Oracle 9.2 connection pooling - need example

Using Oracle 9.2 and Glassfish V2 application server.
The Oracle driver library I am using is ojdbc14_g.jar
I need to convert my web application to use a connection pool rather than a fixed connection.
Databases are not my forte. Connection pools are new to me and I am somewhat confused
on what I have seen so far.
I managed to find an example that I thought would easy to implement in this article:
[http://www.rgagnon.com/javadetails/java-0545.html]
However I ended up with several unresolved references at the following lines:
import oracle.jdbc.pool.OracleConnectionCacheManager;
ods.setConnectionCachingEnabled(true);
ods.setConnectionCacheName(CACHE_NAME);
ods.setConnectionCacheProperties(cacheProps);
ods.close();
This leads me to suspect that I do not have the correct library.
So I am back to where I started.
What I am looking for is an example of how to create and implement a connection pool for my environment
or else some hints on how I can modify the code from the above article to work with my library.
Thanks.

Yes, I did a Google search, that is where I got the reference that I posted.
If I found anything that I could have used, I would have.
The problem is that the stuff I found on the search either does not work in my enviroment
or else I do not undserstand how to use it.
That is why I posted to this forum.
I was hoping that someone here has done this and could give me some help.

Oracle Application server connection pool and database links

I am using Oracle application server 10g with connection pools, the db used by the application connects to another oracle db using a database link. My question is when the application starts it creates 10 connections, does it also create x amount of database links as well?

Hi,
Is there any way to use the connection pool or Datasource while connecting to database?If I am using a stateless sesssion bean and using a Data Access layer which just creates a database session to write the persistence toplink objects how I can make use of application server connection pool?Hi Vinod,
Yes, TopLink allows you to use the app server's connection pooling and transaction services. Chapter 2 of the Oracle9iAS TopLink Foundation Library Guide provides details as do the TopLink examples. The easiest way to set this up is by using the sessions.xml file. The sample XML below is from the file <toplink903>\examples\ias\examples\ejb\sessionbean\sessions.xml. Here we are adding the datasource defined in OC4J and specifying that we are using the OC4J transaction controller also.
<login>
<user-name>sa</user-name>
<password></password>
<datasource>java:comp/env/jdbc/ejbJTSDataSource</datasource>
<uses-external-transaction-controller>true</uses-external-transaction-controller>
<uses-external-connection-pool>true</uses-external-connection-pool>
</login>
<external-transaction-controller-class>oracle.toplink.jts.oracle9i.Oracle9iJTSExternalTransactionController</external-transaction-controller-class>
When using this approach you need to change your TopLink code slightly in the EJB methods:
a. Acquire the ACTIVE unit of work from the server
session (again, see the EmployeeSessionEJB code
example) with something like:
UnitOfWork uow = clientSession.getActiveUnitOfWork();
b. Calls to uow.commit() can be ommitted or commented out
because the EJB will handle this. Note that of course
the methods you create in the EJB that are using this
approach must have TX Required (default).
Hope this helps.

Oracle Clobs, datasources, connection pools, RMI ...

Hello all,
We are using Weblogic 7.0, windows 2K server, Oracle 9i and are trying to read from a clob. Using
Weblogic datasources to manage connection pools. We are getting back a weblogic.jdbc.rmi.serialClob
object.
Any help reading data from this?
The main error is "No Data Found".
What else might I tell you to help?
Thanks a bunch for any help.
BTW
We had this working in iplanet and we are converting to weblogic. This is our last major hurdle.

Oracle Database Server 9i supports the usage of LABELS to enforce highly

I haven't seen a similar ability for BEA Weblogic Server 8.1 which allow

possible?
Have I missed an important document?
Thanks for any input,

I think there is a section in the JDBC documentation for 8.1 which
describes what it takes to utilize Oracle 9i extension called "Virtual
Private Database". With this extension, one might be able to proxy the
callers
identity to the DB.

