How to cache the data of a view?

Hi all,
I have problem on saving the data of a view object.
Basiclly, I have a View1 which takes long time to generate from database, then I will do some query(max, group by, etc) over View1 to generate View2 multiple times based on different parameter.
I want to avoid executing View1 multiple times because it is very costly. Is there any way to achieve it?
I try Method1: put this View1 in database as a VIEW, and Method 2: generate an ADF View Object for View1. Both have to re-generate View 1 whenever I generate View2...
Thanks!

Thanks for the reply, Timo.
I am afraid that it is not possible to optimize the query. It takes long time because the query is based on the sale history of the whole year.
One way to achieve my goal is to create a table in database, insert the result of view1 into the table, then query over this table instead of View1.
But I am thinking if ADF has this functionality or not. I just found a view object API called setQueryMode, don't know if it helps or not.

How to transfer the data in navigation view?

Hi Gurus,
I have done the webdynpro development which has the floor plan manager road map.
So after user enter the value in the UI then can review the data by pressing review button and data will get transfer to next screen where user will able to see the data that they have entered in the first screen .
I my requirement I got three views edit view /Old field selection view /Field selection view.
I have created the Webdynpro application which will freeze the value of duration as half of the work schedule allocated to the employee once they choose half day as a type of absence.
In my application Duration field is getting populated with the half of the workschedule (say 4 hours (8full work schedule/2))allocated to the employee .
But once I pressed the Review button duration field again reffering the full work schedule (say 8 hours) in the next screen.
How to map my changes with next screen as well.
Thanks in Advance,
Dharani

Hi Gurus,
My application is based on Floor Plan manager which has the road map( review data,send data and confirm data)
requirement is what ever the changes i made it in the intial screen should pass on the same value to the next screen which is review screen
and then it has to pass to Send Data screen..........
All the above said review data send data and confirm data are buttons which is available in the screen once I deployed the webdynpro application.
But In the layout there is no buttons defined in the view? iam really confused?
Please help me this is very urgent requirement............

How to compare the data in a view with data present in a master data?

Hi All,
We have loaded some data into a Master Data Object (YMETADATA) in Development system.
Now, the same data can be present in a view RSDVCHA.
Our aim is to write a ABAP program, which would read a record from RSDVCHA and look into Master Data records and show whether it is present in the master data or not?
Has anyone written such type of code earlier, If so, please do help me out in writing this code?
Thanks in advance,
Anjum.

Hello Anjum,
It looks that the view is based on the master data table itself and view doesn't contain data and is a logical representation of the underlying database tables.
Moreover the view RSDVCHA is used for viewing the characteristics, basic chars and local properties.
Are you storing similar values in YMETADATA?

How can I Cache the data I'm reading from a collection of text files in a directory using a TreeMap?

How can I Cache the data I'm reading from a collection of text files in a directory using a TreeMap? Currently my program reads the data from several text files in a directory and the saves that information in a text file called output.txt. I would like to cache this data in order to use it later. How can I do this using the TreeMap Class? These are the keys,values: TreeMap The data I'd like to Cache is (date from the file, time of the file, current time).
import java.io.*;
public class CacheData {
public static void main(String[] args) throws IOException {
String target_dir = "C:\\Files";
String output = "C:\\Files\output.txt";
File dir = new File(target_dir);
File[] files = dir.listFiles();
// open the Printwriter before your loop
PrintWriter outputStream = new PrintWriter(output);
for (File textfiles : files) {
if (textfiles.isFile() && textfiles.getName().endsWith(".txt")) {
BufferedReader inputStream = null;
// close the outputstream after the loop
outputStream.close();
try {
inputStream = new BufferedReader(new FileReader(textfiles));
String line;
while ((line = inputStream.readLine()) != null) {
System.out.println(line);
// Write Content
outputStream.println(line);

I don't understand your question.
If you don't know how to use TreeMap why do you think a TreeMap is the correct solution for what you want to do?
If you are just asking how to use TreeMap then there are PLENTY of tutorials on the internet and the Java API provides the methods that area available.
TreeMap (Java Platform SE 7 )
Are you sure you want a map and not a tree instead?

