SOA Suite 11g - Connection Pools constantly getting suspended...

Hi,
I have composites, bpel processes using database adapters.
*I keep getting "+Pool mds-owsm is Suspended, cannot allocate resources to applications+" and " Pool SOALocalTxDataSource is Suspended, cannot allocate resources to applications.." in soa_server logg.*
There are no errors in db trace logs. It seems related to the WLS JDBC data sources, they are constantly getting suspended.
After a while no new connections can be created, and managed soa server hangs. Restart is the only "solution" for now...
I have increased "Maximum Capacity" on the connection pool to 300 without success.
Any ideas, pointers, help appreciated.

DB and SOA are not on same machine, no n/w issues.

Weblogic Domain not getting created in SOA Suite 11g R2

I have installed the components of SOA Suite 11g R2 (11.1.1.3) on a single Windows XP SP3 machine (32 bit) following recommended procedures. I tried to configure Weblogic server using Domain Configuration utility. After navigating hrough the wizard, no Weblogic server profile is getting created in the doamin folder. Even the WL Admin server is not getting created. The Domain Configuration utility did not throw any errors.
1) Is this problem related to Oracle repository for SOA suite 11g?
2) Can the repository schemas (Oracle) hold multiple weblogic SOA domain information?

Hi,
Weblogic servers directory do not gets created after domain creation or even managed server configuration. It will present itself only when you start the managed server for the first time, that is when it initializes all security attributes, diagnostic attributes (if configured) , etc..
Perform server start and then check if it gets created or not.
## rank answer if it is helpful ##
Thanks,

Error message deploying a composite in SOA Suite 11g

Hello,
We are attempting to deploy a composite to SOA Suite 11g (11.1.1.3). We're getting an 'Unable to register service' error message. When I inspect the log files I see the following entry as the first error:
Failed to retrieve policy[[
oracle.wsm.policyaccess.PolicyAccessException: WSM-06146 : Error deleting the attachment entries.
Anybody have any experience with this error? The error message reference has the following listed:
WSM-06146: Error deleting the attachment entries.
Cause: Failure occurred while deleting the attachment entries.
Action: Ensure that a valid list of policy subjects for deactivated lifecycle type is passed

I don't know how to "ensure that a valid list of policy subjects for deactivated lifecycle type is passed". Please help!!!!
Thanks,

This is what we have done :
1.Created the JDBC data source & connection pool as below :
data source name : B2BAQ , JNDI name : jdbc/B2BAQ
Connection Pool :
URL : taken from the tns entries of the instance
Driver Class Name : oracle.jdbc.OracleDriver
Tested this connection ..it works fine from the Admin Console
2.Then go to Deployments --> AqAdapter -> Configuration tab --> Outbound Connection Pool Group -->
Create a new connection pool instance -- General tab
connection interface factory : javax.resource.cci.ConnectionFactory
JNDI Name : eis/AQ/B2BAQ
Then in Properties tab : Enter the Data Source Name : jdbc/B2BAQ
Then we try to Start the AqAdapter from the Admin Console..it goes into Prepared status.
The error message which comes is mentioned above.
Is there any way we could resolve this ..that would be very helpful
Regards

OracleBAMAdapter Configuration problem in SOA suite 11g

Hi,
In Oracle SOA suite 11g(11.1.1.2.0), OracleBAMAdapter configuration using WebLogic server console is resulting in the following error
* An error occurred during activation of changes, please see the log for details.
* [J2EE:160149]Error while processing library references. Unresolved application library references, defined in weblogic-application.xml: [Extension-Name: oracle.soa.workflow.wc, exact-match: false].
Steps used for configuration:
1) Modify adapter configuration using navigation:: Deployments -> OracleBAMAdapter -> Configuration -> Outbound Connection Pools -> oracle.bam.adapter.adc.RMIConnectionFactory -> eis/bam/rmi
2) Specified connection properties with BAM server port details
HostName localhost
InstanceName ADCServer1

Could you please help resolving this issue?

I do not think that would qualify as a solution :-). I was negligient in deploying Work Flow Application, and was not deselecting the checkbox in 11.1.1.2.0 JDeveloper, which reads out like "Deploy to all the servers". Thus it was trying to deploy it to BAM server as well as the Admin Server. I had to deselect it. It's pretty mundane thing that I was missing.
Warm regards.