Yes, Oracle JDBC drivers do support connection pooling. Download the latest drivers to get samples and refer doc for more details.

Does connection pool needs to be synchronized

I have a PooledConnection connectionPool created in servlet's init() method. connectionPool is a servlet instance variable.
In servlet's doGet() method, I get connection from the connection pool by "conn = connectionPool.getConnection()".
PooledConnection.getConnection() is not a synchronized method. I wonder in this case do I need to do "conn = connectionPool.getConnection()" in a synchronized block?
Thanks for your reply in advance.

A more appropriate senario is like following. Does "ds.getConnection()" need to be synchronized in doGet()? The java standard API does not specify DataSource.getConnection() as a thread safe method. Your idea is highly appreicated.
public class MyServlet extends HTTPServelet
DataSource ds;
public void init(ServletConfig config) throws ServletException
//get datasource
ds = (DataSource)ic.lookup(dsName);
public void doGet(HttpServletRequest request,
HttpServletResponse response)
//get database connection
Connection conn;
conn = ds.getConnection(); //does it need to be synchronized?
}

How to use insert row with BLOB to Oracle when use connection pool?

Have you defined
OutputStream dbBlobOut
as weblogic.jdbc.vendor.oralce.OracleThinBlob?

Creating jdbc connection pool in weblogic 8.x server using oracle database

Hi
i am having oracle 9.2.0 and weblogic 8.1. i am new to oracle and jdbc connection pool. can any one explain how to make connection pool in weblogic.
what will be the host name, port number??
can any one explain
regards,
sekar.r

The host name is the name or IP address of the machine running Oracle.
The port number is the port the DBMS is listening on for connection requests.

Physical Tables from multiple connection pools

Hi all,
we have in our RPD file two connection pools (let's say A and B), each connecting to a different source DBs.
Thus, each physical table resides either in source DB A or B (xor).
The specified connections work in Admin tool, and also direct database requests work in OBIEE 11G if we explicitly
provide the correct connection pool. The connection pools are specified in order A,B in the Admin tool.
However, using OBIEE answers always results in following error message if data from the connection pool B
is to be queried:
Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000]
[nQSError: 10058] A general error has occurred.
[nQSError: 43113] Message returned from OBIS.
[nQSError: 17001] Oracle Error code: 942, message: ORA-00942: table or view does not exist at OCI call OCIStmtExecute.
[nQSError: 17010] SQL statement preparation failed. (HY000)
If we exchange the order of connection pools to B,A in Admin tool, we get the same error if we query
data from connection pool A.
It seems that each connection pool needs to be able to access all physical tables. Is that correct?
Thanks, Thomas

Connection Pool hangs

Hello,
We have a strange problem with Oracle Connetion pool on IAS 10.1.3.1.0.
Sometimes (for example once a week, sometimes one a month) connection pool hangs. Enterprise Manager / Connection pool monitor page shows information about threads waiting for connection (see below) and users are unable to work with application.
Connections In Use                1
Free Connections                13
Total Connections in Pool           14
Threads Waiting for Connections      534
WebApp installed on IAS is a simple Toplink based application. There are no strange messages in error logs, so why connection pool is unable to assign free connection to user ?
Thanks in advance
Tom
Edited by: olos on Sep 30, 2008 8:57 PM

Hello,
Thanks for response. I will try if it is possible to test connection from AS control during next connection pool crash. BTW we must check if this situation is not caused by operation system (Linux) swapping process.

Tom

Java Connection Pooling

I want to know what is the procedure of getting oracle's jdbc connection pooling api(class files and java doc).
I also want to know whether it is free or not

ftp://javaexchange.com/javaexchange/DbConnectionBroker1.0.13.tar
from http://javaexchange.com/ by Mark Mnich
Initialise the pool in a startupservlet, place a reference to it in the servlet context (ServletContext.setAttribute(String name, Object myDbPool))
This one is really easy to use and very efficient indeed (endorsed by author David Harms).
It doesn't support multiple databases.
Maybe two pools would be just as effective? The whole point of a connection pool is that the connections within it are constantly open... so you would still have (for example) 25 connections to one database and 25 to the other - constantly. Making unused connections disconnect and connect to the other database would defeat the point, each servlet instance may as well establish its own connection So why not have two pools???

