Valid ArcSDE services can be monitored by the ArcSDE Services Monitor. If the ArcSDE Services Monitor was selected to be installed, the ArcSDE Services Monitor Configuration will be available as a post installation setup option.
Provide Application Server Host Name, and Registry Port.
Enter the name of the machine where the Application Server is installed. Your machine name is provided as your Application Server host name by default. To find the host name of your machine, open a Command Prompt and type hostname. The Registry Port default is 5353. The ArcIMS Spatial Server, Monitor, and Tasker communicate with the ArcIMS Application Server via the Registry port.
Provide user name and password for ArcIMS services authorization.
The user name and password is required to start the ArcIMS Monitor service. The user name should include the domain and the user name of the ArcIMS installation account, for example, esri\ArcIMS. The user account must have administrator privileges. By default the domain and user name of the account installing ArcIMS is provided.
Select the ArcSDE services you want to be monitored.
The ArcIMS post installation setup checks for valid ArcSDE
services in the ArcSDE services.sde file and in the Windows registry under
\HKEY_LOCAL_MACHINE\SOFTWARE\ESRI\ArcInfo\ArcSDE\ArcSDE for <dbms type>.
Valid ArcSDE services found will be listed under SDE services. Select
the ArcSDE service you would like to monitor and click the 
button.
To monitor a valid ArcSDE service that is not listed, use the Other button.
When a valid ArcSDE service is chosen, the post installation setup will
edit the <ArcIMS Installation Directory>\ArcIMS\Server\monitor\sde.properties
file with the following parameters:
instanceNames=<your
ArcSDE Service name>
portNumbers=<your
ArcSDE Service port>
sdehomes=<your
ArcSDE Service's Home>
The installer will also edit the Monitor.properties file
located at <ArcIMS Installation Directory>\ArcIMS\Server\monitor
and uncomment this line: sdePropertiesFilename=Sde.properties
If you have a typo or error in either of these files, when you reboot or attempt to start the ArcIMS Monitor, your ArcIMS Monitor may not start.
Note: Microsoft’s Java Virtual Machine (VM) 3186 or later is required for the ArcIMS Monitor Windows Service. The installation updates your system if Java Virtual Machine is not detected or if you have an earlier version.
You need to configure your Web server to use ArcIMS Service Administrator. The ArcIMS Service Administrator presents a unified interface for managing ArcIMS and ArcSDE. If you want to use the ArcIMS Service Administrator to remotely administer ArcSDE Services, you must configure your Web Server. The post installation will configure your Web server for you, See Web server-servlet engine configuration. If you choose to manually configure your Web server, See Configure your Web server for ArcIMS Service Administrator, for options on manually configuring your Web server for ArcIMS Service Administrator.
