ADF : Generating Viewobject table at run time based on Bind Parameter

Hi,
My JDeveloper Version 11.1.1.5,
I am facing one issue. I an not understanding how to deal with it. Its kind of road block for me.
Scenario:
I have a list of value(SOC), Which contains names of projects. Upon selecting one project and clicking on search button, table should be generated dynamically based on a query. To this query I need to pass the selected value from SOC, and should generate the query out put on to the screen, upon clicking on search button.
Could any one please tell me the solution how to implement it?
Please help.
Thanks in Advance,

Hi,
the approach should be
1. on click of search buton get the selected value in managed bean.
2. write a method in am impl to execute the view by setting the where clause with selected value from SOC. the method should accept SOC selected value as parameter.
3. expose the method in clent interface.
4. on click search button method, invoke the am impl method using peration binding.

How to get value in data control at run time based on bind variable in VO

Hi,
we are capturing the value of customer id at run time. we are associating the captured value of customer id to bind variable of the view object.
View object is returning the data of that customer id, this view object is part of the application module ,this application module is exposed as data control,so than we have drag and drop this view object response on the
page from data control.
How ever after assigning the customer id to bind variable but still it is not showing on jsf page,even we refreshed the data control manually with the help of java code so kindly provide some solution for it.

Hi,
If i got your post correctly,you can filter your VO using defining view criteria see following samples

How to insert records dynamically in a table at run time

hi, all
please help me out,
my problum is how can i insert records from on table to another table at run time dynamically. Initally the records are coming from R/3 backend.
regards

Hi,
One way is to first create a Value node (NewNode) with structure binding of that of the model node. Then iterate through the model node, create NewNode elements and set the value from model node elements into it.
IPrivate<view>.I<model node> mele;
IPrivate<view>.I<NewNode> nele;
for(int=0;i<wdContext.node<output>().node<record>().size();i++)
mele = wdContext.node<output>().node<record>().get<record>ElementAt(i);
nele = wdContext.node<NewNode>().create<NewNode>Element();
wdContext.node<NewNode>().addElement(nele);
nele.set<attr>(mele.get<attr>());
Second way is to create that NewNode inside the model node and create a supply function.

Displaying different sheets at run time based on value of the parameter

Hi,
I've a query regarding displaying two different sheets at run time in Oracle discoverer based on the value of the parameter that i give.
I've a parameter Summary_flag.
If the value of the parameter is 'Y',then it should display a sheet,say for example it should display Sheet1.
If the value is 'N',then it should display another sheet, say for example it should display Sheet2.
Is there any way in which i can accomplish this?
I went through the Format and Tools menus but couldnt find anything regarding this aspect.
Can you help me out?
Thanks,

Having a Disco parameter dictate which worksheet is displayed is not an option that is available. There are a few workarounds, though:
1. Have a portlet (or some other web interface) accept your parameters, and then call the appropriate worksheet.
2. Have 2 worksheets, and have it devolve into a training issue (for a summary run this, for all the details run this).
3. Create calculations that will show or hide column data depending on the parameter selected - the columns will still be there, and you can fill them in with blanks, or a message like "N/A for Summary".
4. Create a report that will allow the users to drill between the summary and detail data - I'm not sure whether you could use a parameter to then say whether the report should open up summarized or expanded.

실수로 TABLE을 DELETE 또는 DROP한 경우 복구 방법 (time-based recovery)

