Booting Weblogic - OOW14
0 likes618 views
This document provides an overview of booting Oracle WebLogic server instances. It discusses the key components involved, including Node Manager and WebLogic Scripting Tool (WLST). It recommends using Node Manager to start the Administration Server and WLST to start managed servers. Sample scripts are provided to start all servers using this approach. The document also covers encrypting credentials, configuring Node Manager as a Windows service, and other tips.

- 5. sysco.no Booting Oracle WebLogic ●WebLogic -advanced and flexible oMakes it a bit complex oMany choices that has to be made ●No out-of-the-box start scripts ●Many resources on the Net oSome good oSome that might not fit your requirements oSome not so optimal
- 6. sysco.no Why automatic/scripted boot ●No user intervention oNo one has to be present (physical or “virtual”) oLess error prone oDo it the same way every time ●Makes it easier to start / stop single instances for the ops staff ●Want services to be restarted automatically if needed ●Use what is available in WLS
- 7. sysco.no Prereqs ●WebLogicinstalled, domaincreated ●Node Manager installedand configured onmEnroll onmGenBootStartupProps ●For demo purposes oNot usingSSL (SecureListener=false in nodemanager.properties) oLittle errorhandling

- 16. sysco.no WebLogic Scripting Tool (WLST) ●WLST is based on Jython (Python) ●Can do pretty much everything with WLST ●Be sure to have correct path (source setDomainEnv.sh) ●Recording option in Admin Console, might be used as starting point for automation
- 17. sysco.no Shell scripts called during boot ●Start Node Manager oinit.d / xinit.d scripts for Linux oScript to create a Windows service ●Start WebLogic oCustom bash/cmd script for starting the AdminServer and managed servers
- 18. sysco.no Different methods Start script Using WLST and Admin Server Using WLST and Node Manager Choose one method and stick with it
- 19. sysco.no Start scripts Generated when a domain is created <domain home>/startWebLogic.sh <domain home>/bin/startManagedWebLogic.sh Works well, but make sure to use nohupand put the process in the background $ nohupstartWeblogic.sh &
- 20. sysco.no Using WLST and Admin Server ●Possible to start AdminServer oNot recommended with Fusion Middleware suite products ●Connect to AdminServer to start managed servers oconnect(userConfigFile=userFile, userKeyFile=keyFile, url=adminUrl) ostart(...)
- 21. sysco.no Using WLST and Admin Server ●Requires oRunning AdminServer oRunning Node Manager oAdminServer communicates with Node Manager ●Node Manager sets the oJAVA_VENDOR, JAVA_HOME, JAVA_OPTIONS oSECURITY_POLICY,CLASSPATH, ADMIN_URL
- 22. sysco.no Using WLST and Node Manager ●Connect to Node Manager onmConnect ●Start AdminServerand managed servers onmStart ●Does not set the variables with information from AdminServer. Possible to provide this information manually along with nmStart
- 23. sysco.no Starting from NodeManager nmConnect(userConfigFile=nmUserFile, userKeyFile=nmKeyFile, host=nmHost, port=nmPort, domainName=domain, domainDir=domainPath, nmType=nmType) nmStart('AdminServer') nmStart('ms1')
- 24. sysco.no Recommendations ●It is recommended to always use Node Manager to start AdminServer and managed servers ●It is recommended to let Node Manager use start script (StartScriptEnabled=true) ●It is recommended to start from AdminServer to give server start arguments and SSL arguments to Node Manager
- 25. sysco.no Our approach ●Enable start script in Node Manager (StartScriptEnabled=true in nodemanager.properties) ●Connect to Node Manager and start AdminServer ●Connect to AdminServer and start managed servers

- 43. sysco.no OS boot scripts -Windows Starting Node Manager as a Windows service is supported out-of-the- box. Follow the instructions in the documentation (or on the next slides) NB! -XrsJVM property for each Managed Server that will be under Node Manager control.
- 44. sysco.no Windows -Node Manager 1. Log in to the machine with Administrator privileges. 2. Open a DOS command prompt window. 3. Change to the DOMAIN_HOMEbindirectory.
- 45. sysco.no Windows -Node Manager 4. Enter the following command: installNodeMgrSvc.cmd 5. After a few seconds, the following message is displayed: Oracle WebLogic <domain-name> NodeManager installed.
