• OBIEE 11 g RPD migration - how to automate the Connection Pool passwords changes in environments

  Hello gurus

  We have a situation in our client, where I am responsible for automating RPD Migrations in environments. In our current scenarios, (SID database) data source names and user names (schema name) are same in environments. The current process deploy us the RPD by EM then SPR online by using the administration tool and manually open update passwords in each connection pool (we have 9 pools of connections). There has been a lot of problems with this approach you can imagine (especial when do things the manual way).

  Can you please provide a better approach to automate this process in order to avoid human error.

  Thank you very much.

• Pool table of event in the connection pool of 11g OIC for obiee 11g

  Hi all, I tried to use the event pool table using the OIC 11 g connection pool. A deleted event, but cache pool table records did not get purged after 60 minutes interval. Should we do addition together upwards to event pool table when you use oci 11g other that makes it active? It seems that it works only with odbc to connect. http://gerardnico.com/wiki/dat/obiee/event_table thanks, Sushil

• JDeveloper PL/SQL WebService deployment to use the connection pool

  Hello
  
  JDeveloper/OAS 10.1.3.4
  
  We have generated Web Services based on package/procs of PL/SQL by using wizard. When we deploy, it generates a new pool of connections and the connection on the OAS. If change us the Web Service in JDev to use a connection Pool existing and redeployment, it always creates a new connection/connection pool.
  
  Change: oracle - webservices.xml, web.xml, and < ServiceName > base.java files
  
  Anyone know how to get around this without using WebServicesAssembler?
  
  Thank you

  When you deploy the server, don't include any local data sources. In JDeveloper:
  1. choose Tools > Preferences to display the Preferences dialog box.
  2. Select the deployment on the left side.
  3 uncheck data - sources.xml during deployment of default package.
  This can be changed later for other projects if you do not want to deploy the data source.

• Business leader knows the connection/disconnection/display issues

  Our VP of finance was recently provided with a new HP Probook 8770w. It has a docking of 90 watts and an SSD. She complains that when she shut the machine and detaches, then opens again the machine for meetings she can not get display drivers to detect other options to display as you reconnect to an another external monitor or projector. What is the best driver we can provide him and what other steps should take to ensure that it is able to disconnect/dock, sleep and display dynamically and smoothly? I'm the support office for this company engineer. I use HP almost exclusively and it would be useful to have a way to resolve this sort of thing (as I've seen before).

  Thank you.

• WebLogic datasource County connection active more than the max connection pool

  Hi guys,.
  
  We will observe strange behavior on one of our WebLogic instances. A data source is set up with an initial and maximum of 50 capacity, and yet the source of data analysis, we see a number of active connections more of 50 years. In fact, it continues to rise up to 800, after which the database stops to deny connections (obviously).
  
  Why the maximum capacity of the connection pool is not respected?
  
  We lack WebLogic 10.3.5 and the connection pool is connected to an Oracle database using the driver oracle.jdbc.OracleDriver.
  
  Thank you!

  Yes, wire-PIN is documented to override your init-max because it takes
  a connection by running WebLogic threads. If your application also generates its own thread
  who get to pool connections, you have 800 (ugly) son, with a connection.
  This would indicate use suboptimal pool too, which is better to use in getting a connection, using
  and close the ASP, all in a single method call, if the connections are not kept for long periods
  by any thread.

• Connection pool with the OAS and the optimal value of min/max

  Hello world
  
  
  I have ", works with admin app to implement under oracle application server connection pool. The current value is min = 0, max = unlimited which I think means not implemented connection pool.
  
  Anyway I don't have a lot of information on connection pooling, I searched the forums, but I'm not able to find any useful information.
  
  
  My Manager would like to know what is the optimal value for min/max for the database, is there a specific formula or a tool that can help me on this issue?
  
  
  Thanks in advance.

  Hello

  It's a specific formula or a tool that can help me on this issue?

  The value that you specify for the number of connections and connections Min depends on a combination of factors, including the size and configuration of your database server and the type of the SQL operations that
  your application runs.

  For connection pooling,.
  First, check what is the value of 'process' located on the end of DB (for your current value, check v$ resource_limit at the end of db)...
  for example if the process is set to "1000", you cannot set the maximum value of the connection pool to the end server application above 1000 it will crash your database.

  now on the server side Application.
  As a best practice, set the maximum number of open connections and Minimum of connections open to the same value.

  For more details on connection pool and its settings.
  Check "Setting Up Data Sources - Performance Issues" of the link pdf below

• After the connection is closed, the oracle session remains unavailable

  Hi all

  using weblogic.jdbc.wrapper.PoolConnection_oracle_jdbc_driver_T4CConnection;

  with weblogic server 12 c I can't release the connection to the data source.

  Even when the web application made the destroy method,

  Oracle sessions are allocated, and every time I reconnect, the number of sessions pushes saturating the connection pool.

  What can I do to properly release resources?

  Thanks in advance

  That's what I see in oracle:

  SID; STATUS; SERVER; PROGRAM

  537; INACTIVE; DEDICATED; JDBC Thin Client

  The source is

  ...

  DataSource ds = (DataSource) context.lookup (jndiname);

  ....

  public connection getConnection() throws SQLException {}

  Connection con = ds.getConnection ();

  return con;

  }

  Private Sub closeConnection (con Connection) throws SQLException {}

  If (con! = null & &! con.isClosed ()) {}

  con. Close;

  con = null;

  }

  }

  ...

  Connection con = getConnection().

  Statement statement = null;

  ResultSet rs = null;

  Statement = getStatement (con);

  Well, everything looks good to me. I'm guessing that the Sessions will continue to be there until the Time Out of Session is reached. Can you please adjust the session timeout down and observe the response?

• connection pool and inefficient query plan

  There is a single query that covers almost 90% of cpu DB.

  Select * from employee e, Department d where e.departement_id = d.department_id

  Us will gather statistics for this table in two, and the issues is resolved.

  This occurs every 2 weeks. That said, the query runs fine for 2 weeks and then we have questions... we will bring together the statistics of these two tables... and things are good for another 2 weeks.

  This query is a proc to store oracle pl - sql, which is called by the JDBC code. I introduced 2 months behind connection pooling, and today, we are facing this problem.

  The query has been accounting for 5 years with no problems.

  Before that I presented the connection pool, the jdbc code created a new connection before calling the store proc.

  Do you think that my connection to the connection pool has introduced this problem.

  The DBA tell me that the query runs a bad plan. Oracle recovers not the more effective plan (and that leads to this high CPU utilization).

  I guess that after 2 weeks Oracle begins to pick up plans that are effective in.

  Do you think all that this question never has nothing to do with my connection pooling code.

  I use Oracle 10 G.

  Hi Mike and ground beach thanks for your response.

  It was just a doubt... that you guys allowed.

• Import metadata connects in online mode, but "view data" says the connection failed

  Hello

  My installation of obiee is on AIX (solutions for linux will be good). I installed successfully obiee. I created a connection odbc with no problems.

  I download and installed the dev admin too i.e. the stand-alone tool.

  Offline, the two 'import metadata' and after the table is imported, 'Examining the data' works without any problem.

  In online mode, I click on 'Import metadata' of the connection pool or file, both instantly connect. Once the table is imported, I select a column and say "Look at the data" and it says that the connection failed. Should the customer Oracle DB installed on the machine as unix? I tried to copy the file tnsnames.ora to my local computer to the OracleBI_1/network/admin directory, restart services and connected in online mode, BUT always "the connection failed".

  Could someone help me with this please? seems to be a known issue.

  Thank you

  YES for the Oracle client.
