How Data stores in Xi?

hi..
How the data in SAP-Xi stores and where?

Hi,
I think we are getting a little confused here. Let me answer this qn from my view point. For PI 7.0 atleast. We are using Usage Type PI. So technically it sits on top of ECC. So ECC has a database which could be Oracle, DB2 or SQL Server. When data is send to ECC ist gets updated into the corresponding database. In the db there are different types of tables, like for ABAP and JAVA. So when the corresponding data is being fed into SAP, it goes and updates against the db tables. So even in PI also, the same fashion is being followed. Even more than that I assume that since there is no place to data to be saved in SAP as a whole, db is the only place in which data can be stored. This strengthens my opinion to a level. Now, I am not sure abt the contents of Cache, but to my level of thinking, Cache is a short term memory configuration that is used for storing data. I would like to draw a comparison to log files of db's. Likewise, eventually the contents would also be updated against the db tables. This is my view point and it is by no means exhaustive, So please feel free to pitch new ideas if any,
Thanks

How data stores in info object

Hi all
How can an Infoobject characteristic created without master data and texts.And in same wayi need to store the data in the infoobject
regards
ashwin

Hi Ashwin,
Normally while creating(Activating) info object in background tables has been created for each one.
Suppose for example you IO name is like this ZIO_MID
for this info object the Master data table will be like this,
/BIC/MZIO_MID --> Master data view
/BIC/PZIO_MID --> Time independent object
/BIC/QZIO_MID --> Time dependent object
For SID tables will be created like this,
/BIC/SZIO_MID --> SID table view
/BIC/XZIO_MID --> Time independent sid object
/BIC/YZIO_MID --> TIme dependent object
For this object Text table will be created like this,
/BIC/TZIO_MID --> Text table view
you can directly enter these table name in SE11 and you can directly insert your values also.
While creating infoobject you can unselect those options of "WIth Master data" and " With Texts" .
If you want to maintain data within this objects , Right click your info object maintain master data and execute and click create button , Insert your values.
NOTE: Assign points if it helps

How to store this value in date variable?

Hi sir,
i am having one query which is
select to_char(date '1900-01-01' + 1439/(24*60),'DD/MM/YYYY HH24:MI:ss')from dual;
when i am running this query i am getting this value: 01/01/1900 23:59:00
and this value i am inserting in one variable which has date datatype.
here i am storing like this:
v_nshiftmax := to_char(date '1900-01-01' + 1439/(24*60),'DD/MM/YYYY HH24:MI:SS');
while storing getting error: not a valid month
how to store it in this variable?
thanks

why using TO_DATE (), to improve performance avoid function calling if you can do without it, just use v_nshiftmax := date '1900-01-01' + 1439/(24*60); remove TO_CHAR() function only, as you already converted it to date.Please prove to us that TO_DATE(...) is slower that using DATE '...'
Both are internal functions that take a string and turn it into a date.

How to store multiple data in one aray at one go?

