This section describes requirements for oracle user logins for installation and autoboot.
If the oracle login is enabled for interactive mode, the installation or boot will hang. This usually happens if the login scripts, such as .cshrc, .login, and .profile, invoke the coraenv or oraenv scripts provided by Oracle. If these scripts are invoked by the oracle user login and if the ORAENV_ASK variable is set to YES (default) prior to invocation, then interactive environment variable settings confirmations are required. This is not possible during the APM installation or at boot time.
The following example for C shell describes the step to take to request non-interactive coraenv script operation.
In the oracle user .cshrc file (or similar startup file), add the following lines to clear the ORAENV_ASK environment variable:
setenv ORAENV_ASK NO source /opt/bin/coraenv [or an alternate location] unsetenv ORAENV_ASK
The APM installation package contains scripts for automatically creating the APM database. For more information on the APM database installation, refer to the README.database file on the CD-ROM in the cdrom0/CSCOapm/reloc directory. After installation, this file is also included in the /opt/CSCOapm directory.
The following issues are related to Netscape Navigator and Netscape FastTrack Server software.
For APM to work properly, you must run it from a browser that has Java enabled. If you try to run APM from a browser that does not support Java or does not have Java enabled, you will receive the following message:
Error: APM requires a Java-enabled browser
If you are using Netscape Navigator 3.01 (recommended for APM 2.0), you can enable Java using the following steps:
Step 1 Select Options>Network Preferences>Languages and check the Enable Java option.
Step 2 Either exit and reload Netscape before starting up APM, or hit the Reload button to reload APM.
The Netscape cache can become corrupted due to the multiuser functionality of APM. If you receive messages that applets cannot start, you should clear the Netscape memory and disk caches.
Step 1 Select Options>Network Preferences. Click the Cache tab.
Step 2 Click Clear Memory Cache Now.
Step 3 Click Clear Disk Cache Now.
Step 4 Click OK.
Step 5 Click Reload on the Netscape main window.
Cisco APM uses modal dialog windows to display warnings. Generally, when an application displays a modal window or dialog, the application stops responding to any event (mouse action, keyboard entry, and so on) other than the event associated with the modal window (you must first respond to the modal window).
If you overlay the modal window with any other application window (the modal window now is "invisible"), the application will appear frozen.
If your browser window appears frozen, ensure that there is no modal window that has inadvertently been covered.
When a timeout occurs, a Netscape FastTrack "Connection timed out" message will appear in the Reports output frame (the bottom of the frame).
To determine if this message is because of a timeout, look at the FastTrack error log file (located in opt/CSCOapm/ns-home/httpd-apm_server_name/logs/errors). If the message is because of a timeout, you can increase the FastTrack timeout parameter.
To increase the FastTrack timeout parameter, add the following line to the FastTrack magnus.conf file (in the opt/CSCOapm/ns-home/httpd-apm_server_name/config directory):
Init fn=init-cgi timeout=nnn
where nnn is the number of seconds to wait.
You can increase the number of seconds to 600 (10 minutes) or 900 (15 minutes).
You must stop and restart the web server to enable this change. To restart FastTrack, enter the command:
/opt/CSCOapm/ns-home/httpd-apm_server_name/restart
or:
/opt/CSCOapm/ns-home/httpd-apm_server_name/stop /opt/CSCOapm/ns-home/httpd-apm_server_name/start
where apm_server_name is the name of the APM server.
In order to download, store, and view HTML reports graphs on your computer, you need a copy of an applet called graph.class in the directory where you store your HTML graph files. Follow this procedure to set up HTML graph reports viewing.
Step 1 In Netscape, open the http://apm_server_name/results/ web site (where apm_server_name is the name you have assigned to your APM server).
Step 2 Download the graph.txt file to the directory on your hard drive where you will be saving and opening HTML graph reports.
Step 3 Rename the graph.txt file as graph.class.
You can now view any of the graphical HTML reports in this directory. You can also copy this graph.class file to any other directory from which you will be opening HTML graph reports.
This section describes suggestions for optimum use of Cisco AccessPath Manager Software Release 2.0. Where applicable, the software caveat includes the Cisco DDTS tracking number enclosed in square brackets: [CSCdjxxxxx]
The following caveats relate to APM installation or upgrade.
As documented in the APM CD-ROM booklet, the HP OpenView daemons must be running during the installation of APM if the user will be performing HP OpenView integration during the installation.