Problem with DB JCA adapter in Soa suite 11g composite appl

i am testing a simple credit card validation composite with Oracle SOA suite 11g11.1.1.4.0, Jdevloper 11.1.1.3.0 and oracle universal XE DB. I am having an exception given below. I have checked that data source is properly configured and appearing at the right place in JNDI tree. Suggestion like 1) the Resource Adapters RAR file has not been deployed successfully to the WebLogic Application server or 2) the '<jndi-name>' element in weblogic-ra.xml has not been set to eis/DB/DBconnection. In the last case you will have to add a new WebLogic JCA connection factory (deploy a RAR) has also been tried result is same

Performance tuning of BPEL processes in SOA Suite 11g

Hi,
We are working with a customer for performance tuning of SOA Suite 11g, one of the areas is to tune the BPEL processes. I am new to this and started out with stress testing Hello World process using SOAPUI tool. I would like help with the below topics -
1. How do I interpret the statistics collected during stress testing? Do we have any benchmark set that can indicate that the performance is ok.
2. Do we need to run stress tests for every BPEL process deployed?
2. Is there any performance tuning strategy documentation available? Or can anybody share his/her experiences to guide me?
Thanks in advance!
Sritama

1. How do I interpret the statistics collected during stress testing? Do we have any benchmark set that can indicate that the performance is ok.
You need
pay attention to:
java heap usage vs java heap capacity
java eden usage vs java eden capacity
JDBC pool initial connections vs JDBC pool capacity connections
if you are using linux: top
if you are using aix: topas
2. Do we need to run stress tests for every BPEL process deployed?
yes, you need test each BPEL. You can use "Jmeter" tool.
Download Jmeter from here: Apache JMeter - Apache JMeter&trade;
Other tools:
jstat
jstack
jps -v
Enterprise Manager
WebLogic Console
VisualVM
JRockit Mission Control
3. Is there any performance tuning strategy documentation available? Or can anybody share his/her experiences to guide me?
I recommend "Oracle SOA Suite 11g Performance Tuning Cookbook" http://www.amazon.com/Oracle-Suite-Performance-Tuning-Cookbook/dp/1849688842/ref=sr_1_1?ie=UTF8&qid=1378482031&sr=8-1&keywords=oracle+soa+suite+11g+performance+tuning+cookbook

I just got the same error on deployment and realized i was going through a proxy server, who was responding with a http 503 code to deployment request from JDeveloper. Just check your proxy settings under Tools->Preferences->Web Browser and proxy and add an exception if needed.
I also had to restart JDeveloper (a bug?) after adding the exception to correct the issue.
regards,

Error while starting the AqAdapter in SOA Suite 11g Admin Console

facing an issue with the AqAdapter(Resource Adapter) in Soa Suite 11g Admin Console.
we go to Deployments --> Select Aq Adapter --> Currently it shows the status as Prepared
Now we try to Start it again --> it comes back with the error message mentioned below
weblogic.application.ModuleException: weblogic.connector.exception.RAException:
Jndi Name is null or empty. Errors were encountered while performing this operation.
source path on the admin server is mentioned here for this AqAdapter:
/opt101/app/oracle/SOAD/SOA11gR1/fmw/Oracle_SOA1/soa/connectors/AqAdapter.rar
deployment plan :
/opt101/app/oracle/SOAD/SOA11gR1/fmw/Oracle_SOA1/soa/connectors/was/Plan. xml
We check in the Configuration tab --> Outbound Connection Pools -->
here it shows the Group as javax.resource.cci.ConnectionFactory and under it we have setup
2 connection pool instances with JNDI names as : eis/AQ/aqSample & eis/aq/B2BAQ
Could someone please help here as to what could be the reason why this error is coming and
how we could resolve this.
With Regards & thanks

This is what we have done :
1.Created the JDBC data source & connection pool as below :
data source name : B2BAQ , JNDI name : jdbc/B2BAQ
Connection Pool :
URL : taken from the tns entries of the instance
Driver Class Name : oracle.jdbc.OracleDriver
Tested this connection ..it works fine from the Admin Console
2.Then go to Deployments --> AqAdapter -> Configuration tab --> Outbound Connection Pool Group -->
Create a new connection pool instance -- General tab
connection interface factory : javax.resource.cci.ConnectionFactory
JNDI Name : eis/AQ/B2BAQ
Then in Properties tab : Enter the Data Source Name : jdbc/B2BAQ
Then we try to Start the AqAdapter from the Admin Console..it goes into Prepared status.
The error message which comes is mentioned above.
Is there any way we could resolve this ..that would be very helpful

