Stop and uninstall an application using wsadmin

Before the application can be unsinstalled it must be stopped.
Steps:

1. Open wsadmin (with jython)
1.1 Go to "WebSphere_Profile_Root"/bin
1.2 Execute

wsadmin.sh(.bat) -lang jython

1.3 Enter UserID/Password (if promted)

2. Define needed cell and node variables
2. Execute

cell=AdminConfig.list('Cell')
cellname=AdminConfig.showAttribute(cell,'name')
nodes=AdminConfig.list('Node',cell)
nodename=AdminConfig.showAttribute(nodes,'name')
-----------------------------------
(Alternative:
e.g.: nodename=NAME_OF_NODE)

3. Define application manager variable

3.1 Execut

appManager=AdminControl.queryNames
('type=ApplicationManager,cell='+cellname+',
node='+nodename+',process=<APP_SERVER_NAME>,*')

3.2 To print out variable execute

print appManager

4. Assign application to variable
4.1 Execute

app=AdminControl.queryNames
('type=Application,cell='+cellname+',node='+nodename+',
process=<APP_SERVER_NAME>,J2EEName=<NAME_OF_APPLICATION>,*')

4.2 To print out variable execute

print app

5. Define application name to variable
5.1 Execute

appName=AdminControl.getAttributes(app,'name')

5.2 To print out variable execute

print appName

6. Stop application
6.1 Execute

AdminControl.invoke(appManager,'stopApplication', appName)

7. Uninstall application
7.1 Execute

AdminApp.uninstall(appName)

8. Save changes
8.1 Execute
AdminConfig.save()


Hint:
It is easier to use administrative console :-)
<APP_SERVER_NAME> = Name of server (JVM) where the application is deployed
<NAME_OF_APPLICATION> = Name of the application (not the ear-files name)

Install and start an application using wsadmin

opy the application ear-file to <WAS_PROFILE_ROOT>/installableApps

1. Open wsadmin (with jython)
1.1 Go to "WebSphere_Profile_Root"/bin
1.2 Execute

wsadmin.sh(.bat) -lang jython

1.3 Enter UserID/Password (if promted)

2. Define needed cell and node variables
2. Execute

cell=AdminConfig.list('Cell')
cellname=AdminConfig.showAttribute(cell,'name')
nodes=AdminConfig.list('Node',cell)
nodename=AdminConfig.showAttribute(nodes,'name')
-----------------------------------
(Alternative:
e.g.: nodename=NAME_OF_NODE)

3. Install application
3.1 Execute
AdminApp.install('../installableApps/<NAME_OF_EAR_FILE>',['-appname <NAME_OF_APPLICATION>'])

4. Save changes
4.1 Execute

AdminConfig.save()

5. Define application manager variable

5.1 Execute

appManager=AdminControl.queryNames
('type=ApplicationManager,cell='+cellname+',
node='+nodename+',process=,*')

5.2 To print out variable execute

print appManager

6. Assign application to variable
6.1 Execute

app=AdminControl.queryNames
('type=Application,cell='+cellname+',node='+nodename+',
process=,J2EEName=,*')

6.2 To print out variable execute

print app

7. Define application name to variable
7.1 Execute

appName=AdminControl.getAttributes(app,'name')

7.2 To print out variable execute

print appName

8. Start application
8.1 Execute

AdminControl.invoke(appManager, 'startApplication',appName)

Hint:
It is easier to use administrative console :-)
<APP_SERVER_NAME>= Name of server (JVM) where the application is deployed
<NAME_OF_APPLICATION> = Name of the application (not the ear-files name)

Modifying the starting weight of applications using scripting (jython)

1. Update the starting weight of an Enterprise Application:

AdminConfig.modify
(AdminConfig.showAttribute
(AdminConfig.getid("/Deployment:myApps/"),
"deployedObject"),[['startingWeight','20']])

Note: Valid range for 'startingWeight': 0 and 2147483647

2. Update the class loader mode of an Enterprise Application:

AdminConfig.modify
(AdminConfig.showAttribute(AdminConfig.showAttribute
(AdminConfig.getid('/Deployment:myApps/'),'deployedObject'),
'classloader'),[['mode','PARENT_LAST']])

