• Copy of the object between two databases

  Hi, in SQLDeveloper I can copy the objects 'tools-> copy of database... "between two databases such as (tables, views, indexes, triggers, constraints, etc, etc...), but how can I do it with SYNONYMS and GRANT of the object? Thanks for your help.

  You can watch the cart (view > trolley).

  The cart can generate a script to include SUBSIDIES, and you must add synonyms. You can then run these scripts in your target database.

  Drag the table to your shopping cart. Add synonyms.

• 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,

  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.

  Ok. You will need to ensure that the ip addresses you assign to your virtual machines are in the same subnet that the adapter created by the installation of vmware. Once you get the fixed basic network installation, you can treat these virtual machines like any machine in your data center. Forget the vm console and access it exactly as you would for any remote server - putty for the Linux and Windows Remote Desktop to the Windows machine.

  To a prompt on the host computer, post this:

  c:> ipconfig -all
  

  You will get feedback on multiple net cards, of which two are identified as with vmware - vmNet1 and vmNet8. Note the IP addresses of the two. We'll need later.
  You'll also need to know how you have configured the network cards on your virtual machine - NAT, bridged, hostonly?

  Note that these issues are out of scope for this forum. I don't mind helping, but I don't have an installation of vmware for details of the reference.

  Which have really tried to do? ( Data transfer )

  It's pretty vague. Exactly how did you try to "Exchange data"? A SQL using a db_link? import/export? Pigeons?

  I don't know, how to set up the ip address and the necessary information for the windows database.

  Configuration of an IP address is purely a matter of admin OS and out of range for this database forum.

• Synchronization between two databases with only 2% of the data; Please help me

  Hi all
  
  I have two oracle databases in 2 different servers PROD and TEST instances. the two databases are in gr 10 2 in linux servers.
  
  My PROD database contains about 300 GB of data and is dedicated for production area.
  My Test database is dedicated to Spanish test for PROD database. (small server in terms of space and RAM comparing to PROD db)
  I would like to synchronize every week TEST db with PROD db with only 2% of the data and all the structures
  Could someone tell me, if you use a datapump export I can import only 2% of the amount of data and the structures ot theere is another way to do it?
  Thank you very much
  
  best regards,
  W

  I'm not really sure what you're talking about. There is no option, expdp and impdp x % of the data, is that? And if Oracle can sovle repositories inetegrity (PK, FK), it cannot be assumed which tables are lookup table (to be entirely exported) and can not assume the logical data integrity.

• How do a link led between two forms that independently of moving

  Hi all

  I am looking for many tutorials how to create something like this:

  http://turbulence.org/works/MyPocket/graph/

  (the video is on the right)

  But could not.

  I have for each shape, I do 2 circles (move separately) and between them, making a shape that works as a link, related on each circle on the sides... is it clear? I need the link to 'stretch' and follow the two circles...

  Do you know if there is a way?

  Thanks in advance

  m.

  Use something like this technique from an old blog post, I did years ago:

  I created a layer named string and a layer called Kite. I drew a mask on the layer of string that forms a gentle arc, added the effect of outline with a width of 3 pixels and paint on Transparent selected. The race goes from the left edge to the right edge of the layer in the chain, and it is important. The string layer is slightly narrower than the model to make it easy to work with. The last step with the layer of string is to move the anchor point to the left most vertice point of the mask at exactly a value X 0. It is also important. The two layers are converted to 3D.

  The Kite layer is simply a square solid with a mask in the shape of the kite and the anchor point where is used the string.

  The following terms are added to the string layer:
  String scale:

  point1 = position;
point2 = thisComp.layer("Kite").position;
L = length(point1, point2);
w = thisLayer.width;
r = L/w*100;

  [r, value[1], value [2]]

  String Orientation:

  t = thisComp.layer("Kite");
l = thisComp.layer("String");

  fromPoint = l.position
atPoint = t.position
lookAt(fromPoint, atPoint)

  If you look closely the language, you'll see that I'm calculating the distance between the anchor and then dividing the difference in the width of the layer and multiplying that number by 100 to arrive at a scale factor to make the string layer is always the same length as the distance between the end of the chain and the kite. The part of the Orientation of the expression simply indicates the string to the wing. There is a problem which must be overome. The string layer is perpendicular to the wing and this part is important, the rotation must be changed to-90 to get things to normal. This isn't another expression, it's just a value that you put in.

  The kite layer also needs an expression to point the wing at the end of the string. The expression of the orientation of the kite is basically the same as the string Orientation expression with definitions for the to and the reverse point. It looks like this:
  Kite Orientation:

  t = thisComp.layer("String");
l = thisComp.layer("String");

  fromPoint = t.toWorld(position);
atPoint = l.toWorld(thisComp.layer("String").anchorPoint);
lookAt(fromPoint, atPoint)

  Now the kite can be moved and the string will follow.

  Here's the project file

  Here is a movie.

• Help the records removed from synchronization between two databases

  Hi guys,.

  I am new SOA and process management, so please bear with me.

  I created composite simple synchronization using two Dbadapters. A DbAdapter to share records and others to insert and update data in another database. My question is how can I detect deletions and delete records in another database.

  One of my friends told me to use DB triggers, but I want to do with SOA application using preferably the BPEL components.

  Any help would be useful.
  

  Thank you
  

  You can query the database if records are soft deletion, survey in the soft deleted records and then update the database target.

  If these are harsh destruction then the only thing I can think is: -.

  Source database: select * from source

  Target database: delete all records

  Target database: insert the records from the source.

  Other triggers would be best.

• Two databases on a single server - CPU allocation

  Is there a way of CPU resources between two databases in the same way that the resource groups can allocate resources within each database? Let's say split 60-40 between databases cpu?

  The answer is no. I think, it seems that you encounter a performance problem, and you try to solve it using process priorities. Am I wrong? Or I'm going to upgrade my crystal ball?

  If you were never able to do such thing, the first thing that comes to mind,... what you define as "the database" here, you do not have something you can touch and say "it's the database", the concept of database is a logical, not a physical concept, it is composed of memory, processes and files , and the main activity has to do with e/s where most of the time the problem of startup performance. even if you were able to abstract the logical concept of the DB in a single physical component, allocating CPU him would not be enough to solve performance problems.

  I strongly suggest to detail why you want to do this assignment and then we can discuss alternatives from there on.

• 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

• 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

  Make sure you have all the TNS entered in the TNSNames.ora file in the new environment. To match the details of the database data in the connection to TNS entries pool if they point to the correct database.

  I hope that the structure of RPD is same in both environments IE users, groups are same.

• 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.

• "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.
