[WLS 12.2.1.0.0] Managed servers going to FORCE_SHUTTING_DOWN state when resumed from ADMIN state.

Hello Viewer,

I have noticed one of the weird behavior in wls 12.2.1.0.0 version , where in when we start the server and in case any of the datasource do not come up because of associated database issue(database down or any other related issue). In that case server will stuck to Admin state which is normal behavior but when we will try to resume it from console it will again go to shutdown state.

Workaround: 

Reduce the initial connection capacity for datasource to ZERO.

Thanks a lot for your patience!!!

Failed to initialize the application "SB_JMS_Proxy_N7de264e1.N2efb99d.2.1553951a327.N7ffe" due to error weblogic.management.DeploymentException: Exception occured while downloading files

Hello Viewer,

Today i faced one issue while bringing up the OSB servers.Servers were not coming up. After reaching to Admin state it again went to force shutting down mode.

After seeing the logs i got the below error:

 <Error> <Deployer> <BEA-149205> <Failed to initialize the application "SB_JMS_Proxy_N7de264e1.N2efb99d.2.1553951a327.N7ffe" due to error weblogic.management.DeploymentException: Exception occured while downloading files

Caused By: java.io.IOException: [DeploymentService:290066]Error occurred while downloading files from Administration Server for deployment request "0". Underlying error is: "null"


Solution: Login to Admin console and goto deployments, search the ear for which you are facing the error, it should be in failed state.
It will not allow you to untarget this ear.just delete it from deployments and try to restart the server. This time servers should come up.

Thanks a lot for your patience!!!

[WLS 12.2.1.0.0]Script to get the email notification in case current or pending messages on distributed queues are greater than zero on any of the JMS server.

Hello Viewer,

I wanted to get the notification in case current or pending messages on distributed queues are greater than zero on any of the JMS server.

One easy way for this is to create watches and Notification under WLDF. But since i am using weblogic version 12.2.1.0.0, it is not easy to create policy for this task as rule expression tab is not present in 12.2.1.0.0 when policy type is "collected metric".

So i thought of creating the script which can constantly monitor the set of queues and will send an email notification having html content with proper cosmetics :)

Below are the steps to be followed:

1) Create a file QueueReport.sh with below content:

----------------------------------------------------------------------------------------------------------

#!/bin/sh

# set up WL_HOME, the root directory of your WebLogic installation

WL_HOME="wl_home"

cd /MyLocation/QueueReport

rm QueueReport.txt

umask 027

   echo "CHECKING QUEUE STATUS " > finalStatus3.out

    while read LINE; do

      date >> QueueReport.txt

      queue=$(echo "$LINE" | awk -F, '{ print $1 }');

    sh ${WL_HOME}/common/bin/wlst.sh /MyLocation/QueueReport/QueueReport.py $queue >> QueueReport.txt

    done < QueueList.txt

cat QueueReport.txt | grep "queue/topic" >> finalStatus3.out

grep -v "is 0 and 0" finalStatus3.out > temp.txt

mv temp.txt finalStatus3.out

echo "CHECKED QUEUE STATUS " >> finalStatus3.out

----------------------------------------------------------------------------------------------------------

2) Create a file QueueReport.py with below content:

Note: I am assuming there are two Managed server and two JMS server targeted to each managed server respectively.

 Change the below values according to your ennvironment.

jms_module name: JMS_TST_MODULE

jms server name :  JMS_TST_SERVER1,  JMS_TST_SERVER2

managed server name:  SOA_MS1,  SOA_MS2

-----------------------------------------------------------------------------------------------------------

import ConfigParser

def connectToServer():

        USERNAME = 'username'

        PASSWORD = 'password'

        URL='t3://Adminhost:Adminport'

        #Connect to the Administration Server

        print 'starting the script ....'

