• Missing for DBAdapter cluster Weblogic Congfiguration outbound connection Pool entry

  Hello

  When I created an entry for outbound connection pool in DBAdapter weblogic console in a clustered (1-Admin server and servers managed by 2) environment and updated adapter DB, I have identified only input connection is updated in that plan a managed server and other server managed, it is not updated. For this reason, we are unable to access the data sources for some requests for the application.

  As a work-around if we plan. XML file to another server managed manually with update and DB adapter connection entry, we are able to find the entrance of connection for managed servers.

  Outside work around there at - it another solution to this problem so that I can add a connection adapter DB Console entry that will update the two plan files.

  Thank you and best regards,

  Can I propose to maintain the file plan of shared drive accessible from all nodes in the server, this will reduce the manual work.

• the connection of WebLogic connection pool timeout issue too soon

  We are having a problem with the connection to weblogic pool. Our web application is based on the Spring Framework, deploy to Weblogic using the data source to connect to Oracle. We use a duration of 1 min and max setting of connection pool 15 on weblogic. But the problem that we face is that the pool does not manage any connection as a pool. Each request makes a new connection to the Oracle server and right closed within a few seconds of connection. The number of new connections could be easily up to more than 100 within 10 minutes.
  
  Is there a timeout parameter to check the living connection? Could someone please share your thoughts how to solve the problem? Your help is really appreciated.

• 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.

• Time of excessive latency of connection... Adobe Air supports on mobile connection pooling?

  Hello

  I'm developing a mobile application that loads the thumbnail images to a remote server. During testing on the Android platform, however, I discovered that the images are very long to load. By monitoring the server logs, I determined that poor performance is caused by the absence of connection pooling, which means that each request creates a new connection. Running the sample code below on a mobile device produces 20 applications and 20 attempts to connect. By comparison, the same web application or desktop creates 2 connections and reuses connections for the following applications. Important overhead and latency associated with generating new connections has a significant impact on performance, with 20 thumbnails taking about 4-5 seconds to load on mobile compared to 0.5-1 second on a desk.

  I've included a sample application below the emphasis placed on the performance issue. The image itself is very small (290 bytes), to focus the issue on the latency of the connection. I confirmed this behavior on many Android devices running 4.1, 4.0 and 2.3. I also tried using the charger c. URLLoader v. URLStream and v. sequential loading with no change in the behavior of simultaneous connection. Trying to set up the connection to 'keep-alive' in the URLRequest has also no effect.

  package

  {

  import flash.display.Loader;

  import flash.display.Sprite;

  import flash.display.StageAlign;

  import flash.display.StageScaleMode;

  import flash.events.Event;

  import flash.net.URLRequest;

  import flash.utils.getTimer;

  SerializableAttribute public class Main extends Sprite

  {

  private var _count:int = 0;

  public void Main()

  {

  Super();

  internship. Align = StageAlign.TOP_LEFT;

  stage.scaleMode = StageScaleMode.NO_SCALE;

  trace ("Start time" + getTimer() + "ms");

  var loader: Loader;

  var url: String = " " http://fbcdn-profile-a.akamaihd.NET/static-AK/rsrc.php/v2/yo/r/UlIqmHJn-SK.gif ";  290 bytes

  for (var i: int = 0; i < 20; i ++) {}

  loader = new this.addChild (Loader()) as a charger.

  loader.contentLoaderInfo.addEventListener (Event.COMPLETE, complete);

  Loader.Load (new URLRequest (url));

  }

  }

  private void complete(event:Event):void

  {

  _Count ++

  trace ("Completed" + _count + 'to' + getTimer() + "ms");

  }

  }

  }

  So, I have a few questions:

  (1) is there something I can do to allow the reuse of connection?

  (2) is it an inherent limitation with Adobe Air for mobile?

  (3) is that someone can confirm if this limitation exists on other mobile platforms (iOS or Blackberry)?

  Any help you can provide would be greatly appreciated. I really hope that this isn't a fundamental limitation of Adobe Air because it weakens my application to feel very slow.

  Thank you

• Switch Connectivity

  Hey Cisco experts!

  I have a small question, I'm sure you can answer for me. I have installation of the Israeli army for the clients that I questioned how they are physically connected. Connection to the MDF is ok because they use their ports of 10 GB on fiber optics. The question I have is if there are multiple switches in the Israeli army should they be connected to each other using their 10 GB ports from A to B and C and then also to connecting A to C on switch ports? I think it's can cause a loop but wanted expert advice.

  Thank you

  Hello

  Yes, when you have multiple MDF switches, connect together to provide redundancy of the network.  Of course if you connect to layer-2 switches together, you must run stp or use some other technologies like stack to make it look all MDF has a switch.  There are also VSS for the 6500 that offer the same advantages as the stacking on the 3750 series.  In this way, your don't have to use STP.

• 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.

• 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.

• NLS parameters in a connection pool environment

  I have limited experience of localization/globalization and I am building an application, using Oracle APEX 4.2/Oracle 11 g db, which takes care of several users of different nationalities.  I have a specific question, but first... can anyone recommend good books, blogs and websites to learn more about best practices for the many things you need to think in this area?

  Second, my precise question is... Since my application will use a connection pool, how it works as far as setting the NLS parameters for a given client session?  In the typical client/server architecture that I know that you would simply change the NLS parameter when the user connects, and this change would govern just the session of this user database.  It's a different approach when we are in an environment of connection pool?  If this is not the case, how Oracle now manages the parameters of the client session this session of customer may engage in more than one session of db in its lifetime?