If HP OpenView is not running during APM installation, you will receive the following error messages:
5:47:55 INFO: Adding APMovRecTraps as an OpenView daemon application... ovspmd: Object manager APMovRecTraps is not registered. See ovaddobj(1m). ovspmd: Object manager APMovRecTraps is not registered. See ovaddobj(1m). 15:47:56 INFO: AccessPath - HP OpenView Integration Complete. 15:47:56 INFO: End APM HP OpenView Integration script (11/18/97 15:47:56) 15:53:03 ERROR: Startup of HP/OV APM Trap Manager failed! WARN: 1 or more APM services failed to startup!
This problem should only happen if the user stops the HP OpenView daemons after answering all the installation script questions but before the postinstall script (which performs HP OpenView integration) begins.
To recover from this situation, perform the following steps:
Step 1 Remove the APM installation using the pkgrm command described in the "Removing APM Software" section of the APM CD-ROM booklet.
Step 2 If the removal of APM was successful, continue with Step 3. If the removal was unsuccessful, you might receive the following messages:
ovspmd: Object manager APMovRecTraps is not registered. See ovaddobj(1m). ovspmd: Object manager APMovRecTraps is not registered. See ovaddobj(1m).
If you see these messages, enter the pkgrm command again. When you no longer receive these errors, continue with Step 3.
Step 3 Make sure all of the HP OpenView daemons are running correctly by running ovstop then ovstart.
Step 4 Start the APM installation process again. This procedure is detailed in the APM CD-ROM booklet and the Cisco AccessPath Manager Configuration Guide. [CSCdj59951]
If you answered no to the question "Automatic install of APM database?" (to perform a manual database configuration), you must complete the database installation manually.
The procedure for manual database configuration is the same as the procedure for configuring a remote database. The APM installation package contains scripts for automatically creating the APM database. The APM_dbcreate.sh script in /opt/CSCOapmdb/oracle/admin is the master database creation script for remote databases that invokes all the other necessary scripts.
For remote database support, tailoring of both the Client and Server SQL*Net is left to your local Oracle database administrator, who should be familiar with the specific Oracle installation.
For the APM product, the remote database name is defined by the $APM_REMOTEDB environment variable. If this variable is undefined, or if it is blank, then APM assumes that the database is local. Otherwise, APM attempts to connect to the database identified by the variable.
The following files might need to be edited for your particular Oracle installation.
Client configuration involves the tnsnames.ora file:
################
# @(#)tnsnames.ora 1.5 29 Feb 1996
# Filename......: tnsnames.ora
################
<remote db name> =
(DESCRIPTION =

(Host = <remote host>)
(Port = 1521)
)
)
(CONNECT_DATA =
(SID = APMDB)
(GLOBAL_NAME = <remote db name>)
)
)
Server configuration involves the listener.ora file:
################

# Filename......: listener.ora
# Node..........: <remote host name>
################
LISTENER =
(ADDRESS_LIST =

TRACE_LEVEL_LISTENER = OFF
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = APMDB)
(ORACLE_HOME = <root dir of installed Oracle>)
)
)
Refer to the README.database file in /opt/CSCOapm for further instructions regarding remote database setup. [CSCdj61415]
If you choose to do a manual database configuration, the installation script will perform only minimal verification of the variables you supply to the script.
Local database configurations receive verification that the ORACLE_HOME directory exists and for correct Oracle version and components, but with manual configuration the script checks only that the directory name supplied for ORACLE_HOME exists. [CSCdj61448]
AccessPath Manager requires Oracle Enterprise Server 7.3.2.2 software. If it detects Oracle Workgroup software, it will warn you of this fact but not instruct you on how to recover.
The warning is as follows:
11:11:20 WARN: Oracle Workgroup Server detected AccessPath Manager supports Oracle Enterprise Server 7.3.2.2 or higher. The installation program has detected an Oracle Workgroup Server product. At this time the Oracle Workgroup Server is not supported by AccessPath Manager. The installation will continue but it is possible that AccessPath Manager will not operate correctly with the Oracle Workgroup Server.
The recommended recovery from this condition is as follows:
Step 1 Abort the installation script. Press Ctrl-c.
Step 2 Install the Oracle Enterprise Server 7.3.2.2 software.
Step 3 Start the APM installation process again. This procedure is detailed in the APM CD-ROM booklet and the Cisco AccessPath Manager Configuration Guide. [CSCdj62142]
In order for the upgrade from APM 1.0 or 1.1 to APM 2.0 to be successful, you must have a fully functional and operational APM 1.0 or 1.1 system.
