How to measure the task instance size

I am trying to understand how to measure the custom task instnace size that was occupied in the cache repository. Is there a way to obtain the size (in KB s ) in lighthouse 4.1 +sp5. Please help.

Hi, Luiz!
In order to estimate the instance size, you will have to sum up all the instance variables size.
From the practical prospective it may be difficult to use the algorithm in cases when your instance variables are not simple types.
For already existing instances, you can look the instance size in the database:
An instance is just a java object, that is serialized as a byte[] and stored in the engine database, PPROCINSTANCE table, column INSTDATA.
You can write a simple program (either java or SQL plus) that would read the instance from the BLOB and measure the size.
And yes, with large instances you can have performance problems.

How to query the current instance size of an instance of a process

Hello guys,
I'm currently doing a Capacity Plan for my BPM enviroment and I would like to know the current instance size of different kind of processes deployed in my environment. I'll need this to calculate an average instance size per process. The main reason for this capacity plan is that our environment instance size is configured to more then 1000kb(don't know what kind of issues occurred in the past that led to this exceeded value configured) and I don't want to leave this configuration but I can't be safe decreasing it without know if our production environment will start launching the "Max Instance Size Exceeded" error.
Is there any way to fetch this information? Any API or SQL Query where I can find this information?
Thanks for any help.
Regards,
Luiz

How to measure the size of a string

windows app store how to measure the size of a string?
string str = "Hello word windows app store";

if you need the actual width the string occupies in pixels than use (see
this MSDN link for more details):
Graphics.MeasureString(String, Font)
if you only need the "length" of the string i.e. no. of characters than use (see
this MSDN link for more details):
str.Length
dont forget to bing / google :)
hope this helps!
Graphics.MeasureString(String, Font) can not use in windows store app.

How to measure the size of an object written by myself?

Hi all,
I'm going to measure the performance on throughput of an ad hoc wireless network that is set up for my project. I wrote a java class that represents a particular data. In order to calculate the throughput, I'm going to send this data objects from one node to another one in the network for a certain time. But I've got a problem with it- How to measure the size of an object that was written by myself in byte or bit in Java? Please help me with it. Thank you very much.

How to get the process instance key so as to retry a rejected task through api while ad provisoing?

Hi All,
How to get the process instance key so as to retry a rejected task through API while AD provisioing state?
API URL - http://docs.oracle.com/cd/E27559_01/apirefs.1112/e28159/toc.htm
Thanks

To retry a task that is in a rejected state, you use the SCH_KEY which is the task key. In OIM, all rejected tasks are listed in the OTI table. It contains all the important information about a rejected or pending task.
You can use the APIs found in the tcProvisioningOperationsIntf class to retrieve open tasks.

How to change the Task title on runtime?

Hi experts again,
My customer is struggling with something very simple: how to customize the Task title. You can certainly create an argument in the task, use Data Associations to map the argument, and then use XPath expression to get the value from the task payload and set it to the task title. That works fine. But it only executes once, when the process instance 'enters' in the task.
So once the Task is created, you can see the custom title in the Workspace.
Now, can we change the Title on runtime? I thought you could get the task payload, update the title and finally update the task but this does not seem to work. Here's the code that does it.
In this example, the priority is updated successfully but not the title.
FacesContext context = FacesContext.getCurrentInstance();
String tskId = (String)context.getApplication().evaluateExpressionGet(context,
"#{pageFlowScope.bpmWorklistTaskId}", String.class);
IWorkflowServiceClient workflowSvcClient = WorkflowService.getWorkflowServiceClient();
ITaskService taskSvc = workflowSvcClient .getTaskService();
ITaskQueryService wfQueryService = workflowSvcClient.getTaskQueryService();
IWorkflowContext wfContext = WorklistUtil.getWorkflowContextForASelectedTask();
Task myTask;
try {
myTask = wfQueryService.getTaskDetailsById(wfContext, tskId);
Element payloadElem = myTask.getPayloadAsElement();
System.out.println("****************" + myTask.getTitle());
System.out.println("****************" + myTask.getPriority());
myTask.setTitle("Task Title 3");
myTask.setPriority(2);
myTask.setPayloadAsElement(payloadElem);
taskSvc.updateTask(wfContext, myTask);
} catch (Exception e) {
e.printStackTrace();
The results which printed out in console after execute above code twice.
****************Task Title 1
****************3
****************Task Title 1
****************2

You can use the appropriately named Window Title property. In your project you can define conditional disable symbols (right-click on the project node and select Properties) and then use a conditional disable structure in your code. However, these symbols apply to the entire project, not to a specific executable. Thus, a better route would be to use the executable name (also accessible via a property), if possible, or some other distinction between the executables. What makes the executables different?

How to remove the tasks which are not manually recoverable?

How to remove the tasks which are not manually recoverable?
I tried performing manual recovery for the BPEL processes but there are few tasks which cant be manually recoverable..
Could you please tell me how to remove those tasks and also tell me which information in the console is the task_id in the database?

This article explains how to cleanup bpel process instances, you can find task instance id by searching for data in payload using api.

