VARRAY mapping issues using WLS spk2 connection pools

We have an ongoing issue with VARRAY's and WLS Connection pools. The connection
pool of WebLogic does not support certain data structures of Oracle such as VARRAY.
To create array/struct object in java application, we have to register these
objects through array/struct descriptor methods. These methods require Oracle.sql.Connection
as a parameter. There is no way to get Oracle.sql.Connection from Weblogic Server
Connection Pool because the Oracle.sql.Connection is not serializable.
So, what is the recommended solution for a situation in which the application
tends to need to use VARRAYs and can we instead pass tables?
Any recommendations?

More information on this issue.
I'm using the method DriverManager.getConnection(URL) to get a connection to
the database, passing in the name of the connection pool. This method is
throwing the following SecurityException:
java.lang.SecurityException: User "john" does not have Permission
"reserve"
based on ACL "weblogic.jdbc.connectionPool.ICOM_DEV2_A".
When running under the LDAP realm:
-calls to getConnection() from within a jsp fail
-calls to getConnection() from within a Session Bean or Entity Bean work
-calls to getConnection() from a non-EJB class fail if it is called directly
from the jsp
-calls to getConnection() from a non-EJB class work if it is called from a
Session Bean
When running under the RDBMS realm, all calls to getConnection() work,
whether they are a jsp, non-EJB class or a Session Bean.
Is there some security context that is only present inside the EJB
container?

Difference between using app server connection pooling and using the driver

Hi all,
How to get connection pooling with out application server and tomcat also?
What is the difference between using app server connection pooling and using the driver supported connection pooling?
Regards,

maybe the performance of App server pool is better than the JDBC pool,
for you don't know wether the implementation of the JDBC interface is good or bad.

How to use a JCO connection pool in an EJB?

Hi *,
I want to build a WebService using SAP Web AS (J2EE Engine) that connects to a R/3 ERP (release 4.7).
I thought of building a stateless session bean that will be deployed as webservice. The session bean shall connect to the R/3 in order to call some BAPIs. I'd like to use a JCO connection pool. But I'm not sure, where I should create and destroy the connection pool. Are the EJB methods ejbCreate() and ejbRemove() the right ones? If so, my businness methods would just have to get a connection from the pool and call the BAPIs, right? If not, what do you suggest?
Another question: I already deployed a bean as webservice. Since not really knowing how to use the connection pool, I created a bean with one business method that creates a connection pool whenever it gets called. But if I have to change something in the bean so that I have to redeploy the bean I can't call my business method anymore, because JCO cannot load a native library once again, as it is already loaded, This leads to an exception. So I have to restart the complete engine everytime I redeploy my bean. Are there any workarounds for this problem? I'm not sure whether this is connected to the wrong use of the JCO connection pool.
Kind regards,
Lars

Using Database Resident Connection Pooling

Hi all,
 
In trying to use Database Resident Connection Pooling in Oracle 11g, here is what I have done:
 
SQL> conn / as sysdba
Connected.
SQL> exec DBMS_CONNECTION_POOL.START_POOL();
PL/SQL procedure successfully completed.
SQL> SELECT STATUS,MINSIZE,MAXSIZE,INCRSIZE,SESSION_CACHED_CURSORS,INACTIVITY_TI

In tnsnames.ora file, here is what I have put: 
ORA11G =
(DESCRIPTION =
 (ADDRESS = (PROTOCOL = TCP)(HOST = winxp)(PORT = 1521))
 (CONNECT_DATA =
 (SERVER = DEDICATED)
 (SERVICE_NAME = ora11g)
ORA11GP =
(DESCRIPTION =
 (ADDRESS = (PROTOCOL = TCP)(HOST = winxp)(PORT = 1521))
 (CONNECT_DATA =

) 
 
Now, in sqlplus in attempt to use DRCP, here is what I got:

Is there anything I missed to properly use DRCP.
 
Thanks in advance.

According to Metalink note:

this is a bug on Windows and you should configure client sqlnet.ora so that SQLNET.AUTHENTICATION_SERVICES=NONE.

When is it appropriate to use DataSource (or Connection pooling)?

