  What you have shown here is the log_archive_dest_2 of the primary database. You must clear the log_archive_dest_2 of the standby database too.

  The error is speaking on the parameter log_archive_dest_2 of the database pending. 12 c, then the broker configuration, you must clear the log_archive_dest_2 (destinations archive remote) on the primary and standby databases. DG broker would take care of her.

  On autonomy in standby:

  SQL > alter system set log_archive_dest_2 = ";

  And then try to add the standby database to the broker configuration.

  John;

  I checked my setup note and here is what I have on your common error:

  ORA-16607 on SHOW CONFIGURATION
  
  Problem: After creating your configuration and adding the standby database, you issued a SHOW CONFIGURATION as suggested. Instead of the expected SUCCESS, the report ends up with
  
  Warning: ORA-16607: one or more databases have failed
  
  . Checking with oerr ora 16607 was not very helpful (see above), and you neither can find anything in your alert.log nor any trace files.
  
  Cause: Probably at least one of your databases is not using an SPFILE.
  
  Solution: Check whether your databases have an SPFILE associated. It is usually located in $ORACLE_HOME/dbs/spfile$ORACLE_SID.ora. If it does not exist, create it: Login to your database as SYSDBA, and issue the command CREATE SPFILE FROM PFILE;. Even if it exists, to make the database using it you need to restart the instance - it must be used already at startup.

  If the DG broker is not enabled then the switch on doesnot take place.

  You must perform the failover manually.

  Another question.

  IS the DG and DR are the same.
  I have head that DR archives logs doesnot recovery takes place automatically. We must manually push .is this true?

  If it is ENTERPRISE Edition, so no need to copy archives manually, if you have configured properly everything is automated.

  DR - disaster recovery, how do you plan to recover from the loss of data and methods.
  DG - Dataguard (method)

  While you can use the broker to start and stop instances but with CARS, it is preferable to use srvctl.

  You don't need to change the sleep state or the primary before stopping, either. Account assignment is blocked on the standby srvctl stop this instance without any damage.

  Hello

  I think that the main issue is due to the location of the configuration files broker is not set to the same common place at the primary level.

  Note: in the case of CCR, you must have broker configuration files on the shared location and definition of the DG_BROKER_CONFIG_FILE1 and DG_BROKER_CONFIG_FILE2 to the same values in all the nodes.

• Database broker and dataguard Creaton of Eve

  Hi Experts,
  
  I use Linux with Oracle version 11 GR 2. We have plans to create a database of physical intelligence and also configure dataguard broker for the standby database.
  Also, I read the documents that active dataguard is a feature on 11g. It is not possible on 10g?
  
  Can someone give me please the steps to create the standby database and configure the dataguard broker.

  Hello

  Check this thread DR synchronize with primary

  Also, to check whether or not the managed recovery is underway on the standby database, run the following query:

  SQL > select process, status, sequence # from v$ managed_standby;

  If process columns is a value such as MRP, then the managed recovery is underway on the standby database.

  Hope this is clear.

• Small questions about Dataguard

  Hello

  I have a few questions about Dataguard. I'm new to DG, carry me so for the display of these fundamental questions:

  We plan to install Oracle 12 c to Win 2012 R2 with primary and physical intelligence on different physical servers. We are looking for HA solution, but cannot afford to license CARS. The two primary & Eve are going to be in the same data center connected via a 1 gigabit network. So I have a few questions related to it.

  (a) since both of our primary & Eve is going to be in the same data center with good connectivity. Can I assume that although Data guard is more DR solution, in our case it would be HA solution since we have no network latency.

  (b) is it safe to assume that where primary fails, then the day before can automatically take the role of primary education without any manual intervention, possibly using Dataguard broker?

  (c) so I understand that where primary breaks down, the existing connections transfer automatically from primary to standby db (most recent primary), but how my web based java application will know that more recent connections must be sent to the standby db Server (more recent primary)? I guess net Oracle has a provision to handle this? Who can be automated?

