Forms6i Problem with datatype
Hi,
i've a table with 4 columns which have different datatypes.
My insert form only shows one of them whichever is the right datatype.
The problem is when the user inserts into a integer field letters and he press the button cancel (there are two buttons ok and cancel) i want that the form disappear and
nothing happens but i always get the error message:
FRM-50016 admissable signs are 1,2,3...
How can i handle this?
Thanks for help.
With best regards
Nicole
Hi,
it doesn't work.
Sorry i have told you wrong, i don't want to leave the whole form , i want to leave the window without error message.
Now i always must delete the letters and then i come out of it, but i want that he do nothing when i press the button cancel.
Thanks for help.
With best regards
Nicole

Forms6i - problem with jre.exe
I have a problem with installation of Forms6i.
I have processor Celeron 1700 and Windows XP.
I have installed Forms6i, but when I try to run Oracle Net8 Easy Config
there is an error with jre.exe and program close.
I have installed Patch 10 but the error is continually present.
I don't know what I can do.
I know, that it is probably the processor's fault.
It's very important to me.
If somebody knows what to do, please mail me: [email protected]Forms6i is not yet certified on XP. See Re: required query for this requirement

Problems with datatypes while callling MS-SQL stored procedure
Hi
We have a stored procedure in MS-SQL server ( Sql Server 2000 ) that we are invoking from XI 3. ( SP18) using a receiver adapter communication channel . One of the parameters of the stored procedure has a decimal data type . In XI design time - in the mapping - to the stored procedure data type - we have specified 'DECIMAL' as the type for attribute of the import parameter of the stored procedure . My source field in the mapping is of type string.
This is resulting in an error on the Adapter Engine - 'Cannot convert datetime to decimal' ( as seen in RWB ) -
Are we right in specifying DECIMAL as the type in the XI mapping to the type attribute of the stored procedure parameter ?
Any pointers, thoughts shared on this is appreciated. Correct answers will be rewarded.Sai and Others
The problem was that - among the big number of stored procedure parameters - that were to be passed from XI to the stored procedure call - we had to disable a few of the fields inbetween - inorder to test the stored procedure call with the main parameters that were to be passed.
This disabling of the selective fields inbetween - messed up the order inbetween the XI stored procedure datatype and the actual stored procedure definition. We learnt a lesson not to disable fields within a stored procedure - now the call to the stored procedure is going through without using any conversion function for the string to decimal - as long as a decimal value keeps appearing at the source field always ( which is the case here )
Thanks for your pointers, thoughts and suggestions... -
Programming problems with INT / FLOAT
I got a problem with datatypes float and int.
I'm just developing a c-program on HP-UX with the gcc-compiler. 'cause i have not ever been done an ORACLE-access before, i has started with the "cdemo2.c" - example from the oracle-demo-dircetory in version 8.0.4.
in the DB there's a column with NUMBER-TYPE, but when i call the oci-function (or what ever it is) "odescr()", the variable "scale" (which is supposed to differentiate between FLOAT_TYPE and INT_TYPE) always is set to "0". this variable should be set to anything else but "0" if a FLOAT_TYPE is detected, but it isn't.
what I do wrong ???
How can I know the exact datatype, when a NUMBER_TYPE in the DB appears ???
if there is a better way to realize an oracle-access in C, please don't wait to tell it to me
many thanks
nullYou basically got it. Another approach is to always work on the rightmost digit; that way you'll always be dividing, mod'ing, or multiplying by 10.
You don't need to know the length of anything to use a for loop. Remember that a for loop has 4 parts: the initialization, the conditional, the "update", and the body. (There are probably more correct names for these that I can't recall right now.) The conditional and the update tend to be length checks and increments only because for loops are commonly used over arrays or strings, but they don't have to be.
Another hint: how do you know when you're done pulling the digits out of the source number? What is the value of the source number when you're done? -
Problems with Pro*C and the double datatype
Hi!
I'm working with Pro*C 8.1.7 on HPUX 11.0, but I've a problem
with the datatype double.
On runtime, I got a Bus Error (core dumped) when try assign a
double bind_variable (Pro*C) with a double variable (ANSI_C)
For example:
typedef struct xxxx
float item_ANSI_C;
double variable_ANSI_C;
} xxxx;
void procedure_name()
EXEC SQL BEGIN DECLARE SECTION;
xxxx *POINTER;
double double_bind_variable_PRO*C;
EXEC SQL END DECLARE SECTION;
EXEC SQL WHENEVER SQLERROR DO (...);
for (i = 0; ; i++)
EXEC SQL WHENEVER NOT FOUND DO break;
EXEC SQL FETCH cursor INTO (...),
:double_bind_variable_PRO*C,
POINTER.item_ANSI_C = other_bind_variable_PRO*C;
(***)POINTER[i].variable_ANSI_C = double_bind_variable_PRO*C;
(***): In this point the program throw BusError(core dumped).
However, the float datatype does not.
------- End Example -------------
Somebody have any solution for this problem? Please.
Thanks, in advance.
Alex.Hi Franz,
Though it's a bit late, I'll leave this trace for those who follow.
IRecordset also has Fields->Item.
What might work is:
IField * field;
field = rec->Fields->Item(0);
field->get_Value(0); (or something similar for your environment).
I couldn't find any documentation either.
The C++ examples are not overwhelming, are they?
Worse, they are not supported. Otherwise SBO-support is very hilfsbereit.
Cheers,