Hi i am creating a Recipe Cooking Book and i have got a recipe class, ingredient class, equipment class and jFORM GUI. the gui form will have a list and it will contain couple of equipments. the user should be able to select more than 1 equipments which would use the pass- by - value to the recipe class and it will be passed to equipment class.
The problem that encounter is that when i have to select multiple values from list, it should store all selected equipments to array.
This is where i am stuck as i don't know how to store couple of equipment at one creation.
This is my recipe constructor in recipe class
public Recipe(int aRecipeID, String aRecipeName, String aCountryofOrigin,
                  String aType, String aPreparationTime, String aCookingTime,
                  String aRecipeDescription, String aProcedure,
                   ClsEquipment[] aequipment, String aImage1, String aImage2,
                  String aImage3) {
        Create(aRecipeID, aRecipeName, aCountryofOrigin, aType,
               aPreparationTime, aCookingTime, aRecipeDescription, aProcedure,
               aequipment, aImage1, aImage2, aImage3);
    public void Create(int aRecipeID, String aRecipeName,
                       String aCountryofOrigin, String aType,
                       String aPreparationTime, String aCookingTime,
                       String aRecipeDescription, String aProcedure,
                        ClsEquipment[] aequipment, String aImage1, String aImage2,
                       String aImage3) {
        RecipeID = aRecipeID;
        RecipeName = aRecipeName;
        CountryofOrigin = aCountryofOrigin;
        Type = aType;
        PreparationTime = aPreparationTime;
        CookingTime = aCookingTime;
        RecipeDescription = aRecipeDescription;
        Procedure = aProcedure;
        *equipment[j] = aequipment[k];*
        Image1 = aImage1;
        Image2 = aImage2;
        Image3 = aImage3;
this is The command that i have in Jform gui
    public void jRcreateButton_actionPerformed(ActionEvent e) {
        int i=0;
myRecipe.Create(Integer.parseInt(jRidTextField.getText()),jRnameTextField.getText(),jRcountryTextField.getText(),jRtypeTextField.getText(),jRptimeTextField.getText(),jRctimeTextField.getText(),jRdescriptionTextArea.getText(), jRprocedureTextArea.getText(),new ClsEquipment(jAEequipmentList.getSelectedValues()),jRimage1TextField.getText(),jRimage2TextField.getText(),jRimage3TextField.getText());
Let me conclude what i am trying to do. Basically i want the user to select more than 1 equipments from the List and the user should also input other recipe data. once this is done, the should click on create.
when creating one recipe, u need more than 1 equipment so that created recipe should store selected equipments, which i will later on retrieve and display on screen.
can u please guide me where i am goin wrong and how i could fix it.
thank you in advance
Edited by: JAVABABY on Feb 18, 2008 8:40 AM

       *equipment[j] = aequipment[k];*JList's getSelectedValues() method returns an array of Objects, so if you wanted to store it into another Object[] reference, you'd just use
equipment = aequipment;But, you are storing it as an Equipment array, so you'll need to loop over the Object array and cast each element to an Equipment reference, and store it into the Equipment array. Something like this:
equipment = new Equipment[aequipment.length];
for (each element x in aequipment) {
    equipment[x] = (Equipment)aequipment[x];
}

How can I transfer data form one data store to another iview /dats store

Hello,
I have two iview and want to transfer the data from my data store (main iview) to the nested iview (or the data store in nested iview)
Can you give me instructions, how I can implement this with the signal in and outports.
Thanks
Bst regards
thomas
I

Hi Thomas
Pass the output data of one iview to another(by connecting the output of the 1st to the input of the 2nd) and then Signal Out the combined data of the two iviews from the 2nd iView using a event(say, a submit button) from the 2nd iView.
Connect the signal out to the nested iView(main iView) by composing a Signal In on the nested iView.
Next, inside the nested iView design layout push the values from Signal In to a data store.
Now you could access all the data @datastore from any no. of forms inside the nested iViews.

How to store bit data in VARCHAR(4000) field?

