64-bit OCI client (either 9i release 2 or 10g) questions

If we limit the size of our data types during bindings, will a 64-bit client using 64-bit OCI be compatible with a 32-bit database instance?
Also, will 64-bit OCI be able to run on a non-Itanium x86 platform?
Thanks,
Kyle

The reason for the second question is because:
1.) I really dont want an itanium processor (and neither do my customers)
and
2.) the oracle 9i release 2 documentation:
Table 1 System Requirements
Component
Requirement
Processor
Itanium 2 or higher
Operating System
Oracle9i for Windows is supported on the following operating systems:
Windows Server 2003 Datacenter Edition for 64-bit Itanium 2 Systems
Windows Server 2003 Enterprise Edition for 64-bit Itanium 2 Systems
Windows XP 64-bit Edition Version 2003
The reason for my confusion is that 'Windows XP 64-bit Edition Version 2003' is an x86 64-bit OS.

JVM Crash With Oracle OCI Client

Hi
My app is running on Windows 7 64 bit, Jboss 4.2, launched from Eclipse, and runs fine when I use the Oracle thin client (10g, 32bit). However when I try to use the OCI client, I get this:
# A fatal error has been detected by the Java Runtime Environment:
# EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x6d906f21, pid=4740, tid=5656
# JRE version: 6.0_21-b07
# Java VM: Java HotSpot(TM) Client VM (17.0-b17 interpreted mode windows-x86 )
# Problematic frame:
# V [jvm.dll+0x106f21]
I'll post the contents of the log in another message because it's too long to fit here. Using the thin client is NOT an option unfortunately as the thin driver is missing some functionality that we need to use.
I've installed the Oracle client in a folder that doesn't contain spaces, or parentheses (c:\oracle\.....) and the JDK is installed in a similar directory (c:\java\...)
I've tried both 32bit and 64 bit versions of JDK1.6 and the Oracle 10g client. I have also tried mixed mode and interpreted mode JVM (Xint) with the same results.
ojdbc14.jar is in my JBoss server's lib directory, and ocijdbc10.dll is in my path (c:\windows\system32).
Anyone any ideas what's going wrong? Been trying to fix this for days now. Appreciate any help.
Richard

Sorted it (well, my colleague did anyway). We installed a fresh version (32 bit) JDK (6u21), the Oracle 10g (10.0.3) client (32 bit) and made sure that there were no other OCI DLLs anywhere. I had some in the JBoss bin directory which I had copied in earlier that morning and forgotten about. So, the only OCI DLLs I have now are in Oracle's installation directory. Once we removed those erroneous DLLs from the JBoss directory, the server made the connection successfully. I don't full understand why, because I was getting the error earlier without the erroneous DLLs being present too, so I think there was some additional interaction going on somewhere. One other thing that may have been important is the tnsnames.ora file I had. We found a post that said the tnsnames file generated by the installer, when it only has one entry in it, can include dodgy whitespace at the end which can cause problems. So, just to be on the safe side we added a second entry (to another DB) - maybe that was something to do with it.
So, the Oracle 10g client and OCI driver DOES work on Windows 7 64 bit (at least for me anyway)

32 Bit Oracle Client Libraries on a 64 Bit Machine

Hello,
I own a 32 bit application that is running on a 64 bit linux machine currently only installed with 64 bit oracle client libraries. I requested the administrator install the 32 bit client libraries so that my application can function and they tell me that it is not possible. They cited a Meta-Link article that I do not seem to have access to, but this doesn't seem right. Has anyone else ever installed 32 bit compatible client libraries on a 64 bit machine. Thanks

On Linux (and this is only on Linux, not on Solaris and AIX !) if the OS is 64bit, only 64 bit Oracle is supported.
Check the Certify pages for Linux x86-64. This is in the critical notes :
"Linux x86-64, support on AMD64/EM64T and Intel Processor Chips that adhere to the x86-64 architecture with supported Linux releases. *Running Oracle 32-bit on AMD64/EM64T (64-bit OS) is not supported .*
Oracle 32-bit running on AMD64/EM64T with a 32-bit OS is supported, refer to platform Linux x86 for more information on product availability. "

