Cluster Properties: Administration Tab
SmartCluster Properties Dialog Box (Administration Tab)

Description--

Use this tab to select your SmartCluster Administrative Manager, modify the existing license key, and enable or disable Bright Tiger Authentication, and enable or disable session aware load balancing.

1.	Administrative Manager -- This field lists the current administrative manager. In each Bright Tiger SmartCluster, one of the Web servers is designated as the administrative manager. When a SmartCluster is created, the first server added becomes the default administrative manager. You can change the designated administrative manager if you need to delete the server that's currently the administrative manager. The administrative manager is responsible for allowing other Web servers to be added and deleted from the SmartCluster.

2.	License Key -- This field specifies the current license key for this SmartCluster. The user can update the license key by modifying this field. The Web server acting as the administrative manager must be accessible in order to change this field.

3.	Authentication Mode -- These fields let you specify the mode of Authentication you want to implement on a per-SmartCluster basis.

The modes include --

No Authentication

When Authentication is turned off on a specific SmartCluster, any ClusterCATS Explorer can add that SmartCluster to their Cluster Manager view. Once the SmartCluster is added, you will have unrestricted access to the content in that SmartCluster.

Windows NT Domain Authentication

Note: Windows NT Domain Authentication does not work on ClusterCATS on Windows 95. Before you can enable NT Domain Authentication on any specific SmartCluster, you must create a special global group with a name in the form of, "BT_Clustername" within that domain.

You or the domain administrator can do this through the standard Windows NT User Manager system management utility. Once you create a "BT_Clustername" group, any of the members you add to that group are authenticated to view the SmartCluster. All members of the SmartCluster must be from the same Windows NT Domain unless a trust relationship has been set-up by the system administrator. A “BT_Clustername” global group must exist in the domain from which the ClusterCATS Explorer is executed. ClusterCATS Explorer determines what servers exist in which NT Domain by communicating with any Windows NT Domain controller for the domain. The list of servers that exist in the Windows NT Domain can be viewed by looking at the Network Neighborhood Windows NT utility. If no trust relationship exists, then SmartCluster members must be from the same Windows NT Domain.

Cluster/Server-based Local-User Authentication

In the Authentication field, select Local User. Click on OK. Local User authentication for the selected cluster is enabled. Only authorized administrators can add the cluster to their ClusterCATS Explorer view.

Make sure all authorized users for Local User Authentication have an account on each machine running the IIS server and are listed in a local group with the name “BT_clustername" where the cluster name is name of the cluster. Alternatively, authorized users can also be administrators listed in the Administrator's Group (on each machine running the IIS server).

5.	Password --  Password for the account

6.	Remember Box -- Click here if you want Bright Tiger to remember the account password between sessions and not prompt you the next time you added a SmartCluster to your view.

7.	Enable Session-Aware Load Balancing  — When this feature is enabled, the ClusterCATS software only load balances users off the current Web Server when the user is establishing a new session. A new session is defined as a user typing in a URL, using a bookmark, or by following a link from another site. Once the session is established the user will not be load balanced off of that Web Server.

This feature is an alternative to the "Do not redirect on server busy" found in the folder property box.

8.	Load Balancing Product -- Configure ClusterCATS to work When this features is enabled ClusterCATS  will be configured to work in conjunction with a third party hardware load balancing device or load balancing software products.

The procedure for logon to the database depends on which user authentication scheme is set up by the database administrator (DBA).

“Database Authentication” is used when the DBA requires an explicit logon to the database.

“Operating System Authentication” is used when the DBA requires only a logon to the operating system. In the latter case, the DBA must configure the database appropriately. For Microsoft SQL Server, this means configuring the database for trusted connections. For Oracle7, this means configuring the users via the OS_AUTHENT_PREFIX parameter. See the database documentation for further details. ClusterCATS Explorer requires non-empty passwords for both Authentication schemes.

1.	User Account – Username registered as an authorized database account.

2.	Password -- The password for the specified user account.

3.	User Account – Authorized username for an operating system login.

4.	Password -- The password for the specified user account.


New Application Probe Dialog Box
Application and Bright Tiger URL Probe Dialog Box

Use this dialog box to create an Application probe. An Application probe periodically executes and returns a value of success or failure. The probe can be any executable performing any tasks and returning success of failure code. On failure, the monitored URL is marked as restricted. Specific information required by this dialog box includes:

1.	Web Server -- The Web server where the application probe will run.

2.	Pathname -- The full pathname of the probe file that will be periodically executed.

3.	Working Directory -- The working directory the application should use during execution. This is usually the same directory where the probe files reside.

