Unable to start APM WebView, Hi,Unable to start APM WebView

[Legacy User]

Hi,

 

I am unable to start CA APM WebView. I restarted the EM and verified that EM is up and running. I see the below error message.

 

[root@xxxxx bin]# ./WVCtrl.sh start
Using APMHOME: /appintro/Introscope10.5.1.8
Using JAVA_HOME: ../jre
Using EM Host: xxxxx.tolls.dot.state.fl.us
Using EM Port: 5001
Reconnect attempt to EM: 1
Reconnect attempt to EM: 2
Reconnect attempt to EM: 3

 

Please advise.

 

Thanks,

 

Arnab

can you telnet from your WV server to your EM?

Hi Haruhiko,

 

The WV and EM is on the same server. I see the below message when I try to run it. Thanks

Hi Arnab,

What does the output of this command show: 

netstat -na |grep 5001 |grep LISTEN

 

If you edit the IntroscopeWebView.properties file and change the EM hostname property as follows does it allow WebView to start?

introscope.webview.enterprisemanager.tcp.host=xxxxx.tolls.dot.state.fl.us

to

introscope.webview.enterprisemanager.tcp.host=127.0.0.1

 

Thanks

Hi William,

 

Thank you for your excellent advise. I was able to restart WVView after changing to local host.

 

Regards,

I would also check to see if ‘telnet' or ‘netcat|nc' is available in our account's path by running command ‘which (telnet|nc)'. If neither are available, this will prevent you from starting WV.

Disable the checks used by these tools to let the script to continue starting WV.

Thanks Haruhiko! I appreciate your help and support!

I've also been having issues with WebView starting, but my messages are a bit different:

Please check /opt/CA/APM/EM/logs/Introsco peWebViewConsole.log for details. ./WVCtrl.sh start: APM WebView could not be started

 

Then in the MOM Enterprise Manager log there was an issue with the LDAP connection.  This was caused when our LDAP server was shifted during network maintenance.  

 

Appears that the WebView in 10.5.2 is a bit less tolerate of the Mom being busy or having issues.
