Trying to use OCI Jdbc driver

I'm using OC4J v2, with JDK1.3.1 under Linux
what libs / configs are required to use OCI Jdbc Drivers ?
thanks

Debu, I spent much time searching this forum for answers to the ocijdbcX.dll problems in OC4J. I finally found my answer on Metalink. Apparently this is Bug# 1918517. The recommended fix on metalink for this bug solved my problem and is probably the problem that everyone else is experiencing. Setting LD_LIBRARY_PATH and ORACLE_HOME had no affect on OC4J.

Can't connect using OCI JDBC driver in OC4J 10.1.3.3 standalone

Hi all,
I've recently upgraded my JDev from 10.1.3.2 to 10.1.3.3 and now I'm unable to establish any OCI connections with my local Oracle 10.1.0.4 database. Not even through a connection pool. The strangest thing is that when I test an OCI connection running from JDeveloper it works fine and the JDBC jars and the oci client are exactly the same.
The error is always the same when I execute a test on a connection pool using the OCI driver:
WARNING J2EE DS-00001 Exception occurred testing connection. Exception: java.sql.SQLException: Closed Connection.
If I just change the driver to the THIN one, the same test works. If I take the same URL from the OCI test and use it in a test class and run it inside JDeveloper, it works also.
I've even downloaded the instant client 10.1.0.5 (which happens to be exactly the same version of the JDBC driver that comes with JDev 10.1.3.3) and tried to use it with no success.
THIN connections are working just fine. The problem happens only when I try to connect via OCI and this problem was not happening in version 10.1.3.2.
Any help?

I found the cause of this problem. It turns out that you must be very careful with the environment variable ORACLE_HOME. On Windows, normally, we don't even set this variable because most applications are able to get it from the system's registry.
Well, it happened that I've edited the script start_oc4j.bat and, for organization reasons, I set the ORACLE_HOME variable with my JDeveloper's home directory (which is the same as my OC4J standalone's). By doing that, I kind of confused the OCI client. Once I removed the "set ORACLE_HOME=C:\JDev" line from the script, everything worked just fine again.
So, always remember: avoid setting environment variable ORACLE_HOME when using Windows and, if you must set it, be sure to do it right.

How to use a jdbc driver in caf

Hi, all.
     I tried to make a ws to access DB with CAF, but I had no idea how to use a jdbc driver(.jar).
    Can anyone do me a favor? Thx
    PS: my server is ce7.1

hi
If you want to interact with db tables in caf,try like this.
it may work..
Using EJB call database tables using jdbc driver.
Expose EJB as webservice.
and using External service option of caf utilise this webservice in caf,do the necessary mappings..
you can search in sdn,how to call DB tables in EJB..

When I run this class I get the following output
1, row 1
2, row 3
3, row 5
4, null
5,
But It should have been
1, row 1
2, row 2
3, row 3
4, row 4
5, row 5
The same class runs fine if I use Thin driver.
Can anyone please help me solve this issue.
Note: This happens only in case we use setString with Varchar2 in the DB. This works fine if I have two number columns

Problems showing german special characters using DB2 jdbc driver

Hi JDBC gurus,
In my application the special german characters(umlauts...) are not shown correctly when I'm using IBM jdbc driver(type 2). When I switch to jdbcodbc driver everything is correct. So is there any trick, some connection parameter, some property or something like this? Something like "setCharset" or "umlauts" or something? I could not find anything in web :-(
It is also hard to imagine that nobody has faced this problem. Or it is very trivial...
The second problem:
I have downloaded a new driver (com.ibm.db2.jcc.DB2Driver) but when I try to connect with DB I'm getting
com.ibm.db2.jcc.b.SqlException: No license present. What does it mean - no license? I'm going to clear with our DB admin if the reason can be that I have no rights to connect directly with DB without having client installed locally on my PC. This is only what comes to my mind.
Environment:
DB: DB2 7.x
Web-Server: Tomcat 5.x
Hibernate 3.1.x

