Phyton ile NodeManager, Admin Server ve Managed Serverleri baslatma

        Merhaba, cok uzun bir baslik oldu sanirim :), evet konu basligindanda anlasildigi gibi, phyton scripti kullanarak, NodeManager`imizi start edip, daha sonra NodeManager baglanip, Admin ve Managed Servlerimizi start edecegiz.

Bu islem icin bize iki tane dosya gerekmektedir. 

• domain.properties
• ve scriptimizin oldugu NodeManager_AdminServer_Start.py diger dosyamiz

domain.properties dosyamizin icerigi

username=weblogic

password=wadmin12

host=localhost

nm.port=5556

domain.name=lab_domain

domain.dir=/u01/app/oracle/Middleware/user_projects/domains/lab_domain

nm.type=ssl

admin.server.name=AdminServer

managed.server.name=j2eeServer

NodeManager_AdminServer_Start.py dosyamizin icerigi

Bir sonraki makalemizde, managed Serverlarimiza, bir .war dosyasi deploy edip, biri kapandiginda digeri ile nasil baglanacagimizi gorecegiz.

Weblogic Node Manager

    Merhaba, bu makalemizde weblogic yazi dizimizin devami olan Node Manager nedir, nasil kurulur ve nasil kullanilir bunu goruyor olacagiz.
  
1.  Node Manager nedir. 
    Once sunu belirmeliyim ki, Node Manager weblogic serveri urun(production) ortaminda zorunlu degildir. Yani Node manager olmadan,  weblogic server`inizi, admin server, managed server ve cluster`larinizi yonetebilirsiniz. Peki, Node Manager olmadan, biz bunlari yapabiliyorsak Node Manager`a neden ihtiyac duyuyoruz.? diye bir soru akillara gelecektir. 
Bunu ornekle aciklayalim.
  Dusunun ki, Weblogic Serverimiz ve bunun icinde birden fazla domain ve machine`lar var ve bunlarda ayri ayri lokasyonlarda, bu durumda bunlari idare etmemiz, bu domainle iliskili olan Admin Server ve Managed Servleri nasil start, stop ve monitor etmek zor bir durum olacaktir. Iste bu noktada Node Manager aklimiza geliyor. Hatirlayalim, Node Manager, fiziksel makine uzerinde calisan bir processdir. Bize uzakdan Admin server, Managed Server`larimizi start, stop ve monitor etmemize yarar. 
  Node Manager, spesifik bir domain ile iliskili degildir, fiziksel bir makine ile iliskilidir. Ve machine logical bir yapidir.

Yukaridaki sekilde WLST kullanarak Node Manager`a baglandikdan sonra Serverlarin yonetilmesini gosterir

2. Node Manager nasil kurulur.
 Node Manager, iki sekilde kullanilabilir. Java-based ve Script based.
 Guvenlik acisindan Node Manager`i java-based olarak kullanmak script based`dan daha guvenlidir. Bu makalemizde, daha anlasilir olmasi acisindan script tabanli olacaktir.
 a. Oncelikle Admin console acarak, Environmets -> Machines -> bolumunden machine yoksa, yeni bir nachine olusturup, bu machine uzerinde node manager olustururak servlerimizi yonetecez.

 Save diyerek, Node Manager`imizi olusturuyoruz.

3. Nasil Kullanilir.
  Yukarida Node Manager`in ne oldugundan bahsettikden, daha sonra, nasil olusturulacagini gorduk, simdide nasil kullanicagimizi ve Admin ve managed serverlerimizi nasil start, stop ve monitor edecegimizi gorecegiz.
- Ortam degiskenlerimizi set ediyoruz.

    /u01/app/oracle/Middleware/wlserver_12.1/bin/setWLSEnv.cmd    

- WLST baslatiyoruz.

java weblogic.WLST

-   Node Manager`i baslatiyoruz.

startNodeManager(verbose='true', NodeManagerHome='/u01/app/oracle/Middleware/wlserver_12.1/common/nodemanager/', ListenPort='5556', ListenAddress='localhost')

- Node Manager`a baglaniyoruz.

nmConnect('weblogic','wadmin12','localhost','5556','lab_domain','/u01/app/oracle/Middleware/user_projects/domains/lab_domain/','ssl') 

- Admin server eklenmesi icin, boot.properties dosyasini ekliyoruz.

/u01/app/oracle/Middleware/user_projects/domains/lab_domain/servers/AdminServer/security/ 
   boot.properties
   
Bu dosyayi, /u01/app/oracle/Middleware/user_projects/domains/lab_domain/servers/AdminServer/security/
altindan kopyalayip ekleyebiliriz.

