OVD Database Adapter w/ JDBC Thin Driver to 10G RAC DB Resource

I'm looking for feedback as to whether anyone has successfully consumed a RAC database resource through an OVD database adapter? If so, I am interested in what your host value in the adapter ui looked like.
I am successful with this connection only if I go against one of the RAC nodes directly, thus losing redundancy.
This is OVD 10G 10.1.4.3 on RHEL4
RAC DB 10G
I have tried:
(DESCRIPTION=(ADDRESS_LIST=(LOAD_BALANCE=ON)(ADDRESS=(PROTOCOL=TCP)(HOST=10.26.4.203)(PORT=1540))(ADDRESS=(PROTOCOL=TCP)(HOST=10.26.4.204)(PORT=1540)))
(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = myhost)(PORT = 1540))(ADDRESS = (PROTOCOL = TCP)(HOST = myhost2)(PORT = 1540))(LOAD_BALANCE = yes)(CONNECT_DATA = (SERVICE_NAME = SCHTESTS)(FAILOVER_MODE = (TYPE = SELECT)(METHOD = BASIC)(RETRIES = 200)(DELAY = 5))))
(DESCRIPTION=(LOAD_BALANCE=on)(ADDRESS=(PROTOCOL=TCP)(HOST=myhost)(PORT=1540)) (ADDRESS=(PROTOCOL=TCP)(HOST=myhost2)(PORT=1540))(CONNECT_DATA=(SERVICE_NAME=SCHTESTS)))
OVD Manager seems to anticipate this format because it then rejects inputs on the host and port form fields which I take as a positive indicator.
Otherwise, this feels like taking shots in the dark...
Any assistance or feedback is much appreciated.
Mark

Sorted this out:
Used custom URL and made sure that the OVD Manager IDE was not appending any additional information following the closing bracket of the URL.
The full successful URL was as follows with no values in any of the other fields:
jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=on)(ADDRESS = (PROTOCOL = TCP)(HOST = host1)(PORT = 1540))(ADDRESS = (PROTOCOL = TCP)(HOST = host2)(PORT = 1540))(CONNECT_DATA=(SERVICE_NAME=SNAME)))

Problem in connecting to database using oracle jdbc thin driver

hi
i am trying to connect to a database using oracle thin driver.
i am getting following error:
java.sql.sqlexception:Io exception: the network adapter could not establish the connection
Io exception: the network adapter could not establish the connection
the connection string has the property of using a dedicated server
for this reason i have put USE_DEDICATED_SERVER=ON in sqlnet.ora file...
we did not face this problem while connecting to other databases which do not have the property of dedicated server in their connection string in tnsnames.ora file.
please suggest a solution for this.
thanks and regards,
asif

If you are using the thin driver, sqlnet.ora does not come into play. None of Oracle networking does. That is one of the great things about using the thin driver, no need to have the client installed.
That error is due to incorrect connection info you are supplying or the machine you are connection from can't ping the machine it is trying to connect to.

Connection error to 9i database using JDBC thin driver

When trying to connect to a new 9i database using the JDBC thin driver, I received the following error:

I have no problem with my code connecting to an Oracle 8 database, just 9i.
I'm trying to debug in Visual Cafe (JDK 1.1.7) and have both the classes111.zip and the nls_charset11.zip in my CLASSPATH.
Any suggestions would be appreciated. Thanks

If you're using 8i 8.1.7.1 or 8i 8.1.7.0 thin JDBC drivers on NT, then you can get them to connect to 9i by applying the 8i 8.1.7.1 Patch available at:
http://technet.oracle.com/software/tech/java/sqlj_jdbc/htdocs/solsoft.html
You might have to register/login first.
Basically, it's just a case of replacing a class already in your classes111.zip or classes12.zip with the class in the patch.
Took me a while to find this, but it worked first time after patching. Hope this helps.

JDBC Thin driver doesn't support writing data into remote database via database link

Dear Oracle Guru:
Please confirm: Oracle JDBC thin driver does not support writing data to remote database via database link.
The following errors occur when trying to write data into a remote database via database link through jdbc thin driver:
ORA-03106: fatal two-task communication protocol error
ORA-02063: preceding line from FDBE.PAPDSRAS1
ORA-02063: preceding 2 lines from PA
SQL statement is a prepared statement using a SQL like: insert into mytable@pa (col1,col2) values (?,?).
Thanks.
null

Thanks, Dan.
I still think it is a driver problem, because I can do similar things in a stored procedure or in PL/SQL Developer to copy records from a local database table to a remote database table via database link (insert into mytable@pa select * from mytable). The value for distributed_transactions of our database is 10.

