对adRegisterWLSListeners.pl 和 adSyncContext.pl 脚本的研究


事情起源与在应用层发现一个进程：

[apptest@vs022 bin]$ ps -fu apptest|grep opmn

根据进程20274查找到了父进程：

[apptest@vs022 bin]$ ps -fu apptest|grep 20274

apptest  28629 27833  0 23:40 pts/2    00:00:00 grep 20274

查看了此脚本产生的日志如下：

经过从网上查询，确定了这是一个监听weblogic参数配置变化的进程，这个进程会跟随weblogic 中的Admin server一同启动和关闭：

Run adRegisterWLSListeners Tool on the Application Tier

  • The adRegisterWLSListeners tool has been introduced to perform synchronization of context variables with the associated Oracle WebLogic Server configuration parameters.
  • This tool does not listen for changes to the Oracle HTTP Server configuration parameters.
  • Once started, adRegisterWLSListeners keeps running, listening for changes to the WebLogic Server configuration and synchronizing the context files stored in the database.
  • This tools starts/stops along with the WebLogic Admin Server.

Scenario on adRegisterWLSListeners


Run SyncContext on the Application Tier

  • The adSyncContext.pl script reads the WLS configuration parameter values and synchronizes them with the context variables.
  • This is used to synchronize the OHS configuration parameters with the respective context variables.
  • This mechanism is called the 'feedback loop‘
  • The SyncContext tool is one of the tools used for explicit synchronization of the context variables with the WLS configuration parameters.
  • In Oracle E-Business Suite Release 12.2 some important configuration files like httpd.conf and ssl.conf  are no longer maintained by AutoConfig. Oracle Enterprise Manager 11g Fusion Middleware Control should
    be used to maintain these configuration files as well as making additional changes to Context File variables.
