JDeveloper 10.1.2 and Oracle 9.0.1.0.1 connection problem

I have a problem with connection to database. When I used JDeveloper 9.0.5 it was ok, but after intalling new JDeveloper I can't connect to db. When I try, it writes
ORA-12705 invalid or unknown NLS parameter value specified
Should I use old JDBC driver? What ca I do?

Please refer to a previous post.
ORA-12705: invalid or unknown NLS parameter value specified

JDeveloper 9.0.3 and Oracle Database 10g

I currently support a project using JDeveloper 9.0.3, and the client is mandating that we upgrade our database to 10g. Am I going to be required to upgrade to JDeveloper 10g, too? Or is JDeveloper 9.0.3 compatible with a 10g database?
Thanks for your help!

Oracle JDeveloper 9.0.3 may be used with Oracle database 10g.

Windows 2000 and Oracle 8i (8.1.6) In stall problem

Hi,
I have installed oracle 8i on a windows 2000 server. I have problem configuring a client machine to access the oracle database using service names.
I configured the service name using net8 assistant. When I try to access the database it gives me a TNS:Protocol Adapter error.(ORa 12560).
I spoke to some dba and they said its windows 2000 problem.
I did not have problems configuring a service name from the same client machine to a oracle database installed on windows NT(service pack 5).
I am able to access the database on windows 2000 through sql plus/other oracle application after I configured a service name using TCP/IP protocol.
I also able to access oracle databases installed on other windows nT machine from the Windows 2000 server client apps.
any suggestions ?
Thanks

Oracle is a pain in the butt, I'm in the middle of trying to install it too.. I've not come across that error, but it'd take to long to list the other errors I've had too!!
Dya know what order the packages should be installed in??
thanks

Thank you for your understanding!welcome to the forum,
what is your operating system name and version?
check
$lsnrctl status
if the listener is down
start the listener
$lsnrctl start
also check the database is up and running.
and try to connect with correct username,password,role (normal or sysdba) hostname or IP, port number, SID or service name.
Good Luck.

All of a sudden phone is running slow and the hourglass is on a lot / connectivity problems

I have deleted a ton of stored info and have plenty of space. It was running fine until Monday when I had to switch email carriers. I tried to link to my computer to update and it is doesn't seem to be doing anything. It says it's connected, but the files are not trasferring. Also when I updated the software to 4.7 the email icon was gone on the desktop manager. HELP!
Solved!

Z30 and JBL Synchros Reflect BT Sport bluetooth connection problem - lagging

Hi, I purchased a JBL Synchros Reflect BT Sport bluetooth headset, connects well to Z30, but my problem that if I put the phone next to me and I am moving next to the phone (like in gym) lots of times it looses the bluetooth connection and music is lagging. When I return to the former positition during gym, I heard the music again. Same problem when I have the blackberry in the backback and want to hear it. Sometimes music lagging heavily. I tried the headset on different phones without any problem. Lol, if I put one hand onto the headset and put the other hand between the phone and the headset and move my hand between the phone and the headset, the music starts lagging. The phone is next to me, so no real distance. If I move the phone position (for example face down) the problem stops on that position and start from another position. Maybe the phone does not send the Bluetooth signal well? I guess I have 2 high end product: JBL is not a no name manufacturer as well as the Blackberry. I can expect a professional result. Blackberry Protection is on, music is on the SD, but the phone is encrypted - only phone, not SD - but I dont think this is the source of the problem.
Thank you!

You need to put the Sennheiser and the Sony into Pairing mode. You may have to reset them if their Pairing memory is full.

