• RAC and Data Guard

  I just want to know if my main site's CAR and I want to set up a physical standby site using Data Guard; the backup site must be in configuration CARS as well, or can it be a stand alone configuration?

  Hey Buddy,

  I just want to know if my main site's CAR and I want to set up a physical standby site using Data Guard; > the backup site must be in configuration CARS as well or can it be a stand alone configuration?

  No, it is not mandatory. You can set up a watch using one instance and the database with the help of a RAC. as well as the opposite.

  For example, I've already migrated a RAC to a single instance, using stand-by. Rather than perform a failover, we performed a switchove, then the database primary was a single instance and the day before by a RAC database.

• 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.

• TopLink grid 11g and data consistency affinity

  I am to evaluate TopLink 11g grid that fits the coherence data grid. It seems to me when TopLink routes the request of coherence, it converts primary keys of database to be the key used in cache coherence. Is it possible to customize this conversion? The reason is that we want to use the affinity of data coherence function that requires a key to consistency to implement the method to return the keys association and lead conversion does not work for us.
  
  Thank you very much!

  I advise to use an IdClass incorporated into your JPA entities. You can then implement the necessary logic on the IdClass.

• When creating Data Guard?

  We intend to migrate a database RAC and Data Guard.
  
  When you recommend implementation of custody of data? Before the export/import (from the old server to new CARS in custody of data) or after?

  You must first configure your new primary CARS and then configure the standby of the CARS (after the imp on the primary).
  This way you avoid the mass mailing to redo the expectation that comes with the PMI, if this sequence of steps will be faster.

  Disadvantage: If you take the primary CARS into production immediately after importation, there will be a short period of time without protection in this way DR.

• Oracle 10g RAC + ASM + Data Guard: Question on the new disk group.

  Hello
  
  One of our clients is to have Oracle 10 g RAC + ASM + Data Guard. Database is the disk DATA_DG1 group and FRA is on FLASH_DG1. Data Guard is a single instance on ASM.
  
  To add more space, we can create another disc of the Group DATA_DG2 on Prod ASM and Data Guard ASM env, replication continues without any problem. Will be archiving logs shipped to the second disk DATA_DG2 group and applied without any configuration changes?
  
  Rgds,

  Yes, it sounds great.

  You should be fine with the implementation of these measures and the dataguard should continue on as usual.

  Just make sure that you are dealing with a physical standby that has not the conerts file name defined.

• 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.

  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.

• Grid d? infrastructure is needed for Active Data Guard fast failover?

  Hello

  I'm currently deploying an Active Data Guard of 11 GR 2 configuration with a captain and two slaves physical standby and failover accelerated for a Java JDBC application. Each instance has a read-only service that is always active and a service of reading / writing that is activated only on the master:

  srvctl add service -d smsgsig1 -s smsgro -l PRIMARY,PHYSICAL_STANDBY -e NONE -m NONE
  srvctl add service -d smsgsig1 -s smsgrw -l PRIMARY -e SELECT -m BASIC -w 10 -z 150
  

  Initially, I had planned to use the Service of Notification of Oracle (ONS) to notify the application in case of change of master, that works, however, after a few tests, it seems that simply leave the retry request enough times in the case of a connection failure is sufficient to re-connect to the new master afterwards, in order to complete any pending transaction.

  So my question is: since I plan not to use ADD-ONS, do I have the grid infrastructure and Oracle Restart at all to deploy Active Data Guard? The documentation does not explicitly require it, and all the necessary tools, including srvctl, exist in the plain 11 GR 2 home. However the mechanism of activation/deactivation of the service will work without restart? To be honest, I don't think it would be, but that this would simplify the deployment, a little, I thought it would be good to ask :-)

  Thank you for your understanding,

  Chris

  Hello;

  The simple answer is no, I could consider changing my order srvctl.

  EI SESSION (type switching must be set to both)

  m BASIC (set on both)

  l PHYSICAL_STANDBY (isn't one of yours in this service role?)
  z - 15 (150 retrys seems too high)

  q (the value TRUE or FALSE)

  w (set on both)

  srvctl add service d smsgsig1 s smsgro-l PRIMARY - SESSION - q TRUE m BASE w 10 EZ 15

  srvctl add service d smsgsig1 s smsgrw-l PHYSICAL_STANDBY - q REAL - m BASE w 10 EZ 15 SESSION

  How can we know what newspaper Archives are eligible to be removed from 'A' and 'C '?
  When remove it takes place?
  How can say us when archiving logs are deleted from the 'A' and 'C '?

  Dear user10260925,

  The documentation that you read is reliable but not enough.

  The Oracle can handle the archivelog directory and know that you are eligible for deletion. Stuff you posted here was derived from the books online and is supported and can be used when the Oracle knows and manages the archivelogs. This is simply called the flash recovery area. Please read the FRA at this very moment.

  Under the personal component normal circumstances in the industry use a few scripts to achieve on backup archivelog deletion.

  Here's a useful example to you;

  # Remove old archivelogs

• Active Data Guard and Undo and ora-01555

  Hello
  
  We have a 11.1.0.7 two nodes primary CARS with a physical standby single instance Active Data Guard. When you run an export datapump since the day before, we get an ORA-01555 while the undo_retention is well beyond the duration of watering for export.
  
  I'm looking to better understand the cancellation as part of Active Data Guard. Is there any dependency for cancellation between the primary (s) and the day before? Are the settings Cancel (undo_retention, tablespace... undo size) on the primary and independent intelligence on the other?
  
  Thank you.

  The wait is a physical expectation. An exact copy of the primary. The cancellation to sleep is controlled by it again come from the primary. When the cancellation is replaced in the primary, he gets crushed to the standby regardless of what it executes. You cannot cancel maintained around more on the eve, it is a replica of the primary.

  Increasing the undo tablespace and the primary undo_retention allows more Cancel to keep both primary and standby, but Eve is always controlled by the direction of the primary to cancel it. Of course, you must change the setting to sleep too so that everything is the same when you made the day before to a primary database.

  I hope this helps.

• motion control for vertical actuator and data acquisition

  Hello

  I am a researcher (a branch of civil engineering) geotechnical engineering and I have very little knowledge about the acquisition of control and data motion, so would need a lot of help from the experts OR. I have only knowledge base on these 2 aspects based on my reading of some materials on the Web site of NOR and youtube videos, so I hope that you bare with me . Here are my questions:

  I am trying to build an actuator which will be used to push a probe (a penetrometer with a load cell to measure the resistance of a soil sample), resembling the concept, photography in the attached file. I need to have these criteria for my system:

  (1) actuator, which can push the probe at speeds between 0.01 mm/s - 300 mm/s with precision and move the probe cyclically (upwards and downwards) in the vertical direction
  (2) load expected on the probe into the ground range: 0.02kN - 6 kN.
  (3) necessary to get the load cell load data and the speed of the probe.

  4) able to control the actuator to a PC (speed and posotion) and monitor data from transducers and data log time even the transducers.

  Guess my beginners is that I will need:

  For orders:
  (1) software - LabVIEW and NOR-motion assistant

  (2) controller - NI PCI-7342

  (3) driver/amplifier - analogue servo AKD Drive

  (4) motor - motor brushless servo AKM

  For the acquisition:
  (1) software - based LabVIEW development systems

  (2) amplifiers or other device - no idea what type on the conditioning of signals

  (3) data acquisition device - no idea what type

  Since I'm a beginner, is - that someone might recommend components (hardware and software) for the control and data acquisition. I'm on a tight budget, so I thankful if someone could help me to recommend components good enough to build my system.

  Thanks for your help.

  At these rates, you will need to run the sensor for the cDAQ.  You can configure the analog output on the Tritex nationally on the position.  There is an adjustable filter that you can set in order to get a clean enough to 300 Hz signal.  When you learn about the Tritex, make sure that let you them know what comms and e/s that you want to use.  If I remember, not all options have worked together.  The analog output may need to be my, but you can put a resistance through the acquisition of input data to get the voltage instead.  I don't remember all the details.  You should really not too much on the Tritex/LabVIEW side.  You will send your movement parameters (beginning of end of race, speed, position, accel, cut), and if you cycle (I believe you) or simply running in a loop.  You could also just be able to use the functions of jog.  When you get close to knowing exaclty what you need, PM me and I'm sure we can work something out with the drivers.  You need only the basics.  In fact, you could probably do this all your movements via digital and analog i/o.

• Data Guard - allocation of licenses and other fundamental questions before setting it up.

  Hi all

  Please allow me to submit some questions about Oracle Data Guard.

  There are 2 databases 'authorized and ready ':

  -a single instance of the "alfa", Oracle Enterprise Edition 10.2 database,

  -"bravo", Oracle 10.2 Enterprise Edition, Real Application Clusters database

  I have to "align" congratulations to alfa on a daily basis, so that--in case of failure of the main 'alfa' site - recovery is possible change to the site "bravo."

  (1) even if we can afford a loss of data corresponding to the period little uttered at the end of the last daily alignment (no need to 'transactional' alignment between the two databases), I assume that the best approach to meet this need in terms of efficiency and manageability consists on two databases including in a Data Guard configuration.

  Am I wrong?

  (2) in particular, the physical implementation of the standby database must be preferred over logic, because that "simpler and faster" in this case. Am I wrong?

  (3) only the Data Guard configuration require

  (a) additional licenses?

  (b) additional material/software resources for host machines?

  (5) the release of two databases must be equal to the specific to the component version number (10.2.0.1, for example)? Or, for example, is a 10.2.0.1 able to work with a 10.2.0.3 db db in the Data Guard configuration?

  Thank you very much in advance!

  Am I wrong?

  You have reason, physical hosting it good thing. For the most part, you will get impact with until or unless data loss because of some problems of network (or a configuration problem)

  (2) in particular, the physical implementation of the standby database must be preferred over logic, because that "simpler and faster" in this case. Am I wrong?

  Logical standby is a little different from the physical standby mode

  (3) only the Data Guard configuration require

  (a) additional licenses?

  (b) additional material/software resources for host machines?

  Data features come with Enterprise Edition - perhaps for the active database "cost of the additional license.

  https://docs.Oracle.com/CD/E11882_01/license.112/e47877/editions.htm#DBLIC109

  Good level to maintain the same level of oracle binaries / patches and still the support of heterogeneous DG