Query regarding integrating sun MQ with Oracle SOA suite 11g

Hi,
I am new to SOA suite 11g.I have a requirement of connecting to Sun MQ 4.4 queue from Oracle SOA suite 11g.Right now, I have found a work around using java embedding by connecting to the queue from java code directly.Can I use the JMS adapter for this purpose? If yes what are the options of doing that.I saw there is an option of third party queue in the JMS adapter configuration wizard but could not get it to work.Any help is appreciated.
Thanks in advance

I think we can exchange only data types, i dont see any data type which can hold the object types.
If you find anything better let us know.
Constructing string xml and converting to xml is best option i can think of.
Thanks,
Vijay

SOA Suite 11g Clustering error/oracle bug ?

Hi, i got several experiment to implement soa suite 11g clustering, in my company.. at this moment we still use development mode in our application server. now i'm trying to get into production and also i want cluster the server.. here is the chronology what i do.
i got 3 server :
my plan is
server #1 become an proxy server, let say the name is soa_proxy
server #2 become an cluster node, let say the name is soa_server1
server #3 become an cluster node, let say the name is soa_server2
so i start install & configure it (applications is running under Windows Server 2003)
1.*soa_proxy*
- Installing WebLogic server
- Installing SOA
- Create Repository with RCU (oracle 10g database)
2.*soa_server1*
- Installing WebLogic server
- Installing SOA
3.*soa_server2*
- Installing WebLogic server
- Installing SOA
after installation finished, then i create domain in soa_proxy server let say it name 'MyDomain', then i assign the soa_server1 and soa_server2 in cluster node named 'MyCluster', also i assign the soa_proxy server as a HTTP Proxy Server.. i'm following the instructions just like this link Link: [http://download.oracle.com/docs/cd/E12839_01/doc.1111/e13925/config_screens.htm#CJAEABGD]
all the installation seems good, but when i try to deploy my composite application into the proxy server 'soa_proxy' with JDev, i got error like this
Image: !http://img9.imageshack.us/img9/2122/error2z.jpg!
and when i go to Http://hostname:7001/em
i just see my composite deployed only in 'soa_server2'.
UPDATE : well, now the error was gone when deploying. but we still got little odd result,
when i deploy with jdev, it still fine, until i go to the enterprise manager. yess still.. my composite only deplyed in 'soa_server1'. i got some reference that we can copy the domain directory in soa_proxy and then paste into the server that not yet been deployed before. its seems oke..
i've been thinking, how if i got 10 node of cluster? 50 node of cluster ? should i copy the directory just like that ?? is there another charmed way to do it???
can somebody help me with this simple case?
regards
Wildan

=======
here is my last trial to deploy the cluster environment, then i just got the same issues, our team here think thats the issues causing by oracle bug in code behind. for reminder what i do last experiment
1. we deploy/configure the domain (admin console,cluster node) then starting up all the services smoothly without no issues & as we saw in the console monitor we can see the cluster is syncronizing.
2. then we create simple composite.
3. we try to deploy the composite to the cluster domain, and what we got is the composite only deployed in one cluster node.
let me describe to clear it,
* first trial, when we deploy the composite, here is what we got in em console
*[-] SoaInfra (SoaServer1)*
[+] CompositeLabTest
*[-] SoaInfra (SoaServer2)*
in JDev we also saw this message (the project CompositeLabTest Deploy Process is skipped), some kind like that
* second time trial, we try to shut the SoaServer2 down, then restart it, what we got in em console
*[-] SoaInfra (SoaServer1)*
[+] CompositeLabTest
*[-] SoaInfra (SoaServer2)*
[+] CompositeLabTest
. so until today my soa suite 11g clustering experience is never going good practice.. any of you may had experience with clustering too, how that can be done? please respon...
thanks
regards