4.	Startup Parameters -- Parameters, if any, passed to the probe on execution.

5.	Timeout -- How long should Bright Tiger wait without a response from the probe before considering failure.

6.	Frequency -- How often should the probe run.

7.	Return Value -- What return value represents success?

8.	Register Button -- Registers the probe into the probe database. Note that registration will fail if any of the information you've entered into the dialog box is incorrect

9.	Log On As -- Click here to specify the user account the probe will run under on the Web server. By default, the probe will be run using the administrator's account.

10.	Defaults -- Press this button process through available probe locations in this monitor.

URL Probe

ClusterCATS provides an application probe that gives the ability to periodically "test" a URL that creates dynamic content (such as an ASP application).  If the URL fails or times out, ClusterCATS restricts web content specified by the administrator.   The content will become available as soon as the URL returns a successful value.  ClusterCATS refers to this feature as the URL Probe.  The ClusterCATS URL Probe is distinguished by the fact the URL Probe requests will not get load balanced, assuring that the URL is always being tested.

To specify the URL Probe in the ClusterCATS Explorer:

Create an application probe on the content you want to be restricted when the URL Probe fails. Fill in the following fields for the Application Probe:

Field	Value	Description
Web Server:	Server1.company.com	The server on which to run the URL probe.
Pathname:	C:\Program Files\BrightTiger\Program\ProbeURL.exe	Fill in the directory portion with where you installed BrightTiger.
Working directory:	C:\Program Files\BrightTiger\Program\	Fill in the directory portion with where you installed BrightTiger.
Startup parameters:	http://www1.company.com/test.asp	The URL to probe.
Timeout(sec):	120	We recommend 120 seconds.
Frequency (sec):	180	Choose your own value for how often you want to run the probe.
Return Value:	200	200 is a successful return value
FindText Probe

ClusterCATS provides an application probe that gives the ability to periodically "test" a URL that creates dynamic content (such as an ASP application), it also lets you verify the correctness of the returned content.  Correctness is verified by comparing the content returned from the get with a user specified string.  If the URL fails, times out, or the user supplied string was not returned in the page accessed, ClusterCATS restricts web content specified by the administrator.   The content will become available as soon as findtext returns a successful value.  ClusterCATS refers to this feature as the FindText Probe.  The ClusterCATS FindText Probe is distinguished by the fact the FixText Probe requests will not get load balanced, assuring that the URL is always being tested.  The FindText probe is similar to the UrlProbe, the only difference being that FindText verifies that the page returned contains the user supplied string.

To specify the FindText Probe in the ClusterCATS Explorer:

Create an application probe on the content you want to be restricted when the FindText Probe fails. Fill in the following fields for the Application Probe:

Field	Value	Description
Web Server:	Server1.company.com	The server on which to run the FindText probe.
Pathname:	C:\Program Files\BrightTiger\Program\FindText.exe	Fill in the directory portion with where you installed BrightTiger.
Working directory:	C:\Program Files\BrightTiger\Program\	Fill in the directory portion with where you installed BrightTiger.
Startup parameters:	http://mysite/test.asp  my-test-string	The URL to probe and the string to look for
Timeout(sec):	120	We recommend 120 seconds.
Frequency (sec):	180	Choose your own value for how often you want to run the probe.
Return Value:	0	200 is a successful return value
Bat Probe

ClusterCATS provides an application probe that gives the ability to periodically execute dos command files (bat files).  The command file must however be launched from the BatProbe.exe application probe supplied in the Program directory of your ClusterCATS installation. In order to ensure that the proper return codes are passed back to ClusterCATS from the command file, you must use  BatReturn.exe (supplied in the ClusterCATS Program directory) to set the exit status from the bat script. If the bat script fails or times out, ClusterCATS restricts web content specified by the administrator. The content will become available as soon as the bat script returns a successful value.  ClusterCATS refers to this feature as the Bat Probe.  The ClusterCATS Bat Probe is distinguished by the fact the URL Probe requests will not get load balanced, assuring that the URL is always being tested.

To run multiple dos command files as application probes, simply make multiple copies of BatProbe.exe, each with a unique name, and configure an application probe for each.