제품 : ORACLE SERVER
작성날짜 : 2004-07-29
PURPOSE
사용자의 실수로 중요한 데이타를 delete 하였거나, 테이블을 drop하였을
경우 복구하는 절차를 정리한 자료이다.
Explanation
사용 중인 database 의 archive log mode 여부를 다음과 같이 확인 후
archive log mode인지 아닌지에 따라 복구 방법이 달라진다.
os>svrmgrl
SVRMGR> connect internal;
SVRMGR> archive log list
Database log mode ARCHIVELOG
Automatic archival ENABLED
Archive destination ?/dbs/arch
Oldest online log sequence 2525
Current log sequence 2527
1. Archive mode인 경우 복구 방법
archive log mode로 운영중이면서 full backup및 archive file들이 모두
존재하는 경우 복구가 항상 가능하다.
이때 다시 다음과 같이 두가지의 경우를 구분하여 복구 작업을 수행할 필요가
있으며 아래에 각각의 경우에 대한 절차를 자세히 설명한다.
(1) drop이나 delete한 시점이 얼마 지나지 않았거나, 혹은 필요에 의해
database 전체를 data 손실 이전 시점으로 돌리고자 하는 경우
(2) 손실된 data만을 drop이나 delete이전 상태를 받아내고, 나머지 data는
모두 drop/delete이후 발생한 transaction의 반영분을 유지시키기 위해
현재 시점으로 맞추어햐 하는 경우
1-1 database 전체를 drop이나 delete 이전시점으로 돌리고자 할 때
이러한 경우는 데이타 손실이 발생하기 이전의 datafile들에 대한 backup을
restore한 후 손실 발생 시점 직전까지 time based로 imcomplete recovery를
수행하면 된다.
(1) db를 shutdown시킨 후 현재 상태를 만약의 경우를 대비하여 cold
backup을 받아둔다.
shutdown immediate로 db를 내리고, datafiles, redo log files, control
files 모두 tar등의 명령어를 이용하여 backup을 받아둔다.
이것은 만약의 경우 이전 backup이나 archive file에 문제가 있는 경우,
삭제된 data의 복구가 불가능할 경우 현재 상태로라도 돌리기 위한
것이다.
(2) 데이타를 삭제하기 이전 상태에서 받아둔 datafile full backup을
restore한다.
redo log files과 controlfiles은 현재 것을 그대로 이용하고, 현재
상태의 모든 datafiles을 지우고 데이타가 삭제되기 전에 받아둔
backup datafile을 restore시킨다.
(temp datafile의 경우는 restore시간을 줄이기 위해 restore하지
않아도된다.)
(3) restore한 backup시점 이후의 archive file들을 archive log
destination에 위치시킨다.
full backup 이후의 archive file들을 일부 tape 장비등에 backup을
받아두고 지운 상태라면 그러한 file을을 다시 원래 위치에 restore
하여, full backup받은 시점부터 복구하고자 하는 시점까지의
archive log file들이 모두 log archive destination에 존재하는지
확인한다.
(4) 데이타 삭제 이전 시점까지 time based로 recover를 수행한다.
이때 날짜와 시간 지정은 항상 아래 예와 같은 형식으로 지정한다.
만약 데이타를 삭제한 시간이후로 지정하게 되면 recovery후에도
여전히 data는 지워진 상태로 보여진다.
os>svrmgrl
SVRMGR> connect internal
SVRMGR> startup mount;
SVRMGR> set autorecovery on
SVRMGR> recover database until time '2001-01-30:21:00:00';
SVRMGR> alter database open resetlogs;
(a) 만약 이때, controlfile이 현재것이 존재하지 않아 datafile뿐
아니라, controlfile도 과거것을 사용했다면, recovery command를
다음과 같이 지정하면 된다.
recover database using backup controlfile (아래줄과 이어짐)
until time '2001-01-30:21:00:00';
(b) temp datafile을 restore하지 않은 경우라면 startup mount수행
직후 다음과 같은 문장을 추가하면 된다.
alter databse datafile '/oracle/oradata/temp01.dbf'
offline drop;
/oracle/oradata/temp01.dbf는 temp datafile의 이름을 예로 든
것이다.
(5) 원하는 data가 제대로 조회되는지 확인한다.
1-2. 삭제된 data만을 복구하고 나머지는 현재 상태를 유지하고자 하는 경우
이러한 경우는 데이타가 삭제되기 이전 상태의 backup datafile 중에
SYSTEM, RBS와 삭제된 data가 들어있는 datafile만을 restore시켜 time
based로 recovery하여 db를 open시킨 후 원하는 table만 export를 받아낸다.
그리고 다시 현재 상태의 db에 export받은 내용을 import시키는 것이다.
이때 삭제된 data를 export받기까지의 절차에 대해서 다음과 같이 세가지
경우의 방법을 생각할 수 있다.
(a) 다른 시스템에 backup이나 test용으로 oracle이 설치되어 있는 경우
그 시스템에 backup을 restore하여 해당 table을 export 받는 방법
(b) 같은 시스템에 backup을 restore 하되, db name과 oracle_sid를 다른
이름으로 변경하여 다른 db를 만들어 recovery후 open하여 export받는
방법 <Bulletin:11616 참조>
(c) 현재 db는 cold backup받아 두고, backup을 restore하여 export을
받아내는 방법
여기에서 (a)의 경우는 다른 시스템에 이용하고자 하는 datafile의 oracle
version 이상의 oracle software가 이미 설치되어 있어야 한다.
(b)의 경우는 현재 상태의 cold backup을 받았다가 export받은 후 다시
현재 상태를 restore할 필요는 없애주지만, 대신 SYSTEM, RBS, user
datafile 만큼의 disk space가 추가로 필요하며, 새로운 db를 추가로
구성하는 것이므로 init.ora file 구성 등의 작업이 필요하다.
이것에 관한 자세한 절차는 <Bulletin:11616>을 참조하도록 한다.
이 자료에서는 이중 (c)에 대한 것만을 자세히 설명한다.
(1) 현재의 모든 datafiles과 redo log files, datafiles을 다음과 같이