        connect(USERNAME,PASSWORD,URL)

def disconnectFromServer():

    print "Disconnecting from the Admin Server"

    disconnect()

    print "Exiting from the Admin Server"

    exit()

    print "Mission Accomplished"

def readConfigurationFile(myDestinationName):

    try:

          cd('ServerRuntimes/SOA_MS1/JMSRuntime/SOA_MS1.jms/JMSServers/JMS_TST_SERVER1/Destinations/JMS_TST_MODULE!JMS_TST_SERVER1@'+myDestinationName)

        current1=str(cmo.getMessagesCurrentCount());

        pending1=str(cmo.getMessagesPendingCount());

      cd('ServerRuntimes/SOA_MS2/JMSRuntime/SOA_MS2.jms/JMSServers/JMS_TST_SERVER2/Destinations/JMS_TST_MODULE!JMS_TST_SERVER2@'+myDestinationName)

        current2=str(cmo.getMessagesCurrentCount());

        pending2=str(cmo.getMessagesPendingCount());

        totalcurrent = int(current1) + int(current2)

        totalpending = int(pending1) + int(pending2)

        print 'The number of current/pending  messages on JMSServer in the queue/topic '+myDestinationName+' is '+str(totalcurrent)+' and '+str(totalpending)

    except :

        print 'Unable to find admin server...'

        exit()

    print 'Command executed successfully'

[OSB 12c] java.lang.RuntimeException: java.lang.RuntimeException: java.lang.ClassNotFoundException: com.bea.wli.sb.management.configuration.DelegatedSessionManagementMBean

Hello viewer,

I was trying to create the scripts for performing different operation on OSB like deployment , enabling/disabling of proxy, list out the deployed OSB service etc..

Although i have already created these scripts for 11g version of OSB but the jars which i used in shell script are not working in 12c.

In 12c below jar are not available: [snippet from .sh file]

--------------------------------------------------------------------------------------------------------

export CLASSPATH=$CLASSPATH:$OSB_HOME/Oracle_OSB/lib/sb-kernel-api.jar

export CLASSPATH=$CLASSPATH:$OSB_HOME/modules/com.bea.common.configfwk_1.2.1.0.jar

export CLASSPATH=$CLASSPATH:$OSB_HOME/Oracle_OSB/lib/alsb.jar

export CLASSPATH=$CLASSPATH:$OSB_HOME/Oracle_OSB/lib/sb-kernel-impl.jar

---------------------------------------------------------------------------------------------------------

when i tried to run the same script in 12c it was giving the error:

java.lang.RuntimeException: java.lang.RuntimeException: java.lang.ClassNotFoundException: com.bea.wli.sb.management.configuration.DelegatedSessionManagementMBean

 Solution:

write below command in your shell script(.sh file)

a) MW_HOME="middleware home where osb is installed"
    export MW_HOME

b). $MW_HOME/osb/tools/configjar/setenv.sh

DON'T miss the dot(.) in above command

c) ${MW_HOME}/osb/tools/configjar/wlst.sh  ${DIR_EXECUTION}/proxytask.py

use wlst.sh from this location   ${MW_HOME}/osb/tools/configjar

Thanks a lot for your patience!!!

Script to create multiple workmanager in weblogic domain.

Hello Viewer,

I was asked to migrate the current weblogic resources to new weblogic domain as a part of upgrade project, among those weblogic resources there were around seventy workmanager with corresponding MaxThreadsConstraints.

I could manage to find the script on google for this task but only for single workmanager. So i tried to slightly tickle this script for managing this task of creating multiple workmanager with there corresponding MaxThreadsConstraints and MinThreadsConstraints in one go.

Below are steps to be followed.

