• 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

• 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.

• 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.

  Physical STANDBY

  SQL > ALTER DATABASE ENABLE PENDING DATA base;

  SQL > STARTUP MOUNT FORCE;

  SQL > alter database base_de_donnees ensures together to improve performance;

  SQL > ALTER DATABASE OPEN;

  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.

• 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.

• Test of physical Standby DB 11 g

  Hi all

  My company is considering a DR test in a few months, and since I never did this until I was wondering what would be the best way to go on the DB pending tests. This is a database of 11G (11.2.0.3). I read the following articles:

  http://gavinsoorma.com/2009/09/11g-snapshot-standby-for-real-time-testing/

  http://www.Pythian.com/blog/testing-a-physical-standby-database-in-Oracle-10G/

  http://www.Oracle.com/technetwork/articles/SQL/11g-DataGuard-083323.html

  From what I can tell the snapshot method is the easiest. My main question is when the primary method still must send the archive logs to the waiting or can I defer only to archive log shipping? How we test normally the site of DR is completely disconnect the network connections and put everything in place for the primary will not be able to speak to the waiting and vice versa. Or is the best method to follow the other article that speaks using the flashback database?

  Thanks in advance for your help.

  From what I can tell the snapshot method is the easiest. My main question is when the primary method still must send the archive logs to the waiting or can I defer only to archive log shipping?

  Are you in 11g, yes instant is a nice feature to test your intelligence. If you enable the destination, there is no problem. Meanwhile if too many records are generated and then it takes a long time to get a site to DR.

  How we test normally the site of DR is completely disconnect the network connections and put everything in place for the primary will not be able to speak to the waiting and vice versa

  You can also completely disconnect the primary DR and tests after the conversion of the physics on the eve of the snapshot if it is your condition to do so.

  Or is the best method to follow the other article that speaks using the flashback database?

  In traditional flashback, you will need to take care just like the creation of restore point with guarantee, mode standby manually and run again then flashback to the restore point. Snapshot is really simple and easy to use. If am in your position of course I use the standby database snapshot.

  Hello;

  Sorry for the delay. I live on the other side of the world, and I have a few questions to do with my family.

  Port 1521 is the default value for the listener, so if your listener uses different ports, they need to be taken into account in the firewall.

  The error you are getting is related to network. You check the configuration of the receiver and confirm the port you are using.

• Reader only a physical standby Clock Data Guard?

  Hi all

  We try to use TimesTen 11.2.2.4.1 as a memory cache read-only for a 11.2.3.0.7 on Linus RedHat 6.3 Oracle schema, all using Oracle Data Guard to replicate the Oracle instance through geographically remote sites. At each site, we would like to have two instances of TT, synchronization with the local instance of Oracle 11 g. It works very well against the master DB, but TT agents will be able to synchronize against physical standby instances?

  The problem, seems, is that the agent of TT uses structures dedicated in the master Oracle (related to the grid of cache), instance that will be replicated to instances of Eve. Is TT agent able to use the read-only, structures to complete replication synchronization, or is this unworkable approach? What would be your advisor as a way to do this?

  Thanks for your help,

  Chris

  No, I'm afraid that will not work and is not supported. We support the use of groups of READONLY and AWT cache in collaboration with Data Guard in the following configuration (documented in the Guide of Cache TimesTen IMDB):

  1 data Guard is configured as synchronous physical standby

  2. all the caches of TT run against Oracle DB

  3. in the event of a failover of Data Guard, TT hiding can be migrated to run against the DB who now has beed promoted active to standby

  It is the only supported configuration.

  Kind regards

• 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.
