Need suggestions regarding creation of a UDT

Dear All,
Our client is into Chemicals Trading and deals with Units of Measurements with huge variations.
For example, they stock the items in G but when they purchase, they may purchase in any of Kg,G, MG, micrograms, nanograms or peckograms or pounds based on the their sales requirement. However, their price calculation is based on the price list from the vendor which is again linked with the uit of measurment. A supplier may be supplying 200 peckograms of a chemical based on $100 per 200g. So, we are planning to create 3 UDFs in marketing docs to enter the base price and base units on which the vendor is quoting the price as well as 3 UDFs to enter the required packing size, packing quantity and the packing UoM. Based on the 6 inputs, we want to calculate the quantity, unit price and Total price.
One area of concern for us is that the Standard "Weight UoM" of SAP B1 will not solve the purpose as the base in SAP B1 is always on mg and the system is not calculating correct value when the vase Unit as well as the required Unit are different from mg.
So, if the client wants in nanograms and the suppliers' base unit is g, the conversion is not provided by SAP B1. We have to capture all the conversions between the individual units and get the results. We think it is better to solve the issue through a UDT for Units Of Measurement and define all the linkages between the various UoMs.
I would like to know if there is any workaround for this scenario without creating a UDT and if we need to create a UDT, the structure of the table.
Regards,
Bharath S

Dear Bharath,
In your case, I think creating an UDT might be the most efficient way. The columns in UDT should be as simple as possible such as:
1. BP UoM from BP
2. Standard UoM from Item Master
3. Conversion factor
In this way, you can make sure the conversion is correct. Your UDF in the marketing document could have FMS link to this UDT.
What is your B1 version and PL? 8.8 support multiple UoM better than old version.
Thanks,
Gordon

Need suggestion regarding File compression and splititng

Hi,
I want to split and compress the big files into small chucks. On later any standard zip utility i.e. winzip, 7z etc can merge(extract) all the chunks to generate the original file. I am looking for any java library which provide the split and compression functionality.
As Java also supports in built compression utility. Should I use those library or any other open source is available to do this? I welcome your suggestion regarding how can I start.
Thanks

If you're just looking for something to be used internally, it'd be pretty simple:
1. Open your source InputStream.
2. Create a standard read/write loop to pump the stream.
3. Add a counter that determines how much you've pushed into your current target. After you reach a certain value, close your current target, create a new target stream, and reset the counter.
4. Conclude by closing your source and your current target.
For compression, you can use the built-in GZIPOutputStream or a third-party library of your choice. I usually find GZIP sufficient for my needs.
Of course, if you want the output to be compatible with other programs like 7-Zip, you've got a lot more work on your hands complying with the file format spec. :)

Need suggestion regarding drop RAC database of 11g

Hi All,
I have 11gR2 RAC environment setup. Database required recovery and I have no backup, based on support engineer guidance I restore the database using some hidden parameters though its a corrupted db so I need to rebuild. For rebuild purpose I took expdp of entire database and then drop it. I had drop through "dbca" , db was open and I run "dbca" and select drop database option, at one time it showing me warning/error ORA-01586:database must be mounted EXCLUSIVE and not open for this operation but after that drop was run perfectly.
but when I check the ASM disk status , it still show as it is , I mean no change in their free_space column, I also verified through asmcmd command and all the Datafiles are still there.
I want to cleanup asm disk which are still fillup with dbfs and I thought that would be cleared by dropping database but no my assumption was wrong.
can any one suggest me what to do if I want to make free space in asm disk which was allocated for dbf files?
Thanks in advance.

Need suggestions regarding a system design for incremental load

Hi,
Our client has a set of SQL Server tables which are being fully refreshed daily using views from DB2 source tables. We need to design an approach to load them incrementally.
We have a third party application 'XXX' which will provide us the changed records in the underlying DB2 tables into SQL Server tables daily. Let us call them CDC_<tbl>. This table will have the same schema of source and have a flag to indicate whether
it is an insert, update or delete record. From these CDC tables, we have to do the required transformations and do the insert/update/delete from the target table accordingly.
This approach would work easily for cases where there is only one source table. But when we have multiple tables joined together to load the target table, we are unable to design an approach. If on a particular day, an insert record comes in only one of
the source CDC tables, we will not be getting that row in the target since the other CDC table doesn't have a record for that particular key. We cannot join the SQL Server CDC table with source DB2 table since that will cause performance issues.
Please share your thoughts on how we can design an approach which will work in cases of join, union, group by etc. between source tables. We are open to suggestions on changes in CDC tables also since the third party tool is to be configured as per our design
needs.
Thanks in advance,
KP

If on a particular day, an insert record comes in only one of the source CDC tables, we will not be getting that row in the target since the other CDC table doesn't have a record for that particular key.
If I understand correctly, you extract data using DB2 views (some with joins) and then use third party CDC software to capture all changes made to the underlying DB2 tables. These changes are then applied to a transformed version of data extracted
from the views. If my understanding is correct, why use DB2 views at all? It seems to me the transformation process must have intimate knowledge of the underlying DB2 tables anyway in order to apply the CDC data properly.
Are you saying you are not getting the other CDC table row at all, or is it just that the CDC tables are not transactionally consistent at the time the changes are applied to the target? I think transactional inconsistencies should be addressed by
the third party CDC application. The other alternative as I see it is to query DB2 for a each CDC key to make sure you have the latest data during the transformation process.

