• I got a prob while creating a link/link between two tables in a jdeveloper11g

  Hi guys...

  I got a prob while creating a link/link between two tables in a jdeveloper11g, help me.

  I use two table employee, Department.

  Unfortunately there is no primary key and foreign key in these tables.now i updated on those of table structure.

  I want to create a form like it should be a link between the Department data, i.e. data and employee while the Department is changed then only present corresponding employees in this block...

  Table structure as follows

  Employee:

  -------------------

  employe_id,

  name,

  Department,

  GR,

  Date of birth

  Department of justice

  Department:

  --------------------

  department_id,

  department_name;

  Note: in the employee department table is the same as in the department table department_id...

  So, you want to build master / detail between Department & sub_departments?

  In the same way, create a new, yet another link between departments & sub_departments, so that the connection is:

  Department.Department_Id = sub_departments.department_id

• Create database link between two databases?

  Hi all
  
  Can someone tell me how to do?
  
  I have two databases in oracle 9i: 'mydb' & 'mydb1 '.
  
  mydb contains a table 'tab1' with a single domain (of the int data type) and mydb1 contains a table "tab2" with two fields (int, char).
  
  I tried to do this:
  
  System is one of the usernames and another username is olapsys
  Manager is the password of the system, and olapsys got the password = myolapsys
  
  I tried to create a link, but it gave me an error:
  
  CREATE DATABASE LINK mylink access the system identified by the Manager using "mydb.tab12";
  
  then I tried running this query in olapsys:
  
  Select * from tab12@mylink;
  
  Error:
  ORA-12154: TNS: could not resolve service name
  
  Help, please.
  
  Thank you and best regards,
  
  Lucky

  CREATE DATABASE LINK mylink to connect to the system identified by the Manager using "local service alias ';

  where local service alias is the name of the local service that you configured in the tnsnames.ora to connect to mydb1.

• TimesTen - Communication between two DSN

  Hello
  
  Currently I have a setup in Oracle DB in which there are two databases and objects are accessible in all of these databases via the link/synonyms database.
  
  Now, I need to replicate that in a Cache Timesten InMemory DB underlying of Oracle databases configuration that would involve the creation of a link between two DSN names stored on two different servers.
  
  Can you guide me on how to go about it.
  
  Thank you
  Karan

  Unfortunately there are several constraints here that aren't going to help you:

  1. when using the TimesTen "cache" feature a single TimesTen database can only cache data to a backend Oracle single instance. Only regular tables can be cached (not views, dblinks etc.). So, if you have two instances of Oracle Db and you need data in cache at the same time you will need two TimesTen databases.

  2. as mentioned, TimesTen does not support dblinks, remote queries or queries/transactions distributed between various databases TimesTen (well, what he does in some circumstances, but anything that will help you I think).

  3 TimesTen can replicate data between different databases TimesTen, but in general you can not use the level replication table with cache tables.

  So I think, to adopt TimesTen in your application as an important architectural work may be necessary. Only you can be the judge of that, of course, but considering this please keep in mind the constraints above.

  Kind regards

• Link between CHMS

  I want to create a link between two ECMS who reside in the same directory of the table of contents. For example, just for context, I have the following:
  Link 1
  Link 2
  Link 3
  
  3 link links to a remote subject. The link opens correctly in the right pane of the CHM, but I want the link to open the second help CHM, does not open in the same frame.
  
  I chose the new window in the properties of the table of contents but still no luck.

  Hi, TechWriter77,

  You can do this by linking the table of contents entry to a topic that, when opening, fires a shortcut command to the second file .chm open. See the example below.

  I think that Rick also covers this in her file tips and tricks ('Launch HTML Help shortcuts in the table of contents/Index' and 'external launch.) CHMS").

• making data transfer between two computers

  Hello

  I developed a labview for data acquisition goal program.  I need to run a part of my program in a computer and some said in another separate computer. for data transfer between these two computers, I decided to use the Protocol of data taking. a computer, collect data and send data to the second computer and second computer will control the setting of data acquisition in the first computer. now I have developed the program but it does not work. I wonder if that is enough to link these two PC by a network cable or something needs to be done. of course, I have some problems with the source definition in the Protocol of data taking. need two labview program in two separate computers.