  (d) given that I have only 2 physical servers, can I deploy broker Dataguard on a normal PC (since it is a thin client) assuming the PC is kept in the data center and is online 24/7?

  (e) I was reading about the modes of Protection, account required to our current situation & infrastructure, I choose 'Maximum availability Mode' instead of 'maximum Performance '.

  (f) what is your point of view about Oracle integrated security? I hear too much on Oracle failsafe, because people generally go to a combination of CARS & dataguard for HA? We have a few additional storage that can be shared between the two servers, but I feel with literally no DG network latency can provide us HA.

  Concerning

  Learner

  (a) since both of our main & secondary is going to be in the same data center with good connectivity. Can I assume that although Data guard is more DR solution, in our case it would be HA solution since we have no network latency.

  Well it will not provide the level of HA that is RAC. RAC is a Transparent Application failover. With a physical standby, you need to apply some delay for a failover operation. You can implement the observer that can automate the failover and reduce the time.

  (b) is it safe to assume that where primary fails, then the day before can automatically take the role of primary education without any manual intervention, possibly using Dataguard broker?

  This isn't really the DG broker, but rather the observer you will need to implement. The DG broker automate failover. It will be the observer who "sees" (where its name) that the principal is down and initiate the failover process. To do this, the observer will use the DG broker, so it will be necessary.

  (c) so I understand that where primary breaks down, the existing connections transfer automatically from primary to standby db (most recent primary), but how my web based java application will know that more recent connections must be sent to the standby db Server (more recent primary)? I guess net Oracle has a provision to handle this? Who can be automated?

  You'll want to read on the QuickStart failover. http://www.Oracle.com/technetwork/articles/smiley-fsfo-084973.html

  (d) given that I have only 2 physical servers, can I deploy broker Dataguard on a normal PC (since it is a thin client) assuming the PC is kept in the data center and is online 24/7?

  The DG broker is required to run on the database server. The DG broker will run on the primary and standby. I think that what you're asking really anything is if the observer can run on a PC. Yes it can. However, it is probably not a good idea. A PC will not have the internal hardware redundancy, a server can have. If the PC can fail more often than to a server. And if the gods are bad, it will fail when you most need.

  (e) I was reading about the modes of Protection, account required to our current scenario & infrastructure, I choose 'Maximum availability Mode' instead of 'maximum Performance '.

  Your choice should depend on the amount of data loss is acceptable.

  (f) what is your point of view about Oracle integrated security? I hear too much on Oracle failsafe, because people generally go to a combination of CARS & dataguard for HA? We have a few additional storage that can be shared between the two servers, but I feel with literally no DG network latency can provide us HA.

  Oracle integrated security only works on Windows with a MS Failover Cluster. Real DBAs do not have Oracle on MSFC.

  See you soon,.

• DataGuard failover data global or normal service?

  Hello

  I'll put up two rac clusters of 2 nodes using linix and Oracle 12.1.0.2 rh6.

  Clus-1 is the primary db dnt5a and clus-2 it is standby dnt5astdby. between them is a DataGuard broker.
  It is an active-passive cluster.

  What I want is an automatic failover from the primary database to standby db - transperant to the client application.

  This will be possible when it is an active cluster / liabilities?

  The Global Data Service will do or is the Fast-Start-switch function in the best DataGuard soluition?

  Kind regards

  Jan

  Global data service is not running transition real role. Once the transition from role was made manually or by using DGBROKER, the SERVICE is redirected to the specific instance. In the previous version, had to use a combination of GRID infrastructure, DATAGUARD BROKER service to perform this operation. Now using GDS should the Service must be defined and GDS to install.

• Most of DG broker commonly used functions

  DB version: 11.2.0.4

  Platform OS: RHEL 6.5

  Most of our DBs in Dataguard is in 3 CARS (Both primary and Standby) physical node

  Although I worked with dataguard for awhile I never used DataGuard broker. I know you use DG broker to have accelerated failover functionality. But we do not use it in our shop.