Deploying from JDeveloper 10.1.3 to Oracle AS 10.1.2

Hi!
I use JDeveloper 10.1.3 and Oracle Application Server 10.1.2.
When I want to deploy my application (TopLink + EJB Session Bean Facade + ADF Faces) from JDeveloper to Application Server an error occured:
---- Deployment started. ---- 16.05.2006 14:02:13
Target platform is Oracle Application Server 10g 10.1.2 (for Windows) (OracleAS10g).
**** Oracle Application Server 10g 10.1.2 (for Windows) only supports ejb version 1.1 and 2.0. Project DataModel.jpr makes use of a different version and is therefore not supported.
Elapsed time for deployment: 21 seconds
#### Deployment incomplete. #### 16.05.2006 14:02:34
Question: Is there an way to deploy my application to Oracle Application Server 10.1.2?

There is!
First, be sure to create an J2EE 1.3 application (ie. no EJB 3.0, no EJB 2.0, no Servlets 2.4).
Second, apply a patch to Oracle AS 10.1.2 (see http://blogs.oracle.com/olaf/2006/02/09#a40)

RE: Rel 3.0 and Oracle

Debbie,
Yes, we have the same (or similar) problem. When trying to connect to
Oracle I get some type of deserialization error & a connection is never
made. I've sent it in to tech support & I haven't heard anything back.
On a side note, I'm also having a problem on 3.0.E.0 when I lose the
initial connection & try to re-connect. The reconnect fails. We're
trying to implement the Forte Persistence Plan using the DBResourceMgr.
I've been working with Tech Support for over 2 weeks, but we still
haven't solved the problem.

To all,
We have just upgraded our development environment to Forte Rel
3.0.f.2 and
now we can no longer get a connection to Oracle 7.3.3. Has anyone else
had a
problem after the upgrade to 3.0? We are using the remote connection.
Automatic_ipc has been set to off in the sqlnet.ora Nothing has
changed on the
Oracle side or with any Oracle related environment parameters.
We have put a
problem into Forte on this also.
Basically our development has ground to a halt, so any help would
be greatly
appreciated.

To all,
Thank you all for the quick response. The problem turned out to be the
FORTE_STACK_SIZE parameter. Although we were not getting the sympton
described in tech note 10908 I decided to set the parameter to the
recommended minimum described in the tech note. After setting the parameter
we were able to connect to Oracle.
So if anyone has connection problems when upgrading, this is something to
look at even if your symptoms do not match those described in the tech note.
Thanks again,

ConnectionPool problems with WLS 7.0 and Oracle 9.2

Hi,
We are using WLS 7.0 SP4, and Oracle 9 and the Oracle thin driver type 4. In our
application on the productive system (and only there) we constantly encounter
a whole set of SQLExceptions which have all in common that the Connection from
the pool is not valid any more when the application tries to use it.
Typical, recurring error messages are:
- Exhausted ResultSet
- Connection has already been closed
- Closed Statement
- Transaction is no longer active - status committing
- NullPointerException at
weblogic.jdbc.pool.Connection.prepareStatement()
There are no special Statements which create these errors. They are spread at
random across practically every query the application creates, and the same queries
sometimes succeed and sometimes fail.
I double and triple checked that all Connections, Statements and ResultSets are
closed immediately after use. As an example, I attached a code snippet and a resulting
StackTrace which.
The problem also seems to occur only with an (unknown) minimum of concurrent usern,
since in the approval tests on an almost identical test system these errors never
occurred.
I also followed the advice from Oracle and installed the latest Oracle JDBC driver
(Oracle 10g) - to no avail.
What else can I do?
Another question: Is it correct that my Oracle JDBC driver is in the application
classpath (via a reference in the Manifest file of the application jar), not in
the system classpath? There has never been a problem with that, but in a Newsgroup
answer from Nov 10, 2003 (subject: "ResultSet closes prematurely"), Joe Weinstein
suggested to "get it listed at the
front of the -classpath argument that the startWebLogic script creates for the
java line that starts the server".
I hesitate to do so, since the driver is in a standard WebApp- directory, WEB-INF/lib.
Is it possible and safe to add a jar located there to the system classpath? If
it is possible, why is it necessary?
Best regards,
Andreas Zehrt