Hello all,
I'm having some design issues with my application and I'm starting to think that maybe using Connection pooling is not suited for my application. I'm using Tomcat 5.5.12 if it's any relevant..
The architecture of our application looks like this:
Servlets -> App Helper classes -> DB/Accessor classes
looks like the three-tier architecture described in this document: http://www.subrahmanyam.com/articles/servlets/ServletIssues.html
I have read on the Tomcat docs that said that using DataSource is good practice and improves efficiency since it recycles database connections. However, if the accessor/DB classes are not servlets, how can I use the DataSource facility that interacts with Tomcat?
I would like to know whether it is a good idea to use DataSource in my case and if so, how? (since they are not servlets)
Thanks in advance :)

Hi. Thank you for replying.
In the examples that I've seen that use JNDI for Database access, it seems that DataSource is always used--in other words, JNDI and DataSource always seem to be used together (in Servlets). I have not found a case where JNDI is used by itself to access the Database--perhaps I'm not looking in the right place. Could you point me to some documentation maybe?
Thanks a lot!

Some doubts in using resource-ref,connection pool n Data-source

Hi all ,
I need little bit clarification in the following points.
1) Does the connection pool which is created can be displayed in JNDI Tree???
I am seeing only DataSOurce in the JNDI Tree Only.
2)In case of Bean Managed Persistance, in ejb-jar.xml,
I had given the following info.
<resource-ref>
 <res-ref-name>ramukkDataSource</res-ref-name>
 <res-type>javax.sql.DataSource</res-type>
 <res-auth>Container</res-auth>
 </resource-ref>Does the <res-ref-name> refers to Datasource Name??
In weblogic-ejb-jar.xml
<reference-descriptor>
 <resource-description>
 <res-ref-name>ramukkDataSource</res-ref-name>
 <jndi-name>ramukkpool</jndi-name>
 </resource-description>
 </reference-descriptor>Here <jndi-name> refers to connection pool as per weblogic bible book.
If so when i deployed my ejb into the server iam getting Datasource cant be found.
If i had given like the following,
In ejb-jar.xml
<resource-ref>
 <res-ref-name>jdbc/ramuJndi</res-ref-name>
 <res-type>javax.sql.DataSource</res-type>
 <res-auth>Container</res-auth>
 </resource-ref> In weblogic-ejb-jar.xml
 <reference-descriptor>
 <resource-description>
 <res-ref-name>jdbc/ramuJndi</res-ref-name>
 <jndi-name>jdbc/ramuJndi</jndi-name>
 </resource-description>
 </reference-descriptor>Then only my ejb code is successfully deploying doing some work which is as per xpectation.
Can any body tell why I have to give the same name for <res-ref-name> n <jndi-name>??
I am working on this problem from last one week. Still not found the solution.

If not how to deploy the connection pool into server??)
I did not get any errors in the console.
Now i am creating a datasource

I have read the documentation.
I changed my class to oracle.jdbc.pool.OracleConnectionCacheImpl from
oracle.jdbc.pool.OracleConnectionPoolDataSource
I observed in the EM that the Open JDBC Connections and Total JDBC Connections are the same. When I used oracle.jdbc.pool.OracleConnectionPoolDataSource my Total JDBC Connections was increasing and Open JDBC Connections remains 0.
My question still remains unanswered, could some kindly help.
Q? I have defined a data source in JDeveloper using
oracle.jdbc.pool.OracleConnectionCacheImpl
In my java bean I am using the code pasted below to make a connection to database.
Can some one tell whether I am using the correct method of connection pooling mechanism or do I need to make some changes? This application uses JSP and used by lots of people which hits database very frequently.
Any help is highly appreciable.
Thanks in advance.

What about session memory when using BEA Weblogic connection pooling?

Hi,
consider a web application, allowing database connections via a BEA Weblogic 8.1 application server. The app-server is pooling the oracle connections. The oracle database is running in dedicated server mode.
How are the database requests from the web app served by the connection pool from BEA?
1) Does one oracle session serve more than one request simultanously?
2) Does BEA serialize the requests, which means, that a session from the pool is always serving only one request at a time?
If (1) is true, than what about the session memory of Oracle sessions? I understand, that things like package global variables are beeing stored in this session private memory. If (1) is true, the PL/SQL programmer has the same situation, as with programming an Oracle databas in "shared server" mode, that is, he should not use package global variables etc.
Thankful for any ideas...

Reading "Configuring and Using WebLogic JDBC" from weblogic8.1 documentation, I read:
"... Your application "borrows" a connection from the pool, uses it, then returns it to the pool by closing it...."
What do you mean by returning the connection by closing it? Tbe server will either return the connection to the pool or close it...When application code does typical jdbc code, it obtains
a connection via a WebLogic DataSource, which reserves an
unused pooled connection and passes it (transparently wrapped)
to the application. The application uses it, and then closes
it. WebLogic intercepts the close() call via the wrapper, and
puts the DBMS connection back into the WebLogic pool.
The reason, why I as an Oracle programmer ask this is, because every session (=connection)
in Oracle has its own dedicate, private memory for things like global PL/SQL variables.
Now I want to figure out, if you have to careful in programming your databases, when
one Oracle session (=connection) is serving many weblogic requests.It is serving many requests, but always serially. Do note however, that we
also transparently cache/pool prepared and callable statements with the
connection so repeat uses of the connection will be able to get already-made
statements when they call prepareStatement() and prepareCall(). These
long-lived statements will each require a DBMS-side cursor.

