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

Similar Questions

• 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 + "'") ;}}
  }

• Migration http - rest in 5.5.2 workflows 6.0.2 does not not for me.

  Hey there.  I try to get my workflow migrated on to 6.x and the work I've done with the http-rest plugin is a failure.  Once I have import the package, I see the resource in the HTTP-REST folder.  If I run the workflow to reload the configuration of the plugin I don't see the host appears. I checked that I can create a new host, that seems not be recognizing any host.  I also noticed that it creates the new host in a different folder of REST\Configuration.  If I restart the service orchestrator, run the "reload the plugin configuration" the workflow, I get an error that says "The valid String is empty.  If I look at the contents of the REST\Configuration file, I see a partially created resource content reads:

  <? XML version = "1.0" encoding = "UTF-8" standalone = "yes"? >

  < pluginVersion endpoint = "1.0.8" >

  < properties / >

  < / endpoint >

  As he began to process the file imported and choked on something?  Anyone has an idea on what could happen?  I am struck a major obstacle here.

  The two vRO servers are windows installs.  Source is 5.5.2 and plugin version 1.0.3.  Destination is 6.0.2 and plugin is 1.0.8.

  Paul.

  After more digging with a pick, we found this error as org.bouncycastle.crypto.InvalidCipherTextException well: block corrupted buffer.  This is of course related to something that need encryption.  The only thing in the resource element that had any kind of encryption was around the password for the endpoint that has been configured to use a shared session.  I changed the configuration to use a session per user, sync since the changes, refreshed/reloaded the plugin remains.  Endpoint seems to get processed without errors.  Updated the host remains to use a shared session.  Completed without error.  Seems to work fine now.  I hope this will get fixed as he sucked toward the top of many hours of my time.  It seems that there are similar errors with the PowerShell plugin and I'd be curious to see if it's the same type of problem with a piece of this configuration do not decrypt after syncing account to another server.

• 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.

• vRealize Automation API and HTTP-REST

  Hello

  Management of the booking does not include the current version of the plugin vcac. I guess that because that is a new feature of vRA API.

  Can how I add vRA API as host HTTP-REST in Orchestrator? The problem is the permission based on tokens. You must post a json on/identity/api to get the token and then use this value in an http header. I don't know how to do this.

  First a new version of the plugin vcac soon with the feature of booking?

  Thank you very much

  D.

  You can always add a crowd of VRA rest with no authenticaction, but you will still need to obtain an authentication of the symbolic holder and who spend using an authorization header. I would recommend a disconnection of your output chip once you are done so that you do not leave chips remaining. Once you have a workflow to get a token, you can then start to take advantage of the API normally... 6.2 has a new service of booking via the api REST of COFFEE, or you can use the CRUD operations and linqpad to create and edit reservations based on the plugin infrastructure, vRA.

  Take a look at this post to get a token

  grantorchard.comvCAC 6.1 API - authentication | grantorchard.com

  You can watch this post to add or pass in the additional headers to the rest of the API:

  Relevant documentation for JDBC 9i drivers here is http://download.oracle.com/docs/cd/B10501_01/java.920/a96654/connpoca.htm#1056354.

  In the world of JDBC 9i driver, there was a distinction between a connection pool (consolidated connection) and a cache of connections.

  A connection pool is trying to eliminate overhead consumption and resources of connection / disconnection from the database. If the connection is going to be only reused so no reason to close the connection, just open it again.

  What a performance gain were you looking for? Only, you would see a performance gain if your application was constantly opening and closing of connections, demanding that all resources for Setup and take down communications database. When the connection is established there is no difference in the performance of the execution of SQL.

  You can see with

  import java.sql.Connection;
  import java.sql.ResultSet;
  import java.sql.SQLException;
  
  import oracle.jdbc.pool.OracleConnectionPoolDataSource;
  import oracle.jdbc.pool.OracleDataSource;
  import oracle.jdbc.pool.OraclePooledConnection;
  
  public class TestConnectionCache {
  
    public static void exec(Connection conn) throws SQLException {
      ResultSet rs = conn.prepareStatement("select sys_context('USERENV','SESSIONID') from dual").executeQuery();
      rs.next();
      System.out.println("Session id: " + rs.getInt(1));
      conn.close();
    }
  
    public static void main(String[] args) throws SQLException {
  
      OracleDataSource ods = new OracleConnectionPoolDataSource();
      ods.setUser("...");
      ods.setPassword("...");
  
      // Construct the jdbc url.
      String host     = "...";
      String port     = "...";
      String instance = "...";
  
      String url =
        "jdbc:oracle:thin:@//" + host + ":" + port + "/" + instance
        ;
      ods.setURL(url);
  
      // No connection re-use.
      exec(ods.getConnection());
      exec(ods.getConnection());
  
      // Connection re-use. (Connection pooling)
      OraclePooledConnection opc = (OraclePooledConnection)((OracleConnectionPoolDataSource)ods).getPooledConnection();
      exec(opc.getConnection());
      exec(opc.getConnection());
    }
  }
  

  Product output similar to:

  Session id: 4110149
  Session id: 4110150
  Session id: 4110151
  Session id: 4110151
  

  Note: when the pooliing connection is used, the session of database id is the same. Call close() has not closed the physical connection.

  A cache of connections is a layer on top of pooled connections that manages the creation and destruction of the connections. There usually limits this link how much should be open and the maximum number of connections to allow. Then the cache is queried for a connection, it can return the one that is not in use or perhaps create a new.

  Later versions of the JDBC driver will greatly simplify managing your connections and here is the note of documentation:

  Note:
  The previous cache architecture, based on OracleConnectionCache and OracleConnectionCacheImpl, is discouraged. Oracle recommends that you take advantage of the new architecture, which is more powerful and offers better performance.

  Any reason you're not not using a newer driver?

• 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.

• HTTP-REST 2.0 - accept application/json

  It seems that the "request.setHeader("Accept","application/json")" does not work with HTTP-REST plugin 2.0.

  I configured a host BASED HTTP pointing to NSX and works so as to gain an advantage by using the URL "{/ api/4.0/edges/{edgeId}. In the 'operation of appeal' workflow, I add the following line:

  request.setHeader ("Accept", "application/json")

  It works perfectly find on a vRealize Orchestrator 6.0.3 with HTTP-REST plugin version 1.0.9 and returns a JSON response. But with vRealize Orchestrator 7.0.0 by using HTTP-REST plugin 2.0.0 version returns an XML response.

  How can I get the JSON response with the 2.0.0 version?

  Thank you very much!

  D.

  I found the answer myself.

  Incredibly, with this release, this command does not work:

  request.setHeader ("Accept", "application/json")

  
  

  Instead, I need to use only in small print:

  request.setHeader ("accept", "application/json")

  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?

  You can set the runtime: http://docs.oracle.com/cd/E16655_01/appdev.121/e17961/global_primary_lang.htm#HTMDB14002

• 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,

  Vincent

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

• HTTP-REST plugin - how to PUT binary content?

  Hello.

  Does anyone know what is the right way to use the HTTP methods - REST Plugin to download binary content on the server using the method PUT?

  I have no problem to download a text file (even with the size of a few megabytes), but even with a small binary file (30-40 KB) the server returns HTTP 500 error.

  Changing the value of the contentType to 'application/octet-stream' field does not help.

  Thank you.

  Based on a recent application, one of my colleagues has provided examples of code that downloads a file by using the HTTP-REST plug-in...

  file = name of the input variable. vCO object type is MimeAttachment

  restOperation = name of the input variable. vCO object type's REST: RESTOperation

  Before the code specified at that location, you need to establish your inputParametersValues are for the query:

  // Set the request contentType to the file's mime type
  var request = restOperation.createRequest(inParametersValues, file.content);
  request.contentType = file.mimeType;
  System.log("Request: "+request);
  System.log("Request URL: "+request.fullUrl);
  
  // Set whatever additional headers you may need here:
  // request.setHeader("headerName"," headerValue");
  
  // Execute the request:
  var response = request.execute();
  
  System.log("Response: "+response);
  // prepare an output:
  var statusCodeAttribute = response.statusCode;
  System.log("Status code: "+statusCodeAttribute);
  

  I hope that's enough to help out you...

• 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

  Import the table with ODBC and change the interface call OCI connection pool.

• 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.

• 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

  Both are on the exit compilation, which should take all of the variability. So, Yes, it is as if the Runtime AIR 3.4 lost the pool of connections, but ONLY for Android.
