• What is the effective available disk space in exadata

  Hello
  Greetings of the day,
  
  
  Is below correct understanding?
  
  
  There are 7 items in a machine half rack and are all copies mirror of the other, if the effective storage space = space in a single cell.
  
  Even if we have a normal redundancy in each cell, then effective the whole exadata storage space will be half of the disk space in the cell.
  
  
  Is there a rule that all cells must have equal disk space?
  
  
  From the perspective of the DSO.
  
  Is there a rule like all the all fails it (2 or 3 depending on the level of redundancy) groups must be of equal size with a disk group?

• Exadata characteristic and execution of study plan

  Hi all
  
  I have questions about Exadata functionality.
  We have meet a performance problem in the current system and to improve the system. We are studying how much benefits that Exadata can give.
  After reviewing the daily execution of the SQL statement, we find that there is certain amount of "index range scan", operation "index full scan" (from execution plan). Exadata helps these operation (e.g. smart scan)? On the other hand, it is that all execute SQL (for example the full table scan) can be advantage in using Exadata?
  
  Thank you and best regards,

  Dear christian Christmas Pal Singh,

  Thanks for your information.
  Currently, the SPA is not available for evulation. It is any document describe what type of operation (e.g. Index scan interval, scan of table full) Exadata eligible in terms of performance?

  Kind regards

  Yes, you can have simulation setting CELL_OFFLOAD_PLAN_DISPLAY to always. With this setting at the level of the session we could see change explain the plan, such as optimizer would think exadata is available.

  Please note that oracle would not recommend to use/infact analyzes all your indexes in Exadata, because by FTS is much more effective in Exadata. Once you have moved your application to Exadata, you apply main index in INVISIBLE mode and the benefits you get (there would be huge :)).

• Refresh your EBS 11i to R12 on Solaris 10.

  Hi all,

  My environment is to have DB-9.2.0.8.0/R11.5.10.2.0 on Solaris 10 - 64 bit.

  You will need to update to DB-11.2.0.3.0/R12.1.3.

  My plan is to upgrade of Database 9i to 11 GR 2 directly according to the following documents of the oracle portal.

  Interoperability Notes Oracle EBS 11i with Oracle Database 11 g 2 (11.2.0).) (Doc ID 881505.1()

  Refresh your application 11i to R12 according to the below documents oracle portal.

  Guidelines for preparation of databases for an upgrade of the E-Business Suite 12.1 output (Doc ID 761570.1()

  Oracle E - Business Suite Guide upgrade: Version 11i release 12.1.1, part number E14010-01

  I can able to upgrade DB from 9i to 11 GR 2 directly, which will create 11 GR 2 oracle_home, even while improving 11i to R12, it will create 11 GR 1 material oracle_home. Which the database oracle_home, that should be used to upgrade R12?

  Thank you and best regards,

  Smocky

  My question is what oracle_home of database we must consider to upgrade R12? and what about another an oracle_home?

  When you run a quick installation, please provide details of the 11.2.0.3 already set to day/install ORACLE_HOME.

  For 11 GR 1 ORACLE_HOME material that is installed by a quick installation, please see (how upgrade Oracle E-Business Suite 11i 12.1.1 to and keep the existing Database 10 g? (Doc ID 1345020.1)).

• Exadata general patching question

  Hello.

  We currently have many 11 GR 2 (11.2.0.3). DBs (CAR & no RAC) running on different platforms RHEL and Solaris.  We have recently acquired both full quarter RACK Exadata X 3 machines.  "Due to limitations, these X3s are no gateways installed to ' auto-patching", then we will do it ourselves.  In the past, we have always exercised quarterly processors (compared to power supply).  Aside from the issue of the PSU against CPU (my management has buy in approach of power supply of 100% - I have already recommended), I have the following question.  With Exadata, I'll still be able to apply only the central units or I have to go immediately to the application of power supplies.  Wqay one or another ask can you still apply just to processors to Exadata (server, storage, etc.)?  Thank you.

  Hi Matt,

  I have only applied patches full bundle and never did a partial correction of the WAD.

  The Readme file that accompanies the patch bundle doesn't explain how to apply the complete bundle as well.

  The concept of engineered systems should have standardized levels of patch on a basic installation of the software for ease of support.

  I fear that Oracle do not offer you the choice in bundle packs.

  Kind regards

• 10.2.0.4 to 11.2.0.1 reclassification; a fundamental question about ORACLE_HOME

  Operating system: Solaris 5.10
  
  I did only the updates of the Group of hotfixes. It is the first time that I do a upgrade version to another.
  
  That's what I heard in ID 429825.1.
  