How can i know the no .of connections are used in the connection pool

Hi
I am using tomcat connection pool in my project .but how can i know how many connections are used by my project .how can i know how many connections are used plez help me

You mean INSIDE the webapp, using the Admin Console (tomcat docs should be helpful in that case)... Where are you supposed to search for the info?

Using oracle's connection pools and transactional context

Hi!
I have an implementations of existing interfaces ( let's call this layer as
data access layer) which abstracts the connection and transactional session
from the calling application. This implementaion makes use of Oracles JVM
inside the oracle database (8.1.7) to create and maintain the connection
pools and the transactional session (transactional context). I would like
to create differenent implementation, if the calling application is a
session bean running inside the weblogic application server. is there way I
can still use the connection pools and transactinal context that I got from
the oralce if the calling application is a session bean running inside the
weblogic app.. server?
do I have to change any configuration settings in weblogic?. there might
be two scenarios..
the data access layer (the classes which deal with the connection pools and
transactions) might be running inside the oracle's JVM..
the data access layer might be running inside weblogic application server...
thanks...

Oracle: slow performance with SELECT using ojdbc14 and connection pooling

Hello,
i'm working hard the last days to solve a performance problem with our customer using a oracle 10g database. For testing I used our oracle 9.2.0.1.0 database which shows the same symptoms. All doing solved nothing: the performance while using this oracle is much slower than other databases. This result I cannot trust and so I need some advice. What is missing to improve the performance on the java side?
The webapplication I use runs fast on MySQL 4.x and SQLServer 2000, but on the above mentioned Oracle it was always 4 times slower. The webapplication uses a lot of simple SELECT-Statements without complicated joins and so on (because it should run on many different databases). Doing some days of creating tests within this webapplication, I was not able to find any entrance point for a change. All databases server I'm using, having only the default configurations after a common installation.
To reduce the complexity I wrote a simple java application with connection pooling using only the latest libraries from apache-commons(dbcp, pool), and the latest ojdbc14 for oracle 9.2.
First the results than the code: MySQL needed less than 1000 millisecond, SQLServer around 1000 milliseconds and Oracle over 2000 milliseconds. I stopped pooling and the results are for Oracle even worse: over 18000 milliseconds (mysql:2500, sqlserver:4100).
I changed the classes for Oracle and used the class oracle.jdbc.pool.OracleConnectionCacheImpl from the ojdbc14-library. No difference (around 100 milliseconds more or less).
The only Select-Statement works on this table, which has one index on HICTGID.
It contains 259 entrances.:
CREATE TABLE HIERARCHYCATEGORY (
HICTGID NUMBER (19) NOT NULL,
HICTGLEVEL NUMBER (10) NOT NULL,
HICTGEXTID NUMBER (19) NOT NULL,
HICTGEXTPARENTID NUMBER (19) NOT NULL,
HICTGNAME VARCHAR2(255) NOT NULL
);The application simply loops through this table using
SELECT Hictgid, Hictgname FROM HIERARCHYCATEGORY WHERE HICTGID = ?, but I always open a connection before this query and closes this connection afterwards. So I use the pooling as much as possible. That's all SQL I'm using.
 protected static DataSource setupDataSource(String sDriver, String sUrl, String sUser, String sPwd) throws SQLException {
 BasicDataSource ds = new BasicDataSource();
 ds.setDriverClassName(sDriver);
 ds.setUsername(sUser);
 ds.setPassword(sPwd);
 ds.setUrl(sUrl);
 // The maximum number of active connections:
 ds.setMaxActive(3);
 // The maximum number of active connections that can remain idle in the pool,
 // without extra ones being released, or zero for no limit:
 ds.setMaxIdle(3);
 // The maximum number of milliseconds that the pool will wait (when there are no available connections)
 // for a connection to be returned before throwing an exception, or -1 to wait indefinitely:
 ds.setMaxWait(3000);
 return ds;
 }I can switch by using external properties between three databases (oracle, mysql and sqlserver) and if I want I can switch pooling off. And all actions I'm interested are logged by Log4J.
 public static Connection getConnection() throws SQLException {
 Connection result = null;
 String sJdbcDriver = m_oJbProp.getString("jdbcDriver");
 String sJdbcUrl = m_oJbProp.getString("databaseConnection");
 String sJdbcUser = m_oJbProp.getString("dbUsername");
 String sJdbcPwd = m_oJbProp.getString("dbPassword");
 try {
 if (m_oJbProp.getString("useConnectionPooling").equals("true")) {
 if (log.isDebugEnabled()) {
 log.debug("ConnectionPooling true");
 if(null == m_ds) {
 m_ds = setupDataSource(sJdbcDriver,sJdbcUrl,sJdbcUser,sJdbcPwd);
 if (log.isDebugEnabled()) {
 log.debug("DataSource created");
 result = m_ds.getConnection();
 } else {
 // No connection pooling:
 if (log.isDebugEnabled()) {
 log.debug("ConnectionPooling false");
 try {
 Class.forName(sJdbcDriver);
 result = DriverManager.getConnection(sJdbcUrl, sJdbcUser, sJdbcPwd);
 } catch (ClassNotFoundException cnf) {
 log.error("Exception: Class Not Found. ", cnf);
 System.exit(0);
(.. ErrorHandling ...)Here is the code fragment which is doing the work:
 StringBuffer sb = new StringBuffer();
 while (lNextBottom <= lNextCeiling) {

