• Logs archiving for the RAC ASM basics

  Hello
  
  I have a question about logs archiving on the ASM database located on a RAC. I created a database orcl who has orcl1 instance on node1 and orcl2 on Node2. For the backup of this database, I enabled for the database to archivelog.
  
  After a few transactions and backups, I noticed that there are two sets of archiving logs created on each node in the folder $ORACLE_HOME/dbs. In node 1, it starts with arch1_ * and node2 is arch2_ *.
  
  IWhy is it creates logs archiving on local disks, in which she should ideally create disks asm which is shared between the nodes. My backup application fails with journal archive not found error, because it searches newspaper archives in the other node.
  
  All entries on this will be useful.

  Hello

  I have a question about logs archiving on the ASM database located on a RAC. I created a database orcl who has orcl1 instance on node1 and orcl2 on Node2. For the backup of this database, I enabled for the database to archivelog.

  After a few transactions and backups, I noticed that there are two sets of archiving logs created on each node in the folder $ORACLE_HOME/dbs. In node 1, it starts with arch1_ * and node2 is arch2_ *.

  I believe that it is missing from your configuration database and Oracle uses the default location. (i.e. your "$ORACLE_HOME/dbs")

  ARCHIVELOG must focus on a shared domain.

  You need the parameter config below:

  SQL> show parameter db_recovery_file
  NAME                                 TYPE        VALUE
  ------------------------------------ ----------- ------------------------------
  db_recovery_file_dest                string
  db_recovery_file_dest_size           big integer 
  

  Or location of default config:

  SQL> show parameter log_archive_dest
  
  NAME                                 TYPE        VALUE
  ------------------------------------ ----------- ------------------------------
  log_archive_dest                     string
  

  IWhy is it creates logs archiving on local disks, in which she should ideally create disks asm which is shared between the nodes. My backup application fails with journal archive not found error, because it searches newspaper archives in the other node.

  To resolve this problem see this example:

  SQL> show parameter recover

• 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

  mseberg

  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.

• RMAN-08137: WARNING: log archived not deleted, necessary for intelligence or upstream collection procedure

  Hi Oracle Community,

  I have a few databases (11.2.0.4 POWER 2 block and 12.1.0.2) with Data Guard. Back up this database with RMAN to ribbons, only on the primaries.

  During the backup, sometimes I got RMAN-08137: WARNING: log archived not deleted, necessary for intelligence or upstream collection procedure

  By reason of this global warning to backup status is "COMPLETED WITH WARNINGS". Is it possible to remove this warning, or perhaps change RMAN configuration to avoid the appearance of this warning?

  Concerning

  J

  Where is the problem on these warnings? If you do not want to see such warnings, why not simply to perform the removal of the archivelogs in a separate step? For example:

  RMAN> backup database plus archivelog;
  RMAN> delete noprompt archivelog all completed before 'sysdate-1';
  

• Need help on design for 2 EBS with RAC environment

  Hi all

  We currently have 4 servers with 256 GB of RAM, 1 TB HDD and 8 cores. Our requirement is to configure two EBS 12.1.3 with DB RAC environment. We want to take advantage of these 4 server to accommodate the two EBS since the configuration of the server (application server 2 with HA and 2 DB for RAC servers) are quite high, because the concurrent users on each EBS are not more than 200.

  So our problem is as below:

  Say we have these server 4A, B, C and D. We have 1 create multi instance node, with DB on server A & B (CARS) and application on the server C & D. Now if we want to install the second case, with the same architecture on the same servers that we do.

  (1) use the same grid infrastructure and create DB for 2nd instance cluster even. (how?)

  (2) install another grid infrastructure and create totally another cluster for this instance.

  You can do the following for a case of BSE, and perform similar operations for a 2nd on the same grid. Check after the link. He detailed information EBS on RAC Setup

  Install EBS R12 on 11g RAC Oracle ASM

  
  

  High level steps are:

  
  

  • Install and Configure Grid Infrastructure on cluster 2 nodes.
  • Create the DATA starts EAM and FRA with a sufficient size.
  • Install theSoftware to the database of this Cluster Homeon.
  • Install the EBS by using a quick installation on the database node 1 (out of the BOX Non-RAC on 1 node installation
  • Install BSE using rapid installation on nodes of applications.
  • Convert the database of 11 GR 1 material not RAC RAC Database.

• "DAQmx Configure Logging" found in Labview 2009

  Dear Sir or Madam

  I have the version of Labview 9.0f3 instored. Measurement & Automation Explorer version 4.60f1 instored.

  Must I update anything to run the attached VI?