How to open the Data Perspective function of Smart View in EAS?

How to open the Data Perspective function of Smart View in EAS?
I use my Smart View to connect one ASO cube, and I found the button of Data Perspective is grey. It's not available.
In Smart View Users' Guide, it says:
Note: Data perspective may not be enabled in your Smart View system. Your options for data perspective are enabled and configured by the administrator in Oracle Essbase Administration Services.
But I could not find how to configure the this option in EAS.
Does anyone know about this?

I have already turned on the varying attributes function, but the data perspective button is still grey, not available.

How to maintain the data in the view cluster

we are doing upgrade, we have one view cluster app_log in this object scwb
and subobjects is swtlo1,02,03 like i have some subobjects in 4.6c we transported the view cluster to ecc6.0 in ecc 6.0 i have object scwb but subobjects doesn't exist how to maintain the subobjects in view cluster.

Definition
A view cluster is a group of maintenance dialogs which are collected in one maintenance unit for business or technical reasons. They allow related data in more than one table/view to be maintained consistently.
Use
Whereas only 1:1 relationships can be processed in maintenance views (except for language-dependent texts), key extensions and relationships of cardinality N:M can also be handled in view clusters. Maintenance dialogs with no key, or partial key-dependence, can also be combined into view clusters.
Grouping dialogs into one maintenance unit has the following advantages for data maintenance:
Navigation: A view cluster contains convenient standard navigation between the individual maintenance dialogs. This simplifies the maintenance of the data in a view cluster.
Consistency: The view cluster ensures data consistency when deleting, copying, saving, retrieving and manually transporting data. For example when an entry in a higher-level view is deleted, , it automatically ensures that all dependent entries in lower-level views are also deleted.
You can first split tables with a lot of fields into various views and then collect them into a view cluster.
Use tabs to format very wide tables with a lot of fields.
Structure
Navigation in a view cluster is usually based on the hierarchy of the tables/views on which the dialogs are based. A view cluster usually consists of one or more root dialogs and the at most 14 maintenance dialogs which depend on them. A view at a lower level has one or more additional fields in its key compared its higher-level view. Each data record at the higher level has several dependent data records below it.
Each maintenance dialog is an independent unit consisting of an overview screen or an overview and a detail screen, depending on the dialog type. As well as the data to be maintained, the overview screen contains a navigation area, in which you can go to higher or lower level maintenance dialogs.
One-level maintenance dialogs only contain one screen, the list screen, in which all existing data records are displayed in a table. In a two-level maintenance dialog, double-clicking on a data record in the list screen takes you to the detail screen, which displays all the fields in the selected data record.
Generate a maintenance dialog for each view before you call the cluster maintenance (SM34). When you generate the maintenance dialog, flag the key fields which are identical in the view and its higher-level in the cluster, with the maintenance attribute S. The system fills the key fields when you go from the upper to the lower level, with the values of the data record selected in the upper level. Go to the transaction SE54 to define a view cluster.

Server Admin - How current is the data?

Good afternoon.
When I view the DHCP data in Server Admin, how current is the data? When I close down workstations and logon others, the data displayed, even after multiple refreshes, does not change. A quit & relaunch doesn't update the data either.
Can I rely on Server Admin to provide a current, accurate view?
Brian Bowell

I'm not sure of the frequency at which Server Admin re-polls the data, but nothing is cached so at the very least each time you connect to a server you're seeing data that's valid up until then.
However, in the case of DHCP you need to consider lease duration.
If your lease is set to something like 3 days then any given client will remain in the DHCP leases list for that long.
In other words, assuming you have one DHCP client on your network and that machine boots on Monday Afternoon, then that machine will appear in the DHCP leases list until at least some time on Thursday afternoon. The number of leases will not decrease when the machine shuts down on Tuesday, nor increase if that machine comes back online before the original lease expiration (it will just be re-issued the same DHCP lease/IP address/etc.). Therefore your lease counter will remain at 1 even when the machine is offline.
Is it possible that accounts for what you're experiencing? The number of leases does not reflect the number of active DHCP clients on your network, just the number that have been active within the last (lease duration) hours.

