• Refresh the MV of standby Active Data Guard

  Is it possible to refresh a materialized view (quick or full) come from a standby database Active Data Guard open in read mode only w/apply?  Or can I just do the update of the primary?

  Hello mseberg,

  You made a very good point about the definition of a database of the READER.

  After you have answered, I found in MOS: create a distributed materialized view based on a master table on a database in read-only (Doc ID 276023.1)

  This explains that it is NOT possible to make a fast refresh of a database shall RO.  However, it *peut* be possible to do a complete refresh of a standby Number.  It depends on the query used to define the MV.  If the RDBMS Analyzer determines the MV is *able* to fast refresh (even if there may not need it right now), so you can't do a full refresh since the eve of the RO.  If the parser determines that the request is NOT able to fast refresh, then you can do a full refresh since the eve of the RO.  I tested this script on 11.2.0.3.8 and found to be true:

  CREATE THE MIMI MATERIALIZED VIEW. MV_TEST

  TABLESPACE USERS

  IMMEDIATE CONSTRUCTION

  COMPLETE REFRESH

  AS (SELECT * FROM TEST@MIMI_ROSTBY);

  ORA-16000: database opened for read-only access

  ORA-06512: at "SYS." DBMS_SNAPSHOT_UTL', line 364

  ORA-06512: at "SYS." DBMS_SNAPSHOT_UTL', line 446

  ORA-06512: at line 1

  Now, I've changed the MV query to use a 'one time' feature (ROWNUM), which causes the query become complex (not able to fast refresh).  I can now create a MV on the day before RO, because the query is no longer able to fast refresh and requires no registration on the eve of the RO:

  CREATE THE MIMI MATERIALIZED VIEW. MV_TEST

  TABLESPACE USERS

  IMMEDIATE CONSTRUCTION

  COMPLETE REFRESH

  AS (SELECT * FROM TEST@MIMI_ROSTBY WHERE ROWNUM > 0);

• problem in physical recovery standby database (Data Guard) by rman

  scenarios is followed
  
  1. in rman, I create a backup of database Eve by this command:

  This is because as soon as you open the standby database, application of roll forward stops. At least that's true up to 10 gr 2, 11 g, you have the option "Active Dataguard" (requires an additional license), which allows to apply, while the database is open.

• Reading only the numerical value of data packet?

  I have an entry that gives me: 122345, %, 0000 0000

  I want just the 122345 part so that I can graph the value in real time as data are to be listened to in the computer. How can I choose for this? Now I just have a straight read command and read buffer indicator, I did just unroll the package according to the number of bytes I tell her to read.

  Watch the channel for several functions in the palette of the format string.  If the values are always integers, and always at the beginning of the string, the decimal string to number feature will work without extra effort.

• Insert into a primary database of Eve Active Data Guard

  I use Oracle EE 11.2.0.3.8 on Solaris 10.

  I read that it is possible to do an insert in my database for the standby Active Data Guard by redirecting the insert to get on the primary via DB link.  I GLOBAL_NAMES set to TRUE and he needs to stay that way.  This means that I can't create a DB link pointing to my first as such:

  CREATE DATABASE LINK PROD. WORLD WITH THE HELP OF "PROD_PRIM";

  How can I get around this in order to insert data in my standby ADG primary?

  Hello;

  There is an article about it here by Uwe Hesse:

  http://uhesse.files.WordPress.com/2012/03/realtimequery.PDF

  I understand that if GLOBAL_NAMES is true, then, the database link must have the same name as the database in which it connects.

• Additional logging with Oracle 10 g 2 streams and Data Guard

  Hello
  
  I have a physical environment with DB Oracle 10 g 2 and Standby with Data Guard DR CONF. At the present time, this environment will be extended to a pattern of replication using 2-way Oracle Streams Replication (for replication to the central office of this branch, other channels will be added soon). The primary DB is replicated to the other primary DB (at the telephone exchange remotely).
  
