Reporting bugs in oracle products

Is there a webpage whre I can report bugs in oracle
products.
Thanks,
Artur...

The only place I'm aware of short of calling Oracle is metalink.oracle.com but you have to have paid for Oracle support to access
the web site. From there you can file a TAR(Technical Assistance Request) and a support person will research your problem and
either find an existing fix or classify it as a new bug.

My thread is gone! Is it undesired to post bugs about Oracle Products here?

A few days ago i posted a thread here about a bog in ODP.NET Driver 10.2.0.2.10 Beta
Now this thread seems deleted.
Is it undesired to post bugs about Oracle Products here?

Thank you Mark for the info.
The practise to delete posts without any comments casts a damning light on Oracle and can gives the impression that oracle the way of repairing bus is to hide them.
For a cutomers like me that invets time to analyze issues in oracle software and invets time again to post them here to help Oracle it is very disappointing to see that my posts are delete without comments.
Oracle should think about that mistreating their customers is not a fine way. This is unsuitable for giving custumers the feeling that Oracle is intrested in their problems.
The right way would be to delete the content of a post intead of the complete thread and give a small comment why it has ben removed.
Sorry for this harsh post, but in the last monts i am more and more disappointed about the faultiness of Oracle products, the slowness of Oracle Support and the false promises regarding to meeting deatlines.
I have the feeling to be on a sinking ship with Oracle.
This Forum here is sometime a ray of hope but the rest of Oracle...

Is this Oracle Reports bug – "break order property" in "group above" report

Is this Oracle Reports bug – “break order property” in "group above" report
Could anybody confirm that in "group above" report, we could only order the brake column's values with ""none" or "ascending" or "descending" provided by "break order property"?
In the following example, “Dept” is brake column. Oracle Reports allows us to order values in “Dept” with “descending” provided by “break order property”:
Dept 30
job ename salary
xxx xxx xxx
xxx xxx xxx
Dept 20
job ename salary
xxx xxx xxx
xxx xxx xxx
Dept 10
job ename salary
xxx xxx xxx
xxx xxx xxx
or “ascending” provided by “break order property”:
Dept 10
job ename salary
xxx xxx xxx
xxx xxx xxx
Dept 20
job ename salary
xxx xxx xxx
xxx xxx xxx
Dept 30
job ename salary
xxx xxx xxx
xxx xxx xxx
I need to do:
Dept 20
job ename salary
xxx xxx xxx
xxx xxx xxx
Dept 10
job ename salary
xxx xxx xxx
xxx xxx xxx
Dept 30
job ename salary
xxx xxx xxx
xxx xxx xxx
Could I do this? Could anybody confirm that we could never ever do this, or If yes, how?
Millions of thanks for advice.
M.Z.

Why should that be a bug? You have a custom requirement and have to find a way to fulfill it. But, what is your actual sorting order? Do you have only this three departments? If so, you could add an addtional column in your query like
DECODE(DEPT, 20, 1, 10, 2, 30, 3, 4) SORTINGput that column in the same group as dept and sort after that new column.

Column Privilege Security Bug in Oracle 9i

There seems to be a bug in matching column privileges between VIEW and TABLE objects. In the SQL script below, this bug lets users INSERT values into columns that they do not have INSERT privileges on. (I guess that the bug would also let people UPDATE columns they do not own).
This is the first time I've come into this forum, so please accept my appologies if this is the wrong place to report bugs, or this bug is already widely known.
Adam
In the following scripts, SYSTEM grants INSERT on column A, but column B gets inserted.
SQL> connect system/manager @DB2
SQL> create table t1(a int,b int,c int);
SQL> create user adam identified by adam;
SQL> grant create view to adam;
SQL> grant select on t1 to adam;
SQL> grant insert(a) on t1 to adam;
SQL> connect adam/adam @DB2
SQL> create view v1 as select b y,c z,a x from system.t1;
SQL> insert into v1(y) values(1);
SQL> commit;
SQL> connect system/manager @DB2
SQL> select * from t1;
A B C
1

I've given here the required details:

Though the two sql statements should give the same result, it is not so.

Oracle Reports 6i with Oracle 8.1.7?

Solaris 7 (sparc)
Oracle RDBMS 8.1.7
Reports 6i (release 2)
I am trying to install Reports 6i on a machine that has Oracle RDBMS 8.1.7 installed already. The last time I tried installing to the same ORACLE_HOME it corrupted all my executables. After reading the docs again, I noticed the Reports docs say Reports requires Orcle 8.0.6. I thought it might be better to install to a new ORACLE_HOME (/u01/app/oracle/product/8.0.6), however, there is no RDBMS installed there and the installer complains.
Could someone offer some suggestions on how it should be installed in this type of environment. What steps should be followed to allow Oracle Reports 6i to co-exist peacefully on the same machine/ORACLE_HOME as the Oracle 8.1.7 instance.
Thanks

I found the answer myself in an earlier post.