Problems with jdbc thin driver (Euro Symbol)

Hello,
at the moment it is impossible for me to write or read euro characters to a database using a jdbc thin driver.
I am using
ojdbc14.jar (version 10.2.0.3.0) and orai18n.jar (also) together with JDK 1.4.2.
Charset of the database is WE8MSWIN1252. It does not work on ORACLE 9.2.0.1, 9.2.0.6 and 10.2.0.2.0 (others I have not tried). But the problem seams to be in thin client.
Inserting Eurosymbols using a PreparedStatement works quite well. Using a normal Statement does not work.
Also the values getting from a ResultSet are incorrect.
After several test I downloaded a patch 4659157 for ojdbc14.jar and 5470375 for orai18n.jar. After installing the patch the euro characters were returned, but:
In several selects of numeric fields (not all, seams to be random) my resultset returned the Euro character instead of 0 and so on.
Driver for 9.2 works quite well, but does not support 10g Release 2 (and contains also some funny bugs)
Following solutions are not suitable for us:
Changing the character set of the database (come on, this cannot be serious. I cannot change the character set of more than 100 databases)
Using the newest driver (ORACLE 11). We are still using JAVA 1.4.2 and cannot migrate our application at the moment.
Using an oci client. Not possible, no ORACLE client on clients...
Has anyone an idea how to deal with this?
Does anyone know when ORACLE is going to release a new jdbc driver for JAVA 1.4.2 (maybe 10.2.0.4.) ??
Regards,
Christian

Just installed PATCH 4659157 and 5470375 from metalink. The Euro problem seams to be corrected.
BUT:
Another problem occurred. Sometimes numeric values are returned wrong (0 from a numeric field comes as euro, 1 comes as Á (2 and 3 too).
This error seams to be random to me.
Our application is selecting a rowid from a table and after that fills several textfields in a frame by selecting the content in a way like this:
select [column1] from [table] where rowid=[rowid]
select [column2] from [table] where rowid=[rowid]
if I select the numeric column with select nr. 77 I get a wrong value. If I select it at nr. 10 I get the correct value.
The selects are done by a normal Statement object creating a ResultSet. The Value from the ResultSet is fetched by getObject() method.
I also tried to write a test program executing only the selects of the application, but it gives me correct results.
Also when selecting all the fields in one select I get a correct result.
Using a different charset than WE8MSWIN1252 seams to give correct results. Using the OCI driver returns correct results.
Using ojdbc14.jar and orai18n.jar Release 10.2.0.3. unpatched produces the same error (and does not return Euro symbols)
Using ojdbc14.jar and orai18n.jar Release 10.2.0.2. returns correct results (but wrong Euro)
Has anyone had the same problem yet?
Regards,
Christian

Jdbc oracle jdbc-thin driver subname

I am working on Windows 2000 environment, using oracle8i 8.1.7 JDBC-Thin driver for use with JDK 1.2.x. The oralce8i 8.1.7 database is on another linux box. I can access the linux box through its ip address, but not by its hostname since it's not accessiable by the dns server. In my code, in the JDBCUrl, I used ip address instead of the hostname, e.g. "jdbc:oracle:thin:@10.0.113.108:1521:ora1". But I got the error like: "java.sql.SQLException: Io exception: The Network Adapter could not establish the connection". If I add a entry in my working machine's hosts file to map the hostname, I can fix the problem. But I don't know if this is the solution, or there is other better solutions.
Thanks
null

Using a hosts file entry is a common solution for problem where the dns lookup does not contain an entry for a RDBMS server platform.
The real solution is to resolve this issue :
"where the dns lookup does not contain an entry for a RDBMS server platform."

How does Oracle JDBC thin driver handle numbers via getString?

Hi,
I have a query regarding how numbers are handled by the oracle jdbc thin driver. The issue I am facing is with regards to the decimal separator (. is en_US and , in pt_BR)
e.g. Consider the below code,
Connection conn = DriverManager.getConnection(...);
Statement stmt = conn.createStatement();
ResultSet rset = stmt.executeQuery("select value from test_table1");
while (rset.next())
System.out.println (rset.getString(1));
test_table1 has a single column of sql type 'number' with a single row having value "123.45"
NLS_NUMERIC_CHARACTERS = ".,"
Database version = 10.2.0.2.0
There is a (generic) method to which a ResultSet is passed and it returns a dictionary of key value pairs. All column values from the ResultSet are retrieved using getString method of ResultSet.
My question is whether the jdbc driver formats numbers (based on the locale) before returning it as a string as part of the getString method?
e.g.
java -Duser.language=pt -Duser.region=BR TestJDBC
prints "123.45" and not "124,45"
Is there a reason why getString always retrieves a number column value with '.' as the decimal separator?
To help make things a bit more clear, all the column values retrieved are then converted into an XML (and hence the conversion to string)
At present, the only way I see out of this is to handle numbers differently.
i.e. something similar to,
if (resultsetmetadata.getcolumntype .. = double OR float OR int OR long.. )
NumberFormat.getInstance().format(rset.getDouble(1));
Is there a better way to resolve this issue?
Thanks,
Binoy

user565580,
As has been already stated, Oracle does not have data-types INTEGER or SMALLINT, only NUMBER.
So even though Oracle lets you write INTEGER, it really creates a NUMBER.
(As Joe mentioned.)
Other databases don't have a NUMBER data-type, they have INTEGER, SMALLINT, etc.
Originally, Oracle database only had three data-types:
CHAR
DATE
NUMBER
If you're going to be working with Oracle database, then you need to adapt yourself to its limitations.
So you'll probably need to define NUMBER data-types using scale and precision.
(As Kuassi mentioned.)
Good Luck,
Avi.

Error Code Definition for JDBC Thin driver

Would like to know where I can find the definition of error codes
for JDBC thin driver to Oracle 7 database. Right now, when I have
database errors, I get SQL execption with CODE=XXXXXX. Need to
know the definition of the error codes in order to decide whether
the application shall retry or quit or do something else. Thank
you in advance.

Hi,
thin client session Language is controlled by java Locale.
Based on testing code, ORA- messages are localized after the connection is successfully established. ORA- messages returned in the middle of connecting are in instance language.
So, as far as I can say, you need to catch exceptions from DriverManager.getConnection(url, info); and translate them on your own.
Once the connection is successfully returned, ORA- message language is defined by java Locale.
Tests were performed on Oracle 10gR2 (both thin driver and DB).

Oracle JDBC Thin Driver

I am using CLOBS with the Oracle thin driver and am experiencing horrible performance. We need datavalues more than a VARCHAR2 and have used CLOB but the method Oracle uses to get the data in and out is super slow.
MS SQL Server JDBC with text is awesome and fast. But Oracle is slow and very cumbersome.
Help

We are using 9.0.2.
So what you are saying is although the column is CLOB
in Oracle 10 g we can use a normal result set
rset.getString( 1 ) no special oracle stuff just the
e Oracle thin driver for 10g?
Also this will retrieve a String greater than 4000
bytes?Exactly. Not only you can retieve a clob as string, you can also insert clob
as a string too. Here is the code I referred in last post in case you do not

Using Oracle JDBC Thin Driver

We are trying to use the Oracle supplied JDBC thin driver directly from within a jar file we add for our application.
The classes in the jar file directly connect to an oracle database via the thin driver.
The problem we've encountered is that if the JDBC Connection object is held in memory, after some time, the connection times out for no reason.
Is there some restriction with weblogic in connecting directly to database from a class file and then caching the connection reference? It almost seems as if weblogic is severing the connections.
thank you,
BJ

Stefan,
You are right, although I would recommend just having the
TestConnectionOnReserve= true and the testTableName set. Refresh Minutes
becomes kind of redundent when you set these values.
TestConnsOnReserve allows the server to verify if a connection that the
client/application has requested is good , otherwise it recreates this
connection and gives it to the client/application.

Hi Sree,
If instead a WL connection pool would be used this issue could be solved
using
"Refresh Period" and TestTableName right? In this case the connection would
be
alive as long as WL server is up. As a bonus we would have an automatic
reconnection
after an Oracle server reboot?
thanks, stefan

Hi BJ,
When you get connection directly using the Oracle thin driver, this is
for
sure your database timing out the connection when no activity is detected
for sometime. You should consult with your DBA to ensure this timeout
is set
to a higher value at the server or ensure you dont hold on to theconnection
for long durations or ensure you handle this situation by triggering
a
generic oracle process so that you periodically keep the connection busy
to
ensure that the database does not close it.
This shouldnt be anything to do with WebLogic as you dont seem to be
using
WebLogic connection pool.

JDBC thin driver pads CHAR col to byte size when NLS_LENGTH_SEMANTICS=CHAR

We're using an Oracle 9.2 database with the database character set specified as AL32UTF8 with NLS_LENGTH_SEMANTICS set to CHAR. I've reproduced this problem with both the "classes12.zip" and "ojdbc14.jar" available with the Oracle 9.2 client installation.
The problem occurs with the JDBC thin driver. The problem does not occur with the JDBC OCI driver (nor SQL*Plus 9.2).
There are 2 relatively simply workarounds: use the OCI driver or convert CHAR columns to VARCHAR2 columns. I'm mostly curious as to whether there is some kind of setting for the thin driver to circumvent this problem, or if this is actually expected behavior. We're not that familiar with the NLS_LENGTH_SEMANTICS setting.
Consider a table as follows:
create table my_table (status CHAR(1));
If I describe the table it correctly shows the column using CHAR semantics.
STATUS CHAR(1 CHAR)
Given the AL32UTF8, this means that 4 bytes of storage are reserved for this column.
If I insert a single ASCII character in this table (for example "A") then read it back using the JDBC thin driver, I get the string "A " - the letter A followed by 3 spaces. In other words, the thin driver appears to have padded the value to its BYTE length. The OCI driver and SQL*Plus do not pad the value.
I understand that CHAR columns are normally blank padded when the data size is shorter than the defined column length, but I think that with NLS_LENGTH_SEMANTICS=CHAR, the padding should be based on the length of the column in chars, not in bytes.
Can anyone shed some light on this issue?
Thanks in advance,
Tim

Update:
I guess I should mention we're using Java 2 SDK 1.4.1_01 on Windows XP with an Oracle 9.2 database on Windows 2000.

Change expired password using oracle jdbc thin driver

Hello,
I have a java program that uses the oracle jdbc thin driver (ojdbc6 - version 11.2.0.3) for database connection. My question is if I have any possibility to change an expired password (java.sql.SQLException: ORA-28001: the password has expired) using the thin driver - NOT OCI?

No - the thin driver doesn't have any password management features.