To specify the Bat Probe in the ClusterCATS Explorer:

Create an application probe on the content you want to be restricted when the Bat Probe fails. Fill in the following fields for the Application Probe:

Field	Value	Description
Web Server:	Server1.company.com	The server on which to run the bat probe.
Pathname:	C:\Program Files\BrightTiger\Program\BatProbe.exe	Fill in the directory portion with where you installed BrightTiger.
Working directory:	C:\Program Files\BrightTiger\Program\	Fill in the directory portion with where you installed BrightTiger.
Startup parameters:	C:\temp\script.bat <success-code> arg1 ...	The fully qualified path of the script to run, successful  return code,  list of arguments to pass to the command file.
Timeout(sec):	120	We recommend 120 seconds.
Frequency (sec):	180	Choose your own value for how often you want to run the probe.
Return Value:	0	Supply successful return value

Cluster Properties: Net Distance Tab
Cluster Properties -- Network Distance

Selection of a Preferred Server: Using ClusterCATS Network Distance

You can optionally configure a Bright Tiger SmartCluster with the Network Distance option to allow users to access a preferred server or set of servers in a cluster on a regular basis. This improves overall cluster performance for SmartClusters with servers in more than one physical site by minimizing traffic over slow links when users are directed to the closet server. Typically, the preference is based on which server is the shortest network distance from the browser.

The user’s preferences are stored in cookies located on the user’s browser. A cookie provides the mechanism to direct requests back to the user's preferred servers. Cookies are created the first time a user contacts a cluster or whenever an old cookie expires.

1.	Enable network distance -- Bright Tiger ClusterCATS is shipped with Network Distance turned off by default. To enable it, you must turn it on from the Cluster Properties Dialog box, Net Distance Tab. Click on Enable network distance. Bright Tiger Network Distance is now enabled.

2.	Determine network distance using  -- Select one of the following methods to determine Network distance.

3.	Trip time -- Select this option to compute which server in the SmartCluster is closest to the user based on the trip time from the user's browser to a server.

4.	First server contacted -- Select this option to have network distance selected based on the first server the user's browser contacts the first time it accesses the SmartCluster.

5.	Refresh frequency -- In the Refresh frequency section, select a method by which to determine cookie lifetime: either per browser session or by a fixed time: days, hours, and minutes. A new Bright Tiger cookie will be generated when an old one expires.

6.	Browser Session -- Duration of a single browser session.

7.	Fixed time period --  Specify the length in days, hours, or minutes

8.	Set network distance scope to -- On the Net Distance tab in the "Set Network Distance Scope to" section, select the scope to which you want network distance set in this SmartCluster. You have the following choices:

9.	Single domain -- Sets one cookie for the whole domain. The domain level specifies the depth of the Web Servers domain. If all the web servers in the cluster are in the same subdomain, use this option. For example, www1.brighttiger.com and www2.brighttiger.com, are both in the domain brighttiger.com, which is a level 2 domain. One cookie can be used for accessing both servers.

10.	Multiple domains -- Sets one cookie per subdomain if your cluster lives across several subdomains in a company. You should set this option if you have four servers in two different domains, such as www1.east.brighttiger.com, www2.east.brighttiger.com, www3.west.brighttiger.com, www4.west.brighttiger.com. In this case, with a domain level set to 3, 2 cookies will be sent, one for east.brighttiger.com and one for west.brighttiger.com.

11.	Per server-- Sets one cookie per server. A different cookie for each server in the SmartCluster. Netscape 4.0 has an option that users can set to only accept cookies from the server of origin. Per server cookies are required if the user has selected this option.


Cluster Properties: Web Applications Tab
Cluster Properties -- Web Applications Tab

Description

Use this tab at the cluster level when the cluster contains an application that requires the URL that uses a path information field. Microsoft FrontPage, server extensions, and CGI applications that use the path information field of the URL will not be redirected unless this information is supplied.

The following is an example of  a URL using path information:

Http://servername/_vti_bin/shtml.dll/search.htm

Where:

_vti_bin/shtml.dll is a Microsoft FrontPage server extension

search.htm is the path information

In order to redirect the URL the Application Path needs to be filled in with _vti_bin/shtml.dll

If the administrator would like the ability to failover the URL based upon the availability of the path information, search.htm, the Working Directory must also be provided. In this example search.htm lives in the directory _vti_cnf/, so the Working Directory should be specified as _vti_cnf/. If search.htm becomes restricted, either manually or via a probe failure, the URL is redirected to another SmartCluster member.

1.	Web App(lication)s Tab

2.	Application Path – The full application path relative to a server’s WWWroot directory.

3.	Working Directory – The location where the application tries to resolve the path information into a URL name.  The working directory is optional.

