====== [DOC] Summary of Dataguard creation ======
===== creation =====

  * create the db (i mean, the master one)
  * modify tnsnames.ora
<code sql>
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)
		)
	)
</code>
  * replace the orapw (as ORACLE)
<code sql>
/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
</code>
  * broadcast the orapw file (as root):
<code sql>
rsync -av /u01/app/oracle/product/11.2.0/db/dbs/orapwCIBERDB node2:/u01/app/oracle/product/11.2.0/db/dbs/orapwCIBERDB
</code>
  * enable archiving
<code sql>
shutdown immediate ;
startup mount;
alter database archivelog;
ALTER DATABASE FORCE LOGGING;
alter database open ;
</code>
  * create the stby redos:
<code SQL>
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 ;
</code>
  * change multiple params for data guard:
<code SQL>
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;
</code>
  * rman it
<code SQL>
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''";
}
</code>
  * restart in mount the DB
<code SQL>
shutdown immediate ;
startup mount ;
</code>
  * add the stby to oratab in node2:
<code SQL>
CIBERSTB:/u01/app/oracle/product/11.2.0/db:N
</code>
  * Transfer the backup to node2
  * modify the init.ora (take care with that):
<code SQL>
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
</code>
  * Startup de stby:
<code sql>
startup nomount pfile=/u02/backup/DIVASTB/CIBERDB/initCIBERSTB.ora
</code>
  * Copy the spfile to the correct location
<code sql>
cp /u02/backup/DIVASTB/CIBERDB/initCIBERSTB.ora /u01/app/oracle/product/11.2.0/db/dbs/initCIBERSTB.ora
</code>
  * Create spfile
<code sql>
Create spfile from pfile;
</code>
  * Rman in the STBY:
<code sql>
rman auxiliary / target sys/mongui01@CIBERDB
DUPLICATE TARGET DATABASE FOR STANDBY;
</code>
  * Query de stby status:
<code sql>
Select DATABASE_ROLE FROM V$DATABASE ;
</code>
  * Start the redo receiver:
<code sql>
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE disconnect from session;
</code>
  * Open the primary:
<code sql>
alter database open;
Alter system switch logfile;
</code>
  * Query the primary status (must be valid):
<code sql>
Select Status, Error from v$Archive_dest where dest_id=2;
</code>
  * Query the apply status on the stby:
<code sql>
SELECT PROCESS, STATUS, THREAD#, SEQUENCE#, BLOCK#, BLOCKS FROM V$MANAGED_STANDBY;
SELECT SEQUENCE#, APPLIED FROM V$ARCHIVED_LOG ORDER BY SEQUENCE# ;
</code>


===== switchover to standby =====
  * On the Primary:
<code sql>
Alter Database Commit to Switchover to Physical Standby with session Shutdown;
shutdown immediate ;
startup mount ;
</code>
  * Check the status of the db (the old primary):
<code sql>
Select Database_role from v$database;
</code>
  * And start the MRP process:
<code sql>
Alter Database Recover Managed Standby Database Disconnect;
</code>
  * On the STBY HOST (the new primary) stop the MRP:
<code sql>
Alter database Recover Managed Standby Database Cancel;
</code>
  * AND change the role:
<code sql>
Alter Database Commit to Switchover to PRIMARY with session Shutdown;
</code>
  * check it:
<code sql>
Select Database_role from v$Database;
</code>
 
 
QUERY FOR CONTROL_FILES TO ASSURE THE CORRECT ONE'S ARE WORKING!!!
 
  * Restart the new primary:
<code sql>
shutdown immediate ;
startup;
</code>
  * CHECK status
<code sql>
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# ;
</code>	


  * It's possible that you need to alter the control files, in that case, you must query asmcmd for the actual ones.
<code sql>
ALTER SYSTEM SET CONTROL_FILES='+DG_NODE2_DATA/ciberstb/controlfile/current.290.806237525' scope=spfile sid='*';	
</code>

  * Make the standby create by their own the datafiles:
<code sql>
ALTER SYSTEM SET standby_file_management=AUTO  scope=spfile sid='*' ;
</code>

===== Setting up DataGuard Broker =====
  * Query the status:
<code sql>
show parameter broker ;
</code>
  * Start it
<code sql>
alter system set dg_broker_start=true scope=both;
</code>
  * watch alert to see the startup process
  * start the CLI
<code sql>
dgmgrl 'sys/mongui01@CIBERDB'
</code>
  * create the configuration:
<code sql>
create configuration 'jhtesting' as primary database is 'CIBERDB' connect identifier is 'CIBERDB';
</code>
  * Add the standby:
<code sql>
add database 'CIBERSTB' as connect identifier is 'CIBERSTB' maintained as physical;
</code>
  * Review the the config:
<code sql>
show configuration;
</code>
  * Enable the config:
<code sql>
enable configuration;
</code>
  * Perform a swithover:
<code sql>
switchover to 'CIBERSTB';
show database verbose 'CIBERSTB' ;
</code>

===== From Physical Standby to Snapshot =====
In the Stby, of course:
<code sql>
Alter database Recover Managed Standby Database Cancel;
</code>
Ensure that the database is mounted, but not open.
<code sql>
ALTER DATABASE CONVERT TO SNAPSHOT STANDBY;
</code>

===== From Snapshot to Physical Standby =====




====== Status Querys ======

===== ROLE of the connected DB =====
<code sql>Select Database_role from v$database;</code>
===== Status of the REDO shipping to STBY  =====
Maybe there are more than 1 stby database, so ''dest_id=X'' can be from 2 to "n":
<code sql>Select Status, Error from v$Archive_dest where dest_id=2;</code>

===== Determine the most recently archived redo log file =====
<code sql>
SELECT MAX(SEQUENCE#), THREAD# FROM V$ARCHIVED_LOG GROUP BY THREAD#;
</code>


===== List of archived_log ordered =====
<code sql>
SELECT SEQUENCE#, APPLIED FROM V$ARCHIVED_LOG ORDER BY SEQUENCE# ;
</code>
===== Determine the most recently archived redo log file at each redo transport destination =====
<code sql>
COL DESTINATION FORMAT A30 ;
SELECT DESTINATION, STATUS, ARCHIVED_THREAD#, ARCHIVED_SEQ# -
FROM V$ARCHIVE_DEST_STATUS -
WHERE STATUS <> 'DEFERRED' AND STATUS <> 'INACTIVE';
</code>
===== DataGuard STATS =====
on the slave
<code sql>
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$DATAGUARD_STATS ;
</code>
===== DataGuard LOG =====
on any node
<code sql>
COL FACILITY FORMAT A40;
COL SEVERITY FORMAT A30;
COL MESSAGE FORMAT A120;
SELECT * FROM V$DATAGUARD_STATUS ;
</code>


===== Standby Apply process status =====
<code sql>
COL PID format A10;
COL CLIENT_PID FORMAT A10 ;
COL CLIENT_DBID  FORMAT A12 ;
COL GROUP# FORMAT A12 ;
select * from V$MANAGED_STANDBY ;
</code>

===== Log History =====
<code sql>
SELECT THREAD#, SEQUENCE#, first_time, FIRST_CHANGE#, NEXT_CHANGE# FROM V$LOG_HISTORY;
