Problem: After you have registered a remote server in
Sybase Control Center, you cannot start or restart the
server.
If the DNS server cannot resolve the host name of the machine on
which the remote Unwired Server is installed, or if the host has
no internal DNS server, you cannot start, stop, or restart that
Unwired Server using your local instance of
Sybase Control Center. Because this network communication
relies on name resolution, you must ensure that DNS is set up properly to
successfully control a remote Unwired Server.
Before attempting the following solutions, verify that:
- Sybase Control Center is running on the remote host.
- A network connection can be established between your
Sybase Control Center host and the
Sybase Control Center agent on the remote server's
host.
If the DNS server cannot establish a connection, try the following:
Solution 1: Repair the network DNS server setup. If you or your network administrator cannot modify the DNS, use solution 2.
Solution 2: Change the host name to its IP address in the
Sybase Control Center
service-config.xml file:
- If you cannot resolve the local host name, modify the file
on the local instance of Sybase Control Center.
- If you cannot resolve the remote host name, modify the file
on the remote instance of Sybase Control Center.
- If you cannot resolve both the remote and local host names, modify both files.
- From the command line, verify the host name by running
nslookup<hostname
>.
- If the DNS server cannot resolve the host name, edit the collocated
SCC_HOME\services\RMI\service-config.xml file:
- Log out of Sybase Control Center.
- Stop the Sybase Control Center X.X
service.
- Open
SCC_HOME\services\RMI\service-config.xml.
- Locate this line: <set-property
property="address" value="<hostname>" />.
If the
line does not exist, add it under the
<properties></properties> element in
the file.
- Change the value from the host name to the IP address of the
host computer. If the IP address is already used, ensure it is valid
(especially if the IP address has recently been changed).
- Restart the Sybase Control Center X.X
service.
- Log in to Sybase Control Center and
proceed with your administrative tasks.
If the DNS server resolves the host name, but the problem persists, check that both:
- The remote host on which Unwired Platform and
Sybase Control Center are installed can receive UDP
multicasts from the local host on which
Sybase Control Center is installed, and
- The remote instance of
Sybase Control Center uses RMI port 9999.
