Does oracle support TRANSACTION_READ_UNCOMMITTED level?

I am using oc4j drivers with jdbc for oracle 9i
I could not set the transaction isolation level to TRANSACTION_READ_UNCOMMITTED.
Does oracle support this transaction level ?
(SQL Server support it)
Here is the stack trace of the error:
java.sql.SQLException: READ_COMMITTED et SERIALIZABLE sont les seuls niveaux de transaction valides
java.sql.SQLException: READ_COMMITTED et SERIALIZABLE sont les seuls niveaux de transaction valides

at oracle.jdbc.driver.OracleConnection.setTransactionIsolation(OracleConnection.java:1681)
Thanks for any help...

Mahmoud,
The error message, you have posted, seems very clear -- the only valid values are READ_COMMITTED and SERIALIZABLE. This is also documented in the "Oracle9i JDBC Developers Guide and Reference", chapter 19 [Coding Tips and Troubleshooting], in the section entitled "Transaction Isolation Levels and Access Modes". Here is an excerpt:
the Oracle server supports only the TRANSACTION_READ_
COMMITTED and TRANSACTION_SERIALIZABLE transaction isolation levels
As someone who moved from Oracle to Informix, I can tell you from my experience, that different RDBMS's have the same functions, but each works differently. So while you probably needed to use the TRANSACTION_READ_UNCOMMITTED isolation level with "SQL Server", you don't need it for Oracle.
What you need to do is forget how you do things with "SQL Server", and learn how to do things the Oracle way. As you have seen, trying to transfer "SQL Server" code to Oracle doesn't always work.
The Oracle documentation is available from

Good Luck,
Avi.

Does Oracle support "imported" XML schemas

Hi,
Does Oracle support XML schemas that import other XML schemas. If so, are there any known problems ?
Thanks
John

I have the same problem:
A huge and complex .xsd-schema with several include and import statements can't be registered (all referenced documents exist in the repository):
DBMS_XMLSCHEMA.REGISTERSCHEMA(
schemaURL => 'http://www.toxinfo.org/namespaces/2004/05/Rosetta#ProtocolEmil',
schemaDoc => xdbURIType('/ProtocolEmil.xsd').getClob(),
local => TRUE,
genTypes => TRUE,
genBean => FALSE,
genTables => TRUE
causes an Error at the first import:
ERROR at line 1:

Editing the schema is not an option for me. Any ideas?

Try downloading the trial. It ought to detect that you have a 64-bit system.
You aren't using Vista, are you? PSE 13 requires at least win 7 and I think a few folks with vista have gotten a similar error message on trying to install it.

Does Oracle support downlaods?

An Oracle Support Analyst recently told me that downloads from
TechNet are not officially supported by Oracle, after I had
created a TAR for a 9i database problem which had been installed
from such a download. Unless I reinstalled from CDs they were
unwilling to progress the TAR, unless I could come up with a
fully reproducable test case which would have been difficult as
it was an intermittent problem. The question is where on OTN
does it say that downloads are unsupported and does this include
the patches on Metalink? Are Oracle effectively saying that we
shouldn't be downloading software. The problem with ordering
CD's is that they only seem to be available weeks/months after
the download is first made available and patches often need to
be installed in a hurry.

Let me try that again...

Does Oracle Support Running Oracle 10 Database on VMware ?

hi experts,
I have 10g Enterprise on a Windows 64-bit Enterprise platform.
I know this is a recurring question - whether or not Oracle really supports customers that run Oracle databases in a VMWare environment.
I found a document on My Oracle Support/metalink that is dated 2007. It says VMWare is not supported.
But I think the situation may have changed since 2007.
So can anyone point me to a document that shows whether Oracle does/does not support running Oracle databases on VMware - not Oracle's VMware product but VMWare, inc. ?
Thanks for any current information. John

Hans Forbrich wrote:
1) Oracle has their own virtualization solution;
2) VMWare is a brand, not a product. Your question is best asked in context of a product;
3) Oracle will provide you with support as long as you can reproduce the problem in a non-VM environment.
That last means - it is up to you to prove that the problem is not related to VMWare environment.I have never seen any scenario where Oracle demands you to prove that the problem is not related to VMware.
If its their suggested solution does not work, and they think i should, they want you to migrate it to a physical machine and test there, however this has never happend, at least not for us. We have around 100 databases in VMware, and the common talk (even from Oracle people that visits us) is that the document is only there IF THERE BY SOME CHANCE IN THE WORLD WOULD COME TO A PROBLEM FOR A COMPANY, WHERE VMWARE IS THE PROBLEM, AND ORACLE CANT HELP, they have to have a get-out clause in terms of support against VMware.

Does Oracle Support Searches with Sentence and Paragraph Proximity?

I have successfully used SENTENCE and PARAGRAPH special groups and the WITHIN operator to search for terms contained within the same sentence and/or paragraph. However, I also need to search for terms that are located within a variable number of sentences or paragraphs of each other. For example, I could search for the term 'dog' and the 'cat' located within 3 sentences of each other. Is this possible in Oracle Text? I have searched the documentation and I can only find the 'near' operator for searching based on word proximity. I cannot find any mention of sentence or paragraph proximity. This is a very important requirement for the system.

Good question. We are trying to duplicate the functionality of an existing system. It was written into the requirements for the new system. I've asked how important this functionality is to the actual users, but we don't have the answer to that question yet. Knowing that Oracle Text does not support this out of the box, we will certainly need to evaluate the importance of this feature and determine whether it warrants some custom development or switching to another search technology.
I've thought about using regular expressions to implement this feature, but I'm guessing that the performance wouldn't be that great and it wouldn't integrate well with other Oracle Text searches. Has anyone else used regular expressions combined with Oracle Text to implement more sophisticated searching capabilities?

How far does Oracle Support extend?

Hi,
I have a problem determining how far I am covered by oracle support in a particular circumstance. I intend to use the DMBS_LDAP package to connect to a CAS authentication server.
1. Am I covered by Oracle Support in this scenario?
2. If I am covered, to what extent?/what cover will be provided?
Thanks,
JIM

JIM wrote:
Justin and Billy, from what you have implied. Oracle will support their services to the nth degree, providing there is proof of bug.
Obviously the do not support third party tools. However, Oracle will not refuse support on the issue if I am connecting to a non-oracle product, such as in the scenario I described.Almost. You also need to show that the bug in the Oracle s/w is not caused by a "3rd party" s/w or unsupported/non-certified configuration combinations.
For example, last time I looked Oracle 11.2.x RAC was not certified for VMware. It is certified for OL5.x. So what happens regarding support when you run into a RAC error on OL5.x in a VMware VM? Had this discussion with an Oracle VP last year and he said along the lines of that support will be willing to assist, to the extent of certified o/s support, running on VMware - but should they suspect that virtualisation is the cause (or part of the problem), then one cannot expect support.
So in your case - if you do a DBMS_LDAP search and that crash and burn, Oracle will support that if it is a bug. However if you tried a funky method outside the LDAP specs against a proprietary half-baked implementation of LDAP, then you are on your own.
Anyway, that is my understanding of the issue...
FWIW, been using DBMS_LDAP for some years now against Microsoft Active Directory (authentication and SSO integration, and dealing with escalations and so on that needs organigram data) - no issues. DBMS_LDAP works fine against AD in our case.