How to pass the data from a input table to RFC data service?

Hi,
I am doing a prototype with VC, I'm wondering how VC pass the data from a table view to a backend data service? For example, I have one RFC in the backend system with a tabel type importing parameter, now I want to pass all the data from an input table view to the RFC, I guess it's possible but I don't know how to do it.
I try to create some events between the input table and data service, but seems there is no a system event can export the whole table to the backend data service.
Thanks for your answer.

Thanks for your answer, I tried the solution 2, I create "Submit" button, and ser the mapping scope to be "All data rows", it only works when I select at least one row, otherwise the data would not be passed.
Another question is I have serveral imported table parameter, for each table I have one "submit" event, I want these tables to be submitted at the same time, but if I click the submit button in one table toolbar, I can only submit the table data which has a submit button clicked, for other tables, the data is not passed, how can I achieve it?
Thanks.

How to check the data in a temporary table

Hi,
A procedure inserting data into a temporary table , data exists in the table now. so, how to see the data from the temporary table. Is it possible to see from the sqlplus by selecting, right now i'm not getting any data. .thanks Bcj.

If you are referring to Global Temporary Tables, then the only way to see the contents of the table are to select from the table while connected to the same session that inserted the data into the GTT.
Please note however that there is not a 1 to 1 correspondence between sessions and users (shcemas). A user may be connected to 1 or more sessions, but it is only the session that inserted the records that will be able to view the records.

How to save the data for multiple sittings

Hello All
i have one sign up form. user enter only 4 to 5 fields & he may not fill the the manditory field & he left. but data base don’t give the error to him. but next day he will come at then he want to complet his sign up i.e. when he commit the all detail that time all validation will hapen.
for that i use one table without constrain to store the temarory detail.& use other table (with constrains) for final submition.
1) i creat the view n entity for temparory table
2) & also i create views n entity for Final table
n i create one methos in AmImple file in that file I create one method & expose to client n I drag n drop this method as a ADF Button & in that method I write the following logic
1) taking the data from one view (from temporary table) & setting the value to other view(Final table).
using this i set the value from tempary to final table...
but when user left the manditory field then it allow to submit the data in temparory field but when i copy that data to final table(with constrain) n user submit the data then validation happn i.e. "this fild is mandatory".when i click this error message it goes to first screen.
I try to implement this functionality…but its not working.
can u plz suggest other way to implement this functionality in ADF using jdevloper11g
Thanks in Advance

User,
I don't get it :-(
How do you find out if a user comes back or is completely new? You have to have some information about the user to remember him. At least this information has to be mandatory (even for the temporary table).
Let's assume you have figured out that the user has been on your page before:
load his credentials from the temporary table to the form, let him fill in the rest and if he hit save save it in the final table.

How to Audit the data displayed within a Webi report

Hi All,
We have BOBJ XI R2 SP4 installed on our server.
One of the requirements is to audit the data the user has viewed through Canned reports and also Adhoc reports created in Webi.
I understand that we can audit what reports are accessed by the user, but not sure how to audit the data within the report. Could someone please let me know if auditing data can be acheived form SDK ? If so how ?
Thanks,
Sireesha

