• 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

• Problem creating a Standby physical database with RMAN

  Hi all
  
  I am learning oracle dataguard and as part of the learning process of creation of database on hold.
  
  Platform: V250-fire-Sun Sparc, Solaris 10
  
  Version of database - Oracle 11R2
  
  I create standby database on the same server, so the directory structure is different.
  
  By following the instructions on the site of Oracle, I managed to create a functional physical standby database. But I'm not able to create a database with RMAN backup. Here are the steps that I follow-
  
  1 configure all the required settings on the primary database as done in creating physical standby database manually, for example implementation force of logging, the creation of newspapers ensure etc..
  
  2. settings edited on the primary database file as does everything in manual creation of physical database backup. Some of these changes are –
  
  On the primary database:
  *. FAL_CLIENT = "orcl11020" #Primary database unique name
  *. FAL_SERVER = "stdby_11" #Standby database unique name
  
  db_file_name_convert ='/ < dir >/oradata/stdby_11 ',' / < dir >/oradata/orcl11020 '
  
  log_file_name_convert ='/ < dir >/oradata/stdby_11 ',' / < dir >/oradata/orcl11020 ',' / < dir > / oradata/stdby_11/redo_mem ',' / < dir > / oradata/orcl11020/redo_mem '
  standby_file_management = auto
  
  * .log_archive_config = 'DG_CONFIG = (orcl11020, stdby_11)'
  
  * .log_archive_dest_1 = "LOCATION = / < dir > / flash_recovery_area/ORCL11020/archivelog"
  
  VALID_FOR = (ALL_LOGFILES, ALL_ROLES) db_unique_name = orcl11020'
  
  * .log_archive_dest_2 = "SERVICE = db_unique_name LGWR ASYNC = (ONLINE_LOGFILES, PRIMARY_ROLE) stdby_11 = stdby_11 VALID_FOR'"
  
  *. LOG_ARCHIVE_DEST_STATE_1 = 'ENABLE '.
  *. LOG_ARCHIVE_DEST_STATE_2 = 'ENABLE '.
  *. LOG_ARCHIVE_FORMAT='%t_%s_%r.arc'
  *. LOG_ARCHIVE_MAX_PROCESSES = 30
  
  Copied same pfile standby database and set to date follows.
  
  "* .control_files ='/ < dir > /oradata/stdby_11/stdby_11.ctl','/ < dir > / fra_stdby/stdby_11/stdby_11.ctl".
  * .db_name = "orcl1102".
  * .db_unique_name = "stdby_11".
  *. FAL_CLIENT = "stdby_11."
  *. FAL_SERVER = "orcl11020."
  db_file_name_convert ='/ < dir >/oradata/orcl11020 ',' / < dir >/oradata/stdby_11 '
  log_file_name_convert ='/ < dir >/oradata/orcl11020 ',' / < dir >/oradata/stdby_11 ',' / < dir > / oradata/orcl11020/redo_mem ',' / < dir > / oradata/stdby_11/redo_mem '
  standby_file_management = auto
  * .log_archive_dest_1 = "LOCATION = / < dir > / fra_stdby/STDBY_11/archivelog"
  VALID_FOR = (ALL_LOGFILES, ALL_ROLES) db_unique_name = stdby_11'
  * .log_archive_dest_2 = "SERVICE = orcl11020 LGWR ASYNC VALID_FOR = (ONLINE_LOGFILES, PRIMARY_ROLE)
  db_unique_name = orcl11020'
  
  3. Add the relevant information in tnsnames.ora and listener.ora files and restart the listener.
  3 created the file password with the same credentials as database primary.
  4.up - to-date RMAN backup primary database available.
  5. create controlfile standby with rman
  While the primary database s open (I tried with a primary database in montage mode as well).
  