Running in 64 bit mode with the 32 bit Oracle client installed

I have seen many postings on this issue but none of the suggested solutions have helped me.
I am running visual studio 2010 professional with SP1 on windows 7 64 bit machine. When I try to run a web service locally and call it with SoapUI, I get the following error message during OracleConnection.Open().
Attempt to load Oracle client libraries threw BadImageFormatException. This problem will occur when running in 64 bit mode with the 32 bit Oracle client components installed.
I have tried setting up the build configuration and the project settings to target 32 bit but that has not helped. I have also tried removing the reference to System.Data.OracleClient that shows being under Program Files (x86) and add a new reference to the dll under GAC_64. That too did not work.
I only have the 64 bit client installed on my machine.
Any help will be appreciated.
Thank you

1. Visual Studio any version is 32 bit ONLY irrespective of hardware or OS bits. So to DEVELOP with Oracle Client you MUST install 32 bit Oracle ODAC components. Task manager will show devenv.exe *32 (to confirm 32 bit Visual Studio application).
2. You can run your web application inside IIS/IIS Express in your PC which independently can be either 32bit or 64bit. If it is 64 bit, you MUST also install 64 bit Oracle ODAC components which means you'll have to install both 32bit and 64bit in your 64 bit Win7 running on 64bit hardware.
3. In Visual Studio if you compile with "AnyCPU" as target, the resultant binaries (Web/NonWeb) can be both 32bit or 64bit. So if target PC is "AnyCPU" or "x64", you MUST install Oracle ODAC 64 bit in the target OS if that target OS is 64bit. You don't have to install 32bit ODAC in the target PC.
4. One more catch to above scenario is the target OS could be 64bit simulated OS on a 32bit hardware. In such case you MUST install both 32bit and 64bit ODAC components.
So while you ask your network team to download ODP.NET/ODAC Components make sure you ask them to download both 32bit and 64bit. Total nearly 600MB.
Hope this helps many people out there.

