Firewall Hardware is being replace (Discoverer 4i Impact) Oracle 11i

Hi there
We are going to replace Firewall Hardware from HP to Nokia, I have Oracle 11i and Discoverer 4i Plus/Viewer on Unix.
I have a question:
Is there any impact on Discoverer Plus/Viewer for chaning Hardware of Firewall?
Application Release 11.5.10.2
Oracle Discoverer 4i (4.1.48.08.00)
EUL V4.1.14.0.0.0
Oracle Database 10g (10.1.0.4.0)
Discoverer Plus 4i (4.1.48.08.00)
Thanks

Hi Asim
Well I'd certainly like to say No but recent experiences have led me to believe that a firewall can be one of the reasons for poor performance. Properly configure a firewall should not interfere with Discoverer but improperly configure I'm of the impression that a firewall can.
I'm working with two customers right now who have poor performance when Discoverer is situated inside a firewall. I've asked them to move it outside and see what happens. On one of them I started up my own application server, on my laptop of all places. The laptop was outside the firewall. When users ran reports connected to their own server, inside the firewall, I saw reports take 20 minutes. When the same user connected via my application server, the same report took less than 20 seconds. Therefore, more testing is required to ascertain whether the firewall is to blame, whether the network connection between the server and the database is at fault, or whether its just because the machine that is running the application server is just too old. I'll let you know as soon as I hear anything.
Therefore, I would certainly test out any new firewall before going live. I would recommend placing the application server inside and then outside the firewall and then conduct timing tests to see how long the workbooks take to run.
Best wishes
Michael

    Hi Gazpan,
    Thanks for visiting Apple Support Communities.
    I recommend using the steps in this article to back up your iPhone if possible:
    iOS: Back up and restore your iOS device with iCloud or iTunes
    http://support.apple.com/kb/ht1766
    You may also find this advice helpful for your situation:
    What to do before selling or giving away your iPhone, iPad, or iPod touch
    http://support.apple.com/kb/ht5661
    If you no longer have your iOS device
    If you're using iCloud and Find My iPhone on the device, you can erase the device remotely and remove it from your account by signing in to icloud.com/find, selecting the device, and clicking Erase. When the device has been erased, click Remove from Account.
    If you're unable to complete either of the above steps, you should change your Apple ID password. Changing your password won't remove any personal information that is cached on the device, but it will make sure that the new owner can't delete your information from iCloud.

  • Snow Leopard HD being replaced; my files are on external HD; can I run them off of MBA Lion?

    My Mac issues .... bad seagate hard drive .... , finally being replaced as of today by Apple store per the warranty. The MBA? All sorts of issues(el cheapo version--only $999 <insert evil smirk>; 2011 11-inch, measley 64G flash drive; memory keeps being eaten alive by some kind of "other" mystery files). Whatever. It's not like I'm not used to all the problems with this machine anyway ... so I'll hang on to it and try to work with it till Thursday.
    I've got both of my Macs backed up on a 1T Seagate external HD. With the 27-inch Mac in the Genius Hospital getting a new hard drive, I'd like to try to do one or both of the following:
    1. Work off of the iMac Snow Leopard stuff saved on the external hard drive (backed up ON the seagate external as well as on Time Machine--yes, it's journaled, whatever that means). Is that possible? There were very confusing issues with permissions that I was not able to resolve on my own before I took the Macs to the Apple store, so .... that brings me to Number 2.
    2. Since the idiot MBA has to have its hard drive wiped out for a fresh install on Thursday, can I wipe it out myself, OR just access the Snow Leopard files somehow off of the Seagate external drive? But they are only backed up via Time Machine, so it's what? Impossible to work with just one file, plus I've got those issues with disk permissions.
    I guess what I'm wondering is, can I use this MBA sort of as a temporary machine to run the Snow Leopard? I don't need everything off of the iMac, because I'm only talking about using it like this for today and tomorrow.  I'm more than happy to wipe out the entire contents of this MBA (it's backed up on the seagate external also) and just use it as Snow Leopard until I can get the iMac back and reinstall it all on there. Is that possible?
    I've googled until I'm blue in the face and my eyes have glazed over. I cannot figure it out. Obviously, this being the 11-inch MBA, there is no CD drive, so no way to boot off a Snow Leopard disk.
    Anyone? Buehler? Anyone? Can I work with my own files on that external drive, even if it means I wipe out the MBA?

