Yep, also remember stuff like this *never* gets updated (unless you want to buy a new HVAC system anyway!), so while it may be on Win7 and fine today, start planning for the future when Win 7  is no longer supported but this HVAC system still exists so setup segregation today while you remember.
Very true, it has been running for some time now, and while they do perform maintainance but I doubt that also includes the system software/applications.

A while back a heating system was installed at our company. Things were implemented in such way that the supplier has access to the heating system via the internet to manage and monitor it.Keeping in mind it is "just" a heating system, and a visitor from the outside cannot see which we are using, I figured the risks (at that time) were minimal and allowed access via a certain port on the firewall.A similar situation has been brought up, but now regarding a new alarm system. And I am starting to doubt wether such a device should be accessible from the internet. So I advised against it, and stated I would suggest to only have it accessible via the local network. If somebody has to use it from the outside, they can login to our network via VPN and access it from there.If I allow more and more devices to access internet or to be accessed...

  • How to deal with credentials for external applications using a Java Client/

    Hi Guys,
    This is the case. I am integrating an external application with an ADF Application. I have implemented some programmatic ViewObjects that are being filled up by a REST Java Client Wrapper. Everything is working fine but the issue is that the credentials the wrapper is using are hard coded inside the java class. I am thinking to ask for the credentials at the beginning of my taskflow and then store them somewhere and use them then to create my client wrapper (passing them in the constructor).
    However, I don't know if my approach is good and I would like you to share your experiences or how to deal with this.
    Regards

    You can use Credential Store Framework to store the credentials securely in the weblogic server instead of hardcoding in the java class.
    The Credential Store Framework:
    - enables you to manage credentials securely
    - provides an API for storage, retrieval, and maintenance of credentials in different back-end repositories
    Check the documentation on CSF API -
    http://docs.oracle.com/cd/E29505_01/core.1111/e10043/devcsf.htm
    Major Steps -
    1. Create a credential map and key in em console to store the password (http://docs.oracle.com/cd/E25054_01/core.1111/e10043/csfadmin.htm)
    2. Use CSF API to retrieve the stored password
    3. In jazn-data.xml give permissions to access CSF key and map

  • How to deal with dynamic IP address changes

    I have installed Fodero C3 and Oracle 10g successfully. Oracle 10g use web OEM console to manage database. However, my internet provider only provided me a dynamic IP address. When I installed Fedora C3, Linux server automatically picked a Hostname like " ip12-345-678-90.dc.dc.cox.net". After I created database, all database files also used this hostname. Then Oracle web OEM console worked fine. Due to the dynamic IP address assigned by ISP, their DHCP server changed the first part of IP address(ip12-345-678-90)frequently to another one. After IP address changed, I couldn't start up web OEM console and listener because they couldn't find correct hostname (IP address). I have talked to my ISP. It seems that it can not be solved. Anyone knows how to deal with this problem through 10g and OEM console themseleves. I also think about to configure Linux server to solve the problem. I really need your help. Thanks in advance

    Thank all of you so much to respond my questions. I think I have solved the problem. Since the key point was that Oracle 10g OEM console could not work with the frequent changes of IP address made by my ISP. I just bought a 54G wireless router. Then connecting router to cable modem. The cable modem still gets the dynamic IP from ISP, but the router automatically assigned a static IP address to my Linux system with the range from 192.168.0.0 - 192.168.255.255. This IP was control by my router. It is nothing to do with ISP. So I re-created Oracle database with this new static IP. Then OEM console and listener can startup and connect to database without problem. I do think other guru's methods also will work. I just have no time to try them one by one. Thanks again. Your inputs make me learn many things.

  • Move of mailbox with over 30K of folders fails, how to deal with this.