• vRO (vCO) HTTP-REST Workflow - connection pool closing

  Hi all - I've recently upgraded to vRealize Automation 6.2 and works collaboratively with vRealize Orchestrator to create workflows.  I created HTTP and REST workflows for request/release an IP address from our system IPAM (VitalQIP) and it seems to be failing with the description / the following exception:

• API - POST - REST VCO connection pool closing

  Hello

  I'm working on an automation scenario where I need a VCO A workflow to start another workflow VCO B using the VCO REST Plugin (1.0.2) on VCO 5.1.1.

  I did it with success while creating a multitude of REST and surgery REMAINS by using the appropriate workflow. However, my approach is a lot of static and I need to create REST operations on the fly. I have had a look at workflows Plugin and try to do the same thing in my workflow.

  However I am stuck with the error 'Connection Pool close' when you try to run the POST request.

  My approach is to store the host REMAINS as a static attribute with VCO configuration object and retrieve it from there. I can run GET operations without any problem with the owner, i.e.

  
  restRequest = restHost.createRequest (restType, restUrl, restContent);

  restResponse = restRequest.execute ();

  My problem is actually running a POST operation. I prepared the content in XML format, which is

  " <-xmlns = execution context" http://www.VMware.com/VCO "> "
  < Parameters >

  < name parameter = "param1" type = "string" >

  < string > 1 < / string >

  < / parameter >

  < name parameter = "param2" type = "string" >

  < string > value2 < / string >

  < / parameter >

  < / Parameter >

  < / execution context >

  and use the content type "application/xml". Earlier in my code, I run a query GET to retrieve my ID for workflow target to create a Url like this:

  flow of work/98c3b8ee-9569-4940-acc1-b8fbc2e64649 / executions.

  This is code that I use to make the POST while creating an operation of REST when needed and delete it later.

  
  var restOperation = new RESTOperation (System.nextUUID ());

  restOperation.method = restType;

  restOperation.urlTemplate = restUrl;

  restOperation.defaultContentType = restContentType;

  restHost.addOperation (restOperation);

  RESTHostManager.updateHost (restHost);

  inputParameters var = [];

  var restRequest = restOperation.createRequest (inputParameters, restContent);

  restRequest.contentType = restContentType;

  var restResponse = restRequest.execute ();

  restHost.removeOperation (restOperation.id);

  RESTHostManager.updateHost (restHost);

  My code does not work when calling for the lifting of restRequest.execute: ' InternalError: connection pool arrested "." If anyone else has tried a similar scenario or has any idea what I may be missing?

  Thank you

  Bernd

  Thanks chap - update the objects did the trick.

  In my case, that initially caused the problem travel of COULD happen. Of course store the restHost object in the configuration of VCO leads to an out-of-date version at run time. I'm now store the ID of restHost only. Then, copy the following code works:

  var restHostId is System.getModule("my.library").myGetConfigAttr ("Folder", "VCO", "restHostId");.

  var restHost = RESTHostManager.getHost (restHostId);

  If (restType == 'GET') {}
  try {}
  restRequest = restHost.createRequest (restType, restUrl, restContent);
  restResponse = restRequest.execute ();
  }
  catch (exp) {throw ("request REST to run: cannot run '" + restType + "' '" + restUrl + "' request-reason = '" + exp + "'") ;}}
  }
  else {}
  try {}
  var restOperation = new RESTOperation (System.nextUUID ());
  restOperation.method = restType;
  restOperation.urlTemplate = restUrl;
  restOperation.defaultContentType = restContentType;
   
  restHost.addOperation (restOperation);
  RESTHostManager.updateHost (restHost);
   
  restHost = RESTHostManager.getHost (restHost.id);
  restOperation = restHost.getOperation (restOperation.id);

  inputParameters var = [];
  var restRequest = restOperation.createRequest (inputParameters, restContent);
  restRequest.contentType = restContentType;

  var restResponse = restRequest.execute ();

  restHost.removeOperation (restOperation.id);
  RESTHostManager.updateHost (restHost);
  }
  catch (exp) {throw ("request REST to run: cannot run '" + restType + "' '" + restUrl + "' request-reason = '" + exp + "'") ;}}

• SQL Plugin - connection pool &amp; retries

  People-

  We use vCO workflows which a lot of CRUD operations on the database. In light of these are long-running workflows with a decent amount of load, we want to make sure that this solution we have in place is efficient and reliable. To this end:

  1. we want to ensure that we are able to reuse the database connections - y at - it the notion of Pools of connections or equivalent.

  2 How about reconnecting to the db when it falls down? Is that something it will take the code in the workflow through say managers of exceptions etc..

  I'm sure that others have encountered similar problems - would appreciate all comments that you may have.

  See you soon.

  Hello

  Unfortunately does not support the plugin SQL connection pooling. We have never considered it. We will discuss it and may include in the next version of the plugin update.

  Regarding your second question - we don't keep connection open for a long time and call evry DB is atomic. When you run workflows CRUD a new conncetion is created, the corresponding SQL query is executed / clerk and the connection is closed. If there is a problem, as the disconnection of the server Oracle, the right way to ensure that your operation has passed is to write a custom error handling by using the Scripting of the Orchestrator features. In pseudo-code:

  var hasPassed = false;
  for (i = 0; i< maxretries="" -1="" &&="" !haspassed="" ;="" i++)="">

  hasPassed = false;

  try {}

  Execute the statement using the JDBC API exposed or by using CRUD actions

  hasPassed = true;

  } catch (error) {}

  Save the problem

  }

  }

  Hope this helps you. Any additional comments will be great.

  Best regards
