Administrator tab is not visible for admin user and OneClick is blank

Products

• CA Spectrum
• DX NetOps

Issue/Introduction

Due to linux operating sysystem OS patching our Spectrum primary SSs were rebooted and also two oneclicks were rebooted out of 4.

Now we have an issue with our Oneclick --Administrator tab is not showing 

But on other oneclick URL , all tabs are visible for the same user.

We have restarted the tomcat and webtomcat but no luck.

Environment

Release : All Supported Releases

Component : SPCOCK - Spectrum OneClick

Cause

Rogue tomcat process was running.

Resolution

The OneClick tomcat log file was showing a CORBA bind address in use:

ug 02, 2021 10:31:05.056 - VBrokerCORBAClientHelper: unable to resolve RootPOA: org.omg.CORBA.ORBPackage.InvalidName: org.omg.CORBA.COMM_FAILURE: java.net.BindException: Address already in use (Bind failed)  vmcid: 0x0  minor code: 0  completed: No
Aug 02, 2021 10:31:05.357 - SPC-OCA-10379: An unexpected exception occurred registering watch for user model <user> on Model Domain <host>: exception com.aprisma.spectrum.core.idl.CsCException.CsCSpectrumException

When running a process listing and grep for tomcat there were multiple OneClick java processes running.  There should only be one java process for the OneClick tomcat.

To resolve this:

1.  Stop webtomcat, tomcat, and processd:

$SPECROOT/webtomcat/bin:  ./stopWebTomcat.sh
$SPECROOT/tomcat/bin:  ./stopTomcat.sh
$SPECROOT/lib/SDPM:  ./processd --stop

2.  Run a process listing and see if any java processes are running:

ps -ef | grep -i java

3.  Kill the rogue java process:
./kill -9 <pid>

4. Restart processd which will automatically start Tomcat and WebTomcat:

$SPECROOT/lib/SDPM:  ./processd --start
