Grid Control major components:OMA、OMS and OMR
Grid Control major components:OMA、OMS and OMR
The Grid Control framework includes:
● Oracle Management Repository (OMR)
● One or more Oracle Management Service (OMS)
● One or more Oracle Management Agent (OMA)
GC 不仅可以管理任何主流的 Oracle 产品、而且还能侦测自定义(比如:路由器)的目标
OMAs 收集目标的信息(比如:可用性、配置和性能)、然后把这些信息传递给 OMS
一个 OMA 只和一个 OMS 对话、但一个 OMS 能服务多个 OMA
接着、OMS 把所接收的信息再抄送一份给 OMR
一个 OMS 只和一个 OMR 对话、然而一个 OMR 可服务多个 OMS
㈠ Oracle Management Agent
The OMA is responsible for :
① all active monitoring
② communication between Grid Control and all managed targets.
The OMA:
● Must be installed on each host server
A single management agent inte易做图ces the OMS with all managed targets on the host server
● Must be in its own ORACLE_HOME
Management agents are installed in their own ORACLE_HOME、and
controlled with the emctl utility
● Communicates with the OMS via HTTP or HTTPS
㈡ Oracle Management Service
The OMS is responsible for :
① renders the user inte易做图ce for Grid Control, works with all OMAs
② stores persistent data in the OMR
The OMS:
● Includes member components:
Ⅰ Oracle HTTP Server (OHS)
Ⅱ Oracle Application Server Containers for J2EE (OC4J)
Ⅲ OracleAS Web Cache
● Is a J2EE application deployed on Oracle Application Server 10g
● Connects to the OMR by using JDBC
You can connect to the GC via a Web browser through OHS and OracleAS Web Cache:
① OracleAS Web Cache is configured to listen for DBA's connections on port 7777
and pass the connection through to the OHS on port 7778
② OMAs connect to the application directly throughOHS, bypassing OracleAS Web Cache
In most installations, OHS listens for OMA traffic on port 4889
㈢ Oracle Management Repository
The OMR is responsible for :
① organizes the data receiving from OMS so it can be retrieved by OMS and displayed on GC
The OMR:
● Resides in an Oracle database
● Includes schema objects belonging to SYSMAN
The OMR is installed in an Oracle database as a group of approximately 4,000 schema objects
These schema objects contain information about:
GC administrators, targets, and applications that are managed by GC
● Can be installed in a preexisting database
The OMR may be installed either in its own private database orin an existing database
