Oracle blocked process on vmstat
Hello,
I am getting oracle blocked process on the results of vmstat b column. The run queue is fine and but the blocked process are increasing . When I checked with the forums i found out that it waiting for an I/O.
Hardware: IBBM blade
SAN - Netapp
The server is OEL 5 with Oracle 11g running on it. There is no local disk on the server everything configured as SAN with multipathing. Also along with the /boot and / partition are connected to the SAN.
Also experiencing the issues with the cpu utilization as well and the cpu utilization become 100%. And it causes for the server load to reach 15 , 25, 30. The kernel parameters are set it up as recommend by the Oracle.
This is causing issues for Oracle query. Is there any recommendation I can use to improve the performance?
The numbers in vmstat alone won't help you, as they depend on workload. As far as I know, the values won't tell you if your system or processes are working efficiently. You may have a busy process or technical issue causing a performance bottleneck, or perhaps you are overloading the machine, have run out of physical memory, etc., etc.
The bi and bo column in vmstat shows the data transfer between virtual memory and block devices. I don't see how these numbers could possibly tell you that something is wrong. Perhaps your database is performing a lot of full table scans or the DB cache is too small, etc. But then again, it depends on your tasks and workload.
I suggest to find out which processes are causing the most I/O and then analyze the processes. Process that are waiting for I/O are typically in "D" state. What is your output of the following:
<pre>
# ps -eo state,pid,cmd | grep "^D"
</pre>
If you suspect that disk access is the issue, use the pid(s) of the previous command as following to see which files are affected.
<pre>
# lsof -p pid
</pre>

Create Lead with Oracle BPEL process using Siebel CRMOD web service
I'm trying to create a lead in the siebel OD (hosted) with a oracle BPEL process and using the siebel web service (2.0). In my bpel process I've been able to
1. Login to OD and get a session id
2. create the partner link using Siebel OD (version 2.0) wsdl for Lead
3. Assign the session id to the partner link
4. Assign the inputs (lastname, firstname, leadowner, viewMode=Personal, lovLanguageMode=LDC) to lead
5. Call the leadInsert operation on the partner link
However, when I deploy and execute the bpel process it breaks after calling the leadInsert with the following error message:

Any feedback as to what I'm doing worng woull be greatly appreciated.
Thanks,
--manojHi,
We are also using BPEL to send data out to SIEBEL CRMOD.
I've created a proxy that deals with authentication and session management.
All you have to do is to deploy the proxy as a war file and refrence it as the end-point of your partner link.
Code is here:

Problem to start BPEL Console of Oracle BPEL Process Manager 10.1.3.1.0
Hi everyone!
I'm writing to yours because I installed Oracle BPEL Process Manager 10.1.3.1.0 but I can't start BPEL Console. I tried to start it by the option menu of Windows XP and by Developer Prompt, but I get a HTTP 404 Not Found page. When I was installing the universall installer told me that it wasn't possible to set ORACLE_HOME variable because it had a value older than 1023 characteres. So, I continue the installation but I can't start the BPEL Console. The Dos Console teld me sometimes when I put http://localhost:9700/BPELConsole..timed out. So, tell me how to resolve that problem.
I'll be waiting your responses.

