JDBC20 connect pool issue using OCI driver
I tried to use:
url=jdbc20:weblogic:oracle.
driver=weblogic.jdbc20.oci.Driver
and got the following error:
<Jul 11, 2001 5:52:34 PM PDT> <Error> <JDBC Connection Pool> <Cannot
startup connection pool "ExrGlobalDbPool" Cannot load driver class:
weblogic.jdbc20.oci.Driver>

If you use the driver provided by Oracle, then use the following:
url=jdbc:oracle:oci8:
driver=oracle.jdbc.driver.OracleDriver

Hi,
What is the correct way to define the url in the jdbc connection pool
to
support jdbc20
features using Oracle OCI driver?
Thanks!

Can I create connection pool by oracle oci driver?
Can I create connection pool by oracle oci driver?My weblogic's version is 6.1 sp2 and oracle is 9.0.1.2.
I have some trouble with connection pool created by weblogic jDriver.
I try to read Timestamp from table and I always get the exception.It told me that ORA-00932: inconsistent datatypes.
So I created another pool by oracle thin driver and everything was right.Then I created other pool by oracle oci driver,but something were wrong. 'Could not create pool connection. The DBMS driver exception was:java.sql.SQLException: ORA-06401: NETCMN:Invalid driver designator'
The oci pool's parameters are below lines.
url: jdbc:oracle:oci:@COCO
Driver Classname: oracle.jdbc.driver.OracleDriver
Properties: user=scott;password=tiger;protocol=oci
If I get connection directly,don't use connection pool,I can get right connection.But why didn't I create pool by oci driver?Maybe weblogic7 or weblogic8 will work good?Venkat Amirineni wrote:
Hi Joe,
I am also trying to create a connection pool using Oracle Oci XA. Weblogic
type 2 oci threads hanging on native calls and suggested to go for thin drivers.
But we want to try with Oracle Oci drivers.. Can you please tell us how to
create a conn pool using Oracle Oci.. Just the driverclass and url is enough
or need any classpath settings etc..
Thanks in advance for your quick reply.Hi. As far as driver properties, just use what Oracle says to. Any pool properties
that we recommend for XA would still apply. Note that Oracle themselves recommends
the thin driver over their OCI one:

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,
Muralimaybe 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. -
Problem JDBC Connection using OCI Driver on Weblogic Portal on Linux
Hi Team,
I want a JDBC connection using OCI Driver in Weblogic Portal 8.1 sp4 on Linux. When I had tested using JDBC connection using Plain Java Code it is working. Also when I create the OCI Connection Weblogic Connection Pool it is working.
But My Requirement is to create the connection using Java Code in Portal Application
But When I create OCI connection in the code it is throwing NO SUITABLE DRIVER Found.
---------- Code in Plain Java Code ------------ Same code is used in Weblogic Portal Application --------------------------------
public static void main(String[] args) throws Exception{
Class.forName("oracle.jdbc.driver.OracleDriver");
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
String url="jdbc:oracle:oci8:@TESTDB";
Properties props = new Properties();
props.put("user","scott");
props.put("password","tiger");
conn=DriverManager.getConnection(url,props);
When I am using the same code in Weblogic Portal and Deployed on Weblogic Portal Server 8.1 SP4 it is throwing following error.
-------------- Exception on Server Log --------------------
java.sql.SQLException: No suitable driver

My Environment is
LINUX

Edited by: vishnuk on Oct 23, 2009 4:10 AMHi Vishnu
Looks like a classloader issue. BEA class loader is very tricky. Any jar added manually in classpath, will end up loading only those classes. Any imports that we have in any of those classes do not get loaded. Anyhow, coming to your point, add classes12.jar inside your portal web project Web-Inf/lib folder and see if that helps. Usually thats where we put all the JARs for 8.1 SPxx applications. If this still breaks, then remove the jar from web-inf/lib folder and add under your portal app App-Inf/lib folder. First try with app-inf/lib folder having this jar. If not then with web-inf/lib. Basically web-inf is specific to that web app only. If you have a different app having this jdbc code, then put under app-inf/lib folder. Make sure that you remove the classes12.jar that you added in classpath either in env variable or in setdomainenv.cmd file.
When weblogic uses native OCI Drivers, it refers to jars at this location: ....\beawlp814\weblogic81\server\ext\jdbc\oracle\10g or 9g. Try using one of these jars and see if that works. Most of the times I used these jars only for oracle specific native drivers.
Word of caution. Try to use Connection Pool and a DataSource created in weblogic console for your jdbc code. This Datasource can still use the Oracle drivers that you want (instead of BEA Weblogic wrapper oci drivers) located in above location. Use JNDI Lookup and get Datasource and then connection. This is more recommended approach with many advantages then using DriverManager approach..

Please help me resolve the problem
Thanks,
KumarYou should confirm that you can connect to the DB with a simple Java class using the url that the code you posted is using.
This will show that the OCI client is installed and executing properly. If you can't connect externally you will need to fix that first.
Is the Oracle client installed on the same machine the JDBC code is running on? -

my global database name and SID value in mohan
Thanking uBathina,
Your problem is in your URL:
String url="jdbc:oracle://oci8:/@mohan";As far as I know, you can't use the forward-slash character ("/"), by itself, as your database login name -- you must supply a "login/password". I don't know why, and if you don't like it, I suggest you create a TAR (Technical Assistance Request) via the MetaLink Web site.
I recall similar questions being asked in this forum -- have you tried searching the forum archives?
Good Luck,
Avi. -
I am now tring to access database use oci8 driver in solaris2.5/oracle816/jdk 1.1.6/classes111.zip, I got a error message "Invalid driver designator" but I am now running the code in a local machine so may be it is not sql*net issue.
who knows the reason, thanks in advance.Please check the way you are trying to make the connection to the database from Java.
I have just received the same error message (ORA-06401, isn`t it?) and checking my DriverManager.getConnection I have realised that I am using the syntax for the use of the THIN Driver not the OCI. I have not still test it, but I am sure that is the problem.
You can consult the Oracle8i JDBC Developer's Guide and Reference (http://technet.oracle.com/doc/java.815/a64685/basic1.htm) to see how to create an OCI and Thin connection.
Anyway, I transcribe you what it says :
Opening a Connection for the JDBC OCI Driver
For the JDBC OCI driver, you can specify the database by a TNSNAMES entry. You can find the available TNSNAMES entries listed in the file tnsnames.ora on the client computer from which you are connecting. On Windows NT this file is located in [ORACLE_HOME]\NETWORK\ADMIN. On UNIX systems, you can find it in /var/opt/oracle.
For example, if you want to connect to the database on host myhost as user scott with password tiger that has a TNSNAMES entry of MyHostString, enter:
Connection conn =
DriverManager.getConnection ("jdbc:oracle:oci8:@MyHostString",
"scott", "tiger");
Note that both the ":" and "@" characters are necessary.
For the JDBC OCI driver (as with the Thin driver), you can also specify the database with a Net8 keyword-value pair. This is less readable than a TNSNAMES entry but does not depend on the accuracy of the TNSNAMES.ORA file. The Net8 keyword-value pair also works with other JDBC drivers.
For example, if you want to connect to the database on host myhost that has a TCP/IP listener up on port 1521, and the SID (system identifier) is orcl, use a statement such as:
Connection conn =
DriverManager.getConnection("jdbc:oracle:oci8:@(description=(address=(host= myhost)(protocol=tcp)(port=1521))(connect_data=(sid=orcl)))",
"scott", "tiger");

Connection pool issues with Mysql
Hi,
I have defined sufficient read connections (50) in the toplink configuration, I am finding toplink is not releasing the connections in Mysql, this is when run from Jboss App server.
Is anyone aware of toplink connection pool issues with MySql?
thanksTopLink always closes connections, I cannot see how this could occur.
Please include your persistence.xml or sessions.xml. Also ensure you are closing your EntityManager or ClientSession, especially if using exclusive connections.
Also include the exception you are getting.

Can I use OCI driver to test database connection in JDeveloper9.0.3
When using JDeveloper 3.2.3, I can use oci8 driver to test the databse connection.
Then I want oci8 driver work in JDeveloper9.0.2 or JDeveloper 9.0.3. However, it cannot work.
(Note: but thin driver works fine)
First, I read the help file and setup ORACLE_HOME environment variable and install
OCI client driver ocijdbc9.dll on my compuetr. Then some exception is happening when I test again.
So I want to know, does anyone succeed in testing the connection via oci driver
and how to fix this problem.
Thanks a lot.Hi !
You MUST use jdbc library supplied with Oracle client ( so classes12.zip from $ORACLE_HOME/jdbc/lib ), not with JDeveloper - this one might be incopatible with oci native libraries.
I hope , this helps.