Hi there.
Me too I have a similar problem with cluster deployment.
I have two different domains in two different phisical machine on the same LAN.
These domains are equals and the sole difference is regarding the IP configuration:
domain 1
machine 172.0.0.1
soaadmin 172.0.0.1
soa1 172.0.0.2
soa1 172.0.0.3
domain 2
machine 172.0.1.1
soaadmin 172.0.1.1
soa1 172.0.1.2
soa1 172.0.1.3
When I try to deploy a new composite from the EM this fails (it remains in waiting for a response like the followed)
<Jun 18, 2010 10:42:00 AM CEST> <Warning> <org.apache.myfaces.trinidadinternal.context.RequestContextImpl> <BEA-000000> <Could not find partial trigger idArchiveFileBrowserDialog from RichInputText[UIXEditableFacesBeanImpl, id=idArchiveLoc]>
Processing sar=/tmp/dir2448127768139530528tmp/sca_SOAComposite1_rev1.0.jar
Adding sar file - /tmp/dir2448127768139530528tmp/sca_SOAComposite1_rev1.0.jar
Creating HTTP connection to host:172.0.0.2, port:10002
What I checked:
In multicast configuration soa1 (domain1) sent the request to all soa servers in the LAN (even in that one that aren't configurated in his domain)
In unicast configuration soa1 (domain1) sent the request only to the soa2 (domain1) server but it remain in waiting for a response for all the time.
What it is strange is that if I stop the domain2 the request can be performed and my composite is deployed in both the servers.
Any idea about this strange behaviour?
N.B.
I'm not using Coherence.

Oracle SOA Suite 11g vs jdevstudio11.11

In reviewing the SOA Order Booking Quikstart Guide it requires that you download and configure Oracle SOA Suite. Prior to starting this Guide, I had already downloaded the Oracle SOA Suite 11g Technology Preview which included two downloads (JDeveloper and the update to the design and runtime). I followed the install instructions from the same site.
1) Having completed these two downloads and installs do I still need to install and configure the Oracle SOA Suite to run the SOA Order Quickstart Guide?
2) My understanding was that the Oracle SOA Suite 11g Technology Preview included the Oracle SOA Suite, is this correct? If not correct, do I need to also install the Oracle SOA Suite (my downloaded version is soa_windows_x86_101310_disk1.zip)?
3) When configuring the SOA Suite, per the guide, it states that I should go to http://loalhost:8888 but I do not get a connection. If I still need to install the Oracle Suite then I expect that this will solve this issue (per questions above) but if it already is isntalled with the SOA Suite 11g Technology Preview then I confused as to how to get this location to show up? I can get the SOA Console to show up but I don't know if this is the same?

The SOA Orderbooking Quickstart is for SOA Suite 10.1.3.x. If you want to run this sample, you do have to install SOA Suite 10.1.3.x. This is the current released version of SOA Suite.
The Technology Preview 3 is SOA Suite 11g. This version is in a pre-beta/preview status right now. It has the SOA Suite with the JDeveloper. This version has its own tutorials/samples.
In reply to your specific questions:
1) the two downloads for the TP3 do not apply to the 10.1.3.1 SOA Orderbooking Quickstart.
2) The 11g TP3 does include the 11g SOA Suite and you do not need to install the 10.1.3.1 zip to run the preview.
3) When you run the SOA Suite 10.1.3.1, the default port is 8888. When you run the 11g SOA Suite inside JDev, the default port is 8988.

Best approach taking soa suite 11g on internet

Currently our soa suite environment 11.1.1.4 is operating within intranet only. Now we need to publish our services on the internet. I am looking for the security mechanism that I should apply in order to make the services secure. I may even like to verify that the request invoking service A is only coming from specified context.
I have come across the page http://download.oracle.com/docs/cd/E21764_01/secure.htm. And this page is giving lot of information.
Can you please give me an idea what might be the best practices in this regard ? What options I have that can be implemented while taking soa suite 11g on the internet.

Now we need to publish our services on the internet. I am looking for the security mechanism that I should apply in order to make the services secure. I may even like to verify that the request invoking service A is only coming from specified context.One approach we followed at a customer :
- SOA was installed within internal firewall zone
- A F5 BigIP Load Balancer was setup in DMZ. This load balancer terminated one way SSL connections coming from service consumers over internet. The load balancer forwaded the request to a pool of apache of web servers within DMZ
- The Apache web servers had a redirection rule which forwarded the request to the soa server ports within the internal firwall zone. The internal firewall was opened to allow connections between apache web servers and soa server ports.
- WS Security Username token/plain text password was used for message level security at the soa services layer.
Some alterations you can do :
1. enforce 2 way ssl and make load balancer to validate the CN of the client certificate. This can make sure only authorized clients are to make calls to the service
2. OR setup some sort of IP filtering at DMZ firewall i.e. allow traffic only from authorized clients IP addresses to the load balancers virtual address for this specific service.