- connect('weblogic','wadmin12','t3://localhost:7001')
- Admin Server`i start etmek icin,

nmStart('AdminServer')

-  Admin Server statusunu ogrenmek icin

nmServerStatus('AdminServer')

- Admin Server`i durdurmak icin

nmKill('AdminServer')

- Managed serverlarida ayni Admin Server gibi start, stop edebiliriz.

 nmStart('j2eeServer')

 nmStart('portalServer')

 nmKill('j2eeServer')

- Node Manager`i start ve stop etmek icin

startNodeManager()

stopNodeManager() 

 - Admin consol uzerinde, machine inactive veya unreachable olarak gorunurse, asagidakini eklememiz gerekmektedir.  
   nmEnroll('/u01/app/oracle/Middleware/user_projects/domains/lab_domain/','/u01/app/oracle/Middleware/wlserver_12.1/common/')

weblogic domain silme

       Merhaba, bu makalemde weblogic server uzerinde daha onceden olusturmus oldugumuz bir domain`i nasil silecegimizi paylasacagim.
   
   Weblogic serverden bir domain silmek icin, asagidaki adimlari takip ediyoruz.

1. Weblogic Home klasourunuz altindaki domain-registry.xml dosyasinin icinden domainimizi siliyoruz.
  [ertugrula@localhost middleware]$cd /u01/app/oracle/middleware/
         domain location="/u01/app/oracle/middleware/user_projects/domains/myDomain"

2.  weblogic home altindaki wlserver_12.1/common/nodemanager/ klasorun icindeki nodemanager.domains
     dosyasinin icindeki domain bilgilerimizi siliyoruz.

3.  Ve son olaraka weblogic home altindaki /u01/app/oracle/middleware/user_projects/domains/   domain        klasorumuzu siliyoruz.

weblogic WLST ile Domain olusturma

"WLST" Weblogic Scripting tool  komut satırından sunucuları idare etme,  yeni domain oluşturma veya yonetme ve monitor etmek icin kullanılan Jython uygulamasıdır. Jython, populer phyton dilinin java implementasyonu olan bir dildir. WL_HOME\common\templates\scripts\wlst klasöründe weblogic gelistiricileri tarafindan yazilan örnek scriptler bulabilirsiniz.

     Bu makalemizde, WLST kullanarak bir domain olusturacaz.
WLST'yi kullanmak için öncelikle WL_HOME\common\bin\wlst.bin veya sh dosyanın çalıştırılması gerekiyor. Eğer orjinal template'den oluşturmak için aşağıdaki komut yeterlidir.

    createDomain(domain Template, domain Dir, user, password);

Simdi biz gelelim script ile olusturmaya. Bunun icin once bir create_domain.py isminde bir dosya olusturup icerisine asagidaki kodlari ekliyoruz ve asagidaki sekilde baslatiyoruz. Ben kendi makinemde /home/ertugrula/weblogic_blog/create_domain.py altinda olusturdum.

[ertugrula@localhost bin]$ pwd

/u01/app/oracle/middleware/wlserver_12.1/common/bin

[ertugrula@localhost bin]$ sh wlst.sh /home/ertugrula/weblogic_blog/create_domain.py

create_domain.py dosyasinin icerigi

#=======================================================================# Open a domain template.

#=======================================================================

readTemplate("/u01/app/oracle/middleware/wlserver_12.1/common/templates/domains/wls.jar")

addTemplate("/u01/app/oracle/middleware/wlserver_12.1/common/templates/domains/geo1domain.jar")

cd('Servers/AdminServer')

set('ListenAddress','lcoalhost')

set('ListenPort', 7001)

create('AdminServer','SSL')

cd('SSL/AdminServer')

set('Enabled', 'True')

set('ListenPort', 7002)

#=======================================================================

# Define the user password for weblogic.

#=======================================================================

cd('/')

cd('Security/base_domain/User/weblogic')

cmo.setPassword('wadmin12')

# Please set password here before using this script, e.g. cmo.setPassword('value')

#=======================================================================

# Write the domain and close the domain template.

#=======================================================================

setOption('OverwriteDomain', 'true')

writeDomain('/u01/app/oracle/middleware/user_projects/domains/mydomain')

closeTemplate()

#=======================================================================

# Exit WLST.

#=======================================================================

exit()

nutch content store

Merhaba, Apache Nutch kullanarak, web sitelerinizi crawl etmek istediginizde, default olarak crawl ederken html icerigini crawl edip indexlemez, bunun icin asagidaki satiri duzeltmemiz isimizi gorecektir.

Mesala ben solr`a indexledigim icin (solr 4.0)

../solr/example/solr/collection1/conf/schema.xml icerisinde asagidaki stored kismini true yapiyoruz
true
field name="content" type="string" stored="true" indexed="true"/

org.apache.solr.common.SolrException: undefined field text

Exception: 
org.apache.solr.common.SolrException: undefined field text 

Solution: 
1. open solrconfig.xml 
2. find
3. under that tag, find  text

4. change "text" to whatever your entity property that you need it to be indexed

For example, if I have an entity called car, it might have a property called brand and I might want to search within that field. So, in that case it would be convenient for me to change "text" to "brand"