  So, there's my question: it is completely necessary to specify an additional record on data sources (primary) to set the 2-way Streams replication? and, if it is completely necessary, then, can configure additional connection on primary without affecting their physical Standby, or what I have to do something special?
  
  Thanks in advance.

  Yes, for the streams you need additional registration. There is no impact on databases physical standby.

  Thanks a lot for what confirms.

  Fix.  There is no way to grant read-only access to load map data.

• Block corruption on the physical Standby database

  Hi all

  We are facing corruption block on our database of physical intelligence. The same has been detected using commands below and several blocks were found to be corrupt.

  RMAN > backup validate check the logic of database;

  As it is a basic data watch no backup is present, pulling the command below did not help

• Purge logs archiving on things primary and Standby and for Data Guard RMAN

  
  Hi, I saw a couple of orders in regard to the purge archive records in a Data Guard configuration.

  Set UP the STRATEGY of SUPPRESSION of ARCHIVE to SHIPPED to All RELIEF;

  Set UP the STRATEGY of ARCHIVELOG DELETION to APPLIED on All RELIEF;

  Q1. The above only removes logs archiving to the primary or primary and Standby?

  Q2. If deletions above archive logs on the primary, is it really remove them (immediately) or does the FRA to delete if space is needed?

  I also saw

  CONFIGURE ARCHIVELOG DELETION POLICY TO SAVED;

  Q3. That what precedes, and once again it is something that you re primary side?

  I saw the following advice in the manual of Concepts of data protection & Admin

  Configure the DB_UNIQUE_NAME in RMAN for each database (primary and Standby) so RMAN can connect remotely to him

  Q4. Why would I want my primary ro connect to the RMAN Repository (I use the local control file) of the standby? (is this for me to say define RMAN configuration settings in the Standby) manual

  Q5. Should I only work with the RMAN Repository on the primary or should I be also in things in the deposits of RMAN (i.e. control files) of the standby?

  Q6. If I am (usually mounted but not open) Physics, of standby I able to connect to its own local repository for RMAN (i.e. control based on files) while sleep mode is just mounted?

  Q7. Similiarly if I have an old lofgical (i.e. effectively read-only), to even connect to the local RMAN Repository of Eve?

  Q8. What is the most common way to schedule a RMAN backup to such an environment? example cron, planner of the OEM, DBMS_SCHEDULER? MY instinct is cron script as Planner OEM requires running the OEM service and DBMS_SCHEDULER requires the data runs?

  Any idea greatly appreciated,

  The above only removes logs archiving to the primary or primary and Standby?

  When CONFIGURE you a deletion policy, the configuration applies to all destinations archive

  including the flash recovery area. BACKUP - ENTRY DELETE and DELETE - ARCHIVELOG obey this configuration, like the flash recovery area.

  You can also CONFIGURE an archived redo log political suppression that newspapers are eligible for deletion only after being applied to or transferred to database backup destinations.

  If deletions above archive logs on the primary, is it really remove them (immediately) or does the FRA to delete if space is needed?

  Its a configuration, it will not erase by itself.

  If you want to use FRA for the automatic removal of the archivelogs on a database of physical before you do this:

  1. make sure that DB_RECOVERY_FILE_DEST is set to FRA - view parameter DB_RECOVERY_FILE_DEST - and - setting DB_RECOVERY_FILE_DEST_SIZE

  2. do you have political RMAN primary and Standby set - CONFIGURE ARCHIVELOG DELETION POLICY to APPLY ON ALL STANDBY;

  If you want to keep archives more you can control how long keep logs by adjusting the size of the FRA

  Great example:

  http://emrebaransel.blogspot.com/2009/03/delete-applied-archivelogs-on-standby.html

  All Oracle is worth a peek here:

  http://emrebaransel.blogspot.com/

  That what precedes, and once again it is something that you re primary side?