  $> rman/paswd@rman for catalog rman target /.
  RMAN > BACKUP CURRENT CONTROLFILE TO SLEEP;
  
  6. open a new terminal standby base and start in nomount mode using the settings created - file
  $> ORACLE_SID = stdby_11
  $> export ORACLE_SID
  $> sqlplus / as sysdba
  SQL > STARTUP NOMOUNT pfile =' < rental/initfilename.ora '
  SQL > quit
  $> rman AUXILIARY / target sys/passwd@orcl11020 catalog rman/passwd@rman
  RMAN > duplicate TARGET DATABASE ENSURES DORECOVER;
  
  
  RMAN ends without error but the archive logs is not eliminated. Looking at the newspaper, following caught my eye.
  
  Logging of 1017 errors received on the eve
  ------------------------------------------------------------
  Verify that the primary and standby use a password file
  and remote_login_passwordfile shared or EXCLUSIVE.
  and the SYS password is the same password files.
  error ORA-16191
  ------------------------------------------------------------
  FAL [client, ARC2]: error 16191 connection at orcl11020 for the extraction of the gap sequence
  Errors in file /<>dir > / diag/rdbms/stdby_11/stdby_11/trace/stdby_11_arc2_24321.trc:
  ORA-16191: customer main newspaper not connected waiting for shipment
  Errors in file / < dir > / diag/rdbms/stdby_11/stdby_11/trace/stdby_11_arc2_24321.trc:
  ORA-16191: customer main newspaper not connected waiting for shipment
  
  
  Thus on primary and standby I confirmed
  
  SQL > show parameter remote_login_passwordfile
  
  VALUE OF TYPE NAME
  ------------------------------------ ----------- ------------
  Remote_login_passwordfile string EXCLUSIVE
  
  Make double sure that the password files are the same, I stop databases, delete the password and recreated with the same credentials.
  Password files are called - orapworcl11020 and orapwstdby_11
  
  Can someone guide me where thisngs wrong here please.

  How did you create your file of passwords on the rescue system?

  I will consider your entire post and see what jumps.

  * 3. Created the file password with the same credentials as primary database.*

  You cannot create the password on the eve of 11.1 from file. You must COPY the password from the primary to the wait for passwords to match. What I do, is copy and rename.

  E.g.

  I copy orapwPRIMARY to the standby server and rename it orapwSTANDBY

  (Your names varies)

  It could start to work if you do this with a stop and restart of recovery on the day before. Newspapers make up probably just.

  If you find this helpful please mark as well.

  A few things about the parameters (they can make no difference)

  This

  Log_archive_dest_1 =' LOCATION = /

  /flash_recovery_area/ORCL11020/archivelog VALID_FOR = (ALL_LOGFILES, ALL_ROLES) db_unique_name = orcl11020'

  Would it be

  Log_archive_dest_1 =' LOCATION = USE_DB_RECOVERY_FILE_DEST VALID_FOR = (ALL_LOGFILES, ALL_ROLES) db_unique_name = orcl11020'

  Not sure that you need.

  LOG_ARCHIVE_FORMAT='%t_%s_%r.arc'

• Before physical deployment standby with RMAN incremental backups.

  This method is available in 10g:

  http://Web.Stanford.edu/dept/ITSS/docs/Oracle/10gR2/server.102/b14239/scenarios.htm#CIHIAADC

  For 11g:

  http://docs.Oracle.com/CD/E11882_01/server.112/e41134/RMAN.htm#SBYDB00759

  For 12 c:

  http://docs.Oracle.com/database/121/BRADV/rcmadvre.htm#BRADV685

  According to dosc 10 g, the scenario is simple:

  1. create an incremental backup to SNA required on primary and copy it in standby mode

  2 save the backup in sleep mode and perform a recovery

  11 g dosc, we must recreate the standby control file and update the file names before performing the recovery.

  12 c introduces the new method - recovery on network, but again, we must recreate and standby control file update.

  The question is: why we must create new controlfile ensures g 11 and 12 c and can we use a simple method of 10g?

  Thank you.

  Hello

  1 why the incremental backup application does not update standby controlfile?

  -Your database pending is be retrieved using the incremental backup. This does not update the eve controlfile. Your standby controlfile completely ignores the last CNS to the primary database.

  2. what happens if we leave the old standby controlfile? RFS will record new logs of the primary, but will ignore them MRP? If so, can update us standby controlfile by manually applying the following log?

