Component Metrics are Unavailable for the SOA Composite in EM console - Oracle SOA Suite 11g

Component Metrics are Unavailable for the SOA Composite in EM console - Oracle SOA Suite 11g

I was facing a strange issue with Oracle SOA Suite EM console. Whenever opening the SOA Composite the component metrics are not getting displayed and it is shown as Unavailable.


The issue is only happening in Development environment but it is working fine in all the other environments.
I could not able to find any exception related to this issue in any of the log files.

Unfortunately the Component metrics are getting displayed after refreshing the SOA Composite(from right corner of EM page as shown in the above diagram) from EM console




Deployment plan file to replace the Binding Adapter Properties/Attributes – Oracle SOA Suite

Deployment plan file to replace the Binding Adapter Properties/Attributes – Oracle SOA Suite

The deployment plan file will help us to dynamically replace the Oracle SOA Suite Composite properties.

This post explain the steps to replace the Properties/Attributes of the Direct Binding Adapter in Composite.xml. The same steps can be used to replace the Properties/Attributes of all the Binding Adapters.

Generate the Plan file:

The plan file can be generated through JDeveloper or through ANT script.

Generating Plan file through JDeveloper:

Right Click on Composite.xml and click on generate config Plan.


Change the generated plan file contents accordingly to replace the properties and attributes of the composites. 

Add the required attributes to the corresponding Binding and change the values accordingly(by default the attributes will not be added to the corresponding binding in the plan file) and also change the value of required properties accordingly.

The selected WSDL contain a direct binding but seems to be of the wrong type - Oracle SOA Suite

The selected WSDL contain a direct binding but seems to be of the wrong type - Oracle SOA Suite

You will be receiving the message "The selected WSDL contain a direct binding but seems to be of the wrong type. Looking for Oracle Service Bus type.Please check your WSDL selection" while trying to create the direct binding to invoke the OSB service.


This message says the OSB proxy service is not configured with SB transport.
Configure the OSB Proxy service with the SB transport to invoke the same from SOA composite through Direct Binding.

When looking up the OSB service from JDeveloper SOA Resource Browser, the Proxy will be shown as direct for SB transport services.

WLST script to Enable/Disable the debug flags in Weblogic Server

WLST script to Enable/Disable the debug flags in Weblogic Server


This tutorial explains the approach to enable/disable the debug flags in Weblogic Server.

The Debugging flags will help us to enable/disable the debugging for different modules in weblogic.

The flags can be enabled/disabled in different ways

Admin Console


Access admin console — http://localhost:7001/console
Navigate to Environment →Servers → <<Server>> → Debug



Select the required flags and click on Enable/Disable.



WLST Script


The below WLST script enable the Debug Flag ‘DebugSSL’ for configured servers

EnableORDisableDFlags.properties

serverflagconfigs=AdminServer=DebugSSL:false,MS1=DebugSSL:true


EnableORDisableDFlags.py
import re
from java.io import FileInputStreamdef EnableORDisableDFlags(): edit()
 startEdit()
 propInputStream = FileInputStream('EnableORDisableDFlags.properties')
 configProps = Properties()
 configProps.load(propInputStream)  
 
 serverflagconfigs = re.split(",",configProps.get("serverflagconfigs"))
 print serverflagconfigs
 
 for serverConfig in serverflagconfigs: 
 
   serverName=re.split("=",serverConfig)[0]
   config=re.split("=",serverConfig)[1]
   print config
   cd('/Servers/'+serverName+'/ServerDebug/'+serverName)
   flagName=re.split(":",config)[0]
   flagValue=re.split(":",config)[1]
   set(flagName,flagValue)
   print 'Modified the DFlag for '+serverName+' '+ flagName+':'+flagValue
 save()
 activate()  
   
  
def main():
    adminURL='t3://localhost:7001'
    adminUserName='weblogic'
    adminPassword='weblogic1'
    connect(adminUserName, adminPassword, adminURL)
    EnableORDisableDFlags();
    print 'Successfully Modified the DFlags'
    disconnect()
main()


Script -
https://github.com/techforum-repo/youttubedata/tree/master/scripts/wlst/EnableORDisableDFlags

Before executing the script, change the configurations as required.

