JDBC Configuration

Hi All,
How can I configure Connection Pool for the following case :
1. Machine IOTA has weblogic Server 6.1 installed on Windows 2000
2. Machine COSTEL has ORACLE installed on windows NT with default database
name as SANSKRUT
What all i have to do for accessing database on COSTEL from a JSP page using
DataSource deployed on IOTA ?
I want to use Weblogic jDriver for Oracle.
I have done :
1. Connection Pool :
Name costelPool
Targets myserver
URL jdbc:weblogic:oracle
DriverClassname weblogic.jdbc.oci.Driver
Initial Capacity 0
MaxCapacity 5
CapacityIncrement 1
Properties user=scott;password=tiger; server=localdb >>>>>
shall I hvae to give COSTEL here ?
if not where i have to mention the COSTEL AND THE DATABASE NAME IN
CONNECTION POOL ?
2. Set up Datasource using the above connection pool
Thanks in advance.

JCA / JDBC Configured for non-XA Attempting XA Transaction Commit

I am attempting to create simple BPEL SOA composites in SOA 11.1.1.5 that use a DbAdapter to execute a stored procedure in an 11g database. The database task being performed only involves a single database and does not require transaction support. I have carefully stepped through the creation of the DataSource and JCA pointing through the DbAdapter to the JDBC DataSource so XA transaction support is disabled, the JCA pool sets the transaction mode to "No transaction" and the JCA pool uses the dataSource value to point to the JNDI name of the JDBC pool rather than the xADataSource value.
Visually,
DataSource definition:
name = jdbc/myserviceDataSource
driver = oracle.jdbc.xa.client.OracleXADataSource
url = jdbc:oracle:thin:@mydbhost.myfirm.com:1521:GENERIC
use XA DataSource = unchecked
set XA timeout = unchecked
Keep XA connection until transaction complete = checked
keep connection after local transaction = checked
JCA definition:
name = eis/DB/myserviceDataSource
dataSourceName = jdbc/myserviceDataSource
xADataSourceName = (blank)
platform class name = org.eclipse.persistence.platform.database.Oracle10Platform
Transaction | Transaction Support: no transaction
This configuration works on one sandbox server and I got it working in a second sandbox server. However, after deleting the JDBC and JCA pools to go through the process one more time to document the procedure on the second server, I am unable to get the configuration working again. The WebLogic domain appears to be resurrecting portions of an old configuration that still references the JNDI name of the JDBC pool in the xADataSourceName parameter. I have unpacked the DbAdapter.rar archive for the DbAdapter and verified the contents of the ./META-INF/weblogic-ra.xml file don't use the xADataSouceName parameter. The Deployment Plan for the DbAdapter (named DbAdapterPlan.xml in $SOA_HOME/soa/connectors ) also explicitly configures the JCA pool using the dataSourceName value leaving the xADataSourceName value blank.
However, executing the SOA service using this JCA connection results in this error:
java.sql.SQLException: Cannot call Connection.commit in distributed transaction.
Again, I know the theoretical answer to this question is to disable transactions in the JCA and JDBC configurations and don't use the xADataSourceName element of the JCA configuration to point to the JDBC pool. However, after validating those elements and restarting the pools or performing an Update on the DbAdapter deployment, WebLogic seems to still create connections through the JDBC pool with transactions enabled.
Any suggestions?
Should I just completely undeploy the DbAdapter and redeploy it from the SOA binary installation directory? These are just lab machines right now so that's obviously not a good long term answer for production use but may help start over with refining a better procedure for doing this.

You should use a non-xa driver for your data source...
From the weblogic docs...
Configure Transaction Options
When you configure a JDBC data source using the Administration Console, WebLogic Server automatically selects specific transaction options based on the type of JDBC driver:
For XA drivers, the system automatically selects the Two-Phase Commit protocol for global transaction processing.
For non-XA drivers, local transactions are supported by definition, and WebLogic Server offers the following options ...

JDBC configuration in 9.2.0.1

Hi,
In trying to use JDBC xa semantics in 9.2.0.1 i get a Resource Manager error during a xaresource.start(). Our Oracle configuration is customized in that we don't package components that are not needed. (We just need the database, jdbc and replication)
If i install 9.2.0.1 from the Oracle supplied CD it works fine.
What are the things i need to look at for JDBC configuration?
I have looked at the ojdbc14.jar, the shared lib for OCI driver and some init.ora parameters like java_shared_pool.
They are similar in both configurations.
Any help appreciated.

Oracle 9i JDBC configuration failure?