  To upgrade a 10.2.0.4 DB to 11.2.0.1
  
  Step 1. Install 11.2.0.1 (software only) in a separate House
  
  If my current 10.2.0.4 ORACLE_HOME is /u01/app/oracle/product/10.2.0/db
  then install 11.2.0.1 software in /u01/app/oracle/product/11.2.0/db
  
  Step 2. Run utlu112i.sql and solve all the problem mentioned in the output
  
  Step 3. Stop the db 10g
  
  Step 4. Copy the new file inti.ora with the new 11g setting in the ORACLE_HOME/dbs 11.2
  
  Step 6. Set ORACLE_HOME as a new ORACLE_HOME 11.2
  
  Step 7. set the ORACLE_SID for 10g DB and starts in UPGRADE mode

  startup upgrade pfile=11g_R2HOME/dbs/init.ora

  8. Run 11gR2_home/rdbms/admin/catupgrd.sql
  
  
  My question concerns step 6. How can you start a 10.2.0.4 DB after you set the ORACLE_HOME a 11.2 House?

  The previous poster, exactly gave you the best recommendations.
  regarding your question on step 6 (maybe 7 or you meant) so the answer is that you start up using 'upgrade', not normal mode. You are starting/editing the 'old' database of version under the new oracle_home/binary software and do the scripts (catupgrd.sql) special to upgrade the database itself. Saying in other words, start upgrade is not startup, it opens a database in a special mode

• Client Oracle / 10 g ORACLE_HOME / very basic Question

  Hi all
  
  I am a little bit confused about something for installating the Oracle DB and his Client on the same computer, Windows (Vista Business, 32-bit).
  
  In the release notes, it is said (4.3), you can install the Oracle Client in the House of the same version as the database.
  In the installation instructions, it is said, • "You must install the Oracle database Client in a new Oracle Directory." (Article 3).
  
  FIRST QUESTION: OK even if the notes of publication wins installation, I'm assuming (am I right here?) you CAN install the client in a separate House?
  
  During the installation of the database, there is an instruction to create the ORACLE_HOME environment variable. This is repeated in the installation of the hotfix. When I installed the client - in a separate House - UI deleted environment variable because "is not necessary for all Oracle products."
  (I realized after the fact that the installation of the database and the client before installing the patch would have been better.) SO-
  
  SECOND QUESTION: Should I create the ORACLE_HOME environment variable. and if so, for which the House, when I install the patch for the customer?
  
  Thank you
  
  Edited by: DonnaF May 21, 2009 10:50

  When you install the client, yes it's true, it must be installed in a separate Oracle home. The only reason why I found to justify the installation of Oracle client under the same roof of Oracle RDBMS is due to the availability of administrative tools. In previous versions (9iR2) when the installation took place he installed Oracle Enterprise Manager as well as the RDBMS Oracle Home. From 10 gR 1, Oracle Enterprise Manager (thick java client) is no longer installed with the database, but if you need to install it, you need not create a separate Oracle home.

  Now why you want to install the OEM heavy customer when DBControl EM is available in 10g? The reason because if you want to use Oracle streams, those can not be set in EM DB control, as well as the for replication option, it is not available in EM DB control. So you will need to install the client. One more reason? If you ever plan to set up Enterprise User Security and virtual private database, then will need you the tools to manage the E.U.S. and the OPM (Oracle Policy Manager). Those that are available only in java heavy client mode.

  So, if you don't need these administration tools, and you don't plan to use, you can perfectly live with the RDBMS as is.

• ORA_CRS_HOME, ORACLE_HOME and ORACLE_BASE - newbie question

  Hi all
  
  I am trying to package for Oracle logs according to the DOC ID ID 330358.1. There it says I need set the variables listed (I use Windows). I use 11 GR 2 and I was wondering if anyone would be able to confirm what I think are below:
  
  ORACLE_HOME - E:\app\oracle\product\11.2.0\dbhome_1
  ORACLE_BASE - E:\app\oracle
  ORA_CRS_HOME - now, I have the grid installed in a separate folder, so I think it's E:\OraGrid\crs, but I may be wrong

• The ASM diskgroup in exadata space question

  All,
  
  I have an environment exadata 1 CCR node with 3 knots of strorage.
  
  My RECO ASM diskgroup is constantly showing the problems of space... Always higher than 80%.
  
  I just want to get a Board if I can remove mirroring and recover the space... Even though I know that the result of the deletion of the mirroring...
  
  Can I reduce the diskgroup RECO and create an another diskgroup?
  
  I want just a few ideas to do this without great risk involved...

  You may want to consider these MOS notes for more information on resizing the griddisks:
  Resize diskgroup without downtime to Exadata (Doc ID 1272569.1)
  How to resize the disk drive/grid ASM in environment Exadata (Doc ID 1245494.1)

  As others have mentioned, there is no way to change the level of redundancy in ASM, so you need to delete and re-create the diskgroup if you want to change to redundancy. We strongly discourage the use of EXTERNAL with Exadata redundancy.