Execute the script — <<Oracle_Home>>\oracle_common\common\bin\wlst.cmd EnableORDisableDFlags.py




Now the DebugFlag is Enabled/Disabled based on the configurations



JVM start arguments


The debug flags can be enabled/disabled through server start up arguments

Add the flags with -D to the server start up arguments through console Environment →Servers →<<Server>> →Server Start

-Dweblogic.debug.DebugSSL=false



Other option is add the debug flags to the start up file startWebLogic.cmd/startWebLogic.sh or startManagedWebLogic.cmd/startManagedWebLogic.sh based on which file is used to start the server.

e.g.

JAVA_OPTIONS=”${JAVA_OPTIONS} -Dweblogic.debug.DebugSSL=true

The changes will take effect after restarting the server

SOA-INFRA Application is in unknown Type - Oracle SOA Suite 11g

SOA-INFRA Application is in unknown Type - Oracle SOA Suite 11g:

I was facing a strange issue,the Type of the soa-infra application was unknown but the state and the health of the application is looking fine(Active and OK) in admin console.
Because of this the SOA node is not displayed in the em console.




Tried restarting the server without any luck and also updated(redeployed) the soa-infra application but still the type of the application is unknown.

I could not able to find any exception related to this issue in the log files and also there is no issue related to the database schema's.

Steps to resolve the issue

Delete the soa-infra application from the admin console deployments.
Install the soa-infra application(soa-infra-wls.ear) from the location SOA_HOME\soa\applications as Enterprise Application.

WLST script to enable Backup/Archive configurations in weblogic server

WLST script to enable Backup/Archive configurations in weblogic server


By enabling the backup/archiving in Weblogic, the administration Server can automatically backups the domain configuration (the entire domain-name/config directory) during the server boot to DOMAIN_HOME\config-original.jar and config-booted.jar.

Also multiple versions of the domain config will be archived by the Administration Server, each time the domain configuration is modified into the DOMAIN_CONFIG\configArchive folder.

The configuration archives can be used for system restoration in cases where accidental configuration changes need to be reversed.

This tutorial explains how to use WLST script to enable backup/archive configurations.


WLST Script


The below WLST script will help us to enable the backup/archive configurations

EnableArchiving.py

adminURL='t3://localhost:7001'
adminUserName='weblogic'
adminPassword='weblogic1'
connect(adminUserName, adminPassword, adminURL)
domainRuntime()
edit()
startEdit()
cmo.setConfigBackupEnabled(true)
cmo.setArchiveConfigurationCount(5)
save()
activate()



Script
https://github.com/techforum-repo/youttubedata/blob/master/scripts/wlst/EnableArchiving.py

Execute the script

<<Oracle_Home>>\oracle_common\common\bin\wlst.cmd EnableArchiving.py



Verify the configuration


To verify the configuration- Login to admin console →Click on Domain in the left panel →Expand the Advanced in General Configuration section



When the Admin Server starts up it automatically makes a backup of DOMAIN_HOME/config directory and stores it in DOMAIN_HOME/config-original.jar(original configuration file while restarting the server) and once the start up completed(booted) successfully it makes a backup of DOMAIN_HOME/config directory and stores it in DOMAIN_HOME/config-booted.jar(the config file on which the server is booted successfully) .

Most of the cases both of the file contents will be same. If the server fails to boot successfully the config-booted.jar will not be generated and the old config-booted.jar file will be left as it is.



Also whenever the domain configuration is modified, the admin server archive the previous configurations to the DOMAN_HOME\configArchive folder.The files use the naming convention as config-number.jar, where number is the sequential number of the archive.After it reaches the maximum number of archive files specified in the configuration(ArchiveConfigurationCount — 5), older archive files will be discarded



Recover the configurations


Follow the below steps to recover the configurations from archive

Stop the servers

Rename the current <<DOMAIN-HOME>>/config folder to config-bkp

Create a folder with name config under <<DOMAIN-HOME>>

cd to <<DOMAIN-HOME>>/configArchive in a command prompt

Execute the below command(change the archive file name as required)

tar -xf config-1.jar -C <<DOMAIN-HOME>>\config



Start the server — now the configurations are restored from the archive.