How to get the activity instance id and process id

Dear All,
For my case, my boss require the workflow program processor can be runtime assigned . After research, I found the coding example like below:
// dynamically assign a user to a role
rtm.addRuntimeDefinedUserToRole(
                  // process instance
                  prInstance,
                  // role name
                  "Processor",
                  // user that is assigned (IUser)
                  user,
                  // user context (IGPUserContext)
                  userContext);
// dynamically change the user assigned to a role for a particular task
String prInstanceID = prInstance.getID();
rtm.changeTaskProcessor(
                  // process instance ID
                  prInstanceID,
                  // activity instance ID
                  activityInstanceID,
                  // current user (IGPUserContext)
                  currentProcessorContext,
                  // new user (IGPUserContext)
                  newProcessorContext);
But I don't know how to get the process instance ID and activity instance ID before I can apply this api in my webdynpro application.
Any gentllement can give me an idea.
Thank you.

How to change the default window size display font size on Lync 2013 main window?

Hi champs,
Just a simple non-technical question: How to change the default window size display font size on Lync 2013 main window on Windows 7 desktop?
Thanks,

Hi,
Did you mean change the Lync: Change the Default Font and Color of Instant Messages just as Edwin said above?
If not, as I know, there is no natural way to change it.
If yes, on the latest version of Lync 2013 client, there is a new option “IM” on Lync client “Options” list. And you need to change the default Font and Color of IM in the interface of “IM”.

How to measure the baseline of a noisy, pulsed signal

Hi
I am measuring the torque exerted by a large motor on a shaft using a load cell and lever arm. The shaft runs at approx 150 rpm. I have attached a drawing that shows the output I get. This is a test rig.
I have written some code that measures the maximum peak out of a group of approx 5 peaks and writes this to a shift register. This gives me an idea of the maximum torque "spike".
I also wish to measure the baseline torque (due to the bearings in the machine). Even when highly filtered (my noise filter is set to 49Hz) the signal exhibits this noise which is probably due to vibration in the system. The signal is zeroed when the motor is not running.
Does anyone have an ideas on how to measure the "baseline" torque? The large spike in torque prevents me from doing a running average. Can anyone think of a way of averaging just the noisy part of the signal to get an average value? I aim to to subtract the average baseline torque from the peak value to get an idea of the torque due to the event which causes
the spike.
Any help would be greatly appreciated.
Many thanks.

Thanks for the reply. I understand what you are saying. However, I might have to modify my method for measuring the peaks if I choose to implement your idea. I have taken a screenshot of my "peak finder" code and attached it.
Bascially, the reset terminal is wired to a timer which outputs a pulse every few seconds. This resets the vi (a standard NI one I think) and sets the peak magnitude back to zero. This way, I am windowing the signal and measuring the maximum peak in every window. This is what I need to do.
So I could use a logical filter to feed data to the running average only if;
the amplitude of the signal is less than a certain threshold
and if the current value has similar low peaks either side of it
How would you construct the code to delay the evaluation so that the values in front and behind of the current data point can be analysed?
thanks again

I am using Oracle 9i... You might want to start with a feature of SQL*Plus: The AUTOTRACE (TRACEONLY) option which executes your statement, fetches all records (if there is something to fetch) and shows you some basic statistics information, which include the number of logical I/Os performed, number of sorts etc.
This gives you an indication of the effectiveness of your statement, so that can check how many logical I/Os (and physical reads) had to be performed.
Note however that there are more things to consider, as you've already mentioned: The CPU bit is not included in these statistics, and the work performed by SQL workareas (e.g. by hash joins) is also credited only very limited (number of sorts), but e.g. it doesn't cover any writes to temporary segments due to sort or hash operations spilling to disk etc.
You can use the following approach to get a deeper understanding of the operations performed by each row source:
alter session set statistics_level=all;
alter session set timed_statistics = true;
select /* findme */ ... <your query here>
SELECT
         SUBSTR(LPAD(' ',DEPTH - 1)||OPERATION||' '||OBJECT_NAME,1,40) OPERATION,
         OBJECT_NAME,
         CARDINALITY,
         LAST_OUTPUT_ROWS,
         LAST_CR_BUFFER_GETS,
         LAST_DISK_READS,
         LAST_DISK_WRITES,
FROM     V$SQL_PLAN_STATISTICS_ALL P,
         (SELECT *
          FROM   (SELECT   *
                  FROM     V$SQL
                  WHERE    SQL_TEXT LIKE '%findme%'
                           AND SQL_TEXT NOT LIKE '%V$SQL%'
                           AND PARSING_USER_ID = SYS_CONTEXT('USERENV','CURRENT_USERID')
                  ORDER BY LAST_LOAD_TIME DESC)
          WHERE ROWNUM < 2) S
WHERE    S.HASH_VALUE = P.HASH_VALUE
         AND S.CHILD_NUMBER = P.CHILD_NUMBER
ORDER BY ID
/Check the V$SQL_PLAN_STATISTICS_ALL view for more statistics available. In 10g there is a convenient function DBMS_XPLAN.DISPLAY_CURSOR which can show this information with a single call, but in 9i you need to do it yourself.
Note that "statistics_level=all" adds a significant overhead to the processing, so use with care and only when required:
