATABASE FORCE LOGGING;
ALTER DATABASE OPEN ;

• create the stby redos:

ALTER DATABASE ADD STANDBY LOGFILE ('+DG_NODE1_FRA/CIBERDB/stby01.rdo') SIZE 52428800 ;
ALTER DATABASE ADD STANDBY LOGFILE ('+DG_NODE1_FRA/CIBERDB/stby02.rdo') SIZE 52428800 ;
ALTER DATABASE ADD STANDBY LOGFILE ('+DG_NODE1_FRA/CIBERDB/stby03.rdo') SIZE 52428800 ;
ALTER DATABASE ADD STANDBY LOGFILE ('+DG_NODE1_FRA/CIBERDB/stby04.rdo') SIZE 52428800 ;

• change multiple params for data guard:

ALTER SYSTEM SET remote_login_passwordfile = SHARED scope=spfile;
ALTER SYSTEM SET LOG_ARCHIVE_CONFIG='DG_CONFIG=(CIBERDB,CIBERSTB)' scope=spfile  sid='*';
ALTER SYSTEM SET log_archive_dest_1='LOCATION=USE_DB_RECOVERY_FILE_DEST VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=CIBERDB' scope=spfile  sid='*';
ALTER SYSTEM SET log_archive_dest_2='SERVICE=CIBERSTB ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=CIBERSTB REOPEN=30' scope=spfile  sid='*';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_1=ENABLE scope=spfile  sid='*';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=ENABLE scope=spfile  sid='*';
ALTER system SET FAL_SERVER=CIBERSTB Scope=BOTH;
ALTER system SET FAL_CLIENT=CIBERDB SCOPE=BOTH;
ALTER SYSTEM  SET db_file_name_convert='+DG_NODE2_DATA/ciberstb/','+DG_NODE1_DATA/CIBERDB/','ciberstb','ciberdb','CIBERSTB','CIBERDB' scope=spfile ;
ALTER SYSTEM  SET log_file_name_convert='+DG_NODE2_DATA/ciberstb/','+DG_NODE1_DATA/CIBERDB/','+DG_NODE2_FRA/ciberstb/','+DG_NODE1_FRA/CIBERDB/','ciberstb','ciberdb','CIBERSTB','CIBERDB' scope=spfile;

• rman it

rman target /
run {
	ALLOCATE CHANNEL ch1 DEVICE TYPE DISK MAXPIECESIZE = 16G;
	crosscheck archivelog ALL;
	DELETE force noprompt expired archivelog ALL;
	backup FULL AS backupset filesperset 64 
	DATABASE format '/u02/backup/DIVAPRO/CIBERDB/Dades_%d_%T_%U'
	plus archivelog format '/u02/backup/DIVAPRO/CIBERDB/Arch_%d_%T_%U';
	SQL "create pfile=''/u02/backup/DIVAPRO/CIBERDB/initCIBERDB.ora'' from spfile";
	SQL "alter database backup controlfile to trace as ''/u02/backup/DIVAPRO/CIBERDB/Ctl_CIBERDB_001.trc''";
}

• restart in mount the DB

shutdown IMMEDIATE ;
startup mount ;

• add the stby to oratab in node2:

CIBERSTB:/u01/app/oracle/product/11.2.0/db:N

• Transfer the backup to node2
• modify the init.ora (take care with that):

cd /u02/backup/DIVAPRO/CIBERDB
cat initCIBERDB.ora | egrep -v "^CIBERDB\.|db_file_name_convert|log_archive_dest_2|log_file_name_convert|fal_(client|server)" | sed 's,DG_NODE1,DG_NODE2,g' | sed 's,jhdg,ciberstb,g' > initCIBERSTB.ora
cat >> initCIBERSTB.ora <<EOF
*.db_create_file_dest='+DG_NODE2_DATA'
*.db_file_name_convert='+DG_NODE1_DATA/jhdg/','+DG_NODE2_DATA/ciberstb/','jhdg','ciberstb','CIBERDB','CIBERSTB'
*.db_unique_name='CIBERSTB'
*.db_recovery_file_dest='+DG_NODE2_FRA'
*.fal_client='CIBERSTB'
*.fal_server='CIBERDB'
*.log_archive_config='DG_CONFIG=(CIBERDB,CIBERSTB)'
*.log_archive_dest_1='LOCATION=USE_DB_RECOVERY_FILE_DEST VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=CIBERSTB'
*.log_file_name_convert='+DG_NODE1_DATA/CIBERDB/','+DG_NODE2_DATA/jhsbt/','+DG_NODE1_FRA/CIBERDB/','+DG_NODE2_FRA/ciberstb/','jhdg','ciberstb','CIBERDB','CIBERSTB'
*.log_archive_dest_2='service=CIBERDB ASYNC valid_for=(ONLINE_LOGFILE,PRIMARY_ROLE) db_unique_name=CIBERDB'
EOF

• Startup de stby:

startup nomount pfile=/u02/backup/DIVASTB/CIBERDB/initCIBERSTB.ora

• Copy the spfile to the correct location

cp /u02/backup/DIVASTB/CIBERDB/initCIBERSTB.ora /u01/app/oracle/product/11.2.0/db/dbs/initCIBERSTB.ora