신중히 cold backup을 받아두도록 한다.
이것은 이후에 삭제한 data를 복구하여 export를 받은 후에 다시 현재
상태의 db로 되돌아오기 위한 것이다.
단 이 때 tar 등을 이용하여 cold backup하는 대신에 disk 상에 cold
backup을 받아 시간을 절약할 수 있다. disk로의 backup이 가능한
이유는 export를 위한 time based recovery를 수행하기 위해 필요한
datafile이 SYSTEM, RBS, 삭제된 data를 포함한 user datafile
정도이기 때문이다.
os>svrmgrl
SVRMGR> connect internal
SVRMGR> shutdown immediate;
SVRMGR> exit
os>cp /oracle/oradata/*.ctl /oracle/backup/*.ctl
os>cp /oracle/oradata/redo*.log /oracle/backup/redo*.log
os>mv /oracle/oradata/system01.dbf /oracle/backup/system01.bak
os>mv /oracle/oradata/rbs01.dbf /oracle/backup/rbs01.bak
os>mv /oracle/oradata/tools01.dbf /oracle/backup/tools01.bak
redo log file이나 controlfile의 경우는 time based recovery시에도
필요하므로 cp를 받아두고, datafile의 경우는 mv를 이용하도록 한다.
위의 예에 제시된 file이름들은 해당 환경에 맞게 변경되어야 하며,
tar를 이용하여 tape에 옮겨도 관계는 없으나, 단 cold backup에
해당하는 모든 datafiles, redo log files, control files를 받아두어야
한다.
(2) 삭제한 data가 존재할 당시에 받아둔 backup에서 SYSTEM datafile, RBS
datafile, 그리고 삭제한 table이 들어있는 datafile만을 restore한다.
redo log files과 controlfiles은 현재 것을 그대로 이용한다.
(3) restore한 backup시점 이후의 archive file들을 archive log
destination에 위치시킨다.
full backup 이후의 archive file들을 일부 tape 장비 등에 backup을
받아두고 지운 상태라면 그러한 file을을 다시 원래 위치에 restore
하여, full backup받은 시점부터 복구하고자 하는 시점까지의
archive log file들이 모두 log archive destination에 존재하는지
확인한다.
(4) restore하지 않을 datafile, 즉 SYSTEM, RBS, 삭제된 data를 포함하
는 user datafile을 제외한 모든 datafile은 모두 offline drop시키
고, 데이타 삭제 이전 시점까지 time based로 recover를 수행한다.
이때 날짜와 시간 지정은 항상 아래 예와 같은 형식으로 지정한다.
만약 데이타를 삭제한 시간이후로 지정하게 되면 recovery후에도
여전히 data는 지워진 상태로 보여진다.
os>svrmgrl
SVRMGR> connect internal
SVRMGR> startup mount;
SVRMGR> alter database datafile '/oracle/oradata/temp01.dbf'
offline drop; (윗줄과 이어짐)
SVRMGR> alter database datafile '/oracle/oradata/userdata05.dbf'
offline drop; (윗줄과 이어짐)
... 이와 같이 resotre하지 않은 datafile을 모두 offline drop시킨다.
SVRMGR> set autorecovery on
SVRMGR> recover database until time '2001-01-30:21:00:00';
SVRMGR> alter database open resetlogs;
만약 이때, controlfile이 현재것이 존재하지 않아 datafile뿐 아니라,
controlfile도 과거것을 사용했다면, recovery command를 다음과 같이
지정하면 된다.
SVRMGR>recover database using backup controlfile until time
'2001-01-30:21:00:00'; (윗줄과 이어짐)
(5) 원하는 data가 제대로 조회되는지 확인한 후 필요한 table을 export한다.
예를 들어 scott user의 dept table을 복구하고자 한것이었다면 다음과
같이 export를 받는다.
os>exp scott/tiger file=dept.dmp tables=dept log=deptlog1
(6) time based로 recovery후 open한 db는 shutdown하여 없애고 (1)번에서
받아둔 현재 상태의 backup을 restore한다.
shutdown은 immediate나 abort 모두 가능하며, shutdown후 restore한
SYSTEM, RBS, user datafile모두 삭제하고, 사용하던 controlfiles,
redo log files도 모두 삭제한다.
그리고 (1)에서 mv나 cp로 (혹은 tar로) 옮겨놓은 모든 datafiles,
controlfiles, redo log files를 원래의 directory와 이름으로
위치시킨다. SYSTEM, RBS, user datafile도 반드시 (1)번 상태의
현재 상태 backup을 restore하여야 한다.
(7) db를 startup시킨 후 (5)에서 받은 export내용을 import시킨다.
os>imp scott/tiger file=dept.dmp tables=dept ignore=y commit=y
log=deptlog2 (윗줄과 이어짐)
(8) 원하는 data가 제대로 조회되는지 확인한다.
2. No archive mode 로 운영할 경우 복구 방법
archive mode 로 운영하지 않았을 경우에는, 삭제한 data를 export 받아
두었거나, 혹은 data가 삭제 전 받아둔 cold backup이 존재하는 경우
복구가 가능하다.
(1) export가 존재하는 경우
다음과 같이 import한다. scott user의 dept가 삭제된 경우를 예로 들었다.
os>imp scott/tiger file=dept.dmp tables=dept ignore=y commit=y log=log1
(2) cold backup이 존재하는 경우
다른 시스템에 사용가능한 oracle engine이 설치되어 있다면, 그곳을
이용하거나, 혹은 현재 database를 backup받아둔후 현재 시스템에
restore하여 export를 받아낼 수 있다.
(1) 현재의 모든 datafiles과 redo log files, datafiles을 다음과 같이
신중히 cold backup을 받아두도록 한다.
이것은 이후에 삭제한 data를 복구하여 export를 받은 후에 다시 현재
상태의 db로 되돌아오기 위한 것이다.

