Error starting Oracle BI Java Host service

Hi,
We are facing some issue while starting the Oracle BI Java Host service. It throws the following error.
This application was working properly till some 2 days back and suddenly it has started giving this error. We have not updated any software. The host machine is Win XP.

It also mentions about the buffer space....could that be a reason for this.
By the way, I forgot to mention, this deployment is in a VMWare (with XP as OS) which is hosted on Windows Server.

Need Expert Advice regarding oracle and java objects

In our project, we are submitting data for many screens at a time. Some screens will have a list of records to be submitted. There is also some hierarchy among the data up to 4 levels.
In such a scenario, we need to know the best way to exchange data between Oracle and Java. Currently java holds the data as objects, where each object may contain an array of next level of objects in it.
Is it best approach to pass the entire data with hierarchy to Oracle using nested table approach and internally oracle handling the data? Is there any other way to do this?
Also in some scenarios we need to pass the entire information for all the screens in one shot with the hierarchy. So we need to know a solution for that also. Could you please help us in this regard?

Oracle BI Java host not starting for Windows 7 64 bit

Hi,
I am struggling to start "Oracle BI Java host" on my Windows 7 64 bit machine. All other services - BI Server, Presentation Server and even OC4J works good.
BI Version: OBIEE 10g EE - 10.1.3.4.1
I have checked these places:
1. Environment variable: C:\Java\jdk\bin;
2. Instanceconfig.xml: *<JavaHome>C:\Java\jdk</JavaHome>*
3. Java verision: *6.0.230.5*
Can anyone help me to identify and solve this issues.
Thanks,
Yar.
Edited by: Yar on Mar 9, 2011 7:11 AM

Hi Yar,
You can try changing the Heap memory allocation parameter for Javahost at <OBI Install Directory>\instances\instance_Number\config\OPMN\opmn\opmn.xml file...
Search for -Xmx1024M and replace with -Xmx768M, save the file and Start the JavaHost, it should work.

Oracle BPM Java API - getting informations about process activities

Hi
I have a problem with Oracle BPM Java API, can someone help me?
I have a business process project deployed in Oracle SOA Suite and I need to get some informations of my process programatically via Java API.
Basically I need to get informations about process activities and the corresponding human tasks referenced by these activities.
I'm able to get the HumanTasks of my Business Catalog and also to get the Activities of my Process, but the relationship between them is null.
I did some tests, below a piece of code of my test:
IBPMServiceClient bpmServiceClient = BPMConnectionUtil.getBPMServiceClient();
IProcessMetadataService processMetadataService = bpmServiceClient.getProcessMetadataService();
IProcessModelService processModelService = bpmServiceClient.getProcessModelService();
List<ProcessMetadataSummary> processMetadataSummaryList =
processMetadataService.listProcessMetadataSummary(BPMConnectionUtil.getBPMContext(), "processNameOrId to find", "processName", "ASC");
if (processMetadataSummaryList == null || processMetadataSummaryList.size() == 0)
return;
ProcessMetadataSummary processMetadataSummary = null;
for (ProcessMetadataSummary summary: processMetadataSummaryList) {
if (summary.isIsDefaultRevision()) {
processMetadataSummary = summary;
break;
if (processMetadataSummary == null)
processMetadataSummary = processMetadataSummaryList.get(0);
IProcessModelPackage pack = processModelService.getProcessModel(BPMConnectionUtil.getBPMContext(), processMetadataSummary.getCompositeDN(), processMetadataSummary.getProcessName());
oracle.bpm.project.model.processes.Process process = pack.getProcessModel();
Sequence<UserTask> activities = process.getActivities(UserTask.class);
for (UserTask activity: activities) {
System.out.println("Human Task: " +activity.getHumanTask()); // <<<<<<<<<<<<<<<<<<<<---------------------------- here is the problem. the human task is null, but my activity have a task associated
There is another way to get this information?
Thank's

Hi,
I understand that you have raised a SR for this issue which is being worked upon by our team.
Additionally, please note that the "Closed connection" error typically happens because a timeout parameter of some sort timed out the connection. This could be a parameter specified in your datasource, in your application code, or network (such as a firewall).
You may also want to -
1. check your database to be sure it is not timing out connections.
2. Make sure your network is running efficiently and that it can provide fast connections,
3. Check your Java Virtual Machine (JVM) Code Cache For Oracle Enterprise Data Quality for any memory related issues

New in Oracle and Java

I used Sql Server and .Net for developing application to now. I switch to Oracle and Java recently. I have installed Oracle 11g. What I need to start developing aoolication with Java and Oracle?
Has Oracle a graphical interface like MS Sql Server? how can I install them? What Developing Environment You suggest for Java? I am familiar with eclipse.