  Best regards.

  the problem is resolved.

  transfer of data from socket, simply connect two computers with a LAN cable, as I did. The problem is the URL parameter. I got the error as follows:

  ==> in main and remote program, the URL must be the same and the computer name that data socket server is running must be incloded in the two URLS. (my mistake was that I had used two different URLS in the main program and remote). either way, I realized that this isn't neceessary to Server execution data socket in the two computer.but that that send data.

• The way of writing to a wireless bridge between two different routers.1:broadband and dir 2:dlink 605 l

  I want to bridge.and wireless I can't do that... Please send me how to write to a wireless bridge between two different routers.

  1:broadband
  and
  2:Dlink dir 605 l,

  Hi Mohammed Ehsan Jourah,.

  Thanks for posting the request in the Microsoft community forums.
  I understand that you need to know how to make a wireless bridge between two different routers

  What version of the operating system is installed on the computer?

  To connect multiple computers, install a network adapter in each and run a network CAT5 cabling to connect each one to a hub (and thus the other.) The computer that will serve as a transition will have a standard network card for wired and a wireless network adapter that will connect to the wireless (WAP) access point or gateway on the second network.

  A network bridge is software or hardware that connects two networks or more so that they can communicate. You can create only a single bridge network on a computer, but a bridge can handle any number of network connections.

  You can try the steps at the bridge between two different routers wireless.
  a. determine the coverage area. When using two or more routers, the coverage area should be divided, and each router should be placed in a central location in each subdivision. If you add a wireless router to an existing network, this may mean moving the first router.
  b. decide which router is the main router. The main router is connected to the Internet, a LAN cable or other networks. It should be as close to the wired network connections or who has the best line of sight to another wireless network. In addition, the main router should be a high range router, allowing large tables of State and more users.
  c. buy a spare antenna, as the antennas that come with most routers do not have very good range. Quality omnidirectional antennas can push the range and signal strength of each of the routers, which, in turn, will reduce the cost by allowing routers less cover more space overall.
  d. deploy the primary router carefully. This router is the most important and requires most of the time of installation and options. Set the WEP (Protocol) encryption Service Set Identifier (SSID) and wireless, set up the Internet connection and test the router with some clients (computers). Once you get the main router deployed, deploy other routers should be easy.
  e. deploy the secondary routers, which must be configured to operate in "mode of transition." Secondary routers should be deployed around the perimeter of a large area or 'hot spots' where users placed - for example, will convene a bench Park or the table.

• The DDE network between two PCs running windows server 2003

  We seek to transfer data between two excellent sheets (Office 2003). Two excellent books are on different PCs running windows server 2003 and office 2003. The two PC's belonging to the same workgroup. One of them being run by Siemens PCs 7 process control system. I have ensurred running on both PC Netdde.exe. When excellent both books are on the same server they connect perfectly. When I run the client excel book on the other Pc (without changing something in the formulas of cells) the connection is lost. The DDE connection is approved on the PC server and this connection permission is full control for everyone. What is perhaps the reason for this problem? I think I missed a point. Can I get help for this. Thanks in advance for you.

• "Limited connection" when you configure the network between two computers XP.

  Original title: Configuration of the network connection

  Trying to establish a network connection between two home PCs., both running Windows XP Pro. Have been through the network on both PC Setup Wizard but, they still say limited, in fact no connection. I use an Ethernet cable between the two Crusader. If it is true what I'm doing wrong?

  Thanx Terry

  Old but good, networking tips from MVP Malke, MS:

  The best and simplest is to buy a wireless router. This way you get Internet connectivity both machines and the added benefit of security more between you and the Internet. Then you configure your network wireless safely, and then you configure file/printer sharing. Here is information on the implementation of a router and also in networking. It seems long, but don't be intimidated. Setting up a router and the LAN of sharing between two computers takes about 15 minutes.

  The router configuration

  Setting up a router is simple enough. Normally, you run the CD that came with the router and follow the instructions. If you're running Vista, maybe the CD that came with the router does not work; I do not know this. But you can set up the router without the CD. Note that if you have Internet cable for the connection you have just set up the router to DHCP (or there may even be a choice of cable to choose). If you have DSL Internet, you select TRP usually and enter the username and password you selected when you initially set the DSL connection. So:

  1. turn off the power to your cable modem.

