Advantages/Disadvantages of single/Multi 10g DB&AS Server for 2 application

Hi Friends,
I am using Application1 using Oracle 10g Application Server and Oracle 10g database.
Now i planned to use Application2 using Oracle 10g AS and Oracle 10g DB
I need to know what will be the Advantages and Disadvantages if i have the schema for Application2 in the existing Oracle 10g DB / having it in another Oracle 10g DB Server
sameway what will be the advantages and disadvantages if i have the Application2 regsiterd in existing Oracle 10g AS(Multiple OC4J Instance) / having it in another Oracle 10g AS Server.
Regards,

Hi,
Personally i would'nt suggest using the Application server, due to
1. If you need down time for application patching, you custom application will also be down.
2. If you can not start 10g Application server (The one came with R12) for some issues, it will also affect your custom application.
3. If you are upgrading/patching 10g application server (the one came with R12), you would not know what will the affect of this on custom application.
E-Business Suite Software Development Kit for Java (includes AppsDataSource, Java Authentication and Authorization Service) Readme - Patch 9863609 [ID 974949.1]

  • Reports 9i/10g J2EE Thin Client for Websphere Application Server 5.x /6.x

    We are having Reports developed in 6i which needs to be migrated to Reports 9i/10G and we want to deploy these reports in web using Websphere Application Server 5.x /6.x without Oracle iAS.
    Do we have Reports 9i/10g J2EE Thin Client for Websphere Application Server 5.x /6.x and if so please let me know.
    Also if anybody has the configuration details please let me know?
    Thanks in Advance.

    No there is not. I don't think you can use reports services with Websphere - besides as far as I know it is not supported by Oracle (not anywhere in their support matrix).

  • Is there a single click VNC/screen sharing server for OS X?

    First, if this is posted in the wrong section then please forgive the error and relocate the post to the appropriate section.
    I'm looking for a small distributable single click screen sharing system for tech support purposes. I generally support Windows users but sometimes need to quickly gain access to remote OSX systems from fairly clueless users. Every minute I spend explaining something that the user does not want to know or does not need to know is a waste of our mutual time. Thus I'm looking for something similar to UVNC single click for OSX. That is a distributable VNC server reduced to about 250KB or less that can be configured to automatically connect to a listening viewer on launch.
    Is there a program or perhaps an executable script file that will initiate such a connection?

    Start with Applications -> Automator. You can have it "Record" the setting up of the VPN server of your choice.
    Then there is AppleScript, but for me that generally requires a book and Google searches to find examples close to what I want to do.
    It may be possible to do some stuff via Unix shell scripts (sh, bash, awk, perl, python, ruby, etc...) and then invoke this via an Automator action, an AppleScript command, or just wrap the shell script using Platypus (search Platypus at VersionTracker.com).
    If you need to configure the customer's Mac OS X firewall, that might also be an Automator action, or since the firewall is really the Unix ipfw (man ipfw), that could be a use for shell scripting.
    If you need to fetch stuff from the web as part of your installation, you could use something like /usr/bin/curl in a shell script.
    Setting up automation can be difficult and I'm not making light of the task. What might look like a good approach may find that the last 5 inches just can be done and you have to back track and use something else. And then there are the variables created by the fact that every customer will be different and you will find that some expected situation doesn't exist because the customer has customized something.
    NOTE: The Vine Server (aka OSXvnc) can be setup to make a reverse connection. It may even be possible to use an Automator script to setup that connection for you, specifying the address.of.your.VNC.client and port number you are using.
    Or create an AppleScript (which might be more robust than Automator).
    Or establish an example reverse setup, then using "ps -axlww" see what the actual server command line looks like, then create a shell script wrapped by Platypus to do this for the customer.
    OK, your turn to go chasing down dead-ends and practice backing out. After all you are the one that is going to get paid, I'm just doing this for fun
    However, if you need to configure a customer's router that could be a problem as every darn one of them is different.

  • Advantages/Disadvantages of having 2 Apple ID's with iCloud - Single User

    A separate Apple ID for iCloud and a separate Apple ID for Store Purchases - 1 Mac and 1 iPhone - both to 1 Single User.
    I'm both curious and interested at the same time..
    And would it even be useful? Or should I just stick to using the same Apple ID because in creating another Apple ID, I'd be giving myself more of a hassle when it comes to backing up/restoring?
    I'm still running my mind around this one... (cos it only seems to benefit users who are all iDevice holders living under the same roof etc.. with 1 root Apple ID and multiple iCloud Apple ID's per individual)
    I am relatively new to Apple and am exploring this idea keenly.
    What are the Advantages/Disadvantages for this particular scenario??
    Thanks a lot to those who kindly contribute your thoughts! 

    Basically 1 Device sharing 2 separate Apple ID's.
    1 For App Purchases.
    1 For iCloud.

  • Advantage/disadvantage in OS and Oracle clustering

    Dear DBAs
    i need to know what are the advantages and disadvantages in using Oracle clustering instead of OS clustering.
    I will be thankfull if you can provide a table (advantage/disadvantage) for each case.
    The OS is windows 2003 and the database is 10g
    Thx in advance
    Regards

    One advantage could be you don't need to buy OS clusterware as it comes bundled with Oracle 10g.
    So Cost benifit is One of the advantage.