Hi.
Please help!
We are porting some C/C++ software with embedded SQLs from NT/DB2 to Linux/Oracle.
On NT/DB2 we have some table to store file data in a VARCHAR(4000) blocks.
Table looks like this
CREATE TABLE FileData (filetime as timestamp not null, idx int not null, datablock varchar(4000) FOR BIT DATA not null, primary key (filetime, idx) );
As you can see DB2 has appropriate field modifier - "FOR BIT DATA" which makes DB2 storing data as-is, not converting characters.
I need to know - if it is possible to do the same in Oracle like in DB2?
If Oracle has some kind of field modifier like "FOR BIT DATA" in DB2?
If not, how can I do the same in Oracle?
The current problems are:
1) when application imports the file with some national chars the Oracle stores "?" in a database in place of national chars.
2) another piece of a problem - if file is more than 4000 bytes length, it reports the ORA-01461 error (see it is trying to expand some chars to UTF8 char which is not fit a single char, so finally - not fit the field size).
So, it seems that it cannot proceed national chars at all. :-\
For details please see enclosed [C code|http://dmitry-bond.spaces.live.com/blog/cns!D4095215C101CECE!1606.entry] , there is example how data written to a table.
In other places we also need to read data from FIELDATA table and store back to file (other filename, other location).
Here is summary on a field-datatype variants I have tried for the "datablock" field:
1) VARCHAR2, RAW, LONG RAW, BLOB - does not work! All reports the same error - ORA-01461.
2) CLOB, LONG - both working fine but(!) both still returns "?" instead of national chars on data reading.
Hint: how I did try these field types - I just drop the "FileData" table, created it using different type for "datablock" field and run the same application to test it.
I think I need to explain what the problem - we do not provide direct access to Oracle database, we use a some middle-ware. Middle-ware is a C/C++ software which also has a interface for dynamic SQLs execution. So, exactly this middle-ware (which is typically running on the same server with Oracle) receives the "?" instead of national chars! But we need it to return all data AS-IS(!) without any changes!!! That is wjhy I did ask - if Oracle has any options to store byte-data as-is?
The BIG QUESTION - HOW CAN WE DO THIS?!
Another thing I need to explain - it is ok to use Oracle-specific SQL ONLY IF THERE IS REALLY NO WAY TO ACHIEVE THIS WITH STANDARD SQL! Please.
So, please look on a C code (by link I have posted above) and tell - if it is possible to make working in Oracle the VARCHAR approach we using at the moment?
If not - please describe what options do we have for Oracle?
Regards,
Dmitry.
PS. it is Oracle 11gR2 on CentOS 5.4, all stuff installed with default settings, so Oracle db encoding is "AL32UTF8".
C/C++ application is built as ANSI/ASCII application (non-unicode), so sizeof(char)=1.
The target Oracle db (I mean - the one which will be used on customer site) is Oracle 10g. So, solution need to be working on Oracle 10g.

There is some contradiction in your requirements:
- if you want to store data as is without any translation use RAW or BLOB
- if you want to store national character data try to use NVARCHAR2 or NCLOB.Seems you did not understand the problem. Ok, I'll try to explain. Please look on the code sample I provided in original question
(I just added expanded data structures there, sorry I forgot to publish them when post original question):
EXEC SQL BEGIN DECLARE SECTION;
struct {
 char timestamp[27];
 char station[17];
 char filename[33];
 char task[17];
 char orderno[17];
 long filelen;
gFilehead;
struct {
 char timestamp[27];
 long idx;
 struct {
 short len;
 char arr[4001];
 } datablock;
gFiledata;
EXEC SQL END DECLARE SECTION;
#define DATABLOCKSIZE 4000
#ifdef __ORACLE
#define VARCHAR_VAL(vch) vch.arr
#elif __DB2
#endif
short dbWriteFile( char *databytes, long datalen )
short nRc;
long movecount;
long offset = 0;
gFilehead.filelen = gFilehead.filelen + datalen;
while ((datalen + gFiledata.datablock.len) >= DATABLOCKSIZE)
 movecount = DATABLOCKSIZE - gFiledata.datablock.len;
 memcpy(&VARCHAR_VAL(gFiledata.datablock)[gFiledata.datablock.len], databytes, movecount);
 gFiledata.datablock.len = (short)(gFiledata.datablock.len + movecount);
 exec sql insert into filedata (recvtime, idx, datablock)
 values(
 :gFiledata.recvtime type as timestamp,
 :gFiledata.idx,
 :gFiledata.datablock /* <--- ORA-01461 appears here */
 nRc = sqlcode;
 switch (nRc)
 case SQLERR_OK: break;
 default:
 LogError(ERR_INSERT, "filedata", IntToStr(nRc), LOG_END);
 exit(EXIT_FAILURE);
 offset = offset + movecount;
 datalen = datalen - movecount;
 gFiledata.idx = gFiledata.idx + 1;
 memset(&gFiledata.datablock, 0, sizeof(gFiledata.datablock));
 databytes = databytes + movecount;
 gFiledata.datablock.len = 0;
if (datalen + gFiledata.datablock.len)
 memcpy(&VARCHAR_VAL(gFiledata.datablock)[gFiledata.datablock.len], databytes, datalen);
 gFiledata.datablock.len = (short)(gFiledata.datablock.len + datalen);
return 0;
}So, the thing we need is - to put some data into the "datablock" field of following structure:
struct {
 char timestamp[27];
 long idx;
 struct {
 short len;
 char arr[4001];
 } datablock;
gFiledata;Then insert it into a database table using static SQL like this:
 exec sql insert into filedata (recvtime, idx, datablock)
 values(
 :gFiledata.recvtime type as timestamp,
 :gFiledata.idx,
 :gFiledata.datablock /* <--- ORA-01461 appears here */
 ); And then expect to read exactly the same data back!
The problems are:
1) Oracle make decision to convert the data we are inserting (why? and how to disable converting?!)
2) even if it inserts the data (CLOB and LONG field datatypes are working fine when inserting data with such static SQL + such host variable) then it became not readable! (why?! how to make it readable?!)
P. Forstmann wrote:
ORA-01461 could mean that you have a wrong data type for bind variable variable in your client code:Not me decided that host variable is the "LONG datatype value" - the Oracle make that decision instead of me. And that is the problem!
Looks like Oracle react on any char code >= 0x80.
So, assume if I run the code:
// if Tab1 was created as "CREATE TABLE Tab1 (value VARCHAR(5))" then
char szData[10] = "\x41\x81\x82\x83\x84";
EXEC SQL INSERT INTO Tab1 (value) VALUES (:szData);
Oracle will report the ORA-01461 error!
EXACTLY THIS IS THE PROBLEM I HAVE DESCRIBED IN MY ORIGINAL QUESTION.
So, problem - why Oracle make such decision instead of me?! How we can make Oracle insert data into a table AS-IS?
What other type of host variable we should use to make Oracle think that data is a binary?
void*? unsigned char? Could you please provide any examples?
Ok, you did recommend - "use the RAW datatype". But RAW datatype is limited to size 2000 bytes only - we need 4000! So, it is not match our needs at all.
Also you have mentioned "use BLOB" - but testing shows that Oracle reports the same ORA-01461 error on inserting data into a BLOB field from such host variable! (see the code I posted)
What also we can do?
Change type of host variables? BUT HOW?!