  2. attach a cable (usually supplied with the router) course Ethernet cat5e Internet/WAN port of the router to the Ethernet port on the cable modem.

  3. connect the ethernet cable cat5e from the network card in your computer to one of the ports on the router. If you do not have an ethernet cable (because you were using USB), you will need to go to the store and buy a.

  4. turn on the cable modem. After that all the lights are on, turn on the router.

  To configure the router:

   

  Have a computer connected to the router with an ethernet cable. Examples given are for a Linksys router. See the manual of your router or the router mftr's Web site. for the parameters by default if you don't have a Linksys. Open a browser such as Internet Explorer or Firefox and in the address bar type:

  http://192.168.1.1 [Enter] (it is default IP address of the router, which varies from router to router then check your manual)

  This will bring you to the login screen of the router. The default username is blank and the Linksys default password is "admin" without the quotes. Enter this information. You are now in the configuration of the router utility. Your configuration utility may be slightly different from mine.

  Click the Administration link at the top of the page. Enter your new password. MAKE A NOTE SOMEWHERE THAT YOU WILL NOT LOSE. Re-enter the password to confirm it, and then click Save settings at the bottom of the page. The router will reboot and show you the box of connection again. Do not fill in the user name and put it in your new password to enter the configuration utility.

  Now, click on the link wireless at the top of the page. Change the network name (SSID) wireless by default to something, you'll recognize. I suggest that my clients not use their surname as the SSID. For example, you might want to name your network wireless network "CastleAnthrax" or similar.

  Click on save settings and when you get the prompt that your changes were successful, click the wireless security link which is just beside the Basic Wireless Settings link (where you changed your SSID). If you have a newish computer, you will be able to affect security WPA2-Personal Mode. Do this and enter a password. The password is what you enter on all computers that are allowed to connect to the wireless network. MAKE A NOTE SOMEWHERE THAT YOU WILL NOT LOSE.

  At this point, your router is set up and if the computer that you use to configure the router will normally connect wireless, disconnect the Ethernet cable and wireless of the computer should see your new network. Enter the password you created to join the network and start surfing.

  B. file/printer sharing of

  Excellent, comprehensive, but easy to understand article on sharing files/printer under Vista. Contains information about sharing printers and files, and the folders:

  http://TechNet.Microsoft.com/en-us/library/bb727037.aspx

  For XP, start by running the Network Setup Wizard the on all machines (see warning in section A below).

  Problems sharing files between computers on a network are usually caused by 1) a misconfigured firewall or a firewall neglected (including a dynamic firewall in a virtual private network); or (2) inadvertently run two firewalls such as the firewall of Windows and a third-party firewall. and/or (3) do not have accounts to the same users and passwords on all computers in the workgroup. (4) tries to create actions where the operating system does not.

  A. configure the firewall on all machines to allow traffic to local area network (LAN) as being approved. With the Windows Firewall, it means which allows file sharing / print on the Exceptions tab normally run the XP Network Setup Wizard will take care of this for these machines. The only "witch hunt", it will turn on the XPSP2 Windows Firewall. If you are not running a third-party firewall or you have an antivirus with "Internet Worm Protection" (like Norton 2006/07) which acts as a firewall, you're fine.  With a third-party firewall, I usually set up the allocation of LAN with an IP address range. E.g. would be 192.168.1.0 - 192.168.1.254. Obviously you would substitute your correct subnet. Do not run more than one firewall. DON'T STOP FIREWALLS; CONFIGURE THEM CORRECTLY.

  (B) to facilitate the Organization, put all computers in the same workgroup. This is done from the System applet in Control Panel, the computer name tab.

  C. create the counterpart of the user accounts and passwords on all machines. You do not need to be logged into the same account on all machines and assigned to each user account passwords can be different; accounts/passwords just need to exist and to match on all machines. DO NOT NEGLECT TO CREATE PASSWORDS, EVEN IF ONLY OF SIMPLE. If you want a machine to boot directly to the desktop (a particular user account) for convenience, you can do this. The instructions on this link work for XP and Vista:

  Set up Windows to automatically connect (MVP Ramesh) - http://windowsxp.mvps.org/Autologon.htm

  D. Si one or more of the computers is XP Pro or Media Center, turn off Simple file sharing (Folder Options > view tab).

  E. create share as you wish. XP Home does not share the users directory or the Program Files, but you can share folders inside those directories. A better choice is to simply use the Shared Documents folder. See the first link above for more information on Vista sharing.

