About CPU/PSU patches

I understand that there are different database CPU/PSU patches for
(1) Grid Infra homes
and
(2) Oracle DB homes.
So are we supposed to apply ONLY "CPU/PSU for Grid Infra" to clusterware homes
and apply ONLY "CPU/PSU for Oracle DB" to Oracle DB homes?
Or
Are we supposed to apply BOTH "CPU/PSU for Grid Infra" and "CPU/PSU for Oracle DB" to clusterware homes and Oracle DB homes?
Thank you in advance.

Your questions are answered in MOS Doc 1339140.1
PSU patches include CPU content, but they employ different patching mechanisms and cannot be interchanged. GI PSU patches include database PSU content and should only be applied to GI Homes. DB PSU patches should only be applied to DB Homes. The directions in the README of any patch should be followed at all times.

  • 10.2.0.4 cpu/psu Patch.

    Hi,
    I have to upgrade the database from 8.1.7.3 to 10.2.0.4.1(Does 10.2.0.4.1 reflects cpu/psu patch status?)
    OS =HP-UNIX 11.11
    Does cpu/psu patch comes along with 10.2.0.4 patchset?What is the best way to upgrade the database?
    Below is the steps what I am thinking to implement:
    (1) apply patchset8.1.7.4 and upgrade database by running catalog.sql and catproc.sql
    (2)Install 10.2.0.1 base version.
    (3)install 10.2.0.4 patchset
    (4)apply cpu/psu patch 10.2.0.4.1
    (5)start up upgrade and run catupgrade.sql for db upgarde?
    Will catupgrade.sql will take care for catcpu.sql?
    Please share your experience with me.
    Regards,
    MK

    You need to read the upgrade docs. What matters is not whether one script runs another ... but rather that if you follow Oracle's directions you will be successful. Which means the correct scripts will be run in the correct order.
    But why are you moving to 10.2.0.4 this late in the game rather than 11.1.0.7 or 11.2.0.1?
    10.2.0.4 is going to be in extended support mode in just a matter of months.

  • Oracle DB CPU/PSU patch released till date

    Hello All,
    Does oracle maintain any kind of spreadsheet that shows all the CPU/PSU patches released by ORACLE till date along with the date and the os it is for.
    Thank you.

    I think you are after this.

  • CPU/PSU Patching through OEM

    hi,
    We have large number of database in our environment. So we planned to do the CPU/PSU patching through OEM.
    So like to know the feasibility of doing from OEM whether we can or not? and is there any other security issue in doing so.
    I mean only with oracle user we can able to do the patching through OEM or we can do with any other user who has privilege.

  • Question about CRS PSU Patch.

    Hello all,
    My customer is currently RAC 10.2.0.4.3 (i.e 10204 patchset + Database PSU Patch 9119284) and with 10.2.0.4 CRS
    Currently due to a CRS Bug we recommended customer to apply CRS PSU 10.2.0.4.4 i.e Patch 9294403
    Now the question is :
    can the customer apply the CRS PSU 10.2.0.4.4 when he is with 10.2.0.4.3 RDBMS PSU ?
    (NOTE: CRS PSU should be applied to both CRS_HOME and RDBMS_HOME)
    I do see that RDBMS PSU 10.2.0.4.5(9654991) is available and the goal is to minmize the issues.
    Thanks.

    Hi,
    For 10.2 RDBMS/ASM home, you normally apply CRS PSU and DB PSU. It does not matter which is greater as you are on the same release like 10.2.0.4.
    So if you have CRS PSU 10.2.0.4.4 and DB PSU 10.2.0.4.5, this is fine as both patchset(s) are on 10.2.0.4.
    It is better to apply the same CRS PSU on both CRS and RDBMS/ASM homes.
    Hope this clears every thing.

  • CPU & PSU

    Hello,
    1)Correct me if I am wrong on following point:
    Any one who is concerned only with security fixes and not functionality fixes, CPU may be good approach. Right?
    2)There are many new features in 11.2.0.2. Are patch sets not just for bug fixes?
    Any help will be highly appreciated.