How to add a new font into Report Builder and Oracle Forms/Reports Server?

Hi,
I've searched the forum and can't find this being discussed.
My developers run Report Builder 10.1.2.0.2 on their XP laptops.
Their reports run (in production) on Oracle Forms/Reports Server 10.1.2.0.2.
This server runs on MS Windows 2003, SP2.
They've got a client who wants reports using the "Garamond Western" font.
So....how do I get this font onto the developer's Report Builder laptops, and onto the Oracle Forms/Reports Server?
I've moved various 'Garamond' fonts into C:\WINDOWS\FONTS on both the laptops and the server, but neither seem to recognize it.
Thanks for your help.

Thanks.
This answers 1/2 of my question.
The developer can now use Report Builder on his laptop, with the new fonts.
But when he moves this new Report to the Oracle Application Server/Forms-Reports Server, it fails to use the new fonts.
The Oracle App Server/Forms-Report Server is Version 10.1.2.0.2. It runs on MS Windows 2003, SP2.
I have installed the exact same fonts on this server, into C:\WINDOWS\Fonts.
I have used REGEDIT to change REPORTS_PATH....and placed C:\WINDOWS\Fonts; as the first value in this field.
I have then stopped and restarted the Forms-Reports Server.

Install and configure report service on Oracle Application Server 10g

i want to know how to install and configure report service on Oracle Application Server 10g Release 3 (10.1.3.1.0)
Thanks

the case is that we developed an ADF Application, so we want to deploy it on the latest version of Oracle Application server.
our application communicate with Oracle reports (run oracle reports from our Application) as there are no Oracle report products for JEE Application.
so if there are not report service that can run on Oracle Application Server 10g Release 3 (10.1.3.1.0),
what is the other choices that oracle supports that can help us in this case ???

Multiple Oracle Products on Single Server

Can we install Multiple Oracle Products for Development and Testing on a Single Server?
Oracle Database 9i Enterprise Edition.
Oracle 9i Application Server
Oracle Applications 11i (Financials GL,HRMS PAYROLL)
Oracle Discoverer 4.x
Oracle Internet Developer Suite (Forms Server, Reports Server,
If yes,
Do they need to be in separate ORACLE_HOME or same ?
Also what should be the sequence of Install, i.e. what should be installed first?

The following products needs to be in their own Oracle Home:
Oracle Database 9i Enterprise Edition. --> in its own O_H
Oracle 9i Application Server --> in its own O_H (assuming this is 1.0.2.2 or 9.0.2)
Oracle Applications 11i (Financials GL,HRMS PAYROLL) --> in its own O_H
Oracle Discoverer 4.x --> in its own O_H (this is a 806 based product btw)
Oracle Internet Developer Suite (Forms Server, Reports Server) --> This can either be in its own O_H or in the O_H which has 1.0.2.2 Oracle9i Application Server.

Bug in Oracle JDBC Pooling Classes - Deadlock

We are utilizing Oracle's connection caching (drivers 10.2.0.1) and have found a deadlock situation. I reviewed the code for the (drivers 10.2.0.3) and I see the same problem could happen.
I searched and have not found this problem identified anywhere. Is this something I should post to Oracle in some way (i.e. Metalink?) or is there a better forum to get this resolved?
We are utilizing an OCI driver with the following setup in the server.xml
<ResourceParams name="cmf_toolbox">
<parameter>
<name>factory</name>
<value>oracle.jdbc.pool.OracleDataSourceFactory</value>
</parameter>
<parameter>
<name>driverClassName</name>
<value>oracle.jdbc.driver.OracleDriver</value>

<value>(InitialLimit=5,MinLimit=15,MaxLimit=75,ConnectionWaitTimeout=30,InactivityTimeout=300,AbandonedConnectionTimeout=300,ValidateConnection=false)</value>
</parameter>
</ResourceParams>
We get a deadlock situation between two threads and the exact steps are this:
1) thread1 - The OracleImplicitConnectionClassThread class is executing the runAbandonedTimeout method which will lock the OracleImplicitConnectionCache class with a synchronized block. It will then go thru additional steps and finally try to call the LogicalConnection.close method which is already locked by thread2
2) thread2 - This thread is doing a standard .close() on the Logical Connection and when it does this it obtains a lock on the LogicalConnection class. This thread then goes through additional steps till it gets to a point in the OracleImplicitConnectionCache class where it executes the reusePooledConnection method. This method is synchronized.
Actual steps that cause deadlock:
1) thread1 locks OracleImplicitConnectionClass in runAbandonedTimeout method
2) thread2 locks LogicalConnection class in close function.
3) thread1 tries to lock the LogicalConnection and is unable to do this, waits for lock
4) thread2 tries to lock the OracleImplicitConnectionClass and waits for lock.

