Help with determining required CPU

Hello All,
I just inherited an 11g DB that has not been bounced sinced July 2009. It is the only production host, not in any RAC or standby config. Being a bit of a niewbie, how do I determine what the last patch was applied, and next question, assuming its behind, becuase I heard there hasn't been any updates applied to this box since then, can I just download the latest CPU and Opatch that?
DB is an Oracle 11g (11.1.0.7) 64 bi ton Redhat 5.3 (Even the Linux OS is telling me there are 120+ updates that have to be applied. This looks like a huge OS and Oracle update task..
Appreciate any feedback..
RN

Hello,
By applying CPU JAN 2010, will that cover all the patches in the past and some security patch that was released 4 or so months ago?Yes generally the CPU are cumulative.
You have also the PSU (Patch set Update) which include the CPU and are also cumulative.
The PSU fix Bugs and not only security vulnerabilities.
They are released on the same day than CPU.
Best regards,
Jean-Valentin

  • Help with determining PANTONE swatches accurately

    I've recently designed a logo for an event. It's a 3-color design done entirely using process colors. The client would like the PANTONE equivalent of each color, however, and I'm having a lot of trouble figuring this all out (I'm a bit of a prepress newbie).
    First of all, I have a lot of questions about the LAB view vs. CMYK view for spot colors in Illustrator:
    1) The difference between the two is HUGE. In CMYK view, there is less subtlty, but the colors are vibrant and versatile. In LAB view, I can access certain colors I can't otherwise get, but most of the palette is desaturated and muddy. Is it supposed to be this way?
    2) Supposedly, the LAB view for spot colors is relatively new in Illustrator. Considering how far off-base the CMYK versions of each spot swatch is, how was anyone getting work done before this feature was added? I don't understand how I could have even hoped to do spot color work using the CMYK swatches in older versions. They're entirely different colors in many cases. I must be missing something.
    3) Is it accurate to say that, monitor calibration notwithstanding, and all other things being equal, the LAB view of a given spot color is more "accurate" than the CMYK version? If this is the case, the PANTONE uncoated library of solids is incredibly dull and muddy, because that's how it looks in LAB mode. I've been browsing a physical PANTONE book as well, and the colors don't appear to be nearly as bad in real life. My monitor may not be perfect, but I can't believe it's so poorly calibrated that the colors could look THIS different.
    4) When viewing my work in LAB view, one of my colors translates perfectly from CMYK, while another doesn't even come close when attempting to match it with a spot color. In CMYK view, it's reversed-- the first color looks terrible, while the second actually comes pretty close. Which version can I trust? They're total opposites, making the final selection of a single swatch impossible. I'm not sure what to give my client-- if they're using an older version of Illustrator (which is likely), they'll have to see this in CMYK mode, and it will look terrible. Even a PDF I exported doesn't look right in Acrobat. How should I be approaching this?
    As you can see, the seemingly simple task of selecting PANTONE swatches for 3 CMYK colors has turned into a bit of a mess. Any help with these confusions of mine would be hugely appreciated.
    Thanks!

    Aleister,
    my simple advice concerning Spots, is this:
    Buy a swatch book for Pantone Spot Coated and a swatch
    book for CMYK for your Process Coated, as recommended
    by your printing company (here ISO Coated, maybe SWOP
    elsewhere).
    Then compare visually the chosen Spot and a matching
    process color.
    If there is no good match, then you can print only
    by Spot.
    If you've found matching pairs, then you can print
    letterheads by Spots and 4-color brochures by CMYK.
    Personally, I'm using as equivalents for Spots only
    two-color process colors, if e.g. a logo has to be
    designed. This leads to minimal registration errors.
    Another ugly truth is, that even an accurately calibrated
    proof printing system by inkjet cannot reproduce plenty
    Spots sufficiently accurate.
    Meanwhile you may try to investigate all this by a true
    Lab doc for common Spots:

  • HELP With security requirement

    Dear All,
    I�ve been working with J2EE for a while and now i am facing a requirement I assume J2EE can face but I would like some professional orientation.
    I�m developing a financial systema, Web & server, using GalssFish. The requirement I have is that "any system service" as I call the operations accessible from the client (web app) should be permission secured, that means, that for each User or Role, I sould be able to configure wich system services it can access ( at least) or more in depth wich level of security it has.
    Roles are not fixed, the sysadmin should be able to configure any Role, and assign to it any User, what is fixed are the system services. The permissions to each role for system service access should be configurable.
    I hope the explanation is understandable,
    Can anyone help me in order to assume this is possible with glassfish, and where could I read something nearly close to what I need (i�ve read JEE tutorial, and a buch of papers of security in EJB and Web tier but none provides information for my requieremtent).
    Regards,
    Germ�n Viera.

    Marco,
    One place you could put additional auth-check for you custom table is SE11 -> Utilities -> Table maintenance generator -> Environment -> Modification -> Events.
    I believe Event 25 is for inserting Auth-Check on table fields.
    Hope this help.

    Modify /etc/redhat-release and change the line to "Redhat Enterprise Linux 3 (Taroon)"
    or
    execute runInstaller with "-ignoreSysPrereqs" parameter.

  • Help with images required

    Hi, I am a new Macbook owner. I transfered some photos from my canon camera last week. Today some of these are corrupt. I tried sending the folder to a friend yesterday using podmail. Quite a lot of my images are now corrupt, but not all. All I have done is resizing in Preview a few days ago. How do I fix my images? They are very important to me as they are of me and my girlfriend. Any help is greatly appreciated.

    First, did you erase the camera? If not, import the pictures again.
    Second, are the pictures in iphoto? If they are, then look in your iphoto library in your user/pictures folder and look at them to see if there are originals that weren't messed with or which are otherwise ok. If they aren't in iphoto, try importing them into iphoto and then looking at them again.
    If you erased the camera and the images are all indeed screwed up, then you need to look at what you mean by "corrupt." Is it that the pictures themselves are mucked or that you can't open them. If the pictures are bad, then your only option is to play with them to try to improve them and there is no magic bullet. If you can't open them, then select one, get info on it (command + I) and see what the thing is set to open with. Make sure a photo program like Preview or iPhoto is selected and not some text program or the like.

  • Help with this requirement

    Hi Experts,
    i have a requirement: i have a customer table and fact table with contains operations performed by that customers. In cust table, there is a column name CUST_KIND with contains the kind of customer. This value can change, so i need to construct a report that shows that changes of customer kind. To achieve this, in the report, i create a new field with EVALUATE and LAG sentences to catch the value of CUST_KIND of previous row, and i order the report by cust_id and time. I have the problem that analytic function LAG can't be used in WHERE clause... so, how can i achieve my requirement??? Please, answer it ASAP
    Thanks in advance.

    Hi friend,
    thanks for response. The fact table contains operations performed by customers. One column of that fact table is 'kind of customer', and this is the field that can change. So, One customer can change of kind from one week to other, so, one week can perform operations being one kind of customer and next week can perform operations being other kind of cust. Because of that, i need to build a report that shows that changes of kind of customer, comparing cust kind of one week with cust kind of previous week.

  • Need help with determining which Credit Card would be the best

    Here is my situation. Currently only have one credit card, BoA Alaskan Airlines (since 2008) that is pretty much maxed, $6k balance on a $7k limit. I would like to open another card with a 0% balance transfer to help me pay this down as well as lower my utilization.  I have solid credit history, no delinquents and have perfect payment history. No current loans or installment payments and last credit check was earlier this year, a 704 with Experien. I have been comparing the Chase Freedom, Slate and Discover IT and wanted to see what your experiences were and what chances you think I have of qualifying for each card. Which card would be best for my situation? Thanks in advance.

