Sequence generation(urgent)

Hi
im new to jdev..I would like to set sequence generation for table fields.Im using JSp as my client and populating fields in the jsp screen.pls let me know is there any thing to set on wizard or any help in tutorial..thnks..

I'm assuming that you've added your code segment to EmpImpl.java.
The first parameter to SequenceImpl() should be the name of a database sequence, not the name of a table column.
Once you've changed that, if you still get the same error, you need to check whether EmpImpl.java has a method called setId(), since this is what your error is complaining about. Your entity should contain accessor (getter and setter) methods by default. If your entity doesn't have these methods, then edit the entity, select the Java tab in the Entity Object Wizard, and check "accessor methods" for the entity object class.
Lastly, I recommend testing your business components in the business component browser (aka the tester). This is a way of making sure your business logic works before you try to run your client.

Single image sequence generation. ?

Hello, ..
Essentially, I'm looking to find the best solution, to the idea of building sequences where and with using - importing, different sequencial, single images.
— To be clearer perhaps, I'm a Weather student / enthusiast, and this would be toward generating a sequence / different sequences .. of hourly weather-satellite obtained images.
To this point, or up until very recently, and in fact for several years previous, I have - in fact, been able to do this fairly simply, with using an older version of QuickTime (older logo, I think that main version offered still, through "Tiger".) and, with once I've dropped a first or more initial image more in particular, into the application, then merely dragging and dropping whichever others into its main viewer-window, checking save, and naming the file.
— Perhaps, unorthodox. But, it's worked just fine for the idea.
— And, of course, this idea can't be used with the newer version/s of QuickTime.
"very recently": .... Today, and with having been using this method of "simple sequence" generation, together with older version of QuickTime, on my relatively new "iMac", and running Snow Leopard, Mac OS X v. 10.6.8 - all up to date, ....
.. I've found that I'm no longer able to access the older version of the application. (I think this advent, might be related to a "MacKeeper" clean-up that I did recently. ....)
— In fact, the main reason that I can't say more exactly, which version it is - or was, in fact.
Beyond this question more general, I'm thinking — (Something, I think that I'd read at one point in the past.) — that I can in fact do what I've suggested above, with / within QuickTime Pro.
Hope this is clear - at all.
Any help. ?
Appreciate your response and time.

Opening an "image sequence" (folder of sequentially named same dimension files) is a feature found only in QuickTime Player Pro.
Beginning with Snow Leopard the OS includes QuickTime Player X (in Lion it is 10.1) in the Applications folder and QuickTime 7.6.6 is moved to the Utilities folder.
QuickTime X has its own feature set but can't be upgraded to "Pro".

Sequence generation in Oracle RAC env. (Cached, non-ordered)

Env: Oracle Env. 11G, Transaction Java Application
How does CACHED, non-ordered sequence behave (for PK generation), here is the scenario,
Cache size =10
Node 1 Active - Records created 1,2,3 (3 records total in table)
Node Changes - 2 is Active - Records created 11,12,13, 14 (7 records total in table)
Node Changes - 1 is Active - Records created 21, 22 (or are sequences going to be 4, 5) (9 records total in table)
Node Changes - 2 is Active - No new record added (9 records total in table)
Node Changes - 1 is Active - 2 more Records created (9 recor11s total in table) - Is it going to be 23, 24 OR or is it going to be 6,7 OR or is it going to be 31, 32 (9 records total in table)
Please help with accurate generated seq numbers (PKs) for 9 records.
Also, What happens to PK numbers at:
* shutdown
* hotbackup
* mirroring whole schema or database to another separate db using storage mirroring
* mirroring whole schema or database to another separate db using datapump
How about using cached, ordered sequences to start with and change to no-order if needed for performance reasons

A necessary problem solving skill in the Oracle environment is the ability to experiment. A couple of minutes constructing a simple test is better than hours of speculation:
jw1> create sequence s1;
Sequence created.
jw1> select s1.nextval from dual;
NEXTVAL
        1
jw1> /
NEXTVAL
        2
jw1> conn sys/oracle@jw2 as sysdba

jw2> select s1.nextval from dual;

Sequence Generation on Oracle Client

Hi...
We have to create sequences on the oc4j client with the format <mobileuser name><date stamp><sequence number>.How do we get the mobileuser name from the mobile client authentication.Can u please tell us the API to login the mobile client and how it can be passed on to include in the sequence.
Thanks in Advance....