  • Advantages/Disadvantages of installing Oracle RAC on Windows 2003 VS Linux

    Hello Guys,
    I am not very good with linux, have to create a Oracle RAC environment using dataabse 10g.

    Please help me with this. Please also specify what is the best available windows and linux version to configure RAC.
    Regards,

    Go with th eOS you have the skills in, if you have onsite expertise in windows then it makes no sense to use Linux because some guy on the internet says its better. Windows can be a highly available server OS when is managed by professional well quallified adminstrators.
    Personally I would use linux because I am more familiar with the OS than windows. I also find oracle makes more sense on a *NIX type platform but there are shops that run oracle on windows with the required high availability.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       

  • XI & Biztalk - advantage & disadvantage

    What are the  advantage & disadvantage of XI & Biztalk ?
    Which one is best solution as a middleware ?
    Please provide in relavance to adapters IDOC etc..

    Sap XI
           XI is well suited for connecting SAP systems with each other and with non-SAP. SAP XI provides an integrated workflow engine that allows defining adapters to non-XML protocols and mappings to convert data content from source to target format.
    XI comes handy particularly incase of SAP - Non SAP interfaces where you can import standard integration content. Also XI has got sophisticated open standard adapter framework which is very easy to implement and custom logic can be implemented using Adapter module programming.
    Advantages
    Monitoring is better than any other middleware product. It offers exhaustive monitoring features like message, performance, component monitoring etc, all of which can be used to track and rectify the errors. It follows a hub and spoke model.
    When you need to integrate with an SAP system XI has an advantage in supporting various SAP components and so on.
    Process functionalities inside XI to modify content in the communication channel on own defined rules for business purposes.
    Mappings and adapters are good as comparable with any other middleware product.
    Synchronous & Asynchronous communication is possible.
      Dis-Advantages
    Web methods are particularly good if u have B2B kind of communication with their Trading Partners product.
    XI is lacking full-fledged Message Queue compared to other established Middleware products.
    It lacks in ability to process huge messages but SAP is working on that.
    It does not have a messaging layer exposed by APIs like IBM MQ-Series.
    It is not comparable to Tibco in terms of speed.
    SAP relies on other vendors except for a few adapters.
    3. BizTalk
                BizTalk is a business process management (BPM) server that enables companies to automate and optimize business processes. This includes powerful, familiar tools to design, develop, deploy, and manage those processes.
                While planning for the integration scenario BizTalk takes care about tasks like Gathering information, Defining naming conventions, planning team development, setting up and working with source control.
    Advantages
    BizTalk 2004 is completely built on .Net.
    Recoverable Interchange. In BizTalk, an Interchange can contain two or more messages, such as a batch. With the introduction of Recoverable Interchange in BizTalk Server 2006, only messages that fail validation are suspended, and the messages can be resumed after the error is corrected.
    Failed message routing. New functionality is available to allow orchestration and send ports to subscribe to failed messages. When used appropriately, failed message routing can be used for notifying users of failed messages or building rich error handling and message repair capabilities.
    Lowest total cost of ownership (TCO). BizTalk Server reduces the cost and complexity of automating and managing business processes with a single, unified solution for Enterprise Application Integration (EAI), Business-to-Business integration (B2Bi), and Business Process Management (BPM).
    Enhanced productivity through integrated management and development tools.
    Supports Computer Telephony Interface (CTI) through TAPI.
    Dis-Advantages
    Recovery is manual.
    Backups are not automated.
    Fault Tolerance capabilities are supported through other Microsoft products.
    Repository only works with MS SQL.
    Requires additional software to use certain features in BizTalk 2002, Microsoft Operations Manager & Application Center.
    To use a server with 8-32 processors it requires Microsoft Windows 2000 Datacenter, which must be purchased through an OEM.
    Only runs on Microsoft/Intel platform and only supports XML Data Reduced (XDR) not XML Schema Definition (XSD).

  • What are advantages/disadvantages of getting iphone through Apple store vs. Verizon?

    What advantage/ disadvantage is there to getting an iphone 6 through the Apple store vs. Verizon? Currently my provider, single plan and eligible for an upgrade. Think the $60.00/month of unlimited talk,text and 2GB data is what I'm interested in with Verizon. Thank You.

    I can't think of any significant difference if both stores are in an equally convenient location for you other than if you plan to purchase AppleCare +, it might be slightly more convenient to buy the phone at the Apple Store and buy that at the same time. http://store.apple.com/us/product/S4575LL/A/applecare-for-iphone

  • Advantages / Disadvantages of 10gAS over Forms Server 6i

    Hi gurus,
    Is there any document/ links available related to advantages/disadvantages of Oracle 10gAs over Forms Server 6i. Either it can be functional wise/ performance wise/ feature wise/ configuration wise/ any thing else.
    Thanks in Advance
    Justin

    I don't believe so (we I certainly didn't write one!). If you go to otn.oracle.com/products/forms there are some new papers explaining the new features in each version subsequent to 6i. So in effect you can compare 6i and 10g by looking at the new features. However, support might be the biggest reason. 6i Forms is no longer supported.