Forte Migration - Need Suggestion regarding Forte Migration.

Hi friends,
I need some suggestion in designing GUI.
we have an application designed on mainframes and also in forte. And lots of users life the mainframes, since they have been using for long time and it is easy for data entry and it is faster and by hitting F2/F4 keys the data entry people finish the work fast and they is incentive to do fast and more.
And we have the same application in Forte too, Forte GUI design is also great, it provides lots of data compared to mainframes, but little slower and it cannot be done in the same speed as mainframes.
In such a situation, if you have to migrate what technology would you opt and how to think about converting the console based forte application, which also provides in data entry and provides lots of information.
And it is process oriented, where we could like complete one step before going to other step and also go and modify the data entered in step1. Example, while entering the telephone order, after validating customer details, we would like to provide telephone services. But we should be also able to modify the customer information.
The reason I gave the example before, if you think about using J2EE and provide Web browser interface, which would be best and cut lots of cost and time on deployment (usually in case of Forte console based application), but major draw back would be we cannot control the users activity and you cannot back and forth and update the data. (Think about lot of Tab in Forte application.).
So, the need is for thin client and lots of Tabs and user should be able to go back and forth and real fast application client like mainframes to enter lots of data fast and provider look up for validations.
How would you do migration for such a application ?
1. J2EE, how would you think about providing user interface. (web browser or java console application using swing) ? Did any body of you done using swing.
2. .NET application. (client using ASP.NET with C# for business logic/middle tier)
Please give me some suggestion and how did you migrate under such circumstances.
I know, it is difficult to suggest without seeing the application, but please give me the high level idea. May be you much also faced similar situation.
Thanks in advance.

NET, Swing, Web - all provide options to allow back and forth moving from one tab to the other.
However, No matter how fast the screens are in web, they are a fraction of a second slower when the browser renders the screen.
This is not controlled by programming and it is the browser that takes time. In such scenario, going for Swing may be a better option
All of them support the shortcut keys- Going to Web - you may need to forgo some of the function keys - like f5 for refresh.
You can also introduce numbers in front of values in combos - for easy input of data.
We have experience in migrating thick client to web and thick client to thick client. Please contact me if you need more info.

Need suggestion in creation of domain

Hi,
can we use same domain for common characteristics field or separate domain? (ex: fields with domain value range - Yes or No
Which will be the better approcah?
Regards,
Sri

Hi,
You can use the same domain than creating new domain for the current requirement.
The basic purpose of domain is to define the Data Type and Size of it. Based on the domain we create Data Element, which describes the sematics of the Domain, i.e. the purpose of the Domain assigning to data element to field in table, where you can mention the 4 lables for data element, describes the usage of the data element, assigned to Domain.
So it is advisable to use the exising domain for creating Data elements than creating a new domain with the same data type and size.
Best wishes,

Need suggestion regarding Layout Manager using Swing in Java

I have developed a swing application where i am having problem with selecting the right layout manager.
I am attaching the file where it contains the method for addingComponents to the Content Pane. But, the code that i have written
contains lot of spaces between first panel and second panel and so forth.
Please suggest.
<<Code>>
public void addComponentsToPane(Container contentPane) {
          this.contentPane = contentPane;
//          File Panel
          JPanel jfile1panel = new JPanel(new FlowLayout(FlowLayout.CENTER));
          JPanel jfile2panel = new JPanel(new FlowLayout(FlowLayout.CENTER));
          JPanel jfile3panel = new JPanel(new FlowLayout(FlowLayout.CENTER));
          JLabel jfile1 = new JLabel("Select File:");
          jtfile1 = new JTextField(50);
          jbfile1 = new JButton("Button1");
          jfile1panel.add(jfile1);
          jfile1panel.add(jtfile1);
          jfile1panel.add(jbfile1);

          JButton jbcmd1 = new JButton("Submit");
          JButton jbcmd2 = new JButton("Cancel");
          jbuttonpanel.add(jbcmd1);

          contentPane.add(jfile2panel);
          contentPane.add(jfile3panel);
          contentPane.add(jbuttonpanel);
}

But, the code that i have written contains lot of spaces between first panel and second panel and so forth.use pack(), see if it makes a difference
as you're using FlowLayout, make the frame not resizable

var s = DropDownList1.getDispalyItem(i);
if(s.length ==null)xfa.host.messageBox("the length of the selected value is null");
else xfa.host.messageBox(" Not NULL\n in this case i have written a piece of code to execute");
thing is i am using Live Cycle Designer ES but that length function is not giving the length of the drop down list...
Please suggetst any idea what to do ?????
Thanks in advance.....