os>mv /oracle/oradata/rbs01.dbf /oracle/backup/rbs01.bak
os>mv /oracle/oradata/tools01.dbf /oracle/backup/tools01.bak
위의 예에 제시된 file이름들은 해당 환경에 맞게 변경되어야 하며,
tar를 이용하여 tape에 옮겨도 관계는 없으나, 단 cold backup에
해당하는 모든 datafiles, redo log files, control files를 받아두어야
한다.
(2) 삭제한 data가 존재할 당시에 받아둔 backup에서 SYSTEM datafile,
RBS datafile, 그리고 삭제한 table이 들어있는 datafile만을
restore한다.
backup당시의 redo log files과 controlfiles도 restore하여야 한다.
(3) restore하지 datafile, 즉 SYSTEM, RBS, 삭제된 data를 포함하는 user
datafile을 제외한 모든 datafile은 모두 offline drop시키고,
database를 open시킨다.
os>svrmgrl
SVRMGR> connect internal
SVRMGR> startup mount;
SVRMGR> alter database datafile '/oracle/oradata/temp01.dbf'
offline drop; (윗줄과 이어짐)
SVRMGR> alter database datafile '/oracle/oradata/userdata05.dbf'
offline drop; (윗줄과 이어짐)
... 이와 같이 resotre하지 않은 datafile을 모두 offline drop시킨다.
SVRMGR> alter database open;
(4) 원하는 data가 제대로 조회되는지 확인한 후 필요한 table을 export
한다.
예를 들어 scott user의 dept table을 복구하고자 한 것이었다면
다음과 같이 export를 받는다.
os>exp scott/tiger file=dept.dmp tables=dept log=deptlog1
(5) exprot받아낸 database는 shutdown하여 없애고 (1)번에서 받아둔
현재 상태의 backup을 restore한다.

