JDBC in WebLogic setting

Hi all,
I would like to ask what should I set in the Connection Pool in Weblogic if I want to connect to the database?
For example, the JDBC COnnection Pool in the console, it has Name, URL, Driver Classname, Properties, ACLName, Password, Open String Pasword. I don't know set which values in these attributes. I am use Oracle 9i as the database.
Does anyone could give me some hints about it?
Thanks!!

Add the path-names for the WebLogic shared library (.dll) directory WL_HOME\server\bin\oci901_8, and the Oracle client library,ORACLE_HOME\bin to the PATH variable.
Add ORACLE_HOME\JDBC\lib\classes12.zip file containing the Oracle JDBC driver classes to the CLASSPATH variable.
URL: jdbc:weblogic:oracle
Driver Classname:weblogic.jdbc.oci.Driver
In the Properties field:
user=<user>
password=<password>
server=<database>
user, passowrd is the user, password to login to the Oracle database.
database is the Oracle database name.

How does jdbc fetch a set of records in oracle

Hi,
Oracle does not support server side cursors,if so how does jdbc fetch a set of records(set by setFetchSize(), which is 10 by default) each time I say rs.next().Does this mean Query is re-executed to fetch the next set of records? Can some body throw some light on this?
thanx in advance
Gnayan

You are asking about implementation details of some JDBC driver, but you don't say which one. This makes it very difficult to answer your question. You might want to try asking the question of the people who wrote the driver.

Does weblogic set socket buffer size ?

Hi all,
Want to know if Weblogic sets the Socket buffer size,when it establishes a connection with a client ?
If so then what is its default value?
any help is appreciated.
Thanks in advance.

Thanks for all your reply.
I give u more detail on my issue:
Test Environment:
Server: 4 GB memory, 1.3 GHz, a dual core CPU with hyper-threading enabled on each core (4 logical CPUs), a tomcat with my application deployed
Client: the same configuration as Server, a http simulator
Network: 1Gb/s
Test:
1> Simulate one user. Client keep sending requests to server, and server has one thread serve user's requests. (make Server always busy)
request
Server <------------- Client
response
Server ---------------> Client
request
Server <-------------- Client
CPU usage was 18%, in normal case should be 25% (100% / 4 = 25%, in my other cases, CPU were 25%)
Take a few thread dumps: saw threads sometimes blocked in the native method java.net.SocketOutputStream.socketWrite0(Native Method).
2> Simulate 4 concurrent users. Client keep sending requests to server concurrently, and server has multiple threads serve user's requests. (make Server always busy)
4 requests
Server <------------- Client
responses
Server ---------------> Client
requests
Server <-------------- Client
CPU usage was 80%, in normal case should be 90%+.
Take a few thread dumps: saw threads sometimes blocked in the native method java.net.SocketOutputStream.socketWrite0(Native Method).
If CPU was not fully utilized, for example only 80%, server must be blocked by something. And this bottleneck would impact the scalability of server.
If I can remove this bottleneck and do not bring other overheads, I may acquire:
1> a higher throughput
2> a more scalable server
In our performance requirement, server CPU usage must be 90%+.
I just feel strange that why the CPU usage was normal (25% for single thread test or 90%+ for 4 threads test) even I choose a very small buffer size.

Error got while creating a jdbc in Weblogic server 9.2

Hi All,
I am getting the following error
+"Warning! Connectivity to backend database not verified. This is either because required connection pool attributes "TestConnectionsOnReserve" or "TestConnectionsOnRelease" have not been enabled, or an invalid value has been specified for attribute "TestTableName". Please check the server log for more details".+
While creating a jdbc datasource in Weblogic 9.2. When I add the target and activate the setting and while testing only I am getting this error. While before adding target "Test connection" works good.
Please help me in fixing this bug.
Thank you in Advance.

Weblogic setting the Oracle password

Hi,
I have a problem with an Oracle 8.1.7 database and Weblogic Server 6.0 sp2 both
running on an HPUX 11 Unix box in that everytime I start Weblogic it sets the
Oracle password to be the value of the Orarcle sid. I have configured Weblogic
to have a Connection Pool to the database.
Anyone have any clues?

