nsjspadmin.config ServerClass Configuration File
Stop button. The Ignore button allows these inconsistent servers to continue to run.
The operator should stop these processes manually.
All occurrences of inconsistency are logged to the associated Logger objects. When a
servlet server process catches an exception while processing an admin command, the
servlet server process automatically stops itself. The warning page lists those servlet
server processes that exit by themselves. However, if an exception is caught before
the admin web application processes the admin request, the exception is returned to
the nsjspadmin ServerClass. The warning page lists the server process names and
allows the operator to stop them.
If instructed to stop the inconsistent servers, nsjspadmin first chooses a graceful stop
method which allows the inconsistent servers to flush all their session information
before they are stopped. If this graceful stop method fails to stop any of the
inconsistent servers, a forced stop method is used. Depending on the flush of session
information, you may experience servers lingering for a while since the response to
your stop command is returned before the inconsistent servers are actually stopped.
nsjspadmin.config ServerClass Configuration File
The nsjspadmin.config file is created for the configuration of the nsjspadmin
ServerClass. Although the nsjspadmin ServerClass is in the same TS/MP
environment as the SERVLET ServerClass, it still has its own configuration file to
prevent the attributes of the nsjspadmin ServerClass from being changed
accidentally. Most of these attributes should be maintained as the installed value.
For detailed information about configuirng the nsjspadmin.config file, see
nsjspadmin.config on page 3-5.
nsjspadmin.ssc
A symbolic link named nsjspadmin.ssc is added to the bin directory of the iTP
WebServer installation. (The same location where servlet.ssc resides)
servlet ServerClass Restrictions
The nsjspadmin ServerClass handles admin-related requests. Any attempts to
access admin and manager web applications from the SERVLET ServerClass directly
are rejected with error 503: Service Unavailable.
Access Security Considerations
If the online administration (configuration and management) option is not selected at
setup time, then no user with the admin or manager role is added to the
$NSJSP_HOME/conf/nsjspadmin-users.xml configuration file. In order to access
the admin and manager web application, you will need to add users with these roles
manually.