• Create spfile

CREATE spfile FROM pfile;

• Rman in the STBY:

rman auxiliary / target sys/mongui01@CIBERDB
DUPLICATE TARGET DATABASE FOR STANDBY;

• Query de stby status:

SELECT DATABASE_ROLE FROM V$DATABASE ;

• Start the redo receiver:

ALTER DATABASE RECOVER MANAGED STANDBY DATABASE disconnect FROM SESSION;

• Open the primary:

ALTER DATABASE OPEN;
ALTER system switch logfile;

• Query the primary status (must be valid):

SELECT STATUS, Error FROM v$Archive_dest WHERE dest_id=2;

• Query the apply status on the stby:

SELECT PROCESS, STATUS, THREAD#, SEQUENCE#, BLOCK#, BLOCKS FROM V$MANAGED_STANDBY;
SELECT SEQUENCE#, APPLIED FROM V$ARCHIVED_LOG ORDER BY SEQUENCE# ;

• On the Primary:

ALTER DATABASE Commit TO Switchover TO Physical Standby WITH SESSION Shutdown;
shutdown IMMEDIATE ;
startup mount ;

• Check the status of the db (the old primary):

SELECT Database_role FROM v$database;

• And start the MRP process:

ALTER DATABASE Recover Managed Standby DATABASE Disconnect;

• On the STBY HOST (the new primary) stop the MRP:

ALTER DATABASE Recover Managed Standby DATABASE Cancel;

• AND change the role:

ALTER DATABASE Commit TO Switchover TO PRIMARY WITH SESSION Shutdown;

• check it:

SELECT Database_role FROM v$Database;

QUERY FOR CONTROL_FILES TO ASSURE THE CORRECT ONE'S ARE WORKING!!!

• Restart the new primary:

shutdown IMMEDIATE ;
startup;

• CHECK status

SELECT Database_role FROM v$Database;
SELECT STATUS, Error FROM v$Archive_dest WHERE dest_id=2;
SELECT PROCESS, STATUS, THREAD#, SEQUENCE#, BLOCK#, BLOCKS FROM V$MANAGED_STANDBY;
SELECT SEQUENCE#, APPLIED FROM V$ARCHIVED_LOG ORDER BY SEQUENCE# ;

• It's possible that you need to alter the control files, in that case, you must query asmcmd for the actual ones.

ALTER SYSTEM SET CONTROL_FILES='+DG_NODE2_DATA/ciberstb/controlfile/current.290.806237525' scope=spfile sid='*';	

• Make the standby create by their own the datafiles:

ALTER SYSTEM SET standby_file_management=AUTO  scope=spfile sid='*' ;

• Query the status:

SHOW parameter broker ;

• Start it

ALTER system SET dg_broker_start=TRUE scope=BOTH;

• watch alert to see the startup process
• start the CLI

dgmgrl 'sys/mongui01@CIBERDB'

• create the configuration:

CREATE configuration 'jhtesting' AS PRIMARY DATABASE IS 'CIBERDB' CONNECT identifier IS 'CIBERDB';

• Add the standby:

ADD DATABASE 'CIBERSTB' AS CONNECT identifier IS 'CIBERSTB' maintained AS physical;

• Review the the config:

SHOW configuration;

• Enable the config:

enable configuration;

• Perform a swithover:

switchover TO 'CIBERSTB';
SHOW DATABASE verbose 'CIBERSTB' ;

In the Stby, of course:

ALTER DATABASE Recover Managed Standby DATABASE Cancel;

Ensure that the database is mounted, but not open.

ALTER DATABASE CONVERT TO SNAPSHOT STANDBY;

SELECT Database_role FROM v$database;

Maybe there are more than 1 stby database, so dest_id=X can be from 2 to “n”:

SELECT STATUS, Error FROM v$Archive_dest WHERE dest_id=2;

SELECT MAX(SEQUENCE#), THREAD# FROM V$ARCHIVED_LOG GROUP BY THREAD#;

SELECT SEQUENCE#, APPLIED FROM V$ARCHIVED_LOG ORDER BY SEQUENCE# ;

COL DESTINATION FORMAT A30 ;
SELECT DESTINATION, STATUS, ARCHIVED_THREAD#, ARCHIVED_SEQ# -
FROM V$ARCHIVE_DEST_STATUS -
WHERE STATUS <> 'DEFERRED' AND STATUS <> 'INACTIVE';

on the slave

col SOURCE_DB_UNIQUE_NAME format a15
col unit format a30
col TIME_COMPUTED format a30
col DATUM_TIME format a30
col VALUE FORMAT A18;
SELECT * FROM V$DATAGUARD_STATS ;

on any node

COL FACILITY FORMAT A40;
COL SEVERITY FORMAT A30;
COL MESSAGE FORMAT A120;
SELECT * FROM V$DATAGUARD_STATUS ;

COL PID format A10;
COL CLIENT_PID FORMAT A10 ;
COL CLIENT_DBID  FORMAT A12 ;
COL GROUP# FORMAT A12 ;
SELECT * FROM V$MANAGED_STANDBY ;

SELECT THREAD#, SEQUENCE#, first_time, FIRST_CHANGE#, NEXT_CHANGE# FROM V$LOG_HISTORY;