  -Your old standby controlfile is unaware of the last CNS to the primary database.

  As Mseberg said, trying things on a test computer and you will have the answers to your questions.

  Kind regards

• Roll forward standby with RMAN incremental backup when used DG broker

  Hello
  
  I'm about to use the process defined in the note: steps to roll forward a database ensures the RMAN incremental backup using during primaries and Eve are in the file [836986.1 ID] ASM system. I'm on 11.1.0.7.
  
  However, it does not mention the DataGuard broker.
  Did someone played this process when you use the broker.
  The broker he manages properly?
  Does it matter if the broker is upwards or downwards during the physical recovery of standby or replacement of control file?
  Should the broker configuration be re-created?
  
  Thank you.

• Primary and primary physical Standby with an incomplete configuration

  What could be difficulties if the primary database is not the FAL_CLIENT configured on the primary database to point to itself?

  I understand that you must have on the primary:

  fal_server = < physicalStandby > and

  fal_client = < primaryDatabase > don't default fal_client in primary?

  Good point.

  fal_server =

  fal_client =

  And then pass them after a failover of coherence and transparency.

  Thanks Marshall!

• 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.

• 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_file_name_convert='/testdb/','/testdb /'

  * .db_name = "testdb".

  * .db_recovery_file_dest ='/ orafra'

  * .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...

  If you still think it's something is not acceptable, you must have SR with support to analyze why he does not abandon SRL when controlfile_type is "underway".

• Establishment of a physical standby on a server with a different structure

  I'm having some trouble putting in place a database of physical intelligence.
  
  The main database has a different naming structure the day before and they are on different sites.
  Physical is/var/hpsrp/ctrorp03/oradata/u0x / < DB_NAME > / < DB_UNIQUE_NAME > and Eve is/var/hpsrp/drforp03/oradata/u0x / < DB_NAME > / < DB_UNIQUE_NAME >.
  
  I put db_file_name_convert '< MAIN path >', '< PATH of EVE >' multiplied by the number of paths in the form of pairs.
  I created an empty database for the day before and after taking a full backup of the primary with the control file and the control file ensures.
  
  Now, I touched the issues:
  The incarnation of DB numbers are different.
  When I try and do a normal restore for example set dbid, restore controlfile; Mount; It fails as it tries to find files in the primary structure and the structure not to sleep.
  When I try to rename via set newname or auxname it can't find files to restore I guess because of the id of the incarnation
  If I put the id of the incarnation and try to restore backup it fails as an identifier of the incarnation do not match.
  
  I have tried looking through various forums and documentation, but impossible to find a solution, probably can't see the forest for the trees well because there are so many things.
  
  Someone there done that type of configuration before and can give me some advice?

  Ok

  What I consider 'sleep data by is an active database with RMAN'

  http://www.Visi.com/~mseberg/standby_creation_from_active_database_using_rman.html

  The thing with your is the location of your LOG files and DATA.

  Where are they now?

  Where they need to be on standby mode?

  Note that this method use a SPFILE so that the settings are made to change the location of the files.

  If you do it right the order is as simple as

  $ORACLE_HOME/bin/rman target=sys/@primary auxiliary=sys/@standby
  
  RMAN>duplicate target database for standby from active database NOFILENAMECHECK;
  

  Also I and others trying to help you do it for the points. Marking of some of these useful tells us that we are really helping and not only to waste time.

• Problem with data hold creating a Physical Standby Database turorial

  There is a tutorial for creating a Data Guard Physical Standby Database:
  http://www.Oracle.com/technology/OBE/11gr1_db/HA/DataGuard/physstby/physstdby.htm
  
  I tried to install it on two servers. One for a primary database (deuxieme for the physical standby.
  I have the error on creating C. the database of watch on the #6 action network:
  
  «On the rescue system, set the ORACLE_SID to your < SID physical standby > environment variable (i.e. orclsby1) and start the instance in NOMOUNT mode with the text initialization parameter file.»
  
