+课程介绍：      WebLogic Server offers a seemingly endless list of capabilities for hosting enterprise services and applications. However, with this complexity come opportunities for problems, both while testing and in production. Luckily, WebLogic Server includes a wealth of tools to help monitor, profile and troubleshoot its various subsystems. The WebLogic Diagnostics Framework (WLDF), the WebLogic Scripting Tool (WLST) and JRockit Mission Control are three such tools.      This course helps experienced Oracle WebLogic Server administrators identify typical problems and trains them on the appropriate methodology and tools for solving each problem. As part of this process, students gain a rich knowledge of WebLogic's internal subsystems, including work managers, JDBC, JMS, security, SSL and clusters.      An appendix is included covering the differences between the 11g (10.3.3) and 12c (12.1.1) product versions with regard to Oracle WebLogic Server administration topics.         Learn to:         Develop custom scripts to monitor servers         Use the capabilities of the WebLogic diagnostics framework         Interpret log messages for WebLogic subsystems         Monitor and analyze virtual machine statistics         Troubleshoot security and cluster issues         Troubleshoot JDBC and JMS problems 课程对象：         Administrator         Java EE Developer         Security Administrators         Support Engineer         Technical Administrator         Web Administrator 课程大纲：         WLST Monitoring                 MBean Hierarchies                 Jython Syntax                 WLST Commands         Guardian                 Agents                 Signatures                 Evaluations         Diagnostic Framework Essentials                 Diagnostic Images                 Diagnostic Archives                 Metric Collectors                 Watches                 Notifications                 Console Extension                 Debug Scopes         Diagnostic Instrumentation                 Monitors                 Actions                 Deployment Plans                 Pointcuts                 Request Tracking                 Context ID                 Dyes         JVM Diagnostics                 Memory Management                 Garbage Collection                 Memory Leaks                 Thread Dumps                 JVisualVM                 JRockit Mission Control                 Runtime Analyzer                 Memory Leak Detector         Troubleshooting Java Applications                 Classpath Errors                 Class Loaders                 Common Java Errors         Troubleshooting Servers                 Native Libraries                 Threading Architecture                 Work Managers                 Deadlocks                 Overload Protection                 Deployment Problems         Troubleshooting JDBC                 Data Source Management                 Diagnostics                 Debug Flags                 Connectivity Problems                 Connection Leaks                 Database Availability         Troubleshooting JMS                 Management                 MBean Hierarchy                 Message Logging                 Diagnostics                 Debug Flags                 Overload Protection                 Lost Messages                 Duplicate Messages         Troubleshooting Security                 SSL Internals                 Keystore Management                 Debug Flags                 Common SSL Problems                 Certificate Validation                 Embedded LDAP                 Security Audit                 Common LDAP Problems         Troubleshooting Node Manager                 Internals                 Security                 Common Issues         Troubleshooting Clusters                 Plug-in Configuration                 OHS Overview                 Plug-in Connectivity                 Plug-in Diagnostics                 Unicast Communication                 Replication Debug Flags                 Typical Replication Issues