    Hello all,
    I'm in the process of moving all Exchange 2010 mailboxes to newly created databases located on new storage.
    Every mailbox except one moved successfully, the "problem" mailbox keeps failing and I need some advise on how to deal with this.
    The mailbox that keeps failing is only 4 GB but has over 30K of folders that the users created manually over the years.
    They are unable to easelly delete folders as they have created many sub folders within the folders.
    I posted a part of the failed move request log below.
    Can anyone advise on how to solve this?
    Thanks in advance.

    Hi,
    Based on the description, please run the following commands to check if there are any message limit size. Try to increase the limit size then move this mailbox.
    Get-mailbox –identity “user name” | fl MaxSendSize,MaxReceiveSize
    Get-transportconfig | fl MaxSendSize,MaxReceiveSize
    Get-transportrule | fl MessageSizeOver
    Get-sendconnector | fl MaxMessageSize
    Get-receiveconnector | fl MaxMessageSize
    Note: Once we increased the value we need to wait for the AD replication and cache to be cleared and then test the move mailbox.
    If this doesn’t work, please try to move mailbox with the skip corrupted items. This will skip the corrupted items and move only the good items to the target mailbox.

  • How to deal with visession in IVI-C driver program ?

    a ViSession is an identifier that corresponds to a session.
    My instrument is a remote internet device . i can call VISA library to implement
    communication between labwindows and my remote internet device.In this case , what is meaning of Visession
    ? It looks as if Visession does not have a relation to my IVI-C driver program.
    if it has a relation to my driver, how to deal with the ViSession in IVI-C driver program?thank you

    ViSession is necessary as part of a larger picture and fills an important role in good architecture.  Intrument handles (stored as the ViSession type) are necessary for large projects, which may require commanding multiple instruments.
    There is no function to call which can get or set a ViSession value, similar to the way other attributes are set with driver functions.  The ViSession intrument handle is created and returned to the application when an instrument is initialized; it represents a connection with one particular instrument.
    This allows users to have multiple instruments connected, which can be controlled programmatically with one application.  Then, the application can quickly specify which instrument it would like to send a command, just by sending one instrument handle or another.
    Yes, you could remove the ViSession as parameter in your functions, but it would cripple the big picture effectiveness of the driver.  In place of the ViSession, you would have to send each function the Resource Name or Resource ID for the particular instrument as well as the Option String.  So really, it is just more practical and better practice to use an instrument handle (stored as the ViSession type).
    That being said, for certain functionality (adding two numbers), you absolutely do not need a ViSession instrument handle parameter.  You will have to use your best judgement to determine where to include or exclude this parameter.  I suggest using the ViSession instrument handle parameter with any function that communicates with an instrument.
    Also, Ebalci is correct regarding the difference between ViSessions and channels.  ViSessions are used to communicate with different instruments.  To reference or read a specific channel from an instrument you will have to refer to the guidance in the manual for the instrument in question.  There will likely be a command to select a specific channel when reading from the instrument.  And for general guidance, I suggest reviewing another IVI driver, possibly for an instrument of the same class or type or maybe from the same family, if such a driver already exists.

  • How to deal with deadlock on wwv_flow_data table when http server times out

    There are some threads about a deadlock on the wwv_flow_data table. None of them contain a real explanation for this behaviour. In my case I will try to explain what I think is happening. Maybe it helps somebody who is hitting the same matter.
    In my case with APEX 3.2.1 I am navigating from one page to another. Doing this APEX will lock the table wwv_flow_data. As soon as the other page is shown the lock will be released. But now this other page contains a bad performing query (standaard report region). After 5 minutes the http server (modplsql) will time out and present the message "No response from the application server" on the screen. In the meanwhile the query is still running on the database server and the lock stays on the wwv_flow_data table.
    Normal user behaviour will be that the user will use the back button to return to the previous page and tries it again to navigate to the other page or
    the user will try to refresh the page with the bad performing query.
    And voila now you will have a deadlock on the wwv_flow_data table since a second session is trying to do the same thing while the first hasn't finished yet.
    How to deal with it?
    First of all. Have a good look at the bad performing query. Maybe you can improve it that it will succeed before the http server will timeout.
    In my case the 11gr1 optimizer couldn't handle a subquery factoring clause in the best way. After changing it back to a classical inline query the problem was solved.
    Secondly you could increase the timeout parameter of the http server. Although this not the best way.
    Maybe it would better if APEX in a next version would release the lock on the table wwv_flow_date earlier or do a rollback just before the moment that the http server is timing out.