How to store data (in tdm files)

I'm looking for advice on how to store data in tdm/tdx files.
The main challenge is like this: At regular time intervals there is new data available (say every 10 minutes there are 10 minutes of new data available). All data is time based. So every ten minutes I may create a new tdm/tdx file containing this data segment. However, when i want to analyze the data i dont necessarily want to view 10 minutes of data from all channels, but maybe 20 hours of data from one particular channel.
The way I've achieved this so far is to manually load each 10 minute segment of this particular channel and then add these parts together. This is both time consuming and cumbersome. Is there a better way to do this that I've simply not discovered yet? Is there a better way to store data to simplify this process?
One solution is of course to save data from several 10-minute frames in one file, but seeing as there is a never ending supply of data i cant simply save all data in one giant file, it has to be split up at some point, and the problem will still remain.
One factor to have in mind here is that this is rather large amounts of data (maybe 10GB each day), so the option to simply load all the data into memory goes out the window rather quickly.
Feel free to ask if I've not made myself very clear

Hi salte,
If your test ever ended, and if you had LabVIEW 8.20 or higher, I would recommend using a TDMS file, which handles data appeands flawlessly. DIAdem 10.1 now also does data reduction and index windowing during file loading for TDM / TDMS / DataPlugin files, so that you could easily load out only the part of the file you wanted to look at. But since you describe your data acquisition as never stopping and amassing 10 GB per day, I agree that it would be impractical to use only 1 data file. So we are stuck with some number of files which each contain a part of your measurement. This approach can have advantages, since you can save operational properties for each "buffer" such as average value, dominant frequency, ambient room temperature, etc., and later on you can use the DataFinder to query out only the data buffers which meet specific conditions based on these properties. The problem remains to load and assemble data based on multiple files. This is an old problem in DIAdem, and one for which I have an efficient and I hope satisfactory workaround application. It does what you describe already doing in the minimum amount of time and with the minimum amount of user interaction, and it can be highly parametrized to suit your particular situation. The ideal way to start the application would be as part of a ResultsList custom menu. This would enable you to query out the buffers you wanted, highlight those rows in the ResultsList, right-click and choose your custom menu, and WHAM! the selected buffers for your queried channel(s) are automatically appended together in the DataPortal. Launching from a ResultsList custom menu would mean that you could skip the file dialog and just read out the data sources directly from the ResultsList selection.
Let me know what you think,

