These are the concepts for WebLogic Server Administration

based on our experience in implementing and supporting

WebLogic Server platform

These are generic concepts that would apply in any Oracle

WebLogic Server administration domain is a logically related groupof WebLogic Server resources.

Domains include a special WebLogic Server instance called theAdministration Server, which is the central point from which you

configure and manage all resources in the domain. Contents of a Domain

Administration Server

Managed Servers

Resource Services

#9 - WebLogic Domains - Fundamentals!!


10/24

Depending on your particular

business needs and system

administration practices, you

might decide to organize yourdomains based on criteria such

as:

Logical divisions of applications

Physical location

Size

#9 - WebLogic Domain Architecture!!


11/24

DO NOT use Upper and Lower Case

Be consistent between the Paths

Use Environment variables consistentlyJAVA_HOME,DOMAIN_HOME, etc.

Check for port conflicts before installing and configuring domain

Use JRocket as JVM and tune your JVM as per you Application

requirements

Consistent log file configurations and proper log rotation sequence

#8 - Installation of JVM, WLS, etc. Use

standard paths between environments

14/24

Methods to obtain thread dumps for analysis:

- Use WLS Admin Console - Login to AdminConsole>Server >

Monitoring > Threads

- WLSTcreate .py script- Weblogic.admin (WLS 8.1 and under)

java weblogic.Admin -url t3://localhost:7001 -username weblogic -password weblogic1 THREAD_DUMP

- Jrockit JVM

jrcmd PID print_threads- Oracle/Sun Java JVM

kill -3 PID

- Windowscontrol + break in wls startup cmd scriptstartweblogic.cmd,

startmanagedweblogic.cmd

- Process Explorer

#6 - Thread Dumps for Troubleshoot

& Debug WLS


15/24

Always take 4 or 5 thread dumps within a 20-25 sec period

Locking States

State Description

blocked This thread has tried to enter a synchronized block, but the lock was taken by another thread.This thread is blocked until the lock gets released.

blocked (on thin lock) This is the same state as blocked, but with the additional information that the lock in questionis a thin lock.

waiting This thread has called Object.wait() on an object. The thread will remain there until some otherthread sends a notification on that object.

sleeping This thread has called java.lang.Thread.sleep().

parked This thread has called java.util.concurrent.locks.LockSupport.park().

suspended The threads execution has been suspended byjava.lang.Thread.suspend() or aJVMTI/JVMPI agent call

#6 - Thread Dumps for Troubleshoot

& Debug WLS


16/24

Consistent log locations across environments

Shared file system/folder

Leverage log rotation properly and efficiently

Tools to view logsWLS Admin Console , EM Console, file system

access and 3rd party tools (sawmill for example)

#5 Log File Management


17/24

Perform a full offline backup shutdown all processes- WLS

- Node Managers

- Listeners

- EM and emAgent

- OHS

- WebCache

Perform file system backups using OS tools such as tar: tar -zcvpf backup1.tar ...

Test backup by performing recovery on another computer Configure automatic backup of WLS configuration it will create

config-booted.xml and config-original.xml

#4 - Back-Up/Restore Server Files

WebLogic creates the temporary files in various temp folders

WebLogic Diagnostics Framework (WLDF) consists of a number of

components that work together to collect, archive, and access

diagnostic information about a WLS Server instance & the

applications it hosts such as

Watches and Notifications - The Watch and Notification component

of the WebLogic Diagnostics Framework (WLDF) provides the means

for monitoring server and application states and then sendingnotifications based on criteria set in the watches

#2 WebLogic Diagnostic Framework

(WLDF)

Watch & Notification


20/24

A Watch identifies a situation that you want to trap for monitoring or

diagnostic purposes & can be configured to analyze log records, data

and events. A watch is specified as a watch rule, which includes:

- A watch rule expression

- An alarm setting

- One or more notification handlers

A notification is an action that is taken when a watch rule expression

evaluates to true. WLDF supports the following types of notifications:

- Java Management Extensions (JMX)- Java Message Service (JMS)

- Simple Mail Transfer Protocol (SMTP), for example, e-mail

- Simple Network Management Protocol (SNMP)

- Diagnostic Images