  And I bet this isn't because you have never successfully configured your dbcontrol.

• Datapatch on the new empty container (CBD, exadata 12.1.0.2) database returns the error state of the PDB.

  I created a new CBD CAR empty database on a cluster exadata using an ORACLE_HOME (12.1.0.2) which has been patched with patch latest bundle.

  I ran the datapatch utility to apply these patches to the container before any new APB to a database that is already patched the cloning.

  However, datapatch first correctly identifies adjustments but it fails on a prereq error:

  Unfortunately the MOS score is General and I do not see this situation described. The newspaper simply indicates this same error.

  
  

  Since there is no PDB, why make this mistake?  I don't think it's possible to open the PDB$ SEEDS as upgrade?

  
  

  I had already tried cloning my non - PDB in a PDB here (successfully) file, but then I also met problems with datapatch (in PDB not at CDB patch).  I tried with the options and force database and this succeeded with warnings, but I was unable to open the PDB.  I thought, okay, what oracle says that the whole point of multitenant is to be able to update the plugin, it should be possible to patch a CBD empty.  I can't seem to find much on this point, somebody manage this problem?

  
  

  What is the best method to establish the original CDB and ensure that it is patched in line with its ORACLE_HOME?

• Is it necessary to have Oracle_Home Windows

  My environment: Oracle 12 c on Windows 2012 R2 server standard.

  I have not yet put ORACLE_HOME and ORACLE_BASE environment variables. But I do not see the registry keys under HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_OraDB12_HOME1 ORACLE_HOME and ORACLE_BASE.

  My question: is it necessary to have created too much environmental variables? What Oracle utility or application component uses these environmental variables?

  Laughing out loud

  Oracle has a hierarchy, it follows for the resolution of the environments.  For windows, it makes sense to use the registry.  Exactly how to change things, like when you have multiple oracle homes, varies according to the version and tools.  For example, there are a snap to the for Oracle administration microsoft management console.  Somewhere this hierarchy is documented, I don't have time to find all the time.  I have not worked with 12 c, so it could be something different, get the docs.

  In other cases, such as the instant client, you can just set the system environment variables and the path.  In other cases, you might want to put in place a batch file defining the variables.

• RTO in Exadata

  I have a few questions on OTN, please help.

  • for the 2 TB database, what is the objective of minimum possible recovery (RTO) for the X 5 - 2 Exadata quarter rack?

  • What are the ways to reduce the OTR?
  • How long it is necessary to perform a full restore of database 2 TB quarter rack?

  Aerts

  Abhi-

  Here are my best attempts to answer your questions:

  • for the 2 TB database, what is the objective of minimum possible recovery (RTO) for the X 5 - 2 Exadata quarter rack?
    • There are so many variables to minimize the resulting RTO of used tools, network, storage, platform, distance/time of latency between physics and sleep, etc., it is difficult to respond to the possible minimum RTO. Theoretically using a solution like Golden Gate in a multi-master (two-way replication active/active) configuration, you may reach an RTO 0. This assumes that your application and database can support such a configuration. A more traditional and less complex DR configuration, using the data guard must be able to measure the RTO in a few minutes.
  • It is possible to get 2 minutes RTO for the 2 TB database running on rack quarter X 5-2?
    • In a real recovery architecture disaster primary/secondary with Exadata, the best solution is Data Guard. If correctly configured and able to minimize latency between main and backup, Server data hold switch or fail should be measured in minutes and should be possible to get almost 2 minutes RTO.
  • What are the ways to reduce the OTR?
    • There are several factors including the adequate capacity of the CPU on source and target, I/O bandwidth and latency, bandwidth and latency that affect the RTO with data protection. Make sure you have sufficient resources and best practices to set up your environment. Some white good reference books Oracle, which include specifications for Exadata, are http://www.oracle.com/technetwork/database/availability/sync-2437177.pdf for the transport of synchronous recovery and http://www.oracle.com/technetwork/database/availability/async-2587521.pdf for transport to asynchronous.
  • How long it is necessary to perform a full restore of database 2 TB quarter rack?
    • Depends on where you are restoring from. We have seen great results in the backup and restore of time using a ZFS storage device connected via Infiniband Exadata. With 2 controller 4 disc tray configuration we were able to restore a database of 2 TB in just 8 minutes.

  select 'export NLS_LANG='||p1.value||'_'||p2.value||'.'||p3.value NLS_LANG from nls_database_parameters p1, nls_database_parameters p2, nls_database_parameters p3
  where p1.parameter = 'NLS_LANGUAGE' and p2.parameter = 'NLS_TERRITORY' and p3.parameter = 'NLS_CHARACTERSET';
  

  Then export NLS_DATE_FORMAT both NLS_LANG on the operating system and run the query again on SQLPLUS.

  Kind regards.