    Can I do this?
    Only if your computer shipped with Mac OS X 10.4. Use the 10.4 package that shipped with it.
    How?
    Install it normally, considering the point above.
    Snow Leopard won't let me install an older version of OS.
    It's not Snow Leopard that won't let you. It's the computer itself.

  • Punctuation sometimes being replaced with "?" when published

    Hello,
    Every once in a while, when a page has been updated, most of the punctuation is being replaced with question marks (?).
    I've since gone in a second time and changed the question marks to the proper punctuation and the page published properly.
    Any thoughts?
    Thanks,

    I noticed on both of the pages, your charset is defined as:

    Please try changing it to UTF-8 and see if this resolves the problem:

  • My late 2009 iMac 27 inch hard drive just failed and is being replaced. It did not qualify for call back but I am wondering if there is others with similar issue

    As I stated my late 2009 iMac 27 inch hard drive failed and is being replaced.. I am being charged as machine does not qualify for the call back program..call backs are on 2011 machines.. However i am in shock that my segate internal iMac hard drive failed in less than two years.. are there others with similar issue? Also when I get machine back will new hard drive be stable .. How do I make sure my working environment is reliable.. I have all my data and work backed up and will be able to rebuild my system but I really do not want to have to go through this down the line again.

I may have finally solved a problem that I have seen a ton of people in all different types of discussions around the world having trouble with ...... I am going to upload some pictures of what I was getting in the beginning and it came out of no where .... I had the random pixel problem with my display and to make a long story short I came across an article two days ago regarding internal temperatures and fan speed ...... I kept reading about apples approach which is not the point  .....  More importantly I dug deeper into temperature control and fan settings .... I discovered all kinds of software and there is only one in my eyes that can help anyone dealing with this display problem .... I will be honest,  I do not have the money right now for anything extra and am barely getting by and that is why I kept at it ... I figured keep trying different things because  a repair is out of the question ... http://www.crystalidea.com/macs-fan-control   -   This program has solved my problem - I get to adjust three internal temperatures inside my Imac and slowly but surely as the temperatures remained constant the display is fine ....

Anyone that has any questions do not hesitate to contact me ...... I am going to upload some pics ....

  • Mail issue: received mail is being replaced by older mail from my inbox

    Some of my inbox received mail content is being replaced by older mail from my inbox.  Since I receive mail from my gmail account, I have to go there to check the mail which is not replaced.  An ideas/suggestions?

    Did it work correctly before now?
    Not certain, but this can fix myriad Mail problems...
    Safe Boot from the HD, (holding Shift key down at bootup),  it will try to repair your Disk Directory while the spinning radian is happening, so let it go, run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, then move this folder & file to the Desktop.
    Move this Folder to the Desktop...
    /Users/YourUserName/Library/Caches/Mail/
    Move this file to the Desktop...
    /Users/YourUserName/Library/Mail/Envelope Index
    Reboot.
    If that doesn't do it and you can afford to redo all your Rules, try these & reboot...
    /Users/YourUserName/Library/Mail/MessageRules.plist
    /Users/YourUserName/Library/Mail/MessageRules.plist.backup
    Note, in 10.5 & up /Users/YourUserName/Library/Caches/Mail/ may or may not exist.
    In Mail's Window Menu, choose Connection Doctor, any red dots for status, if so what is the message?
    Then click the Show Details button & Check again.