1) Create a file with name createWorkManager.py with below content:

--------------------------------------------------------------------------------------------------------------

import sys

import os

import jarray

import dircache

from java.io import File

from java.io import FileInputStream

from java.lang import String

propInputStream = FileInputStream("details.properties")

configProps = Properties()

configProps.load(propInputStream)

domainName=configProps.get("domain.name")

adminURL=configProps.get("admin.url")

adminUserName=configProps.get("admin.userName")

adminPassword=configProps.get("admin.password")

totalWM_to_Create=configProps.get("total.WM")

#connection()

connect(adminUserName, adminPassword, adminURL)

edit()

startEdit()

print '======= Creating a WorkManager name as ======='

i=1

while (i <= int(totalWM_to_Create)) :

    try :

         cd('/')

         workManagerName=configProps.get("workManagerName."+ str(i))

         maxThreadConstraintName=configProps.get("maxThreadConstraintName."+ str(i))

         minThreadConstraintName=configProps.get("minThreadConstraintName."+ str(i))

         ServerName=configProps.get("ServerName."+ str(i))

         MaxThread=configProps.get("MaxThread."+ str(i))

         MinThread=configProps.get("MinThread."+ str(i))

         cd('edit:/SelfTuning/' + domainName + '/WorkManagers/')

         create(workManagerName,'WorkManagers')

         cd('edit:/SelfTuning/' + domainName + '/WorkManagers/' + workManagerName)

         cmo.addTarget(getMBean("/Clusters/"+ ServerName))

         save()

         print ' WorkManager Created...'

    

         print '======= Creating MaxThreadsConstraint ======='

         cd('edit:/SelfTuning/' + domainName + '/MaxThreadsConstraints/')

         try:

             create(maxThreadConstraintName,'MaxThreadsConstraints')

         except Exception:

             print 'Issue in Creating MaxThreads exiting'

         cd('edit:/SelfTuning/' + domainName + '/MaxThreadsConstraints/' + maxThreadConstraintName)

         cmo.addTarget(getMBean("/Clusters/"+ ServerName))

         set('Count',MaxThread)

         save()

    

         print '======= Creating MinThreadsConstraint ======='

         cd('edit:/SelfTuning/' + domainName + '/MinThreadsConstraints/')

         try:

             create(minThreadConstraintName,'MinThreadsConstraints')

         except Exception:

             print 'Issue In Creating MinThreads '

         cd('edit:/SelfTuning/' + domainName + '/MinThreadsConstraints/' + minThreadConstraintName)

         cmo.addTarget(getMBean("/Clusters/"+ ServerName))

         set('Count',MinThread)

         save()

    

         print '======= Assigning the MaxThreadConstraint to the WorkManager ======='

         cd('edit:/SelfTuning/' + domainName + '/WorkManagers/' + workManagerName)

         bean=getMBean('/SelfTuning/' + domainName + '/MaxThreadsConstraints/' + maxThreadConstraintName)

         cmo.setMaxThreadsConstraint(bean)

    

         print '======= Assigning the MinThreadConstraint to the WorkManager ======='

         cd('edit:/SelfTuning/' + domainName + '/WorkManagers/' + workManagerName)

         bean=getMBean('/SelfTuning/' + domainName + '/MinThreadsConstraints/' + minThreadConstraintName)

         cmo.setMinThreadsConstraint(bean)

    

         print '==> WorkManager Creation Finished ... Please Double Check from AdminConsole...'

    except:

        print '***** CANNOT CREATE Workmanager!!! Check If the Workmanager With the Name : ' , workManagerName ,' Alreday exists or NOT...'

        print ''

    i = i + 1
print '========================================='

save()
activate()

--------------------------------------------------------------------------------------------------------- 

2) create a file with name createWorkManager.sh with below content:

----------------------------------------------------------------------------------------------------------

#!/bin/sh

export LOGFILE="/Mylocation/createWM.log"

if [ -f $LOGFILE ]; then

  rm -f $LOGFILE

fi

rm -rf /Mylocation/createWM.log

WL_HOME="your weblogic_home"

export WL_HOME

cd /Mylocation/

sh ${WL_HOME}/common/bin/wlst.sh /Mylocation/createWorkManager.py >> /Mylocation/createWM.log

exit

-----------------------------------------------------------------------------------------------------------

Note: change wl_home and mylocation as per your environment and requirement. 

