Concurrent Manager


Internal Concurrent Manager (ICM)

ICM实际上是一个后台进程，用于管理其他Manager(start/stop).DBA要保证ICM处于运行状态，否则其他的Concurrent Manager无法Start/Stop.



Standard Manager (SM)

默认的concurrent manager，如果request没有指定具体的Concurrent Manager(比如Inventory Manager, Receivables Tax Manager, etc)，那么SM就会作为默认的Mananger来处理这个request。



产品相关的Concurrent Manager
有很多产品相关的Concurrent Managers.比如Inventory Manager, MRP Manager,Receiving Transaction Manager. 这些Managers针对特定模块来构建的，用于统一管理特定模块的program。

Concurrent manager和concurrent programs

Concurrent manager manages the concurrent parallel execution of concurrent programs.You can determine when a manager runs and how many programs a manager can start simultaneously.

A Concurrent Request is the ‘worker’ that gets scheduled and controlled by Concurrent Managers.

系统里检查ICM Concurrent Manager是否处于运行状态

检查方法 System Administrator responsibility ， concurrent > manager > administer > Internal Manager,如果Processes下面，Target等于Actual,并且大于0，这就意味着manager是启动的。


操作系统下如何检查Concurrent Mananger的运行情况

FNDLIBR进程是否启动 ，这个表示ICM进程是否运行

System Admin > Concurrent > Manager > Defien

ps -ef | grep FNDLIBR

FNDLIBR process indicates that concurrent mnagers are up and requests are running on the system.Sometimes it happens that even after stopping the concurrent managers by adcmctl.sh stop apps/apps some of the requests might continue running. In such cases you can wait for say 5 minutes and then if it dos not stop then you can kill those FNDLIBR processes bykill -9 <processid>

其他Concurrent Manager Processes

INVLIBR is the process for the following Managers
Manager to run Immediate Concurrent Programs defined in INVLIBR
