When to refresh Servlet data from Data Base

Hello all,
I have a servlet that retrive few hundreds thousands records from data base table.
The data in data base table being updated once or twice in every week.
Since same servlet instance serve all users, that access the servlet many times a day.
I would like to avoid retriving the data from data base on each servlet access.
and make the users use same data already retrieved and kept in servlet members.
First, what is the best way to avoid data retrive from data base on each servlet access?
and how could I have some kind of trigger that will refresh servlet data from data base every few days?
Thanks in advance for every idea.

Thanks Saish for your reply.
I'm not using DAO in my application but retrive the data from BI data base using a web service. response time querying the BI data base is not quick enuogh.
Since, I wouldn't want to query the BI server on each servlet access.
Because the data I retrived at the begining using the web service contains all required data for all servlet requests, I thought to store the data (~200K rows) once in the servlet which will be using for all requests.
Why not store the results locally in your own database after you fetch them?
This still leave me with the questions: in which event should I query the BI data, and also when or in which event should I update the data again from BI server?
Query at startup, an user demand, when data becomes stale. It depends on your requirements.

Util class to extract Data from Data base Table.

Is there any Util class to extract all records from Data base table into DAT file.For example(get all amployees from EMPLOYEE table in to employee.DAT )

What is a DAT file?
Anyway, this can be achieved using a shot of JDBC [1] and some business logic [2] to populate/group/concat the data together in a DAT format and writing [3] it to that DAT file.

How do I import individual frames from iMovie into iPhoto?

How do I import individual frames from iMovie into iPhoto? Or how do I export individual frames from iMovie into iPhoto? My final goal is to have a DVD of individual photos from a video I recently shot. Thanks

Here is one way to do it, although you will see there could be variations.
1) Open iMovie
2) Start a new project - name it Stills for iPhoto (or a name of your choice)
3) Go to your EVENT. Find the spot with the cursor that you want a photo of. Right-click (or control-click if you don't have a mouse) and select ADD STILL FRAME TO PROJECT.
4) The photo should be in the Project called Stills for iPhoto.
5) Right-click (control-click) on the photo and select REVEAL IN FINDER.
6)When the finder window opens, right-click and select COPY. Go to your Desktop or a folder of your choice and right-click PASTE
7) Drag the photo from your Desktop to iPhoto

Importing music, artwork and data base from external hard drive

I purchased a MacBook to use primarily as a music server. I have an external hard drive with over 300GB of music files ripped from CDs in Apple Lossless with a computer using Windows XP. I also have another external hard drive formatted for the Mac. My goal is to attach both drives to the MacBook via USB and transfer the music files, album art, and iTunes data base from the Windows system hard drive to the new Mac formatted hard drive. Then I am going to reformat the Windows system hard drive to the Mac format and use it as a back up for the other hard drive. Has anyone ever done something similar? If so, I would appreciate some guidance. If possible, I want to do the above so that the file names and artwork from the Windows itunes system do not get changed or left out when making the transfer to the Mac system. All music files will still be in ALAC. Thanks to all for your help.

Lots of programs out there from which to choose. In the meantime, don't access the drive.

Call function from data base with clob input parameter.

Hello,
In this project I use Jdev 11g.
I call function from database.
create or replace function get_fa_list (
p_fa_id_list in clob
return sys_refcursor
is
vCursor sys_refcursor;
begin
put_msg ('begin');
if p_fa_id_list is null then
put_msg ('CLOB is null!');
else
put_msg ('size CLOB: ' || dbms_lob.getlength (p_fa_id_list));
end if;
put_msg ('Save');
open vCursor for
select rownum as id, s.*
from (
select f.latitude, f.longitude, count (distinct f.res_id) as res_count, count (*) as fa_count, 16711680 as color, res_concat_distinct (f.res_id) as station_list
from mv_frequency_assignment f, table (SplitClob (p_fa_id_list, ',')) l
where f.ext_system = 'BI' and
f.ext_sys_id = l.column_value
group by f.latitude, f.longitude
) s;
put_msg ('Open and End');
return vCursor;
end get_fa_list;
I use TopLink in ejb.
i use follow code for call function and get result.
public List<TmpResPoints> findAllPointsBI(String p_id){
UnitOfWork uow = getSessionFactory().acquireUnitOfWork();
uow.beginEarlyTransaction();
StoredFunctionCall call = new StoredFunctionCall();
call.setProcedureName("get_fa_list");
call.useUnnamedCursorOutputAsResultSet();
ClobDomain c = new ClobDomain(p_id);
//System.out.println(c.toString());
call.addNamedArgumentValue("p_fa_id_list", c);
ReadAllQuery query = new ReadAllQuery();
query.setReferenceClass(TmpResPoints.class);
query.setCall(call);
List<TmpResPoints> result = (List<TmpResPoints>)uow.executeQuery(query);
uow.commit();
uow.release();
return result;
But size parameter "p_fa_id_list" is 0. (geting from temp table in Data base). this code in function >>
if p_fa_id_list is null then
put_msg ('CLOB is null!');
else
put_msg ('size CLOB: ' || dbms_lob.getlength (p_fa_id_list));
end if;)
How I can call this function from dataBase and get result?
thx,
Demka.