    Hello Shmoove,
    I saw your reply here and you probably understand the problems the HTTP 100 response may cause.
    I am trying to send image that was taken by getSnapshot. The problem is that the server respond with this HTTP 100 message.
    I suspect that the reason that my server doesn't recognize the file that I'm sending from J2me is that the "server to client" response to the 100 message comes after the second message of (see what the TCPIP viewer shows down here):
    POST /up01/up02.aspx HTTP/1.1

  • How to deal with OpenCL grey out issue.

    First off, I'm not native english speaker.
    I have Nvidia GeForce 550 Ti video card, and its support OpenCL v1.1.
    I'm also face a "random" OpenCL grey out issue like other people here, but I found the "issue" and how to deal with.
    open a command windows (using WinKey + R, and type cmd <enter>)
    type "cd C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)" <enter>
    type "sniffer_gpu" <enter>  -->> to check your GPU has OpenCL in Photoshop?
    When GPU is in power-saving mode (core running in 51Mhz, using MSI Afterburner monitor), I running sniffer_gpu, got this report
    C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)>sniffer_gpu
    Device: 0000000000328D68 has video RAM(MB): 1023
    Vendor string:    NVIDIA Corporation
    Renderer string:  GeForce GTX 550 Ti/PCIe/SSE2
    Version string:   3.0.0
    OpenGL version as determined by Extensionator...
    OpenGL Version 3.0
    Has NPOT support: TRUE
    Has Framebuffer Object Extension support: TRUE
    OpenGL ok
    Return code: 1
    C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)>
    No OpenCL support
    Then, I switch GPU back to normal status (core running at 900Mhz)
    C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)>sniffer_gpu
    Device: 00000000001F8D68 has video RAM(MB): 1023
    Vendor string:    NVIDIA Corporation
    Renderer string:  GeForce GTX 550 Ti/PCIe/SSE2
    Version string:   3.0.0
    OpenGL version as determined by Extensionator...
    OpenGL Version 3.0
    Has NPOT support: TRUE
    Has Framebuffer Object Extension support: TRUE
    OpenGL ok
    OpenCL ok, version=1.1 CUDA 4.2.1
    Return code: 3
    C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)>
    OpenCL support !!
    Nowadays, most of new GPUs were support power-saving, but when sniffer_gpu running at GPU power-saving state, the OpenCL computing report maybe "time-out", cause the detector "guess" the GPU does not support OpenCL. This is why many people says "OpenCL" sometimes work, sometimes grey-out.
    I hope this bug can be fixed, or at least people can understand how to "enable OpenCL everytime when you launch photoshop".
    Bye.

  • How to deal with "Error 1001. The specified service already exists" when install a service using installer package?

    Hi everybody,
    I wrote a "Class Library" project which is a service using Visual Stodio 2008 recently, then tried to use a Visual Studio 2008
    Setup Project to install it.
    Here is what I did for the "Class Library":
    1. Finish the program.cs, Service.cs
    2. Add Installer
    3. Change the serviceInstaller so that "StartType" to be Aotumatic
    4. Change the ServiceProcessInstaller2 so that "Account" to be LocalSystem
    5.
    6. Click in F5 (Start Debugging)
    Here is what I did for the Setup Project:
    1. Add the exe file built from the "Class Library" project to the Application Folder
    2. On the Custom Action Editor, add the exe file from 1 to Install and Commit
    3. Change the property of the project so that "RemovePreviousVersion" to be true
    4. Click on F6(Build Solution)
    Then I tried to run the msi file from the built of the Setup Project. Because I modified the two projects serveral times, I uninstalled the Class Library using "Control Panel->Add or Remove Programs" before I reinstall. Two things I notived:
    1. After unstall, the registry was not cleaned up about the installed program
    2. After several rounds install/uninstall, I got "Error 1001. The specified service already exists"
    My questions are:
    1. How to cleanup the registry when uninstall a program?
    2. How to deal with the "Error 1001. The specified service already exists"?
    3. Did I do anytbing wrong with the "Class Library" or the "Setup Project"?
    Thanks a lot!