Actually the problem is ONLY symbol � - scharfes S. Other umlauts are shown correctly...
What is wrong with that symbol????
Many thanks in advance,
Giorgi

SQL Developer 3.2 crashes with java error when using OCI/Thick Driver

I just installed SQL Developer 3.2 on my linux desktop. SQL Developer crashes with a java error when I select a database from the object tree.
When I check Use OCI/Thick driver the application will crash when I navigate to the tree and open a database.
The app does not crash then I have Use OCI/Thick driver unchecked.
Here are some details of my environment:

I also had the problem of SQL Developer crashing when using OCI/Thick driver but I've managed to solve it. My configuration is:
- Windows 64-bit
- Java 64-bit (1.6.0.34)
- SQL Developer 3.2.09 64-bit
- OCI Instant client 11.2.0.3 64-bit (without installation).
The thing that solved the problem was copying two files, ojdbc5.jar and ojdbc6.jar, from Instant client installation folder to JAVA_HOME/lib/ext folder+.
After that, I haven't had a single crash or error message.
The same trick that solved the problem on 64-bit installation also solved the problem on another windows computer with 32-bit SQL Developer installation.

Is it supported to use Microsoft JDBC driver use in Java 7 (and 8) multithreaded applications?

Hello everone
is it supported to use Microsoft JDBC driver (the latest version) with Java 7 multithreaded application?
I am planning to use standard Java 7 threads library and use separate JDBC objects per each thread, i.e. Java threads will not share any JDBC objects among them, only the thread-safe Java collections/data structures will be shared between threads (such as
ConcurrentHashMap etc). The JDBC connections, resultsets, statements, etc will be created and dedicated per each individual thread.
If it is supported - do you expect this design to scale-up well or am I better off using multiple but single-threaded Java/JBDC programs to access SQL Server 2012/2014 from Microsoft JDBC driver?
Thanks

Yes, so long as:
> Java threads will not share any JDBC objects among them,
>do you expect this design to scale-up well or am I better off using multiple but single-threaded Java/JBDC programs >to access SQL Server 2012/2014 from Microsoft JDBC driver?
Using threads should scale better than using processes (at least on Windows), as there is quite a bit of overhead with a process. Each process has it's own JRE, it's own GC heap, its own threads...
The bigger question, though, is how this scales on the SQL Server. Your throughput may be limited by resources on your database server, and the thread's workloads may not be able to run concurrently because of locking.

What are the benefits to using the OCI JDBC driver?

I understand that the Thin JDBC driver is geared toward Applets since it is all Java and relatively small for download. If I am running servlets is there any compelling reason for me to use the OCI driver? I would think my application would be more portable if I stuck with the Thin driver even on the server side. This would allow me to easily move my servlet application to UNIX from NT, Java Web Server to IIS, IIS to Apache... So, does anyone know what one would gain by maintaining the Oracle Client software on the server and using the OCI driver?
Thanks in advance.

It's not a separate account. It's simply an additional address on your existing account and you can use it or not use it at your own convenience. Your @me.com address will be unaffected.

Hi. I don't see our code anywhere in the stacktrace, but I'll assume
it's there somewhere. The basic fact is that our MS SQLServer driver
implements practically zero of the JDBC 2.0 methods. There is a way
to connect to this driver that has the methods defined, but then all
the difference will be that you'll get an exception saying 'this jdbc 2.0
method not implemented'.

Hi,
For OPTIONAL support in 11.1.0.7.0, you need the following patch
Patch 7600122: CURLY BRACE SYNTAX,VIRTUAL MODELS, NETWORK INDEXES AND HINTO FRAMEWORK SUPPORT
Support for SPARQL FILTERs in SEM_MATCH is not available for 11.1.0.7.0. You will need version 11.2.0.1.0 or later for FILTER support. With 11.2.0.1.0, we recommend that you apply our latest patch set:
Patch 9819833: SEMANTIC TECHNOLOGIES 11G R2 FIX BUNDLE 2
All of the above patches are available through My Oracle Support.

