Mulitnumeric limits loading from database

Hi, Sir,
I am trying to use property loader step in TestStand to load multinumeric limits from a database table for different measurements in multinumeric test step. The database table has several columns such as: stepname, measurementname, hi/low limits. To load the limits for different measurement correctly using single property loader step, I have to match both the step name and measurement name in its filtering page. My question is how should I do this? More specific, how can I access the measurement name attached with different loading properties during run time?
I do not find any example for this problem. Most examples seem to be for TestStand 1.0, which has no multinumerica test step type.
Thank you for your help.

Yin,
In your database, you should have a column for each high and low limit and comparison for each multiple numeric limit test step. For example, if I have 2 measurements in my multiple numeric limit test step, I will have the following columns: StepName, Result_Measurement_0_Comp, Result_Measurement_0_Limits_High, Result_Measurement_0_Limits_Low,
Result_Measurement_1_Comp, Result_Measurement_1_Limits_High, Result_Measurement_1_Limits_Low.
After your database is set up, you would use the property loader step to read the values in during run-time. If you insert a property loader step and configure the Data Location to be a database, you can configure which database and table you want to read from. Then near the bottom of the property loader dialog, there are two fields. One is for Property Name and the other is for Column Name/Number. You use these fields to assign a certain column to a certain property. So for this case, we would choose one of the limit properties that we want to load from the database and assign that to a certain column. For example, the Property Name would be Result.Measurement[0].Comp and its corresponding Column Name/Number would be the database column Result_Measurement_0_Comp. The next Property Name would be Result.Measurement[0].Limits.High and its corresponding Column Name/Number would be the database column Result_Measurement_0_Limits_High. You would continue to assign a particular column to each property that you want to read in.
In using the Property Loader step type, it is immensely helpful to use the Import/Export Properties tool to create the database, Excel file, or text file because the tool will create these files with the correct format. You would then know exactly how many columns and their names because TestStand created them for you. Even if you plan to use a pre-existing source file, just creating the default source file will give you a better idea of how you will need to tailor your pre-existing database or excel or text file.
If you have other questions, let us know.

hey sorry for posting it in this forum.
but do u have sample code for making it work.. since i am able to do it on PDF format(image from Database and another stored in the webserver) using
byte image[] =(byte[]) outData.get("image");
                    ByteArrayInputStream img = new ByteArrayInputStream(image);
                    hmimg.put("P_PARAMV3", img);

Error loading from database

I have a .wft file and two databases: Deploy and Production.
If I save the .wft file to Production it works fine but if I save it to Deploy I get when Uploading from database:
1300: Could not load.
1114: Could not load from database.
1115: Could not load all definitions referenced by 'CON_MAIL' item type.
1115: Could not load contents of 'CON_MAIL' item type.
1101: Could not load item types from database. FILTER=CON_MAIL
210: Oracle Error: ORA-01403: no data found
. SQL text: SELECT protect_level, custom_level, name, display_name, description, type, subtype, format, text_default, to_char(number_default), to_char(date_default, 'YYYY/MM/DD HH24:MI:SS') FROM wf_item_attributes_vl WHERE item_type = :type ORDER BY sequence
It did not create in deploy the row in the table wf_item_attributes and I think this is not a NLS_LANG problem because the same file worked in Production DB (they have the same environement).
Any solution? I could create process in Deploy until one month ago.
Thanks in advance JR

José,
Por tu nombre asumo que hablas español por lo que te escribo en ese idioma.
En nuestro caso, como el mensaje de error indicaba que el siguiente query generaba problemas, lo analizamos
SELECT protect_level, custom_level, name, display_name, description,
type, subtype, format, text_default, to_char(number_default),
to_char(date_default, 'YYYY/MM/DD HH24:MI:SS')
FROM wf_item_attributes_vl
WHERE item_type = :type
ORDER BY sequence
Encontramos que la vista wf_item_attributes_vl se basa en las tablas WF_ITEM_ATTRIBUTES y WF_ITEM_ATTRIBUTES_TL
El problema se generaba porque en la tabla WF_ITEM_ATTRIBUTES había un registro que no tenía su correspondiente en la tabla WF_ITEM_ATTRIBUTES_TL (considerar que la vista wf_item_attributes_vl filtra los datos de acuerdo al lenguaje de la sesión, usando userenv('LANG') )
Creando el registro faltante en la tabla WF_ITEM_ATTRIBUTES_TL, los datos del atributo aparecieron en la vista wf_item_attributes_vl, y el problema desapareció.
En nuestro caso el verdadero problema se originó por haber manipulado los datos de definición de atributos directamente desde las tablas y no a través de WF Builder

