Autocommit error
Hi
I am trying out the J2EE example with Kodo 3.0.1 and JBoss 3.2.3 and have
come across the following problem:
When I try to create an object in the Oracle 9.2 database, I get an
exception when Kodo tries to update a row of JDO_SEQUENCE. The exception is
kodo.util.FatalDataStoreException: Attempt to update the sequence table
"JDO_SEQUENCE" failed. The sequence table is typically created when you run
the mappingtools refresh action on any datastore identity class. If you have
not run the mappingtool but want to create the sequence table, run:
java kodo.jdbc.schema.DBSequenceFactory -action add
NestedThrowables:
java.sql.SQLException: You cannot set autocommit during a managed
transaction!

and the Oracle descriptor like this

When using datasources, you should either specify a
ConnectionFactory2Name to point to a non-transactional datasource or set
the ConnectionFactory2Properties so that Kodo can create one. This is
so sequences will not be transactional in terms of the global context.

Reconnect policy with MySQL failing because of autoCommit error
This related to this issue, but I didn't see any responses to it: Reconnecting a dead connection from a UnitOfWork commit - Autocommit error
I'm testing with MySQL 4.1 and I have a reconnect policy that does the following (I believe this is a pretty standard approach):
session.setExceptionHandler( new ExceptionHandler() {
public Object handleException(RuntimeException exception) {
if (exception instanceof DatabaseException) {
dbex.getAccessor().reestablishConnection(dbex.getSession());
However, when it reestablishes the connection (and I have traced this and can verify that this code is executing and a reconnect is performed), I get the following error for any updates:
Internal Exception: java.sql.SQLException: Can't call rollback when autocommit=trueError Code: 0
at oracle.toplink.exceptions.DatabaseException.sqlException(DatabaseException.java:277)
at oracle.toplink.internal.databaseaccess.DatabaseAccessor.basicRollbackTransaction(DatabaseAccessor.java:1090)
at oracle.toplink.internal.databaseaccess.DatasourceAccessor.rollbackTransaction(DatasourceAccessor.java:486)
at oracle.toplink.internal.databaseaccess.DatabaseAccessor.rollbackTransaction(DatabaseAccessor.java:1075)
at oracle.toplink.publicinterface.Session.basicRollbackTransaction(Session.java:377)
I only have this problem with the MySQL JDBC drivers. I can continue to read normally, but I can't perform any transactions.
This isn't so much of a question about MySQL specifically, but rather a question about how reestablishConnection() connects to the database differently from my initial login using DatabaseLogin. Obviously, I don't have this error connecting normally. I only get it after a reconnect is applied.
Specific questions are: Is there another handler I can add to ensure JDBC Connections returned by ServerSession are always setAutoCommit(false)? Am I reestablishing the JDBC connections incorrectly?
NateNate,
This does appear to be MySQL JDBC specific but is most likely related to a general issue.
When the connection drops and you receive the notification through the exception handler I would typically recommend looking at the session in us (isUnitOfWork) or the query type (isWriteObjectQuery) to see if the operation that failed was involved in a transaction (UnitOfWork commit).
In these transaction cases you need to do more then just re-connect and retry. You need to ensure after reconnection that an application exception is raised so the UnitOfWork operation(s) can be retried completely. I would simply add to this case to ensure that the JDBC connection is put back in a state where it can be managed properly.
There is no special operation or any case I know of where any special auto-commit needs to be set on a connection after it has dropped and before it is re-connected.

Ineffective autocommit and no statement executing error
commit ineffective with AutoCommit enabled at script line **.
I got the above error when i executed my perl script. What does this mean?
In addition, i also got another error message"
DBD::Oracle::st fetchrow_array failed: ERROR no statement executing (perhaps you need to call execute first) [for Statement " ...my sql select"]
but when i do print out the value "$sth->{NUM_OF_FIELDS}" i get the correct number of fields.my code is
$sth= $dbh->prepare ("select ......")
$sth =->execute ();
while (@row = $sth->fetchrow_array() ) {
}Somebody asked nearly the same question Re: EMERGENCY! pl/sql syntax error!!!

