5 WebLogic Server - Introduction #1 in worldwide Application Server Software, with a growth rate of 11.7% The Foundation for Oracle Applications and Middleware Technologies Platform The Foundation for Cloud Applications and Application WebLogic Infrastructure Consolidation Supported features such as Monitoring & Management Scalability/Clustering Virtual Assembly Builder Java EE Standards Enterprise Security Enterprise Messaging Linear Scalability Coherence etc

6 A Quick Poll? How many of you are Business Users How many of you are Technical Users How many of you have actively been using WebLogic Server

7 WebLogic System Administration Top 10 Fundamentals Concepts 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 Middleware Implementations These are the Tips and Tricks

implementing and supporting WebLogic Server platform These are generic

8 #10 Knowing Administration Console Important Elements Tool Bar Appears on top of Console. How do I The Panel includes the context sensitive link to Online Help. Change Center Lock to make any Change in WebLogic Server Domain Structure Admin Console Pages Tree Structure System Status Reports the Health of system

How do I The Panel includes the context sensitive link to Online Help.

9 #9 - WebLogic Domains - Fundamentals!! WebLogic Server administration domain is a logically related group of WebLogic Server resources. Domains include a special WebLogic Server instance called the Administration 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

Domains include a special WebLogic Server instance called the Administration Server, which is the

10 #9 - WebLogic Domain Architecture!! Depending on your particular business needs and system administration practices, you might decide to organize your domains based on criteria such as: Logical divisions of applications Physical location Size

administration practices, you might decide to organize your

11 #8 - Installation of JVM, WLS, etc. Use standard paths between environments DO NOT use Upper and Lower Case Be consistent between the Paths Use Environment variables consistently JAVA_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

Use Environment variables consistently JAVA_HOME, DOMAIN_HOME, etc.

12 #7 Resource Management Mbean Mgmt/SNMP JDBC - Connection pool waiters JDBC - Active Connections Current Count JVM - Heap Size JVM - Garbage Collection JMS ConnectionsCurrentCount JMS MessagesCurrentCount Threads PendingRequestCurrentCount Threads - QueueLength Monitoring file system space, CPU and Memory

JMS ConnectionsCurrentCount JMS MessagesCurrentCount Threads

13 #6 - Thread Dumps for Troubleshoot & Debug WLS Why Take Thread Dumps? - To understand what is actively executed in the system when under load - When system is sluggish or slow or hangs - Java Virtual Process running but Server or App itself not responding - Pages take forever to load - Response time increases - Application and or Server behavior erratic - Just to observe hot spots (frequently executed code) under load - For Performance tuning & for Dependency analysis - To capture snapshot of running state in server

Process running but Server or App itself not responding - Pages take forever to load - Response time increases - Application and

14 #6 - Thread Dumps for Troubleshoot Methods to obtain thread dumps for analysis: - Use WLS Admin Console - Login to AdminConsole >Server > Monitoring > Threads - WLST create.py script - Weblogic.admin (WLS 8.1 and under) - Jrockit JVM java weblogic.admin -url t3://localhost:7001 -username weblogic -password weblogic1 THREAD_DUMP jrcmd PID print_threads - Oracle/Sun Java JVM kill -3 PID - Windows control + break in wls startup cmd script startweblogic.cmd, startmanagedweblogic.cmd - Process Explorer & Debug WLS

admin -url t3://localhost:7001 -username weblogic -password weblogic1 THREAD_DUMP jrcmd PID print_threads - Oracle/Sun Java JVM

15 #6 - Thread Dumps for Troubleshoot & Debug WLS Always take 4 or 5 thread dumps within a sec period Locking States State blocked Description 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) waiting This is the same state as blocked, but with the additional information that the lock in question is a thin lock. This thread has called Object.wait() on an object. The thread will remain there until some other thread sends a notification on that object. sleeping parked suspended This thread has called java.lang.thread.sleep(). This thread has called java.util.concurrent.locks.locksupport.park(). The thread s execution has been suspended by java.lang.thread.suspend() or a JVMTI/JVMPI agent call

blocked (on thin lock) waiting This is the same state as blocked, but with the additional information that the lock in question is a thin lock. This thread has called Object.wait() on an object.

16 #5 Log File Management Consistent log locations across environments Shared file system/folder Leverage log rotation properly and efficiently Tools to view logs WLS Admin Console, EM Console, file system access and 3rd party tools (sawmill for example)

properly and efficiently Tools to view logs WLS Admin Console,

#4 - Back-Up/Restore Server Files Perform a full offline backup shutdown all processes - WLS - Node Managers - Listeners - EM and emagent - OHS - WebCache Perform file system backups using OS tools

17 #4 - Back-Up/Restore Server Files 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

18 #3 - Temporary Files and Cache Management WebLogic creates the temporary files in various temp folders <XYZ>/bea/user_projects/domains/<yourdomain</servers/<yourse rver>/tmp These Cache would often create issues so it would be recommended to delete all files/folders from tmp folders and Restart the server.

<XYZ>/bea/user_projects/domains/<yourdomain</servers/<yourse rver>/tmp These

19 #2 WebLogic Diagnostic Framework (WLDF) Watch & Notification 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 sending notifications based on criteria set in the watches

applications it hosts such as Watches and Notifications - The Watch and Notification component of the WebLogic Diagnostics

20 #2 WebLogic Diagnostic Framework (WLDF) Watch & Notification 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, - Simple Network Management Protocol (SNMP) - Diagnostic Images

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