The length function works fine you have a typo
incorrect var s = DropDownList1.getDispalyItem(i);
correct var s = DropDownList1.getDisplayItem(i);

300 Users: need suggests...

Hi all! I need to configure an oracle database server (9.2.0.4.0) in order to guarantee that 300 users can connect and use the database in the same time... I need suggests regarding hardware (Cluster? Parallel server?)and software requirements to satisfy this request based on your DBA experience.
Can you help me?
Thank you in advance.
Bye.
Ste.

OLTP is ok, the max workload is 300 users using database at the same time. I think that 9i Enterprise Edition + Real Application Cluster is too expensive... 10g includes Real Application Cluster... Is this right? Then I think the hardware can be like this:
2 server (2 cpu), 2 Gb ram for every server, 1 disk array (4 x 73 Gb) with 2 fiber ports without NAS (for the moment)... Do you know if there is some vendor that sells a system like this for using with Oracle so it is not necessary to buy every device from different vendors and to read long compatibility lists? Do you know any "success case" I can read to find some usefull information regarding the configuration of such a system?

Need suggestion in deletion for five tables at a time

Hi,
I need some suggestion regarding a deletion and i have the following scenario.
tab1 contains 100 items.
for one item tab2..6 tables contain 4000 rows.So the loop will run for each item and will delete 20,000 lines and will do a commit.
Currently for 5,00,000 deletion it is taking 1 hr.All the tables and indexes are analysied.
CURSOR C_CHECK_DELETE_IND
IS
SELECT api.item FROM tab1 api WHERE api.delete_item_ind = 'Y';
type p_item IS TABLE OF tab1.item%type;
act_p_item p_item;
BEGIN
OPEN C_CHECK_DELETE_IND;
LOOP
FETCH C_CHECK_DELETE_IND bulk collect INTO act_p_item limit 5000;
FOR i IN 1..act_p_item.count
LOOP
DELETE FROM tab2 WHERE item = act_p_item(i);
DELETE FROM tab3 WHERE item = act_p_item(i);
DELETE FROM tab4 WHERE item = act_p_item(i);
DELETE FROM tab5 WHERE item = act_p_item(i);
DELETE FROM tab6 WHERE item = act_p_item(i);
COMMIT;
END IF;
END LOOP;
exit when C_CHECK_DELETE_IND%notfound;
END LOOP;
Hope i have explained the scenario.Can you please suggest me the right approach.
Thanks in advance.

drop the loop
DELETE FROM tab2 WHERE item in (SELECT api.item FROM tab1 api WHERE api.delete_item_ind = 'Y' );
DELETE FROM tab3 WHERE item in (SELECT api.item FROM tab1 api WHERE api.delete_item_ind = 'Y' );
DELETE FROM tab4 WHERE item in (SELECT api.item FROM tab1 api WHERE api.delete_item_ind = 'Y' );
DELETE FROM tab5 WHERE item in (SELECT api.item FROM tab1 api WHERE api.delete_item_ind = 'Y' );
DELETE FROM tab6 WHERE item in (SELECT api.item FROM tab1 api WHERE api.delete_item_ind = 'Y' );if you can accomplish the task without looping, by all means do so!
you could also do a bulk delete.
forall j in indices of act_p_item save exceptions
DELETE tab2
WHERE item = act_p_item(j);etc for tab3 to 6
but unless the query SELECT api.item FROM tab1 api WHERE api.delete_item_ind = 'Y' is horrible, I'd stick to the
DELETE FROM tab2 WHERE item in (SELECT api.item FROM tab1 api WHERE api.delete_item_ind = 'Y' ); path

Need suggestion in using Adobe forms

Hi Experts,
I need your suggestion regarding using Adobe document service.
Requiremnt :
I have some paper documents and getting pdf file after scanning it.
I want them to behave like adobe forms, means after getting PDF(after scanning) file i want to update the backend system as in the same way as adobe forms do.
Is it possible???
Thanks in advance for valuable suggestions.

Hi Pankaj,
According to my knowledge there is no option to update the backend system by using the scanned PDF file like adobe forms. It is advisable to design the adobe form by seeing the paper document & updating the backend system.