Implementing Connection Pooling - WEB app

Hi, I'm developing an application using tomcat as my server and the MVC model.
I need to use connection pooling and I don't know how to do it... does anyone know how??? is there a manual or something? please, I really need help...

Go to Jakarta's site, Commons project, download DBCP (database connection pool). Examples on the site. The only 'hard' part is setting up your JNDI entries for your J2EE container. But that is only difficult the first time you ever write a JNDI entry. After that, they are all very similar.
Depending on your RDBMS, the vendor may also offer a connection pool, such as OracleConnectionPool.

I have the whole application up and running fine on a WIN2000 platform with its own

This leads me to think this is a TNS related problem as I cant think of anything
else !.
Any help greatly appreciated...!

Hi Martin,
Using oracles Advanced Security Options can cause this, comment security
related lines out of your "sqlnet.ora" they generally have the words,
ENCRYPTION or CRYPTO in them.
Also try to set ORACLE_SID environment variable, like in the server startup
script.
ORACLE_SID=<SID_NAME>
export ORACLE_SID
Try it and see if it works. This is purely an Oracle issue not WebLogic
related. Try to contact Oracle support if you cannot resolve the issue with
above steps. You may have to reinstall the Client.

I can create a normal (non-X/A) connection pools without any problemshowever the
X/A one will just not work at all. I spotted on a goggle newsgroup thatsomeone else
had this exact same problem but running on WINNT but there was noresolution. The
following is the trace from the XA trace file:-
ORACLE XA: Version 8.1.7.0.0. RM name = 'Oracle_XA'.
181020.21758.1.-662733300:
xaoopen:xa_info=Oracle_XA+Acc=P/imsi/imsi+SesTm=100+DB=test+Threads=true+LogDir
=.+DbgFl=0x15,rmid=-662733300,flags=0x0
181020.21758.1.-662733300:
ORA-12547: TNS:lost contact
181020.21758.1.-662733300:
xaolgn_help: XAER_RMERR; OCIServerAttach failed. ORA-12547.
181020.21758.1.-662733300:
xaoopen: return -3
I have the whole application up and running fine on a WIN2000 platformwith its own
database on the local machine. Also I can point my WIN2000 application touse the
database on the HPUX11 machine no problem.
This leads me to think this is a TNS related problem as I cant think ofanything
else !.
Any help greatly appreciated...!

Oracle keeping JDBC connections ...

All
has anyone come got any ideas on this:
WLS6.0 sp2 on Win2k
Oracle v8
JDBC connection pool configured with 10 min connections / 50 max conns (in
increments of 5). Shrinking is active, and is set to run every 15mins.
What were seeing is that Oracle doesnt let go of any of the JDBC
connections. It literally keeps them for days on end, until we have to
manually kill them because theyre causing other DB problems.
any ideas ?
tks
will

Hello, I am using ALUI G6 (former Plumtree) and I am experiencing the same problem.
JDBC connections are not released and we reach the connection max number easily.
Please, can somebody help us ?
Thanks for your help,
Kind regards

How to update Connection pool in Unix environment?

I am trying to come up with a secure way to update the username and password in connection pool. The environment is Unix and we won't have access to Admin tool or database to create Repository Variable. Is there a command in unix to update the rpd connection pool? Any suggestions?

Hi,
I believe there is no command available (see the following link for details).
Changing the Oracle BI Database Connection Pool Settings
http://download.oracle.com/docs/cd/E12096_01/books/AnyInConfig/AnyInConfigDataSource5.html
You may also log a SR and confirm this with Oracle Support.