Weblogic setting Cache-control: no-cache?

I have a servlet filter that sets the Cache-control http header to "max-age=30" for static files such as *.css but in the end weblogic sends the value "no-cache".
When the browser asks for the same static file again weblogic responds with http 304 and Cache-control "max-age=0" thus overriding my filter again.
Is there any way to change the client side caching in weblogic (10.3.4)?
(btw the servlet filter works in tomcat)

Hi,
1. response.setHeader("Cache-Control","no-cache");
This is used to prevent the browser from caching your dynamic content generated by a JSP or Servlet.
You set this attribute in the HTTP header of the response object which would tell the browser not to cache this content. So everytime you request the page again, the browser would make a new request, instead of showing you a cached page.
2. response.setHeader("Location", "error.html");
This is called redirecting. "Redirecting" is sending a response from your servlet to the browser telling the browser to go to a new location(make a new request)
The standard way to do this response.sendRedirect(String);

JDBC and character set convert issue

Hi All,
For some special Chinese characters, we will have the "ORA-00933: SQL command not properly ended" error when we try to insert the data into a Oracle ASCII DB. I have been tried to use the "HasQuot='no'" in the tag and the "N'xxxx'" in the data field but we still got the error.
Do anyone have the idea about it?
Best Regard

It is possilbe to store Big5 code in ASCII DB since it is one kind of ASCII code too.
If the locale or code page on client is Big5 or 950(MS windows) then the data can be shown properly.
We tried many ways to store Big5 code in ASCII DB by using PI in these days but failed.
The following are the things that I have tried.
1. enable "hasQuot" with "no" or "No" constant in attribute; set the data as format N'xxxx' : still got ORA-00933.
2. enable AF_Modules/XMLAnonymizerBean befer and after CallSapAdapter module: for some special characters it still has )RA-00933; even we insert the data into DB successfully, we can not process the response properly.
3. enable AF_Modules/TextCodepageConversionBean before CallSapAdapter module: we can insert the special characters into DB if we set the parameter of Conversion.charset to ASCII. However, the Chinese character will become to "?" in DB.
I will keep trying,
Thanks all of your help.

Generic JDBC connection not setting up.

Hey ..
I am trying to make a Generic JDBC connection in DB adapter. For the steps I am refering to this blog: https://blogs.oracle.com/middleware/entry/configuring_mssql_with_soa_suite
so I went as follows: step 3 of 4 of adapter configuration > create new connection > Driver class: new > Library: Browse
chose the driver source .jar, put the correct URL & tested the connection.
The Error that came said:
"Test failed: Driver class not found.
Verify the Driver location"
I tried same thing with sqljdbc.jar - the file used in the blog ... Same error was there.
What's the mistake? What should I try to do?

The problem got solved ..
Actually the path was correct but the driver class name was wrong ..
Perhaps it tries to find the driver class with the specific name in specified .jar
I thought we are CREATING new thing ..
Thanks anyways for your help

