String returned when no line is found

• Empty string returned after receipt gpib

  Nobody knows why, I would periodically get an empty string returned after the issuance of a receive().  It is originally a big delay in my program that I can't really afford to have. The delay occurs while the front desk manages the empty string. This sequence works fine most of the time.

  VB code:

  Public void GetData (GPIBAddress, SendString) As String
  Dim ReadThis AsString, RPD As Integer, ReadTemp As String
  read:
      
  Call Send (0, GPIBAddress, SendString, NLend)
  Wait (500)
  Call ReadStatusByte (0, GPIBAddress, RPD %)
      
  ReadThis = Space$ (140)
      
  Call Receive (0, GPIBAddress, ReadThis, STOPend) I get an empty string here, not always.
      
  If Trim (ReadThis) = "" then to correct, I issue this sequence.
  Call DevClear (0: 26)
  GoTo review
  End If
      
  GetData = ReadThis
  End Function

  OR SPY:

  See attachment.

  I'm talking to a Keithley 2612.

  I use NI488.2 2.73

  In your code snippet, I see where you made a ReadStatusByte, but the result is not checked. When considering the capture of Spy file, where the reception work, the ReadStatusByte returns the result of "0 x 04", as noted in the attached bitmap, ReadStatusByteWithMAV.gif. This result is known as the VMR (Message available) bit. If 4 (MAV bit) Bit is set, which indicates that there is something in the output queue which can be read. Information about the parameters of the ILO for a Keithley 2612 can be found starting on Page 655 by the section called, Status byte and service request (SRQ) in the reference manual. Here is a link to the reference manual:

  http://www.Keithley.com/data?asset=52057

  In the case of the reception fails (line 63 in the capture file), result of the previous call of the ReadStatusByte was '0x00' (as shown in the attached picture, ReadStatusByteNoMAV.gif), which means that there was nothing in the output queue to read.

  After a ReadStatusByte, you should check the result to see if there is something in the output queue to read. If the result is "0x00", then you can probably do something like add a delay and keep control of the ReadStatusByte again until the ReadStatusByte is back with 4 bits set. When Bit 4 is set, you can do a front desk to read the output queue.

  Hope this information is useful.

• Search for value in the subset of data and returns a single line.

  Hello

• Add LogFilter match string for the subject line of the e-mail notification

  Hello

  On the LogFilter alerts, I add the matching string in the subject line of the e-mail logfilter alert notification. I followed KB 75058 for this requirement. But I'm getting other data also with the match string. Please find the attached screenshot. The chain is marked in yellow. I don't need data which is marke red din. Can you let me know if a setting can be done in the script that retrieves the hitstring so that only the histstring appear

  FMS: 5.6.4

  Kind regards

  Roshan.

  • HitString.txt.zip
  • Logfile.PNG

  Hi Roshan

  We do something similar.  We have configured a Message appropriate for each matching string user:

  

  Then, in the rule Condition, I created an expression UserError containing the following:

  def controls = checkObservationAlarms (#LogFilter_ErrorVerbose to 1ms #,)

  {the entry->

  If (entry.get ("Severity") == "WARNING") {}

  return 2;

  }

  If (entry.get ("Severity") == 'CRITICAL') {}

  return 3;

  }

  If (entry.get ("Severity") == "FATAL") {}

  return 4;

  }

  return 0;

  },

  {entry, severity-> {switch (severity)}

  case 2:

  Return entry.get ("User_Message");

  case 3:

  return "" + entry.get ("User_Message") + "";

  case 4:

  return "" + entry.get ("User_Message") + "";

  by default:

  Return ' ';

  }}, @foglight_rule_id);

  If (checks.size () > 0) {}

  return checks [0] [1];

  } else {}

  Return ' ';

  }

  By referencing @UserError in the subject line, I get the Message to the appropriate user.

  I also do a similar thing for the severity of error appropriate in my subject line.

  Hope this helps

• How to filter data according to internal application and in case if returns nothing outside the query must return all the lines

  create table ab (a number, b varchar2 (20));

  Insert into ab

  Select rownum, rownum. "" sample "

  of the double

  connect by level < = 10

  create table bc (a number, b varchar2 (20));

  Insert into BC.