Connecting to SQLserver 2005 via Web Analysis using a JDBC driver

We are currently working on a web analysis suite and have been trying to create a SQL spreadsheet data object.
After downloading and supposedly installing the sqljdbc.jar driver, we are having problems getting a connection to MS SQL server 2005.
We set the classpath to this driver in the operating system (Windows server 2003) but are unsure exactly how to set this classpath in Tomcat 5.0.28 as recommended by the help file. We have tried editing the catalina.bat and catalina.50.bat in the \Hyperion\common\appServers\Tomcat\5.0.28\bin folder to point to sqljdbc.jar, but to no avail.
So....does anyone have any experience on setting up the JDBC driver for MSSQLServer 2005 and making a connection in Web Analysis. Could you please give a step by step account of how this is done?

Hi,
In the past I have used two methods either updating the registry for the web application or by placing the jar file in the following directory
\Hyperion\deployments\Tomcat5\WebAnalysis\webapps\WebAnalysis\WEB-INF\lib
If you do place it in that directory you will need to restart the web analysis web server.
Then in web analysis studio go to file > new > database connection >Relational
Select Microsoft SQL Server
JDBC Driver
com.microsoft.jdbc.sqlserver.SQLServerDriver
Connection string
jdbc:microsoft:sqlserver://<servername>:1433;DatabaseName=<dbname>;SelectMethod=cursor
Enter username/password
There is always the Merant SQL server connection that can be used as well.
Cheers

How to use Oracle jdbc driver fixedString property?

Oracle pads values in char columns so if I insert "a" in a CHAR(2) column then I cannot get that record by comparing that column to "a", I should get it by comparing it to "a ". Right?
To solve this problem the Oracle jdbc driver has the property fixedString but I cannot make it work. (look for fixedString here )
I'm using ojdbc14.jar driver for Oracle 10gR2 and accessing an Oracle 10gR2 database.
This is my code:
try {
Properties props = new Properties();
props.put("user", "****");
props.put("password", "****");
props.put("fixedString", true);
Class.forName("oracle.jdbc.driver.OracleDriver");
String jdbcUrl = "jdbc:oracle:thin:@<host>:<port>:<sid>";
Connection connection = DriverManager.getConnection(jdbcUrl, props);
PreparedStatement ps = connection.prepareStatement(
"SELECT * FROM MY_TABLE WHERE MY_TABLE_ID = ?");
ps.setObject(1, "abc"); // (*)
// MY_TABLE_ID is CHAR(15)
ResultSet rs = ps.executeQuery();
while (rs.next())
System.out.print("data: ");
System.out.println(rs.getString("MY_TABLE_ID"));
rs.close();
ps.close();
connection.close();
} catch (SQLException ex) {
ex.printStackTrace();
} catch (ClassNotFoundException ex) {
ex.printStackTrace();
The above code executes fine (no exceptions thrown) but the ResultSet is empty after executeQuery().
If I change the line (*) for
ps.setObject(1, "abc ");
Then I get the column I wanted. So it seems the driver is ignoring the fixedString option.
I've also tried changing the line (*) for
ps.setObject(1, "abc", java.sql.Types.CHAR);
But the ResultSet I get is empty again. What am I missing?
Thanks in advance

Es un Bug se corrige en la versión del OAS 10.1.2.3

Cant get OCI jdbc driver working on Mac OS X

I have installed the 10g final release for Mac OS X 10.3.7.
I did a custom install...ONLY the JDBC drivers...nothing else.
I have gotten the THIN driver to work fine and connect to the database. But when I try to use the OCI driver, I keep getting unsatisifed link errors. I have set my LD_LIBRARY_PATH and such but no luck. Anyone got any ideas for what I need to do?
Environment vars:
