Two instances/one running at a time with sae set of data files

hi,
I dont want to use OPS or Clustering...
I want two diffrent instances ... with only one running at a time....
When one will be down second will be manually started//
Only requirement is that the set of datafiles must be same.........
Is this possible...
waiting for some inputs..
thnx in advance

Oracle FailSafe is just a set of services that hook into Windows clustering to allow you to have an active/passive cluster (i.e. one instance mounted at a time). It just saves you the effort of manually configuring a bunch of things that Windows provides out of the box. I don't believe there are licensing implications to using FailSafe, but your Oracle sales rep would be the definitive answer there.
I'd strongly suggest that you use whatever clustering facilities are part of your OS. If you are trying to develop a general solution that will work on Windows and Solaris, I wish you luck. I'd bet it would be much easier to maintain a Windows-specific solution and a Solaris-specific solution using Windows- and Solaris-specific capabilities.

  • Copy structure of one report to another but with new set of data providers

    Hi,
    I have a requirement to copy the entire structure of a report into another new report but the new report will have a new set of data providers.
    How can we achieve this in BO V5.1.8?
    Thanks in Advance for your help.

    Hi,
    First thing first Take a copy of existing report,
    1.Open the report in edit mode.
    2.Click on the edit query.
    3.Click on the properties tab.
    4.Click on the universe name and change the universe with the new one.
    5.Now map the dimentions and measure of the new data provider to the old one.
    6.Run the report.
    Hope this will help you.
    Cheer,

  • How to Insert more than one record at a time- with fixed set of values in one field

    Can someone guide as to how to insert multiple records at a time using ASP VBScript in Dreamweaver CS4 or ADDT.
    If someone can guide then the exact problem is given below.
    I have a MS access database with one table. The table has three fields. The first field is an autonumber field for ID number.
    The second field contains string values- One out of 7 predefined values. One set of records consists of 7 records containing all the seven types of predefined values in fields no 1.
    The third field is a numeric field and can contain integers.
    I want that the user can enter data for the table using an ASP form in such a way that he enters one set of records at a time in one single screen. This way he will not have to remember that he has /has not entered all the seven set of values for the field no 1.
    I am not creating fields with the 7 types of field1value as their names as it will increase the number of fields drastically.
    Please help for dreamweaver ASP VBScript.

    I have successfully inserted seven records in one form submit operation by looping through the command object execute method.
    However, the data that is being inserted by the command object is repetition of the first record and the command object is not taking any data from the text boxes for the second record onwards. In this I had used the isert record behavious generated by DW CS4 and modified it to suit my requirement. However, the data inserted in the first row is getting repeated in all the seven rows.
    Please help.
    Also advise if there are any free dreamweaver server side validation extensions available.

    I had a generic record class that has a HashMap to hold the data fields (...)
    method called createRecord() for each record type which would populate the HashMap with the correct data fieldsI'm not sure I understand: are the contents of this field map the same between two records of the same type? Then yes, you don't need to clone the map per record instance.
    one thing that needs fixing is the fact that each time the createRecord() method is called I'm creating a new fieldMap to define the dataFields in the record class.Probably, but that will only get you a little bigger files; you won't gain an order of magnitude on the size of files. The problem for huge files is that as soon as their content is bigger than the available memory, you'll run into problems. A more radical approach if you need to address huge files is to process the records on the fly, and not load all records in memory. Of course not all algorithms or business logic can afford that...
    I know I could rewrite the code and create a class for each record type and declare the fieldMap static but I was wondering if anyone had any better suggestions The Record instance could receive and keep a reference to its RecordType instance, and ask the RecordType instance the DataType for a field's name. That way the RecordType encapsulates the map, and there's less risk that a clumsy other class modifies the static map.
    before I go rewriting a load of code.A load of code?!? Even with the idea of the static map, you only have to edit the enum type (well more accurately, each RecordType enumerated constant's createRecord() method).