I am testing some Java servlet (run over tomcat container) which needs to access the Oracle DB installed on the same Solaris server.
It works well with Oracle 8i, and we then install the program on another Oracle 9i server.
when we set up the DB and use SQL *Plus to access the DB it works-- and when running netstat on Solaris-- the port 1521 is not open-- that is the default port for JDBC, and it should be open.
My java program shows the following error
java.sql.SQLException
: Io exception: The Network Adapter could not establish the connection
As port 1521 is not open at all so the servlet running on the same machine can't access it.
Could you kindly help give advice --- on 9i, how shall I check the setting to make sure JDBC is well configured and ready for use? A thousand thanks

Hi Li,
You don't have to do a netstat to check for the port. Use the lsnrctl utility. Its found in ORACLE_HOME/bin directory.
Listener is the program which recieves all the requests to database and sends it to Oracle for processing, and returns the results back.
$lsnrctl status
-- this will show if the Listener is running or not
$lsnrctl start
-- this will start the listener in the port specified in ORACLE_HOME/network/admin/listener.ora
$lsnrctl stop
-- stop the listener
If your listener is not running, start the listener and try connecting.
If your listener is not running, then you cann't connect even using sqlplus.

Production server JDBC configuration

Anybody knows what is the way to configure the JDBC pooling parameters such as init & max capacity

QiuAnd how is the pool used? Generated EJBs or hand-written JDBC?
Will every user of WebLogic need pool access?
Typically a user will want one pool connection per invoke,
and typically the connection is reserved, used, and returned
to the pool during each server-invoke from a user. However, no
matter how many concurrent users there may be, the server only
has a set number of threads that will handle user calls, so
the pool ideally needs only N connections for an N-thread server.
If you have a refresh time set for the pool (so it asynchronously
tests idle connections) add 1.
I would have the pool make all the connections at startup,
so I would recommend initial capacity = max capacity = (N + 1).
I would have test-on-reserve true, and no other testing. I
would set the statement cache to hold all the prepared statements
the application would use, and for Oracle I would make sure the
DBMS is configured to allow a connection to have as many cursors
as the statement cache would require, at least. If performance
was tested and found to be necessarily better with test-on-reserve
false, I would consider using the new secondsToTrustAnIdlePoolConnection
to allow test-on-reserve to go back to true, but skip some testing
with recently used connections. Thsi depends on how tolerant the application
might be to occasionally getting a bad connection and how reliable the
DBMS is etc.

Problems with jdbc configuration in the config.cfg file

Hi to all,
I need to change my oracle database ucm user from idc_orcl to idc_oracle for example but i dont know how to generate the encrypted password of the user in the config.cfg file
if I let the configuration like below (plain text password and JdbcPassword commnetend) it works.
But it is not an accepted solution for me, leaving the password in plain text.
+#Database Variables+
JdbcDriver=oracle.jdbc.OracleDriver
JdbcConnectionString=jdbc:oracle:thin:@localhost:1521:ucm
JdbcUser=idc_oracle
JdbcPassword=idc_oracle

Hi,
I'm not sure what the problem is, but I can give you some basic suggestions about what you could do.
First of all, check if there are more detailed error messages available in the defaultTrace.trc file. You can open the file using LogViewer service in Visual Administrator.
Also, check the settings for Database URL, and make sure you have set the SQL Engine option in the Additional tab to "Native SQL".

JDBC Configuration with Multi Datasource

Hi all,
We're using Weblogic 9.2 and has configured Multi Datasource with Failover algorithm. All is working well, but our DBA has reported that some requests were randomly still going to the 2nd node although he was sure that nothing was wrong with the 1st node. Is this an expected behavior with the Failover algorithm.
Any help would be greatly appreciated.
Thanks & Regards,
Besetya

Some of the application-level work? I think you can configure an MDS to 'fail over' if the first pool is
simply at capacity and unable to deliver another connection. You can check that, and make sure the
first pool is big enough. Than, also configure the backup pool with an initial capacity of 0, so it
never even makes a connection unless the MDS fails over to it.

I don't understand. Why not simply adjust the date for the desired time zone or adjust it when you display it (if that's a better solution). I cannot be sure of the best way for you to solve this as I know nothing about your project.

Help: Connecting Tomcat to CA-IDMS Using JDBC Type 4 Drivers (JNDI)