Thanks for your responses.
Greetings.Hi,
you said:
it wasn't possible to set ORACLE_HOME variable because it had a value older than 1023 characteres
What do you mean with older than 1023 chars?
I think the easiest way is to uninstall the BPEL Console and run the installer again with correcting the ORACLE_HOME problem... -
Oracle Event Processing (11.1.1.20100416-1727)
Hi,
I have recently started working on a oracle event processing application.
In our case,we dont have a streaming data coming as input to the application but we maintain a static relational table which we need to hit every 5 seconds and check for a particular rule to be executed. Right now we maually update/insert the data now and then. So the input to our application would be a select statement from a static table. The rules executed successfully and all looks fine.
Being a developer am able to visualize the rules that I have created via the code for manipulation.
Adding to the above functionality we are in need of window/API kind of thing where the end user updates the rule regularly. Let us assume the static table contains the withdrawal amount and the end user changes the threshold withdrawal limit on daily basis.
When we open the visuallizer ,we can see our application running on the oep server and in the cql rules tab we can see the rules formed for streaming data for ex: select * from helloworldinputstream.
Is there any way to show the sql queries which we have written for the manipulation in the CQL rule tab?
Could you please help me proceeding further.
Version of CEP: 11.1.1.20100416-1727Hello,
You should install oracle software first and then launch DBCA. Once you have installed oracle software only you can crete listener using netca. Check your init.ora file (must be under
C:>$ORACLE_HOME/database/dbs or $ORACLE_HOME/dbs and local for following parameter LOCAL_LISTENER and remove it. But I recommend you to install oracle software only first and then launch DBCA.
What's your OS? Is it vista? XP?

How to install Oracle BPEL Process Manager for OracleAS Middle Tier
hi,
i need to install BPEL process manager, so i download the following file from otn
1.soa_windows_x86_101310_disk1
2.soa_windows_x86_bpel_101310
here i read the document named b28980.pdf from bpel\doc\pc.1012 to install BPEL PM
so i start to complete the pre-installation task
1.installed Oracle database 10g
2.Run the Integration Repository Creation Assistant on the Database
3.Install Oracle Application Server 10g Release3 (10.1.3.1.0) and select either the J2EE Server installation type or the J2EE and Web Server installation type. selected J2EE and Web Server installation type
and installed according to the Oracle application server installation guide.
installed OracleAS in the path : D:\product\10.1.3.1\OracleAS_1
4.Install the current release of Oracle BPEL Process Manager for OracleAS Middle Tier
here they mention to select the J2EE and Web Server installation type because that type is selected in Oracle AS installed in Oracle Application Server
so i start to install the BPEL PM by selecting the setup.exe-->and shows the location source and destination
default destination is : D:\product\10.1.3.1\OraBPEL_1 selected next on the screen
the next screen is select installation type here there are two types named
1.BPEL process Manager for Developer (371MB)
2.BPEL process manager for Oracle AS Middle tier (107MB)
i selected 2.BPEL process manager for Oracle AS Middle tier (107MB) and click next
pop up window opens with title dependencies
error:
BPEL Process manager for oracle AS Middle tier will run on top of a supported Oracle Application Server 10.1.3.1.0 J2EE server and Web Server Or J2EE server instance. this location does not contain this instance. Please select new Oracle home that contains a supported instance.
so i changed the destination path to : D:\product\10.1.3.1\OracleAS_1\BIN then also i got the same error.
please any one mention the path for J2EE and Web Server instance for installing the BPEL PM for Oracle AS Middle Tier.
Thanks in Advance
Aswath ThanigaIf you choose the developer version you will be fine.
If you have installed J2EE and Web Server installation into D:\product\10.1.3.1\OracleAS_1 then this is the location you install your BPEL PM into, not D:\product\10.1.3.1\OraBPEL_1 or D:\product\10.1.3.1\OracleAS_1\BIN.
D:\product\10.1.3.1\OracleAS_1 is what we call the ORACLE_HOME, generally we create a new home for each install, but in this case there is a dependency on 10.1.3.1 OC4J container. So it needs to be installed into 10.1.3.1 oracle home.
The bin directory is just the executables for that home, its not the actual. home.

How to install Oracle imaging & process management in windows xp prof
Hi All
I am trying to install oracle Imaging & Process management in windows XP. Please let me know whether it is possible in windows XP or not... which I couldn't able to install in XP. when I saw the Install doc, it mentioned it is possible in windows server 2003. Installation guide mentioned that we have to setup 6 or 7 different server setups.
or
If any one have I/PM installation steps for windows server 2003 Please provide the steps.
Any input would be greatly appreciable.
regards
VijayVijay,
IPM is not certified to be installed on Windows XP (as for IPM services).
It is possible to install IPM on one server machine (or two, if you need Web). First, you have to decide, which services you have to install.

