第4回は、第3回で実施したコマンドラインでの設定、情報採取をさらに改良してみます。

第2回のアプリケーションサーバー構築時と同様にservername の値をserver_listから取り出し、for文で回すことで、複数のアプリケーションサーバーに同じ設定を実施できます。設定完了後、設定情報を取得してみます。

appserver01については第３回で設定済みのため、今回はappserver02～05について設定を行います。

server_list = ('appserver02','appserver03','appserver04','appserver05')
 
for servername in server_list:
     nodename="testNode01"
     server=AdminConfig.getid('/Node:'+nodename+'/Server:'+servername+'/')
     javavirtualmachine=AdminConfig.list("JavaVirtualMachine", server)
     verbosemodegarbagecollection="true"
     initialheapsize=str("1024")
     maximumheapsize=str("1024")
     AdminConfig.modify(javavirtualmachine,    "[[initialHeapSize "+initialheapsize+"]    [maximumHeapSize    "+maximumheapsize+"] [verboseModeGarbageCollection "+verbosemodegarbagecollection+"]]")
 
 
AdminConfig.save()
 
server_list = ('appserver02','appserver03','appserver04','appserver05')
 
for servername in server_list:
     print "----------"+servername+"----------"
     nodename="testNode01"
     server=AdminConfig.getid('/Node:'+nodename+'/Server:'+servername+'/')
     javavirtualmachine=AdminConfig.list("JavaVirtualMachine", server)
     print AdminConfig.show(javavirtualmachine)

これで複数のアプリケーションサーバーのJVMのメモリ設定をコマンドで変更し、設定した値の情報採取が行うことができます。複数のアプリケーションサーバーを同じ設定とする場合に、是非参考にしていただければと思います。

第4回では第3回に引き続き、コマンドラインでのアプリケーションサーバーの設定、情報採取の方法についてご説明しました。
第5回ではwsadminコマンドを利用したアプリケーションのデプロイについて触れたいと思います。