  • Advantages & Disadvantages of RAID and How affect Qosmio G30 speed

    Hi.
    i heard that setting RAID can increase or not speed.. can anyone more expert explain me how this works?
    1.) First of all what is RAID (explain in words that an ignorant in computing like me can uderstand)
    2.) What's the difference between raid 0 or raid 1 and how it affect the computer?
    3.) What are the advantages/disadvantages choosing between this two settings?

    Hi
    Im not a RAID guru ;) but I have used the Qosmio G20 with and without enabled RAID technology and I did not notice any speed disadvantages.
    I see you are a newbie and therefore I will try to explain the RAID functionality very easily ;)
    So what is RAID? RAID (Redundant Array of Independent Disks) helps to save data.
    The RAID mirrors the content of the first HDD to the second HDD. That means that all files (depending on the RAID settings) which are stored on the HDD1 are also stored on HDD2. If the HDD1 will damage, you will be able to recover the whole content from the HDD2.
    The two HDDs can be used with RAID-1 mirroring or RAID-0 stripping
    When using RAID-1 the data is stored twice (once on each of the HDDs) so if there are problems with one of the HDDs, the other HDD can be used to recover the data.
    But you can use the both HDDs only as a single HDD. (2 HDDs = 1 HDD)
    When using RAID-0 (stripping) the size seen by the OS is twice!
    Using the RAID-0 configuration, all data on both disks will be lost, even if only one of the two disks fails!!!
    I think the RAID is very useful because it safes the HDD content!
    Of course, if you use the mirroring option you can use only the one available HDD!!!
    But you are on the safe site ;)

    SAXParser
    Both DOM and SAX approaches have advantages and disadvantages, and your choice of technique must depend on the type of data being parsed, the requirements of your application, and the constraints under which you are operating.
    The SAX approach is linear: It processes XML structures as it finds them, generating events and leaving the event handlers to decide what to do with each structure. The advantage of this approach is that it is resource-friendly; because SAX does not build a tree representation of the document in memory, it can parse XML data in chunks, processing large amounts of data with very little impact on memory. This also translates into better performance; if your document structure is simple, and the event handlers don't have anything too complicated to do, SAX-based applications will generally offer a speed advantage over DOM-based ones.
    The downside, though, is an inability to move around the document in a non- linear manner. SAX does not maintain any internal record of the relationships between the different nodes of an XML document (as the DOM does), making it difficult to create customized node collections or to traverse the document in a non-sequential manner. The only way around this with SAX is to create your own custom object model, and map the document elements into your own custom structures—a process that adds to complexity and can possibly degrade performance.
    Where SAX flounders, though, the DOM shines. The DOM creates a tree representation of the document in memory, making it possible to easily travel from one node to another, or even access the same node repeatedly (again, not something you can do easily in SAX). This tree representation is based on a standard, easy-to-understand model, making it easier to write code to interact with it.
    This flexibility does, however, come with an important caveat. Because the DOM builds a tree in memory, DOM processing cannot begin until the document has been fully parsed (SAX, on the other hand, can begin parsing a document even if it's not all available immediately). This reduces a developer's ability to "manage" the parsing process by feeding data to the parser in chunks, and also implies greater memory consumption and consequent performance degradation.
    Consequently, the choice of technique depends significantly on the type of constraints the application will be performing under, and the type of processing it will be expected to carry out. For systems with limited memory, SAX is a far more efficient approach. On the other hand, complex data-processing requirements can benefit from the standard object model and API of the DOM.
    After using DOM to parse XML documents for any length of time, you will probably begin to notice that performance tends to suffer when you’re dealing with large documents. This problem is endemic to DOM's tree-based structure: larger trees demand more memory, and DOM must load an entire document into memory before it can allow you to parse it. For situations where performance is problematic with DOM, you have an alternative in the Simple API for XML (SAX). In this fifth installment in our Remedial XML series, I'll introduce you to the SAX API, and provide some links to SAX implementations in several different languages.

  • What are the advantages/disadvantages of using PS/CS5 in 64bit over 32bit please?

    What are the advantages/disadvantages of using PS/CS5 in 64bit over 32bit please?

    From a practical perspective, besides the 64 bit version being a bit faster at just about everything, limitations on document size are lifted in the 64 bit version.  Essentially, how much can do is limited only by how much RAM you have installed in your system.  You can do things like have larger documents, deeper history, etc. and have it all work quickly.
    On the other hand, many 3rd party plug-ins, especially older ones, only provide 32 bit versions, which will only run in 32 bit Photoshop.
    Both 32 and 64 bit versions are installed by default.  It's important to note that most of the preferences are separate between the two, so you can have two slightly different setups that might help with specialty operations you might need.  This gets pretty subtle, but for example I keep the 32 bit version configured with only 1 cache level, so all previews of high bit depth images are always composited in high bit depth.  This aids me with some aspects of astroimage processing.  It's slower, but more accurate.  By contrast I have more cache levels configured for my 64 bit version, so that's faster for general photography work.