Hi there,
I have a rather interesting / complex problem......creating a connection to CA-IDMS from Tomcat using JDBC type 4 drivers (CA provide the type 4 driver).
We have a zSeries 9 IBM mainframe running CA-IDMS r16.1, and I need to connect to the IDMS from Tomcat (running on Linux) using the JDBC Type 4 drivers provided by CA.
At this stage I am struggling with the actual setup and configuration of Tomcats server.xml and web.xml files. These are the files where the JDBC configuration is set (I think). I have to setup the CA-IDMS part of the configuration, but that is a different problem. Basically there is a TCP/IP listener on the IDMS, waiting for incoming connections from the JDBC type 4 driver.
I set up a Tomcat to MySQL connection using MySQL Connector / J, which is a similar kind of process to what I am trying to achieve with IDMS. MySQL connector / J came with a jar file which is placed in Tomcats lib folder, and then the JDBC setup for the web application is created in Tomcat's server.xml and web.xml files. You can then connect to the MySQL database using JSP and the configured JDBC driver / connection. The CA-IDMS Server comes with an idmsjdbc.jar file, which I think is the JDBC typr 4 driver. I think it needs to be placed in the Tomcat /lib folder, but I dont know how to set up the configuration.
There is a JDBC DriverManager which allows JDBC drivers to connect to CA-IDMS. The DriverManager recognises the following syntax:
jdbc:idms://hostname:port/database
This allows the JDBC driver running within Tomcat to connect to the IDMS which is running on the IDM mainframe. CA IDMS r16 supports direct connections from the Type 4 JDBC driver to the Central Version on IDMS. "hostname" is the DNS name or IP address of the machine where the CV is running, and "port" is the IP port that was specified for the listener PTERM (setup on the IDMS side).
There is a caidms.properties file for the JDBC driver, which is used to specify user ID, password, and optional accounting information. It can also be used to specify physical connection information, allowing an application to connect to a CA-IDMS database without requiring the definition of an ODBC style data source. However, I dont know where to place this file within the Tomcat setup.
There is also an IdmsDataSource class. I dont know where to configure this or how to set it up; the CA-IDMS Server manual states the following:
This class implements the JDBC DataSource interface. It is used with an application server (Tomcat) providing Java Naming and Directory Interface (JNDI) naming service to establish a connection to a CA IDMS database. IdmsDataSource properties conform to the Java Beans naming conventions and are implicitly defined by public setter and getter methods. For example, the description property, which is required for all DataSource implementations, is set using the setDescription(String) method. The application server may use the java.lang.reflection methods to discover DataSource properties and provide an interface to set them, or may simply require that they are defined in some configuration file. IdmsDataSource properties are used to specify the connection parameters. These properties are the equivalent of the DriverPropertyInfo attributes described in the previous section and can be used to completely define the parameters needed to connect to a database. Like a URL, an IdmsDataSource object can also reference an ODBC style data source name, where the connection parameters are defined in the configuration file on Linux.
Is there anyone that can try to point me in the right direction to setting up the JDBC connection? I am totally new to Java and so the instructions are not making much sense at the moment. Any help, hints, tips..anything will be greatly appreciated as I have just hit a brick wall here. I can't find much to do with setting up the CA-IDMS Server JDBC type 4 driver online either....if anyone can point me to some resources that would also be extremely useful.
Kind regards
Jp

You say you've managed to get the JDBC driver working
in an application but not in a JSP. You also say that
the error you get is
"com.microsoft.jdbc.sqlserver.SQLServerDriver".
I'd be willing to bet that the exception that you have
got is a ClassNotFoundException. I.E. your application
server hasn't found the JDBC driver classes. The
application server probably doesn't use your current
CLASSPATH to look for classes. It will be setup within
the application server in some way and you'll need to
check your app server documentation to see how it is
done.
Try replacing
e.printStackTrace();with
e.printStackTrace(out);to get a full stack trace of your error.
ColTried it. Got this error when I tried to run the JSP.
Incompatible type for method. Can't convert javax.servlet.jsp.JspWriter to java.io.PrintWriter.
e.printStackTrace(out);
I'm currently using Apache Tomcat 4.0.3 as my JSP/Servlet Container.
I'm also using Type 4 MS SQL Server 2000 JDBC driver version 2.0 on my NT4.0 Server.
Do I need to set my JDBC driver in my container? if so, how do I do that?

SAP R/3 -- PI -- Oracle DB SYNC (JDBC)

What is the best approach to handle the following request:
We need to develop a synchonous call that will pass information from SAP R/3 through PI to an Oracle database can return the data.
For instance, we want to pass a material number from SAP R./3, and have all the related information stored in the Oracle DB returned immediately.
The data stored in Oracle will be retrieved via a JDBC connection. If possible can you provide an example....thx

>> Just a simple query, no updating is required.
>>> select f1 f2 f3....from ms_tbl where part = inbound-part
Then you dont need sql stored procedure . We can easily handle at pi side.
Step 1) create data type for proxy as per your need
Step 2) Create the data type for jdbc request side as similar below ...
<stmt>
 <Customers action="SQL_QUERY">
 <access> SELECT f1,f2,f3 from ms_tbl WHERE PART ='$KEYFIELD$';</access>
 <key>
 <KEYFIELD>inbound-part</KEYFIELD>
 </key>
 </Customers>
</stmt>
Note: use constant to populate values for action and access field in mapping area.
Step 3)
create data type for the jdbc response side as below
<stmt_response>
<row>
<f1>
<f2>
<f3>
</row>
</stmt_response>
Step 4)
Then create Proxy response data type
Step 5) create message types and Service Interface.(outbound synchronous and inbound synchronous)
step 6)first map: Map step 1 messg type with step2 mesg type
step 7) second map: Map step 3 mesg type to step 4 mesg type
Integration Directory: configure Jdbc reciever. Rest are all same.
That's it.