Calculation of KFs at query run-time based on Characteritics Drill-down

Hello All,
I have an Important Issue which I need to solve but got stuck.
The report requirement is that we need calculate the KF values based on the drill-down selection in the report at run-time.
Say for eg: if the user is drilling-down the report by customer, plant or company code or any thing else other than material group...we need to calculate / Include KF values for only Materail Group = "A" and if we are at the materail group level we need to calculate all the material groups which includes A, B, T and so on.
Please suggest what are the avialable options for me like using virtual key figures. please provide me with some sample codes.
your help will be highly appricated.

How to pass a run time value as a parameter to a webdynpro iview

Hi,
we have a webdynpro which we can call with passing a run time value in this form:
https://xxx.yyy.zzz/sap/bc/webdynpro/sap/zfkq_inv_1?WI_ID=000000004332&sap-client=700&sap-language=EN&sap-wd-sapgui=X
This link will be sent to many users but the WI_ID will change every time.
It works fine but now we want to implement this webdynpro in our portal. The user shall get a link like this
https://xxx.yyy.zzz/irj/portal/webdynpro-test?wi_id=000000004332. With this link he will navigate directly to the webdnypro (quicklink-function).
The problem is that i don't know how to transfer the parameter WI_ID in the url to the webdynpro.
It's no problem to fix the WI_ID in the application parameter properties but this is not what we want.
Is it possible to transfer the url parameter to the application parameters of the webdynpro iview ?
Thanks in advance.
Best Regards
Mirko Berscheidt

Hi Mirko,
The first thought I had is if your scenario makes sense at all. Because you might send out the links, but probably the iView will also be accessible via navigation, and in that case this additional parameter won't be there!?! (And if the iView is not accessible by navigation, then why going the way via the portal and not the direct way to the application like with your first link given?!).
Anyhow, I think this should be possible by using the AppIntegrator, see The customer exit of the Application Integrator
For an example about how to add individual values to users which you then can add to the URL see this discussion: App Integrator, and custom URL parameters using Customer Exits - this might be a possibility that each user can call the "same" iView but in fact the app integrator then would be fired with different URL parameters (per user).
Hope it helps

Bind a new view object to same adf table at run time

Hello,
I have an adf table, that changes based on the type of data the user selects. For example, lets say we have a page that consists of type drop down box at the top and an ADF table at the bottom, which lists data based on the type that is selected from the drop down box. For example, lets say, I have the types (Cars, Planes, and Trains).
Let's further say we have a view object for cars, one for Planes and one for Trains. Each VO has its own specific set of attributes associated with them, which in should be reflected in the adf table that's on the screen.
So for example, I select Train..
My table should contain the columns, num cabs, train type, year built
For plane, the columns might be Num engines, plane manufacturer, size(ie. 747, 727, etc), year built
Some type of thing with Cars , cylinders, color, model, year, etc.
Is there a way to tell my adf table to use a specific view object(ie. Plane, train, or car) at runtime?

You can try implementing this with dynamic components, e.g. dynamic table
>
ADF Dynamic and ADF Read-Only Dynamic Table: Allows you to create a
table when the attributes returned and displayed are determined dynamically
at runtime. This component is helpful when the attributes for the
corresponding object are not known until runtime, or you do not wish to
hardcode the column names in the JSF page. For more information about
working with dynamic components, see Section 26.7, "Using a Dynamic Form
to Determine Data to Display at Runtime."
>
Or you use dynamic regions and swithc the region containing the table depending on the selectOneChice. Check http://docs.oracle.com/cd/E24382_01/web.1112/e16182/taskflows_regions.htm and https://blogs.oracle.com/shay/entry/adf_dynamic_regions_switching_just

Based on the input parameter can OBIEE select table at run time

For e.g if we select monthly from the drop down then the same report must fetch data from monthly report
and at the same time if a persons selects daily then the same reprot must fetch data from daily table.

Let's assign a presentation variable to the drop down values i.e. var_Status
Now in functionality of the column that you want to change it's functionality dynamically depends on your selection... write this formula
case when '@{var_Status}' = 'Daily' then Table1.Col1 else Table2.col2 end
Because of this.. we can't have dynamic column heading for this column.
One more approach is: Same Presentation variable but with Sectional Guided navigation properties.
see here: http://oraclebizint.wordpress.com/2008/01/17/oracle-bi-101332-selecting-reports-from-dashboard-prompts-and-guided-navigation-sections/
You have to develop 2 reports for this..