XMLType inputstream on OCI client

Hi all, I have a problem using XMLType.createXML in java to create a XMLType to use as parameter in a stored procedure using OCI client (it works with thin client).
my environment (sorry if I missed something!):
Oracle db 11.1 on server, Java 1.6 and OCI client 11.1 on Windows on client.
In my Eclipse project I included the following jars:
\jdbc\lib\ojdbc6.jar
\jlib\orai18n.jar
\RDBMS\jlib\xdb.jar
\LIB\xmlparserv2.jar
the java code snippet for calling the stored procedure using the input stream:
public String putgetXMLInputStream(File testFile) throws SQLException, FileNotFoundException, UnsupportedEncodingException
     // create the input stream from the file containing XML
     InputStream br = new BufferedInputStream(new FileInputStream(testFile));
// this statement was tested with no value for "kind" parameter and with these two value too
     // "oracle.xml.parser.XMLDocument.THICK"
     // "oracle.xml.parser.XMLDocument.THIN"
     XMLType xmlDoc = XMLType.createXML(connection, br);
     // set the statement
     CallableStatement cs;
     cs = connection.prepareCall("{?=call MYPACKAGE.TESTUPLOAD(?)}");
cs.registerOutParameter(1, OracleTypes.VARCHAR);
     cs.setObject(2, xmlDoc);
// execute the statement
     cs.execute();
     // return the string
     return cs.getString(1);
same code with string:
public String putgetXMLString(File testFile) throws SQLException, FileNotFoundException, UnsupportedEncodingException, IOException
     StringBuilder contents = new StringBuilder();
     try {
     //use buffering, reading one line at a time
     //FileReader always assumes default encoding is OK!
     BufferedReader input = new BufferedReader(new FileReader(aFile));
     try {
          String line = null; //not declared within while loop
          * readLine is a bit quirky :
          * it returns the content of a line MINUS the newline.
          * it returns null only for the END of the stream.
          * it returns an empty String if two newlines appear in a row.
          while (( line = input.readLine()) != null){
          contents.append(line);
          contents.append(System.getProperty("line.separator"));
     } finally {
     input.close();
     XMLType xmlDoc = XMLType.createXML(connection, contents.toString());
     // set the statement
     CallableStatement cs;
     cs = connection.prepareCall("{?=call MYPACKAGE.TESTUPLOAD(?)}");
cs.registerOutParameter(1, OracleTypes.VARCHAR);
     cs.setObject(2, xmlDoc);
// execute the statement
     cs.execute();
     // return the string
     return cs.getString(1);
the java code snippet for establish the database connection (I know that with java 1.6 the registerDriver is not
required, I both tested with and without driver registering and it works in the same way):
// connection string: comment as required
// connection string for thin client
// String connectionString = "jdbc:oracle:thin:@mydbserver:1521:mydb";
// connection string for oci
String connectionString = "jdbc:oracle:oci8:@mydbserver:1521:mydb";
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn =DriverManager.getConnection( connectionString, "john", "tiger");
DatabaseMetaData meta = conn.getMetaData();
System.out.println("Driver JDBC: " + meta.getDriverVersion());
The PL/SQL called by java:
FUNCTION TESTUPLOAD (pDoc IN XMLTYPE) RETURN VARCHAR2 IS
msgout VARCHAR2(24000);
doc DBMS_XMLDOM.DOMDocument;
rootnode DBMS_XMLDOM.DOMNode;
fchild DBMS_XMLDOM.DOMNode;
attr1 VARCHAR2(20);
ns VARCHAR2(200);
BEGIN
ns := 'xmlns="http://www.myweb.it/static/xml/def/0.6/ns1.html" xmlns:si="http://www.myweb.it/static/xml/def/0.6/si.html"';
doc := DBMS_XMLDOM.newDOMDocument(pDoc);
rootnode := dbms_xmldom.makeNode(doc);
fchild := DBMS_XMLDOM.GETFIRSTCHILD(rootnode);
-- dom text
DBMS_XMLDOM.WRITETOBUFFER(rootnode, msgout);
-- attribute value
dbms_xslprocessor.valueOf(rootnode,'/DOC/@TYPENO',attr1, ns );
-- node name of rootnode first child
return '(' || attr2 || ' - ' || DBMS_XMLDOM.GETNODENAME(fchild) || ') ' || msgout;
END TESTUPLOAD;
Thus, the expected result is a returned varchar2 containing the value of the attribute as per XPath, the name of first child node
and the whole text of dom.
This work as expected connecting via OCI and Thin client if I create the XML starting from a string, and only with Thin client if
I adopt the input stream approach. If I use the input stream with OCI client, no error message is displayed, and no value are provided
for attribute or fchild name, but the dom text is returned.
I made test with different charset encoding for the original file (UTF-8, ISO-8859-1, with endofline in windows and linux style).
What I noticed is that in case of string and input stream with Thin client some kind of parsing occours: the returned text show some
special characters (i.e. double quote) replaced by html entity and the charset encoding in <?xml tag replaced with ISO-8859-1, more over
the returned xml is well indented.
I'm sure that I'm missing something :-)
Any hints?
TIA

visit the javasoft.com (sun site) for tutorials and training on all of the technologies you mentioned.
after understanding them, then review the oracle java roadmap found on technet.oracle.com --> technologies --> java to get an oracle perspective.
then ask the oracle technology specific questions you have.

Memory leak using 10.2.0.3 OCI client on Solaris

Hi,
We are using OCI client libraries to connect our C++ program to the Oracle Database. The program does a lot of selects, inserts and SP calls.
Oracle client and Oracle server both are 10.2.0.3.
We have been observing a memory leak of 4M bytes in the C++ program every few minutes since last few days. On debugging through Purify, libumem, and Sun Studio 12, we finally managed to narrow down the problem to the Oracle client library OCI calls.
The Sun Studio leak check shows the following -
Leak #37, Instances = 157, Bytes Leaked = 655004
kpummapg + 0x00000098

A select is executed, a resultset is fetched and the resultset is immeidately closed. The same piece of code has been running at various production systems without any problems. Most of the other sites are either 10.2.0.4 or 9i.
On searching Metalink and various other forums, I found similar issues faced in 10.2.0.1.
Could someone advise if there are any bugs corresponding to this which have been closed. Would upgrading to 10.2.0.4 solve the problem?
Thanks.

