Petstore Oracle Database Exception

To whom it may concern,
I recently installed WebLogic 7.0. It worked just fine with the pointbase database
connection. The petstore example worked.. As soon as I began setting up weblogic
with an Oracle database, I began running into problems. Here is what I do know
- Connection to the Database works
- utils.dbping to database works
- Configuring Weblogic to use database connection fails.
Currently, I am stuck trying to find why the following exception is being thrown:
Unable to deploy EJB: ContactInfoEJB from suppPOEjb.jar:
weblogic.ejb20.WLDeploymentException: Incorrect DataSource type
detected. The DataSource with JNDI name 'datasource-petstoresupplierPool', specified
in the RDBMS deployment
descriptor for the EJB 'ContactInfoEJB', is not a TXDataSource.
The EJB Container requires a TXDataSource to be specified for
transactions to be managed correctly.
at weblogic.ejb20.cmp.rdbms.RDBMSPersistenceManager.verifyTXDataSource(R
DBMSPersistenceManager.java:977)
If you can shed some light on why this might be happening or point me to documentation
that could shed light on how to properly configure the petstore example, that would
be fabulous. I have included the installation notes we performed to this point.
We will continue to locate information regarding this issue. Thank you in advance
for your help.

I think that you have to install Xorg (or XFree, whichever X environment redhat uses) related packages.
They seem to be missing or not completely installed.
I don't remember which specific package contains "libXp" nor its dependencies... so i'd recommend you to install them all.
Good luck!

Update MRP Exception Messages...in Oracle Database

Hi All,
I am working on MRP Exception Messages.
I am using the BAPI_MATERIAL_MRP_LIST for my MRP Messages.
For the above BAPI The Inputs are 1.Material Number 2. Plant.
I have the Plant and Material numbers (57,000 i inserted using BAPI_MATERIAL_GETLIST) Tables With Data in my Oracle Database.
I would like to update the MRP Messages Table in in my Oracle Database.
My logic is I took the plant numbers and put into the repeater and the same Material too. I am giving linking the both to BAPI inputs,material and Plant. Is it right what I am going?
Can you give some ideas how to do it.
Thanks
R M

I think this is a duplicate of your other MRP Exception Message. Please close this one since the other one is receiving all the responses.
Thanks,
Mike

Getting TXN timeout exception when getting an XA Oracle Database Connection

Running WLS 8.1 sp5 on Linux in a Cluster (4 servers)
          Using Oracle 10.2.0.2.0 Thin XA driver
          Running Oracle Datbase 9.2.06 or 9.2.07; I think
          I am getting the SQLException: Unexpected exception while enlisting XAConnection java.sql.SQLException: Transaction rolled back: Transaction timed out after 31 seconds
          It fails at: weblogic.jdbc.jta.DataSource.enlist(Lweblogic/transaction/Transaction;)V(Optimized Method). The exception occurs on all 4 WLS instances at the same time.
          Stack trace at bottom. This problem seems to occur on and off at about the same time. We have not been able to see other jobs that would affect it during this time.
          - Max Pool Size = 25
          - Current and High Connections = 5
          - Num Unavaiable = 0
          - Failure to Reconnect = 0
          - Connection Delay ranges from 57 to 126 milliseconds
          The problem occurs within an MDB. The MDB gets a msg from the JMS queue, fires off an SMTP msg, and tries to update the database and fails due to the timeout on enlisting in the XA transaction.
          Any thoughts on what to look for? Read the info at http://edocs.bea.com/wls/docs81/faq/JTA.html#738205. Is it talking to the Oracle database to enlist. Since occuring on all 4, there is a central place it's failing and I guess the database is a start.
          Thanks. Later...

          Hi. At that moment the issue, whatever it is, has already happened.
          Something in the processing of the transaction to this point has
          already taken longer than you have specified that a transaction
          must complete in. Ideally we'd like to see the JTA/JDBC/2PC debug
          logging turned on, so we have lines with timestamps for every
          step in your tx.

Error in CLOB datatype for transfering data from Excel to Oracle database

Am using excel sheet as source and Oracle as target Database.
For all tables the operations works smoothly except for tables containing CLOB datatype.
Initially i have used SQL Developer to transfer some data into excell sheets, now i want to transfer those file's data into another Oracle Database.
What other options do i have?
Is excel not the right tool to transfer CLOB datatypes?

well,
I couldn't suggest an excel to do it...
You can go from Oracle to Oracle with the PL/SQL IKM. It works fine.
Does it help you?

Oracle Database 10g relase 1 Installation Problem on RHEL 3 ES

Dear all
I'm trying to install oracle database 10g r1 X86_64 on Intel Xeon Machine with EM64T technology with RHEL 3 ES update 2 X86_64 edition. The problem is described below :
Oracle OUI .runInstaller collapsed with such a following error:
An unexpected exception has been detected in native code outside the
VM.
Unexpected Signal : 11 occurred at PC=0x8077470
Function=[Unknown.]