  I just want to know what the most common uses of DG broker (other than Fast Start Fail over). I guess it varies from store to store

  Hello

  In my opinion, DG broker is very useful in failover and failover operations.

  It is easier to do from a console one and only command (database failover to XXXX)

  other then connect to primary and standby and run command by command.

  I use also broker set up DataGuard when I have my database ready to go standby. It is even easier for the manual or the execution of the script.

• Passage of Oracle Dataguard and DNS

  Hi, a few days ago, we planned a passage in a configuration of 10g dataguard (dataguard pasive) between the 2 servers.

  primary: Europe.com APP

  secondary: APP1 in Asia.com

  The two databases was Oracle 10.2.0.3 in Redhat (single instance)

  Everything is going well with databases and the digital switchover but what happened with the web-based applications?

  I have a lot of web PHP applicattion provided with a string of connection with OIC and oracle customer, all have the connection as user/pass@dbname where dbname is defined in the local tnsnames.ora with DNS host names.

  (All have xxx/xxx@APP), and was APP (host:europe.com and SID = APP)

  Europe.com was ip 1.1.1.1

  Asia.com has been ip 2.2.2.2

  My primary instance was APP (name sid) and the standby APP1 (name sid) but what happened when I pass the dataguard?

  Yes, because we have a lot of requests and we don t change the connection string, each of them tries to connect to the new basis of Eve physics APP which is in Europe.com. (and the main news is APP1 in Asia.com)

  Well, first of all, I must change the SID in the database (same as the primary database) waiting for the connection string, for which I have: (thus development are don't want to change the string of connection...)

  (1) immediate stop aid database

  (2) remove the dataguard broker configuration,

  (3) change the instance name in the spfile APP1 to APP.

  (4) change the name of db in the spfile APP1 to APP.

  (5) change the setting fal_client (INSTANCE_NAME = APP1) to (INSTANCE_NAME = APP)

  (6) change the app APP1 orapwd file

  (7) Exchange configuration bash_profile APP and re start the database pending.

  (8) check the listener.ora, so that the new listening service is APP and no APP1

  (8) with respect to the dataguard broker configuration config

  OK, everything works very well and we have the main and the database pending with the same SID.

  But what happened with the dns servers? because the web-based applications will try to connect to APP but APP has been defined as Europe.com and I want to redirect Asia.com as primary database.

  Well, first of all, I changed all my settings and broker dataguard over IP and not dns configuration files, so I made a guide to procedure for the passage to the then when we said that, first we must transition to digital, data bases and then the surface NET must change the DNS for new Europe.com dns point to 2.2.2.2 ip

  After that, everything works great!

  So in conclusion, to forward a permutation with dataguard (which was an excellent feature) check the connection of the chain of applications and take care of them) and if necessary, use the same SID for the two (databases) and emergency

  (In Oracle 12 c, we have a lot of thing to use as a continuation of the app for that)

  Kind regards

  Hernan

  Hi Herman,.

  Maybe I'm mistaken, please correct me if this is the case.

  Assuming you are using oracle customer why not just use the construction in the mechanism for this purpose? DNS has nothing to do with it, but I see people using it yet for this - it is not only suitable for failovers, I do not have my TTL of 60 seconds or less to my recordings of A.

  I had a project for banking HA where after permutation is launched the application (Tomcat) could in a minute to connect automatically to the database of watch on the Internet. First, you must use the database instead of SID service, so you can have the same service on the previous day. What more have a service, you can be sure that it will run the day before until it becomes primary, otherwise you can find yourself in a funny situation. Secondly, why not using built in failover of the connection string parameter, this way you can queue db (s) and in the case where your primary does not that the oracle client will simply try to connect to the waiting (to search for the same service). To ensure that the standby database does not have the service at any time, you can deploy trigger (AFTER startup) to check the role of database, if it is 'primary' it starts just the database service.

  Kind regards