 innerSelStmt = con.prepareStatement("SELECT Hictgid, Hictgname FROM HIERARCHYCATEGORY WHERE HICTGID = ?");

 rsInner.close();
 con.close();
 lNextBottom++;
 if (log.isInfoEnabled()) {
 log.info("\rResult values: Hictgid, Hictgname \r");
 log.info(sb.toString());
 }and the main method:
 public static void main(String[] args) {
 try {
 long lStartTime = System.currentTimeMillis();
 JdbcBasic oJb = new JdbcBasic();
 boolean bSuccess = false;
 bSuccess = oJb.getHierarchycategories();
 if (log.isInfoEnabled()) {
 log.info("Running time: " + (System.currentTimeMillis() - lStartTime));
 if (null != m_ds) {
 printDataSourceStats(m_ds);
 shutdownDataSource(m_ds);
 if (log.isInfoEnabled()) {
 log.info("Datasource closed.");
 } catch (SQLException sqe) {
 log.error("SQLException within main-method", sqe);
 }My database values are
databaseConnection=jdbc:oracle:thin:@SERVERDB:1521:ora
jdbcDriver=oracle.jdbc.driver.OracleDriver
databaseConnection=jdbc:jtds:sqlserver://SERVERDB:1433/testdb
jdbcDriver=net.sourceforge.jtds.jdbc.Driver
databaseConnection=jdbc:mysql://localhost/testdb
jdbcDriver=com.mysql.jdbc.Driver
dbUsername=testusr
dbPassword=testpwdThanks for your reading and maybe for your help.

A few comments.
There is of course another difference between your test cases then just the database. There is also the driver. And I suspect that in at least the case with the jtds driver it is helping you along where you are doing something silly and the Oracle driver is not.
Before I explain the next part I would say the speed differences between MS-SQL and MySQL look about right I think you are aiming here for MS-SQL level performance not MySQL. (For a bunch of reasons MySQL is inherently faster but there are MANY drawbacks as well which have been well discussed on previous threads)
Here is where I believe your problem lies
while (lNextBottom <= lNextCeiling) {
 con = getConnection();
 innerSelStmt = con.prepareStatement("SELECT Hictgid, Hictgname FROM HIERARCHYCATEGORY WHERE HICTGID = ?");
 innerSelStmt.setLong(1, lNextBottom);
 rsInner = innerSelStmt.executeQuery();
 if ((rsInner != null) && (rsInner.next())) {
 sb.append(rsInner.getLong(1) + ", " + rsInner.getString(2) + "\r");
 if (log.isDebugEnabled()) {
 log.debug("Inner Statement: " + rsInner.getLong(1) + "\r");
 rsInner.close();
 con.close();
 lNextBottom++;
 }There at least four things that are wrong with above.
1) Why are you preparing the statement INSIDE the loop. Let us for a moment say that the loop will spin 100 times. That means that you are preparing the same statement 100 times. This is bad. It is also very relevant because for example the Jtds driver is going to be caching the prepared statements you make so that actually while you try and prepare it 100 times it only actually does it once... but in Oracle I don't know what it is doing for sure but if it is preparing on each pass well than that bit of it is going take 100 times longer then it should.
2) You are opening and closing the connection on each pass through the loop... also a terrible idea. You need to fix this first so that you can repeatedly use the same prepared statement.
3) Why are you looping in the first place? More on this later.
4) Where do you close the PreparedStatement? It doesn't look like you do.
Okay so for starters your loop should look a lot more like this...
code]
con = getConnection();
innerSelStmt = con.prepareStatement("SELECT Hictgid, Hictgname FROM HIERARCHYCATEGORY WHERE HICTGID = ?");
while (lNextBottom <= lNextCeiling) {
innerSelStmt.setLong(1, lNextBottom);
rsInner = innerSelStmt.executeQuery();
if ((rsInner != null) && (rsInner.next())) {
sb.append(rsInner.getLong(1) + ", " + rsInner.getString(2) + "\r");
rsInner.close();
lNextBottom++;
innerSelStmt.close();
con.close();
I think the code above (and you can put your debug stuff back if you want) which uses ONE connection and ONE prepared Statement will improve your performance dramatically.
The other question though I would as is why in the hell you are doing 100 or whatever number of queries anyway. This can be done all in ONE query which again will improve performance.
Your query and such should look like this I think.
String sql = "SELECT Hictgid, Hictgname FROM HIERARCHYCATEGORY WHERE HICTGID >=? AND HICTGID<=?";
PreparedStatement ps = conn.prepareStatement(sql);
ps.setLong(1,lNextBottom );
ps.setLong(2,lNextCeiling);
ResultSet rs = ps.executeQuery();
while(rs.next()){
// your appending to string buffer code goes here
}and I can't understand why you're not doing that in the first place.

