Thanks in advance !

Two thoughts.
The first is that 10.2.0.1 is unpatched. Why? It has been two years since its release and no one has applied 10.2.0.2, 10.2.0.3 or 10.2.0.4.
The second is that your question is not a database question but a Java question is you are more likely to get an answer that will help you if you post in a group where it is on-topic.

How can i import procedure with %ROWTYPE in Oracle 10.2 (paris) warehouse b

Hello.
How can i import procedure with %ROWTYPE in Oracle 10.2 (paris) warehouse builder?Everytime i try to do it i get an error message:
API0411: Name should be an empty string.
If i comment out %rowtype i can import it without problems.
I have tried re-creating the procedure in OWB but once again i cannot find the %rowtype anywhere. the %type is there etc. I have tried to use Publish transformation / custom and cannot find %rowtypa there either.
Thank you very much for your help

Just in case you are having the same problem and cannot find any help anywhere - it is a bug in OWB.
I got in touch with Oracle Support and it appears that it is possible to import procedure/package with %ROWTYPE inside it, but it is not possible if the %ROWTYPE is in the arguments.
Just waiting for them to provide me with the bug ID.

How to import oracle.jdbc.OracleConnection

I'm sure this is something I'm supposed to know but it has been about a year since I have worked with JDeveloper and I have forgotten a few things.
I am looking at some code that includes import oracle.jdbc.OracleConnection with a wavy red line that gives the message "import oracle.jdbc.OracleConnection not found."
Where should I start to look for how to repair this?
Thanks,
Gregory

In your project properties, in the libraries and classpath section, add the library "Oracle JDBC".

How can I import data from a csv file into databse using utl_file?

Hi,
I have two machines (os is windows and database is oracle 10g) that are not connected to each other and both are having the same database schema but data is all different.
Now on one machine, I want to take dump of all the tables into csv files. e.g. if my table name is test then the exported file is test.csv and if the table name is sample then csv file name is sample.csv and so on.
Now I want to import the data from these csv files into the tables on second machine. if I've 50 such csv files, then data should be written to 50 tables.
I am new to this. Could anyone please let me know how can I import data back into tables. i can't use sqlloader as I've to satisfy a few conditions while loading the data into tables. I am stuck and not able to proceed.
Please let me know how can I do this.
Thanks,
Shilpi

Why you want to export into .csv file.Why not export/import? What is your oracle version?

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>
</parameter>
<parameter>
<name>user</name>
<value>hidden</value>
</parameter>
<parameter>
<name>password</name>
<value>hidden</value>
</parameter>
<parameter>
<name>url</name>
<value>jdbc:oracle:oci:@PTB2</value>
</parameter>
<parameter>
<name>connectionCachingEnabled</name>
<value>true</value>
</parameter>
<parameter>
<name>connectionCacheProperties</name>
<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.

How can I find the JDBC Driver version

Hi,
How can I find the JDBC Driver version installed on my Sun Solaris machine which
has Weblogic Server 7.0 installed on it. Is there some kind of tool/command to
do so or does Weblogic console say something about it
Thanks

Parikshit KhannaThere is a jdbc DatabaseMetaData call getDriverVersion().
The best thing to do is to download Oracle's latest appropriate
driver from their site, and edit the start-weblogic script to
make sure the downloaded driver is ahead of any weblogic stuff in
the server's classpath. We do ship a driver, but Oracle usually
has a newer better one very soon after that...

How can I import data using .dmp into the table which has more columns then in import

I am building the history for warehouse purpose on Oracle 8i database and want to use the old import (.dmp) files (from oracle 7.3.4) to import data but the underlying table is having few more columns which are not in my old DMP file .. how can I import the data into these altered tables while using the same *.imp files .
Any solutions ?

That is the most obvious solution .. but think of the case when my operational database which is the source of my data is undergoing changes every quarter i.e after every 3 months there are some changes on underlying table structures which means structures of my import files will always be different after evry quarter .. you can imagine the number of temporary import structures I need to create .. can't there be a solution wherein I can write an SQL over the import file to read the data in required format ..

You didn't post the part of the stacktrace that shows the line number that the problem occured on. (Truncated. see log file for complete stacktrace)
Are you sure the problem occured in the code you posted? If so did this line execute and print on the console?
System.out.println("see?");That error can occur when the code used to deserialize an object uses a different version of the class than the version it was serialized with. The code you posted doesn't shown anything that appears to do any deserialization.
Have their been any changes to the environment lately? Upgrades to Java version, WebLogic or the JDBC driver?