3) create a properties file with name "details.properties" which will have the details like below :

-----------------------------------------------------------------------------------------------------------

domain.name=DOMAIN_NAME

admin.url=t3://Adminhost:Adminport

admin.userName=username

admin.password=xxxxxxxxx

total.WM=2

ServerName.1=SOA_CLUSTER

MinThread.1=7

MaxThread.1=15

workManagerName.1=MyTestWorkManager1

maxThreadConstraintName.1=MyTestMaxThreadConstraint1

minThreadConstraintName.1=MyTestMinThreadConstraint1

ServerName.2=SOA_CLUSTER

MinThread.2=7

MaxThread.2=15

workManagerName.2=MyTestWorkManager2

maxThreadConstraintName.2=MyTestMaxThreadConstraint2

minThreadConstraintName.2=MyTestMinThreadConstraint2

---------------------------------------------------------------------------------------------------------------

Note:

a) total.WM = total number of workmanager you want to create.

b) Don't forget to add numeric suffix for every new entry.

4) Flow:

createWorkManager.sh ----> createWorkManager.py---------> details.properties

5) How to run :

a) Go to /Mylocation

cd /Mylocation/

b) execute the shell script:

sh createWorkManager.sh

Thanks a lot for your patience!!!

Email Notification from ORACLE MFT 12C(12.1.3.0.2)

Hello Viewer,

For an efficient support it is always a smart choice to make the work easier and productive.Oracle has provided new tool ORACLE MFT to manage the file transfers. But in case of any failed transfer , our system should be well equipped with the method which can give us an alert rather than keep on monitoring the console and wasting most of the time in sitting ideal like zombie.  

ORACLE MFT has a build in feature of email notification for different kind of events.In this blog i  will provide you the steps to enable notification for few of the events.

This is two step process:

1) configure the email driver configuration.

2) Enabling event , creating contact and associating this contact with event.

Step(1) 

             1) Goto EM console

             2) Expand User Messaging Service.

             3) Click on usermessagingdriver-email (mft_server1)> click on Email Driver properties from                    drop down list.

             4) click on create and provide the details:

                  essential field that you should know is :>

                  a) Outgoing Mail Server, Outgoing Mail Server port

                  b) Default sender Address

                  c) Outgoing Username and password(Make sure this user should be there in your security                        realm)

             5) After providing all the values click on OK  and logout. Login again and see the updated                      values should be there.

Steps(2) 

          

               1) Login to you MFT machine(node) on which you have installed it.

               2) run the ./wlst.sh

               3) connect to your MFT server using connect() wlst command and execute the below wlst                        commands.

              a)  connect('username','password',t3://Adminhost:MFTserverPORT)

              b)  updateEvent('RUNTIME_ERROR_EVENT', true)

              c)   createContact('Email', 'ABD@host.com') 

              d)   addContactToNotification('RUNTIME_ERROR_EVENT', 'Email',            'ABD@host.com') 

Note: Here i have given example taking one of the event there are many other as well.

1) RUNTIME_ERROR_EVENT

               This event tracks the errors occurred at runtime. For example:

                               • Any errors that occur during the message processing 

                               • Server start errors 

                               • System event failure errors

2) DEPLOY_ARTIFACT_EVENT

This event tracks the artifact deployment events.

etc...

Restart the managed server and replicate any error scenario in MFT transfers and check if you are receiving email on email id: ABD@host.com

Thanks a lot for your patience!!!

 [12.2.1.0.0] Failed to start the BAM Alert Engine

Hello Viewers,

I was trying to configure the BAM Alerts with Email Notification feature. I created the BAM alerts in BAM composer and configured the BAM properties and user messaging driver.


while deactivating the alert I was getting the pop up saying "unable to deactivate the alert" but actually it gets deactivate. same behavior when i was trying to activate it.
When i was trying to save the alert it is "showing unable to load the alert"

In logs i was getting the below error:

-------------------------------------------------------------------------------------------------------------------------------------------------------------
<Apr 3, 2016 1:54:44 AM EDT> <Warning> <oracle.beam.server> <BEA-000000> <BAM Alerts Engine Service failed to start. 
Exception: java.lang.StringIndexOutOfBoundsException: String index out of range: 4 
at java.lang.String.substring(String.java:1963) 
-------------------------------------------------------------------------------------------------------------------------------------------------------------

Applied all the mandatory patches for BAM and restarted the server after clearing tmp, cache and data folder but still got the same issue.

