Is the initial jdbc connection handshake secure?

My application needs to ensure that all passwords going through the network is encrypted, including that of the database user password when the application connects to the database.
My question is the initial call to get a database connection secure? i.e. is the database password encrypted first before sent over the network?
Can anyone confirm?

There's probably something in the Security documents somewhere, but I don't know where.
JDBC does the logon handshake exactly the same as OCI; the bits on the network are identical. Maybe there is something in the OCI documentation that answers your question. I suppose there could be something in the Security chapter of the Oracle JDBC Developer's Guide, but I don't recall anything.

I want the complete JDBC Connection details

Hi
I want to have a complete JDBC Connection like how to insert records, update/edit records and deleting records. Do u know a website or can anybody give an entire code having all the functions of JDBC.

I'm a Nigerian diplomat. If you send me a check for $1000 USD I'll send you $1M and all those code samples.
It'd be better for you to go read and try them yourself. They're not that hard.
It'd also be better for you not to be so demanding. This is a volunteer forum, and nobody owes you anything. Your manners are appalling.

Secure JDBC Connection

Our application uses JDBC to connect to Sybase, Oracle and MSSQL databases. I do not see any way to encrypt the password. But the machine has IPSec installed. My questions are:
Is the JDBC connection considered secure with IPSec installed
If so, doe IPSec has to exist on both source and destination machines.

Whether that is good enough depends on your security policy and business needs.
If so, doe IPSec has to exist on both source and destination machines.Of course.
IPSec of course will require that you mandate the use of it. You will have no control of it in your code. You won't even be able to detect it.
Obviously finding secure drivers would allow you to insure it at the code level.

Errors using weblogic sql driver: "No JDBC connection can be made because the transaction state is marked rollback"

One of our customers starts to encounter this error message recently.
We checked our log files. It seems that the error happens when
to obtain a jdbc connection. Have anyone seen similar problems
and knows how to fix it? thanks in advance.
We are using weblogic server 6.1sp2, and weblogic sql type 4 driver.
The functions that invoke the jdbc calls are stateless session bean
methods with their transaction attributes marked as Required.
There is no nested calls of these methods.
A partial stack trace we obtained is as following:

Joe,
We got the exact same error message. The error came after we got theJDBC connection,
and trying to create statement off it.
It occurs intermitently when we are running another standalone JAVAapp to do
some end of day work, which results in the DB Server being very busy(90+%CPU
usage) for about 5 minutes. We see a surge of requests to the WLSJDBC Connection
pool. This would sometimes result in all our subsequent DB requeststo fail and
lead to a crash.
We are using WLS6.0SP1. I do not think there's a 30 seconds wait leadingto a
connection timeout that caused this(rather it is the end effect).
Can you give us a more detailed explanation? Is there a miscommunicationbetween
our DB(Sybase12) and WLS?Hi. It looks to you like it's after you get the connection, but really
it's when the server is
gettng the pool connection. For performance/synchronization reasons we
do a clever
delay: When your code asks for a pool connection we quickly give you
the pool wrapper,
but we delay actually reserving the real underlying DBMS connection until
your first
real need for a connection, at your first JDBC call, such as createStatement()
etc.
It is while waiting for a pool connection long enough for the transaction
coordinator
to have timed you out before you ever get a chance. It's nothing to do
with the
DBMS or even JDBC, I believe. I think the weblogic server either has
too few execute-threads
and/or too few CPU cycles to do the work load.
Okay, so there's a lazy initialization of the connection.
From reading our log I believe our failur is immediate rather
than waiting for 30+ seconds(the default setting) from the DB,
the timeout occurred later as a result. At the time either because the DB Server
is very busy.
Since we are running WLS6.0 we have only one connection pool,
we have defined a max of 150 threads in the pool. While this
is happening the DB Server is being pinned by an overnight job,
but the WLS Server is not busy at all. The DB and WLS resides
on different physical boxes.
We also have a thread dump from the WLS console when we rebooted the server, it
showed that we are hanging on to the thread & jdbc
connections after these exceptions has occurred instead of releasing them, note
"16083"(~4.5 hours) seconds has passed:
142 116222 Retry rollback request for tx: 'transaction=(IdHash=2963855,Name =
[EJB UserManagerBeanImpl.signalICUserServletHeartBeat()],Xid=30643:8f3838f3709bf53d,Status=Rolling
Back. [Reason = Unknown],numRepliesOwedMe=0,numRepliesOwedOthers=0,seconds since

weblogic.transaction.name=[EJB UserManagerBeanImpl.signalICUserServletHeartBeat()]}))'
Scheduled Trigger
So I would argue this problem actually chewed up resources on the WLS server.

Weblogic 6.1 sp1 jdbc connection to SQL Srv 7; receiving resources not available

We've been running some load balancing testing on our website and at the high end
of the number of concurrent users, we begin to receive "QLException: java.sql.SQLException:

the 40 concurrent user mark. I've set the max JDBC connections to around 50,
initial connections to 20, capacity increment to 2 and the shrink period to 1

to always close a pool connection regardless of any exception, by the end of every user
request, then you should need only as many connections in the pool as there are execute
threads in the server. Do you have more than 50 execute threads?