Issues on setting the SQL ARRAY in Weblogic 10.3

Hello,
I am facing problem while migrating my application from Weblogic 8.1 to Weblogic 10, and problem is on setting the database ARRAY.
here is the brief of the problem which we are facing during weblogic upgrade, appreciate if someone could help us in this regard.
Requirement:- Upgrading the Weblogic Server from 8.1 SP4 to 10.3.
Problem Description :- We are facing issue with Weblogic server 10.3 related to JDBC call for setting the Database Array. We are using Spring framework JDBC templates.
In 8.1 we used to send the database Array by using two different methods mentioned below.
Method 1 :- First method which we are using to set the ARRAY object to database.
CODE:
public Object doBaseInConnection(Connection connection) throws SQLException
OracleCallableStatement callableStatement = OracleCallableStatement)connection.prepareCall(DBUtils.createPreparedStatementFunctionString("bbvoice_customer_discovery_ng", "validate_password_3", 8));
callableStatement.registerOutParameter(1, Types.INTEGER);
callableStatement.setString(2, identifier);
callableStatement.setString(3, password);
ArrayDescriptor arrayDesc = ArrayDescriptor.createDescriptor("TACTOSS.PRODUCT_NAME_ARRAY", connection);
ARRAY ocbsArray = new ARRAY(arrayDesc, connection, productSearchList); -- Exception in this LINE
callableStatement.setARRAY(4, ocbsArray);
callableStatement.execute();
EXCEPTION:
This was working fine in Weblogic8.1 where as giving the below exception in Weblogic 10.3.
java.lang.ClassCastException: $Proxy439 cannot be cast to oracle.jdbc.OracleConnection
at oracle.sql.ArrayDescriptor.createDescriptor(ArrayDescriptor.java:155)
at oracle.sql.ArrayDescriptor.createDescriptor(ArrayDescriptor.java:123)
CHANGE:
Only change in Weblogic 10.3 in this area is earlier in weblogic 8.1 we used to have ojdbc14.jar but weblogic10.3 is having ojdbc6.jar.
Method 2 :- Second method which we are using to set the ARRAY object to database.
CODE:
public Object doBaseInConnection(Connection connection) throws SQLException
OracleConnection oracleConnection = (OracleConnection) ((WLConnection)connection).getVendorConnection(); -- Exception in this LINE
OracleCallableStatement callableStatement = (OracleCallableStatement)connection.prepareCall(DBUtils.createPreparedStatementFunctionString("bbvoice_business_bbv_ng", "create_service_3_mb", 15));
callableStatement.registerOutParameter(1, Types.INTEGER);
callableStatement.setBigDecimal(2, new BigDecimal(customerId.intValue()));
callableStatement.setString(3,businessBBVDTONG.getCpeType() );
ArrayDescriptor arrayDesc = ArrayDescriptor.createDescriptor( "TACTOSS.GEO_DETAILS_ARRAY", oracleConnection);
List geoList = businessBBVDTONG.getGeoNumberList();
int size = geoList.size();
Object arrayValues[][] = new Object[size][];
Object[] str = new Object[3];
for(int i=0;i<geoList.size();i++)
     GeoNumberDTO geoNumberDetails = (GeoNumberDTO)geoList.get(i);
     str[0]=geoNumberDetails.getDirectoryEntry();
     str[1]=geoNumberDetails.getCssDistrictId();
     str[2]=geoNumberDetails.getCssExchangeGroupCode();
     arrayValues[i] = str;
     str = new Object[3];
ARRAY ocbsArray = new ARRAY(arrayDesc, oracleConnection, arrayValues);
callableStatement.setARRAY(4, ocbsArray);
callableStatement.execute();
EXCEPTION:
This was also working fine in Weblogic8.1 where as giving the below exception in Weblogic 10.3.
java.lang.ClassCastException: $Proxy216 cannot be cast to weblogic.jdbc.extensions.WLConnection
at com.bt.bbv.core.dao.bbvoice.nextgen.BusinessBBVDAONGImplDB$2createService.doBaseInConnection(BusinessBBVDAONGImplDB.
java:171)
at com.bt.bbv.core.util.BaseConnectionCallback.doInConnection(BaseConnectionCallback.java:38)
CHANGE:
Changes from Weblogic 8.1 to 10.3 are
1) We are not having the WLConnection in weblogic.jar instead it is present in com.bea.core.datasource6_1.4.0.0.jar
2)Weblogic 10.3 server is having ojdbc6.jar instead of ojdbc14.jar.

You'll also need to map the security role defined in web.xml to a Weblogic principal (an actual Weblogic user or a group) in weblogic.xml.
Example:
web.xml
<web-resource-collection>
<web-resource-name>PowerPointTemplates.jws</web-resource-name>
<description>A web service secured by SSL and basic authentication</description>
<url-pattern>/PowerPointTemplates.jws/*</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
</web-resource-collection>
<auth-constraint>
<role-name>Friends</role-name>
</auth-constraint>
<user-data-constraint>
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint>
</security-constraint>
<login-config>
<auth-method>CLIENT-CERT</auth-method>
<realm-name>myrealm</realm-name>
</login-config>
<security-role>
<description>Role description</description>
<role-name>Friends</role-name>
</security-role>
weblogic.xml
<security-role-assignment>
<role-name>Friends</role-name>
<principal-name>weblogic</principal-name> 
<principal-name>user1</principal-name>
<principal-name>user2</principal-name>
<principal-name>Turbo_Users</principal-name>

