Problem Clarification

Cause

Checked the logs.

Customer implemented the patch asgProps-installer-1.0.bsx at Jan24 15:32:58 with success,
 
<134>Jan 24 15:32:58 CDOM-1ST -bash: +09:00 2017 924 1 com.avaya.vsp | 0 HISTORY: PPID=29792 PID=29793 UID=0 md5sum asgProps-installer-1.0.bsx
<134>Jan 24 15:33:16 CDOM-1ST -bash: +09:00 2017 723 1 com.avaya.vsp | 0 HISTORY: PPID=29792 PID=29793 UID=0 sh ./asgProps-installer-1.0.bsx
 
the exit code of asgProps_install.log showns as below:
2017-01-24 15:33:16 INFO: Begin install of asgProps rpms
2017-01-24 15:33:17 INFO: Completed asgProps install return code 0
 
And the tomcat’s logs showed the service restart was successful.
2017-01-24 15:33:23,140|Jan 24, 2017 3:33:23 PM org.apache.catalina.startup.HostConfig deployD. escriptor

2017-01-24 15:33:26,272|log4j: reset attribute= "false".
 
 
Then he did the second patch webconsole-asg-fix-1.0.bsx
<134>Jan 24 15:34:11 CDOM-1ST -bash: +09:00 2017 474 1 com.avaya.vsp | 0 HISTORY: PPID=29792 PID=29793 UID=0 md5sum webconsole-asg-fix-1.0.bsx

And the tomcat’s logs showed the service restart was failed.
2017-01-24 15:34:30,783|Jan 24, 2017 3:34:30 PM org.apache.catalina.startup.HostConfig deployDescriptor
2017-01-24 15:34:30,783|SEVERE: Error deploying configuration descriptor webconsole.xml
2017-01-24 15:34:30,783|java.lang.UnsupportedClassVersionError: com/avaya/vsp/webconsole/system/WebContextListener : Unsupported major.minor version 52.0 (unable to load class com.avaya.vsp.webconsole.system.WebContextListener)
 
In this case, the issue might be caused by the secondary patch. And the kay jar file is named webconsole.jar

Solution

 

It’s related to PSN027045u. Customer applied the patch webconsole-asg-fix-1.0.bsx. After the patching, they cannot browse the webconsole of Cdom. Displayed: “HTTP Status 503 - This application is not currently available”
When running swversion from cdom, java error displayed. “UnsupportedClassVersionError”
 
I can replicate the issue in lab environment on VSP 6.3.7. And I found the issue is due to the new webconsole.jar cannot be compatible after the patching.
 
The temporary fix per I test is to do the copy: cp /root/webconsole.jar.orig /opt/avaya/vsp/tomcat/webapps/webconsole/WEB-INF/lib/webconsole.jar
 
Change the owner of the file as tomcat and give it execution right. The permission should look like
-rwxr--r-- 1 tomcat tomcat 3370989 Jan 30 10:22 /opt/avaya/vsp/tomcat/webapps/webconsole/WEB-INF/lib/webconsole.jar
 
Then restart the tomcat services by “ service tomcat restart”
After restart the tomcat, the web should be able to access. But swversion will still got Java Exception error. The fix is to follow below instructions:
Modify /opt/avaya/vsp/bin/swversion.impl
change
appendClassPath `find $WEBCONSOLE_LIB -name *.jar`
to
appendClassPath `find $WEBCONSOLE_LIB -name '*.jar'`
 
and change
appendClassPath `find $TOMCAT_LIB -name *.jar`
to
appendClassPath `find $TOMCAT_LIB -name '*.jar'`
 
After the change, everything looks good then.
 
And I also tested the patch on VSP6.4, after the patching, everything looks fine without any issue. The PSN might be applicable to VSP 6.4 only. But the PSN mentioned Avaya Aura® System Platform, Releases 6.3.x, 6.4
 
Got confirmation from VSP tier4, the PSN is applicable to VSP 6.4 only.