    Hi Simon, not a problem!
    I spent some more time on this and here are few more notes:
    it is called Major Upgrade, when you are installing new version of the product upon a previous one and
    MSI supports 2 strategies:
    Strategy 1. Install a new version and uninstall previous one. (Install a new version right upon previously installed version (file merging is performed based on dll version number) and the delete previously
    installed files)
    Strategy 2. Uninstall previous version and install a new one (Delete all previous files and install from scratch new files.)
    From the first look it seems that 1st strategy is weird and buggy. But, remember, MSI is great because it's transactional!!! That means that if once some of the phases (Installation, Uninstallation, Rollback, Comit) fails, your machine
    will be reverted to the previous state and it'll be still functional. 
    Let's consider both strategies:
    Consider you have installed product_v1.msi and you want to install product_v2.msi.
    Strategy 1
    1. MSI engine copies files from Product_v1 directory to TEMP directory
    2. MSI engine merges files based on the assembly version (between v1 and v2)
    3. Once merging is completed successfully it removes files in TEMP (RemoveExistingProducts  action triggers it) and you got product_v2 installed, otherwise if it fails MSI engine revert machine to V1 and copies previous files from TEMP.
    Strategy 2
    1. MSI engine tottaly removes all files from v1.
    2. MSI engine installs v2 files and if something goes wrong you cannot revert back, because RemoveExistingProducts  allready worked out and MSI doesn't have files to revert machine back
    I recommend to everybody to use Strategy 1 and leverage MSI transaction functionality. And you can set this strategies by defining sequence of RemoveExistingProducts action. See more info
    here.  So, I think it's not even a bug in VS as I said in the upper post it is default recommened behaviour.
    AND, you got "Error 1001. The specified service already exists"
    because if we follow Strategy 1 MSI engine tries to install Windows Service on top of the existing service and OF COURSE it fails MSI engine (StopServices, DeleteServices actions are executed before actual
    installation and  they look at ServiceControl table). In order to stop service first and delete them you have to fill ServiceContol table of the MSI (and then StopServices, DeleteServices actions will recognize what to they have to stop
    and delete), like this:
    *clip*clip*clip*
    ' see http://msdn.microsoft.com/en-us/library/windows/desktop/aa371634(v=vs.85).aspx for more info
    ' Update the Service Entry to stop and delete service while uninstalling
    query = "INSERT INTO ServiceControl (ServiceControl, Name, Event, Arguments, Wait, Component_) VALUES ('MAD_Service', 'Service name', '160', '', '1', '"
    + componentName + "')"
    Set view = database.OpenView(query)
    : CheckError
    view.Execute : CheckError
    ' Update the Service Entry to stop and delete service while installing
    query = "INSERT INTO ServiceControl (ServiceControl, Name, Event, Arguments, Wait, Component_) VALUES ('MAD2_Service', 'Service name', '10', '', '1', '"
    + componentName + "')"
    Set view = database.OpenView(query)
    : CheckError
    view.Execute : CheckError
    *clip*clip*clip*
    We can uninstall service first by following Strategy 2, but then we lose transactional support.
    So, Simon did I encourage you to change your code a bit?:)
    And, btw, if you don't want to change the strategy, please don't rely on SequenceID in MSI table, it can be change, you have to get the at the runtime.
    Hope it will help to everybody!