Pablo,
The following should get you started;
This is a report to pull Universe Name, Report Name, Action Time (last refreshed), Action Duration (execution time), User Name and Object Name (universe objects used in reports).
The Result Objects are as follows:
Object Name from Actions/Action Details
Action Time from Actions
Action Duration from Actions
Action Type from Actions
Action Type Detail from Actions (detail object associated with Action Type)
User Name from Actions
Document Name from Actions/Document
Universe Name from Actions/Action Details
The Query Filters are as follows:
Action Time between Day1 And Day2
Note: The Query Filter is necessary (obviously) only to restrict the size of the query. I wouldn't run this query without a filter on demand. Depending on the size of your deployment, you might want to restrict the query initially to a specific universe/list of universes while testing.
At the report level, I moved Universe Name and Document Name in to (nested) sections.
i.e.
Section on: Universe Name
Section on: Document Name
Table
Another option would be to retrieve this information from the CMS tables using WID Scanner [here|http://www.forumtopics.com/busobj/viewtopic.php?t=80856]
The last option would be to use the Report Engine SDK (for Webi) to write a program extract this information from the CMS tables and pass it to another table. WID scanner (above) does effectively the same thing, passes the info to an MS Access table (if I remember correctly..I may be wrong. I have'nt used it since it last tried to create a report to extract all used objects.)
Best,

How to retrive the data from a sqlite file(.db3) in windows phone 8.1(runtime)

hey guys
i installed the sqlite and sqlite-net as requested in other answers i found, changed to x86, and add the .db3 file in my project.
but the problem is how to retrive the data that already in the file( i am not creating any table or data in the app, just read)
all the answer i found is to create a table first and then read the table, i tried to skip the step of creating a table, and read from the table directly, but failed with " no such table", by the way, i set the property of the .db3 file as "content",
"copy if newer"
can anyone please help? i appreciate that !

Hello,
From your description, you want to read data from available sqlite file. When you add the sqlite file into your project, you need to change the sqlite file build action to content. After deploying to device, the sqlite file is located in installation folder,
you need to copy that file into storage folder before reading data. Please try the following code snippets.
private async void Button_Click_9(object sender, RoutedEventArgs e)
//check if file exists in storage folder, and then copy to local storage
bool flag = await FileExistsAsync("Data.db3");
if (!flag)
var folder = await Package.Current.InstalledLocation.GetFileAsync("Data.db3");
await folder.CopyAsync(Windows.Storage.ApplicationData.Current.LocalFolder);
// open sqlite and read data
public async Task<bool> FileExistsAsync(string fileName)
try
await Windows.Storage.ApplicationData.Current.LocalFolder.GetFileAsync(fileName);
return true;
catch (FileNotFoundException)
return false;

Is it possible to retrieve the data from maintainance view?

Hi experts,
Am facing one problem.
Is it possible to retrieve the data from Maintainance View ,If yes how?
IF it is not possible then Y?
While am trying to retrieve data from maintainance view it's showing message like
"it is not a database view or table".
Can u pls give me ans.
Thanks&Regards,
Arun.

Hi Arun,
It is not possible to retrieve the data from Maintenance view. Maintenance View is different and Database View is different.
Maintenance view : Maintenance view permits you to maintain the data of an application object together.The data is automatically distributed in the underlying database tables.
A standardized table maintenance transaction is provided (SM30), permitting you to maintain the data from the base tables of a maintenance view together.
In other words, Maintenance views enable a business-oriented approach to looking at data, while at the same time, making it possible to maintain the data involved. Data from several tables can be summarized in a maintenance view and maintained collectively via this view. That is, the data is entered via the view and then distributed to the underlying tables by the system.
Database View: Data about an application object is often distributed on several database tables. A database view provides an application-specific view on such distributed data.A database view is automatically created in the underlying database when it is activated.Database views implement an inner join.If the database view only contains a single table, the maintenance status can be used to determine if data records can also be inserted with the view. If the database view contains more than one table, you can only read the data.
Database views should be created if want to select logically connected data from different tables simultaneously. Selection with a database view is generally faster than access to individual tables. When selecting with views, you should also ensure that there are suitable indexes on the tables contained in the view.
Hope this helps.
Please reward if useful.
