4. AGENDA
Motivation „Infrastructure as Code“
Überblick WebLogic Scripting Tool
Best Practices Administration und Deployment
Andreas Koop 4

5. INFRASTRUCTURE AS CODE
‣ Vision - Bereitstellung einer
lauffähigen Umgebung aus
‣ Source Code Repository
‣ Anwendungsdaten (Backup)
‣ Ressourcen (Physikalisch /
Virtuell)
‣ In Zeiten von Cloud und steigendem Bedarf nach horizontal skalierbaren
System ist IaC unabdingbar
Andreas Koop 5

6. RESTORE ENV FROM CODE
app source
App
App
SCM App
Artefacts
Artefacts
Artefacts
infra source
DB / Service
Endpoints configuration / Sh, Chef, WLST, ...
data /
backup
Andreas Koop 6

7. WAS BRAUCHT EINE
ORACLE FMW UMGEBUNG?
‣ WebLogic Installation, Domain ‣ WebLogic Konfiguration
‣ Application Deployment ‣ Data Sources
‣ System and Performance ‣ Message Queues
Monitoring
‣ Logging
‣ Diagnostics (WLDF)
App1 App2
‣ Security Provider
‣ ...
Andreas Koop 7

8. MANUELLE KONFIGURATION
IST KEINE LÖSUNG
Andreas Koop 8

9. WEBLOGIC SCRIPTING TOOL
‣ Jython basierte Scriptsprache zur Automatisierung jeglicher WebLogic
Administrationsaufgabe
‣ Read / Write MBeans
‣ Offline
‣ ~ Configuration
Wizard
‣ Online
‣ ~ Administration Console
Andreas Koop 9

10. DOMAIN ERSTELLEN
readTemplate(os.environ['WL_HOME'] + '/common/templates/
domains/wls.jar')

setOption( "ServerStartMode", "prod")
setOption( "OverwriteDomain", "true" )
writeDomain( DOMAIN_DIR )
closeTemplate()

11. DOMAIN ERWEITERN
# Z.B. um die ADF Runtime in Form der JRF
readDomain(DOMAIN_DIR)
addTemplate(MW_HOME + '/oracle_common/
common/templates/applications/jrf_templ
ate_11.1.1.jar')
updateDomain()

12. WLST EXECUTION
BEST PRACTICE (OFFLINE)

22. LOGGING LOGGING LOGGING
‣ Never-Ending-Story
‣ Was tun? Was berücksichtigen?
‣ Log Rotating
‣ Domain Log
‣ Server Logs
‣ „Wo sind die Log-Files???“
Andreas Koop 22

23. LOGGING KONFIGURATION
execfile('connect.py')
execfile('start.edit.session.py')
cd('/Servers/AdminServer/Log/AdminServer')
cmo.setStacktraceDepth(5)
cmo.setRotationType('bySize')
cmo.setDomainLogBroadcasterBufferSize(10)

24. DEPLOYMENT
‣ Data Source vorbereiten
Java EE App
‣ Targets
deploy
‣ Deploy
‣ Application
‣ Shared Libs App1 App2
‣ EJBs
Andreas Koop 24

25. DATA SOURCE ANLEGEN
‣ JNDI Lookup
#connect(..), edit() startEdit()
cd('/')
create('myDataSource', 'JDBCSystemResource')
cd('JDBCSystemResource/myDataSource/JdbcResource/myDataSource')
create('myJdbcDriverParams','JDBCDriverParams')
cd('JDBCDriverParams/myDSName')
set('DriverName','oracle.jdbc.OracleDriver')
set('URL','jdbc:oracle:thin:@localhost:1521:XE')
set('Password', 'HR')
set('UseXADataSourceInterface', 'false')
create('myProps','Properties')
cd('Properties/myDSName')
create('user', 'Property')
cd('Property/user')
cmo.setValue('HR')
..
cd('/JDBCSystemResource/myDataSource/JdbcResource/myDataSource')
create('myJdbcDataSourceParams','JDBCDataSourceParams')
cd('JDBCDataSourceParams/myDSName')
set('JNDIName', java.lang.String("jdbc/hrDS"))
Andreas Koop 25