  When I try to connect to the instance that is idle, there is an error pops up:
  
  C:\ > sqlplus / as sysdba
  
  SQL * more: version 11.1.0.7.0 - Production Thursday, May 21, 16:28:10 2009

  ERROR:
  ORA-12560: TNS:protocol adapter error
  
  I ' v checked listener, and it is managed. There is no database service because there is still no database.
  
  The question is did some data installed a guard configuration using this tutorial? Are there errors in there? What should I do to complete the installation?

  On Windhose for any service must have been created using the oradim command.
  Oracle tutorials are usually centered on Unix, because Windhose is an odd man out, so they do not discuss.
  "Please do the needful" and create the service before the beginning of the instance in nomount mode

  Tip: oradim is documented and has a help = clause of y.

  IIRC there is an option in control database (in the part of the interview) that automates everything.

• Backup with rman backup sets

  Hi experts. I know about backup of backup without rman example sets but I want to know is there a way to backup with rman backup sets.

  Perhaps it works for your condition.

  RMAN > backupset backup is complete before ' sysdate-1';

• Test failover with physical standby

  Hello

  I have a primary at base of 11.2.0.4 (cars) and an instance of unique physical standby (on a virtual machine).

  I need to test failover.

  I'm looking some procedure or steps.

  Can they be valid?

  On primary

  • change the built-in system again to standby_db_name;
  • alter system archive log current;
  • Stop the shipment of archive: alter system set log_archive_dest_state_2 = "DAVID";

  Standby:

  • ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
  • ALTER DATABASE RECOVER MANAGED STANDBY DATABASE FINISH;
  • stop immediately; --> the snapshot can be done at this stage or need to get after 'RECOVER MANAGED STANDBY DATABASE CANCEL'
  • Make a snapshot of the virtual machine
  • startup nomount
  • ALTER database base_de_donnees eve of Mount;
  • ALTER DATABASE ACTIVATE PHYSICAL STANDBY DATABASE.
  • ALTER DATABASE OPEN;

  Test what finish

  Standby:

  • stop the database
  • restore from snapshot
  • Put the database in recovery mode

  Elementary school:

  • Allow destination of the Journal 2

  What do you think?

  Use the snapshot before...

• Log_archive_format with physical standby

  Oracle RDBMS: 11.2.0.2 (RAC) on RHEL 5.6
  
  
  We need to define any particular value for log_archive_format parameter when creating physical database from the night before?
  
  In our primary, the value of the parameter is log_archive_format = 't_ % s_ % r.dbf % '. Do we need to change it to another value or can leave us like this for the physics of the standby database?
  
  Number of documents online in various blogs include log_archive_format ='% t_ % s_ % r.arc as well as all the other required parameters for the physical creation of the standby database. I am bit confused, can someone please clarify.
  
  
  Thank you

  Hello;

  Do we need to set any particular value for log_archive_format parameter while creating physical standby database?
  

  N °

  In our primary the parameter value is log_archive_format='% t_% s_% r.dbf'. Do we need to change it to a different value or can we leave it like that for physical standby database?
  

  I love them the same thing only it gaps check more easily. Yours seems to be the default for Linux.

  SQL> show parameter log_archive_format
  
  NAME                                 TYPE        VALUE
  ------------------------------------ ----------- ------------------------------
  log_archive_format                   string      %t_%s_%r.dbf
  SQL> 
  

  On all mine, I don't put that and allow you to apply the default value for the parameter.

• How to check if physical Standby is in phase with the primary

  Hi all
  
  I'm new in Data Guard. In our current production, my boss asked me to write a shell scripts for monitoring physical standby and archive primary's sync (gap of archive)
  
  I refer metalink [861595.1 ID], but when I ran the first query to the primary node, the screen lock.

  Because of this is the production environment, so I had put an end to the session, anyone can teach me or share with me the physical monitor in standby mode scripts is sync with primary or not? Or you encounter the above problem when you run the SQL code?
  
  My version of db is Oracle 11.2.0.1.0
  
  
  Thanks in advance.
  
  Kind regards

  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

• 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

  Arturo