Problem with XSU and DataSources with nested cursors?
We are having a problem with the xsu libraries (OracleXMLQuery) using nested cursor syntax. The class returns nicely nested xml document when a database connection is established in the traditional/legacy manner of "class.forName(); DriverManager.registerDriver();" .
However, when using a DataSouce object within a J2EE container, we get an xml document back that only represents the main level of the resultset with datatypes + memory addresses for the cursor fields (instead of the expected nested xml elements).
Any thoughts?
BTW, we are using the iPlanet Application Server with an Oracle 9i database.
for instance:
SELECT a, b, CURSOR(select m, n, o
from table2
where table1.x = table2.y),
d, e, f
FROM table1
WHERE table1.name = 'Matt'Somebody please answer this question?

Problem with sqlldr and commit
Hi,
i have a problem with sqlldr and commit.
I have a simple table with one colum [ col_id number(6) not null ]. The column "col_id" is primary key in the table. I have one file with 100.000 records ( number from 0 to 99.999 ).
I want load the file in the table with sqlldr ( sql*loader ) but i want commit only if all records are loaded. If one record is discarded i want discarded all record of file.
The proble is that in coventional path the commit is on 64 row but if i want the same records of file isn't possible and in direct path sqlldr disable primary key :(
There are a solutions?
Thanks

Problem with JPA Implementations and SQL BIGINT in primary keys
I have a general Question about the mapping of the SQL datatype BIGINT. I discovered, that there are some different behaviour depending on the JPA implementation. I tested with TopLink Essentials (working) and with Hibernate (not working).
Here is the case:
Table definition:
/*==============================================================*/
/* Table: CmdQueueIn */
/*==============================================================*/
create table MTRACKER.CmdQueueIn
CmdQueueInId bigint not null global autoincrement,
Type int,
Cmd varchar(2048),
CmdState int,
MLUser bigint not null,
ExecutionTime timestamp,
FinishTime timestamp,
ExecutionServer varchar(64),
ScheduleString varchar(64),
RetryCount int,
ResultMessage varchar(256),
RecordState int not null default 1,
CDate timestamp not null default current timestamp,
MDate timestamp not null default current timestamp,
constraint PK_CMDQUEUEIN primary key (CmdQueueInId)
The java class for this table has the following annotation for the primary key field:
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name = "CmdQueueInId", nullable = false)
private BigInteger cmdQueueInId;
When using hibernate 3.2.1 as JPA provider I get the following exception:

This means, that their ID generator does not support java.math.BigInteger as datatype.
But the code works if I take TopLink essentials as JPA Provider.
Looking at the spec shows the following:
In chapter 2.1.4 "If generated primary keys are used, only integral types will be portable." Integral datatypes are byte, short, int, long and char. This would mean, that the Hibernate implementation fits the spec but there seem to be a problem in general with BIGINT datatypes.
I use a SYBASE database. There it is possible to declare a UNSIGNED BIGINT. The range of numbers is therefore 0 - 2^64 - 1. Since in Java a long is always signed it would mean its range is from -2^63 -1 to 2^63 -1. So a mapping of BIGINT to java.lang.long could result in an overflow.
The interesting thing is, that I used NetBeans to reverse engineer an existing database schema. It generated for all Primary Keys of Type BIGINT automatically a java.math.BigInteger. But for other fields (not being keys) it mapped BIGINTs to java.lang.long.
It looks like there are some problems with either the spec itself or the implementation of it. While TopLink seems to handle the problem correctly, Hibernate doesn't. But Hibernate seems to fulfill the spec.
Is anybody familiar with the Spec reading this and can elaborate a little about this situation?
Many thanks for your input and feedback.
TomNot sure if I clearly understand your issue, would be good if you can explain it a bit more clearly.