26. DATA SOURCE
ENCRYPTED PASSWORD

27. APPLICATION DEPLOYMENT
‣ 2 Phasen
Java EE App
‣ Vorbereiten
‣ Deployment Durchführen deploy
‣ Modi
‣ No Stage App1 App2
‣ Stage
‣ External Stage
Andreas Koop 27

28. HOW TO DEPLOY
connect('weblogic', 'welcome1', ADMIN_URL)
deploy('myApp', '/path/to/myApp.ear', targets='Cluster1')
# targets='Server1'
startApplication('myApp')
disconnect()
exit()
Andreas Koop 28

29. HOW TO UNDEPLOY
connect('weblogic', 'welcome1', ADMIN_URL)
stopApplication('myApp')
undeploy('myApp')
# default: from all targets
disconnect()
exit()
Andreas Koop 29

30. DEPLOYMENT COMMANDS
Command
deploy(appName, path, [targets], [stageMode], [planPath], [options])
startApplication(appName, [options])
stopApplication(appName, [options])
undeploy(appName,[targets],[options])
Mittels plan.xml
updateApplication(appName, [planPath], [options])
aktualisieren
listApplications()
Andreas Koop 30

31. HOW TO RELAX
(CUSTOM SOLUTION) Keep last 10 EARs
‣ ...falls das Deployment mal 2012-08-02-myapp.ear
2012-08-02-myapp.ear
2012-08-02-myapp.ear
nicht reibungslos läuft?
‣ Deploy And Backup EAR deploy(...)
shutil.copy(...)
‣ Restore def restore():
#Get last EAR
#deploy(lastEAR)
myapp
Andreas Koop 31

32. SIDE-BY-SIDY DEPLOYMENT
deploy('myApp', '/path/to/myApp.ear', ..,appVersion = '1.0')
Bestehende Client-
Verbindungen
app v1.0 app v2.0
Neue Client-
Verbindungen
deploy('myApp', '/path/to/myApp.ear', ..,appVersion = '2.0')
Andreas Koop 32

33. SERVER MONITORING
..
state('<ServerName>')
..
domainConfig()
serverNames = cmo.getServers()
domainRuntime()
for name in serverNames:
cd("/ServerRuntimes/"+name.getName()+"/JVMRuntime/"+name.getName())
heapFree = int(get('HeapFreeCurrent'))/(1024*1024)
heapTotal = int(get('HeapSizeCurrent'))/(1024*1024)
heapUsed = (heapTotal - heapFree)
print '%14s %4d MB %4d MB %4d MB' % (name.getName(),heapTotal, heapFree, heapUsed)
Andreas Koop 33

34. SERVER THREAD DUMP
..
threadDump(writeToFile='true',fileName='/tmp/threaddump.txt',
serverName='AdminServer')
..
Andreas Koop 34

35. DOMAIN CONFIG AS CODE
Domain Configuration
wls:offline>configToScript(configPath='$DH',
pyPath='config.mydomain.py')
MDS per Application
wls:online>exportMetadata(application='doag-
demo', server='AdminServer', toLocation='/tmp/exportmds'
User / Groups Embedded LDAP
wls:online> domainRuntime() cd(‘/DomainServices/
DomainRuntimeService/DomainConfiguration/<domain>/
SecurityConfiguration/<domain>/DefaultRealm/myre alm/
AuthenticationProviders/DefaultAuthenticator’)
cmo.exportData('DefaultAtn', '/export.ldif', Properties())
Andreas Koop 35

36. WLST RECORDING FEATURE
‣ WebLogic Console Record (Aufzeichnen)-Button klicken
‣ Gewünschte Konfiguration vornehmen
‣ Generiertes WLST-Skript anpassen und integrieren
Andreas Koop 36

37. CONCLUSION
‣ WLST RULEZ!
‣ MUST for every Oracle FMW Admin!
‣ Vollständige Automatisierung von
‣ Domainerstellung, -konfiguration
‣ Application, Library Deployment
‣ Export / Import MDS
‣ Server - Startup / Shutdown - Monitoring
Andreas Koop 37