Connection Pool Failure: "No suitable driver"
Hi,
Upon server startup, I get the following result:
<Nov 7, 2001 4:18:32 PM CST> <Error> <JDBC> <Cannot startup connection pool "ora
cleTrufflePool" No suitable driver>
I assumed it was a path problem, but in the startWebLogic.cmd script I've set the PATH and CLASSPATH variables to the same as in a separate command window that can successfully dbping the Oracle db.
One thing I completely don't understand is what the URL value should be for the pool, and I can't see a pattern in the examples and docs I've found on this. Here are my pool settings, at any rate:
Name: oracleTrufflePool
URL: myOracleServerName
Driver Classname: weblogic.jdbc.oci.Driver
Properties:
user=user
password=password
server=myOracleServerName
ACLName: user
Password: password
As you can see, I also don't understand whether the Oracle user name and password must be duplicated in the Properties section, or should they really only be listed in the ACLName and Password fields (in the Server Console UI)?
TIA,
SteveHi. The issue is that the URL you give is not the URL the driver (weblogic.jdbc.oci.Driver)
wants. The URL should be "jdbc:webLogic:oci". The properties user, password and server
will be passed to the driver for conenction attempts. The ACL is for who gets to use the
pool, and the other password entry is only if you need the DBMS password to be encrypted
in the XML. If so, set that password value, and don't have it in the driver properties.

Unable to connect to Oracle using OCI Drivers on Linux
Hi Everyone!
I am facing a peculiar issue while using Instant Client on Linux ( 64Bit ) running on Red Hat 4.1.
I have downloaded the instant client version 10.2.0.3(.zip) .so files from the below URL
http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/linuxx86_64soft.html
UPloaded all the files to a directory under /opt and changed the .bash_profile file, the latest content looks like
ORACLE_HOME=/opt/instantclient_10_2
export ORACLE_HOME
PATH=$PATH:$ORACLE_HOME
export PATH
TNS_ADMIN=/opt/instantclient_10_2
export TNS_ADMIN

export PATH
CLASSPATH=/opt/instantclient_10_2:/opt/instantclient_10_2/ojdbc.jar
export CLASSPATH
Java.library.path=/opt/instantclient_10_2
export Java.library.path
As i have downloaded the Sqlplus utility as well, i am able to connect to the Oracle FARM via sqlplus.
On the other hand, i am unable to connect to the same database via the application. It constantly gives me the following exception,

I have used the classes12.jar and ojdbc.jar which came with the download and nothing seems to work. A bit surprising when sqlplus works and not the application. I suspect there could be an issue with the driver class. I have been struggling to figure this out for days now...
Can anyone please share their thoughts if something similar was observed earlier please.
Any quick help will highly be appreciated.ORACLE_HOME=/opt/instantclient_10_2
export ORACLE_HOMEYou don't set ORACLE_HOME with Instant Client.
PATH=$PATH:$LD_LIBRARY_PATH
export PATHThis is unnecessary.
CLASSPATH=/opt/instantclient_10_2:/opt/instantclient_10_2/ojdbc.jar
export CLASSPATHThis is wrong.
It should be:
CLASSPATH=/opt/instantclient_10_2/ojdbc14.jar:<whatever else you need there>
Java.library.path=/opt/instantclient_10_2
export Java.library.pathThis is useless; java.library.path is not an environment variable.
java.lang.UnsatisfiedLinkError: no ocijdbc10 in java.library.pathThe case is pretty clear. You want to use the OCI driver (your URL starts with "jdbc:oracle:oci:"), so the Java Virtual Machine is looking for libocijdbc10.so in the Java library path but cannot find it.
What is also clear is that the program does not use the CLASSPATH environment variable you set, because then it would never have found the Oracle Driver.
So it seems that your program is ignoring the environment you set (which would explain why it also ignores LD_LIBRARY_PATH which you set correctly).
You must have the environment variables set and exported in the shell that starts the "java" executable.
Also, check that there is no other ojdbc14.jar on this machine (use "find").
To help you debug your problem, let me explain how Sun Java sets Java library path on Linux:
- If you start java with "java -Djava.library.path=/some/dir:/other/dir ...", the Java library path is set to exactly that value.
- If you do not specify -Djava.library.path, the Java library path is taken from the environment variable LD_LIBRARY_PATH.
- Directories listed in /etc/ld.so.conf have no influence on the Java library path (which gave me quite a headache in the beginning).
Do you really need the OCI Driver? If you can do with the Thin Driver (i.e., use an URL that starts with "jdbc:oracle:thin:") you don't need any shared libraries at all.
Yours,