Solution :

1) Go to EM -> Navigate to Business Activity Monitoring -> BAMServer -> BAM Properties
2) Click on "More Advanced configuration
3) Search for ScheduledDataPurgeTimeForDataObject property, change its value from 1:0:0 to 01:00:00
4) Save your changes.
5) Restart the environment.

Thanks a lot for your patience!!!

Oracle Coherence GE 12.2.1.0.0 <D5> (thread=ReplicatedCache:SOAReplicatedCache, member=15): Member 13 joined Service SOAReplicatedCache with senior member 15> 

Hello Viewer,

I have 2 unix box on which  two TEST environment were built with SOA and OSB domain for each.

Taking reference of only SOA domain :

SOA_TEST1_DOMAIN:

Admin server(Machine1)

BAM server1(Machine1)

BAM server2(Machine2)

SOA_server1(Machine1)

SOA server2(Machine2)

SOA_CLUSTER: SOA_server1, SOA server2

BAM_CLUSTER: BAM server1,BAM server2

SOA_TEST2_DOMAIN:

Admin server(Machine1)

BAM server1(Machine1)

BAM server2(Machine2)

SOA_server1(Machine1)

SOA server2(Machine2)

SOA_CLUSTER: SOA_server1, SOA server2

BAM_CLUSTER: BAM server1,BAM server2

Note: cluster name in both the domain is same i.e SOA_CLUSTER and BAM_CLUSTER.

Issue:

===

--Whenever i was trying to deploy a service in TEST2 environment, I see errors in the TEST1 Env and the deployment hangs and/or timeouts with errors..

--When I shutdown TEST2 Env, than the Deployment goes through fine.

-- After bringing up the TEST2 environment again , already deployed composite becomes inaccessible in TEST1

Error in logs:

<Trace> <com.oracle.coherence> <soaXXXX.cos.XXXX.com> <soa_server1> <Logger@9215997 12.2.1.0.0> <<anonymous>> <> <a3379798-6804-442d-a3de-4a5576fc5975-00000004> <1458800884649> <[severity-value: 256] [rid: 0:6] [partition-id: 0] [partition-name: DOMAIN] > <BEA-000000> <[com.tangosol.coherence.component.util.logOutput.Jdk:log] 2016-03-24 02:28:04.649/212.173 Oracle Coherence GE 12.2.1.0.0 <D5> (thread=ReplicatedCache:SOAReplicatedCache, member=15): Member 13 joined Service SOAReplicatedCache with senior member 15>

After going through all the possible cause , we ended up on coherence factor.Actually whenever i was trying to bring up the servers in TEST2 environment , servers were getting registered as a member of already running SOA_CLUSTER i.e cluster of TEST1.

we tried to add the coherence parameter with different port in both the domains but still issue was occurring.

In 12c , while creating a domain we get a wizard to configure coherence cluster, by default weblogic provides us the coherence cluster named as defaultCoherenceCluster with all the Weblogic cluster(SOA_CLUSTER and BAM_CLUSTER) of the domain in its member list.

While creating the domain we accepted all the default setting for defaultCoherenceCluster, also name of the cluster in both the domain was same, so it seems it was not able to differentiate between weblogic clusters in both the domain and hence all the running servers were getting registered under only one cluster name SOA_CLUSTER.

Solution: 

we removed the SOA_CLUSTER and BAM_CLUSTER from the member list of defaultCoherenceCluster in one of the domain.

Alternatively other solution could be to create 2nd domain with different cluster name.

Although i am not sure if configuring defaultCoherenceCluster is mandatory or not :) 

since it resolved the issue for me , we accepted this solution.

