SOA 12.2.1 Clustered Domain Using WLST Script

Hey!

Namaste from Oracle Fusion Middleware world!! In this post, I would like to share the experiment on the SOA domain using WLST for a high availability imposed Clustered Domain.

Prerequisites for SOA cluster domain configuration



  1. Oracle Fusion Middleware Infrastructure
  2. Oracle SOA 12.2.1 Installation
  3. Oracle OSB 12.2.1 Installation

Clustered SOA Domain using WLST preparation

High availability can be achived when we configured multiple WebLgoic managed servers and they are part of a cluster. Here in this case 'soa_server1', 'soa_server2' are configured into the 'soa_cluster'.

Step 1: Create the below soa_domain.properties file
WLHOME      = /home/oracle/products/12.2.1/Oracle_Home/wlserver
ORACLE_HOME = /home/oracle/products/12.2.1/Oracle_Home
DOMAIN      = soa_qa_domain
DOMAIN_PATH = /home/oracle/wls_domains/domains/soa_qa_domain
APP_PATH    = /home/oracle/wls_domains/applications/soa_qa_domain
 
SERVER_ADDRESS = 192.168.xxx.xxx
LOG_FOLDER     = /var/log/weblogic/
 
JSSE_ENABLED     = true
DEVELOPMENT_MODE = true
WEBTIER_ENABLED  = false
 
ADMIN_SERVER   = AdminServer
ADMIN_USER     = weblogic
ADMIN_PASSWORD = weblogic1
 
JAVA_HOME      = /home/oracle/jdk1.8.0_65
 
ADM_JAVA_ARGUMENTS = -XX:PermSize=256m -XX:MaxPermSize=512m -Xms1024m -Xmx1532m 
OSB_JAVA_ARGUMENTS = -XX:PermSize=256m -XX:MaxPermSize=512m -Xms1024m -Xmx1024m 
SOA_JAVA_ARGUMENTS = -XX:PermSize=256m -XX:MaxPermSize=752m -Xms1024m -Xmx1532m 
BAM_JAVA_ARGUMENTS = -XX:PermSize=256m -XX:MaxPermSize=512m -Xms1024m -Xmx1532m 
 
 
SOA_REPOS_DBURL = jdbc:oracle:thin:@192.168.xxx.xxx:1521/DBSCHEMA
SOA_REPOS_DBUSER_PREFIX  = QA
SOA_REPOS_DBPASSWORD     = welcome1
 
BPM_ENABLED=false
BAM_ENABLED=true
B2B_ENABLED=true
ESS_ENABLED=true
 
ADMIN_PORT=6001
MANAGED_SOA_PORT=6100
MANAGED_BAM_PORT=6200
MANAGED_OSB_PORT=6300
Note here all properties defined are string values, when port numbers are read from this properties need to convert to integer type using int() funciton. 



Then we need to create the below script create_soa_clustered_doamin.py



loadProperties('clustersoa_osb_domain.properties')
ADM_JAVA_ARGUMENTS = '-XX:PermSize=256m -XX:MaxPermSize=512m -Xms1024m -Xmx1532m -Dweblogic.Stdout='+LOG_FOLDER+'AdminServer.out -Dweblogic.Stderr='+LOG_FOLDER+'AdminServer_err.out'
def createBootPropertiesFile(directoryPath,fileName, username, password):
  serverDir = File(directoryPath)
  bool = serverDir.mkdirs()
  fileNew=open(directoryPath + '/'+fileName, 'w')
  fileNew.write('username=%s\n' % username)
  fileNew.write('password=%s\n' % password)
  fileNew.flush()
  fileNew.close()

def createAdminStartupPropertiesFile(directoryPath, args):
  adminserverDir = File(directoryPath)
  bool = adminserverDir.mkdirs()
  fileNew=open(directoryPath + '/startup.properties', 'w')
  args=args.replace(':','\\:')
  args=args.replace('=','\\=')
  fileNew.write('Arguments=%s\n' % args)
  fileNew.flush()
  fileNew.close()

Run wlst create_soa_clustered_domain.py




Finally you see the below output