How to store jsp session data of different user in util.hashmap

how to store jsp session data of different user in java.util.hashmap
and access the data of all user on the server side
The same example is given in professional jsp but its not working.
I can use getIds() of httpsessioncontext but it's depricated

Hi
I'm trying to make an example.
With the following codes you can get the date from the session.
request.getSession().getAttribute("sessionname")
To store it in a hashmap you could do it like this ->
Hashmap hm = new Hashmap();
hm.put(Object key, request.getSession().getAttribute("sessionname"));
I hope you understand it if not just write it!

You can't just display data from a text file in a JTable. You have you understand the structure of the data so that you can parse the data and create a table model that can access the data in a row/column format. Here is an example of a simple program that does this:

How to Set a Variable with data from Srouce Data Store

Hello ODI Experts,
I have created a Physical & Logical Schema and a Source Data store to pickup data from a database table.
On the other hand, I have a few variable that I will pass in a web service call (ODIInvokeWebService tool).
Would yo please guide how I can set variables from my source data store.
Thanks & Regards,
Ahsan

Hello Bos/Damodhar/ODI Experts,
Doesn't it gives me a less optimized approach picking one column per query (per variable)?
Lets say, I have to pick 35 columns from a table and put those in 35 variables...It would mean running 35 queries for fetching one record from the database table.
Doesn't it seem less performance effective (less optimized)..a little scary..any thing better that I can do to make it more optimized?
Another question, what if multiple new values have come in the DB table, since I am using Refresh Variable, would this variable have multiple values in it?
Thanks for all your help,
Ahsan

Persistence data store...how to

Greetings!
I have a JMS application that I am developing using durable subscribers connecting to my Topic. Everything works like a charm, so now I want to extend capability ( aka, break my application =P ). I've read a bunch of documentation that says JMS has the capability to store these messages to a flat file or a database, but that's the extent of the documentation I can find.
I am wondering if, specifically, someone can tell me HOW do I configure where the messages get stored. Do I have to write code to store these messages to a database or is this functionality implicit within my application server (WebSphere 5)?
If someone could explain this voodoo magic to me or point me to a doc that explains it, I would be greatly appreciative!
Thanks in advance!
Matt,
JMS n00b

Matt
If I understand correctly .. what you need is a functionaltity to LOG all the messages being transferred on the JMS Server to a data store (RDBMS or File)
If yes, what all JMS Servers provide in case of Durable subscribers is the temp storage of messages in the data store till the message is received by the receiver to ensure gauranteed message delievery.
These messages are deleted from the data store once they are delievered to the subscriber.
In order to achieve Logging like functionality you will need to built a custom application ( a message consumer) which reads messages from the destination (topic/queue) and either writes to the file or using JDBC writes into the database.

How to determine what's using data store temp space?

How can one determine what's using data store temp space? We are interested to know what structures are occupying space in temp space and if possible what pid/process connected to TimesTen created them.
Also, is there a procedure that will work if temp space is full?
Recently one of our data stores ran of space. We we're unable to run commands like "monitor", "select * from monitor", "select count(*) from my_application_table", etc. These commands failed because they required temp space to run and temp space was full. We killed the application processes, this in turned freed up temp space, then we were able to run these queries.
Ideally, we'd like to have a procedure to figure out what's using temp space when temp space is full.
The other thing we could do is periodically monitor temp space prior to it filling to determine what's using temp space.

That was my original thought, but once you click the slider track or thumb, and then enter a value in the text control, the clickTarget on the change event envoked by the change to the bound data (after entering a value in the text control) will be whatever slider element had last been clicked. If you've never clicked the slider, clickTarget=null. But once you've clicked the slider the clickTarget always has a value of "thumb" or "track", regardless of what triggered the change event.