  • Messages, being retrieved via POP3, are having their alias being replaced by its primary smtp address

    We use a CRM tool (Deerfield's VisNetic Mailflow) that POP's into Exchange 2007 to access their mailboxes.  Senders of email to this mailbox use one of many alias' assigned to the mailbox.  The issue we are having is that the alias (ie secondary address) is being replaced by the mailbox's primary address.
    NB When I perform a test without POP'ing  (ie send\receive testing directly between a private external email address and my Exchange mailbox, back and forth), I am successful in retaining the secondary address.
    Any idea what is causing the address to change from the alias (ie secondary) to the primary address when POP'ing?  POP does seem to be the variable here...just not sure what I should be looking at in order to fix this issue.
    Regards,
    Andrew

    Following up on Andrew's post we're seeing some confirmation of a behaviour change in Exchange 2007:
    Dear Colin,
    Based on our lab test, it is confirmed that the behavior has changed in Exchange 2007. If a mail is received by Exchange 2007 store, the To field will remain as the intended recipient if you view the mail in Outlook 2003/2007. But the To header will always be changed to primary address if you view the mail in Windows Mail, Outlook Express via POP3 or IMAP. This is the reason that the same copy of a mail will exhibit the different address in header. In Exchange 2007, the real P2 address will be written to email to header only when it is transferred to MAPI format.
    Below is the final test report in our lab
    1: Exchange 2003 situation:
    Mailbox Name: Test1, Test2.
    Primary email address: [email protected], [email protected]
    Secondary email address: [email protected], [email protected]
    Use the Test1’s primary email address to send the message to its secondary email address and Test2’s secondary email address, then no matter which type of method we use to open these two mailboxes, the secondary email address will be listed in “to” field in this message’s message header. In the other word, the email address in the “to” field will not be changed to the recipient’s primary email address.
    2: Exchange 2007 situation:
    Mailbox Name: AA,BB.
    Primary email address: [email protected], [email protected]
    Secondary email address: [email protected], [email protected]
    use aa’s primary email address to send the message to its secondary email address and bb’s secondary email address, then if we use pop3 method to open the message, then we will see the recipient’s Primary email address in the “to” field in this message’s message header. However, if open the message by using Outlook MAPI method, then the recipient’s secondary email address in the “to” field in the message’s message header.
    In Exchange 2003 , if send the message to recipient’s secondary email address, then this secondary email address will be shown in the message’s message header without any change.
    However in Exchange 2007 situation, once you send the message to the recipient’s secondary email address, then open and view this message’s message header by Outlook MAPI, then the recipient’s secondary email address will still be shown in the “to” field. If we open and view this message’s message header by the POP3 or IMAP method, then the recipient’s primary email address will be shown in the “to” field in Message header instead of its secondary email address. This behavior is the new change in Exchange 2007 situation.
    Meanwhile, I have reviewed your replies again and I know that we open the message to your tickets message from the General delivery mailbox using Windows Mail on Vista and an IMAP connection. However, you opened the message to your person mailbox using Outlook 2007 on Vista using a MAPI connection. Hence, we will encounter two different behavior in “to” list in the message header.
    I understand that the VisNetic MailFlow application is probably a critical application in your organization. However, it seems this application work with POP3 or IMAP4 method. If so, it may not be able to get the secondary email address in the message’s message header. I am wondering if there is a MAPI versions of this utility so that it can recognize the original header.
    I hope my explanation can clarify this issue more explicitly. If you have any question about my explanation, please let me know.
    Thanks.
    Best regards,

  • Is TP/VS being replaced by SAP TM

    Is TP/VS being replaced by SAP TM?   What are the basic differences between TP/VS and SAP TM?

    Transportation Management is a  process to plan, optimize, and execute the complete transportation process between companies in a detailed manner. You execute transportation planning in SAP Advanced Planning and Optimization (SAP APO) using the component Transportation Planning/Vehicle Scheduling (TP/VS). The orders (sales orders, purchase orders, returns, or stock transport orders) and deliveries that you have created in SAP R/3 and transferred to SAP APO using SAP APO Core Interface (CIF) form the basis for planning.  The result of TP/VS planning are planned shipments that you transfer to SAP R/3 after planning is complete. There you use the SAP R/3 component Logistics Execution (LE) for transportation execution
