BC4J DO NOT RE-USE THE ''INACTIVE'' CONNECTIONS, DATABASE IS SATURATED

Question

We developed a J2EE Web application based on the BC4J Framework.
We're using JDevelopper 9.0.3.2 (9.0.2.822 before). The web application is rolled out on Oracle
9ias 9.0.2 patchset 3.
The database used is oracle 9i 9.2.0.
We used the following code to connect to the BC4J:
public void openConnection() {
m_appModule = null;
while (m_appModule == null)
try
m_appModule =
Configuration.createRootApplicationModule(
m_sAppModuleName,m_sAppModuleConfigName);
} catch (JboException e) {
if
(e.getErrorCode().equalsIgnoreCase(AMPoolMessageBundle.EXC_AMPOOL_COOK
IE_ALREADY_EXISTS)){
try {
Thread.currentThread().sleep(5);
} catch (InterruptedException m) {
}else
throw e;
The following code closes the connection to the BC4J
public void closeConnection() {
Configuration.releaseRootApplicationModule(m_appModule,true);
m_appModule = null;
The pooling parameters are the same as the default ones in Jdevelopper.
We noted that certain connections created by the BC4J in the database were
turned "inactive" and were never re-used.
After a certain time, "inactive" connections multiply and the database is
completely saturated.
The BC4J do not re-use the "inactive" connections but try to create new ones.
The "inactive" connections that are never re-used are never killed.
Our only solution is to reboot the database server or the application OC4J
instance to suppress the "inactive" connections.
We tried to configure the BC4J pool in Jdeveloper, but it doesn't work in 9IAS.
Could you please clarify what the problem is? Looking forward to receiving your
feedback on this pressing issue, regards.
