Hello.
I have tried next modification to "java/testing/org/apache/derbyTesting/functionTests/tests/derbynet/dataSourcePermissions_net.java"
.
==================================================
public void shutdown() {
try {
+ waitSessionOfDBClosed("wombat");
+
DriverManager.getConnection(TestUtil.getJdbcUrlPrefix("localhost",
NETWORKSERVER_PORT) +
"wombat;shutdown=true",

}
}
+
+ private static void waitSessionOfDBClosed(String databaseName) {
+
+ try{
+ while(pollSessionOfDB(databaseName)){
+
+ Thread.sleep(1000);
+
+ }
+
+ }catch(Exception e){
+ e.printStackTrace();
+ }
+
+ }
+ private static boolean pollSessionOfDB(String databaseName) throws Exception {
+
+ String runtimeInfo =
+ networkServer.getRuntimeInfo();
+
+ return runtimeInfo.indexOf("\n" +
+ getLabel()+ databaseName) > 0;
+
+ }
+ /**
+ get label same as runtimeInfo.
+ */
+ private static String getLabel(){
+
+ LocalizedResource resource =
+ NetworkServerControlImpl.createLocalizedResource();
+
+ return resource.getTextMessage("DRDA_RuntimeInfoDatabase.I");
+
+ }
=================================
The pollSessionOfDB method executes getRuntimeInfo to NetworkServer and
if there found connection to the database , it returns true.
I found that waitSessionOfDBClosed method never ends in particular called point
in the test program.
Thinking why it happens , I realized that there exists problem of
ConnectionPooling .
Physical connection in connection pool is not closed even if the connection was
closed.
Talking with people,
I came to think processing in dataSourcePermissions_net.java is special as
processing of program which use ConnectionPooling,
because such programs generally do not close database by themself.
Best regards.

Kathey Marsden commented on DERBY-273:
--------------------------------------
I have not been able to follow this thread closely, but I don't think I
understand how Connection Pooling relates to this problem.
Can you post a bit of java code or a standalone java program that demonstrates
the issue?
The derbynet/dataSourcePermissions_net.java test fails intermittently