Which card would be best for my situation?Let me give you an example of how constricting high utilization can be.  I was in a similar boat but I had more cards and, aside from utilization over 60% a solid credit profile in good standing.  However, Chase would only approve me for a $2K Slate with the highest APR offered at the time.  It was completely useless.  I was able to get my utilization down to under 10% (I think close to 2%) 6 months later.  At that point I had 2 instant approvals within a day of each other.  Each of those Chase cards were approved for $25K.  Approvals at that point were qualifying for the lowest APR on cards with ranges. I'm not saying that you'll get $25K when you lower your utilization.  Again, just demonstrating how constricting high utilization can be, If you're going to app then you want your credit to be in the best possible shape.  At 85% on your only card you're a long way from that.  I know that's not what you want to hear but it would be unreaslistic IMO to encourage to to expect a card useful for BT and for lowering your utilization.

  • Help with validating required fields

    I have approximately 50 columns in a result set. I need to find out if the required fields (20 out of those 50 columns are required fields) have values (not empty field).
    Since I'm dealing with a large result set (approximately 3000 to 5000 records), what is the most efficient thing to do to validate each field?
    For example:
    Column A, B,C,D.E.F, etc are required fields, I need to validate that each of these column has value otherwise I need to <CFABORT> the process and notify the user.

    The data is not yet in our database,they are created in memory when the app. is run.
    I have sort of  Xml To Query function that generates a result set. I'm doing some validation on req. fields before they are inserted into our DB.
    I try to run your code but I got an error:The value '' cannot be converted to a number
    Here is my code imitating yours (For testing I'm using fewer columns):
    <CFSET MandatoryFields = "Org,OrgId,LastName,FirstName,Gender,Address,City,State,Zip,Phone">

  • Help with a Requirement for a manager's direct reports

    Hi All,
    I have a requiremnt for a manager to be able to see his direct reports in US alone.
    ex: A manager is in US, he has reportees who are in US, and also reportees who are in other countires on other foreign assignments..but this requirement shld give him only the reportees present in US and exclude reportees who are working in other locations.
    i have a solution kinda..but not sure its the right way..i am thinking first pull out all his direct reports and then filter out based on all those employees for whom.. IT0710 is maintained.But i am not sure, if IT0710 is alone the determining factor for employees on foreign assignment..
    pls advice.

    Hi Mike,
    According to your description, I understand you have delegate permission and you want to create a rule to move message to your inbox.
    If I misunderstand your concern, please do not hesitate to let me know.
    Depending on my research and testing, it's unpossible. Rules are processed during send/receive or when selected manually so hooking it to the "Mark as Read" action would require a completely separate processing mechanism.

  • Help with Required fields-PLEASE

    I have been attempting to get help with a required field and one of the forum helpers said he got it to work for me but I cannot and I have not been able to get any more responses from him to help me further.
    I am attempting to have a radio box when the YES is selected to require another field to be completed.  The script I was provided with is:
    getField("Location").required = (getField("Group1").value == "Yes");
    Location being the field that I require to be filled in if Group 1 is Yes.  The previous forum helper indicated that I had to have this script in both fields in Group 1 and when I do that, nothing different happens. 
    What am I doing wrong? 
    Please, I need to fix this right away and I will be using this java script on many other forms that I have so I need to get this done soon.
    Thank you in advance.

    Wht you want can get somewhat complicated. One way to prevent subsequent fields from being used is to set them to read-only and/or hidden. You could then use the Validate event of the text field to validate the entry and enable the subsequent fields if it is filled-in adequately. In general, you should also reset the fields whenever you hide them, so they don't contain potentially invalid data from previously being filled-in. So you could initially have the fields set to be hidden, and only unhide them if No is selected, or if Yes is selected and the required text field is filled-in.
    I realize this may not be as helpful as you had hoped for, but I can't suggest specific code without knowing more about the form.