You need to place that code where ever you are creating your user session object. I don't know the architecture you are using so I really can't tell you exactly where to place it.
http://download-uk.oracle.com/docs/cd/B19188_01/doc/B15920/nvappdev.htm
Here is what the documentation has on the subject:
<blockquote>
7.2.4.3.2 Web-to-Go User Context
Web-to-Go creates a user context (or user profile) for every user who logs in to Web-to-Go. Web applications always run within the user's specific context. Servlets, which are always part of an application, can use the user context (in which it is running) to access the services provided by Web-to-Go. The user context can then be used to obtain the following information.
Name of the user
Mode the user is running in (online or offline)
Application that a user is accessing
The database connection
Roles that the user has for this application
Name or value pairs stored in the registry for the user
Servlets can access the user profile through the standard named java.security.Principal obtained through the getUserPrincipal method of the javax.servlet.http.HttpServletRequest class.
This object can also be obtained from the HttpSession object. For example,
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException{
// Retrieve the database connection from the User Profile,
// which can be accessed from the HttpRequest
HttpSession session = request.getSession(true);
OraUserProfile profile = (OraUserProfile)session.getAttribute("x-mobileserver-user");
7.2.4.3.3 Database Connectivity in Java Code
Servlets can obtain a connection to the Oracle database, using the following statement.
HttpSession sess = request.getSession();
WTGUser user = (WTGUser)sess.getAttribute("x-mobileserver-user");
Connection conn = user.getConnection() ;

Sequence generation issue

Hi , I am working in Healthcare industry . we have a claim and payment matching process . Every day 1.5 million payments get matched with 70 million claims and the matched payments are stores in some output table . After matching, an oracle seqence number is generated for each matched record and that is the primary key for the output table.
Match query will be like this,.
Select seqeunce1.nextval,a.column1,a.column2,b.coulmn1,b.column2 from claim_table a, payment_table b
where a.column3=b.column3
We are facing some seqence problem here. some sequence are missed during the first day and the missed sequnces are getting generated in the second day.
Sequence Query:
CREATE SEQUENCE ERA_CLAIM_MATCH_S
START WITH 1
MAXVALUE 999999999999999999999999999
MINVALUE 1
NOCYCLE
CACHE 500
NOORDER;
Example to demonstrated the problem:
Day 1(15th July) : sequence generated from 1 to 1000000 (some sequence are missed in between)
Day2 (16th July) : sequence generated from 2500 to 2000000 (some missed sequence in day 1 are generated here)
Our database in in RAC system.

Hemant K Chitale wrote:
I think that the question is : If the highest value generated on Day 1 was 1000000, how could a value of 2500 be generated on Day 2 ?
Shouldn't happen if the Sequence is a NOCYCLE.Hemant, but that is possible if Day 1's processing used the sequence on RAC instance 1 - whereas on Day 2, RAC instance 2 (with unused cached sequences from yesterday) is used.
E.g.

Sequence Generation

Hi,
I want to generate a sequence of numbers daily remebering where the last sequence number was from the day before.
Is there a straight solution in lieu of using a JDBC solution.
Can somebody help on this and give some clarity.

Hi ,
I guess by having a counter object ,storing the current sequence in it,and using persistence u can acheive the same.
But i wud have gone for a database storage.

Next Sequence number - Urgent help

I have to pass in a sequence number in my method.
The sequence number is the order an attribute should appear in relative to other attributes in this Address object.
Can anyone help in how i am to do this.....i am confused!!
Ta
Sammy

Sorry if i confused you.
I have an object which contains attributes that are dislayed. On the UI the user can add an attribute to that object.
Eg: Address object, it has attributes, line1, line2, town, postcode. The user can add an attribute called county to the object.
My address object contains a parmeter called sequecene. So when the attribte is added, it should be added to the next sequence- so for teh example above it would be sequence no 5. So i think i need to work out the maximum sequence number of the contained attributes in the object.......but not sure how to do this.
Any help would be appreicated.
Thanks

DB Adapter Multi Table sequence generation through a procedure call

Sequence generation automatically

Hello,
I don't if I'm wrong or I'm unable to find how: I'd like to generate sequences for primary keys in a database. I can generate the sequences but I do not find the way to trigger it automatically.
Does anyone know if Designer generates the whole pack: sequence and trigger or do I have to write the trigger manually and associate it with the sequence?
Thank you for help.

Hi,
Once you have generated the table and the sequence, generate the Table API for that table with the "Generate Table API Triggers" checkbox selected.
This will create and generate the triggers.
And if you are generating Form modules whose blocks are based on that table, your next step is to generate the Module Component API.

Wrong MRP generation-Urgent

Issue: - Wrong MRP generation.
We use to receive the 6 month rolling plan from the customer in the form of Excel sheet. Then our marketing team feed the day wise plan in SAP under Sales Operation plan under TCode(MC82).
The main issue is some time by mistake marketing team uploads the full month requirement in one day only. When MRP runs then the material requirement planning gets affected majorly.
To bring the ownership in marketing department, we want to put a workflow system on TCode(MC82).
Eg:-
SOP Upload-- SOP Reviewed--
SOP
Approved----
MRP Run.
Please suggest, How can we implement such system on the T Code MC82.
Regards
Vivek K. Sharma

Uploading some values in MC82 will only have impact on MRP when it is transferred to DM eg: by MC75
So before you transfer why not review the details in MC75 by doing an on-line transfer instead of invisible or background schedule?
If you wish to manage this as a workflow, then you will need to get in touch with a workflow consultant or maybe the workflow forum would be able to provide guidance for you.

