+課程介紹： ???? 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: ???????
