Discovery component specific MustGather information
In the administrative console under System Administration >
Nodes, the node in question has a status of Unknown, or it
is using wsadmin and is not able to get the $AdminControl MBean
object for the nodeagent. However, the nodeagent and the Deployment
Manager are running.
The nodeagent and Deployment Manager must discover each other to have
synchronization and administrative commands work properly on the base
node. There are multiple reasons why the nodeagent and the Deployment
Manager might not be able to talk to each other correctly.
- Tracing the discovery process on the nodeagent and dmgr:
- Stop all Application Server processes (no Java processes).
- Modify the server.xml files for both nodeagent and dmgr:
- Enable discovery tracing on the dmgr:
- Edit the server.xml file for the dmgr located in the
following directory:
ND_PROFILE/config/cells/cellname/nodes/nodename/servers/dmgr |
|
- Find the TraceService XML tag section.
- Modify the startupTraceSpecification entry to look like the
following:
- For V5.0 and V5.1:
com.ibm.ws.management.*=all=enabled |
|
- For V6.0 and V6.1:
com.ibm.ws.management.*=all |
|
- Make sure enable is set to true.
- Enable discovery tracing on the nodeagent:
- Edit the server.xml file for the nodeagent located in the
following directory:
BASE_PROFILE/config/cells/cellname/nodes/nodename/servers/nodeagent |
|
- Find the TraceService XML tag section.
- Modify the startupTraceSpecification entry to look like the
following:
- For V5.0 and V5.1:
com.ibm.ws.management.*=all=enabled |
|
- For V6.0 and V6.1:
com.ibm.ws.management.*=all |
|
- Make sure enable is set to true.
- Clear all the files in the following directories:
- For V5.0 and V5.1:
- For V6.0 and V6.1:
BASE_PROFILE/logs |
|
and |
|
ND_PROFILE/logs |
|
- Issue the following command:
- Start the nodeagent and dmgr.
- Open the administrative console and navigate to System
administration > Nodes to see if the node is still has a
status of Unknown.
- Issue the following command:
- Stop the nodeagent and dmgr.
- Run the collector tool on both Network Deployment and base.
- Follow directions in MustGather: Read first to open a PMR and send data to
IBM® Support.