FawazHi,
Have you tried to restart the SPL service again and again? And sometime i use to get these OptimizedRemoteExecuterStub.getStreamHolder(OptimizedRemoteExecuterStub.java:125): An exception has occurred calling the remote JVM exception if the machine is occupying more memory....
Try to restart it again. -
"Connection is closed" closed error while using MS Access database
We are using MS Access database in our project. Recently the database was upgraded to 2000.
After upgrading the database, I get the folowing error when getAutoCommit() is called on a connection -
java.sql.SQLException: Connection is closed
at sun.jdbc.odbc.JdbcOdbcConnection.validateConnection(Unknown Source)
at sun.jdbc.odbc.JdbcOdbcConnection.getAutoCommit(Unknown Source)
The connection is not closed explicity before getAutoCommit() is called, only the statement is closed.
This error is sporadic and occurs under load scenario only (when a lot of connections are open). Once the error occurs, all the database calls fail then onwards. The error was not occuring before the database was upgraded.
I suspect the jbdc-odbc driver. The driver might not be compatible with Access2000 database. Under load scenario, it might be closing connections automatically.
Has anybody faced similar problem before? Where can I find the compatible jdbc-odbc driver? And how to ensure that it is jdbc-odbc driver problem only?
The database verison - MS Access 2000
Java version - 1.3.1_01can i just point out that there is no support for transactions in Access so I wonder why you are calling autoCommit methods at all...

Autocommit and Cursor commit Behaviour
Hi,
I need help to set and get the Autocommit and Cursor commit behavior attributes
in Oracle.
AUTOCOMMIT:
For DDL Statement, this attribute is set while executing the OCIStmtExecute() api
as below:-
r = OCIStmtExecute(d->svc, d->sql, d->err, 1,0,
(CONST OCISnapshot *) NULL,
(OCISnapshot *) NULL,
d->transaction ? OCI_DEFAULT : OCI_COMMIT_ON_SUCCESS);
For DML Statement, from the OCI documentation the database parameter attributes
support OCI_ATTR_AUTOCOMMIT_DDL with the values OCI_AC_DDL and OCI_NO_AC_DDL.
Since this is a parameter attribute, I couldn't set using OCIAttrSet() API.
I need help in implementing AUTOCOMMIT for both DDL / DML statements.
CURSOR COMMIT BEHAVIOUR:
Similarly, I have observed that Oracle support cursor commit behavior attributes
using OCI_ATTR_CURSOR_COMMIT_BEHAVIOR and the attribute values are OCI_CURSOR_OPEN and OCI_CURSOR_CLOSED.
I have tried setting this attribute as below:-
ub1 nCommitType = OCI_CURSOR_OPEN;
oraRC = OCIAttrSet((dvoid *)d->svc, (ub4)OCI_HTYPE_SVCCTX,
(dvoid *)&nCommitType,
(ub4)sizeof(nCommitType),
OCI_ATTR_CURSOR_COMMIT_BEHAVIOR, d->err);
This always fails with the error ORA-24315: illegal attribute type.
I need help in setting this attribute using OCI.
Another approach to set Autocommit / Close Cursor attributes:-
Oracle support SET commands for autocommit and closecursor, I have prepared
and executed these set commands using OCIStmtPrepare and OCIStmtExecute api. The OCIStmtExecute() API fails to execute the below command texts.
SET AUTOCOMMIT ON/OFF
SET CLOSECURSOR ON/OFF
Is it the right method of setting these attributes?
Thanks,
Sankar.P.Hi.
You are trying to commit "child" information before your Parent information is commited.
Can you describe how you dragged & droped your views?.
Dragged relationship views or single views?.
Can you put output log with jbo with FINEST level?.
To find a solution try next solutions:
1) Disable "strong" association between your parent-child entities. To achieve it follow next steps:
- Go to your "Assoc" that describes your foreign key.
- In "Realtionship" tab, "Behaviour" disable "Composition Association".
Image: http://1.bp.blogspot.com/-Em8NZvjOUzo/T_NQbJTcLjI/AAAAAAAAAm4/hPsDwtEhJQ4/s1600/4.png
2) Drag and Drop correct views as a Master-Detail (cascading views in your Data Control).
http://2.bp.blogspot.com/-1By5vNNGMFQ/T_NQdYzexKI/AAAAAAAAAnE/DGn7Gr0RSDw/s1600/6.png (in spanish).
In the image, drag & drop PortalwebView2 is the correct way for Master-Details tables. Probably you dragged PortalwebView1 that have dependecy to master table.
Steps that you have followed:
- Drag & Drop dependen View Object as a Master-Detail with two tables.
- Add Create operations from these views to create Rows.
- Add Commit general operation from Data Control.
Try to drag & drop Master-Detail views correctly before disable association.
PD: To try your model faster run Model project instead of your application.
Regards.

