How to Auto start Weblogic Domain through WLST

 

The Following Script checks the health of Weblogic Domain when configured as corn job, it connected to domain admin servers if its up if adminserver is down it will start the admin server before proceeding further. Expectation of this script is Nodemanager is running in all the machines hosting the domain.

 

We need two files one is the environment Properties file and one python script.

<evn>.<properties> file will have following information need to update according to the environment.

# Environment Specific Values need to updated below

LOGS=/home/oracle/logs

How to deploy multiple SOA composites using WLST

Following post describes the process to deploy multiple soa composites .

Step1 . Create a file with list of soa composites that are needed to deploy.

Stpe2 . Create env.properties file with environment details

env.properties

soa.soa_server = http://<SOA Server Address>:<Port>
soa.jar_location = <Path to SAR Files>/sar/
soa.xml_location = <Path to Config Plan>/configPlan/
soa.username = weblogic
soa.password = <weblogic password>

Step 3. Create soadeploy.py

from java.io import FileInputStream

propInputStream = FileInputStream("env.properties")
configProps = Properties()
configProps.load(propInputStream)
soa_server = configProps.get("soa.soa_server")
jar_location = configProps.get("soa.jar_location")
config_location = configProps.get("soa.xml_location")
username = configProps.get("soa.username")
password = configProps.get("soa.password")
composites = [line.strip() for line in open('soa_list')]
configpath = config_location + "soa_cfgplan.xml"
error_occurred = False
failed_composites = []
for composite in composites:
    print "----------------------------------------------------------------------------------------"
    print 'Attempting to deploy: ' + composite
    try:
        sca_deployComposite(soa_server,jar_location + composite,true,username,password,true,configpath)

    except:
        print 'Failed to deploy: ' + composite
        print "Exeception info: ", sys.exc_info()[0]
        error_occurred = True
        failed_composites.append(composite)
    print "----------------------------------------------------------------------------------------"
if error_occurred:
    print "\nThe following soa composites failed to deploy:"
    for failure in failed_composites:
        print failure
else:
    print "\nAll soa composites deployed successfully!"
print "\nDone."
exit()

How to check the files existing in particular directory in bash script (UNIX)

 

In order to verify list of file names are existing  in particular location in Unix  we can use the if function to verify if the file is exists in the given path or not.

We need to read the list files which we need to verify . To just read the file names only on a given location we can use the ls command with additional option like below.

ls --file-type –1 <path location> | grep -v '/' >file_list

when the above command is executed the file_list will have all the filenames on the path location mentioned on the command

Once we read the list of file names we can verify those files exists in particular location or not by using below function

for filename in `cat file_list`
do
    if [ -a ${path}/$filename ];
        then   
                echo “ File exists in the $path”
        else        
                echo " File is NOT  found "
    fi
done

How to use Xming/XLaunch to invoke the GUI on Linux servers

 

In order to invoke the GUI Interface for any application installation in oracle/ibm stacks or any other GUI mode of installation is easy .

There are variety of tools available to invoke the gui from Linux servers like vncserver . In this post I will brief about xming which is one of tools used to invoke the GUI.

Download the xming from http://sourceforge.net/projects/xming/   or any other location from web.

Install the xming binaries, once you install you can see XLaunch on your applications/Desktop. click on XLaunch

 

 

On the Display number you can choose to give any number here in example I have given 20 and then click next

click next

click next

click Finish

once we configured the XLaunch we need to update x11 on the putty to use the XLaunch. open the putty

under the X11 forwarding check the box for Enable X11 forwarding and in X display location provide the following.

localhost:20 ( which we have chosen as Display Number)

Now connect to the server

once login to the servers please execute the following commands.

xauth list    ( this command will list the xauth listeners running on the server) copy the latest one and execute below command

xauth add <>  ( you need to paste the line you have copied in above step)

Now you can invoke xclock from your console which will open the clock on your desktop for testing the connectivity.
