• Oracle will consider the creation of a day 2 hands on the documentation for Data Guard?

  Hello

  Oracle will consider the creation of a documentation of son of hands 2 day for Data Guard?

  There is already an OTN 2 day of CARS and performance tuning documentation.

  Thank you

  Updated - she sent the link to this topic for the Product Manager Data Guard.  As a result, Oracle may or may not consider creating 2 days hands on Data Guard documentation, but no doubt they consider at least considering creation day 2 hands on the Data Guard documentation.

• Database is configured for Data Guard

  I'm lance a UTF8 conversion on a development database, which has been cloned from Data Guard. There is a warning in the Migration status: "database is configured for Data Guard" which is looking at DMU to determine this? The database is opened in read-write mode and it behaves like a primary database (I have the MISP scanner and run updates to address representations not valid). I would like to know what I need to update the settings.

  This prevent me to convert tables using DEC? When I try to select this option for all tables I get the message, "CDS does not support conversion method"Copy data using CREATE TABLE AS SELECT"for tables that are involved in a process like capture Oracle Streams, or apply.". Another method of conversion available for the table.

  Thank you

  Ben

  CDS checks if the DG_BROKER_START parameter is set to true.

  The problem with the ETG is independent of the Data Guard. The CDS is true for tables which:

  -are asynchronous stream capture source, or

  -update conflict managers have, or

  -DML managers have, or

  -conflict resolution settings have

  The above tables are considered to be configured for Oracle Streams and are not supported by the method of conversion of DEC. This is because the DEC method creates a copy converted the table and falls from the original. The CDS is not able to move the configuration information from the old table to the new flow.

  Thank you

• 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,

  Jim

  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.

• Question about LGWR Sync for Data Guard

  Hi all
  I have a general question related to guard data. We have a primary database of CARS and a day before RAC database which is two thousand miles. If I ping the main site backup site, the average response time is 30 ~ 50 miliseconds. We intend to configure the DG mode of maximum availability with the LGWR SYNCHRONIZATION options. If the ping network takes at least 30 milliseconds, it will add milliseconds to at least 30 x 2 late before primary LGWR can write to the primary database. Anyone have a similar experience? It will have an impact on the performance of the database? Is the case, we will use Maximum performance mode or maximum availability with the ASYNC option? Feedback is very much appreciated.
  
  Thank you.

  From a point of view, really, it should depend on your business and functional requirements. If your company can afford to lose performance of database data, then you must use mode maximum performance with the ASYNC option. In my opinion, with the configuration of Eve where the backup servers are at 2,000 miles, I'd go with maximum performance mode.

• TAF TNS entry for active data guard

  Hello world

  Need your advice on the configuration of the TNS entrance side transparent client failover of the DB in waiting in a Data Guard configuration active?

  Normally, I create a service manually and configure this service to start or stop according to the change of role of database. Then have personalities of the two sites in the entry of TNS (example below).

  TEST =

  (DESCRIPTION =

  (FAILOVER = ON)

  (ENABLE = BROKEN)

  (LOAD_BALANCE = TRUE)

  (ADDRESS = (PROTOCOL = TCP) (HOST = VIP1-SITE1)(PORT = 1521))

  I learned this method of-> http://uhesse.com/2009/08/19/connect-time-failover-transparent-application-failover-for-data-guard/

  Is there a better way to do this? Can we achieve this using an AMT only?

  I think I found the answer. According to the document oracle practices best client failover, the service can be configured to start automatically on the standby server when the role of the db is changed. This can be achieved by creating a service with srvctl with option '-l PRIMARY' on both sites

  For example:

  Main cluster: srvctl add service d Austin s oltpworkload r - ssa1 ssa2 ssa3, ssa4-l primary SCHOOL - q TRUE EI SESSION m BASE w 10 - z 150

  Cluster of relief: srvctl add service d Houston s oltpworkload - r BSR1, ssb2, ssb3, ssb4 - l PRIMARY - q PURE EI SESSION m BASE w 10 - z 150

  Documentary link--> http://www.oracle.com/au/products/database/maa-wp-11gr2-client-failover-173305.pdf

  Also the entrance to the AMT must be created with two descriptions, one for primary and one for standby

  TNS_DG =

  (DESCRIPTION_LIST =

  (LOAD_BALANCE = OFF)

  (FAILOVER = ON)

  (ENABLE = BROKEN)

  (DESCRIPTION =

• Data Guard archive political deletion log

  Hi all

  I configured the data guard with 2 bases Eve in oracle 11g.