  • Help with Conditional Display and Validation

    Version 4.1.1.00.23
    Hello,
    I'm having a difficult time with a conditional display and validation I'm hoping someone can help with.
    Requirements:
    When the Start Date (Datepicker) and/or End Date (Datepicker) change then display the Change Reason (Select List) and Change Description (Textbox)
    If the page is saved without entering a Change Reason display a validation error message that the Change Reason cannot be empty (NULL)
    What I've tried
    Create a Dynamic Action on the Start Date
    Event: Change
    Selection Type:Item(s)
    Items(s): P51_START_DATE
    Condition: none
    True Action Section:
    Action: Show
    Fire on Page Load: Checked
    Show all page items on the same line: No
    Affected Items Section:
    Selection Type:Item(s)
    Item(s): P51_CHANGE_REASON,P51_CHANGE_DESC
    I've also created a Dynamic Action with similar settings for the P51_END_DATE.
    I created a Validation for the P51_CHANGE_REASON as Function Returning Error Text:
    DECLARE
        v_start_date    work_items.start_date%TYPE;
        v_end_date      work_items.end_date%TYPE;
    BEGIN
        SELECT start_date
              ,end_date
        INTO   v_start_date
              ,v_end_date
        FROM   work_items
        WHERE  work_items_id = :P51_WORK_ITEMS_ID;
        IF ( (v_start_date != TO_DATE(:P51_START_DATE,'DD-MON-YYYY') OR v_end_date != TO_DATE(:P51_END_DATE,'DD-MON-YYYY') ) AND
              :P51_CHANGE_REASON IS NULL ) THEN
            RETURN 'Change Reason must have a value';
        END IF;
    END;
    The Issue
    I tried to create another Dynamic Action to hide the P51_CHANGE_REASON and P51_CHANGE_DESC fields on page load, but when either of the date fields are changed and the validation is fired the P51_CHANGE_REASON and P51_CHANGE_DESC are hidden again.
    There are two buttons to submit the page: 'SAVE' will submit the page and stay on the page and 'SAVE_CHANGES' will submit the page and branch to the previous page (which is a report with EDIT buttons to edit the record).
    I can't get the page load Dynamic Action to NOT fire when the validation is fired.
    I hope this is clear and if not what information can I provide?
    Thanks,
    Joe

    Phil,
    Thank you for looking at this.
    Yes if the Change Reason is NULL when the edit page is displayed then the Change Reason and Change Description fields are hidden. If the Start Date (Datepicker) and/or End Date (Datepicker) change then display the Change Reason (Select List) and Change Description (Textbox). If the page is saved without entering a Change Reason display a validation error message that the Change Reason cannot be empty (NULL).
    The problem I'm having is that if no Change Reason is entered and the page is saved thereby firing the validation the Change Reason and Change Description fields are hidden again (because of the On-Load Dynamic Action to hide them). So now the user can't put in a Change Reason...unless they change one of the date fields again which isn't going to be accepted.
    Is there a way to determine if a validation error was fired and be able to use that on the On-Load Dynamic Action to hide the two fields? Something like...If the validation fired then don't run?
    Please let me know if I'm still confusing you.
    Thanks,
    Joe

  • Help with validation on a manually created tabbed form

    version 4.1.1.00.23
    Hello,
    I have a manually created tabbed form that I'm having trouble creating validation on.
    The page is a Resource Staffing page where PM's can forecast the Resources that will be needed for various projects. The forecast can be for 12 - 18 months.
    The requirement is to display a message to the user if they are trying to save a row without forecasting any time. It's possible they may not know how may Resources or the length of time needed when the row is created.  If they respond that they want to save the row without time the MRU will create the record. If they answer that they do not want to save the row they are returned to the page without loss of information.
    The month fields on the page are defaulting to 0 (zero).
    I've updated the Save button to Redirect to URL and in the URL Redirect I have: javascript:confirmNoTimeSaved()
    The javascript:
    [code]