What is the SQL generated?
The argument should just be the Clob value (a String) not the domain object.
Also try addNamedArgument, and then pass the named argument to the query.

Performance problem in select data from data base

hello all,
could you please suggest me which select statement is good for fetch data form data base if data base contain more than 10 lac records.
i am using SELECT PACKAGE SIZE n statement, but it's taking lot of time .
with best regards
srinivas rathod

Hi Srinivas,
if you have huge data and selecting ,you could decrease little bit time if you use better techniques.
I do not think SELECT PACKAGE SIZE will give good performance
see the below examples :
ABAP Code Samples for Simple Performance Tuning Techniques
1. Query including select and sorting functionality
tables: mara, mast.
    data: begin of itab_new occurs 0,
             matnr like mara-matnr,
             ernam like mara-ernam,
             mtart like mara-mtart,
             matkl like mara-matkl,
             werks like mast-werks,
           aenam like mast-aenam,
stlal like mast-stlal,
     end of itab_new.
select fmatnr fernam fmtart fmatkl gwerks gaenam g~stlal
into table itab_new from mara as f inner join mast as g on
fmatnr = gmatnr where gstlal = '01' order by fernam.
Code B
tables: mara, mast.
data: begin of itab_new occurs 0,
      matnr like mara-matnr,
      ernam like mara-ernam,
      mtart like mara-mtart,
      matkl like mara-matkl,
      werks like mast-werks,
      aenam like mast-aenam,
      stlal like mast-stlal,
end of itab_new.
select fmatnr fernam fmtart fmatkl gwerks gaenam g~stlal
into table itab_new from mara as f inner join mast as g on f~matnr =
gmatnr where gstlal = '01'.
sort itab_new by ernam.
Both the above codes essentially do the same function, but the execution time for code B is considerably lesser than that of Code A. Reason: The Order by clause associated with a select statement increases the execution time of the statement, so it is profitable to sort the internal table once after selecting the data.
2. Performance Improvement Due to Identical Statements Execution Plan
Consider the below queries and their levels of efficiencies is saving the execution
tables: mara, mast.
data: begin of itab_new occurs 0,
      matnr like mara-matnr,
      ernam like mara-ernam,
      mtart like mara-mtart,
      matkl like mara-matkl,
      werks like mast-werks,
      aenam like mast-aenam,
      stlal like mast-stlal,
end of itab_new.
select fmatnr fernam fmtart fmatkl gwerks gaenam g~stlal
into table itab_new from mara as f inner join mast as g on f~matnr =
gmatnr where gstlal = '01' .
sort itab_new.
select fmatnr fernam
fmtart fmatkl gwerks gaenam g~stlal
into table itab_new from mara as
f inner join mast as g on f~matnr =
gmatnr where gstlal
= '01' .
Code D (Identical Select Statements)
tables: mara, mast.
data: begin of itab_new occurs 0,
      matnr like mara-matnr,
      ernam like mara-ernam,
      mtart like mara-mtart,
      matkl like mara-matkl,
      werks like mast-werks,
      aenam like mast-aenam,
      stlal like mast-stlal,
end of itab_new.
select fmatnr fernam fmtart fmatkl gwerks gaenam g~stlal
into table itab_new from mara as f inner join mast as g on f~matnr =
gmatnr where gstlal = '01' .
sort itab_new.
select fmatnr fernam fmtart fmatkl gwerks gaenam g~stlal
into table itab_new from mara as f inner join mast as g on f~matnr =
gmatnr where gstlal = '01' .
Both the above codes essentially do the same function, but the execution time for code B is considerably lesser than that of Code A. Reason: Each SQL statement during the process of execution is converted into a series of database operation phases. In the second phase of conversion (Prepare phase) an execution plan is determined for the current SQL statement and it is stored, if in the program any identical select statement is used, then the same execution plan is reused to save time. So retain the structure of the select statement as the same when it is used more than once in the program.
3. Reducing Parse Time Using Aliasing
A statement which does not have a cached execution plan should be parsed before execution; this parsing phase is a highly time and resource consuming, so parsing time for any sql query must include an alias name in it for the following reason.
1.     Providing the alias name will enable the query engine to resolve the tables to which the specified fields belong to.
2.     Providing a short alias name, (a single character alias name) is more efficient that providing a big alias name.
Code E
select jmatnr jernam jmtart jmatkl
gwerks gaenam g~stlal into table itab_new from mara as
j inner join mast as g on jmatnr = gmatnr where
            g~stlal = '01' .
In the above code the alias name used is j .
4. Performance Tuning Using Order by Clause
If in a SQL query you are going to read a particular database record based on some key values mentioned in the select statement, then the read query can be very well optimized by ordering the fields in the same order in which we are going to read them in the read query.
Code F
tables: mara, mast.
data: begin of itab_new occurs 0,
      matnr like mara-matnr,
      ernam like mara-ernam,
      mtart like mara-mtart,
      matkl like mara-matkl,
      end of itab_new.
select MATNR ERNAM MTART MATKL from mara into table itab_new where
MTART = 'HAWA' ORDER BY MATNR ERNAM MTART MATKL.
read table itab_new with key MATNR = 'PAINT1'   ERNAM = 'RAMANUM'
MTART = 'HAWA'   MATKL = 'OFFICE'.
Code G
tables: mara, mast.
data: begin of itab_new occurs 0,
      matnr like mara-matnr,
      ernam like mara-ernam,
      mtart like mara-mtart,
      matkl like mara-matkl,
      end of itab_new.
select MATNR ERNAM MTART MATKL from mara into table itab_new where
MTART = 'HAWA' ORDER BY ERNAM MATKL MATNR MTART.
read table itab_new with key MATNR = 'PAINT1'   ERNAM = 'RAMANUM'
MTART = 'HAWA'   MATKL = 'OFFICE'.
In the above code F, the read statement following the select statement is having the order of the keys as MATNR, ERNAM, MTART, MATKL. So it is less time intensive if the internal table is ordered in the same order as that of the keys in the read statement.
5. Performance Tuning Using Binary Search
A very simple but useful method of fine tuning performance of a read statement is using Binary search addition to it. If the internal table consists of more than 20 entries then the traditional linear search method proves to be more time intensive.
Code H
select * from mara into corresponding fields of table intab.
sort intab.
read table intab with key matnr = '11530' binary search.
Code I
select * from mara into corresponding fields of table intab.
sort intab.
read table intab with key matnr = '11530'.