Dg4odbc to MySQL update errors: "does not support IS NULL in this context"
I am having a problem with 'where x is null' clauses in update statements to MySQL from 11g, using dg4odbc. Updates using the clause 'where x is null' return errors like this:
ORA-02070: database PLAZAHOST does not support IS NULL in this context
The rejected queries never get to mysql. Furthermore, I noticed that select statements with 'where x is null' show up in the mysql query log with the where clause stripped out, although correct results are returned to SQLPlus. It looks as though 'where x is null' is stripped off by dg4odbc, which subsequently applies a secondary filter to the results received from MySQL.
Note, both statements above work properly when issued from the MySQL client.
Has anybody seen this? It's a big problem for me, but I can't find any references to other people having the same problem, so I assume I've got something misconfigured -- but I don't know what.
I'm using MySQL ODBC 5.1 Driver, MySQL 5.1 Community Edition, and Oracle 11g R1 all running on a 32-bit Windows server.
Thank you -- rick

So thze select will work as it is handled internally in the Oracle database. This also means as But "is null" isn't sent to the foreign MySQL db the update clause will fail with ORA-02070: database PLAZAHOST does not support IS NULL in this context

BDB vxworks 6.6 kernel port error
Hello,
I have Berkeley DB 4.7.25 compiled in kernel. When I try the example in txn_guide.c, I have got the following error:
Error opening environment: S_dosFsLib_FILE_NOT_FOUND
I'm all done.
value = 10 = 0xa
I traced the source code it fails in __rep_reset_init() when it tries to open file __db.rep.init. How can I fix this? Thanks.
Allan
#ifdef HAVE_REPLICATION
if ((ret = __rep_reset_init(env)) != 0 ||

Have I missed anything? Thanks.

Thank you so much for your response. I did test my database source from console and on the console it reported the test was successful, where in the admin logs has same exception logs. I did try creating a non XA connection and it did not have these errors. But my application did raise same exception while doing transaction.
The application has around 250 EJB's that are written long ago and they all comply to EJB 1.1 spec. I am in the process of investigating the level of support for EJB 1.1 in Weblogic 11g.

I am using Oracle Driver and try to delete a record in the database, fail
error occurs, saying "Invalid operation on read only resultset". But I have
already set the resultset as updatable, what am I missing?
Please give me some hints?
statement = connection.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,
ResultSet.CONCUR_UPDATABLE);
resultSet = statement.executeQuery("Select * from emp");
... // move to a record position
resultSet.deleteRow(); // Error occurs when I perform this operationNo, closing has nothing to do with committing!
If you have done nothing like
"connection.setAutoCommit( false)", then you are in
AutoCommit mode, means each stattement is handled by
JDBC as a 1-step-transaction and automatically and
immediately commited.By default, new connections are in auto-commit mode. The commit occurs when the statement completes or the next execute occurs, whichever comes first. In the case of statements returning a ResultSet, the statement completes when the last row of the ResultSet has been retrieved or the ResultSet has been closed.
So, closing has an effect. Please look at the thread

VikashDo you have a supported version of the Oracle client installed on the machine? If so, were the relevant environment variables set in the global environment/registry before the TimesTen Data Manager service was started? Generally, if you install Oracle, or the Oracle client, after installing TimesTen then you must reboot the machine, or at least stop and restart the TimesTen service, for the new environment variables to be picked up.