  Select rownum + 1, rownum + 1 | "" sample "

  of the double

  connect by level < = 10

  Select * AB

  where b in (select b BC where b = "2sample")

  This query will return me 1 row, but there are cases where the value of the parameter b is null

  and that it should return all rows in the table

  as

  Select * AB

  where b in (select b BC where b = "2sample")

  which return specific values, but I want to change in a way when the inner query returns nothing then outer query should return all the lines and works as

  Select * AB;

  Is it possible to put in a single query

  Hello

  You seem to ask for different things.  You want all the lines AB when

  1. The parameter ("2sample' in the example) is NULL, or when
  2. There is no corresponding row in the 2 tables (which could happen even if the parameter is not NULL)

  ?

  Assuming you want the option 2, here's one way:

  WITH got_rnk AS

  (

  SELECT ab.*

  DENSE_RANK () (ORDER IN CASE

  WHEN b (IN)

  SELECT b

  BC.

  WHERE b = "2sample" - parameter

  )

  THEN "A".

  OF ANOTHER 'B '.

  END

  ) AS rnk

  AB

  )

  SELECT a, b

  OF got_rnk

  WHERE rnk = 1

  ;

  This does not assume b is unique in each table.

  Thanks for posting the CREATE TABLE and INSERT statements; It is very useful.

• How to automatically complete a transitional according to the value of another attribute when attribute line is questioned in the VO?

  Hello world

  The task seems simple enough, but I have not found a way to populate an attribute transitional according to the value of another attribute when the line is queried. What is the best way to achieve this?

  Thank you.

  James

  Use VORowImpl, if you have any transient attributes defined in the view object, whose value is derived from other attributes of the line, you can override the GET method and add logic there

  Please note that this class represents a row in the results collection in a display object.

  The error message "no more virtual tiles can be allocated" appears when I try to use the effects in the quick edit mode in my 13 elements. The OK wand has to press several times for loading all effects models. The error returns when you select the particular model.

  The problem does not appear, if PH 13 items is run in administrator mode.

  The available computer resources are rather big enough: INTEL CPU i7 4 cores, 16 GB RAM, 1 TB HDD + 32 GB SSD, Windows 8.1.

  Please, advice how to fix this problem? Perhaps, there is patch or update available?

• How to pass an xml CDATA in the string element when OSB call a webservice?

  How to pass an xml CDATA in the string element when OSB call a webservice?
  
  I have a business service (biz) this route to exploitation of a Web service.
  
  An example of this legacy Web service request:
  < soapenv:Envelope xmlns:soapenv = 'http://schemas.xmlsoap.org/soap/envelope/' xmlns: ex = "example" >
  < soapenv:Header / >
  < soapenv:Body >
  < ex: run >
  < ex: arg > <! [CDATA [< searchCustomerByDocumentNumber >
  < documentNumber > 12345678909 < / documentNumber >
  [[< / searchCustomerByDocumentNumber >]] > < / ex: arg >
  < / ex: run >
  < / soapenv:Body >
  < / soapenv:Envelope >
  
  type ex: arg is a string.
  
  How to pass this structure CDATA webservice in OSB?

  Steps to resolve this problem:
  1 create an XML schema. For example:
  
  
  elementFormDefault = "unqualified" >

  
            
                 
                      
                           
                           
                      
                      
                           
                      
                 
       
       
       
       
  

  With this XSD, XML can be generating:
  
  
  documentNumber
  

  2 create an XQuery query to create a ComplexType searchCustomerByDocumentNumber. For example:
  (: pragma bea: element global-element-return = "searchCustomerByDocumentNumber" location = "searchCustomerByDocumentNumber.xsd" ::))

  declare namespace xf = "http://tempuri.org/NovoSia/CreateSearchCustomerByDocumentNumber/";

  declare function xf:CreateSearchCustomerByDocumentNumber($documentNumber_as_xs:string)
  as {(searchCustomerByDocumentNumber)}
  
  {$documentNumber}
  
  };

  declare the variable $documentNumber as XS: String external;

  XF:CreateSearchCustomerByDocumentNumber ($documentNumber)

  3. in your step in proxy pipeline add to assign the created the XQuery function call from the number of the document of your payload.
  Assign to a variable (for example: called searchCustomerByDocumentNumberRequest)

  4. create an another Transformation of XQuery (XQ) to create a request to the existing Web service. For example:
  {fn - bea: serialize ($searchCustomerByDocumentNumberRequest)}

  For more information about xquery Serialize function:
  41.2.6 fn - bea: serialize()
  You can use the fn - bea: serialize() function if you need to represent an XML document as a string instead of as an XML element. For example, you can share an XML document through an EJB interface and the EJB method takes the string as an argument. The function has the following signature:

  FN - bea: serialize($input as item()) as xs: string
