Oracle OCI Driver

Hi all,
We have a setup accessing an Oracle-database (9.0.1 and 9i) from a
java program using an Oracle thin driver like this:
jdbc:oracle:thin:@host:port:sid
This works fine. Now we wanted to try the OCI-driver for speed
comparision (mainly bypassing socket communication).
jdbc:oracle:oci8:@host:port:sid
This didn't work. We use the classes12.zip for Oracle 9.0.1. downloaded
from OTN. The error is:
java.lang.NoSuchFieldError: OCIEnvHandle

The last line given is the first line in our own code.
The SHLIB_PATH points to the lib32 directories. If we set them to the lib directories
the error changes to :

Any suggestions on what to check up on?
Also I'd like to know whether it is correct that the Oracle 9 driver uses oci8?

Hi Elango,
One cannot connect to the database using host:port:sid when using OCI driver. Strange.
It has to be a TNSname or a url .
jdbc:oracle:oci8:@(description=(address=(host=myhost)(protocol=tcp)(port=1521))(connect_data=(sid=orcl)))I tried this (adapted to our database of course) and also (because we have tnsnames.ora setup too):
jdbc:oracle:oci8:@tns_name
With the same effects. ('tnsping tns_name' works)
I think the problem lies somewhere else. The system doesn't even try to actually connect
before it throws that exception. Some driver incompatibility, I guess. But I don't know,
what I did wrong or where to look. Especially that 'Exec format error' is suspicious,
because we'd like to use 64bit if possible.
Also, for when this starts to work, I'd like to know how to make sure there is no socket
connection being used. I vaguely remember something like
jdbc:oracle:oci8:@beqlocal:tns_name
but I don't know the exact syntax. There are several database on that machine, so just
beqlocal wouldn't be enough, unless it also uses the environment-variable
ORACLE_SID
regards,
Frieder Schenke

Oracle OCI driver stops working after a while of disuse

I am using wl server 8.1, oracle oci driver (oracle 9i client), on solaris.
When i create a connection pool using the oci driver, it connects, and i
test it, and the tests run fine.
The Application works for a few days. Then eventually after disuse, say over
the weekend, I get exceptions in the log (the message is at end of email).
This is because it gives me a sql exception saying it cannot resolve the
service name. The database is up and running, confirmed.
I tried testing the connection pool manually through the console, and it
failed with the service name exception. But it would connect fine when i
used sqlplus to connect to the databse, using the same service name.
Why does this deteriorate over time? Is there a specific test that would
prevent this from happening?
Once i restart the weblogic server, the connection pool connects fine. But
this is not a solution, since I can't be restarting the server all the time.
Any one got any ideas?

-AyanHi. Is there a firewall between the weblogic server and DBMS? There is
a problem with OCI losing connectivity to the DBMS. OCI may be keeping
a socket open as long as the process (weblogic) is running.

ORA-01401 error on char column with oracle oci driver

Hello,
We found a potential bug in the kodo.jdbc.sql.OracleDictionary class
shipped as source with Kodo:
In newer Kodo versions (at least in 3.3.4), the method
public void setString (PreparedStatement stmnt, int idx, String
val, Column col)
has the following code block:
// call setFixedCHAR for fixed width character columns to get padding
// semantics
if (col != null && col.getType () == Types.CHAR
&& val != null && val.length () != col.getSize ())
((OraclePreparedStatement) inner).setFixedCHAR (idx, val);
This block seems to be intended for select statements but is called on
inserts/updates also. The latter causes a known problem with the Oracle
oci driver when settings CHAR columns as FixedCHAR, which reports an
ORA-01401 error (inserted value too large for column) when definitely no
column is too long. This does not happen with the thin driver.
We reproduced this with 8.1.7 and 9.2.0 drivers.
For us we solved the problem by subclassing OracleDictionary and removing
the new code block.

Rainer-
I read at
re:'ORA-01401 inserted value too large for column' - 9i that:
"This is fixed in Oracle9i Release 2"
Can you try that version of the driver? Also, does it fail in the Oracle
10 OCI driver?

Using Oracle OCI Driver 8.1.6 in Compaq Tru64 fastVM

Hi!
I try to using Oracle OCI Driver in Compaq Tru64.
I used fast VM (with -fast option weblogic startup) then the result
during populating Connection Pool, weblogic server down with core dump
I attached core file.
is there anyone in this situation?
[weblogicOCITest.txt]

Try using the 8.1.7 Thin Driver (the 8.1.6 Thin driver is buggy).