  F. you have the job of file sharing (and tested by exchanging a file between machines), if you want to share a printer connected locally to one of your computers, share of this machine. Then go to the printer mftr Web site. and download the latest drivers for the correct system. Install them on the target machines. The printer must be collected during the installation procedure. If this isn't the case, install the drivers and then use the Add Printer Wizard. In some cases, printers must be installed as local printers, but it is outside this response.

• is it possible to establish a direct connection between two computers, one running on windows xp sp2 and other running on windows xp sp3?

  Hello
  I connected two computers, one running on windows xp sp2 and others running on windows xp sp3 via com using RS232 port via link Modem DFM-562E ++.
  I am able to dial numbers from a PC successfully.
  But when I do a direct link between them (one as a host, the other guest) through the com port, I get error 777.
  Is this because the two PC's using different service packs?
  Help, please.
  Thank you & best regards
  Ravi

  It is not the service pack - although you should have installed sp3 now.

  Your message is not clear: have you been able to connect successfully computers using your modem D-Link?  How did you do that?  Will there be a modem in the second computer?

  What cable are you using to establish a direct connection between the com ports on both computers?  If you have purchased this cable online, please provide a link to the site where you bought it.

  Please describe the physical connection between the two computers.  For example, this is how you connect to the Internet by dial-up services:

  computer 1-{(9 broches) RS-232 serial port}-{RS-232 cable supplied with the modem}-{modem}-{phone cord (RJ-11 modular plugs at each end)}-{telephone wall jack}

• Which fibre to be used between two server rooms for 7048

  I'm looking to install a new core network for two rooms of small servers and using the 7048 Powerconnect switch in a fireplace in each room.  I'm not sure that the best way to connect well.  Two server rooms are distant of about 40 m and I leave the fiber principle would be preferential over copper that distance and it would be less sensitive to interference.  I think I can put the optional Modules of 10 GB with SFP ports + in of the 7048, but I don't know what transceivers or fiber should I use for a 10 GB connection?, any idea or any recommendation please? Or if I should do something else.

  Fiber is a great reliable way to connect the two switches without removing your copper ports. Here is some info on the transceivers that I listed for the 7048.

  Transceivers

  The part number, WTRD1, SFP + SR optical, 10GbE

  Multiplayer, 850nm, multimode 62.5 micron fiber, it has a maximum range of 26 meters of cabling

  The part number, RN84N, optical SFP + LR, 10GbE

  Single mode, 1310nm, 10GBASE-LR has a scope specified 10 kilometres

  The part number, DT87G, SFP + LRM optical, 10GbE

  Long Reach Multimode, 1310nm, 10GBASE-LRM supports distances up to 220 metres (720 ft)

  Talk with your sales representative will be the best way to know which parts are easily available in your region and then your financial objective of businesses.

  Another option if you have available copper ports is TROLLING to several ports set to post a link between switches. This will give you a redundancy, but not the speed of 10 GbE.

• Vs LACP LAG between two PowerConnect 5448 s

  Hi all.

  Just got a switch configuration quad for our infrastructure EqualLogic SAN using PowerConnect 5448 s.  One thing I never did before her configuration of aggregation of links.

  If I wanted to set up an aggregate of 4-port connection between two switches, say on ports 1 to 4, and our iSCSI VLANS is 1000, the below will work?

  serial interface ethernet g(1-4)

  channel-group mode 1 on

  interface port-channel 1

  switchport general

  switchport General pvid 1000

  I've seen documentation on how to get the ports-working channels between a 5000 or 6000 switch and a Cisco Catalyst switch, but not just any what docs on how to connect two switches PowerConnect.  The doc of interoperability for Cisco <->Dell seems to want to use LACP on the side of Dell.  I wonder, should I configure and link LACP on the two 5448 aggregate s I have are running?

  Thanks for in advance for any advice or assistance!