Hi,
Apparently a similar issue is being discussed over here:

Oracle 8.1.5 oci client to oracle 9i database

Is is supported to use an Oracle 8.1.5 oci client to oracle 9i
database? If not, will it work?

Ok,
so You can follow the migration path that I've indicated before:
"To do that, the simplest way., is to install 10g r2 software on the Win 2003 machine. Create the DB and create the same accounts of the 8i version.
On the 8i version, export all the schemas using "exp" utility, w/o using the DIRECT option.
Copy the generated dump files onto the Win 2003 machine and import them using th "imp" utility,
Analyze all the objects and that the migration is complete.
You shouldn't find any problem porting structures and code from 8i to 10g R2
No matters will occours, cause imp utility of 10g is backward compatible with 8i exp files
Hop this helps

64 bit oracle client VS 32 bit oracle database

Install 16 bit Oracle client on Win 2003 server

Hello,
Is it possible to install Oracle SQL* Net 2.3(16 bit) Client on Windows 2003 server. If it is then could someone give me links from where I could get more information on this (like the steps to install 16 bit Oracle client on Win 2003).
Thanks.

the 16-bit applications are not supported by Windows 2003 server x64 edition.
http://support.microsoft.com/?kbid=896458&SD=tech
I have never tried to use 16-bit SQLNet client on Windows 2003 x86. I'm pretty sure that this combination will not be supported by Oracle , athough it could work.
As far as I remember the 2.3 client was shipped with the Oracle 7.3.
here is the desupport notice for Oracle 7

This method should not be called anymore. The client was already released i

Hi,
while configuring Business Packager for Projects 50.3 fo, we made few changes in R/3 side as per the documentation. after that we are getting following error in portal
"This method should not be called anymore. The client was already released into the pool or the pool entry was deleted"
all the chages were reverted in R/3 system still we are getting the same error.
Can any one help on this issue....
Thanks in advance and for early responce higher marks would be awarded!!!..

Hi,
Well there were errors in how stop works:
"Stopping a thread with Thread.stop causes it to
unlock all of the monitors that it has locked (as a
natural consequence of the unchecked ThreadDeath
exception propagating up the stack). If any of the
objects previously protected by these monitors were in
an inconsistent state, the damaged objects become
visible to other threads, potentially resulting in
arbitrary behavior. "
I do understand that you want to have something like
killTheTreadIDontCareAboutConcequences-method, but
it's better to let all your methods that you want to
be able to terminate take a timeout argument, and deal
with the termination in the method. (Close the
sockets/streams etc that you are blocking on).
/KajThe point is, it is not always possible to make those blocking methods stop, via some magic "timeout" thingamabob. The bottom line is still that the blocking methods were written incorrectly to begin with (to possibly block indefinitely), so one cannot come up with an across-the-board solution, other than getting the root cause fixed in the first place. However, one is not always in control of fixing the root cause.

Question about 32 Bit Oracle11g Client

hi
so many downloads....... i get lost ..........
from where i can download 32 Bit Oracle11g Client for windows-7 64bit that work with Oracle 11.2.0 64bit using PL/SQL developer ver 7.1 ?
i really dont know what to download.......
thanks in advance

If PL/SQL developer is a 32 bit application, you will need the 32 bit Oracle client (even if the server is running the 64 bit version of Oracle Database). You can download the 11.2.0.1 client from the following link:
http://www.oracle.com/technetwork/database/enterprise-edition/downloads/112010-win32soft-098987.html
The 10.2.0.5 client will also work, but that is more challenging to install.

You do not need to do anything in VS. You do need to configure both tnsnames.ora files, because the drivers do not share any data.

Hi,
Based on the error message, we should confirm whether Oracle client tool has been installed on the Report Server at the beginning. If the Report Server installed is 64-bit, we should also install a 64-bit Oracle client tool on the Report Server. Besides, we
can also try to bypass tnsnames.ora file when connecting to Oracle by specifying all the information in the data source instead of using the TNS alias to connect
to the Oracle database. Please see the sample below:
Data Source=(DESCRIPTION=(CID=GTU_APP)(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST= server01.mydomain.com)(PORT=1521)))(CONNECT_DATA=(SID=OracleDB)(SERVER=DEDICATED)));

Does OCI client result cache and oracle UCP work together?

I'm using Oracle 11.2.1.0. I've set up FCF and enabled OCI result cache on server side, so on client side, I'm using UCP for failover.
this is my datasource configuration:
<Resource name="jdbc/MyPool"
auth="Container"
factory="oracle.ucp.jdbc.PoolDataSourceImpl"
type="oracle.ucp.jdbc.PoolDataSource"
connectionFactoryClassName="oracle.jdbc.pool.OracleDataSource"
url="jdbc:oracle:oci:@dbhost:1521/myDb"
user="db_user"
password="db_password"
fastConnectionFailoverEnabled="true"
onsConfiguration=""
connectionPoolName="dbPool"
initialPoolSize="5"
minPoolSize="5"
maxPoolSize="25"
connectionWaitTimeout="10000"
inactiveConnectionTimeout="120000"
abandonConnectionTimeout="60"
validateConnectionOnBorrow="true"
sqlForValidateConnection="select user from dual"
maxStatements="30"/>
I've enabled OCI client result cache.
I use /*+ result_cache */ in my query to take advantage of the result cache.
so I execute the following scenario:
i) select /*+ result_cache */ value from myTable where id=1; (this returns a result.)
ii) update myTable to set a different value for id=1 record;
iii) run select query again; (this should return a different result. oci result cache gets updated when table changes.)
if I take out
"sqlForValidateConnection" and/or "validateConnectionOnBorrow" (i.e. disable sql validation on borrow), the 2nd query after table update doesn't show the latest result. it's still showing the old query result.
is this a bug? that UCP validation on borrow has an impact on OCI result cache function? this doesn't happen if using dbcp java connection pooling with OCI result cache.

it turns out I ran the test against an oracle server that doesnt have FCF configured, nor ONS.
once i switched to a correct oracle cluster, my test passed.

Trouble connecting to 64 bit oracle client from 32 bit environment

Hi,
I have an application which connects to Oracle and an external 3ed party application via a set of APIs. We are now facing the issue while migrating our server from 2003 to 2008.
The 2003 server was configured for 32 bit and had 32 bit Oralce installed on it. It was able to connect to both Oracle and the 3ed party API in this configuration
In our New 2008 server we have installed a 64 bit Oracle however the 3ed party API is using is 32 bit. Once we use the 64 bit app poll we were able to connect to the Oracle, but the API connection fails. When we enable the 32 bit in APP Pool, wer cant connect to the Oracle client.
Could you please suggest a possible soultion for this problem?
PS:
We have tried placing the 32 bit Oracle.Data.Client DLL in the Bin folder and refered it in our project ( to avoid refering the 64 bit DLL from GAC) but this method didint work out.
We have alos tried placing Oracle Data Access Componets DLLs in Our bin as explianed in the following blog post
http://researchaholic.com/2011/10/21/connect-from-net-to-oracle-without-installing-the-oracle-client/
This also did not help us connect to the Oracle client.
Right now we have configured our new 2008 server with 64 bit oralcle client and enabled 32 bit support from APP pool.
Thanks

You can't use 64 bit client on 32 bit machine.
You can use 32 bit client on 64 bit machine via syswow64, but not the other way around.
If you compile your app with AnyCPU compile target though, it will automatically run as 32 bit on 32 bit OS, and 64 bit on 64 bit OS.
