Enabling application isolation 79
To configure multiple server instances for application isolation when using Apache:
1 Run the Web Server Configuration Tool once, specifying the location of the Apache httpd.conf
file and any other required information.
2 The Web Server Configuration Tool creates a sequentially numbered subdirectory under
jrun_root/lib/wsconfig. You can use the subdirectory created by the Web Server Configuration
Tool for one of your virtual hosts but you must create additional subdirectories for all other
virtual hosts. For example, the first time you run the Web Server Configuration Tool, it creates
jrun_root/lib/wsconfig/1; if you have two other virtual hosts, you must manually create two
other directories, jrun_root/lib/wsconfig/mystore and jrun_root/lib/wsconfig/myemp
directories. These directories can be empty.
3 Open the jrun_root/servers/servername/SERVER-INF/jrun.xml file for each of your server
instances, ensure that the
deactivated element is set to false, and note the value of the port
element for the ProxyService service. For example:
...
<service class="jrun.servlet.jrpp.JRunProxyService" name="ProxyService">
<attribute name="activeHandlerThreads">25</attribute>
<attribute name="backlog">500</attribute>
<attribute name="deactivated">false</attribute>
<attribute name="interface">*</attribute>
<attribute name="maxHandlerThreads">1000</attribute>
<attribute name="minHandlerThreads">1</attribute>
<attribute name="port">51002</attribute>
...
4 Open the apache_root/conf/httpd.conf file in a text edit and find the VirtualHost directives.
The settings added by the Web Server Configuration Tool are after the last
</IfModule>
directive, as the following example shows:
...
# JRun Settings
LoadModule jrun_module "C:/JRun4/lib/wsconfig/1/mod_jrun20.so"
<IfModule mod_jrun20.c>
JRunConfig Verbose false
JRunConfig Apialloc false
JRunConfig Ssl false
JRunConfig Ignoresuffixmap false
JRunConfig Serverstore "C:/JRun4/lib/wsconfig/1/jrunserver.store"
JRunConfig Bootstrap 127.0.0.1:51020
#JRunConfig Errorurl <optionally redirect to this URL on errors>
