• How to create a Pool of connections to two different databases in OBIEE

  Hello

  I have a requirement where few reports coming from databases and a few others to another database. I created two pools of connections and added the frame connection details. But when I created the report I get error as below.

  State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error occurred. [nQSError: 43113] The message returned by OBIS. [nQSError: 17001] Oracle error code: 942, message: ORA-00942: table or view does not exist to the call of the OCIStmtExecute OIC. [nQSError: 17010] Prepare the SQL statement failed. (HY000)

  Now, I would like to see if I can create a pool of connections to two different databases. If so, how that happen.

  Thank you!

  Hi Antonio,.

  Cross database joins are possible, no problem for it. But you do not do so in an object of unique data base in the physical layer using 2 pools of connections connection to the source A and B, then adding objects to A and B children of your unique database.

  You create 2 databases in the physical layer, each with its own connection pool, then you can do your knuckles crossed on the physical schema.

  As a picture is worth a thousand words, take a look:

  

  The physical diagram uses objects of A and B and define the rules of the join between them, it is a cross-database join. But in the physical layer of the database A and B are 2 separate objects each with its own pool of connections.

• During the installation of netflix through my bluray a friend noticed that my router has a secure connection (?), a non secure. How to only two guarantees. I can not even find my router here!

  It's a Linksys e-series router

  Hi Marilurush,

  To provide a proper resolution, I would need more information on your side.

  1. is the issue limited to the installation of Netflix?

  2. don't you make changes to the computer before this problem?

  3. what browser do you use?

  Follow these steps to secure your wireless connection.

  1. connect your router wireless according to the instructions in your user manual.

  2 open your Internet browser and enter the IP address assigned to your router. Leading manufacturers assign IP addresses to their different default routers. For example, Netgear Routers use 192.168.0.1 while Linksys uses 192.168.1.1. Check the manual of the router for more details.

  3. connect to your router by typing the username and password specified in your manual.

  4. set your SSID (Service Set) Identificatier by typing it in the box. Is the name of your wireless network. Make a single sentence; the default SSID is usually the name of the router manufacturer, such as Netgear and Belkin.

  5. set the Security Protocol of your 2.0 - Wi - Fi Protected Access WPA wireless network. This encrypts all data sent over the network and allows access only to users who have the security key. Set your security key as something not easy to guess. A string of random numbers and letters is recommended. Do not forget to save this security key in a safe place, so you can remember when you add a new device to your network, or changing the settings of network security.

• Direct DB request - Connect 2 patterns using 2 pools of connections at the same time?

  Hi all
  
  Will be "Request for Direct database" feature allows to connect to two pools of connections at the same time?
  
  Output report is based on the UNION of two select statements from two schemas, two pools of connections are created to access two schematics
  
  First select statement comes from a single schema and second select statement just forming the other
  
  Select Column1, Column2, Column3 from A, B, C
  UNION
  Select column4, column 5, column6 of X, Y, Z
  
  A, B, C paintings come from the first schema and X, Y, Z come from another
  
  How to get the above out put using "application for Direct database"
  
  Kind regards
  SMA

  It is a very bad idea. If you connect to the same base, then it will be much better to simply synonymous and grants between the schema1, schema2 objects so that you can use a single connection. You query will go much quicker since the BI server do not have to run separate queries to stich together data. If the data are two different databases, it is advisable to do some ETL and group all the data in your Data Warehouse database.

  If you are in a service / filter, it is best to make queries as below in order to create a new (read: extra!) system database connection (and the handling/connection additional error closing you must take care of). Samples are available in the HowToComponents.

  final ResultSet myResultSet = m_workspace.createResultSetSQL( "select * from managedlinks" );
  

  or better yet

  final ResultSet myResultSet = m_workspace.createResultSet( "QManagedLinksTable", null /* no params for this query */ );
  

  and define the outer query in your component.

• Can a DB function used between 2 pools of connections

  Hi all
  We have 2 pools of connections, 1 connected to Oracle DB Data Warehouse. The other connection pool is an Excel spreadsheet, which has projects and scheduling dates. We have modelled in MDB and her servant perfectly. Now, the question is, we have a function in Oracle DB, which works well when I use with any size of Oracle DB DW. But, when I use the same function using the dimension modeled of excel sheet it generates an error. Here, dimension sheet Excel is modeled to inculde model DW.
  
  Error: "A general error has occurred. [nQSError: 42015] Cannot function ship the following expression. »
  
  So my question is "is there no work around to use the same function when using the other connection pool size.
  
  Pointers for this problem is highly appreciated.
  
  Thank you
  Vijay

  Hi Vijay,

  I agree 100% with what Dave. The function you have in Oracle should have access to the values passed in. OBIEE has access to both DIM_DW and DIM_EXCEL, but the Oracle function has no access to DIM_EXCEL. Just to give you a high level understanding of what is happen, here's what OBIEE made to combine the two sets of data in a single report:

  Assume that your report is like so: DIM_DW. COLUMN1, DIM_EXCEL. COLUMN2, FACT_DW. MEASURE1

  To get the data OBIEE sends two separate applications: one against the DW that retrieves DIM_DW. Column1 and FACT_DW. MEASURE1 and another for DIM_EXCEL. COLUMN2.