Note: Valid values for 'mode' : PARENT_FIRST, PARENT_LAST

3. Update the WAR class loader policy of an Enterprise Application:

AdminConfig.modify
(AdminConfig.showAttribute
(AdminConfig.getid('/Deployment:myApps/'),
'deployedObject'),[['warClassLoaderPolicy','SINGLE']])

Note: Valid values for 'warClassLoaderPolicy':
SINGLE (Application), MULTIPLE (Module;default)

4. Update the starting weight of individual modules (Web or EJB) within an EAR -->

def modifyModStartingWeight(appName, modStWeight, modName):
    global AdminConfig
    try:
        refParam = "/Deployment:" + appName + "/"
        depRef = AdminConfig.getid(refParam)
        depObjectRef = AdminConfig.showAttribute(depRef, 'deployedObject')
        modules = AdminConfig.showAttribute(depObjectRef, 'modules')
        arrayModules = modules[1:len(modules)-1].split(" ")
        for module in arrayModules:
        tmpStr = AdminConfig.showAttribute(module,'uri')
                if tmpStr == modName:
                        AdminConfig.modify(module, [['startingWeight', modStWeight]])
                        print "New starting weight for " +
AdminConfig.showAttribute(module,'uri') + "is " +
AdminConfig.showAttribute(module,'startingWeight')
        try:
            AdminConfig.save()
        except:print "AdminConfig.save() caught exception. \n"
    except: print "AdminConfig.modify(" + appName + ") caught

wsadmin rotate jvm log files

Simple, working, rotates logs at 10mb saving max 5 files.

# rotateWasLogEPRN.py
# Setup WAS Log file rotations
# for yourserver
# 9/10/2008
# Mike Huffsteder - WTA
#
# Implement:
# ./wsadmin.sh -lang jython -f $FILE_LOCATION/rotateWasLogEPRN.py >> $TO_LOG_FILE
#
# You can add this as you have other scripts in the deployment script
# if you need help please let me know.
#
#

print "Changing the SystemOut & SystemErr log file rotation settings"
var1 = AdminConfig.getid('/Cell:yourcell/Node:yournode/Server:yourserver/')

log = AdminConfig.showAttribute(var1, 'outputStreamRedirect')
log2 = AdminConfig.showAttribute(var1, 'errorStreamRedirect')

AdminConfig.modify(log, '[[rolloverSize 10] [maxNumberOfBackupFiles 5]]')
AdminConfig.modify(log2,'[[rolloverSize 10] [maxNumberOfBackupFiles 5]]')

AdminConfig.save()

print "New SystemOut settings 9-10-08"
AdminConfig.show(log).split("\n")
print "New SystemErr settings 9-10-08"
AdminConfig.show(log2).split("\n")

Dissable security

To disable global security either edit the security.xml file or use the wsadmin tool.




$WAS_HOME\config\cells\cellname\security.xml



Using WAS command-line client wsadmin (run with was user or root privileges):

1. Open a connection to local WAS in offline mode

wsadmin -conntype NONE



2. Turn off global security

wsadmin> securityoff



3. Save

wsadmin> $AdminConfig save

How to increase the heap size from wsadmin

How to increase the heap size from wsadmin

AdminTask.setJVMInitialHeapSize( ‘[ -nodeName ' + n + ' -serverName ' + s + ' -initialHeapSize ' + str( 384 ) + ' ]‘ )


AdminTask.setJVMMaxHeapSize( ‘[ -nodeName ' + n + ' -serverName ' + s + ' -maximumHeapSize ' + str( 944 ) + ' ]‘ )

# or you could set a bunch of JVM properties in one call

AdminTask.setJVMProperties( ‘[ -nodeName ' + n + ' -serverName ' + s + ' -initialHeapSize ' + str( 384 ) + ' -maximumHeapSize ' + str( 944 ) + ' -verboseModeGarbageCollection true ' + ' ]‘ )
