Note The information in this chapter applies to UNIX workstations (Maps and SNA View) only. For information on using the administration application on Windows NT systems, see "Using CiscoWorks Blue SNA View Administration for Windows NT." |
This chapter presents an overview of the procedures necessary to administer the CiscoWorks Blue Maps and SNA View user applications. As administrator, your job entails using the various CiscoWorks Blue administration programs to:
This chapter includes the following main sections:
At the end of product installation, you are asked whether you want to start the CiscoWorks Blue servers and processes. If you answered Yes, the following servers are started:
Any processes marked as autostart are started by the Process Manager. On a UNIX workstation, you can see which programs have been started by using the cwb show status command:
/opt/CSCOcb/bin/cwb show statusThe output from this command shows you the status and process ID of all servers and processes. The Last Message column displays the last message sent by the process to the Process Manager.

This section describes the ongoing administration tasks that you will perform after successful installation of the CiscoWorks Blue products. This section includes the following information:
To run the CiscoWorks Blue Maps and SNA View applications and their supporting servers and processes, you must obtain and apply the appropriate license information. You obtain licenses from Cisco to run Maps and SNA View and you apply the license information in one of the following two ways:
The Process Manager client lets you view the status of processes and daemons and it lets you start and stop the processes and daemons. You can start the Process Manager client in one of the following ways:
On a UNIX workstation, use the cwb show status command to monitor the status of the CiscoWorks Blue servers and processes:
/opt/CSCOcb/bin/cwb show statusFor information about using the Process Manager, see "Using the Process Manager."
You can also use the cwb run script to start processes, daemons, user applications, and other administrative programs from the command line, as described in "Commands and Processes for UNIX Systems."
The Message Log client lets you view the messages that are logged by CiscoWorks Blue processes and control the kind of messages that are logged. You can start the Message Log client in one of the following ways:
For information about using the Message Log, see "Using the Message Log Viewer."
On a UNIX workstation, the /opt/CSCOcb/etc/cwbinit file contains default values used by most of the CiscoWorks Blue applications.
Before you can use the APPN Motif application, you must specify a network topology agent, as described in the "Selecting a Network Topology Agent" section.
When you start the APPN Motif application, you can specify a network topology agent in a dialog box. When you select APPN from the CiscoWorks Blue web page, you must already have a network topology agent specified in the /opt/CSCOcb/etc/cwbinit file to view network topology information. You do not need to specify a network topology agent to view node local details and SNA session information.
To link from the CiscoWorks Blue web page to web pages for NetView for OS/390 and CiscoWorks 2000, you can set these URLs in cwbinit, as described in the "Starting and Stopping the Web Server" section.
Use the cwbinit file to set polling intervals for DLSw and RSRM devices, as described in the "Starting and Stopping the Web Server" section.
Use the cwbinit file to specify values to control the cwbsnamapsd web daemon, as described in the "Starting and Stopping the Web Server" section.
To correlate the SNA PUs with the TCP/IP routers, you must run the SNA host discovery process. If, during installation, you select a TCP connection to the mainframe, then the Process Manager automatically starts the cwbhcid daemon to start a host connection.
To start the daemon in the Process Manager, click cwbhcid_domain and click Start. If you selected an LU 6.2 connection to the mainframe, you must first configure the LU 6.2 transaction programs as described in the section "Configuring the Host Connection" section. The CiscoWorks Blue mainframe application will actually start the connection to the workstation.
You can use a seed file for discovering routers and for specifying DLSw key routers. A seed file is a file that contains a list of routers to be discovered. You can list the routers in either of two formats:
router [ReadCommunityString] [key]
or
router:[ReadCommunityString]:[key]
Where key indicates that this is a DLSw key device. If you omit the word key, the router is not considered a DLSw key device.
For information about creating a seed file, see the "Discovering the Network" section and view the subsections specific for each protocol (DLSw, RSRB, TN3270, and APPN).
For DLSw applications, whether web-based or Motif applications, you should select several routers as key devices. For information about key devices, see the "Specifying the Status of Aggregated Peers" section.
Select key devices in one of the following ways:
You discover the TCP/IP-managed devices (routers) in the network to populate the CiscoWorks Blue database. During this time, the discovery process discovers and records every device in the network that supports any of the supported protocols (DLSw, RSRB, APPN, or TN3270).
Discover the network devices using the following applications:
|
Note To see SRB rings in DLSw views, including the SNA dependency views, use RSRB/SRB discovery from the Administration application. |
Discover the network devices in one of the following ways:
|
Note If you discover DLSw devices from a seed file, you should specify key devices in the seed file. |
During installation, (if CiscoWorks is also installed) user ID cwblue is created for running CiscoWorks Blue applications. The user ID is created without a password, so you may want to create a password for cwblue before you let users log in with it.