Delete From Data Base

Dear Experts
How we can delete the Planned order & also Production order from the DATA base sothat they will not display again.
i have already setup the deletion Flag on all production order And also planned order were also deleted from the Delete button.
so i need to delete it from the Data Base sothat it will not appear in the data.
Rgds
Pankaj Agarwal

Dear,
What is error you are getting?
See also SAP notes 540834
CO78 is a one stop transaction for production order setting deletion flag, deletion indicator, archiving and finally deleting. Please follow these step,
Generally we schedule the following programs in background in the sequence below,
1. PPARCHP1 for Setting Deletion Flag
2. PPARCHP1 for Setting Deletion Indicator (Once set cannot be revoked- so care should be taken in selection of orders)
3. PPARCHA1 for archiving the production order with Deletion Indicator active. Basis should set the database/storage space for archiving/storing the records.
4. PPARCHD1 for Deleting the records from SAP database.

Migrate an schema from oracle 8i to 11g

Hello,
I am struggling to find all the requirement to upgrade one schema running on oracle db 8i installed on an sparc server non-global solaris 8 zone to a oracle 11g running on solaris 10 x86 non-global zone.
there are changes in architecture.
what I know is:
export using exp utiliy from oracle 8i
import in oracle 11g using exp utility of 11g if still available.
I only need to migrate two schemas respectively of 1gb and 2gb
here are the schemas and the sizes:
Total
Schema Schema Name Size (Mb)
CLAIMS 2851.07031
ARCCLAIMS 1290.9375
can you someone tell me what is the best way to perform this.. this is what I think i should do.
I have to set the character set NLS_Lang of the source db both in source and target machine. both server do not have the same character set. oracle 8i has WE8ISO8859P1 and oracle 11g has WE8MSWIN1252
then perform execute the catsql.exp script
perform the exp
exp sys/******* owner=CLAIMS file=CLAIMS.dmp
for the imp do i have to create the user or it will be created automatically should I create the timespaces amd user manually?
what would be the command to be used to import?
thank you.