ImageIcons loaded from database don't appear

Hi,
I create a JavaBean to show images from filesystem and database (oracle9i) in a JTable.
The ImageIcons loaded from filesystem appears fine whith my defined DefaultTabelModel.
The ImageIcons read from database (jdbc2) with the same DefaultTabelModel appears in the correct count, but the fields or placholders of the Images, saved as blob, are blank.
The code of my resultset
BLOB myblob = null;
int bufsize = 0;
while(result.next())
myblob = ((OracleResultSet)result).getBLOB("image_container");
bufsize = myblob.getChunkSize();
byte[] buffer = new byte[bufsize];
ImageIcon icon = new ImageIcon(buffer);
Object [] row = {icon};
model1.addRow(row);
model1.fireTableDataChanged();
I don't get any errors.
Thanks
Klaus

Hi,
I changed the datatype from BLOB to 'LONG RAW' for the image in the database.
while(result.next())
byte[] bytes = result.getBytes(1);
String jd = String.valueOf(bytes);
System.out.println(jd);
//get:[B@153 [B@154
//or [B@155 [B@156 for the 2.result
String name = result.getString(2);
System.out.println(name);
//get the correct result
FileOutputStream file = null;
file = new FileOutputStream ("c:\\"+name+".jpg");
file.write(bytes);
//it works fine !!!
ImageIcon icon = new ImageIcon(bytes); //it is correct ?
String ls = String.valueOf(icon.getImageLoadStatus());
String h = String.valueOf(icon.getIconHeight());
String w = String.valueOf(icon.getIconWidth());
System.out.println(h+" : "+w);
//get: -1 : -1
System.out.println(ls);
//get: 4
Object [] row = {icon,name};
//icon is blank, name appears correct in jtable
//but when I need:
//ImageIcon icon = new ImageIcon(AW_Frame.class.getResource("images/emac.jpg"));
//icon and name appears correct in jtable
model1.addRow(row);
model1.fireTableDataChanged();
any ideas ?

Error while Image loading from database

I'am using generic handler for loading Image from data bases. Its work fine when when I hardcode the ImageID in QureyString when call Handler. But it's giving errors of different type when I dynamically pass value to qurey string(from datatable).
"There is already an open DataReader associated with this Command which must be closed first."
OR
"There is already an open DataReader associated with this Command which must be closed first."
here is a code of Handler
public void ProcessRequest(HttpContext context)
Int64 id = Convert.ToInt64(HttpContext.Current.Request.QueryString["adid"]);
// dt = obj_dalayer.GetRecpDetailsByID(id);
dt=GetRecpDetailsByID(id);
if (dt.Rows.Count > 0)
//context.Response.ContentType = "image/jpeg";
context.Response.BinaryWrite((byte[])dt.Rows[0][2]);
public DataTable GetRecpDetailsByID(Int64 reid)
try
obj_DB.Open();
obj_sqlcmd = new SqlCommand("GetRecpDetailsByID", obj_DB.GetDBConnection());
obj_sqlcmd.CommandType = CommandType.StoredProcedure;
obj_sqlcmd.Parameters.Add(new SqlParameter("@rid", reid));
obj_sqlda = new SqlDataAdapter();
obj_dt = new DataTable();
obj_sqlda.SelectCommand = obj_sqlcmd;
obj_sqlda.Fill(obj_dt);
return obj_dt;
finally
obj_DB.Close();
And here is a HTML and ServerSide code on ASPX page of call handler.

I'm using Eval("ReID") to get ID of Image from datatable.

Ayez,
This is the VB forum, try it in the C# form.

Any reason why you are adding the "jpeg" to the end of the byte array?
You should only have to pass the byte array to the ImageIcon constructor.