We used a documented option to abandon connects in the case of an unforeseen error. The consequence of using this option was not a graceful degradation in performance but a complete lockup of the application. The scenario in which we created a moderate number of abandoned connections was a rare error scenario but a valid test.
How could this not be a bug in the Oracle driver? Is dead-lock a desireable outcome of using an option? Is dead-lock ever an acceptable consequence of using a feature as documented?
Turns out other Oracle options to recover from an unexpected error also incur a similar deadlock (TimeToLiveTimeout).
I did a code review of the decompiled drivers and it clearly shows the issue, confirming the original report of this issue. Perhaps you have evidence to the contrary or better evidence to support your statement "not a bug in Oracle"?
Perhaps you are one of the very few people who have not experience problems with Oracle drivers? I've been using Oracle since 7.3.4 and it seems that I have always been working around Oracle JDBC driver problems.
We are using Tomcat with the OracleDataSourceFactory.

Bug in Oracle JDBC thin driver (parameter order)

[ I'd preferably send this to some Oracle support email but I
can't find any on both www.oracle.com and www.technet.com. ]
The following program illustrates bug I found in JDBC Oracle thin
driver.
* Synopsis:
The parameters of prepared statement (I tested SELECT's and
UPDATE's) are bound in the reverse order.
If one do:
PreparedStatement p = connection.prepareStatement(
"SELECT field FROM table WHERE first = ? and second = ?");
and then bind parameter 1 to "a" and parameter to "b":
p.setString(1, "a");
p.setString(2, "b");
then executing p yields the same results as executing
SELECT field FROM table WHERE first = "b" and second = "a"
although it should be equivalent to
SELECT field FROM table WHERE first = "a" and second = "b"
The bug is present only in "thin" Oracle JDBC driver. Changing
driver to "oci8" solves the problem.
* Version and platform info:
I detected the bug using Oracle 8.0.5 server for Linux.
According to $ORACLE_HOME/jdbc/README.doc that is
Oracle JDBC Drivers release 8.0.5.0.0 (Production Release)
* The program below:
The program below illustrates the bug by creating dummy two
column table, inserting the row into it and then selecting
the contents using prepared statement. Those operations
are performed on both good (oci8) and bad (thin) connections,
the results can be compared.
You may need to change SID, listener port and account data
in getConnecton calls.
Sample program output:
$ javac ShowBug.java; java ShowBug
Output for both connections should be the same
--------------- thin Driver ---------------
[ Non parametrized query: ]
aaa
[ The same - parametrized (should give one row): ]
[ The same - with buggy reversed order (should give no answers):

Bug in oracle embedded http listener

Hi there,
I've discovered a bug in the Oracle embedded http listener for our Oracle on RHEL database version 11.1.0.6 where it will return HTTP-400 bad request errors if a cookie is created with a bare comma in the cookie value. To see for yourself, simply create an apex application with an open door authentication and enter a username with a comma in it - page 101 writes the username to a cookie, and then you get HTTP-400 errors.
I'll raise this as a bug at Oracle, but in the meantime I'm frantically trying to figure out a workaround. We have a production site using a standard Apache frontend that we link to Apex applications using mod_rewrite. There are other applications on the site (invision powerboard) which create cookies with bare commas, so we have no control over the creation of these maligned cookies. My thinking is that we might be able to use mod_rewrite rules to weed out the offending cookies and encode the commas so that things continue to work.
Can anyone assist with a workaround?
Many thanks,
Mike

Hi Mike,
perhaps you can try to modify the cookies on the client?
http://scripts.franciscocharrua.com/javascript-cookies.php
Or is it already too late so that you cannot even run the first procedure to inject the javascript code into the first page?
Or, you could configure the DAD to run a stored procedure before anything else:
PlsqlBeforeProcedure
http://download-uk.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_epg.htm
If this is already too late, your only option seems to be to use an Apache as a proxy and modify the cookie value there.

~Dietmar.

BUG in Oracle SQL Developer 3.0.04 on the "generating DLL" with comments?