ORA-00903: Invalid table name - running Set based mapping

Hello,
Using OWB 10.2.04.36 and have created a mapping which reads data from Non-Oracle, ODBC source table, actually a worksheet in an Excel workbook which has been defined/set up using the Heterogeneous Service components.
I can view the data in the worksheet using the Design Center, Data Object Editor, Data Viewer tab so I know the data is accessible.
The mapping is performing a Loading Type: INSERT/UPDATE into a View which has an INSTEAD OF INSERT OR UPDATE OR DELETE ON view.
The mapping validates okay and is deployed successfully.
Yet when it is run in "Set based" Operating Mode from Control Center Manager the Execution Results show an "ORA-00903: Invalid table name" error is raised.
You cannot run the mapping in any Row based operating mode as Row based running fails with "ORA:22816: Unsupported feature with RETURNING clause" due to the generated code for the INSERT/UPDATE of the view using a RETURNING clause which is actioned on an INSTEAD OF trigger.
Looking at the generated package code I can strip out the SELECT statement from the MERGE statement for the alias "MERGE_SUBQUERY" and it runs and displays the expected result, however when the complete MERGE statement is taken and run I get the same ORA-00903 error that was reported in Control Center Manager.
Any ideas what the problem could be? I have another mapping that reads from the same source Excel workbook/worksheet and INSERT/UPDATE into a table without an INSTEAD OF trigger, this mapping deploys, runs successfully so the issue seems to be with the INSERT/UPDATE into the view. The views are what we require to be populated.
Thanks.

Hi,
But changing V_EMP_DEPT to EMP is not INSERTING/UPDATING to the view V_EMP_DEPT, what you propose is INSERTING/UPDATING into the table EMP. The code was only an example showing that the MERGE does not work when INSERTING/UPDATING into a view based on joining tables. For example say you wanted to INSERT/UPDATE the DNAME of V_EMP_DEPT then the MERGE statement generated by OWB PL/SQL mapping would use the code structure/template:-
MERGE INTO "V_EMP_DEPT" "V_EMP_DEPT"
   USING (SELECT 5369 "EMPNO",
                 'SMITH' "ENAME",
                 'CLERK' "JOB",
                 7902 "MGR",
                 To_Date('17/12/1980','DD/MM/YYYY') "HIREDATE",
                 800 "SAL",
                 'New Dept Name" "DNAME"
          FROM   Dual,
                 "DEPT" "DEPT"
          WHERE ("DEPT"."DEPTNO" = 20)) "MERGE_SUBQUERY"
   ON (    "V_EMP_DEPT"."EMPNO" = "MERGE_SUBQUERY"."EMPNO")
   WHEN NOT MATCHED THEN
      INSERT("V_EMP_DEPT"."EMPNO",
             "V_EMP_DEPT"."ENAME",
             "V_EMP_DEPT"."JOB",
             "V_EMP_DEPT"."MGR",
             "V_EMP_DEPT"."HIREDATE",
             "V_EMP_DEPT"."SAL",
             "V_EMP_DEPT"."DNAME")
      VALUES("MERGE_SUBQUERY"."EMPNO",
             "MERGE_SUBQUERY"."ENAME",
             "MERGE_SUBQUERY"."JOB",
             "MERGE_SUBQUERY"."MGR",
             "MERGE_SUBQUERY"."HIREDATE",
             "MERGE_SUBQUERY"."SAL",
             "MERGE_SUBQUERY"."DNAME")
   WHEN MATCHED THEN
      UPDATE
         SET "ENAME" = "MERGE_SUBQUERY"."ENAME",
             "JOB" = "MERGE_SUBQUERY"."JOB",
             "MGR" = "MERGE_SUBQUERY"."MGR",
             "HIREDATE" = "MERGE_SUBQUERY"."HIREDATE",
             "SAL" = "MERGE_SUBQUERY"."SAL",
             "DNAME" = "MERGE_SUBQUERY"."DNAME";
{code}
This was only an example my target view has a lot more columns being MERGE'd into the view and joined tables.
Cheers,
Phil