Read data using 2 diff connection pool for same DB folder in physical layer

Hi All,
i am using two connection pool which have different dsn connection information (both are directed to different database name or database server)..
so if i view the data of any table, a prompt will come asking for the connection pool, so how do i automize it....?
how do i set the different connection pool for different tables?
please let me know if u need further informtaion to understand my problem..
thnx...

thnx Stijn..
yupe that i know...
actually i have total of around 300 tables in physical layer (in both the schemas..) , around 12 fact and 100 dimension tables in bmm and same in the presentation layer...
so i think u can guess how many joins and other stuff, i have made in my bmm layer..
if now i will start modifying all this it will take lot of time...
i am just wondering that there is no alternative for this...
as when i check my data from the physical layer then a prompt ask for the connection pool (i have already made two connection pool..) so there could be some alternative way to automize the default connection pool setting for the tables/schemas folders in case if more than one connection pool exits under the same database in the physical layer...
isn't it?
thnx again..

Which DataSource class to use for DB connection pooling?

Hi,
can someone point me in the direction of some (sample?working?) data-sources.xml configurations that pool the DB connections please. I don't have a requirement for TPC, so either native or emulated would be fine, but I need a LOT less db connections for multiple users using stateless sessions on the same database/datasource than I am currently getting. An added bonus would be being able to use the "Monitor Performance" button in Enterprise Manager.
thanks
Brigette

Thanks Rodrigo for you reply.
In Data Base user is exist and manually user mapping is working only through code i am getting error. Using code user is creating but mapping is not happening. I am sending ep6User user as iUser please find requested code.
Please suggest Thanks in advanced!!!
public UmeUser processRequest(com.ibm.dsml2.parser.AddRequest addRequest) {
 UmeUser ep6User = null;
 try {
 Enumeration enumAddRequestAttr = addRequest.enumerateAttr();
 Properties userAttributes = new Properties();
 while (enumAddRequestAttr.hasMoreElements()) {
 com.ibm.dsml2.parser.Attr attr = (com.ibm.dsml2.parser.Attr) enumAddRequestAttr.nextElement();
 if (attr.getValueCount() == 1) {
 userAttributes.put(attr.getName(), getAttributeValue(attr));
 else {
 List list = new ArrayList(attr.getValueCount());
 for (int i = 0; i < attr.getValueCount(); i++) {
 list.add(getAttributeValue(attr, i));
 userAttributes.put(attr.getName(), list);
 ep6User = new UmeUser(userAttributes, logger);
 catch (Exception e) {
 logger.log(this.getClass().getName(), e);
 return ep6User;

Problem in retriving varray when using weblogic connection pool

Hi,
I had similar problem when we I am using the weblogic connection pool. I had similar setup i.e weblogic 5.1 servicepack9 and oracle 8.1.7.
I cofigarud the weblogic connection pool using Oracle thin driver.
But if I am using with oracle thin driver directly I am able to retrive.
If any one know how to retrive varray from procedure using weblogic connection pool please send me it.
Thanx.
