Internet Express for Tru64 UNIX Version 6.8 Administration Guide (14233)

Note:
If the locker account exists from a previously installed version of Internet Express, the iass
account is set up as an alias for the locker account.
1.4 Accessing and Managing the Internet Monitor
The HP Internet Monitor software allows administrators to monitor Internet services running
on a Tru64 UNIX system. The Internet Monitor product can be accessed directly or from the
Administration utility for Internet Express.
To access the Internet Monitor from the Administration utility:
1. Choose Manage Components from the Internet Express main menu.
2. In the Manage Components table, click on Internet Monitor under Quality of Service. The
Internet Services Administration server prompts for your user ID and password, then lets
you proceed.
To enable or disable the Internet Monitor from running, you use the Start/Stop the Internet
Monitor menu option from the Administration utility. For details, see the Internet Monitor
Administrator's Guide.
To configure the Internet Monitor components, see the Internet Monitor Administrator's Guide.
1.5 Managing Internet Express in a TruCluster Environment
TruCluster Server software provides high availability for Tru64 UNIX systems. This chapter
describes the special considerations to administer Internet Express running in a cluster running
TruCluster Server Version 5.0 and higher software.
1.5.1 Using Internet Express Services in a Cluster
If you are running Internet Express in a cluster, be aware of the following considerations:
• For all services, use the cluster alias to access the service to provide highest availability. All
services have been configured to allow the cluster alias to be used.
• InterNetNews, Squid, Internet Relay Chat, OpenLDAP, and Tomcat run as single-instance
servers. Only one instance of these servers will be run within the cluster. The/sbin/init.d
scripts have been modified to use Cluster Application Availability (CAA) for these services.
The service names are innd, squid, ircd, and slapd respectively.
• The Secure Web Servers and the sendmail daemon run on all cluster members concurrently.
Connections are distributed amongst the cluster members based on how the cluster alias
has been configured. See cluamgr(8).
• All other services use inetd to make connections and start server processes. Connections
are also distributed for these services among the cluster members.
1.5.2 TruCluster Impact on Internet Express Administration
There are some specific variations of the Administration utility user interface if you are running
Internet Express in a TruCluster Server cluster environment. These variations include the
following:
• Depending on the type of service, the active status of the service for each member where it
may run is displayed.
• Starting and stopping a service applies to the entire cluster. If more than one instance of a
service is running in the cluster, all are affected.
• Some information is specific to each member in the cluster. In these cases, a listbox is
displayed at the top of the page, indicating which member is being affected. The listbox
contains all cluster member names; selecting a different member will cause the display and