  • Hi I am hoping to add my 2 TB time capsule to my existing wireless network using cisco dpq 3925 modem. I have two mbp one running Yosemite and the other os 10.7.5

    I have a time capsule 2TB model 1409. I would like to connect it to my existing wireless network (using a cisco DPQ 3925 modem). I have two mac book pro one running Yosemite and the other OS 10.7.5. The best I can do is to connect the TC to the Modem via ethernet. Have one of my MBP connect to the time capsule using a ethernet cable and have the TB set to bridge mode. In this configuration, both mbp and the iPad can detect the TC but when I try to connect it to the wireless network, using the same network name and password, the light flashes amber and I cannot detect the time capsule again.

    Correct..
    The best I can do is to connect the TC to the Modem via ethernet.
    The TC does not connect to non-apple routers by wireless.. well. It is possible but so poor a method that Apple seem to have eliminated it in the setup wizard.. I would take that as a good thing..
    If you cannot use ethernet you have two choices..
    Use another apple router that is plugged into the Cable modem.. eg a second hand Extreme Gen5 or the latest Express.. the Extreme is both cheaper and better.
    Or you can use a set of EOP (homeplug) adapters.. but they cannot be guaranteed to work so you should buy from a place that allows returns.

  • Embed pdf in website, show one page at a time, with forward and back controls?

    Hi,
    Not sure if this is possible (or if this is the right place to ask), but I need to take a multiple page pdf, embed it in a website so its on the left half of the screen, have it only show one page at a time, and have the forward and back page controls.
    Is this possible, and if so, could someone point me in the right direction?

    Typically you would save it to a JPeg and post those on the web site. Expecting a PDF to show up depends on the client computer configuration and browser. This is too risky, unless you don't mind getting nasty little notes that it does not work. If you do it with JPegs, then all the browsers I know of can handle it. Then simply put the PDF separately for those who prefer to download the PDF and look at it separately.

  • When I start mozilla firefox web browser, sometimes I see a message saying that "a Mozilla Firefox is already running, please close it or restart your program", while I don't have one running at that time. What is the problem?

    When I start mozilla firefox web browser, sometimes I see a message saying that "a Mozilla Firefox is already running, please close it or restart your system". As a matter of fact, there is no firefox browser running at that time. Since I cannot do anything about it, I have to restart my computer before I can use the web browser, which bothers me dearly. What is the problem?

    Plug-in and tasks started by Firefox may continue after attempting to close Firefox. The "X" in the upper right-hand corner closes the Window (same as Ctrl+Shift+W) but even if it is the last Firefox window, it does not necessarily close Firefox .

    The last part definitely suggests already that relying on uniqueness is incorrect. Hash codes are very often equal on distinct objects, viz. new String("java").hashCode == new String("java").hashCode(). Use a class level counter as suggested earlier.For that case we would of course expect the hashCodes to be equal, since the objects are equal. But even in the case of non-equal objects that don't override hashCode, you can still get the same value. Or, for that matter, non-equal objects that do override it. There are 2^32 possible hashCode values. There are 2^64 possible Long values. That means that there are 2^32 Longs that have a hashCode of 1, 2^32 Longs that have a hashCode of 2, etc.

    Thank you for reporting this issue. This is a known issue that we had fixed last week. In a few days, the updated version of the app will be available in the Windows store. At that time, your app should automatically get updated to the newest version, if
    you have not changed your default settings.
    If you still experience issues next week this time, please post back and perhaps share your workbook, so we can do a thorough investigation.
    Thank you.