  • Require official Oracle Best Practices about PSU patches

    A customer complained about the following
    Your company statements are not clear...
    On your web page - http://www.oracle.com/security/critical-patch-update.html
    The following is stated!
    Critical Patch Update
    Fixes for security vulnerabilities are released in quarterly Critical Patch Updates (CPU), on dates announced a year in advance and published on the Oracle Technology Network. The patches address significant security vulnerabilities and include other fixes that are prerequisites for the security fixes included in the CPU.
    The major products patched are Oracle Database Server, Oracle Application Server, Oracle Enterprise Manager, Oracle Collaboration Suite, Oracle E-Business Suite, PeopleSoft Enterprise Tools, PeopleSoft CRM, JD Edwards EnterpriseOne, JD Edwards OneWorld XE, Oracle WebLogic Suite, Oracle Communications and Primavera Product Suite.
    Oracle recommends that CPUs be the primary means of applying security fixes to all affected products as they are released more frequently than patch sets and new product releases.
    BENEFITS
    * Maximum Security—Vulnerabilities are addressed through the CPU in order of severity. This process ensures that the most critical security holes are patched first, resulting in a better security posture for the organization.
    * Lower Administration Costs—Patch updates are cumulative for many Oracle products. This ensures that the application of the latest CPU resolves all previously addressed vulnerabilities.
    * Simplified Patch Management—A fixed CPU schedule takes the guesswork out of patch management. The schedule is also designed to avoid typical "blackout dates" during which customers cannot typically alter their production environments.
    PROGRAM FEATURES
    * Cumulative versus one-off patches—The Oracle Database Server, Oracle Application Server, Oracle Enterprise Manager, Oracle Collaboration Suite, Oracle Communications Suite and Oracle WebLogic Suite patches are cumulative; each Critical Patch Update contains the security fixes from all previous Critical Patch Updates. In practical terms, the latest Critical Patch Update is the only one that needs to be applied if you are solely using these products, as it contains all required fixes. Fixes for other products, including Oracle E-Business Suite, PeopleSoft Enterprise Tools, PeopleSoft CRM, JD Edwards EnterpriseOne, and JD Edwards OneWorld XE are released as one-off patches, so it is necessary to refer to previous Critical Patch Update advisories to find all patches that may need to be applied.
    * Prioritizing security fixes—Oracle fixes significant security vulnerabilities in severity order, regardless of who found the issue—whether the issue was found by a customer, a third party security researcher or by Oracle.
    * Sequence of security fixes—Security vulnerabilities are first fixed in the current code line. This is the code being developed for a future major release of the product. The fixes are scheduled for inclusion in a future Critical Patch Update. However, fixes may be backported for inclusion in future patch sets or product releases that are released before their inclusion in a future Critical Patch Update.
    * Communication policy for security fixes—Each Critical Patch Update includes an advisory. This advisory lists the products affected by the Critical Patch Update and contains a risk matrix for each affected product.
    * Security alerts—Security alerts provide a notification designed to address a single bug or a small number of bugs. Security Alerts have been replaced by scheduled CPUs since January 2005. Unique or dangerous threats can still generate Security Alert email notifications through MetaLink and the Oracle Technology Network.
    Nowhere in that statement is the Patch Set Update even mentioned. If Oracle intends to recommend to all customers that Patch Set Updates are the recommended means of Patching for Security and Functionality then it should be stated so here!
    Please clarify!
    Where can I find the current information so that I can use to Official Oracle statement as a reference for my Enterprise Practices and Standards document? The individual patch package references you are giving me do not state Oracle recommended Best Practice, they only speak to the specific patch package they describe. These do not help me in making an Enterprise statement of Practices and Standards.
    I need to close the process out to capture a window of availability for Practices and Standards approval.
    Do we have any Best Practice document about PSU patches available for customers?

Please be advised that this forum is simply a platform provided BY Oracle Corp as a peer operated user support group. No one here is responsible for anything on any Oracle web site.

