What are the network restrictions for a Tuxedo MP configuration between the Master and Backup?  Can they be on separate networks?

We are migrating from one data center to another and want to keep 100% uptime during the process.  The two data centers are on separate networks but in the same city.  I want to migrate the Master and the Backup to the new data center with zero downtime. 

Hi Harvey,
Tuxedo machines just need TCP/IP connectivity.  So machines can be in different subnets, different Ethernets, etc.  I know of one customer that has a 13 machine MP configuration that is distributed across the entire country.  So as long as there is a route between the machines, you should be fine.  Here's an old but probably useful white paper on bridges, multiple networks, etc., from Aurora Information Systems:  "Exploring High Availability Issues with BEA Tuxedo and Third Party High Availability Software".  While it's a pretty old white paper, from what I can see most of it is still applicable.

    What are the pros and cons of
    1) choosing to use the SAME
                                                  Apple ID for iCloud services on one side, and
                                                  purchases on the iTunes Store, App Store, and iBookstore, on the other side; or
    2) to have and use two separate Apple Ids for these "two sides"?
    P.S.
    I have loads and loads of free podcasts in iTunes in my iMac, that are certainly more thant the 5 gigas the iCloud provides for free, so I don't want those to go to the cloud. But this is perhaps a different question...
    Also need to mention that I have itunes on a mac, a pc and an iphone.
    Sorry to look so silly with this question, but I don't get the "big picture".

    You need to create a user account for your wife (or yourself depending on who has the current user account). When syncing, each of you should sign in as a separate user, login to iTunes and then sync. I had this problem when my sister got an iPhone. When we did her initial sync, everything on my iPhone showed up on hers. Apple gave me this solution.

    Hi Rajendra,
    The NetWeaver Installation Master Guide offers some good scenarios on the pros and cons:
    https://websmp201.sapag.de/~sapidb/011000358700005412792005E.pdf
    In a nutshell:
    ABAP+JAVA
    Pros
    - Decrease # of servers required to administer the portal
    - Less costly
    Cons
    - Upgrades could be dependent on ABAP and Java release level
    - Additional load on the server due to ABAP stack
    - Limited scalability
    JAVA and ABAP on separate server
    Pros
    - Improved performance
    - Allows each system to be single-use purpose therefore downtime does not affect other components
    - More scalable
    Cons
    - Adds complexity to landscape
    - Additional costs

  • What are the cause and fix for the following error message? NS_ERROR_FILE_ACCESS_DENIED failure code: 0x80520015

    Every time I close my Firefox browser I receive the following error message (see details below).
    FYI:
    -- I am running the current version of Firefox.
    -- I had no problems with this error message until my computer was recently attacked by 2 viruses:
    ` SystemFix
    ` Win7 Antivirus 2012
    Both viruses have since been cleaned from my computer. However, I am still receiving this error message.
    Here are my questions:
    * What are the cause and fix for this problem?
    * Do I need to uninstall and reinstall Firefox?
    * Is it possible that this error message is related to an add-on and that it has nothing to do with the recent virus attacks?

  • What are the Terms and Conditions for the AppleID

    What are the Terms and Conditions for the AppleID?   You know, those speed bumps you blow by when trying to achieve something.  Good luck trying to find them.  Apple has one place to take your money, many many different ways to tie you up with disparate Terms and Conditions.   They say that the fine print is important too.  So why are the terms and conditions for the AppleID so hard to find?

    Hi, Wanderer 37.  
    Thank you for visiting Apple Support Communities.  
    I absolutely understand your concern with having access to Terms and Conditions that you have accepted, and at Apple, we want this information to be as transparent as possible.  You can access the iTunes/Apple ID Terms and Conditions here:

  • I currently have a Macbook pro 10.6.8 and i'm interested software upgrade What are the advantages and disadvantages for upgrading my software.

    Ok... the only reason why i want to uprade my software is because of StarCraft 2. For those that don't know, Heart of the Swarm is coming out this March. I've been eagerly waiting for this expansion. I just read that SC2 HOTS will not be able to support any software below lion. I currently have 10.6.8 and i was wondering what are the disadvantages and advantages (aside from being able to play this expansion) of upgrading my software? Are there any draw backs, etc.

    Go all the way to Mountain Lion if you can...
    Upgrade to Mountain Lion
    But...
    Before attempting any Major Upgrade... get yourself an External Hard Drive... and create a Bootable Clone Backup of your current Hard Drive...
    By far the easiest way to make such a Backup, is to use something like
    SuperDuper  http://www.shirt-pocket.com/
    or CCC  http://www.bombich.com/
    That way, should anything untoward happen during the Upgrade,
    you will NOT LOSE ANYTHING.
    (Get an EHD that is at least equal to your current Drive...)
    Also, get more RAM...
    You can use this Link to check which RAM is suitable for your Mac...
    http://eshop.macsales.com/shop/apple/memory/
    It is Important to get the Correct and Matching RAM
    For best performance, fill all memory slots, installing an equal memory module in each slot.
    That site also has videos on how to Install RAM should you need it...