In order to upgrade from APM Release 1.0 or 1.1 to Release 2.0, you must follow the software upgrade procedure described in the Cisco AccessPath Manager CD-ROM booklet or the Cisco AccessPath Manager Configuration Guide.
If you enter the command for a first-time installation:
pkgadd -d /device [-a none]
where device is the device name of the CD-ROM drive, you will receive the following error message:
Current administration requires that a unique instance of the <CSCOapm> package be created. However, the maximum number of instances of the package which may be supported at one time on the same system has already been met. No changes were made to the system.
To perform the upgrade, enter the command:
pkgadd -a /device/apmadmin -d dir
where:
This is documented in the Cisco AccessPath Manager CD-ROM booklet and the Cisco AccessPath Manager Configuration Guide. [CSCdj54670]
If you attempt to upgrade from APM 1.0 or 1.1 to APM 2.0 and you abort the upgrade procedure or the procedure otherwise fails, you must manually restore the data saved in the directory /opt/$PKGINST/etc/tmp/upgrade_backup before attempting the upgrade again. This is because the upgrade might have failed after overwriting user files but before restoring those files.
You will be warned if the installation script detects any previous upgrade attempts. The message is as follows:
18:19:19 WARN: Previous upgrade backup directory found An existing upgrade directory /opt/CSCOapm/etc/tmp/upgrade_backup has been detected. This may be an indicator of a previous failed attempt at upgrading AccessPath Manager. If this is the case then continuing this installation session may cause loss of data!
To back up these files and get ready to attempt the APM upgrade again, follow these steps:
Step 1 Cancel the upgrade. Answer n when asked if you wish to proceed:
Do you wish to proceed? [y] n
The installation will be aborted.
Step 2 Manually restore the data:
(a) For both CSCOapm (local) and CSCOapmdb (remote) installations, restore the files in the oracle and APMDB directories:
% cd /opt/CSCOapmdb/etc/tmp/upgrade_backup % tar cf - oracle | (cd /opt/CSCOapmdb; tar xfBp -) % cd /opt/CSCOapmdb/etc/tmp/upgrade_backup/APMDB % tar cf - sql | (cd $APM_DBPATH; tar xfBp -)
(b) For CSCOapm (local) installations, you must also back up some files in the www, ns-home, and etc directories. Enter these commands:
% cd /opt/CSCOapm/etc/tmp/upgrade_backup % tar cf - www/cgi-bin/env | (cd /opt/CSCOapm; tar xfBp -) % cd /opt/CSCOapm/etc/tmp/upgrade_backup % tar cf - etc/defPasswd | (cd /opt/CSCOapm; tar xfBp -) % cd /opt/CSCOapm/etc/tmp/upgrade_backup % tar cf - ns-home | (cd /opt/CSCOapm; tar xfBp -)
Step 3 Start the upgrade again using the procedure in the APM CD-ROM booklet or the Cisco AccessPath Manager Configuration Guide. [CSCdj57209]
The following is a caveat related to removing APM.
Two scripts used to complete the removal of APM files are written to the /tmp directory. These files might be removed if the /tmp directory is purged.
If you will not be running the /tmp/CSCOapm_remove or /tmp/CSCOapmdb_remove command immediately after removing the APM software package, as directed by the instructions in the APM CD-ROM booklet, you should use the UNIX cp command to copy the appropriate file to another directory. [CSCdj61332]
This section describes software user interface caveats.
When choice menus or buttons do not apply during a shelf or stack configuration, the menu or button is made inactive and grayed out.
Although the text in the grayed out button or menu still displays a configuration choice, there will be no configuration related to this disabled item.
For example, in an E1/PRI configuration, Signaling Method is not applicable. The pull-down menu is grayed out, but it shows P7. Despite this display, APM will not attempt to configure Signalling Method. [CSCdj80583]
If you resize the Netscape Navigator browser window during the Create Stack process, the APM action buttons will disappear and you will receive the following error message:
java.lang.NoSuchMethodError
To avoid this situation, do not resize the browser during a Stack Add. [CSCdj88104]
To select a stack, click the stack label, not the stack icon. [CSCdj27561]
Any invalid combination of selection operations and objects will immediately display an error message. [CSCdj31787]
You cannot deselect a selected stack by clicking on it. To deselect a stack, select another device. [CSCdj30710]
The use of hot-key shortcuts is not supported in APM Software Release 2.0. [CSCdj31735]
The use of the tab key for cursor movement inside dialog boxes for Windows 95 is not supported in APM Software Release 2.0.