Run the product verification program to ensure that all the preceding tasks were done correctly. The verification program checks the contents of the configuration files and the CiscoWorks Blue database for accuracy and completeness and ensures that all the required servers and processes are running so that users can log in to the web page and use the Motif applications.
You can run the verification program from the administration program, as described in "Using the Administration Application," or by issuing the following command:
/opt/CSCOcb/bin/cwb verifyThe cwb command performs a variety of related administration tasks, such as starting and stopping servers and processes and displaying status. The cwb command is summarized here, but is explained in full, with command line options, in "Commands and Processes for UNIX Systems."
See "Commands and Processes for UNIX Systems" for information about the processes that you can start and stop. The cwb stop all command stops the Process Manager too. Use the cwb kill all command only when you cannot stop processes normally.
Before you access the CiscoWorks Blue web page from a web browser, ensure that the web server is running on the workstation on which the CiscoWorks Blue applications are installed. To determine whether a web server is running, enter the following commands on a UNIX workstation:
cd /opt/CSCOcb/binIf the CiscoWorks Blue web server is not running, you can start it using the Process Manager.
The CiscoWorks Blue web server starts using the port that was configured during installation and configuration. The order of port selection is as follows:
1. Use port 80.
2. Use port 8080.
3. Ask installer for unused port.
On a UNIX workstation, you can browse the file /opt/CSCOcwbC/apache/etc/httpd.conf to find the port being used.
If you change the cwbinit file while the application is running, you must reset the process to activate the changes to cwbinit.
The following sample of the cwbinit file shows just the values that apply to the cwbsnamapsd application:
# ********************************************************************
# This section is used by the cwbsnamapsd server process, which
# handles requests from the web interface.
# default socket number for communication with cgi-bin programs
socketCgi-AppServer = 51999
# default number of threads for cwbsnamapsd.
# Valid range of values is 1 to 30.
# Increase the number to allow more concurrent web browser users,
# decrease the number to limit CPU utilization on the server.
socketPoolThread = 10
# cgi-bin wait time on response from cwbsnamapsd, in seconds.
# This is used to clean up outstanding requests in case of a hang or
# other problems with cwbsnamapsd.
# Increase this value only if time outs occur because of extremely
# slow network (snmp) or database responses.
cgiBinWaitTimeOut = 120
# TME 10 NetView for OS/390 Web Interfaces
#
# This is used to configure the NetView Web Interfaces used by the
# Maps/SNA View. Each NetView login must contain a name and URL
# separated by a '^' character.
#
# The name is any identifier that you want to associate with the
# NetView login. The URL is the fully-qualified address of the
# NetView web interface.
#
# You may specify multiple NetView logins, each of which must be
# separated by a ',' character:
# netViewInterfaces = name^url,name^url,name^url
# For example:
# netViewInterfaces = Joe's NetView^www.myhost.com,Bob's
# NetView^www.myhost.com/~bob
netViewInterfaces =
# CiscoWorks 2K Web Interface
# This is used to indicate the URL of the CiscoWorks 2000 Resource
# Manager Essentials

# ciscoWorksURL = http: //<host name>:<port>
ciscoWorksURL =
# SNA Filter Request Database Limit
#
# Whenever you make a request to the database, the application first
# calculates the amount of data that needs to be processed to service # the request. This parameter indicates at what point the request is # considered too big and should not be processed.
#
# When you submit a request, the 'cgiBinWaitTimeOut' parameter
# controls how long the browser will wait until it times out. If you
# submit a huge request to the database (like 'LU Name=*'), the web
# server will most likely timeout before the database ever finishes
# processing the request. This parameter is used to filter out those
# requests that will probably never finish before the web browser
# times out. You will get a message on the web interface informing
# you that this limit has been reached, and you should refine your
# search.
#
# You can adjust this parameter to suit your needs. The higher the
# number, the larger the request the database will try to handle.
# Keep in mind, however, that a larger number will cause the database
# to work harder, thereby affecting system performance and blocking
# database access to other users of this application.
#
# In the normal course of operations, the requests to the database
# should not be all that large. If they are, then the users of the
# product should
# narrow down their requests to the database by specifying more
# precise data in the SNA Filter search screens.
maxRowCount = 5000
# SNA View Sessions and Session Connectivity Field Suppression
#
# The following allow the indicated field name and the related
# contents to be suppressed in the Sessions table and on the Session
# Connectivity display. By default, all fields and their associated
# values are displayed.
# To suppress a field and its contents, uncomment the field entry. You
# may want to do this to reduce the Sessions table width or to block
# sensitive data from being displayed to SNA View users.
#
# To turn on the field name suppression, set the associated variable = # on. Valid values : on/off. default value : off.
#suppressLUName = on
#suppressPU2Name = on
#suppressFEPName = on
#suppressLogicalLineInfo = on

#suppressDLURName = on
#suppressDLUSName = on
#suppressNodeName = on
Use the socketCgi-AppServer value to specify the socket number to use when communicating with cgi-bin web programs. The default socket number is 51999.