Hello
I'm pretty new to Java, and sometimes all those objects, instances, classes, data types etc confuse me. I'm having some kind of a problem with ArrayLists (tried with vectors too, didn't work) . I'm writing a program which takes float numbers from user input and does stuff to them. No syntax error in my code, but I get a java.lang.ClassCastException when I run it.
I insert stuff to the ArrayList like this:
luku.add(new Float(syotettyLuku));no problem
I'm trying to access information from the list like this inside a while loop
float lukui = new Float((String)luku.get(i)) .floatValue();but the exception comes when the programme hits that line, no matter which value i has.
Tried this too, said that types are incompatible:
float lukui = ((float)luku.get(i)) .floatValue();What am I doing wrong? I couldn't find any good tutorials about using lists, so i'm really lost here.
I'll post the whole code here, if it helps. Sorry about the Finnish variable and method names, but you get the idea :)
package esa;
import java.io.*;
import java.util.*;

As I mentioned, I tried this:
float lukui = ((float)luku.get(i))
.floatValue();And your reply was:
float lukui =
((Float)luku.get(i)).floatValue So the problem really was the spelling, it should
have been Float with a capital F.
From what I understand, Float refers to the Float
class, Correct. And float refers to the float primitive type. Objects and primitives are not interchangeable. You need to take explicit steps to convert between them. Although, in 1.5/5.0, autoboxing/unboxing hide some of this for you.
so why isn't just a regular float datatype
doing the job here, like with the variable lukui?Not entirely sure what you're asking.
Collections take objects, not primitives, and since you put an object in, you get an object out. You then have to take the extra step to get a primitive representation of that object. You can't just cast between objects and primitives.
Again, autoboxing will relieve some of this drudgery. I haven't used it myself yet, so I can't comment on how good or bad it is. -
A lot of problems with Oracle BI SEE 11g
I have a lot of problems with Oracle BI SEE 11g
1. I upgraded my BI SEE 10 repository and can it openning in offline mode.
2. I can't deploy my upgraded repository in EM MW Control 11g - when i try to open Farm_bifoundation_domain->Business Intelligence->coreapplication, i get error "Stream closed
For more information, please see the server's error log for an entry beggining with: Server Exception during PPR, #41".
Opening Logs by EM control doesn't work too.

3. Ok, i taking sample repository and adding a new datasource in it:
Database: Oracle 8i
Connection pool:
Call interface OCI 8i/9i
Data source name:
(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP) (Host = oraapp) (Port = 1521) ) ) (CONNECT_DATA = (SID = MYSID) ) )
This settings are working fine in BI 10.
In BI 11g i get this funny error: "The connection has failed". I lost my time in attempts to connect to Oracle DB 8, but have not results. After that i hacked button "Query DBMS" at "Features" tab, pressed it and when get error "ORA-03134: Connections to this server version are no longer supported.".
Therefore Oracle 8 DB as datasource not supported. Am i right?
4. In sample repository i added oracle DB 10 as datasource, then added two dual tables and their connection to all layers.
Now i open BI Answers, and trying to create report with one dummy column, Now i have this error:
Error

A lot of problems with Lion Server in Mac Mini Server
I have a new Mac Mini Server and I have a lot of problems.
The server application works well for a day, then start to have problem, for example: I can not change the configuration of the share folder, I add a new user but he can not see some folders.
Then if I login the Mac Mini with another user, he can not see the starting folder and if you open a new folder you see a lot of strange documents.
Later, with administrator user, I can not login the server application, I put the user name and password but it refuses it (user name and passowrd are correct)
In the end I also can not login the computer.
I reinstalled the Lion Server 2 times but nothing change, after 2 days it doesn't work like before.
I'm very upset, this is the first time in more then 20 year I have a problem with an Apple computer.
What can I do?