  • Multiple wake-up times with pm set

    Hello, I have a question. I have 2 workflows that I have built through automator. I want them to start everyday at 4:00 and the other one to start at 22:00. The problem is that at those times, my mac would be asleep (or completely off) and automator would not run in those scenarios. I know the energy saver under system preferences has an option to wake up the computer but the problem is that it only gives me 1 option. So, I can either turn it on at 3:58 or at 21:58. I need to figure out how to get multiple wake up times for the mac (without purchasing any software).
    I have read some things on the internet about Pm set that would allow you to accomplish that. The problem is that I don't know how to use it. Is there a way to safely set this up with pm set? I have opened the terminal but I don't know how to use it. any help would be appreciated.
    Thanks.
    By the way, I am using the latest Imac model 2.7 GHz Intel Core i5 with OSX 10.8.3

    Does it have to run at exactly 0400 and 2200, or can it run after it wakes from sleep after that time?
    If that is the case, you may want to look at creating a launchctl plist to have it run whatever you want at those times. launchd will run them as soon as it wakes up after the scheduled time (or at that time if it is awake).
    There are quite a few examples online, but Lingon makes it pretty easy to create the plist and schedule the events. Even with Lingon, you would want to read up on launchd: http://developer.apple.com/library/mac/#documentation/MacOSX/Conceptual/BPSystem Startup/Chapters/CreatingLaunchdJobs.html

    Hi,
    Some users get this message -"Unable to copy data file;Error code 2, check disk space" when run report with orarrp, but most users do not get it.
    I check free space at both server and client side, they are very sufficient.
    I also checked directory exists for REPORTXX_TMP variable.
    My user call reports via URL (rwservlet) and it occur for all reports.
    How I can solve this problem?
    Thanks in advance.

  • How can I read a binary file stream with many data type, as with AcqKnowledge physio binary data file?

    I would like to read in and write physiological data files which were saved by BioPac�s AcqKnowledge 3.8.1 software, in conjunction with their MP150 acquisition system. To start with, I�d like to write a converter from different physiodata file format into the AcqKnowledge binary file format for version 3.5 � 3.7 (including 3.7.3). It will allow us to read different file format into an analysis package which can only read in file written by AcqKnowledge version 3.5 � 3.7 (including 3.7.3).
    I attempted to write a reader following the Application Note AS156 entitled �AcqKnowledge File Format for PC with Windows� (see http://biopac.com/AppNotes/ app156Fi
    leFormat/FileFormat.htm ). Note the link for the Mac File format is very instructive too - it is presented in a different style and might make sense to some people with C library like look (http://biopac.com/AppNotes/ app155macffmt/macff.htm).
    I guess the problem I had was that I could not manage to read all the different byte data stream with File.vi. This is easy in C but I did not get very far in LabView 7.0. Also, I was a little unsure which LabView data types correspond to int, char , short, long, double, byte, RGB and Rect. And, since it is for PC I am also assuming the data to be written as �little endian� integer, and thus I also used byte swap vi.
    Two samples *.acq binary files are attach to this post to the list. Demo.acq is for version 3.7-3.7.2, while SCR_EKGtest1b.acq was recorded and saved with AcqKnowledge 3.8.1, which version number is 41.
    I would be grateful if you someone could explain how to handle such binary file stream with LabView and send an example to i
    llustrate it.
    Many thanks in advance for your help.

    The reading of double is also straight forward : just use a dble float wired to the type cast node, after inverting the string (indian conversion).
    See the attached example.
    The measure of skin thickness is based on OCT (optical coherent tomography = interferometry) : an optical fiber system send and received light emitted to/back from the skin at a few centimeter distance. A profile of skin structure is then computed from the optical signal.

    Now, there is a check box that the user clicks that opens up a "List Builder" component where the user gets to select the "Product".
    Based on the "Product" selection, I want the column chart to display the respective data from the table above.
    Could anyone help me achieve this in the most efficient way?
    Note -
    Later, I also want to add a "Radio Button" for "Emp Type" and another "List Builder" for "Month". So, total 3 selectors. The other charts have their own sets of data.

    Hey jeewan,
    If i understood your question properly its all about the axis value of month & totals invariable product & employee. In this case remove the totals coming from the webi report. create a sum formula 30 rows below. But make sure how many records you will comsuming at the maximu level if you include all the values in the list builder and then decide where to right this sum formula. Now pick the month from the top and total from cells where you have written the sum formula.
    Got it, does it helps!!!