Is there anyone can help me ??

Check pushitz website and ensure that you have all the required rpms installed properly.
Check the log files in the installation directory. That should give some more details as to what exactly is going on.

Memory issue in oracle database 11g ...

Hi All,
I have installed oracle11gR2 on Linux (CentOS 5.5)... SErver has good amount of HDD - 669G and 16G RAM. I have two database running on this server.
I am getting out of memory error and end user also complains about dB is very slow... I have configured memory and SGA parameter in both the database and total allocation of memory and SGA maximum size 7.5G. So I assuemd that oracle database used RAM from whatever we configured in memory maximum parameter , in my case I have allocated upto 7.5G but when I run top command I can see almost 16G is in used and only few mbs left...
can anyone suggest me my assumption about memory allcoation to database is correct or not ? or when I allocated memory to database (using memory max parameter) then why top showing all memory in used. This is database server and no other process is running except oracle.
Thanks in advance...

Just enable AMM as below and forget the nitty gritties of setting lots of memory parameters ;-D
ALTER SYSTEM SET MEMORY_TARGET=6G SCOPE=SPFILE; --select the amount of memory as per your need

Oracle Database upgrade to 11G (Host_Command Issues)

Sorry I'm posting this again. Original post in Database - Upgrade. I'm not getting a lot of clicks in that category
We recently upgraded to Oracle 11g (Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production). Our PL/SQL release: (PL/SQL Release 11.2.0.2.0 - Production). We use a lot of host commands inside our PL/SQL stored procedures. One of these included fetching data from an external server and pushing the data into Oracle Tables.
Most of this process is running fine, except the execution never completes. There is no issue data wise. It's just that the Host_command doesn't receive the completion status and seems to be running even though there's nothing going on in the background.
The Oracle e-business suite's concurrent program based on this stored proc also never completes, though it doesn't do anything in the background. For testing purpose, our DBA used 2 insert statements one before and one after the host_command. The insert before the host_command worked but not the one after. Please help! This is happening after we upgraded to 11g 3 weeks ago!
Thanks, Naveen Gagadam.

Pl do not post duplicates - Upgrade to 11g, Host Command Inside Stored Proc doesn't end.
I have moved your duplicate post to the EBS forums

Difference in select for update of - in Oracle Database 10g and 11g

Hi, I found out that Oracle Database 10g and 11g treat the following PL/SQL block differently (I am using scott schema for convenience):
DECLARE
  v_ename bonus.ename%TYPE;
BEGIN
  SELECT b.ename
    INTO v_ename
    FROM bonus b
    JOIN emp e ON b.ename = e.ename
    JOIN dept d ON d.deptno = e.deptno
   WHERE b.ename = 'Scott'
     FOR UPDATE OF b.ename;
END;
/While in 10g (10.2) this code ends successfully (well NO_DATA_FOUND exception is raised but that is expected), in 11g (11.2) it raises exception "column ambiguously defined". And that is definitely not expected. It seems like it does not take into account table alias because I found out that when I change the column in FOR UPDATE OF e.empno (also does not work) to e.mgr (which is unique) it starts working. So is this some error in 11g? Any thoughts?

It seems that my question was answered here - http://stackoverflow.com/questions/2736426/difference-in-select-for-update-of-in-oracle-database-10g-and-11g

The behaviour seems like it really is a bug and can be avoided using non-ANSI syntax. (It makes me wonder why Oracle maintains two query languages while dumb me thinks that this is just a preprocessor matter and query engine could be the same).

How to insert a image file into oracle database

hi all
can anyone guide me how to insert a image file into oracle database now
i have created table using
create table imagestore(image blob);
but when inserting i totally lost don't know what to do how to write query to insert image file

Hi I don't have time to explain really, I did have to do this a while ago though so I will post a code snippet. This is using the commons file upload framework.
Firstly you need a multi part form data (if you are using a web page). If you are not using a web page ignore this bit.
out.println("<form name=\"imgFrm\" method=\"post\" enctype=\"multipart/form-data\" action=\"FileUploadServlet?thisPageAction=reloaded\" onSubmit=\"return submitForm();\"><input type=\"FILE\" name=\"imgSource\" size='60' class='smalltext' onKeyPress='return stopUserInput();' onKeyUp='stopUserInput();' onKeyDown='stopUserInput();' onMouseDown='noMouseDown(event);'>");
out.println("   <input type='submit' name='submit' value='Submit' class='smalltext'>");
out.println("</form>"); Import this once you have the jar file:
import org.apache.commons.fileupload.*;Now a method I wrote to upload the file. I am not saying that this is correct, or its the best way to do this. I am just saying it works for me.
private boolean uploadFile(HttpServletRequest request, HttpSession session) throws Exception {
        boolean result = true;
        String fileName = null;
        byte fileData[] = null;
        String fileUploadError = null;
        String imageType = "";
        String error = "";
        DiskFileUpload fb = new DiskFileUpload();
        List fileItems = fb.parseRequest(request);
        Iterator it = fileItems.iterator();
        while(it.hasNext()){
            FileItem fileItem = (FileItem)it.next();
            if (!fileItem.isFormField()) {
                fileName = fileItem.getName();
                fileData = fileItem.get();
                // Get the imageType from the filename extension
                if (fileName != null) {
                    int dotPos = fileName.indexOf('.');
                    if (dotPos >= 0 && dotPos != fileName.length()-1) {
                        imageType = fileName.substring(dotPos+1).toLowerCase();
                        if (imageType.equals("jpg")) {
                            imageType = "jpeg";
        String filePath = request.getParameter("FILE_PATH");
        session.setAttribute("filePath", filePath);
        session.setAttribute("fileData", fileData);
        session.setAttribute("fileName", fileName);
        session.setAttribute("imageType", imageType);
        return result;
     } And now finally the method to actually write the file to the database:
private int writeImageFile(byte[] fileData, String fileName, String imageType, String mode, Integer signatureIDIn, HttpServletRequest request) throws Exception {
        //If the previous code found a file that can be uploaded then
        //save it into the database via a pstmt
        String sql = "";
        UtilDBquery udbq = getUser(request).connectToDatabase();
        Connection con = null;
        int signatureID = 0;
        PreparedStatement pstmt = null;
        try {
            udbq.setUsePreparedStatements(true);
            con = udbq.getPooledConnection();
            con.setAutoCommit(false);
            if((!mode.equals("U")) || (mode.equals("U") && signatureIDIn == 0)) {
                sql = "SELECT SEQ_SIGNATURE_ID.nextval FROM DUAL";
                pstmt = con.prepareStatement(sql);
                ResultSet rs = pstmt.executeQuery();
                while(rs.next()) {
                   signatureID = rs.getInt(1);
                if (fileName != null && imageType != null) {
                    sql = "INSERT INTO T_SIGNATURE (SIGNATURE_ID, SIGNATURE) values (?,?)";
                    InputStream is2 = new ByteArrayInputStream(fileData);
                    pstmt = con.prepareStatement(sql);
                    pstmt.setInt(1, signatureID);
                    pstmt.setBinaryStream(2, is2, (int)(fileData.length));
                    pstmt.executeUpdate();
                    pstmt.close();
                    con.commit();
                    con = null;
            if(mode.equals("U") && signatureIDIn != 0) {
                signatureID = signatureIDIn.intValue();
                if (fileName != null && imageType != null) {
                    sql = "UPDATE T_SIGNATURE SET SIGNATURE = ? WHERE SIGNATURE_ID = ?";
                    InputStream is2 = new ByteArrayInputStream(fileData);
                    pstmt = con.prepareStatement(sql);
                    pstmt.setBinaryStream(1, is2, (int)(fileData.length));
                    pstmt.setInt(2, signatureID);
                    pstmt.executeUpdate();
                    pstmt.close();
                    con.commit();
                    con = null;
        } catch (Exception e) {
            con = null;
            throw new Exception(e.toString());
        return signatureID;

How-To install SOAP Client Stack in Oracle Database

Hi,
1. i wrote a java clientstub that accesses a webservice.
2. all works fine if i run it from within java.
3. i then tried to port it to oracle database.
4. loading the java classes defined in the sample code works fine too.
5. i then loaded my client (wrapper and client-stub) classes and made pl/sql procedure from the wrapper.
6. i try to access the webservice
the problem:
1. if i made step 5 in SYS-SCHEMA all is ok
2. if i made step 5 in an other SCHEMA i got an exception in step 6:
java.lang.NoClassDefFoundError
the code line is pointing to: m_httpConnection = new OracleSOAPHTTPConnection();
this is located in the client-stub class constructor
there exist synonyms of all classes in the public schema.
is it a problem with priviledges, and if what priviledges are required?
if this isn't the best way to access webservices from within oracle database, what other solutions are possible?
if more information are required, please let me know
thanks
ralf

Hi,
Refer to this document for information on loading SOAP jar files to the database.
The database schema you are using needs to be granted the following permission to access the external web service
execute dbms_java.grant_permission('<dbuser>','SYS:java.net.SocketPermission','<host-name>:<port>','connect,resolve');
where, <host-name> and <port> point to the location where the webservice is running. If you are behind a firewall, use the proxy host and port here.
For more information on accessing external web service from the database refer to the samples on the Database Web Services Page
