Oracle Process Management Network (OPMN)

Oracle Process Management Network (OPMN)

OPMN is a process management tool which manages all system components((non JEE applications). It is also supports both local and distributed process management, automatic process recycling and the communication of process start like starting, stopping etc., OPMN detects process unavailability and automatically restarts processes.

OPMN can be managed using FMW Control or using Command prompt.

Using Fusion Middleware Control:

Log in to FMW Control Enterprise Manager (e.g. http://localhost:7001/em)

Navigate to BusinessIntelligence > coreapplication > Capacity Management tab> Availability tab

In this windows you can see the status of all 5 system components. You can start, stop or restart any selected process or all processes using the buttons.

Using Command Prompt:

In the command prompt navigate to \instances\instance_number\bin\ (e.g. C:\OBI\instances\instance2\bin\), then execute the following commands as per your requirement.

To Start all OPMN processes: opmnctl startall

To Stop all OPMN processes: opmnctl stopall

To see the status of all system components: opmnctl status

startproc, stopproc, restartproc are the commands to start or stop individual processes. Here is the example to start all 5 System components individually.

BI Cluster Control: opmnctl startproc ias-component=coreapplication_obiccs1

BI Scheduler: opmnctl startproc ias-component=coreapplication_obisch1

BI Java Host: opmnctl startproc ias-component=coreapplication_obijh1

BI Presentation Services: opmnctl startproc ias-component=coreapplication_obips1

BI Server: opmnctl startproc ias-component=coreapplication_obis1