4.	Create New Entry Button – Click here to create a field for a new entry. The cursor will be automatically moved there.

5.	Delete Selected Entry Button – Click here to delete the currently selected path information entry.

Event	Description	Notification
Disk Failure	Receive an alarm when any of the virtual directories for a ClusterCATS Web server is not available.	Immediately
HTTP Server Failure	Receive an alarm when ClusterCATS notices that the Web Server is not running and cannot be restarted by ClusterCATS.	Immediately
Probe Failure	Receive an alarm when a probe registered by the ClusterCATS administrator has failed, requiring the specified URLs to be marked restricted.	Immediately
Replication Failure	Receive an alarm when replication has failed. The ClusterCATS log file will contain the detailed information.	Immediately
Server Busy Warning	Receive an alarm once a day with the peak load of your system for the last 24 hours.	Every 24 hours
Server Unreachable	Receive an alarm when a Web Server is no longer reachable.	Immediately
Web Server Failover	Receive an alarm when a ClusterCATS server has taken over an IP address of a failed cluster member.	Immediately
Low Disk-Space Warning	Receive an alarm when the disk space on the disk where ClusterCATS is installed is low.	Immediately


Wizard -- Session State Management

Description

If you have applications running on the web servers in the cluster that maintain session state information on each individual web server, then select “Yes.”  When this feature is enabled, a user’s first request may be redirected to a server with better response time.  Subsequent request will go directly to this server for the duration of the user’s session.

1.	Enable Session Aware --  Select yes or no.

2.	Back -- Return to the previous ClusterCATS Wizard page.

3.	Next -- Continue with the creation of your SmartCluster.

4.	Finish -- Complete the creation of your SmartCluster.


Wizard -- Load Balancing Device

Description

ClusterCATS can be configured to work in conjunction with a third party hardware load balancing device or load balancing software product. If you are not using a load balancing device, proceed to the next page. ClusterCATS needs to know the URL clients use to access the web servers through this load-balancing product.

To configure ClusterCATS to work with third party load balancers enter the following information:

1.	Load Balancing Device Name -- .  If you are using a third-party load balancing device or software product, enter the URL address for the web site (e.g. www.company.com).

2.	Back -- Return to the previous ClusterCATS Wizard page.

3.	Next -- Continue with the creation of your Smart Cluster.

4.	Finish -- Complete the creation of your SmartCluster.


Wizard -- Introduction

Description

A SmartCluster is a collection of two or more web servers, that are grouped together using ClusterCATS software. Each web server in the SmartCluster is referred to as a cluster member.  The Cluster Creation Wizard walks you through creating a SmartCluster for the first time. The Wizard takes you through following steps:

1.	Naming your cluster.

2.	Adding web servers to the cluster.

3.	Configuring the load management thresholds for each cluster member.

4.	Establishing alarm notification for system problems.

5.	Enabling session state management.

6.	Configuring support for third-party load balancing products.

You can update the configuration of your SmartCluster at any time after it's been created using the ClusterCATS Explorer.


Server Properties: Load Tab

Description

Load management policy is established through two administrator-defined thresholds -- the peak load and the gradual redirection threshold.  The peak threshold defines the maximum load. The gradual redirection threshold activates load management. The gradual redirection threshold is designed to prevent the ASP, CGI, Java or HTTP process from ever reaching the peak threshold and gradually redirects a percentage of all new requests received to the least loaded server.

1.	Load Balancing -- Turn on load management here. The value specified (0-100) is the percentage of  load at which the server will start redirecting all requests to other SmartCluster members.  A value of 0% redirects all the HTTP requests; a value of 100% disables load management.

2.	Gradual Redirection  -- Turn on gradual redirection here.  The value specified is the percentage of load at which the server will start gradually redirecting some requests to other servers in the SmartCluster.


Wizard - Final Check List

Description

Once you have completed the creation of your SmartCluster you can manage the server using the ClusterCATS Explorer.  If you add your servers to the SmartCluster in passive mode, the default you will to set the servers to active.

By default all Cluster Members enter the cluster in a passive state. In the passive state ClusterCATS is not actively load managing requests. All requests directed to a Cluster Member in passive state are passed directly to the web server, without any processing by ClusterCATS.  The reason a Cluster Member is brought into a cluster in a passive state is that you can test and configure the Cluster Member prior to activating the cluster.  In the passive state, ClusterCATS auto-discovers all content on the server (a process known as initialization), allows you to replicate content, and allows you to configure monitors. Note in the passive state if a restriction is placed on a server, directory, or file, the restriction will be displayed in ClusterCATS Explorer but ClusterCATS will not redirect the user request based on the restriction.

Once you have verified that a Cluster Member is functioning properly, it has completed the initialization phase, and you have configured the appropriate resource monitors, place the Cluster Member in an active state. To set a Cluster Member in the active state perform the following steps:

To set a Cluster Member in the active state perform the following steps:

1.	Select the Cluster Member and right mouse click.

2.	Click on Configure, then select the state tab.

3.	Toggle the Cluster Member from Passive member to Active member

4.	Select “OK”

5.	Repeat the above steps for each Cluster Member you wish to make an active member.