How to display and edit the clob datatype column from Data base

Hi ,
I have a requiremsnt as below
1) One Table having some columns with CLOB data type along with varchar columns
2) need to display the data from DB in search screen and need to be edited clob column in edit screen
I created EO and VO with that Table and how to display the clob value into the input box for editing.
using Jdev 11.1.1.5.0 version.
Can you please help on this.
THanks & REgards,
Madhu

Hi,
If you are using an inputText component to display a Character Large Object (CLOB), then you will need to create a custom converter that converts the CLOB to a String.
For custom convertor refer below link,
http://docs.oracle.com/cd/E2438201/web.1112/e16181/af_validate.htm#BABGIEDH

UNIQUE Problem in pulling DATA from DATA base table to internal table

Dear Experts,
I am new to ABAP. I have a very basic question but looks a quite puzzling one to me. Hemnce I am posting it here.
I am facing an unique problem in pulling data from database table and populating that data into internal table for further use.
The data in the database table "Zlt_mita" with fields M1 (Employee Name, Type: Char20) and M2 (Employee Code, Type Char7) are:
Plz refer the screenshot in the attached file:
My Code:
1) When I try to pull data from Dbase table by taking M2 as parameter.
     This code is succcessful and I am able to populate data in internal table it_dat.
TYPES: Begin Of ty_DAT,
                 M1   TYPE Zlt_mita-M1,
                 M2   TYPE ZLT_mita-M2,
             END OF ty_DAT.
DATA: it_dat        TYPE STANDARD TABLE OF ty_dat with header line,
          wa_dat      TYPE   ty_dat.
PARAMETERS: p_mitar    TYPE Zlt_Mita-M2.
SELECT           M1
                       M2
        FROM     ZLt_mita
        INTO       TABLE it_dat
        Where     M2 = p_mitar.
Loop at it_dat into wa_dat.
   WRITE:/2 wa_dat-M1,
              10 wa_dat-M2.
ENDLOOP.
2) When I try to pull data from Dbase table by taking M1 as parameter.
     This code is NOT succcessful and I am NOT able to populate data in internal table it_dat.
TYPES: Begin Of ty_DAT,
                 M1   TYPE Zlt_mita-M1,
                 M2   TYPE ZLT_mita-M2,
             END OF ty_DAT.
DATA: it_dat        TYPE STANDARD TABLE OF ty_dat with header line,
           wa_dat      TYPE   ty_dat.
PARAMETERS:    P_Mita    TYPE   ZLT_Mita-M1.
SELECT           M1
                       M2
        FROM     ZLt_mita
        INTO       TABLE it_dat
        Where     M1 = P_Mita.
Loop at it_dat into wa_dat.
   WRITE:/2 wa_dat-M1,
             10 wa_dat-M2.
ENDLOOP.
Why is this happening when both M1 and M2 are Type Character fields.
Looking forward for your replies.
Regards
Chandan Kumar

Hi Chandan ,
Database fetch is case sensitive ,So u need to give exact format in where condition.
Make your parameter and database in same case so that you need not worry about case sensitivity .
Check the lowecase check box in the domain .
Then declare your parameter
PARAMETERS:
P_Mita
TYPE   ZLT_Mita-M1 LOWER CASE .
You can do the vice versa also by unchecking lowercase and giving Upper case instead of lower in parameter declartion .

ALV GRID OOPS: Output refresh from data base

Hi All,
I have below issue.
I display ALV and select a row and click a button to transfer stock for the selected row.
I used BAPI_GOODSMOVEMENT_CREATE to update and after material document got posted, the row should update its stock information.
Is there any solution without reselecting all data?
Regards,
Pratyusha

You will have to select the latest data from the DB, so prepare the 'ITAB' containing your data again (should work if you change only for this row only).
I believe after the BAPI commit call, refresh your ALV using REFRESH_TABLE_DISPLAY, modify the itab with new data and then call SET_TABLE_FOR_FIRST_DISPLAY.