Sequence generation problem

Incorrect. They are generated properly since they are always unique.

Change in Request type and different sequences generation for Req. Type

Dear All,
We have the following requisition types in the Requisition Form:
1. Purchase Requisition
2. Internal Requisition
We would like to divide the Internal Requisition to:
Internal Requisition from Branches and
Internal Requisition from Departments/Sections
I found that these values are available in FND_LOOKUPS table.
Is it possible for us to make this change, through the Application Developer..?
If the above change is possible, then based on the requisition type selection, it should generate a different sequence number.
Is this possible without customization..?
Please update...
Many thanks in advance..
Edited by: santark on Jan 20, 2010 4:03 AM

Is it possible for us to make this change, through the Application Developer..?I dont know if one can change or not but I would suggest not to try and do internal changes
If the above change is possible, then based on the requisition type selection, it should generate a different sequence number.
what you can do is open a DFF at header level,make a number series auto generate which could be a context sensitive DFF ..depending on what type of requisiton is being made, Internal or standard..if internal, u can classify the numbering series too..this type of customization is achievable
Hope this helps
Please mark the thread as useful or answered if it is

from the Oracle docs:
"ORA-01002: fetch out of sequence
Cause: In a host language program, a FETCH call was issued out of sequence. A successful parse-and-execute call must be issued before a fetch. This can occur if an attempt was made to FETCH from an active set after all records have been fetched. This may be caused by fetching from a SELECT FOR UPDATE cursor after a commit. A PL/SQL cursor loop implicitly does fetches and may also cause this error.
Action: Parse and execute a SQL statement before attempting to fetch the data. "
taken from:
http://technet.oracle.com/doc/server.804/a58312/newch221.htm#16189
Solution:
when you use "for update" in your select statement you must set the connection's auto commit to false--> Connection.setAutoCommit(false);

Parent/Child BC4J Entity Object Sequence # Generation

If anyone can help us in this we greatly appreciate it. We are using DBSequence data type to poplulate the parent entity with the sequence #; however, we need to populate the child entity with the same sequence #.
We have a DB Trigger for every insert of the parent's key and it's working great but what do we need to do for populating the child record.
Is there a way to get the sequence # as a part of the this code for the child entity object.
protected void create(AttributeList attributeList)
super.create(attributeList);
SequenceImpl mySeq = new SequenceImpl("MY_SEQ",getDBTransaction());
setMyObjectId(mySeq.getSequenceNumber());
Thank you,
Kamran

Well,
I still can't insert the parent's primary key as a forign key automatically. Like in the Dept/Emp situation, I need to setup the supporting Impl files so it would insert the Dept No automatically as a part of the Employee creation.
New info : Here is a sample of what I am trying to accomplish. Sorry I could
have been more clear:
I am sending you my Workspace using Scott's table Dept and Emp. In my JSP file,
The user needs to input the Department information and some of the Employee
info, but the same deptno generated for the Dept record needs to be populated
for the Employee at the time of submit.
Please let me know if you need anything else.
Thank you,
Kamran

Serial/Sequence Generation in INFORMIX

Hello Friends,
How can a sequence number be generated in INFORMIX? Its known that there is SERIAL
column... But, is there any way to get this done as below:
func()
id=get_next_id();
EXEC SQL insert into table1 values (id, ...);
get_next_id()
EXEC SQL select .......I don't know what should come here???
return..
This is possible in Oracle as u can read the next value from a sequence. Does
Informix also provide some such functionality??
Thanks for ur time and answers.
Best Regards
MS

As far as I know, you can't. The serial is a property of the table. The new value
is created when you insert a row in the table.
(In fact you can force a value in the column, as long as it does not violate the
UNIQUEness constraint).
The engine will always try to take the next value, except when that is already
present. On startup it takes the highest value in the column + 1.
The serial is returned in the error structure (forgot the name for the moment)
after the insert, so you can use it for other updates.
The mechanism is less flexible than Oracle's, but automatic (as no separate select
is necessary), KISS like.

Hello Friends,
How can a sequence number be generated in INFORMIX? Its known that there
is SERIAL
column... But, is there any way to get this done as below:
func()
id=get_next_id();
EXEC SQL insert into table1 values (id, ...);
get_next_id()
EXEC SQL select .......I don't know what should come here???
return..
This is possible in Oracle as u can read the next value from a sequence.
Does
Informix also provide some such functionality??
Thanks for ur time and answers.
Best Regards
MS
