Problem: No list of Unwired Servers displays in Sybase Control Center. Instead, an Error Retrieving Server List message appears in the left navigation pane.
Scenario 1: No other error message appears.
If this is the case, one of the following explanations may apply:
- You are attempting to connect to a remote server that is not properly registered in Sybase Control Center.
Solution: Manually register the remote server. By default, only Unwired Servers installed to the same host computer are automatically registered with Sybase Control Center. See Sybase Control Center > Get Started > Getting Started with Unwired Platform Administration
> Getting Started with Remote Server Administration. If you have recently made changes to the environment, for example, by modifying server resource properties (login, password, host name, IP address, or port number), ensure that you reauthenticate after making the changes.
- Jetty caching in Sybase Control Center prevents the console from displaying the server tree. This is indicated by 404 errors in both the console URL and <UnwiredPlatform_InstallDir>\SCC-XX\services\EmbeddedWebContainer\log\http-service.log (the HTTP access log).
Solution:
- Close Sybase Control Center.
- Stop Sybase Unified Agent Service.
- Delete the contents of: <UnwiredPlatform_InstallDir>\SCC-XX\services\EmbeddedWebContainer\container\Jetty-6.1.6\work.
- Restart Sybase Unified Agent Service.
Scenario 2: The right administration pane shows an Authentication has failed error message.
If this is the case, one of the following explanations may apply:
- The security repository (LDAP server) is down or not reachable. In the default configuration (excluding the Deployment Edition), the security repository is the OpenDS LDAP server.
Solution: Check the status of the security repository to ensure that the server is reachable. For the OpenDS LDAP server, check the Services in the Windows Control Panel to ensure that the service is running and that the server is reachable from Sybase Control Center and the Unwired Server host.
- You have not performed the "Authenticate" step in Sybase Control Center after registering the resource or changing their credentials.
Solution: In the Perspective Resources view, right click the server name and select Authenticate. In the default configuration, if you have used "supAdmin" to log in to Sybase Control Center, select Use my current SCC login.
- You do not have the required administration privileges.
Solution: Ensure that:
- The administrator login is assigned one of the physical roles attached to the "SUP Administrator" or "SUP Domain Administrator" logical roles in the "admin" security configuration. To change the "admin" role mapping outside of Sybase Control Center, manually edit <UnwiredPlatform_InstallDir>\UnwiredPlatform\Servers\UnwiredServer\Repository\CSI\conf\role-mapping.xml on all nodes in the cluster.
- The <UnwiredPlatform_InstallDir>\SCC-XX\conf\roles-map.xml configuration for the "SUP LDAP Login Module" and your security repository are being used to authenticate Sybase Control Center users. Ensure that the administration roles configured for the "SUP LDAP Login Module" exist in the security repository.
- The server IP may have changed.
Solution: Update server resource properties, and repeat the "Authenticate" step described above. See the topic Sybase Control Center Fails to Start.
Scenario 3: The right administration pane shows a Connection unknown. Ensure Server is running.... message.
If this is the case, one of the following explanations may apply:
- Unwired Server responded with an exception indicating a problem on the server.
Solution: Check <UnwiredPlatform_InstallDir>\UnwiredPlatform\Servers\UnwiredServer\logs\<hostname>-server.log for details.
- The Sybase Control Center security provider is down or a system condition prevents Sybase Control Center from authenticating the user for administration access.
Solution: Ensure that the security provider is running and that its host is reachable from the Sybase Control Center host.