Problem in executing a SP in Java using Oracle OCI Driver...

Hi,
I have a installed the Oracle OCI driver on iPlanet Web Server 4.1. The application has been designed using the Jakarta Struts framework where the dom classes act as an interface between the database and the application(action classes). The dom classes execute stored procedures stored in an SP packages (eg. DDTS_PACK.setContact(..)). Now here's the problem. When a new record is being inserted, the dom executes the 'setContact' stored procedure using a java.sql.CallableStatement. The execution of this stored procedure is successful at times and fails at times. What could be the reason?? Could it be something to do with connection pooling. The default connection pooling class from oracle, oracle.jdbc.pool.OracleConnectionCacheImpl() is being used to get the connection. The funny thing is that the stored procedure gets executed both the time (success/failure) and returns a return status as 'N' when it fails and 'Y' when it is successful.
I would be greatful to anybody who could give a solution to the above problem. Thanks and have a great day.
Regards,
Anand

Since the pipe '|' is interpreted by the shell then you need the shell to invoke your command
String[] command = {"sh","-c","find /tmp/reports1 -name " + "\"" + "*" + "\"" + " -mtime +" + strdaysback + " -print|xargs rm -r"};
final Process process = Runtime.getRuntime().exec(command);
You should also read http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html at least twice and implement the recommendation regarding stdout and stderr.
P.S. Why are you not using Java to find and delete these files?

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?

Hi Joe,

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:

Error in configuring Oracle OCI Driver in WLS

You need to set your path to point to the <wls-install-home>/bin/oci8xx_x/
folder as well. I dont think 5.1 supports 817 type 2 driver, you may have to
use the thin driver from oracle instead.

WL5.1 with Oracle OCI driver 8.1.6 and 8.1.7

We have seen different behaviors when using WL5.1 with Oracle's OCI driver
version 8.1.6 and 8.1.7
Our application calls the same set of stored procedures, which creates in
total of 10 reference cursors
in the database (8.1.7). We close the reference cursor everytime the SP is
called.
After running the application for a while, we have the following situation:
1) Using the 8.1.6. driver, we always have (at any given time) one
reference cursor opened in the database
for each connection in the connection pool.
2) Using the 8.1.7 driver, we always have one reference cursor for each
stored procedure for each connection in the connection pool(i.e. 10 open
ref-cursor per connection).
It seems that between 8.1.6 and 8.1.7, the driver caches ref-cursor
differently. The 8.1.7 drive doesn't seem to be scalable. Has anyone
notice the change?
Is this behavior correct or configurable?
Thanks.

Memory leakage with oracle oci driver

I have developed a Solaris8 client/server application using the JAVA IDL CORBA implementation. The client sends requests to the server to update the database (database is Oracle 8.1.7 and I connect to it using oci oracle drivers). Requests are sent one at a time. No concurrent connections. I have a static connection that I establish with database once I start the server. If that connection is lost for any reason (timeout or database faliure) the application tries automatically to reconnect to database. I have noticed that if the new connection to database fails and an sql exception is thrown, memory used by the application process increases. This memory is not garbage collected so application hangs. I tried similar behaviour with the oracle thin driver and things went fine. There was no memory leakage.
I would really appreciate, if you can help me in this since I can't use the thin driver because of failover limitations.

I have noticed
that if the new connection to database fails and an
sql exception is thrown, memory used by the
application process increases.
How have you noticed this?I noticed this using the command pmap under solaris it operating system
every time I test reconnecting to database I go and check the memory used by the application before after attepmting to reconnect:
/usr/proc/bin/pmap [myapp pid] | tail -1
If I'm using normal connection then the memory will be increased by 100KB. If I'm using the OraclePooledConnection class then the increase will be something like 500KB. Again this is if still there is a problem connecting to database. If connection to database is okay then no memory increase at all.
This memory is not
garbage collected so application hangs.
Then it isn't a java problem. When java runs out of memory it throws a out of memory exception.Well I'm not saying it is a java problem for sure. I suspect that it might be oracle oci8 driver problem. I would appreciate if anyone can help in specifying teh source of the error.
I tried
similar behaviour with the oracle thin driver and
things went fine. There was no memory leakage.
I would really appreciate, if you can help me in this
since I can't use the thin driver because of failover
limitations.
I don't understand that last sentence at all.What I mean here is that instead of using the oci8 driver to connect to database I used the thin driver and kept everything else the same. I simulated the faliure to reconnect to database and based on the pmap command observations there was no memory leakage.
I want to know what is needed to be done in order to get a normal behavior once using the oci8 drivers.