  • Upgrading from 10.4.11 to 10.7. What are the steps and do I also need to pay for 10.5 and 10.6 along the way?

    Hi. I wannt to upgrade from 10.4.11 to 10.7.
    What are the steps and do I also need to pay for 10.5 and 10.6 along the way?
    According to the 10.7 lion page on 'store' it says that you need 10.6 to use it does this mean I'm going to have to do 3 upgrades?
    Thanks

    Why do yoy want Lion/10.7???
    Anyway, if your Mac meets the requirements you can skip 10.5.x, and even 10.6.x if you can afford to erase all your data.
    Snow Leopard/10.6.x Requirements...
    General requirements
       * Mac computer with an Intel processor
        * 1GB of memory (I say 4GB at least)
        * 5GB of available disk space (I say 30GB at least)
        * DVD drive for installation
        * Some features require a compatible Internet service provider; fees may apply.
        * Some features require Apple’s MobileMe service; fees and terms apply.
    Which apps work with Mac OS X 10.6?...
    http://snowleopard.wikidot.com/
    It looks like they might still have it...
    http://store.apple.com/us/product/MC573Z/A?fnode=MTY1NDAzOA
    If it's a core Duo & not a Core2Duo, then it'll only run in 32 bit mode.
    Lion/101.7 System requirements
        •    x86-64 processor (Macs with an Intel Core 2 Duo, Intel Core i3, Intel Core i5, Intel Core i7, or Xeon processor.)
        •    At least 2GB of memory[14]
        •    Latest version of Mac OS X Snow Leopard (10.6.8), with the Mac App Store installed
        •    At least 4GB of disk space for downloading[14]
    Like Snow Leopard, Lion does not support PowerPC-based Macs (e.g., Power Macs, PowerBooks, iBooks, iMacs (G3-G5), eMacs).
    Lion also does not support 32-bit Intel Core Duo or Core Solo based Macs. Rosetta is no longer available in Lion, which means Lion no longer supports PowerPC applications.

  • What are the advantages and disadvantages for the larger blocksize and for

    What are the advantages and disadvantages for the larger blocksize and for the smaller blocksize?

    Smaller blocksize
    Advantages
    GoodHas relatively large space overhead due to metadata
    (that is, block header).
    Not recommended for large rows. There might only
    be a few rows stored for each block, or worse, row
    chaining if a single row does not fit into a block, for small rows with lots of random
    access.
    Reduces block contention.
    Disadvantages
    Has relatively large space overhead due to metadata
    (that is, block header).
    Not recommended for large rows. There might only
    be a few rows stored for each block, or worse, row
    chaining if a single row does not fit into a block.
    Larger blocksize
    Advantages
    Has lower overhead, so there is more
    room to store data.
    Permits reading a number of rows into
    the buffer cache with a single I/O
    (depending on row size and block size).
    Good for sequential access or very large
    rows (such as LOB data).
    Disadvantages
    Wastes space in the buffer cache, if you are doing
    random access to small rows and have a large block
    size. For example, with an 8 KB block size and 50
    byte row size, you waste 7,950 bytes in the buffer
    cache when doing random access.
    Not good for index blocks used in an OLTP
    environment, because they increase block contention
    on the index leaf blocks.

  • What are the advantages and disadvantages to cookies?

    Ok, so I am required to interview some expert for a Final in college. I choose to do my final on cookies throughout the different browsers. The downside is that it is nearly impossible to get a one-on-one interview from an expert in this field. This is my next option. So here are my questions, and I greatly appreciate the help.
    1. What are the advantages and disadvantages of cookies?
    2. Where are the cookies stored, and is it possible for someone to access that information?
    3. You hear horror stories of hackers accessing the different cookies saved on a person's computer, and from there gradually piecing together enough information about that person, to hack into nearly every account they have. How probable is this? What safeguards can a person take against this happening?
    Once again, thank you for any help received.

    I attended uni back in the 70's, and as I recall we had to do some actual research for our term papers - like from books in the library, and needed to "document" our research in a footnote for each page.

  • What are the uploads and downloads speeds

    what are the upload and download speeds of the time capsule?

    what are the upload and download speeds of the time capsule?
    If you are asking about Internet download and upload speeds, this is limited by your service plan with your Internet provider.
    It might be something like 10 Mbps download and 2 Mpbs upload, for example. That's because on most home plans, the download speeds are typically much faster than the upload speeds....unless you opt for a business type connection at significantly higher cost.
    The Time Capsule is capable of much faster speeds than your service provider can ever deliver, so the bottleneck on your network will always be the Internet connection...not the Time Capsule.
