Hi Folks, @PaiChung @CarlesColl @Constantine  I have 500 Things to fetch properties from.And I have already tried fetching the Things first and then query for required properties only. But it still takes lot of time to execute.   Is there any other way to fetch larger set of data from Things in a least possible time.   Note: Already tried below workaround but no luck.          var ThingsList = ThingTemplates["Template"].GetImplementingThings();                 var params = {                     types: "STRING" ,                     t: thingsList ,                     columns: "MachineNumber",                     expressions: "Things[name].MachineNumber"        &

Hi, I'm trying to get the file from remote TW server's SystemRepository to local file system, after calling all necessary C SDK v2.2.1 API functions: twApi_Initialize(hostname, port, (char*)TW_URI, myPasswordCallback, NULL, MESSAGE_CHUNK_SIZE, MESSAGE_CHUNK_SIZE, (char)TRUE); twApi_SetSelfSignedOk();twApi_DisableCertValidation(); twApi_BindThing(thingName); twcfg.file_xfer_staging_dir= (char*) "/home/davmel/stagingdir"; twFileManager_Create(); twFileManager_AddVirtualDir(thingName, (char*) "incoming", (char*) "/home/davmel/stagingdir/transfer/incoming");twApi_Connect(CONNECT_TIMEOUT, twcfg.connect_retries);   Here all above calls return 0 error code. But when I try here to get the remote file, I'm getting 1114 TW_GATEWAY_TIMEOUT error code.    err = twFileManager_GetFile(systemRepo, "outgoing", sourceFile, thingName, "/incoming", targetFile, 40000, FALSE, &tid1);   The remote thing thingName is created as thing based on RemoteThingWithFileTransfer template.

Hi,   We are working with the trial version of ThingWorx and we are taking some performance bench marks for data read/write to Things. For read we are using QueryPropertyHistory service via ConnectedThingClient in java sdk. For write we are using WritePropertiesVTQ api on ConnectedThingClient.  These reading will be affected by the hosted server's location and the deployment structure of the server (cloud/on premise). So can anyone please help us with the information about where the hosted server is located?    Regards, Vaishnavee

Hi, I have a device connected over Modbus TCP/IP channel and logs data correctly. OPC quick client shows correct value. Once i turned off device, data quality is bad because of no communication. when i restart a device, there is no good data seen in OPC quick client. I have to delete channel and device and re-add it again along with tags. Once i will do it, it will start showing good quality data. Everytime i can not do that when i am using this during live production. Can you please suggest where i have to focus for this?Sometimes it has been observed in log that it shows error code 10061. 'Socket Error Occured connecting'.  Error=10061. 'No connection could be made because the target machine actively refused it'.

Hi  We are trying to update data table during run time and we are encountering the following exception some times. We observed like after 3 or 4 continuous operations we are getting this error.   java.util.concurrent.ExecutionException: java.lang.RuntimeException: com.thingworx.common.exceptions.DataAccessException: [1,018] Data store unknown error: [Error occurred while accessing the data provider.]   The following is the data table structure snippet, we have 2 string columns as primary key and the max number of records are less than 50 in this data table.    The following is the service we are using to update the data table. var params = {tags : tags,source : me.name,values : values,location : location}; // AddOrUpdateDataTableEntry(tags:TAGS, source:STRING("me.name"), values:INFOTABLE(IIOT_EN_DT_ResponsiblePerson), location:LOCATION):STRINGvar id = Things["IIOT_EN_DT_ResponsiblePerson"].AddOrUpdateDataTableEntry(params);   It is a show stopper for us n

I have a drop down widget which is dependent on another drop down. So when I select the first drop down the second drop down get's populated respectively.My requirement is that when my second drop down is populated if the list has only one value(i.e 1 row) it needs to get auto selected, but if it has more than 1 value in the list I don't want the auto select option.So I cannot use the "Auto select first row" property as it will not satisfy in case I have a list with more than 1 value.Is there a way to configure my drop down such that it get's auto populated only if 1 value is present in the list.

Suppose, if you have uninstalled ThingWorx Flow successfully with appropriate steps. And, tried re-installing which is failing with below error in the flow installation logs,      " FATAL: SystemCallError: windows_service[RabbitMQ] (orchestration::rabbitmq line 120) had an error: SystemCallError: The specified service does not exist as an installed service. - OpenService: The specified service does not exist as an installed service."     This is due to the registry problem. To resolve this, need to delete the registry key. Following steps are need to be performed:    Go to Start-> Search and Run 'regedit' as an Administrator Navigate to 'Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Ericsson' Delete Ericsson key and its sub key Restart your machine Install ThingWorx Flow again and it will be successful.   Here is the article link on this subject: https://www.ptc.com/en/support/article/CS328600     Thanks, Vibhuti Angne

I have tried creating variable in both the mashup & assign the variable  from DB service to navigation panel/as well to local Mashup variables property. But when double click- new mashup is coming but not able to passing values. 2. I tried with creating one thing service and assign the values to property- but that is also not working. Can anyone please tell me - which event to fire to pass the variable to other mashup as well how to navigate.   Thanks in advance! ~PC

Hi everybody,   I am not able to set the Cache Method of a Remote Thing Template created via services. I am using the AddPropertyDefinition function. Since there is no option to set cacheTime directly, I included it in the remoteBindingAspects option, but I am not sure the syntax is correct or whether I can even do that or not:   var remoteAspects={ cacheTime:-1, }; var params = { // defaultValue: undefined /* STRING */, remoteBindingAspects: remoteAspects /* JSON */, // description: undefined /* STRING */, // readOnly: undefined /* BOOLEAN */, type: me.PressProps.rows[i].DataType /* BASETYPENAME */, remote: true /* BOOLEAN */, // remotePropertyName: undefined /* STRING */, // timeout: undefined /* INTEGER */, // pushType: undefined /* STRING */, // dataChangeThreshold: undefined /* NUMBER */, // logged: undefined /* BOOLEAN */, name: me.PressProps.rows[i].PropertyName /* STRING */, // pushThreshold: undefined /* NUMBER */, dataChangeType: "ALWAYS" /* STRING */, //

I created a PMML model with R and want to import it into Thingworx. In the Analytics Manager I created an Analysis model but I can't enable it because it's not ready for testing. I do I make it ready for testing?

Hi, Is there a particular guide or series of steps that we have to follow while upgrading from Thingworx 8.4.5 to 8.4.11. I mean is there any DB upgrade script or something else, or I can just replace the WAR file. I am using MSSQL as persistence provider. I know that when upgrading from Thingworx 8.4 to 8.5 we have to follow certain steps, which includes running DB update scripts and some backup, but I was not able to find any such information when I want to upgrade from 8.4.5 to 8.4.11. Thanks in advance Aditya Mittal

Is there a way to check the parent user group of a user group?  Is there such a service?

Hi    I wanted to know if there is way I can get the data provided in different widgets in a mashup as a group or like an infotable into my service. If I make this a bit clear, let's say I have a scenario where I have a mashup where the user will be providing details of the item they have purchased. I am having 2 text boxes (name of the item and price) and I also have a drop box to get the category the item belongs to. If the user have brought 2 items then there will be total of 4 text boxes and 2 drop boxes. If I am giving the values from these widgets directly to my service then I will have to limit on the number of items the user is buying but I need this to be dynamic.For this purpose I gave a grid where I had written a service to make blank or empty rows depending on the number of items (like if there are 2 items then the grid will have 2 empty rows). This grid was an editable grid too. But the issue then was that I was not able to give a drop box inside a grid. I also t