Poor performance caused by using OCI driver?
[Sorry for the multipost]
I'm working on a medium-sized Apache / Tomcat / WLS 5.10 / Oracle
system hosted on some 4-processor Suns. The Apache / Tomcat tier
uses one box, the WebLogic tier uses another, and the Oracle tier
uses a third.
We've found that the performance, measured as the time it takes user
operations like loading a page that displays database data, gets
unacceptably bad at suspiciously low loads. When the system is in
this state, none of the machines appears to be pushed very hard.
There's no significant paging going on, the disk and network I/O
isn't out of line, and the CPU load just isn't high enough to
explain what's going on. Only the WebLogic tier shows a load over
10%. When the system is perceived as too slow by the users, the
CPU load on this tier is only 30-40%.
To try to find out what's going on, I did a series of thread dumps.
When the system is heavily loaded, I only see about three Oracle
statements currently being processed (runnable threads with call
stacks inside weblogic.db.oci.*). What I do see lots of is blocked
(and one runnable) threads inside
weblogic.rjvm.RJVMImpl.removePeerGoneListener or
weblogic.rjvm.RJVMImpl.addPeerGoneListener. These threads appear to
be attempting to obtain or release database connections.
I don't know why, but the site is configured to use the WebLogic OCI
driver for Oracle, instead of the Oracle-supplied thin driver. Is what I'm
seeing what Sun is describing in this paragraph
(excerpted from http://java.sun.com/docs/hotspot/PerformanceFAQ.html#24):
Oracle provides two types of database drivers: a type-2
driver, called the OCI (Oracle Call Interface) driver
that utilizes native code, and a type-4 pure Java driver
called the thin driver. In single processor environments,
the thin driver works somewhat better than the OCI driver
because of the JNI overhead associated with the OCI
driver. On multi-processor configuations, synchronization
points within Solaris used by the OCI driver become big
bottlenecks and prevent scaling. We recommend using the
thin driver in all cases.
-- ErikHi. I'll chip in here too. Yes, you are wasting JVM cycles having all those
wasted threads. Threads aren't free, inexhaustable sources of compute power
that some people assume (I'm not saying you're one). All these threads do
share a single OS process and CPU. The JVM has to check all these all the
time to see if they have something to do. I recommend configuring the
server to run about 15 or 20 execute-threads.
I see only one thread waiting on Oracle to return data, so I don't think this
is a JDBC issue necessarily. What I do see is lots of threads trying to operate
on a Vector, all being blocked, or at least serialized by the lock this thread has, below.
Is the server hung at this point, or just slow?

You generally need a lot of data to find the performance problem in
a distributed system like this.Understood, but I was hoping that someone would recognize my description
as the "signature" of the locking problem with the OCI driver that Sun
describes.
It's very easy to switch to the Thin driver so you might as well
try it.I had hoped so, and in most cases, you're likely correct. Unfortunately,
the OCI driver is a touch more permissive than the thin driver. Some
errors (too many bind parameters) have crept in to our code that don't
cause problems for the OCI driver, but cause exceptions to be thrown by
the thin driver. In this particular case, I'm trying to solve a problem on
a production system - fixing the code there isn't an option (we are
switching to thin driver in our next release, so we are fixing these
problems).
If that doesn't help, I would suggest inserting some timing logic
in your code. In particular, I'd want to know the time a request
entered apache/tomcat, left apache/tomcat, entered WLS, left WLS
(to go to the database), returned from the database, left WLS, got
back to apache/tomcat, and finally left apache/tomcat to return the
response. With information like that, you should be able to narrow
down the problem a bit.In the next release, this is a good idea, and we'll probably do something
much like this. Unfortunately I can't make changes to the code on the
production site, so I have to rely on more passive methods of data
collection for the moment.
"Slava Imeshev" <[email protected]> wrote in message

There can be other reasons for bad performance ranging from
serialized access to singletons to inefficient queries to
server mis-configuration. I have some doubts that oci driver
would affect performance at low loads.I don't see any evidence of serialization blocking, except for the
interesting locking issue that I mentioned in the original message (a
PeerGoneListener table maintained somewhere down inside WLS).
I'm certain that inefficient queries play a large role in our
performance problems.
Service mis-configuration could very well play a role here. Note for
example the large number of blocked idle execute threads in the thread
dump below. Clearly this instance has way too many execute threads. Not
knowing the internal architecture of WebLogic Server, nor the
implementation method Sun used for monitors in Solaris JVM 1.4.2, I don't
know how much of an impact an excess of execute threads has on
performance. Anyone?
Could you post a questionable thread dump here?See the bottom of this message. The dump has been "blinded" to remove some
customer-specific information.
Also, what's the load in terms of number of concurrent users
and requests per second?At peak load, there are about 60 users logged in, of whom only about 4-12
actually do much. The number of requests per second is very peaky, and
varies from about 1-10 per second. The complexity of requests also varies
wildly.
I've attached a thread dump from a point in time when the WebLogic Server
instance was taking about 30% of the CPU.
Any and all ideas are appreciated.