  I would never use it. I always had it put it this way:

  CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;

  I would use only 'BACKED UP' for the data protection system. Usually it tell oracle how many times to back up before removing.

  Why would I want my primary ro connect to the RMAN Repository?

  Because if you break down, you want to be able to backup there, too.

  Also if it remains idle for awhile you want.

  Should I only work with the RMAN Repository on the primary or should I be also in things in the deposits of RMAN (i.e. control files) of the standby?

  Always use a database of catalog RMAN with Data Guard.

  If I am (usually mounted but not open) Physics, of standby I able to connect to its own local repository for RMAN (i.e. control based on files) while sleep mode is just mounted?

  Same answer as 5, use a catalog database.

  Similiarly if I have an old lofgical (i.e. effectively read-only), to even connect to the local RMAN Repository of Eve?

  Same answer as 5, use a catalog database.

  What is the most common way to schedule a RMAN backup to such an environment? example cron, planner of the OEM, DBMS_SCHEDULER? MY instinct is cron script as Planner OEM requires running the OEM service and DBMS_SCHEDULER requires the data runs?

  I think cron is still, but they all work. I like cron because the database has a problem at work always reports its results.

  Best regards

  Summary

  Always use a database with RMAN catalog.

  Always use CRF with RMAN.

  Always set the deletion «To APPLY ON ALL STANDBY» policy

  DB_RECOVERY_FILE_DEST_SIZE determines how long to keep the archives with this configuration.

• Rename a data file in a physical standby

  Hi all

  I have the following problem.

  Oracle Enterprise Linux 64-bit 11.2.0.2.0

  Primary and standby are configured with standby_file_management = MANUAL

  I added a tablespace with a primary data file a few days ago.

  Today, I realized sleep did not change due to the following error:

  
  

  ORA-01111: name for the data file 13 is unknown - rename it to the correct file

  ORA-01110: data file 13: ' / oracle1/11.2.0.2/dbs/UNNAMED00013'

  ORA-01110: data file 13: ' / oracle1/11.2.0.2/dbs/UNNAMED00013'

  According to the MOS it says I should rename database in standby mode, but it does not allow me to do so, it is said that dB must be open; but I can't open it because it is a standby DB.

  Even if I want to open read-only, it says:

  SQL > ALTER DATABASE OPEN read-ONLY.

  ALTER DATABASE OPEN READ ONLY

  How can I solve it?

• Open physical standby mode read/write to test without return of flame

  I have successfully installed a physical database standby 10 gr 2 (10.2.0.3 EA). Now I have to test my application with the database pending, so I have to
  Open (enable) in read/write mode (don't want to use FLASHBACK DATABASE), I know that I have to recreate the database pending scracth after completing the test.
  
  So far, I did these steps:
  
  1. on the PRIMARY database, I disabled the log destination archive:
  ALTER system set log_archive_dest_state_2 = 'reporter ';
  2. on the day before, I cancel managed recovery
  ALTER database recover managed standby database cancel;
  
  
  Can anyone provide the remaining steps to open the write standby database? I searched the oracle documentation and all the steps require the flashbak database.
  
  Thanks in advance.
  
  S.H.

  Ok

  You could do a failover on the eve (without doing anything at the elementary level)

  So to run these on your watch.

  SQL > alter database recover managed standby database cancel;
  Database altered.
  SQL > alter database recover managed standby database finish;
  Database altered.
  SQL > alter database validation at the transition to the primary with the stop of the session;
  Database altered.
  SQL > alter database open;
  Database altered.

  Then simply stop the day before (not primary) and rebuild as the standby again. Delete and re-create.

  Make sure that your Data Guard alter system set log_archive_dest_state_2 = delay; Are fixed on both sides.

  This can help:

  http://www.Oracle.com/technetwork/database/features/availability/MAA-WP-10gR2-faststartfailoverbestp-131997.PDF

  You want to split the day before with really nothing do in elementary school except reporter.
