1) Starting and Stopping a
Managed Server
As a best
practice, it is always recommended that you start and stop a managed server
through one, but not both, of the following methods. Do not mix these
methods, such as starting the managed server from the command line and stopping
it from Oracle Enterprise Manager Fusion Middleware Control, or vice versa.
- Oracle Enterprise Manager
Fusion Middleware Control
With this method, the node manager
must be up and running. The node manager tracks all managed server startups and
shutdowns performed from Oracle Enterprise Manager Fusion Middleware Control.
With this method, the server state is not an issue.
With this method, the node manager does
not track the server state. Therefore, if you start the server from the command
line and shut it down from Oracle Enterprise Manager Fusion Middleware Control,
the Oracle WebLogic Administration Server accesses the node manager to
determine its status, which returns a state of Unknown.
Perform the following steps to stop and start the server
from Oracle Enterprise Manager Fusion Middleware Control.
- Expand the WebLogic domain.
- Select the managed server (for
example, named soa_server1).
- Select Control
--> Shut Down.
- Select Control
--> Start Up

The intent of this note is to list the important
configuration and log files used to diagnose SOA 11g problems.
Throughout this note we will refer to the following:
- $ MIDDLEWARE_HOME =
- $ DOMAIN_HOME = $
MIDDLEWARE_HOME/user_projects/domains/
Here is a list of files to look for:
1.Domain configuration under $DOMAIN_HOME/config directory
- Config.xml
- jdbc/-Jdbc.xml
- jms/-Jms.xml files under
2. Adapter configuration under $MIDDLEWARE_HOME//soa/connectors/
directory. ( Oracle_SOA1 is the default name)
- AppsAdapter.rar
- DbAdapter.rar
- FtpAdapter.rar
- MQSeriesAdapter.rar
- SocketAdapter.rar
- AqAdapter.rar
- FileAdapter.rar
- JmsAdapter.rar
- OracleBamAdapter.rar
Issue:
while creating new domain in step
select domain source I am getting "CFGFWK-64069 prerequisite missing:
Oracle WSM Policy Manager 11.1.1.0 Oracle BI Composer Runtime , oracle BI-ADF runtime
11.1.1.0
Solution:
This could be because of higher
security in windows vista/windows 7
Check file permission and owner of
MW_HOME and subdirectory (reset permission of MW_HOME directory and
subdirectory) .
If you are creating domain using command
line config.cmd then start command promt in administrative mode and then try.
