我来说一句

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 > Define

其他Concurrent Manager Processes

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

[oracle@bej301441 ~]$ ps -ef | grep INVLIBR
oracle    7111  7004  0 Jul03 ?        00:00:07 INVLIBR                                                                                               
oracle   14016 13573  0 19:40 pts/5    00:00:00 grep INVLIBR
[oracle@bej301441 ~]$

MRCLIB is the process for the following Managers
MRP Manager

[oracle@bej301441 ~]$ ps -ef | grep MRCLIB
oracle    7113  7004  0 Jul03 ?        00:00:06 MRCLIB                                                                                                
oracle   14024 13573  0 19:40 pts/5    00:00:00 grep MRCLIB
[oracle@bej301441 ~]$

PALIBR is the process for the following Managers
PA Streamline Manager

如何start/stop ICM

$COMMON_TOP/admin/scripts for 11i 

$INST_TOP/admin/scripts for R12

[oracle@appsnode log]$ adcmctl.sh  stop apps/apps
You are running adcmctl.sh version 120.17.12010000.5

oracle    7931  7759  0 06:55 ?        00:00:00 FNDLIBR

ICM log file?

ICM log文件位于$APPLCSF/$APPLLOG或者$FND_TOP/$APPLLOG.
ICM日志的格式：<SID>_MMDD.mgr
