  Just be aware that these queries are queries controlfile and if they run too long can get in the road of the database as they hold controlfile locks. You'd better watch the view v$ dataguard_stats the day before and look at the GAL apply and transport.

  We are also a few scripts in our book - http://www.amazon.com/Oracle-Guard-Handbook-Osborne-ORACLE/dp/0071621113

• Cloning by rman on a different server with the directory structure different and different DBNAME in EBS 11i using quick Clone

  Hello

  We want only DB (not apps) cloning through PROD rman, step TEST EBS 11i using quick Clone without taking downtime of PROD (i.e. No. BKP COLD).

  Source and target are on different servers, different file structure and the different database name.

  Kindly let me know the detailed procedure?

  Kind regards

  RR

  
  

  You can use this simple method that I am.
  

  
  

  Take backup of production with rman:

  {

  overlap archivelog all;

  backup format compressed backupset database tag PROD_FULLBKP ' / u10/PROD1_L0_BKUP_20131125/PROD_DB_set%s_piece%p_%T_%U' filesperset 15;

  SQL 'alter database backup controlfile to trace. "

  SQL 'alter system switch logfile;

  SQL 'alter system switch logfile;

  SQL 'alter system switch logfile;

  overlap archivelog all;

  backup as compressed backupset archivelog all delete input PROD_ARCHBKP format tag ' / u10//PROD1_L0_BKUP_20131125/ARCH_PROD_set%s_piece%p_%T_%U' filesperset 20;

  backup format ' / u10/PROD1_L0_BKUP_20131125/PROD_ctl_%T_%U' current controlfile;

  }

  
  

  Move the backup on the test server:

  SCP /ftp

  Modify the pfile to the test server:

  Parameters such as:

  db_name

  control_files

  modify the pfile to match the location of the test server

  Add this parameter

  db_file_name_convert = ' / PROD_datafile_location/datafile ', ' / test_datafile_location / data ', ' / PROD_datafile_location/tempfile ', ' / test_datafile_location / data.

  log_file_name_convert = ' / PROD_redofile_location/ONLINELOG ', ' / test_redofile_location / data ".

  Start the DB:

  Start the db in nomount:

  startup nomount.

  Connecting to rman and start to restore:

  Auxiliary RMAN.

  RMAN > run

  {

  allocate auxiliary channel a1 device type disk;

  allocate auxiliary channels a2 device type disk;

  allocate auxiliary channel a3 device type disk;

  allocate auxiliary channel a4 device type disk;

  data duplicated in the PREPRODUCTION backup location ' / u10/PREPRODUCTION/oraR12/clone_backup/PROD1_L0_BKUP_20131125 ";

  }

  OR

  If you specify time/perform a recovery of time based, like below:

  RMAN > run

  {

  allocate auxiliary channel a1 device type disk;

  allocate auxiliary channels a2 device type disk;

  allocate auxiliary channel a3 device type disk;

  allocate auxiliary channel a4 device type disk;

  data duplicated in PREPRODUCTION backup location 'LOCATION_OF_BACKUP', until ' TO_DATE (7 July 2012 09:45 ',' DD/MM/YYYY HH24:MI:SS') ";

  }

• ESX server with 2 different storage array?

  Hello.

  I currently have my ESX servers connected to storage DS4700 and most berries.  Each ESX is double path via a switch which, in turn, allows me to see my DS4700.  My question is, can I i the area my ESX Server so that it can "see" my DS8300 and I would be able to assign LUNS of my ESX servers with no problems?  Both can coexist?  I think I should use for my DS4700 host bus adapters and host bus adapters that are dedicated to my DS8300?  A UNIX point, these 2 storage arrays do not 'communicate' the same way (for example, SDD and RDAC).

  Thank you.

  Steph

  SDD driver is for the multipath. VMware has its own multi-channel driver that is shipped with ESX server, you won't not any 3rd party multipathing software.

  In any case to be abel to see camps Bay you have no need to activate the software multpathing. It is intended only to provide a redundant path to any logical unit number hosted by a single table through several MS SPs/Ports.

  Area just for DS8300 ESX Server and a new analysis should see the new targets and when you present LUNS to your host definetion analyze again another you should see the DS8300 LUN.

  I hope this helps.

• Waiting for redo log file missing when restore main database using RMAN backup that was taken on the database physical standby

  Here's my question after tons of research and test without have the right solutions.

  Target:

  (1) I have a 12.1.0.2 database unique main enterprise 'testdb' as database instance running on the server "node1".