How to setup Oracle OCI Driver with Kerberos Authentication in Eclipse

Hello I am trying to setup a connection to Oracle Server with kerberos authentication.
I am able to connect using SQL Developer but it seems impossible to do the same through the eclipse plugin any pointers?

Currently there is no support for Kerberos authentication on OEPE DB support. I'll open an enhancement request.

Oracle XA OCI driver

Hi All
I need to use XA compliant driver, does oracle OCI driver have an XA version.
I know weblogic has one and there is also one for oracle thin client.
If i have to use oracle XA driver then i should always use thin driver ???
Siju

I use OCI Driver and the same driver in "XA version"
It's the same, only you mjust change the configuration parameters..

For Oracle 8.1.7 do we need to any other library other than oci815_8. If so can
you send those details

Looks like you are using Oracle OCI driver and not WebLogic OCI driver so
you really dont need the libweblogicoci36.so file in your
LD_LIBRARY_PATH/PATH. Also your properties below show that you are using
thin driver url and then also oci8 url, check you connection pool setting
properly and may be try getting the latest oracle drivers.
If you are trying to use weblogic jDrivers make sure your pool properties
are set right.

OS authentication in Oracle 10g via jdbc:oracle:oci

I'm very much a newbie to Java / JDBC and I am trying, but failing, to connect with the database using OS authentication via jdbc, and hoping someone may help.
My questions are:
1. Is OS authentication supported for jdbc:oracle:oci with Oracle 10g ? I couldn't find a general statement of whether it works or not.
(NB.The only information I managed to find, on another forum, is that it should be supported but there is a bug and so it does not work, but the author did not post all of his/her platform details, so the bug may only affect his/her situation. )
2. If it is supported and works, could some one suggest what is wrong with my syntax . I could not find an example in any Oracle 10g/JDBC documentation.
The details are as follows: -
Database : - Oracle 10g Enterprise Edition 10.2.0.2.0 running on Solaris.
Development platform : - NetBeans 6.1, JDK 1.6.
Runtime environment: - JRE1.6 on Windows XP professional.
OPS$ authentication : - the OPS$ accounts have been set-up and we use these successfully for PL/SQL and SQL Plus access.
JDBC : - I can connect to the database with both jdbc:oracle:thin ( linking in ojdbc14.jar) and jdbc:oracle:oci by using username and password, so I know my JDBC library linkage is OK, eg. this works fine :
final String url = new String("jdbc:oracle:oci:" + uname + "/" + pword + "@" + environment);
where environment is the SID
I have trawled the Oracle documentation which tells me that OS authentication is not supported for Oracle 10g for the jdbc:oracle:thin driver, so I have tried to connect with jdbc:oracle:oci driver using the following code :
final String url = new String("jdbc:oracle:oci:/@" + environment);
final Driver driver = new oracle.jdbc.OracleDriver();
DriverManager.registerDriver(driver);
final Properties props = new Properties();
conn = DriverManager.getConnection(url);
but this gives the following error :
java.sql.SQLException: ORA-01017: invalid username/password; logon denied
Other info: - The tnsnames.ora file contains nothing but there are entries in the ldap.ora and sqlnet.ora files.

If you specify the SID/service_name in the url, you are attempting to connect via SQL*NET and REMOTE_OS_AUTHENT must be set to true in the database. If you are connecting from the same host the database runs on, then just leave the SID off and make sure the ORACLE_SID environment variable is set.
You can reproduce the same error you get in java with
sqlplus /@SID

Oracle OIC Driver for 10gR2

Hello,
I'm trying to connect my WebLogic 8.15 server to Oracle 10gR2 via the Oracle OCI driver (thick client). I have tried this on both Windows XP Pro sp2 and Windows 2003 platforms. I have installed Oracle 10.2.0 and inserted the ORACLE_HOME environment variable into my startweblogic.cmd script. When I test the connection pool, I get an error. Please, does anyone know how to fix this?
Here's the error:
