2 服务器管理

可使用 STA 命令管理和检查各种 STA 组件的状态。STA 命令变量分为两类：

• 用于启动或关闭整个 STA 环境或者检查整个 STA 环境的状态的命令

• 启动或关闭单个 STA 服务或检查单个 STA 服务的状态的命令。

注意: 单个 STA 服务命令仅供参考。不要执行这些命令，除非受到 Oracle 技术支持人员的指示。

可以随时使用命令 STA help 获得有效 STA 命令参数列表。

• "受管服务器."

• "内存使用要求."

• "全局管理命令."

• "单个服务管理命令."

2.1 受管服务器

各种 STA 进程分入以下三个受管服务器：

• staUi－STA 用户界面

• staEngine－基本 STA 内部函数

• staAdapter－SNMP 通信

受管服务器可以单独进行管理。请参见"单个服务管理命令."

2.2 内存使用要求

表 2-1 显示了 STA 域服务器、STA 受管服务器和 MySQL 的内存使用要求。

表 2-1 内存使用要求

项	内存需求
STA 域服务器	2 GB 堆大小
STA 受管服务器	2 GB 堆大小
MySQL	2 GB 内存

2.3 全局管理命令

以下 STA 命令可用于启动和停止整个 STA 环境以及检查整个 STA 环境的状态。

• STA start all

  启动整个 STA 环境。

  # STA start all
  Starting mysql Service..
  mysql service was successfully started
  Starting staservd Service.
  staservd service was successfully started
  Starting weblogic Service......
  weblogic service was successfully started
  Starting staengine Service.........
  staengine service was successfully started
  Starting staadapter Service..........
  staadapter service was successfully started
  Starting staui Service..........
  staui service was successfully started
  

• STA stop all

  停止整个 STA 环境。

  # STA stop all
  Stopping the staui service......
  Successfully stopped the staui service
  Stopping the staadapter service......
  Successfully stopped the staadapter service
  Stopping the staengine service......
  Successfully stopped the staengine service
  Stopping the weblogic service......
  Successfully stopped the weblogic service
  Stopping the staservd Service...
  Successfully stopped staservd service
  Stopping the mysql service.....
  Successfully stopped mysql service
  

• STA status all

  显示整个 STA 环境的状态。

  # STA status all
  mysql service is running
  staservd service is running
  weblogic service is running
  staengine service is running
   .... and the deployed application for staengine is in an ACTIVE state
  staadapter service is running
   .... and the deployed application for staadapter is in an ACTIVE state
  staui service is running
   .... and the deployed application for staui is in an ACTIVE state
  

2.4 单个服务管理命令

以下 STA 命令可用于启动和停止单个 STA 组件或检查这些组件的状态。

注意: 单个 STA 服务命令仅供参考。不要执行这些命令，除非受到 Oracle 技术支持人员的指示。

• STA start|stop|status mysql

  启动或停止 MySQL，或显示其状态。

• STA start|stop|status staservd

  启动或停止 STA 服务守护进程，或显示其状态。

• STA start|stop|status weblogic

  启动或停止 WebLogic AdminServer，或显示其状态。

• STA start|stop|status staadapter

  启动或停止 staAdapter 受管服务器，或显示其状态。

• STA start|stop|status staengine

  启动或停止 staEngine 受管服务器，或显示其状态。

• STA start|stop|status staui

  启动或停止 staUi 受管服务器，或显示其状态。