Could not load data from database after adding a query

Dear all,
I have a working crystal reports 2011 report. This report get its data from a BW 7.01 system provided by three bex queries. Everything works as expected but not I have to add a fourth query to the report then I get the following messages:
I try to translate it because I user the german version:
INFORMATION: In this report a stored procedure is used. Ensure that no SQL expression was added and no grouping on server side will be done.
WARNING: Data could not be load from the database.
WANING: Invalid argument provided. Details: The key figure structure isn't a valid field for report generation. Use instead the real keyfigures with teir units.
Has anyone an idea what can be the reason for my issue?
Thanks and regards!

hi Gerrit,
a couple of questions...
1) are you adding all 3 queries (and then the 4th) in the same data connection or are each of these additional queries in a subreport?
2) if all 3 queries (and then the 4th) are in the same data connection are you linking them?
3) most importantly, if you create a brand new report off of the 4th query, is it successful?
it's been quite a while since I've worked with bex queries but in general adding multiple queries (or stored procs or commands or combinations thereof) to the same report is probably not a good idea. there ends up being a lot of processing happening in the crystal reports designer itself as a large virtual record set is created by the individual queries.

Load interactive pdf with data from database

I am trying to understand our options for loading database data into an interactive pdf..?   Some of the data is not stored in the database and needs to be manually entered by the user in the interactive pdf.
Here is the interactive pdf I'm working with:
http://www.dcma.mil/dcman/NPP/files/dd1149.pdf
As I understand it, there are 2 options:
1. Create an xml file from the database data.   Users can manually import this xml file into this existing interactive pdf and then manually add the additional data, and save the interactive pdf.
Would users need to use Adobe acrobat Standard or Pro edition to import the xml data?
2. Create a XFA PDF form that's made with LiveCycle Designer.   Can this method create an interactive pdf so that users can enter additional data later and save the pdf?
   What adobe products are required to use this method?
thanks for any assistance..
-D

Yes,using LiveCycle you could accomplish this easily.Once you have your invoice form ready based on predefined XSD, you can easily update the form data by fetching the values from database using JDBC operation.Also you could email this updated form using Email service.
Thanks,

Pre-loading the Cache from Database during application start-up

We are using Spring, Hibernate, Oracle Coherence 3.5.2 Weblogic Webservices
Our requirement is to pre-load the cache during the application start-up most probably during Authentication/Authorization Service is invoked.
We plan to load the data for other services from database into Coherence cache so that whenever user access that particular service he ends up hitting the Cache instead of database.
We would greatly appreciate sample code snippets on how to write CacheInitializerBean with marker to demonstrate the state of cache.

Hi Rob,
Thanks for pointing to the article: Pre-Loading the Cache
In fact i already looked at that article before posting. It just mentions how to load the data from database into Cache.
What i am looking for is how to make this happen during application start-up. This is my first hurdle.
The second one is as mentioned in the article http://coherence.oracle.com/display/COH35UG/Pre-Loading+the+Cache
i wrote following code which never gets populated into cache. Not sure whats going wrong even though i see Hibernate loadAll() method loading all the objects in the console
public   void populateCache() throws SQLException
    Map<Long, Object> buffer = new HashMap<Long, Object>();
    int count = 0;
     List<Contract> contractList = this.getHibernateTemplate().loadAll(Contract.class);
     log.debug("contractList size="+contractList.size());
     for(Contract contract : contractList)
         Long key   = new Long(contract.getId());
         Object value = contract;
         buffer.put(key, value);
         // this loads 1000 items at a time into the cache
         if ((count++ % 1000) == 0)
              contractCache.putAll(buffer);
             buffer.clear();
     if (!buffer.isEmpty())
          contractCache.putAll(buffer);
    }We would greatly appreciate your time in helping us resolving two hurdle blocks.

Please help me,
i am having a jsp page which contains a form
with a textfield ,two dropdown list
and a submit button
when i select a list from first drop down, second drop down has to
be loaded from the database dynamically according to the
selected one in the first drop down.
i gave onselect event for the first drop down and
gave this one
temp=first dropdown selected value
self.location='currentfile+query='+temp;
after this current page is reloading, but the already existing
values in textfield and first selected value in drop down list is
missing.
how to solve this problem? and the rest of the problem. i mean
loading the data into second drop down list.

in first <selcet> tag write Onchange and submit to the jsp then the values will return in second select box.
