Set Managed Server Log Rotation Using WebLogic Scripting Tool (WLST)

WebLogic Scripting Tool (WLST) provides a command line scripting interface to manage WebLogic Server instances and domains. This article gives an example of setting the log rotation of a managed server using WebLogic Scripting Tool (WLST). You will need to adjust the values in the properties file and may wish to alter the script to suit your needs.

Script

Create a file called "set_ms_log_rotation.py" with the following contents.

#!/usr/bin/python
# Author : Tim Hall
# Save Script as : set_ms_log_rotation.py

import time
import getopt
import sys
import re

# Get location of the properties file.
properties = ''
try:
   opts, args = getopt.getopt(sys.argv[1:],"p:h::",["properies="])
except getopt.GetoptError:
   print 'create_managed_server.py -p <path-to-properties-file>'
   sys.exit(2)
for opt, arg in opts:
   if opt == '-h':
      print 'create_managed_server.py -p <path-to-properties-file>'
      sys.exit()
   elif opt in ("-p", "--properties"):
      properties = arg
print 'properties=', properties

# Load the properties from the properties file.
from java.io import FileInputStream
 
propInputStream = FileInputStream(properties)
configProps = Properties()
configProps.load(propInputStream)

# Set all variables from values in properties file.
adminUsername=configProps.get("admin.username")
adminPassword=configProps.get("admin.password")
adminURL=configProps.get("admin.url")
msName=configProps.get("ms.name")

# Display the variable values.
print 'adminUsername=', adminUsername
print 'adminPassword=', adminPassword
print 'adminURL=', adminURL
print 'msName=', msName

# Connect to the AdminServer.
connect(adminUsername, adminPassword, adminURL)

edit()
startEdit()

# Manage logging.
cd('/Servers/' + msName + '/Log/' + msName)
cmo.setRotationType('byTime')
cmo.setFileCount(30)
cmo.setRedirectStderrToServerLogEnabled(true)
cmo.setRedirectStdoutToServerLogEnabled(true)
cmo.setMemoryBufferSeverity('Debug')
cmo.setLogFileSeverity('Notice')

save()
activate()

disconnect()
exit()

Properties

Create a file called "myDomain-ms1.properties" with the following contents.

# AdminServer connection details.
admin.username=weblogic
admin.password=Password1
admin.url=t3://ol6.localdomain:7001

ms.name=myServer_1

Run It

Create the new domain using the following commands.

# Set environment.
export MW_HOME=/u01/app/oracle/middleware
export WLS_HOME=$MW_HOME/wlserver_10.3
export WL_HOME=$WLS_HOME
export JAVA_HOME=/u01/app/oracle/jdk1.7.0_79
export PATH=$JAVA_HOME/bin:$PATH
export CONFIG_JVM_ARGS=-Djava.security.egd=file:/dev/./urandom

. $WLS_HOME/server/bin/setWLSEnv.sh

# Create the domain.
java weblogic.WLST set_ms_log_rotation.py -p myDomain-ms1.properties