Problem with IN OUT Number, OUT RefCursor for EF Model StoredProcedure call
When I call a stored procedure using the EF Model and implicit binding via App.config which has three parameters i.e. 'IN Number', 'IN OUT Number' and 'OUT sys_refcursor', the 'IN OUT Number' is not set correctly on return from the procedure.
The 'IN OUT Number' is for an error code and is set to 12345 on input and is then set to 54321 by stored proceedure for return.
The correct value is returned when the call is via OracleCommand using implicit binding via App.config but remains unchanged when the call is via EF Model and implicit binding via App.config.
The ODP documentaion says you cannot have two OUT RefCursors when using EF Model but does not say you cannot have OUT RefCursor and other non-RefCursor OUT parameters.
The idea behind this type of procedure is to have multiple input parameters to configure and filter the stored procedure and an output result set that consists of an error code and a collection of result rows in a RefCursor.
I am using 11g R2 database and ODP 11g Release 2 (11.2.0.2.30) and ODAC Entity Framework beta.
The query uses Scott/tiger schema with parameters department code, error code and list of employees for department.
code:
PROCEDURE TEST_PARAMETERS
DEPT IN NUMBER,
ERROR_CODE IN OUT NUMBER,
DEPT_EMPLOYEES OUT sys_refcursor
AS
BEGIN
DBMS_OUTPUT.PUT_LINE('DEPT = [' || DEPT || ']');
DBMS_OUTPUT.PUT_LINE('ERROR_CODE = [' || ERROR_CODE || ']');
OPEN DEPT_EMPLOYEES for SELECT empno, ename from emp where deptno = DEPT;
-- set ERROR_CODE for return
ERROR_CODE := 54321;
END TEST_PARAMETERS;
The App.config for implicit RefCursor binding is as follows ...
<oracle.dataaccess.client>
<settings>
<add name="SCOTT.TEST_PARAMETERS.RefCursor.DEPT_EMPLOYEES"
value="implicitRefCursor bindinfo='mode=Output'" />
<add name="SCOTT.TEST_PARAMETERS.RefCursorMetaData.DEPT_EMPLOYEES.Column.0"
value="implicitRefCursor metadata='ColumnName=EMPNO;
BaseColumnName=EMPNO;BaseSchemaName=SCOTT;BaseTableName=EMP;
NATIVE_DATA_TYPE=number;ProviderType=Int32;
PROVIDER_DB_TYPE=Int32;DataType=System.Int32;
ColumnSize=4;NumericPrecision=10;
NumericScale=3;AllowDBNull=false;IsKey=true'" />
<add name="SCOTT.TEST_PARAMETERS.RefCursorMetaData.DEPT_EMPLOYEES.Column.1"
value="implicitRefCursor metadata='ColumnName=ENAME;
BaseColumnName=ENAME;BaseSchemaName=SCOTT;BaseTableName=EMP;
NATIVE_DATA_TYPE=varchar2;ProviderType=Varchar2;
PROVIDER_DB_TYPE=String;DataType=System.String;
ColumnSize=10;AllowDBNull=true'" />
</settings>
</oracle.dataaccess.client>
When the call is via OracleCommand both outputs are correct i.e. ERROR_CODE gets set to 54321 and the correct emplyees for department 10 are returned
code:
private void TestParametersViaOracleCommand()
try
string constr = "DATA SOURCE=ORCL;PASSWORD=tiger;PERSIST SECURITY INFO=True;USER ID=SCOTT";
OracleConnection con = new OracleConnection(constr);
con.Open();
OracleCommand cmd = con.CreateCommand();
OracleDataAdapter adapter = new OracleDataAdapter(cmd);
DataSet ds = new DataSet();
cmd = con.CreateCommand();
cmd.CommandText = "SCOTT.TEST_PARAMETERS";
cmd.CommandType = CommandType.StoredProcedure;
cmd.BindByName = true;
OracleParameter dept = cmd.Parameters.Add("DEPT",
OracleDbType.Int32,
ParameterDirection.Input);
dept.Value = 10;
OracleParameter errorCode = cmd.Parameters.Add("ERROR_CODE",
OracleDbType.Int32,
ParameterDirection.InputOutput);
errorCode.Value = 12345;
// RefCursor output parameter implicitly bound via App.Config
adapter = new OracleDataAdapter(cmd);
adapter.Fill(ds);
// should be 54321 and is ...
Console.WriteLine("after call errorCode.Value = " + errorCode.Value);
Console.WriteLine("list size = {0}", ds.Tables[0].Rows.Count);
// only one table
DataTable deptEmployeesTable = ds.Tables[0];
for (int ii = 0; ii < deptEmployeesTable.Rows.Count; ++ii)
DataRow row = deptEmployeesTable.Rows[ii];
Console.WriteLine("EMPNO: " + row[0] + "; ENAME: " + row[1]);
catch (Exception ex)
// Output the message
Console.WriteLine(ex.Message);
if (ex.InnerException != null)
// If any details are available regarding
// errors in the app.config, print them out
Console.WriteLine(ex.InnerException.Message);
if (ex.InnerException.InnerException != null)
Console.WriteLine(