Use the socketPoolThread value to specify the number of threads for cwbsnamapsd. The valid range of values is 1 to 30. The default is 10 threads. You can increase the number of threads to allow more concurrent web browser users, and you can decrease the number of threads to limit CPU use on the server.
Use the cgiBinWaitTimeOut value to specify the cgi-bin wait time on response from cwbsnamapsd, in seconds. This value is used to clean up outstanding requests in case of a hang or other problems with cwbsnamapsd. Increase this value only if time outs occur because of extremely slow network (snmp) or database responses. The default value is 120 seconds.
Use the netViewInterfaces value to configure the NetView web interfaces used by the CiscoWorks Blue web page. Each NetView login must contain a name and URL separated by a "^" character.
You can specify multiple NetView logins, each of which must be separated by a comma (,) in the following format:
netViewInterfaces = name^url,name^url,name^url
For example, you might enter the following:
netViewInterfaces = Joe's NetView^www.myhost.com,Bob's NetView^www.myhost.com/~bob
Use the ciscoWorksURL value to configure a CiscoWorks 2000 web Interface. This value is used to indicate the URL of the CiscoWorks 2000 Resource Manager Essentials package. Use the following format:
ciscoWorksURL = http: //host_name[:port]
Where:
host_name is the host name of the host running the CiscoWorks 2000 web Interface.
port is the port number on that host, if it is not port 80.
Use the set of "SNA View Sessions and Session Connectivity Field Suppression" variables to do the following:
Initially, the session suppression entries are set as comments so they are not active. Each value lets you suppress one or more related fields. For example, to suppress the display of the IDBLK/IDNUM field, you would uncomment the suppressIDBLKNUM line, as shown below:
suppressIDBLKNUM = on

You can use various methods to control access to the CiscoWorks Blue web page. You can find documentation about Apache security features at the following web sites:
The CiscoWorks Blue web server supports both htpasswd and dbmmanage methods of user authentication documented in these URLs.
After you install Maps and SNA View, your Maps and SNA View users can elect to use a web browser to access the applications. These users start their web browsers and type the URL of the CiscoWorks Blue web server:
http ://host_name[:port_number]/
Where:
host_name is the name of the host on which you installed Maps or SNA View.
port_number is the number of the port used by the web server. If port 80 is used, the port number can be omitted.
For example, if your host name is host.cisco.com, and the port is 8080, users would type:
http ://host.cisco.com:8080/
If your host name is host.cisco.com, and the port is 80, users would type:
The doDNSSearch variable in the cwbinit file lets you specify that a domain name server (DNS) lookup will be done for queries to routers during discovery and polling. For example, using DNS lookup, a device that was discovered as heritage.cisco.com could also be referred to as heritage. You can set this variable so that you can enter a different name that will be resolved by a DNS lookup. This variable is used when you do the following:
The following new section of the cwbinit file provides the doDNSSearch variable:
# *****************************************************************
# boolean value is used by both the cwbsnamapsd server process
# and other processes such as cwbadmin, cwbdiscover, dlsw and rsrb to
# add devices to the database.
# When adding a device to the database, this value is used to decide
# whether to do a DNS lookup on the name of the device being added,
# storing the DNS name in the DNS database table.
#
# cwbsnamapsd uses this value to decide whether to do a DNS lookup on
# a device name supplied in a user's request, if the request could
# not be satisfied with a device name or IP address lookup.
# The default value is "false", DNS lookups are not enabled. Set this
# value to "true" to enable DNS lookups.
doDNSSearch = false
You can set the doDNSSearch variable in the cwbinit file to true to discover and query routers by any valid name. Now you can enter the discovered name, a valid IP address, or any valid name for the router. For example, you could enter cwb-c5 in the input field for a DLSw focus view even if the router was discovered as cwb-c5.cisco.com. To enable domain name server lookup for routers, change the doDNSSearch value to true:
doDNSSearch = true
The DNS lookup is performed when the router is added to the database and any time a device cannot be found by the discovered name or IP address. This lookup might impact performance.
|
Note After you change the doDNSSearch parameter, you should stop and restart cwbsnamapsd. |
During installation, the CiscoWorks Blue products save the host name of the workstation in a set of files for use during processing. If you later change the host name of the workstation, you must also change the host name in those files.
To change the host name, use the following procedure:
Step 2 Change the host name in the following files:
Step 3 Use the following command to restart all Cisco Works Blue processes:
/opt/CSCOcb/bin/cwb start serversThe CiscoWorks Blue products do not include the local workstation's IP address in any of its files, so you can change without impact.