Transforming the REST XML message to SOAP message - OSB

Transforming the REST XML message to SOAP message - OSB

This post will explain how to Transform the REST XML message to SOAP message in OSB

While receiving the response from REST interface  with the content type as application\xml, the input XML will be plain without the target namespace specified.
But if you are invoking the BPEL with this message the BPEL cant perform any xpath operations on this message without target namespace.The target namespace should be added to the message.

The XSLT can be used to add the name space to the XML message but before performing this operation the SOAP envelope of the body variable should be removed
After removing the namespace the XML should be assigned to the body variable to send to target system.

Follow the below steps to achieve the same:

Remove SOAP Envelope:

The below XSLT will help as to remove the namespace from the XML.

Create a XSLT resource from SB console.
Add a Assign activity with the XSLT resource
Assign the output to a temp variable - var1.

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match="@* | node()">
        <xsl:copy>
          <xsl:apply-templates select="@* | node()" />
        </xsl:copy>
      </xsl:template>

      <xsl:template match="soapenv:*">
        <xsl:apply-templates select="@* | node()" />
  </xsl:template>
</xsl:stylesheet>




Transforming the SOAP message to REST XML message- OSB

Transforming the SOAP message to REST XML message- OSB

While invoking the REST interface from OSB with the content type defined as application\xml, the target system will expect the simple XML message without the target namespace specified.

The XSLT can be used to remove the name space from SOAP message but before performing this operation the SOAP envelope of the body variable should be removed
After removing the namespace the XML should be assigned to the body variable to send to target system.

Follow the below steps to achieve the same:

Remove SOAP Envelope:

The below XSLT will help as to remove the namespace from the XML.

Create a XSLT resource from SB console.
Add a Assign activity with the XSLT resource
Assign the output to a temp variable - var1.

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match="@* | node()">
        <xsl:copy>
          <xsl:apply-templates select="@* | node()" />
        </xsl:copy>
      </xsl:template>

      <xsl:template match="soapenv:*">
        <xsl:apply-templates select="@* | node()" />
  </xsl:template>
</xsl:stylesheet>

Removing Namespace:

The below XSLT will help as to add the target namespace to the XML.

Create a XSLT resource from SB console.
Add a Assign activity with the XSLT resouce  to remove the namespace from the variable var1
Assign the ouput to a temp variable - var2

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match="*">
        <xsl:element name="{local-name()}">
            <xsl:apply-templates select="@* | node()" />
        </xsl:element>
    </xsl:template>
    <xsl:template match="@*">
        <xsl:attribute name="{local-name()}">
            <xsl:value-of select="." />
        </xsl:attribute>
    </xsl:template>
    <xsl:template match="text() | comment() | processing-instruction()">
        <xsl:copy />
    </xsl:template>
</xsl:stylesheet>

Assign the content of var2 to body:

Add replace activity to replace the node contents of body with var2




Unable to post the message to MQ through MQ adapter - Oracle SOA Suite

Unable to post the message to MQ through MQ adapter - Oracle SOA Suite

Sometimes we will be getting the below exception while posting the message to MQ  through MQ adapter in Oracle SOA Suite.

"Exception occured when binding was invoked. Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'Enqueue' failed due to: A webSphere MQ Error occurrred[while putting the message]. A webSphere MQ Error occurrred[while putting the message]. A webSphere MQ Error occurrred while putting the message in Queue: "EAI_ORD_RPLY_Q ". Please make sure that the Queue is Put enabled, not full, message do not exceeds maximum message length and QueueManger is up and running. ". The invoked JCA adapter raised a resource exception. Please examine the above error message carefully to determine a resolution."


Mainly this exception can occur if there is any issue with the MQ Adapter configuration or issue with the MQ server components.

The following steps can be followed to identify the issue.

MQ Adapter perspective:

Verify the MQSeriesAdapter health and state is fine


Verify the connection factory used in the Adapter is configured in weblogic server