ex.InnerException.InnerException.Message);
output:
before call errorCode.Value = 12345
after call errorCode.Value = 54321 (should be 54321!)
list size = 3
EMPNO: 7782; ENAME: CLARK
EMPNO: 7839; ENAME: KING
EMPNO: 7934; ENAME: MILLER
However when call is via EF Model the correct employees are returned but the ERROR_CODE parameter is unchanged on return.
code:
private void TestParametersViaEFModel()
var context = new ScottEntities();
Decimal dept = 10;
ObjectParameter errorCodeParameter = new ObjectParameter("ERROR_CODE", typeof(decimal));
errorCodeParameter.Value = 12345;
Console.WriteLine("before call errorCodeParameter.Value = " + errorCodeParameter.Value);
// RefCursor output parameter implicitly bound via App.Config
var queryResult = context.TestParameters(dept, errorCodeParameter);
// should be 54321 and is ...
Console.WriteLine("after call errorCodeParameter.Value = " + errorCodeParameter.Value + " (should be 54321!)");
List<TestParameters_Result> deptEmployeesList = queryResult.ToList();
Console.WriteLine("list size = {0}", deptEmployeesList.Count);
for (int ii = 0; ii < deptEmployeesList.Count; ++ii)
TestParameters_Result result = deptEmployeesList[ii];
Console.WriteLine("EMPNO: " + result.EMPNO + "; ENAME: " + result.ENAME);
output:
after call errorCodeParameter.Value = 12345 (should be 54321!)
list size = 3
EMPNO: 7782; ENAME: CLARK
EMPNO: 7839; ENAME: KING
EMPNO: 7934; ENAME: MILLER
errorCodeParameter.Value IS NOT CORRECTLY RETURNED!
If there is no RefCursor then both outputs are identical i.e. the parameters are being passed in correctly and the problem is not with the 'IN OUT' parameter. Also same thing is true if ERROR_CODE is made an OUT parameter. Also tried changing the position of the parameter in the list but still get same problem i.e. works when OracleCommand but not when EF Model. Also note that the RefCursor results are correct for both types of call i.e. it is just a problem with the value of the 'IN OUT ERROR_CODE' parameter.
I have also enabled debug stepping from Visual Studio 2010 into Oracle PL/SQL as described in
"http://st-curriculum.oracle.com/obe/db/hol08/dotnet/debugging/debugging_otn.htm"
and have verified by inspection that the correct values are being passed into the stored procedure and that the stored procedure is definitely setting the ERROR_CODE to 54321 prior to return.
Most of our stored procedures have these type of parameters i.e. several IN params to configure the work of the stored procedure, an OUT NUMBER parameter for the Error_Code if any and a RefCursor for the result list.
Is this a bug or a feature? Am I doing something wrong?Just to clarify ....
If the ERROR_CODE parameter is made an 'OUT' parameter instead of an 'IN OUT' parameter the correct return value is given for the OracleCommand invocation but the WRONG value is still returned for the EF Model invocation i.e. just changing the parameter from 'IN OUT' to just 'OUT' does not fix the problem. -
Problem with temporary table refresh
Hi,
I running a process before validation on a page to populate a temporary table when I click a button.
On the following page I've built a shuttle on the temporary table. Not the most elegant solution, but the shuttle LOV box wouldn't process the oracle text commands in the SQL.
I'm not getting any error, but I have an unusual problem
It takes two passes for the data to be replaced. i.e I enter 'ABCD' in the filter and it returns data with 'ABCD'
If I return to the page and change the filter to 'EFGH' I still get 'ABCD'. I return to the page and click the button again and I get 'EFGH' results
I've checked the data in the temporay table and that is updating in line with the problem.
I've looked at the debug and that seems fine (i.e I can see the changed filter value), I've tried moving the truncate to a different process, that didn't help.
I've run it in SQL developer and it seems to work fine.
I've included the code below, but I can't see a problem with it.
Can anybody help?

end;Hi,
Apex does not work well with temporary tables as you cannot guarantee which session from the pool will be used to serve each page.
In your case, it looks like the second page is using temporary data from the wrong session.
Have you considered using Apex Collections instead?