Open/total jdbc connections

With Oracle9iR2 AS installed, I notice that there are always open JDBC connections. I explicitly close them from all my JSP files (and the statement and the resultset objects as well). Actually, the total JDBC connections are always 2 times the open JDBC connections.
The DataSource class I use is com.evermind.sql.DriverManagerDataSource. Is this a problem? Will this be corrected in any future release?
Thanx

Interesting thread. Have also had problems with the connection pool (903 standalone).
One problem in particular is that if min-connections is used, then those pool-connections are really never closed "physically". This means that a lot of open cursors are never released in the db (even though the "connections" used by the code from the pool are closed). Not so good under heavy load.
Posting a snippet from a connection pool entry we have. Maybe it will help some of you guys.
<data-source
class="com.evermind.sql.DriverManagerDataSource"
name="SomeDS"
location="jdbc/SomeDBCoreDS"
xa-location="jdbc/xa/SomeDBXADS"
ejb-location="SomeDB"
connection-driver="oracle.jdbc.driver.OracleDriver"
username="user"
password="pwd"
url="jdbc:oracle:thin:@127.0.0.1:1521:SOMESID"
inactivity-timeout="300" <-- Will close connections after 300 sec of inactivity
min-connections="0"
max-connections="20" <-- Larger on prod machine of course
stmt-cache-size="100"
/>
I have experimented wildly with these settings and this is the most stable. Sure, it's nice to always have connections ready in the pool. But as I said. Open cursors WILL accumulate in your db if you use the min-connections set to a positive number (check your v$). This is our experience anyway. These settings have stopped us from getting db errors such as maximum open cursors exceeded and too many connections open using 903.

Jonas

BI JDBC connection failure with MS SQL 2005 - but Portal JDBC is working

I am a portal novice.
I wanted to get tables in the visual composer. so i created the protal jdbc connection to MS SQL 2005. which is working fine.
Later i found i need BI jdbc for retreving tables from sql server. when i followed all the steps in the how to document, my connection test is failing. below is the log.
Test Details:
The test consists of the following steps:
1. Retrieve the default alias of the system
2. Check the connection to the backend application using the connector defined in this system object

JDBC connection w/Japanese server

I have an English client doing the following JDBC connection to a Japanese server:
m_connection = DriverManager.getConnection(
m_connectionStr,
m_user, m_password );
This always results in a SQL exception with the following three messages:

What do I need to do to get a connection and to send queries that are stored in English?
Thanks,
pds2

The connection string is:
jdbc:microsoft:sqlserver://10.4.10.34:1433;databaseName=MSSQL;
I tried the following with the same bad results as before:
java.util.Properties prop = new java.util.Properties();
prop.setProperty( "user", m_user );
prop.setProperty( "password", m_password );
prop.setProperty( "characterEncoding", "utf8" );
prop.setProperty( "useUnicode", "true" );
m_connection = DriverManager.getConnection(
m_connectionStr, prop );
Will some variation of this work?

BC4J: Getting a JDBC Connection out of an Application Module.

Hi all! Good Morning!
I have an application that uses JasperReports to print some reports. The filling mechanism of JasperReports requires a JDBC Connection object to work. At present, i am using the ConnectionMetadata Object from the AM to get the JDBC URL and user name to create a new Connection with DriverManager.getConnection(), but there is no way to get the DB password. Is there any way to get the underlying JDBC Connection inside a method in the ApplicationModule? something like this.getJDBCConnection()? If so, does this method draws the connection from the AM Connection Pool, or is it a "stranded" connection?
Thanks a lot! Your help is greatly appreciated!

Are they in external client programs or are they in serverside code? Are you running
UserTransactions, such as in transactional EJBs etc?

How to connect the database (JDBC) using service name rather than SID

How should we make the connection to the database using service name. Initially, we are using the SID to make the database connection, with following setting in the data-source.xml in OC4J using ABCDB as the SID.
<data-sources>
     <data-source
          class="com.evermind.sql.DriverManagerDataSource"
          name="jdbc/ABCDB"
          location="jdbc/ABCDB"
          pooled-location="jdbc/OracleDSPooled"
          xa-location="jdbc/xa/OracleDSXA"
          connection-driver="oracle.jdbc.driver.OracleDriver"
          username="ABC"
          password="ABC"
          url="jdbc:oracle:thin:@191.1.4.126:1521:ABCDB"
     />
</data-sources>
It work, but now we need to make the connection using this service name ABCSERVICE, but it doesn't work in the OC4J (JDBC). May I know how should we handle this connection?
Thanks and Regards,
Pang

Finally, I got the solution to make the database connection using service name, with putting the tnsname setting in URL portion.
url="jdbc:oracle:thin:@(description=(address=(host=191.1.4.126)(protocol=tcp)(port=1521))(connect_data=(SERVICE_NAME = ABCSERVICE)))"
And now, it is working fine.

Pang

My question is, can we spawn any other kind of connection from an EJB to another database on some remote machine, this would involve using the thin or oci drivers, i try but get security exceptions and access privilege exception though the account i use is privilegded for database operations. Can someone answer my question please.

see reply in one of the four other forums you posted the same question to !!

more than 200 Waiting For Connection Total.<<This is from a JDBC pool? If so, then you have more users than your pool can handle.
How many initial / maximum connections does this particular pool allow, and how many servers are within your cluster?
What is your applicaiton's session timeout value?
Ask your DBA how many connections the database currently allows.
You can also configure the shrink period of the pool if your user sessions are short, or if your users are not logging out ( which results in their session holding a connection until the session times out ).
Are you seeing Leaked Connections ( you can configure the console to report these )?

Is the initial jdbc connection handshake secure?