  (2) I created physical standby database "stbydb" on the server "node2".

  (3) DataGuard running on the mode of MaxAvailability (SYNC) with roll forward in real time 12 default c apply.

  (4) primary database has 3 groups of one-man redo. (/oraredo/testdb/redo01.log redo02.log redo03.log)

  (5) I've created 4 standby redo logfiles (/oraredo/testdb/stby01.log stby02.log stby03.log stby04.log)

  (6) I do RMAN backup (database and archivelog) on the site of relief only.

  (7) I want to use this backup for full restore of the database on the primary database.

  He is a DR test to simulate the scenario that has lost every primary & Eve total servers.

  Here is how to save, on the database pending:

  (1) performance 'alter database recover managed standby database Cancel' to ensure that compatible data files

  (2) RMAN > backup database;

  (3) RMAN > backup archivelog all;

  I got elements of backup and copied to primary db Server something like:

  /Home/Oracle/backupset/o1_mf_nnndf_TAG20151002T133329_c0xq099p_.BKP (data files)

  /Home/Oracle/backupset/o1_mf_ncsnf_TAG20151002T133329_c0xq0sgz_.BKP (spfile & controlfile)

  /Home/Oracle/backupset/o1_mf_annnn_TAG20151002T133357_c0xq15xf_.BKP (archivelogs)

  So here's how to restore, on the main site:

  I clean all the files (data files, controlfiles oder all gone).

  (1) restore spfile from pfile

  RMAN > startup nomount

  RMAN > restore spfile from pfile ' / home/oracle/pfile.txt' to ' / home/oracle/backupset/o1_mf_ncsnf_TAG20151002T133329_c0xq0sgz_.bkp';

  (2) modify pfile to convert to db primary content. pFile shows below

  *.audit_file_dest='/opt/Oracle/DB/admin/testdb/adump '

  * .audit_trail = "db".

  * full = '12.1.0.2.0'

  *.control_files='/oradata/testdb/control01.ctl','/orafra/testdb/control02.ctl'

  * .db_block_size = 8192

  * .db_domain = "

  * .db_recovery_file_dest_size = 10737418240

  * .db_unique_name = "testdb".

  *.diagnostic_dest='/opt/Oracle/DB '

  * .fal_server = "stbydb".

  * .log_archive_config = 'dg_config = (testdb, stbydb)'

  * .log_archive_dest_2 = "service = stbydb SYNC valid_for = (ONLINE_LOGFILE, PRIMARY_ROLE) db_unique_name = stbydb'"

  * .log_archive_dest_state_2 = 'ENABLE '.

  *.log_file_name_convert='/testdb/','/testdb /'

  * .memory_target = 1800 m

  * .open_cursors = 300

  * runoff = 300

  * .remote_login_passwordfile = "EXCLUSIVE."

  * .standby_file_management = "AUTO".

  * .undo_tablespace = "UNDOTBS1.

  (3) restart db with updated file pfile

  SQLPLUS > create spfile from pfile='/home/oracle/pfile.txt'

  SQLPLUS > the judgment

  SQLPLUS > startup nomount

  (4) restore controlfile

  RMAN > restore primary controlfile to ' / home/oracle/backupset/o1_mf_ncsnf_TAG20151002T133329_c0xq0sgz_.bkp';

  RMAN > change the editing of the database

  (5) all elements of backup catalog

  RMAN > catalog starts by ' / home/oracle/backupset / '.

  (6) restore and recover the database

  RMAN > restore database;

  RMAN > recover database until the SNA XXXXXX; (this YVERT is the maximum in archivelog backups that extends beyond the scn of the backup of the data file)

  (7) open resetlogs

  RMAN > alter database open resetlogs;

  Everything seems perfect, except one of the file log roll forward pending is not generated

  SQL > select * from v$ standby_log;

  ERROR:

  ORA-00308: cannot open archived log ' / oraredo/testdb/stby01.log'

  ORA-27037: unable to get file status

  Linux-x86_64 error: 2: no such file or directory

  Additional information: 3

  no selected line

  I intended to use the same backup to restore primary basic & helps record traffic and the downtime between them in the world of real output.

  So I have exactly the same steps (except STANDBY restore CONTROLFILE and not recover after database restore) to restore the database pending.

  And I got the same missing log file.

  The problem is:

  (1) complete alert.log filled with this error, not the concern here

  (2) now repeat it in real time apply won't work since the Party shall LGWR shows always "WAITING_FOR_LOG."

