WS Plug-in Configuration Tool
AUTO_LOAD
set this to ON to enable automatic detection of configuration database updates.
The WS Plug-in processes read the configuration database at startup and build an
internal list of URL prefixes and the cluster to which requests should be sent. The
iTP WebServer sends all requests it cannot process to the WS Plug-in. If the prefix
is not in the WS Plug-in's list, it will generate an EMS message and reject the
request. However, if this option is turned on, iTP WebServer will first check to see
if the configuration database tables have been updated since the process last read
them. If so, it will reload the configuration data and try to find the requested prefix
in the new internal list. Note that setting the auto load option will not cause existing
WS Plug-in processes to detect changes to previously configured prefixes, that is,
if you add a server to a cluster or direct a previously configured prefix to be routed
to a different cluster. This scenario can be dealt with by forcing the WS Plug-in
processes to reload the current configuration from the database tables - see
Modifying the Database for details.
The default is OFF, which means the WS Plug-in does not check for recent
modification of the configuration database tables. In this case, you need to use the
make utility to force the WS Plug-in processes to reload the current configuration
from the database tables - see Modifying the Database for details.
DISPLAY_CONFIG
The WS Plug-in includes the facility to view the current configuration using a Web
Browser. For security reasons the default is OFF. Set this option to ON to enable
this facility. To view the configuration, enter the '_PluginConfig' URL. Note there
are a number of iTP WebServer directives that can be used to restrict access to
the Configuration Display. See the iTP Secure WebServer System Administrator's
Guide for information.
WS Plug-in Configuration Tool
The WS Plug-in Configuration Tool for WebLogic Server uses the WebLogic Server
configuration file (config.xml) and user-provided input to add entries to the WS
Plug-in's SQL/MP database script file (dbload.sqlci). You can then use the make
utility to update the database and signal the active WS Plug-in processes to reload the
new configuration, see Modifying the Database
below.
The configuration tool is run using the plugin-config.sh shell script located in
iTP WebServer directory/bin/rmt. You can run this script from any directory.
Write access is required to the iTP WebServer directory/bin/rmt directory and
the dbload.sqlci contained in that directory. Only one user can run the utility at any
one time.