Actully ,there is no BpelGroup in Weblogic. Does anybody know how to solve it ?MAke sure you have not set ANY environment variable related to Oracle / BEA / Java / LD_library path. Use the following script to unset / set the initial settings:

unset ORACLE_BASE ORACLE_HOME ORACLE_SID ORACLE_TERM
unset LD_LIBRARY_PATH LD_LIBRARY_PATH_64
unset CLASSPATH JAVA_HOME
export PATH=.:/usr/sbin:/usr/bin:/usr/local/bin:/opt/VRTS/bin

Does Oracle BPEL process manager ships jdeveloper bpel designer
I had downloaded Oracle bpel process manager and installed on my desktop but I am unable to find jdeveloper bpel designer shiped with process manager.
Could any one update me regarding the sameHi,
Follow the steps which I have mentioned.If you want to start with BPEL you can do either of the two things.
1) If you are interested in only BPEL then download and install BPEL server from oracle site. For coding you need to have Jdeveloper.
or
2) If you want to use all the components of SOA then download version 10.1.3.1 and install SOA suite. Apply Patch to upgrade version to 10.1.3.3.
After installation of server, download Jdeveloper 10g and Unzip the file to use it.
Hope I clarified your doubt.
Cheers,

How to Instantiate Oracle BPM Process Webservice from the OSB
Hi,
In our project we have one requirement i.e Instantiate Oracle BPM Process Webservice from the OSB.After register BPM service in to OSB I am creating one Message flow to instantiate BPM Process.
first call to startSession Operation, then use response of startSession operation is used as reqest for BPM process operation.
Can u tell me how do we use response of startSession operation to the request of BPM process.
Thanks in Advance.An easier way of instantiating a BPM process via a WS call is to set the authentication type to 'Username Token Profile' on your web service operation in BPM studio and then redeploy it. If you use this type of security on your bpm process operations you can start the process in one call instead of having to get a session first and then starting the process.
Once you've updating the process, re-register the new process WSDL and business service with OSB (or import it manually) and you can just call the start process operation in one request (passing a username and password using the WS-UsernameToken method) without having to get a session first.
Hope this all make sense,
Mike. -
Regarding Oracle Business Process Manager and WS-Security
Hi All,
Actually I like to invoke couple of secure services running on seperate
server runnnig JWSDP.These services are using WS-security,so I am just
wondering if it possible to call these webservices through Oracle
Business Process Manager.
As our secure services are using JWSDP so thats the reason we prefer to
use the BPEL engine which deployed on top of JWSDP so that We dont
have to confront with compatable issues among different toolkits.
So I am just wondering do you think that Oracle business process manager
ws-secuirity implementation can use the JWSDP implementation i.e
xws-security implementation,in otherwords is it possible to use JWSDP
with Oracle business process manager for using the ws-security?Thanks.
I would appreciate your help.
Kashifyes we do native in Oracle BPEL PM (username token) - as explained here

for more sophisticated ws sec stuff, pls use Oracle Webservice Manager -
What locks are required on a table when Oracle is processing an UPDATE
What locks are required on a table when Oracle is processing an
UPDATE statement?Welcome to the forum!
Whenever you post provide your 4 digit Oracle version.

What locks are required on a table when Oracle is processing an
UPDATE statement?
>
Here is a relevant quote from the 'Lock Modes' section of the doc that Ed Stevens provided
>
Assume that a transaction uses a SELECT ... FOR UPDATE statement to select a single table row. The transaction acquires an exclusive row lock and a row share table lock. The row lock allows other sessions to modify any rows other than the locked row, while the table lock prevents sessions from altering the structure of the table. Thus, the database permits as many statements as possible to execute.
>
The above describes the locks when you, the user, tells Oracle to lock the row.