  • How to deal with payment of vendor to us (credit notes I guess)

    Normally I use F07 for outgoing payments, it's linked to vendors, but how to deal with incoming payments of vendors?
    We got paid two invoices(credit notes I guess) and I want to put them under the right vendor, but how do I do it?
    I can't use F07 I think because I need to use positive amounts (for normal purchase invoices) and can't use negative amounts in this transaction. F08 is for ingoing payment but that session is linked to customers I thought..not for vendors?
    How to deal with this kind ot transactions? What transaction can I use the best for payments like this
    (we got paid an amount , no invoices yet, but I know the vendor).

    whith F-02 it is possible I noticed.

    Hi Kamlesh,
    Thanks for your response.
    Actually, In the "Process External Bank Statement" window, i see that there are few entries which is for the previous year and which has not been reconciled. I have never worked practically on BRS and hence, i am scared to make any changes in the clients database without being confident on what i am doing. I need to reconcile for one of their Bank a/c for the month of April '08. I have the copy of the statements for the month ending 31st Mar 08 and 30th Apr 08. The closing balances are as below:
    31/03/08 - 2300000.00
    30/04/08 - 3100000.00
    Now my OB for Bank a/c for April '08 in SAP is 2300000.00 Dr.
    When i go to External Bank Reconciliation - Selection Criteria Screen (Manual Reconciliation), here are the detail that i enter:
    Last Balance: INR -7,000,000.00000 (Grayed out by the system)
    Ending Balance: INR -3,100,000.00000 (Entered by me)

    "Reconciliation Bank Statement" Screen opens up and shows the below balances in the screen:
    Cleared Book Balance: INR -7,000,000.00000
    Statement Ending Balance: INR -3,100,000.00000
    Difference: INR 3,800,000.00000
    As per the Bank statement, i have found all the transactions listed out here for the month of Apr '08 but, i also found that the open transactions for the previous month from April '08 have been lying in "Process External Bank Statement" window.
    Could you please help me solve my issue as to what needs to be done or could you also get me some links from where i can get few documents for processing External Bank Reconciliations?
    That will be of a great help for me. I need steps as to what needs to be done first and then the next so that i can arrive at the correct closing balance for the month April '08.
    Thanks in Advance....

    Hi,All,I need your help!
    if an organizational unit has been transfered to another upper organizational unit ,and there are already persons assigned to different positions of it,so how to deal with this problem?are those person's IT 0000,0001should be changed too?and how to maintain this kind of change?is a personnel action necessary?or there is some other more efficient way for it?

    Hi
    In IT0001 You have a Position which is linked to a Org unit. If you want to change the org units reporting relationship then you have to change it in OM by creating a new relationship with the upper org unit.
    All the person are assigned to position so nothing needs to be done in  PA.
    Reward points if useful.

  • IMac SSD full - how to deal with the two drives

    Greetings all,
    I've been using an iMac i7 with two drives SSC and HDD.  Recently, I've been having issues with the SSD being close to full.  I use it for applications only, although some apps need lots of space (iTunes, iMovie, Photoshop, etc.)  I use Lightroom and have all the images on the spinning drive.  Does anyone know how to deal with this issue?  Any way I can move the music from iTunes to the separate drive, or any way to figure out what exactly is using most of my space?
    Thanks in advance for your help.

    Every tables are growing in any applications. In some applications, tables become larger and larger quickly. How to deal with this problem?
    I am developing an application system now. Should I add a lot of delete commands in the code for each table?

    I am developing an application system now. Should I add a lot of delete commands in the code for each table?Uh, well, yes if you continually add rows to a table the table will grow ... sooner or later you will want to delete rows that are no longer needed. What did you expect? You have to decide what the business rules are to determine when a row can be deleted, and make sure your design allows for such rows to be identified. This is called ..... analysis and design.