  • Help with GBIC selection LH vs ZX

    Dear Support,
    I now have the estimated Attenuation values from our fibre provider, and wondering if anyone could help with determining if I can utilise the cheaper (LH modules) across the 20 & 15 KM streches.
    Thanks in advance (many thanks to Josh for helping out with my previous post - below)
    HQ to DC1 = 1310nm: 2.5dB, 1550nm: 2.2dB.
    DC1 to DC2 = 1310nm: 14.5dB , 1550nm: 13.1dB
    DC2 to HQ = 1310nm: 10.1dB, 1550nm: 9dB
    =========================================
    Dear Support,
    Sorry but new to optical networking, but need some assistance on an upgrade that we are performing.
    We currently have two data centres that hold our servers and are planning to upgrade from LES circuits to Gigabit links, and triangulate our topology. (effectively a ring topology)
    I have already spoken to our proposed fibre provider and they have provide me with rough distances, but due to one of the data centres being more than 10 km away we need to use ZX based GBICs. Summary of distances below;
    HQ -> dc1 (1 – 2 km)
    HQ -> dc2 (15 km)
    Dc1 -> dc2 (20 km)
    From our HQ to dc1 we will use LH (via a GLC-LH-SM= in a 2970G) and a to dc2 we will use ZX (via a GLC-ZX-SM= in another 2970G)
    From DC1 to HQ we will use LH (via a WS-G5486 in a 7204VXR) and a to dc2 we will use ZX (via a WS-G5487 in another 7204VXR)
    From DC2 to HQ we will use ZX (via a WS-G5487 in a 7204VXR) and a to dc1 we will use ZX (via a WS-G5487 in another 7204VXR)
    Hope this doesn’t confuse things more.
    Now to the question.
    From the Cisco web site it mentions the following;
    When shorter distances of single-mode fiber are used, it might be necessary to insert an in-line optical attenuator in the link to avoid overloading the receiver:
    • A 5-dB or 10-dB inline optical attenuator should be inserted between the fiber-optic cable plant and the receiving port on the Cisco 1000BASE-ZX GBIC at each end of the link whenever the fiber-optic cable span is less than 15.5 miles (25 km).
    We haven’t yet had the fibre survey performed, but once they have advised me of the attenuation on the link, how should I calculate what level of “in-line optical attenuator” I should need or should all reputable fibre providers advise me of this detail.
    Thanks in advance.

    Summary of Optical Levels:
    GLC-ZX-SM:
    Transmit: 0 to +5
    Receive: -23 to 0
    GLC-LH-SM:
    Transmit: -9.5 to -3
    Receive: -20 to -3
    G5486:
    Transmit: -9.5 to -3
    Receive: -20 to -3
    G5487:
    Transmit: 0 to 5.2
    Receive: -24 to -3
    Given the above:
    HQ -> DC2: maximum receive level will be 5-10.1 = -5.1 dB, which is OK for the G5487
    HQ <- DC2: maximum receive level will be 5.2-10.1 = -4.9 dB, which is OK for the GLC-ZX-SM
    HQ -> DC1: maximum receive level will be -3-2.5 = -5.5 dB, which is OK for the G5486
    HQ <- DC1: maximum receive level will be -3-2.5 = -5.5 dB, which is OK for the GLC-LH-SM
    DC1 -> DC2:maximum receive level will be 5.2-14.5 = -9.3 dB, which is OK for the G5487
    DC1 <- DC2:maximum receive level will be 5.2-14.5 = -9.3 dB, which is OK for the G5487
    Therefore, you do not need attenuators anywhere.
    Now, to your next queston. If you used the LH modules, you the minimum possible receive levels now become:
    HQ -> DC2: minimum possible receive level will be -9.5-10.1 = -19.6 dB, which is only just OK for the G5486
    HQ <- DC2: minimum possible receive level will be -9.5-10.1 = -19.6 dB, which is only just OK for the G5486
    DC1 -> DC2: minimum possible receive level will be -9.5-14.2 = -24 dB, which is too low for the G5486
    DC1 <- DC2: minimum possible receive level will be -9.5-14.2 = -24 dB, which is too low for the G5486
    Therefore, my recommendation is to stick with the ZX modules for these links.
    Hope that helps - pls rate the post if it does.