Iconized monitor and APM home page screens are not automatically updated by the poller. To see the current data for these screens after opening them up, click the Netscape Navigator Reload button. [CSCdj82256]
The APM display colors are unreadable if the Windows 95 PC is configured for 256-color display.
Make sure that your PC is configured for at least 16-bit color. This requires a minimum of 2 MB of video RAM in order to handle 1024x768 display. [CSCdj81920]
This section describes software configuration caveats.
The default configuration template for the Cisco 7206 in a Cisco AccessPath-TS3 stack without the Catalyst 5002 does not allow packets to be properly routed out of the stack. Both the Fast Ethernet 0/0 and the BVI 2 interfaces end up with the same IP address.
To fix this, create a custom template, and use it when configuring the Cisco 7206.
To create the new custom template:
Step 1 Open the Template Manager. Click Configure, then Template Manager, then Execute.
Step 2 Using the pull-down menu, select the 7206-ENTRY device, not the 7206 device type.
Step 3 Select the "7206-default-entry" template, and click Open.
Step 4 Scroll down a short amount to the section for interface FastEthernet0/0 and change the IP address line as shown.
change: ip address #7206_FE_0_0_IP #7206_FE_0_0_NET_MASK to: ip address #FE_10_FIRST_IP #FE_10_FIRST_NET_MASK
Step 5 Change the Name field at the bottom from "7206-default-entry" to something you prefer such as "7206-default-workaround." Modifying the Description field is optional.
Step 6 Click Save As and then Done.
To use the new custom template:
Step 1 Select your stack in the lower left frame.
Step 2 Click Configure, then Shelf Add, then Execute.
Step 3 Select the 7206 device type.
Step 4 Provide all needed data for the fields that are appropriate to your particular environment, and click Next.
| GUI Label | Actual Router Interface |
|---|---|
FE 1/0 Primary | FE 0/0 |
FE Backdoor | BVI 2 |
Step 5 Provide all needed data for the fields that are appropriate to your particular environment, and click Next.
Step 6 In the Shelf Configuration---Add screen, choose your modified custom template for the field Select a Configuration Template.
Step 7 Make other changes in this screen as needed, then click Next. Proceed as usual.
If you clone the Shelf Status or the Line Statistics screen, and then add a new shelf to a stack, the cloned screen will not contain information about the new shelf. The workaround is to close screens after creating new shelves. [CSCdj79558]
The IP address field in the configuration download screen is not long enough to display long IP addresses. You can still enter long IP addresses, but you might not be able to see all of the digits you type. [CSCdj86068]
If you attempt to add a shelf exceeding the predefined number of shelves in a stack, the shelf will not add to the stack unless you modify the stack definition to increase the number of shelves allowed in this stack.
This does not affect addressing on existing shelves. [CSCdj29369]
During a Shelf Restore, the Preview the configuration file ... button displays the last configuration file for the device. This configuration file might not contain the most current configuration data. However, when APM performs the Shelf Restore, it regenerates the configuration and downloads the new configuration to the device. [CSCdj87210]
The Shelf Address screen calculates the IP address to be used to configure a given device through the Ethernet.
However, if you attempt to modify a shelf's Ethernet IP address, the Shelf Address screen will incorrectly make its calculation of the configuration IP address using the new address although it might not exist yet.
In such a case, you must manually enter the correct Ethernet IP address to use when configuring the device. [CSCdj53948]
When you configure a shelf using Ethernet or FastEthernet, if in the log there is an rcp Permission denied error message, perform the following steps:
Step 1 Use the UNIX command ls -al to check the APMadmin account home directory for the following conditions:
Step 2 If both of the answers are yes, use vi or another text editor to view the contents of the .rhosts file. Check to see if the Ethernet or FastEthernet IP address of the device to be configured is present.
Under certain conditions, a configuration job might not submit correctly despite having correct parameters.
If this occurs, enter the UNIX command ls -l on the directory /opt/CSCOapm/etc. If your APM admin account is APMadmin, then make sure your file ownership and permissions are as follows:
-rwsrwsr-x 1 root other 23272 Aug 8 02:45 APMQ -rwsrwsr-x 1 APMadmin other 9136 Aug 8 02:45 APM_access -rwsrwsr-x 1 root other 9136 Aug 8 02:45 APM_crontab -rwsrwsr-x 1 APMadmin other 11140 Aug 8 02:45 APM_rhosts
If necessary, use the chmod or chown commands to change permissions and ownerships. [CSCdj32971]
Under certain rare conditions, when adding a shelf without really configuring the device, a timeout error condition might occur.