Major performance problem in weblogic jdbc

I ran a test which selected ~1000 rows from an oracle database table. The
code ran in 4 seconds when I used the Oracle driver directly:
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection connection = DriverManager.getConnection(URL, "XXX", "XXX");
When I changed the code to get the connection from weblogic, it took 128
SECONDS!!!!
weblogic.jdbc.connectionPool.pointclick=\
url=jdbc:oracle:thin:@XXX:dev,\
driver=oracle.jdbc.driver.OracleDriver,\
initialCapacity=1,\
maxCapacity=2,\
capacityIncrement=1,\
props=user=XXX;password=XXX
weblogic.jdbc.TXDataSource.weblogic.jdbc.jts.pointclick=pointclick
Properties properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
Context context = new InitialContext(properties);
try
DataSource dataSource = (DataSource)context.lookup(NAME);
Connection connection = dataSource.getConnection();
// if(!autoCommit)
// connection.setAutoCommit(false);
return connection;
finally
context.close();
The strangest thing is that when I used the weblogic pool, if I executed
"select column from table" it took 128 seconds, but "select * from table"
only took 32 seconds. Why would it take longer to process less data?
And more importantly, why does the weblogic connection take so damn long?
Thanks for your help.

Hey, I finally managed to get JDBC logging up and running! Had to do with
permission setting, adding the following entry to weblogic.policy:
permission java.sql.SQLPermission "setLog";
Boy are you right; JDBC logging is slow as mud! Good thing we use BMP
entity beans, so I guess I can log JDBC calls myself in the
ejbCreate/Load/Store/Remove hooks!

Seems like Weblogic can catch SQL calls much easier than we can,
especially for CMP!It is conceivable that our pool drivers (pool,jts,rmi etc) couldindependently
log SQL for debugging purposes, but we need to retain the semantics ofturning
on jdbc logging, which in any case will continue to emanate from any JDBCdriver.
In any case, we wouldn't do anything differently that DriverManager doesfor
simply writing to a file, which would be serialized by the stream anyway.

Still, it does seem rather excessive for logging to cause a 30Xslowdown.
Someone at BEA ought to take a closer look at that...Known issue, not ours.
JDBC logging collect anything logged by any JDBC driver or by anySQLException.
These all call DriverManager.println() which is class synchronized in
the
JVM,
so this will serialize most JDBC threads, and slow the server down a
lot,
independently of the disk I/O needed to grow the file.

Nice work, Charlie!
When I just connected to the pool directly, it ran fine. I am
guessing
that
the DataSource returns a connection that connects first to the
server
via
RMI and then to the database. I am trying to obtain a JDBC
connection
for
use in EJB and servlets, so this is clearly overkill. The
question I
now
have is what is the best way to obtain a transactional
connection
without
the overhead described above? Can I somehow create a
transactional
DataSource that doesn't go over RMI? Or, should I just use thejts
driver
directly? I tried the following code, but got an error:
Driver driver = new weblogic.jdbc.jts.Driver();
Properties properties = new Properties();
properties.put("connectionPoolID", "pointclick");
Connection connection = driver.connect("jdbc:weblogic:jts",properties);

Your Oracle example is also using JNDI to obtain the connection;
not
just
getting a connection from a pool. So you've actually changed 2conditions
( non-pool to pool, non-JNDI to JNDI ). So both of these should
be
considered as suspects for the performance.