  Problem:

  As mentioned in the file like this http://zone.ni.com/devzone/cda/tut/p/id/9574

  "NOR-DAQmx 9.0 installs a new DAQmx Configure Logging VI VI". However, I can't find this VI in my control panel and the icon appears as a question mark.

  

  There are two ways to check your version of DAQmx:

  (1) measurement and automation explore:

  

  (2) using Add Remove programs

             

  My guess is that you use DAQmx 8.9.5 and need to upgrade to 9.0 or later.

• Linear encoder and configure logging

  Hi all

  I am currently using a surfboard with LV2010 M Series PCI-6280.

  I have a linear encoder in X 4 mode connected to the counter 0 and I was wondering if it is possible to spread the values on the counter because it keeps track of the distance in a file TDMS using 'DAQmx Configure Logging'.  I tried this using MAX to set this, but it doesn't seem to work, so I wonder if it is still possible that I couldn't find anything online about it.

  Thank you

  Lester

  Hi Lester,.

  My apologies, I tried on another Committee. It can work with yours, as well. There is an example of a task of counter in the buffer that should allow you to save the data by adding in the Configure logging VI as we did before.

  Open LabVIEW and select help > find examples... it will open the Finder of the example. In the Finder of the example, expand folders to get to the input and output material > DAQmx > Counter measures > County Digital events > County Digital events-buffer-meter-Ext Clk.vi

  Put the meter right channel and channel PFI in the controls, and then run the VI to see what he does. Then you can change the schema to add the configuration Logging VI (just as before) and rerun the VI. You will find yourself with a TDMS log saved to the path that wire you in the logging VI configures.

  I hope this helps.

  Kind regards

• major differences of exadata database, listener, process than the normal RAC environment?

  I would ask for any input about the major differences of exadata database, listener, process than the normal RAC environment.

  I know now the exadata have not only SCAN listeners, but many other listeners. expert here can provide clarification?

  Thank you

  All the right questions... Welcome to the world of Exadata.

  These are questions that could get into a lot more detail and discussion than a forum post. At a high level, you certainly don't want delete all indexes on Exadata. However, you need to index and an indexing strategy will change on Exadata. After you move a database from one not Exadata Exadata environment you are probably more indexed. Indexes used for OLTP transactions real - looking one or a few lines among others will usually quickly with an index. The index used to avoid a percentage of records but always returning number of records can often be moved. On the index depends on the nature of the workload and your application. If you have a control on the index, then test your queries and DML with the index (s) invisible. Check your implementation plan, the columns io_cell_offload in v$ sql, smart scan wait events to ensure you get intelligent analysis... and see if the smart scan is faster than using the index (s). The real-time SQL Monitor is an excellent tool to help with this - use dbms_sqltune or grid/cloud control.

  Parallelism is a great tool to help still speed up queries and direct path loading operations and can help prompt smart scans... but use of parallelism really depends on your workload and must be controlled using DBRM and the parallel init parms, possibly using same parallel declaration put on hold, so it is not overwhelm your system and cause concurrency problems.

  If you have a mixed environment of workload or consolidates databases on Exadata so my opinion is IORM plans should certainly be implemented.

• Concept on Undo tablespace in RAC environment

  Why we need two different Undo tablespace for two different instances in RAC environment. What are the internal mechanisms behind it? No explanation of the concept will be great for me. What will be the scenario if we have same tablespace undo for two instances?

  Thanks in advance.

  Hello

  To reduce CONTENTION and the complexity of the software.aslo oracle instances share not undo tablespace using cancel separate increase the availability of data undo files.

  Note: all instances can still read that cancel all blocks for coherent reading purposes. In addition, any instance can update the any tablespace undo during the restoration of the transaction,

  as long as undo tablespace is not currently used by another instance to cancel generation or a recovery operation.

• Size of the huge log archive

  I have 5 redo log files. Each is 4 GB. There are huge transactions (1800-2000 per second). So we have every hour 5-6 journal of the switches. So all the hours of archives journal 20 to 24 GB and daily increase in size, the size 480 GB.
  
  I had planned to take an incremental backup of level 1 and level 0 per week daily with the option delete log archiving 'sysdate-1 '.
  
  But we have little storage if, it is impossible to the sphere 480 GB per day and take backup of these 480 GB for 7 days (480 * 7) GB = 4 TB. How can I correct this situation? Help, please.

  1 disk is cheap
  2 the onus on those who "Advanced" application
  3 you can use Log Miner to check what is happening.

  You need to this address with application developers and/or clients and/or buy the disc.
  There are no other solutions.