  • Patching, CPU PSU

    hi,
    today I 've red through the Critical Patch Update from April. But my english is not good enough to understand everything. So maybe someone can help me.
    okay... in february I've installed a new linux-server with oracle 10.2.0.1, after that I upgraded to 10.2.0.4 and then applied the PSU from January
    what I had to do now? There is a CPU and a PSU for 10.2.0.4 and a PSU for 10.2.0.4.4
    CPU has only security fixes, right? PSU has bugfixes+securityfixes and is cummulativ (means I can install it on a blank 10.2.0.4). Can I install it too after the January PSU is installed?
    And for future... what do I have to do, if I omitted one PatchDay? Can I apply the next PSU, or is it necessary to first install the omitted CPU/PSU....
    sorry for this noob-questions, but I'm not able to get this information out of the documentations

    Hi,
    Whenever you apply next CPU patch its not necessary to apply the omitted patches...
    Its always there in read me file...
    PSU patches are CPU+bug fixes and sometimes they generate some new bugs..
    So its better to look in metalink about bug fixed and new issues with the PSU patch.
    Similar is case with PSU, its not necessary to apply omitted patch ,... you can directly apply latest PSU fro a db version.... better refer to readme..
    Also refer to forums..

  • Need to evaluate CPU or PSU patches

    Hi,
    Our business is on the way of migrating the databases. Before migrating the databases, we need to evaluate whether we need to apply CPU or PSU patches after migration.
    If we are positive on applying CPU patches, then we will migrate the oracle_homes as well, as we have been applying CPU patches after every release.
    In case if we are positive upon PSU patches, then we will be migrating only the databases.
    So with this scenario, we need to evaluate whether we need CPU or PSU. I did a basic analysis and found that PSU contains the CPU plus non-security updates. Therefore applying PSU is beneficial. Also we cannot mixmatch the patches i.e. if we are applying CPU, then we have to apply only CPU patches and if we are applying PSU then we have to apply only PSU patches. However we still need to know further details which could be captured from the answers to below questions.
    1. What are the risks and impacts of applying the patches.
    2. When Oracle releases both CPU and PSU, on what basis can we evaluate whether we need CPU/PSU when we are applying for the 1st time.
    3. If, after a period of time after applying patches, if we encounter any bugs and Oracle recommeds to apply a bug fix, what will be the implication that will be encountered if we have to apply on top of CPU or PSU patches.
    4. Will any situation arise where we need to apply a CPU patch, when we already have been applying PSU patch. If so do we have to rollback all the PSU patches or only the
    5. Do we need to install new oracle_home each time we are applying PSU patch
    6. Are there any ways we can reduce downtime. Are these hot patches. We have reduced our downtime while applying CPU patches by applying through OEM. How do we knoe whether they are hot or cold patches
    These are some of the questions. Maybe later on i may get more questions. But I would like to get a clear idea.
    Note: I had to write this elaborately, so that I can make myself clear on the scenario and also to avoid redundancy while posting messages.
    Thanks

  • Opinions about this PSU

    Hi everyone!
    I want to know opinions about this PSU, a Topower True 320W, it cost a half than an Antec True 430, and has the same values for 3.3, 5 and 12v. Here are the details
    http://www.topower.com.tw/home/atx12v_320p4.htm
    For what I've seen on THG website, seems to be a good one.
    Specs:
    DC Output +3.3V +5V +12V -12V -5V +5VSB
    Max        26A  32A  15A 1.0A 0.8A 2.5A
    Peak       28A  41A  19A 1.0A 0.8A 2.5A
    Combined     180W   180W  12W  4W 12.5W
                    300W            28W
    Peak Load 420W/60secs
    Efficiency 70% minimum at 115 VAC, 320W output
    Note: I'll use it at 230 VAC, I don't know if this will change any values of the above.
    Thanks in advance

    Stilup is right. Skimping on a power supply will only bring you more headaches than it's worth. Buy a Good brand name supply 400+ watts, and you will never run into tons of problems that others have, trying to run a hi power system with a $29.95 power supply. Every time you up the cpu ,you need more power. Bigger video card? more power. Add a drive? more power. If you buy a marginal supply in the beginning, you may get it to run your system, until you add something. I have seen hundreds of posts that when they finally divuge what the specs of thier supplys, it is painfully clear what the problem is. All my systems run at least a 400+watt supply with at least 220 combined watt. The exception to this rule, is True power supplys, that supply each single rail seperately ,so the combined thing doesn't apply. BD51