Thanks a lot for your patience!!!

Error while bringing up the server after changing the repository schema password in 12c 

Hello Viewer,

In my case business requires the Metadata Repository schema passwords to be changed on a regular basis.
I changed the password for all the repository schema but after changing the password as soon as i started the managed and Admin server , it was failing to restart.

Below was the error in logs:

Error Code: 28000 Mar 20, 2016 2:48:19 AM oracle.security.jps.internal.common.config.AbstractSecurityStore getSecurityStoreVersion WARNING: Unable to get the Version from Store returning the default oracle.security.jps.service.policystore.PolicyStoreException: javax.persistence.PersistenceException: Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.5.2.v20140319-9ad6abd): org.eclipse.persistence.exceptions.DatabaseException Internal Exception: java.sql.SQLException: ORA-28000: the account is locked

After checking with the database team MFT_OPSS account was getting locked.
Although I checked that except datasource we are not using the MFT_OPSS user anywhere else. But still again and again it was getting locked. From SQL developer also we were able to connect successfully and the same password was updated in datasource as well.

Cause:

A 12c Infrastructure uses a Java Platform Security (JPS) credential store. If the credentials in the JPS store do not match with OPSS schema credentials in the Metadata Repository, AdminServer and Managed server will fail to start.

Note: Above error applies to Oracle Fusion Middleware - Version 12.1.2.0.0 and later

Solution:

It was resolved after following the below steps:

1) I asked the database team to unlock the account and change the password for this user,

2)  Encrypted the password using below steps and updated the opss-datasource-jdbc.xml
         a) cd $DOMAIN_HOME/bin
             . ./setDomainEnv.sh

         b) java weblogic.security.Encrypt newpassword

3) $ORACLE_HOME/oracle_common/common/bin/wlst.sh

wls:/offline>modifyBootStrapCredential(jpsConfigFile='$DOMAIN_HOME/config/fmwconfig/jps-config.xml',username='MFT_OPSS',password='newpassword')

4) Try to bring up the Admin server and Managed server. Hopefully it will start without any error this time.

Thanks a lot for your patience!!!

[12.2.1.0.0]Health status showing as blank for JMS servers in clustered environment

Hello to viewer,
After creating the weblogic 12c[12.2.1.0.0] environment , we encountered an issue where active destinations were not showing under jmsserver monitoring tab.

When viewing the Summary of JMS Servers in Weblogic Console the Health status was showing as blank for managed servers even though the managed servers were running and health was OK on summary of servers page.

After going through the oracle notes, we came to know that the issue is actually a bug in new weblogic upgraded version(12.2.1.0.0) which is not there in earlier versions.

As a solution oracle has provided a Patch 21830665 for weblogic version 12.2.1.0.0

This bug has been fixed in next version : 12.2.2.0.0

Note: Issue exist only for clustered environment and not for stand alone server.

Thanks for you patience!!

Thanks and Regards

Script to target/untarget multiple datasource to/from the   cluster

Hello to Viewers,
This script will help in performing the target and untarget operation on multiple datasource in one go. You don't need to go to the console and do the same task manually which is of-course time taking and error prone.

FLOW:

shell script ---> python --> wlst command.

Here shell script will call python script and in python we have mentioned few relevant wlst command that perform the actual task.

Follow the below steps:

1) Create a shell script under below directory: QueueOperation.sh

I have taken the directory structure as below:

/opt/soauser/automation/SOADataSourceOperation/


DataSourceOperation.sh

----------------------------------------------------------------------------------------------

#!/bin/sh

export LOGFILE="/opt/soauser/automation/SOADataSourceOperation/DataSource.log"

if [ -f $LOGFILE ]; then

  rm -f $LOGFILE

fi

rm -rf /opt/soauser/automation/SOADataSourceOperation/DataSource.log

WL_HOME="/xxxxxx/xxxx/xxx/wlserver_10.3"

export WL_HOME

echo "Please enter target to Target and untarget to Untarget the Datasources:"

read PARAMETER1

cd /opt/soauser/automation/SOADataSourceOperation/

sh ${WL_HOME}/common/bin/wlst.sh /opt/soauser/automation/SOADataSourceOperation/DataSourceOperation.py $PARAMETER1 $1 >> /opt/soauser/automation/SOADataSourceOperation/DataSource.log

exit

------------------------------------------------------------------------------------------------

2) Create a text file in same directory that contains the datasource name:

Suppose you need to untarget the datasource related to SAP then name it as SAPdsList.txt(targetdsList.txt)

here target could be SAP or any end system to which datasources are related.

SAPdsList.txt

-----------------------------------------------------------------------------------------------------

DSNAME1
DSNAME2

------------------------------------------------------------------------------------------------------

3) Create a python file under the same directory: DataSourceOperation.py

Here i am assuming that 

datasources are targeted to only weblogic cluster.

DataSourceOperation.py

------------------------------------------------------------------------------------------------------

from java.io import FileInputStream

import java.lang

import os

import string

import sys , traceback

operation=sys.argv[1]

target=sys.argv[2]

def connectToServer():

        USERNAME = 'username'

        PASSWORD = 'password'

        URL='t3://AdminServerhost:AdminServerport'

        #Connect to the AdminServer

        print 'starting the script ....'

        connect(USERNAME,PASSWORD,URL)

def disconnectFromServer():

    print "Disconnecting from the Admin Server"

    disconnect()

    print "Exiting from the Admin Server"

    exit()

    print "Mission Accomplished"

def Target(DSName):

     try:

        print 'Entry point1...'

        edit()

        tgName = 'CLUSTER_NAME'

        startEdit()

        DSName = DSName.strip()

        print 'test0'

        cd ('/JDBCSystemResources/'+ DSName)

        print 'test1'

        set('Targets',jarray.array([ObjectName('com.bea:Name='+tgName+',Type=Cluster')], ObjectName))

        activate()

        print 'DataSource: "', DSName ,'" has been TARGETED TO CLUSTER Successfully'

     except :

        print 'Something went wrong...'

        exit()

def Untarget(DSName):

     try:

        print 'Entry point1...'

        edit()

        tgName = 'CLUSTER_NAME'

        startEdit()

        DSName = DSName.strip()

        print 'test0'

        cd ('/JDBCSystemResources/'+ DSName)

        print 'test1'

        set('Targets',jarray.array([], ObjectName))

        activate()

        print 'DataSource: "', DSName ,'" has been UNTARGETED FROM CLUSTER Successfully'

     except :

        print 'Something went wrong...'

        exit()

###############     Main Script   #####################################

#Conditionally import wlstModule only when script is executed with jython

if __name__ == '__main__':

    from wlstModule import *#@UnusedWildImport

print('This will enable you to perform operation on  datasource')

listName = target+'dsList.txt'

if operation=='target':

   f = open(listName,'r')

   out = f.readlines()

   for DSName in out:

     DSName.strip()

     print 'Trying to target  '+DSName

     connectToServer()

     Target(DSName)

     disconnect()

     print 'Target the '+DSName

else:

   f = open(listName,'r')

   out = f.readlines()

   for DSName in out:

     DSName.strip()

     print 'Trying to untarget '+DSName

     connectToServer()

     Untarget(DSName)

     disconnect()

     print 'Untargeted the '+DSName

disconnectFromServer()

-------------------------------------------------------------------------------------------------------

HOW TO RUN:

Simply run the shell script and provide the target system name as a parameter for ex:

cd /opt/soauser/automation/SOADataSourceOperation/

sh DataSourceOperation.sh SAP 

(here SAP is the target so python file will look for SAPdsList.txt)

then it will ask for the operation to be performed : Please enter target to Target and untarget to Untarget the Datasources

type the operation name and press "enter" and then verify the log file(DataSource.log) and queue status from console.

Thanks a lot for your patience !!!!