Although the shelf is added properly to the APM system for polling purposes, the output in the Shelf Add Job popup window stops early. After about 10 minutes, the following message appears:
<HTML><HEAD><TITLE>OK</TITLE></HEAD> <BODY><H1>OK</H1> An error has occurred.
To avoid this problem, select Ethernet rather than Terminal Server in the last Shelf Add Device Access Configuration screen. [CSCdj52777]
During the configuration of shelves, or when modifying or deleting a stack, after the user clicks Finish, a popup window displays the status of the job, including its output.
Sometimes, this window might appear without displaying any messages. This happens more often if the user is running more than one Netscape Navigator browser on the same workstation.
Though the popup window freezes, and you cannot see any messages in that window, the configuration job will continue to run. When the job ends, successfully or otherwise, the window will unfreeze, letting the user see all the messages.
If this happens, wait for the main browser window to indicate the status of the ongoing configuration job. [CSCdj47989]
The Submit Shelf Job screen might lose user selections.
You might have selected Ethernet as a device configuration, but if you click the Back button and later return to this screen, your selection of Ethernet will be lost along with any IP address values you entered for the Ethernet port. Instead, Terminal Server will be selected and the default IP addresses will have replaced any customizations you might have made. Reselect Ethernet and reenter any customized IP values. [CSCdj52683]
When modifying a stack from two Router Shelves (offload server shelves) to one, the IP address of the second Router Shelf will be set to blank in the database.
This will stop the poller from polling the stack. To downgrade a dual Router Shelf AccessPath stack to a single Router Shelf configuration, follow these steps:
Step 1 Delete the second Router Shelf.
(a) Select the second Router Shelf.
(b) Click Configure>Shelf Delete>Execute.
(c) Use the displayed data to verify that this is the shelf you want to delete.
(d) Click Next, then Next, then Delete.
Step 2 Change the number of Router Shelves in the stack.
(a) Select the stack.
(b) Click Configure>Stack Modify>Execute.
(c) Change the Number of 7206(s) pulldown menu from 2 to 1.
(d) Click Next six times as you go through the other stack modification screens.
(e) Click Finish. [CSCdj41895]
Any templates placed into the APM file structure manually, that is, without the use of the APM Template Manager, will not be available for editing or viewing in the Template Manager.
Any templates that are copied into the APM directory structure must be viewed or edited using a text editor such as vi. These templates can still be downloaded to the shelves within an AccessPath system. [CSCdj59421]
The Cisco IOS release displayed when you select Shelf>Monitor>Display>IOS Version is the release originally configured for that shelf.
This tool is not meant to provide Cisco IOS image management. It is intended only to show the Cisco IOS release on this shelf when the shelf was created. [CSCdj46782]
This section describes software reports caveats.
When the file env_report is missing or corrupted, the report module will not give any warning in the CSCOapm.report.log file.
If your env_report file is missing or corrupted, you can regenerate the file using the report_admin tool.
To run the Report Scheduler Administration Tool:
Step 1 Go to the Report Scheduler admin directory. Enter:
% cd /opt/CSCOapm/admin
Step 2 Run report_admin. Enter:
% report_admin
Step 3 Select the reports that will be run and the length of time they will be saved by answering the prompts. Press Return to accept the defaults in square brackets.
Enable Traffic Loads reports (y/n)? [y] y
Enable PPS reports (y/n)? [y] y
Enable daily reports (y/n)? [y] y
Enable weekly reports (y/n)? [y] y
Enable monthly reports (y/n)? [y] y

Enable monthly reports (y/n)? [y] y
Daily reports saved for how long (in days)?[31]
Weekly reports saved for how long (in days)?[92]
Monthly reports saved for how long (in days)?[366]
Step 4 You will be shown a summary of the changes you have made. If the summary is acceptable, answer y. If it is not acceptable, answer n and begin this procedure again.
Are these acceptable (y/n)? [y] y
[CSCdj74956]
For certain time ranges, there is a possibility of inaccurate data in the Modem Connection report if a device has rebooted twice in a short period of time (twice in one hour for daily reports, twice in 3 hours for weekly reports, twice in 3 days for monthly reports) during the time range. [CSCdj32971]
This section describes an HP OpenView caveat.
If you delete a shelf, you must manually delete the shelf symbol and object. [CSCdj25841]