Hi Joe,
Your hint that there is a threading problem was right:
On further investigation of the code I found out that the class that passes the
Connection to the DAO not only stores it as a member at some point (which is not
a good idea anyway) but is also a singleton - then, of course, it's no surprise
that the Connection gets invalid in a incalculable way when concurrent threads
share it.
The singleton instantiation was not so obvious because the way of instantiation
is controlled by a configuration parameter that can be overridden at different
levels.
I changed it and the productive logfiles indicate that the SQLExceptions related
to that class have disappeared.I am happy to have helped.
So, thanks a lot for the advice.
But I am still wondering why this code has worked for so long a time with WLS
5.1 and Oracle 8 (the system has been productive for over 2 years). Even in the
approval tests with WLS 7.0 and Oracle 9, we did not run into problems, although
it was multi-user environment.Mo idea.
I still believe that there is a difference between WLS 5.1 and 7.0 in the way
it treats pooled Oracle JDBC Connections. I wished both Oracle and Bea could be
a little more explicit about those changes and possible version incompatabilities
beyond the general advice "use the latest thin driver".Though I can think of no change to our pooling which would have had any material
effect in this case, I will certainly do what I can to see that our documentation
is explicit about changes.

We also ship
an oracle thin driver, which becomes obsolete soon...
I am concerned that your code creates pool connections to be used later.
The problems
can arise if more than one thread ever gets the same connection, or if
the connection
is used in the same thread, spanning transactions. It does also seem
that there may
be a threading issue, because if two threads each call the code to create
a connection,
and two connections are made, but one over-writes the other, the two
threads can
end up using the same connection, and closing it. The over-written one
never gets closed,
resulting in that leak message you got...
Joe
The Connection parameter is opened by a business component class, ComaServiceProviderClassicImpl.It is propagated through
several classes in the business layer, but not used, until the DAOtakes it to make the query.
So, the Connection is closed where it was opened, not in the DAO class.
public class ConcernDAOImpl extends BaseDAO {
     public Collection getConcernsForIncidents(Connection conn, Collectionincidents)
throws DataAccessException, ConstraintException, ComaParseException{>
sqlMessage.append(")");
String sqlStmt = sqlMessage.toString();
PreparedStatement pstmt = null;
ResultSet rs = null;
try {
pstmt = conn.prepareStatement(sqlStmt);
rs = pstmt.executeQuery();
while (rs != null && rs.next()) {
final Concern concern =
new Concern(DAOUtil.getComaOID(rs, ComaDBNames.KDANR));
concern.setIncidentOID(DAOUtil.getComaOID(rs, ComaDBNames.KDAVGENR));
return concerns;
} catch (SQLException sqle) {
// Wrapps real SQL exception
String[] message = new String[]{sqle.getMessage(), sqlStmt};
throw new DataAccessException(ExpCode.S_ORACLE_SQL, message,
sqle);
} finally {
closeAll(rs, pstmt);
_logger.exitDebug(method);
Here, the Connection is acquired and finally closed
public class ComaServiceProviderClassicImpl {
     public void updateComplaint(
final Request updateRequest,
final ResponseSingleElement response,
final Principal principal)
throws SystemException {
try {
logger.info("updateComplaint", "store incident");
// store the incident in the database
incidentManager.storeIncident(getConnection(), updateIncident);
// reload the incident from Cache and / or the databaseto get the ContactReferences.
Incident returnIncident = incidentManager.loadIncident(//IncidentManager passes the Connection to the DAO
getConnection(), updateIncident.getOID());
} catch (RemoteException rex) {
// remote exceptions
rollbackIfNecessary();
CoreUtils.unwrapRemoteException(rex, logger);
} catch (SystemException e) {
// all other exceptions --> rollback if necessary and rethrow
rollbackIfNecessary();
throw e;
} finally {
removeConnection();
logger.exitDebug("updateComplaint");
This is the resulting StackTrace:

Rel 3.0 and Oracle

Debbie,
2.0 of Forte Utilized a specific connection String. Example efudd.MED
(WHERE efudd was the specific machine name and MED was the Oracle SID
Reference.
3.0 of Forte has changed where they are more "OPEN" and are completely
utilizing Oracle. The particular file that it looks for is as follows:
/ORACLE_HOME/network/admin/trnsnames.ora
The syntax is @[TNSResourceName
An Example would be...
@testora or @ (for a completely local connection)
Forte does a pretty good job of documenting this on page 29 of Accessing
Databases. Since we're a tool vendor we seem to run into these database
issues quite frequently. I hope the information was helpful.
Thank you,
Joe Burns
Class I.Q.
Forte Testing Tools

To all,
Thank you all for the quick response. The problem turned out to be the
FORTE_STACK_SIZE parameter. Although we were not getting the sympton
described in tech note 10908 I decided to set the parameter to the
recommended minimum described in the tech note. After setting the parameter
we were able to connect to Oracle.
So if anyone has connection problems when upgrading, this is something to
look at even if your symptoms do not match those described in the tech note.
Thanks again,
Debbie Richards

Visual Cafe and Oracle thin driver

I have created a java applet using visual cafe and oracle think
driver. The applet connects to database within the visual cafe
environment. If I try launching applet locally within a browser
I get the following error "Error:securit. Couldn't connect to
'host' within origin from 'local_classpath_classes" Any help is
greatly appreciated.

I also had this problem. Its a general security problem.
Because your trying to connect to another machine, you
must sign your applet to get full security privelages from
within your browser. The sandbox within the JVM of the browser
doesn't let you open connections to other machines.
(Although my original understanding was that if the applet
was stored locally, then you had full privelages - but it
didn't work like this for me.)
Try signing your applet.

We have a single instance SAP Netweaver environment on Oracle 11.2.0.1 database and want to migrate to Oracle 11.2.0.1 RAC and ASM. The documents are for 11.2.0.2 and later but we want a way to:
1. Migrate single instance SAP and Oracle 11.2.0.1 instance to ASM
2. Configure the environment as four node Oracle 11.2.0.1 cluster
Thus far, I have:
1. Installed clusterware 11.2.0.1
2. Installed four ASM instances
My questions:
1. We want to migrate the single instance database to same server and extend to four node cluster and ASM
However, current SID for SAP and Oracle must remain the same. The problem I have is that the target database name needs to be same as source on same physical host.
2. How would I use RMAN to migrate the single instance database to ASM for 11.2.0.1?
3. How would I use rconfig after this step?

1- We have single instance Oracle 11.2.0.1 database using file based datafiles, archivelogs, controlfiles, etc on single RHEL5 Linux host
2- We have four available Oracle 11.2.0.1 ASM instances on four RHEL5 Linux hosts
3- We have installed four node Oracle 11.2.0.1 clusterware on the above nodesAnd what is the shared storage? For RAC, all shared storage devices for the cluster need to be available and usable by all ASM instances in that cluster.
Issue- we have RAC 11.2 clusterware listener using SCAN and listeners for all four clusterware nodes.
When we try to run the following RMAN command to migrate the single instance Oracle 11.2.0.1 datafiles it fails:The failure says: "+RMAN-10038: database session for channel ORA_DISK_1 terminated unexpectedly+". And this in itself does not tell you what the actual problem encountered is.
4- How to register the single instance with all four ASM instances and network services to resolve the above issue?Register what instance? ASM does not need databases or instances to be registered. It is a storage management layer. The cluster (grid infrastructure) layer is the one that deals with the registration (and management) of the various services and resources on that grid (e.g. ASM instances, database instances, SCAN and VIP, Listener services, etc).
5- Do we need to first run rconfig utility against single Oracle 11.2.0.1 instance to register with clusterware services BEFORE using RMAN to perform the datafile migration to ASM?Never used rconfig. See Support Note +RCONFIG : Frequently Asked Questions [ID 387046.1]+ for details.