  (3) I can't delete and re-create this log file

  Then I tried several and found:

  The missing standby logfile was still 'ACTIVE' at present RMAN backup was made.

  For example, on db standby, under Group #4 (stby01.log) would be lost after the restoration.

  SQL > select GROUP #, SEQUENCE #, USE (s), the STATUS from v$ standby_log;

  GROUP # SEQUENCE # USED STATUS

  ---------- ---------- ---------- ----------

  4 19 ACTIVE 133632

  5 0 0 UNASSIGNED

  6 0 0 not ASSIGNED

  7 0 0 UNASSIGNED

  So until I take the backup, I tried on the primary database:

  SQL > alter system set log_archive_dest_state_2 = delay;

  This was the Group of standby_log side Eve #4 was released:

  SQL > select GROUP #, SEQUENCE #, USE (s), the STATUS from v$ standby_log;

  GROUP # SEQUENCE # USED STATUS

  ---------- ---------- ---------- ----------

  4 0 0 UNASSIGNED

  5 0 0 UNASSIGNED

  6 0 0 not ASSIGNED

  7 0 0 UNASSIGNED

  Then, the backup has been restored correctly without missing standby logfile.

  However, to change this primary database means break DataGuard protection when you perform the backup. It's not accept on the production environment.

  Finally, my real questions come:

  (1) what I do may not do on parameter change?

  (2) I know I can re-create the control file to redo before delete and then recreate after. Is there any simple/fast to avoid the standby logfile lost or recreate the lost one?

  I understand that there are a number of ways to circumvent this. Something to keep a copy of the log file waiting restoration progress and copy up one missing, etc, etc...

  And yes I always have done no real-time applies "to the aid of archived logfile" but is also not accept mode of protection of production.

  I just want proof that the design (which is displayed in a few oracle doc Doc ID 602299.1 is one of those) that backs up data backup works effectively and can be used to restore the two site. And it may be without spending more time to resume backups or put the load on the primary database to create the database before.

  Your idea is very much appreciated.

  Thank you!

  Hello

  1--> when I take via RMAN backup, RMAN does not redo log (ORL or SRL) file, so we cannot expect ORLs or SRL would be restored.

  2nd--> when we opened the ORL database should be deleted and created

  3rd--> Expecting, SRL should not be an issue.we should be able to do away with the fall.

  If you do, you can recreate the controlfile without waiting for redo log entry...

• DataGuard (activate a physical standby as a stand-alone database database)?

  Hi all

  Can I please ask advice on how it would activate a physical database ensures for 11.2.0.4?

  Note - I do not want to return the "standby" to watch again...

  Note 1 – I don't have (and don't use flashback technology to do this) - so I can't use a watch "snapshot"...

  Note 2 - the 'primary' current cannot be touched.

  Something like below?

  Repeat stop applies to pending

  SQL > alter database recover managed standby database cancel;

  Stop redo pending transaction logs.

  PRIMARY

  SQL > ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2 = DELAY;

  Activate and open the database physical sleep.

  Concerning

  It wouldn't affect Production (primary). It's just the steps of failover.

  The same applies to the role transition, but in a role transition, you must first pass at the primary level of Eve and the day before, you must run the digital switchover to make primary.

  You could refer to this https://docs.oracle.com/cd/E11882_01/server.112/e41134/role_management.htm#SBYDB4769 you would get to the difference of the steps for the passage and failover.

• DG 1 physical standby

  Hello

  11.2.0.1

  We have a DEV database which is also as critical as the PROD db since there are many strategic projects running on it.

  This DEV database has been configured with dataguard physical standby on the DR server.

  Well, that's what I read in the documents only as I'm newly taken over as a dba. Setup has been done outsourced

  by 3rd party, and I can't talk to the implentors, as they were long gone.

  When I check the DR server that only the PROD is running and the DEV was arrested for the last 12 months.

  My question is if the physical standby is stopped for almost a year, can it still be activated? or is it still valid?

  This will affect the performance of the primary database? Since he could always check heartbeat for her? or delay some process as archivers?

  How to disable the physical standby from the primary database?

  Thank you

  Petra k.

  Hello;

  "If the physical standby is stopped for almost a year, can it still be activated? or is it still valid? »

  No and no. Even a tiny production database would have generated and remove too many archives in a year for the old standby at any value. Rebuild it.

  How to disable the physical standby from the primary database?

  You could do just that: (primary side)

  ALTER system set log_archive_dest_state_2 = reporter;

  And you can clean all the parameters for DG too.

• Problem creating physical standby with RMAN

  Hi guru

  Perhaps this impact that all face you when creating physical standby DB. I'm trying to create a physical standby database Using RMAN double order a server

  (pri machine) machine on standby.

  Here are the steps I followed to create the above:

  Step 1:-activate forced logging

  SQL > ALTER DATABASE FORCE LOGGING;

  Step 2:-set up a standby Redo Log

  SQL > ALTER DATABASE ADD STANDBY LOGFILE GROUP 10

  2 > ('/ oracle/dbs/log1c.rdo','/oracle/dbs/log2c.rdo') SIZE 500 M;

  Step 3:-set the parameters of primary database initialization

  SQL > create pfile='?/dbs/pfileorcl.ora' of spfile;

  Edit the pfile to add the sleep settings, shown here:

  db_unique_name = "orcl".

  LOG_ARCHIVE_CONFIG = 'DG_CONFIG = (ORCL, orcldr)'

  LOG_ARCHIVE_DEST_2 = "SERVICE = orcldr LGWR ASYNC VALID_FOR =(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME = orcldr'"

  * .fal_server = orcldr

  * .fal_client = orcl

  * .standby_file_management = auto

  Step 4:-activate archiving

  SQL > SHUTDOWN IMMEDIATE;

  SQL > STARTUP MOUNT;

  SQL > ALTER DATABASE ARCHIVELOG;

  SQL > ALTER DATABASE OPEN;

  Step 5:-tnsnames for eve of the configuration database

  This should be done on the primary database to edit tnsnames.ora or using the command NetCA and create by the name orcldr

  orcldr =

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = TCP) (HOST = Eve-svr)(PORT = 1521))

  (CONNECT_DATA =

  (SERVER = DEDICATED)

  (SERVICE_NAME = orcldr)

  )

  )

  Step 6:-backup of database and copy it to standby mode

  This backup script must be run on primary and copied to sleep on the same mount point, run these scripts with RMAN, all files in /rman_backup need to be copied in /rman_backup on the standby server.

  $rman target.

  RMAN > run

  {

  allocate channel c1 type disk;

  allocate channel c2 type disk;

  backup of database format ' / rman_backup/%U';

  ARCHIVELOG backup all the format ' / rman_backup %U ';

  backup current controlfile to Eve format ' / rman_backup/%U';

  }

  Step 7:-availability of measures database

  Installation of Oracle software

  This should be the same version and patch group with exactly same ORACLE_HOME mount point.

  Commissioning of the listener

  Create and start a listener on the database of sleep by using NetCA, or create listener.ora in $ORACLE_HOME/network/admin

  LISTENER =

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = TCP) (HOST = Eve-svr)(PORT = 1521))

  )

  Step 8:-set of backup database initialization parameters

  Copy the pfile file created in the database primary it renames in initorcldr.ora and change these settings:

  db_unique_name = "orcldr".

  LOG_ARCHIVE_CONFIG = 'DG_CONFIG = (orcldr, ORCL)'

  LOG_ARCHIVE_DEST_2 = "SERVICE = orcl LGWR ASYNC VALID_FOR =(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME = orcl'"

  * .fal_server = orcl

  * .fal_client = orcldr

  *. LOG_ARCHIVE_DEST_STATE_2 = 'ENABLE '.

  Step 9:-installation tnsnames for the primary database

  This should be done on the pending change tnsnames.ora or using the command NetCA database and create it in the name orcl

  ORCL =

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = TCP) (HOST = primary-svr)(PORT = 1521))

  (CONNECT_DATA =

  (SERVER = DEDICATED)

  (SERVICE_NAME = orcl)

  )

  )

  Step 10:-copy a password file

  A password file must be created on the primary and copied to the standby site. The sys password must be the same on both sites. Copy orapworcl in $ORACLE_HOME/dbs and rename the file in orapworcldr

  Step 11:-create for Oracle mount points

  Mount point must be created on the standby server with the same convention used in primary education, which includes the location for controlfiles, redo logs, data files, destination of the newspaper Archives and alert logs.

  $ mkdir Pei/u01/app/oracle/oradata/orcl /.

  $ mkdir Pei/u01/app/oracle/flash_recovery_area /.

  $ mkdir Pei/u01/app/oracle/admin/orcl/adump

  $ mkdir Pei/u01/app/oracle/admin/orcl/bdump

  $ mkdir Pei/u01/app/oracle/admin/orcl/cdump

  $ mkdir Pei/u01/app/oracle/admin/orcl/udump

  Step 12:-use RMAN to restore the backup and standby configuration

  Connecting to RMAN and run the following command to create the database pending, this must be performed on the standby server after the backup copy and the tnsnames parameter.

  $ export ORACLE_SID = orcldr

  $ rman target sys/tiger@orcl auxiliary sys/tiger@orcldr

  RMAN > target double standby database dorecover;

  Here, I'm getting problem such as:

  While he was trying to connect to databases traget and auxiliary, I noticed that when RMAN is connected across the two databases it shows

  ORCL (DBID xyz)

  ORCL (unmounted)

  Here, in my opinion the second database must be the name of the standby database or auxiiary db name is Eve db which is orcldr in my case

  After this issue, I am faced with the second issues such as:

  in command

  target double standby database dorecover;

  After you change the command to

  RMAN > duplicate target database "sleep."

  RMAN-05520 database name mismatch

  Can u please let me know where I can be wrong

  Finally I have the problem after all this googling and thinking the same thing.

  Thanks to you all

  We want to create both physical standby databases cascading. The first will be used for the statement and the 2nd waterfall is Dr.

  Can you help me find documents on how configure/install this kind of scenario?

• Physical standby Archive newspapers vs

  Hi all

  11 GR 2

  Rhel6.5

  I'm confused how archivelogs be appied physical standby.

  CASES1:

  Assuming I backup my primary Db with RMAN full backup now.,

  then question crosscheck backup and delete obsolete. It will remove all archivelogs not yet taken to the waiting?

  CASE2:

  Right now my database pending is on a mode "real apply", so updates to the primary level is done directly on the eve as well, even if the archive logs have not yet carried.

  Assuming that I will delete archive records at the primary level, such that it cannot carry, will be the sleep EEG 'gaps' in its Archives logs status?

  Your comments are appreciated hightly.

  Thank you very much

  Read in the mseberg response:

• Redolog files to physical standby standby in 11g

  Hi all

  Configure a physical in 11 g standby database on Linux.

  My first question is, Create SRL (Standby Redo Logs)-

  Is - mandatory to set up physical standby?

  
  

  If I create SRL , what would be the advantage for the installation of DR?

  If I ignore it, what would be the downside for the installation of DR?

  
  

  Hello;

  Laughing out loud

  But it is a good idea.

  If your database pending is in maximum protection or maximum availability mode you need.

  If you use Real Time apply on Standby Database you need.

  If you use cascading Destinations you need.

  If you create both primary and Standby you pass quickly without additional measures or issue.

  Redo Eve can also buffer it again entering.

  Best regards

• EBS R12 dataguard physical standby

  Hi all

  BSE R12.2.4

  RHEL 6

  Most of the physical standby of companies used to be opened read only for reports.

  It comes to unload part of the load of PROD for better performance.

  Most of the reporting tools are 3rd party like Jasper, Crystal, Java, .net, Apex, Toad, Sqldev, etc.

  My question is can a simultaneous Manager EBS reports can execute on a database read-only?

  Thank you very much

• Primary RAC physical standby

  Hi all

  We plan to set up physics in waiting for our CARS database. Can anyone let us know how config in the case of RAC database? Also after you set up the night before with the protection mode max is possible to change physical Snapshot standby standby for our app objective test team?

  RDS,

  Varun

  Hi Varun,

  I recently put in place an environment of two RAC nodes to a custodian of data environment is only a single node. Nothing very special when configuring Data Guard in a CCR environment. The most important thing is that each RAC instance must send waiting for BD archivers.

  This setting is configured the destination archive database pending.

  Once the archivers reach the Data Guard environment are applied correctly and consistently to the comics of the day before.

  You have this MOS score that helps the creative process.

  Create a sleep using RMAN Duplicate (RAC or Non-RAC) (Doc ID 1617946.1)

  Yes, you can convert the Standby database to a snapshot of BD, are supported read/write operations.

  Use the command alter database convert on the eve of the snapshot;

  And when people apps to complete the test, convert it to sleep with the command:

  ALTER database convert physical standby;

  And the standby for the role of sleep and if you turn on the AutoRecover apply all redo it in anticipation of is to apply because you put the backup database into the snapshot mode.

  Is very powerful and easy.

  I hope to help.

  Best regards