  I want to use rman to delete archives on all servers.

  I have configured no FRA, no recovery catalog.

  My question is:

  If I delete waiting til sequence # 1627 and on primary sequence til = # = 1620 or vice versa this would cause problems for Data Guard.

  I say delete until the different sequences # on primary and standby cause problems for synchronization?

  Thank you

  So if I understand delete archivelog to sysdate - or delete archivelog all completed before sysdate n is not the archivelog deletion policy you put on RMAN?

  She depends on it. The note was made at the base of the MOS document how ensure that RMAN is NOT delete archived logs that have not yet shipped to standby mode (Doc ID 394261.1)

  Delete archivelog to sysdate - depends on all of the deletion policy. If the deletion policy is set on "applied pending all", then it does not delete the archives, if they are not applied on the day before. If the deletion policy is set to none, then it does not check if the archive is applied on the eve and deletes them directly.

  Last Archive generated on primary:

  SYS@oraprim > select max(sequence#) from v$ archived_log;

  MAX(SEQUENCE#)

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

  114

  Last check-in applied in mode ensures:

  SYS@orastb > select max(sequence#) from v$ archived_log in case of application = 'YES ';

  MAX(SEQUENCE#)

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

  109

  Delete policy set to NONE on primary:

  RMAN > show archivelog deletion policy;

  using the control file of the target instead of recovery catalog database

  RMAN settings for database with db_unique_name ORAPRIM are:

  CONFIGURE THE NONE ARCHIVELOG DELETION POLICY;

  RMAN > delete archivelog until 'sysdate;

  allocated channel: ORA_DISK_1

  channel ORA_DISK_1: SID = 60 type of device = DISK

  It checks if the archive has been applied on the day before. As the 110 to 114 sequence is not applied in the waiting, the archives are not deleted on the primary.

  Hope that gives you a clear picture of how it works.

• Data Guard and connectable to database

  Possible to have some project documents in a CDP that is used for Data Guard and other PDB files don't not ITIS?

  No, not in the current version. You must use the PDBs als for DG or nothing.

• Data Guard Performance: apply Lag

  In Cloud control there is a measure called "Lag (seconds) apply" under a group called 'Data Guard Performance '.  I created an alert on this metric rule.  However, I want to know what thresholds are defined for this measure, if I look under the supervision of models.  He isn't here.  There are also a number of other Performance measures of custody of data that is, I can't find or add in templates.  Can anyone help?

  From the home page of a database on hold, you can navigate to the (Oracle database > surveillance >) metrics and Collection settings page and select all the metrics view to check or set thresholds for (Data Guard Performance) metrics apply Lag. Note that by default, no limit is set for this measure.

• A few questions about the design of Data Guard

  Hi, I have a few basic questions around design Data Guard

  Q1. Looking at the instructions of Oracle for the creation of a logical standby, he recommends first creating a physical standby and then convert waiting logic. However, I thought that a logical standby might have a totally different physical structure of the primary. How can this be the case if a logical standby first starts his life pending physical (where the structure must be the same)?

  Q2. It is a normal practice to back up your database before as well - if yes why?

  Q3. Can RMAN back up a database of the day before while he is in the State mounted (rather than opening it)?

  Q4. What is the point of cascade redo apply rather than just get the primary ship to each standby?

  I guess you could try to reduce the latency of node to node if some the day before were quite remote from the primary

  Q5. Is it possible to convert a physical logical Standby?

  Q6. What number best of Standby, you can have - Oracle suggests 30 but I thought I remember reading somewhere regarding the 11 GR 2, that this limit has now been increased?

  Thank you

  Jim

  Hello again;

  "begins each logical waiting first her life on hold physical?"

  Its the only way I ever did. I think it is the simple way to do it.  By the presence of a physical standby first you have already confirmed the network and most of the settings for Data Guard so that you can focus on only the logic of the standby database configuration.

  Chapter 3 of this book, it's easy:

  11 GR 2, I know that the Data Guard Setup is a free option that comes with the Enterprise Edition, you don'r require an additional license for it.

  But I read somewhere the Data Guard Broker and using DGMGRL is a cost extra option? Is this true?

  Help kindly understand this?

  Thank you.

  Hello;

  This is part of the Enterprise edition.

  The following are required before you can use the broker:

  The main and backup databases must use the same version of Oracle

  Database 11g and each can be installed in a single instance or multiple instances

  environment. The database must be allowed for Oracle Enterprise Edition or