  Once the two request to return, the OBIEE server joined data sets and then presents them in a report.

  Now, when you call your function (DIM_DW. COLUMN1, DIM_EXCEL. COLUMN2), OBIEE sends the request to just the Oracle DB. But the Oracle DB can not see the Excel data, then it fails because the DIM_EXCEL argument. Column2 is not defined to Oracle DB.

  Here are two methods you could use to make it work:
  (1) configure the Excel file as an external table in the Oracle DB. Then, the function would be aware of the values of column in Excel.
  (2) port the function to the MDB using layer logic the formula Expression. According to what is your function, it is not possible.

  Whatever it is, how you install now, you can't reach your goal. The reason why I recommended that you separate your connection pool Excel in a different database object is because the way you have it setup right now makes it appear like the Oracle DB would be aware of the Excel tables. But that's not true. Keeping them separated to avoid any future confusion.

  Good luck!

• How to create a project that connects in a static library?

  I am trying to create an OpenGL project that depends on a static library which I create in the same workspace in the NDK.  I created two projects (static library and OpenGL app) connects them in the NDK and tried, but I must be missing something because my OpenGL project is not able to see the functions in my static library, even if it is able to find my static library?

  Is there documentation describing step by step how to create two projects and how to relate?

  I found a similar post on the forums and I have solved my problem.

  I used project > add library > library of the project in the workspace but something is broken with this command, because it did not work.

  If you use project > add library > external library, then everything works fine.

• How to have two signatures on a document

  Does anyone know how to have two separate signatories sign the document you send for signature?  Do you need to have two email addresses to allow two different signatories?  What happens if the signatories share the same email address.

  Hello

  Yes, I'm sure you must have separate emails, because it is used to route the document.

  I've tried a few, but have always used different addresses.

  You can specify where the different signatories will sign and what information they must provide (initials, title company, etc.) using designated codes. I hope that you have the guide for this, quite powerful and flexible stuff!

  There are two types of questions, the only choice of response and multi choice answers.
  
  My question is less than

  create table question_master

• How user by VM (XP) can connect at the same time?

  Hello guys,.

  We test VMware View 4 and so far work fine, but I have a question? How many user by VM can connect at the same time? I test with 2 VM (XP) in the pool, but I want to use more than 2 users, but when I try to login doesn't say "no resources available", what that means is that a single user by VM? Us who is running Terminal Server and try to find alternatives.

  Thank you

  It's the same as with a XP machine. 1 single user can connect at the same time.

• How to design and develop?

  How to design and develop?

  I know that it depends on many things such as knowledge, preference, purpose, resources, etc... but I'm curious how different developers (level of expertise) actually prefer or implement their Web sites. I decided to make this post after two rounds of various forums about 1. Templates and PHP, and 2. Development of the back-end.

  1. How do you generally approach a project?-wired, Freehand (because it is), model PSD, etc. - think - you have a specific 'methodology' or procedure?

  2. What are the 2-3 of your main resources / sites / apps etc you are using (and what for?)

  More precisely: what you use (and how) to get a Web site? (I know once again that depends on a variety of things, but in general..) * also if you want to comment on your expertise or maybe useful level.

  Would you rather (benefits / drawbacks of :)) What advice would you give to the topic below?

  • Built your own Script HTML/CSS/base site you have mostly (if not completely). (More control and original, but more difficult / tedious for beginners)
  • HTML Temlplate (change the HTML and CSS code) - type of not setting (quick and easy, but generally poor quality, obsolete?)- but some may servde as a good starting point.
  • WordPress (and others such as Drupal, Joomla) (pretty quick and easy access to wring a quality WP Theme with possibility for a large number of features - search, databases, forms, etc. (otherwise could have trouble with features without good knowledge og PHP and MYSQL, maybe others?) - but the kind of "bypass" real HTML design?)
  • Types of frames such as Foundation, Bootstrap, skeleton
  • A combination or hybrid methods? - or any other method, I forgot?

  Thank you very much for any idea that you can offer, hopeully, this will lead to a lively discussion. -.

  Not quite.   Don't forget there are client-side and server-side apps applications.

  AJAX is client, which means that the browser does all the heavy lifting.  If the end user has JavaScript disabled, nothing happens.

  PHP MySql & are server-side.  It doesn't matter what browser settings has the end user.  The bulk of the work is done by the web server.

  XML is NOT a database on the server side.  It is just a file text used by the browser.  Useful for storage of light data, but certainly not to a large scale CMS or blog for example.

  Apache is an application web server that is commonly found on Linux servers.  It has nothing to do with AJAX.

  for example: change processes control system = 200 scope = spfile;

  >

  I have more clarification on the difference of connections and Sessions.

  Connection means a user process is successfully connected to the listener to have a session on the database running instance. (listener who listen s new connection requests)
  Establish sessions: means, a (dedicated) server process began to serve a user process. It is done when the credentials of the user authenticated successfully. Now, from process-user shall communicate to the server process directly.

  hope that helps.