SOA Suite 11g Coding Best Practice Document

Hello,
I am looking for coding best practice dosument for SOA suite 11g. I have seen one document for "soa_best_practices_1013x_drop3" but this was for SOA 10g. I could not find any such document for SOA 11g. Please let me know if some one has document for best practice, coding standard, naming convention for BPEL,OSB,B2B etc.

Prashant

SOA Suite 11g HA install and EDNDataSource problem

Hi all,
We have installed and configured Oracle SOA Suite 11g (11.1.1.5) cluster per the instructions in the Enterprise Deployment Guide and Anthony Reynold's blog (http://blogs.oracle.com/reynolds/entry/installing_an_11g_soa_cluster). We are encountering constant XA and DBLocker related errors with the EDNDataSource:
<Dec 1, 2011 2:35:29 AM MST> <Error> <JDBC> <BEA-001112> <Test "SELECT 1 FROM DUAL" set up for pool "EDNDataSource" failed with exception: "oracle.jdbc.xa.OracleXAException".>

These errors occur every couple of seconds on both SOA hosts. Additionally, we see errors on one of the hosts, complaining about EDNDataSource not being clusterable:
<Dec 1, 2011 2:35:29 AM MST> <Error> <Cluster> <BEA-000123> <Conflict start: You tried to bind an object under the name weblogic.transaction.resources.SOA1.EDNDataSource_soa_domain in the JNDI tree.

Such objects can only be deployed from one server.>
We have ensured that the database (we are using a single Oracle 11g database instance, not RAC) has XA support enabled. Beyond this, we haven't found any leads on this forum nor the Oracle support site (we have opened an SR with Oracle). I've seen a couple of other threads related to this issue over the last year (e.g., Re: JTA - XA Rources - Rollbacks reason and What is the purpose of EDNDataSource in SOA 11g? but no resolution was ever posted.
Does anyone have any suggestions of where to being looking to troubleshoot this issue? Any help would be most appreciated!
Thanks,

How are you starting the server? Using start script - ./startManagedWebLogic.sh soa_server1? Make sure that classpath is getting set properly.Yes, after using the script to start the admin server.
How do I make sure the classpath is getting set properly? Seems to be the actual problem, but from the logs when the server starts up the command seems correct from what I can see. If I knew which jars contained the classes it needed I could try and look for them in the start command.
11g is not certified on Ubuntu. Please refer below link for certification matrix -I actually wished Oracle could certify the installers for Mac OSX (just for development), but I guess I could try and get things up on Redhat instead. :P
Thanks for the input.

How to configure something similar to optSoapShortcut in SOA Suite 11g

Hi,
We are migrating processes in BPEL 10g to composites in SOA Suite 11g (11.1.1.5). In one of these processes we are extracting the ws-addressing elements replyTo and MessageID from the SOAP header from the calling process and saving these values into a database. They are later used to be able to reply back to the calling process. In 10g this was no problem but in 11g calls between processes are automatically optimized, meaning that they are not communicating using SOAP. Hence, it seems like we can't get the soap headers the normal way.
According to the Administration Guide for SOA Suite 11.1.1.5 the optSoapShortcut property has been removed which could be used in 10g to specify if the calls should be optimized or not. Is there any other way to configure this in SOA Suite 11g?
If not, is there any way to instead extract these elements from some BPEL API or similar?
Thanks!
Best wishes
Kerstin

For release 11g, SOAP optimization is automatically configured. Therefore, if you upgrade your projects from 10g to 11g and are using the optimized shortcut approach in existing applications, note that optimized calls are activated only when the hostname value (as referred to in the WSDL URL in the composite.xml file) matches the Server URL value. Either set both values to the hostname (for example, myhost) or to the full domain name (for example, myhost.domain.com). If these values do not match, a regular SOAP call is performed instead of an optimized local call.
You can still control this using oracle.webservices.local.optimization property.
http://docs.oracle.com/cd/E15586_01/web.1111/b32511/configuring.htm#WSSEC3522
Refer to "Controlling When Local Optimization is Used"