I'm newbie on oracle, but I think that I found out a bug in Oracle SQL Developer version 3.0.04 on the "generating DLL" tool using "comments".
I will describe the steps that I gave:
I created a view, but after I test it I had to change my “where” condition, so I comment the old code and then I wrote the new “where” condition below. After I done that I tried to look at the sql code of my view using “generating DLL” tool, but oracle sql developer only shown me half of the code, a lot of code were missing. Then I began with some test trying to understand what happen and I notice that if I put an invalid sql code in my comment the generating DLL start working with no problems, for example(pseudo-code):
(COMMENT WITH VALID SQL CODE the "Generating SQL" don't work:)
CREATE OR REPLACE VIEW <user>.<view_name> ( <column1>,<column2> )
AS
SELECT column1, column2
FROM table1
INNER JOIN
(SELECT
FROM table2
INNER JOIN .....
INNER JOIN ....
--where time_stamp = (select max(time_stamp) from .....)
WHERE time_stamp >= TRUNC(sysdate)
) t1 ON t1.ID = ....
AND ..... >= TRUNC(sysdate)
ORDER BY ....
Generating DLL returns this(when the error occurs):
CREATE OR REPLACE VIEW <user>.<view_name> ( <column1>,<column2> )
AS
(COMMENT WITH VALID SQL CODE the "Generating SQL" work with no problems:)
CREATE OR REPLACE VIEW <user>.<view_name> ( <column1>,<column2> )
AS
SELECT column1, column2
FROM table1
INNER JOIN
(SELECT
FROM table2
INNER JOIN .....
INNER JOIN ....
--where
WHERE time_stamp >= TRUNC(sysdate)
) t1 ON t1.ID = ....
AND ..... >= TRUNC(sysdate)
ORDER BY ....
I believe that "Generating DLL" tool have some problem with the comments, I also used /*...*/ to comment but the problem is still active.
I notice as well that if I started to add some more comments along the code, the conditions migth change, so I think the problem is related with "comments" code.
Would you mind telling me if this is a real bug or if I'm doing anything wrong.
Thank you in advance,
Rodrigo Campos
Edited by: 894886 on 3/Nov/2011 5:29

Hi Rodrigo,
Thank you for reporting this. The only bug I see currently logged on a comment affecting the generated View DDL involves ending the last line of the definition with a comment, which treats the ending semi-colon (even if on a different line) as part of the comment. That is actually related to a low-priority bug against an Oracle database API.
Unfortunately, your pseudo-code is a bit complex. Trying a few quick, simpler tests against the standard HR schema did not reproduce the issue. I tried INNER JOIN, and nested SELECTs. It would help greatly if you could provide a test case compilable against one of the standard schema, like HR or SCOTT.

Bug in Oracle's handling of transaction isolation levels?

Hello,
I think there is a bug in Oracle 9i database related to serializable transaction isolation level.
Here is the information about the server:
Operating System:     Microsoft Windows 2000 Server Version 5.0.2195 Service Pack 2 Build 2195
System type:          Single CPU x86 Family 6 Model 8 Stepping 10 GenuineIntel ~866 MHz
BIOS-Version:          Award Medallion BIOS v6.0
Locale:               German
Here is my information about the client computer:
Operaing system:     Microsoft Windows XP
System type:          IBM ThinkPad
Language for DB access: Java
Database information:
Oracle9i Enterprise Edition Release 9.2.0.1.0 - Production
With the Partitioning, OLAP and Oracle Data Mining options
JServer Release 9.2.0.1.0 - Production
The database has been set up using the default settings and nothing has been changed.
To reproduce the bug, follow these steps:
1. Create a user in 9i database called 'kaon' with password 'kaon'
2. Using SQL Worksheet create the following table:
CREATE TABLE OIModel (
modelID int NOT NULL,
logicalURI varchar (255) NOT NULL,
CONSTRAINT pk_OIModel PRIMARY KEY (modelID),
CONSTRAINT logicalURI_OIModel UNIQUE (logicalURI)
3. Run the following program:
package test;
import java.sql.*;
public class Test {
public static void main(String[] args) throws Exception {
java.util.Locale.setDefault(java.util.Locale.US);
Class.forName("oracle.jdbc.OracleDriver");
Connection connection=DriverManager.getConnection("jdbc:oracle:thin:@schlange:1521:ORCL","kaon","kaon");
DatabaseMetaData dmd=connection.getMetaData();
System.out.println("Product version:");
System.out.println(dmd.getDatabaseProductVersion());
System.out.println();
connection.setAutoCommit(false);
connection.setTransactionIsolation(Connection.TRANSACTION_SERIALIZABLE);
int batches=0;
int counter=2000;
for (int outer=0;outer<50;outer++) {
for (int i=0;i<200;i++) {
executeUpdate(connection,"INSERT INTO OIModel (modelID,logicalURI) VALUES ("+counter+",'start"+counter+"')");
executeUpdate(connection,"UPDATE OIModel SET logicalURI='next"+counter+"' WHERE modelID="+counter);
counter++;
connection.commit();
System.out.println("Batch "+batches+" done");
batches++;
protected static void executeUpdate(Connection conn,String sql) throws Exception {
Statement s=conn.createStatement();
try {
int result=s.executeUpdate(sql);
if (result!=1)
throw new Exception("Should update one row, but updated "+result+" rows, query is "+sql);
finally {
s.close();
The program prints the following output:
Product version:
Oracle9i Enterprise Edition Release 9.2.0.1.0 - Production
With the Partitioning, OLAP and Oracle Data Mining options
JServer Release 9.2.0.1.0 - Production
Batch 0 done
Batch 1 done
java.lang.Exception: Should update one row, but updated 0 rows, query is UPDATE OIModel SET logicalURI='next2571' WHERE modelID=2571
     at test.Test.executeUpdate(Test.java:35)
     at test.Test.main(Test.java:22)
That is, after several iterations, the executeUpdate() method returns 0, rather than 1. This is clearly an error.
4. Leave the database as is. Replace the line
int counter=2000;
with line
int counter=4000;
and restart the program. The following output is generated:
Product version:
Oracle9i Enterprise Edition Release 9.2.0.1.0 - Production
With the Partitioning, OLAP and Oracle Data Mining options
JServer Release 9.2.0.1.0 - Production
Batch 0 done
Batch 1 done