SOA WebLogic : Cannot load JDBC driver class

Hi, I'm new to this Oracle SOA World. Currently I'm trying to configure environment on my system. I found a very useful document to install all related SOA component to my system, the document name was 'Quick Start Guide for Oracle® SOA Suite 11gR1 (11.1.1.5.0)'. I did all the steps written in the document and have installed all the components successfully, component including Database, Jdevelper, WebLogic Server, RCU, SOA suite, service bus, all are installed successfully.
But when I'm trying to Configure Application Server (start -> Oracle SOA 11g-Home1), at one step 'Configure JDBC Component Schema' , here I'm getting this message

In addition, when i just ignore this message and continue installation, after installation when i run weblogic server then it gives error and gets terminated

Hi:
try placing the jars that represent ur driver, here
For both Windows and Linux, you must perform the following steps:
Drop the vendor-specific driver JAR files to the user_projects/domains/soainfra/lib directory.
Drop the vendor-specific driver JAR files to the <Weblogic_Home>/server/lib.
Edit the classpath to include the vendor-specific jar file in <Weblogic_HOME>/common/bin/commEnv.sh
This info was copied, from here: http://docs.oracle.com/cd/E21764_01/integration.1111/e10231/adptr_db.htm#CHDBEJDC
Hope this helps
best

Hi ALL,
I have an requirement to enable SSL Mechanism in weblogic JDBC Connection Pool.we are using Oracle9i Enterprise Edition Release 9.2.0.7.0 - 64bit Production and Driver as "jdbc:oracle:thin@..." / oracle.jdbc.OracleDriver.
weblogic server 8.1 SP4
can anybody know what are the steps / configuration has to be done for enable Oracle Advanced Security encryption on the JDBC Oracle Thin driver with a WebLogic JDBC Connection Pool.
Thanks,
Karthik,

Hi,
I changed the code as given below. Still getting the same error. Can I migrate my question to jdbc section? I am new to this forum.
import java.sql.*;
public class jdbc {
public static void main(String[] args) throws ClassNotFoundException, SQLException
Class.forName("oracle.jdbc.driver.OracleDriver");
String url = "jdbc:oracle:thin:@localhost:1521:xe";
Connection conn =
DriverManager.getConnection(url,"jestin","jj");
conn.setAutoCommit(false);
Statement stmt = conn.createStatement();
ResultSet rset =
stmt.executeQuery("select BANNER from SYS.V_$VERSION");
while (rset.next()) {
System.out.println (rset.getString(1));
stmt.close();
System.out.println ("Ok.");

Is it possible to set JDBC Driver CharacterSet

HI,
I'm trying to learn how the data conversion is being handled in oracle (ii.e, I wanted to check the behaviour by keeping orai18n.jar & removing it). My database character set is WE8ISO8859P1, and I would like to change different client side character sets & do some R&D related to my application.
So I want to know ....
->if we can set JDBC Driver Character set in any way.
->Is setting client character set is what is setting driver character set??
We are using Oracle 10g and getting connections using Datsource. When I try to get the driver character set using oracle.jdbc.driver.OracleConnection.getJdbcCsId(), it returns 31 (which is WE8ISO8859P1).But I didn't find any setter..or similar method.
I'm new to this Globalization thing.... so sorry if I'm asking dumb questions.... Could any one help me in this regard?? .
Thanks,

JDBC is not designed to support the notion of a driver character set. Any text data should be retrieved using ResultSet.getString() method and passed to the database using PreparedStatement.setString() method - except for CLOBs, which also accept Unicode character streams. These methods expect string data in Java Unicode encoding (UTF-16). If you need to output this data from an application is some other encoding, you should use standard Java conversion mechanisms - e.g. String.getBytes(charset) or new PrintWriter(file,charset).
The driver character set is an internal setting relevant for intermediate character set conversions between the driver and the database. It is determined automatically by the driver based on the database character set. The method oracle.jdbc.driver.OracleConnection.getJdbcCsId() is undocumented and should not be used.

Jbuilder & weblogic.jdbc.mssqlserver4.Driver

I use jbuilder8 and jdbc driver " weblogic.jdbc.mssqlserver4.Driver " to connect mssql2000..
when I use database pilot of jbuilder8 to setup a datasource..
I got an error Error " connecting to database: java.lang.NoClassDefFoundError: weblogic/version "
what should I do now ?..

Do you have weblogic.jar in your CLASSPATH?