I switch to Oracle and Java recently. I have installed Oracle 11g. What I need to start developing aoolication with Java and Oracle? Starting basics.
1. Learn basics of java
2. Learn basics of Oracle
3. Learn JDBC which allows you to code in java and talk to Oracle.
Do not attempt step 3 until you have complete 1 and 2.
Has Oracle a graphical interface like MS Sql Server? That would be a Oracle question rather than a java question. There are other forums on this site specific to Oracle.
Myself I just use sqlplus.
how can I install them? Huh? Just like you install anything else.
1. Acquire appropriate software
2. Read documentation
3. Install
4. Look for post install options that might be relevant.
What Developing Environment You suggest for Java? I am familiar with eclipse.I presume that you mean that you know eclipse exists for java rather than that you have used it before.
Since you are probably used to using Visual Studio, then you probably want an IDE. Eclipse will suffice for that.

Requirements to become an Oracle certified Java application

Hi everyone,
I want to know any information on how to become an Oracle certified Java application for the company I work for.
Technologies involved are Java and Eclipse.
any information or contact you can provide will be highly appreciated.
Best regards,
Sebastian

My suggestion is:
Consider First:
1) The exam 1z0-051 which should demonstrate your SQL skills.
2) The exam 1z0-047 which should earn an SQL Certified Expert Certificate.
Beyond that you will need to become more familiar with PL/SQL and go towards a PL/SQL developer OCA then OCP
I believe the following thread is relevant 1Z0-146
Read the blogs/FAW at the top of the forum, and become familair with the oracle education certification pages.
You may also seek out some the the '2-day' training as well.
Hoep this helps.

Oracle Reports Java API link Error

The Oracle Reports Java API link on the Oracle Reports page produces an error.
http://www.oracle.com/technology/products/reports/htdocs/getstart/docs/index.html

1) In Oracle Reports *10g*, Reports services are exposed as a webservice. Though it does not contain all possible actions, you can use it to run report, get job info and some other operations . [ Other than this there is no exposed java API yet ]

Oracle BPEL Java Client API: Reading Configurations dynamically

We have a requirement to use Oracle BPEL Java client API to control the BPEL instances at the runtime, from an ADF BC Application. is there any possibility to read the configurations/properties that are required to look up (using 'oracle.soa.management.facade.Locator' ) the BPEL Process Manager/Server from connections.xml/adf-config.xml ?
In other terms, as we need the details like the bpel server URL, security credentials..etc to lookup the BPEL server and instances using the BPEL java client API, how can we read these details from the ADF standard config files like Connections.xml/adf-config.xml instead of hard coding them in the Java program.

Are Oracle spatial java libraries redistributable?

Hi,
Do you have any idea about Oracle's policy on distributing Oracle Spatial Java Class Libraries? Can our software that is targeted for commercial purpose distribute it?
We are using these SDO java libraries.
oracle_sdo.jar
sdoapi.jar
sdogr.jar
sdonm.jar
sdotopo.jar
sdoutl.jar
Also if redistribution is not allowed, can our users having Oracle DB license, copy these libraries from their Oracle DB machine to the machine where our product is installed.
Please guide us to appropriate web link on this topic. We could not get clear information by going through Oracle sites.
Thanks in advance,
Subrahmanyam.

Go to: http://www.oracle.com/technology/software/products/spatial/index.html
Then click one of the downloads and you get the "Oracle Technology Network Development and Distribution License Terms". The second box covers the distribution license.
I'm sure that its covered in there .... Lots of Legal Mumbo-Jumbo ...... But it contains this line:
"You may also distribute the programs with your applications to your customers."
So it looks like "Yes" is the answer to your question !

Where's the Oracle Forms Java API documentation for 11g?

Hi,
Can anyone point me in the direction of the Oracle Forms Java API documentation?
The only thing I can find is this: http://www.oratransplant.nl/1012jdapiDoc/oracle/forms/jdapi/JdapiModule.html but this seems to be for 10.1.2 and it doesn’t correspond to the version I’m using (11.1.1.3).
Help appreciated,
Donal.

i couldn't find the api either however if you implement the class you will simply get compiler errors explaining what you left out.

any sax parsers?What version of Java are you using? With Java 1.4 the XML parser is included in the SDK / JRE.
If you're using an older version of Java, go to http://xml.apache.org and get the Xerces parser.