     at test.Test.main(Test.java:22)
This is clearly an error - only one transaction is being active at the time, so there is no need for serialization of transactions.
5. You can restart the program as many times you wish (by chaging the initial counter value first). The same error (can't serialize access for this transaction) will be generated.
6. The error doesn't occur if the transaction isolation level isn't changed.
7. The error doesn't occur if the UPDATE statement is commented out.

I have a similar problem
I'm using Oracle and serializable isolation level.
Transaction inserts 4000 objects and then updates about 1000 of these objects.
Transactions sees inserted objects but cant update them (row not found or can't serialize access for this transaction are thrown).
On 3 tries for this transaction 1 succeds and 2 fails with one of above errors.
No other transactions run concurently.
In read commited isolation error doesn't arise.
I'm using plain JDBC.
Similar or even much bigger serializable transaction works perfectly on the same database as plsql procedure.
I've tried oci and thin (Oracle) drivers and oranxo demo (i-net) driver.
And this problems arises on all of this drivers.
This problem confused me so much :(.
Maby one of Oracle users, developers nows cause of this strange behaviour.
Thanx for all answers.

Bug in Oracle 9.2.0.1.0.

I have found a bug in Oracle 9.2.0.1.0.
Here is the bug analysis.
Step 1:
CREATE TABLE T1 ( ENO NUMBER, ENAME VARCHAR2(100));
Step 2:
CREATE TABLE T2 (DNAME VARCHAR2(1000));
Step 3:
INSERT INTO T1 VALUES (1,’KARTHIK’);
Step 4:
INSERINTO T2 VALUES ('VENKATRAMAN');
Commit;
Now try executing this command,
Command:
SELECT * FROM T1 WHERE ENO IN (SELECT ENO FROM T2);
Here table T2 does not contain “ENO”.
But the query returns,
Output:
=====
ENAME
DNAME
1
KARTHIK
VENKATRAMAN
“ENO” column is being fetched from the main query with table T1 and not from the sub query with table T1.
Please verify this bug and kindly provide a response.
Regards,
Karthik

Well, heres my test (10g, for I dont have a 9.2.0.1.0, but I think it´d show the same result):
Connected to:
Oracle Database 10g Enterprise Edition Release 10.1.0.4.0 - 64bit Production
With the Partitioning, OLAP and Data Mining options
SQL> select *
2 from t1;
ENO ENAME
1 KARTHIK
SQL> select *
2 from t2;
DNAME
VENKATRAMAN
SQL> select *
2 from t1
3 where eno in (select eno from t2);
ENO ENAME
1 KARTHIK
SQL> alter table t2 add (eno number);
Table altered.
SQL> select *
2 from t1
3 where eno in (select eno from t2);
no rows selected
SQL> alter table t2 drop (eno);
Table altered.
SQL> select *
2 from t1
3 where eno in (select t2. eno from t2);
where eno in (select t2. eno from t2)
ERROR at line 3:
ORA-00904: "T2"."ENO": invalid identifier
SQL>
But he is getting output of table T2 too se his last postI don´t think so, because he didn´t SELECT it. Would be nice to just copy & paste the output...

Gerd
