La integración de NetWorker VMware Protection se configura con el vProxy Appliance. La variable emcauthctomcat se puede quitar cuando se actualiza la instalación de Java Runtime Environment (JRE) en NetWorker Server. El plug-in de vSphere Web Client no se puede conectar a NetWorker Server y presenta el siguiente error:

Cause

La instalación de JRE ya no tiene la autenticación Tomcat de NetWorker (emcauthctomcat) certificado utilizado por el plug-in de respaldo y recuperación de VM de vSphere Web Client. 

Resolution

El certificado emcauthctomcat se debe importar a la configuración del almacenamiento de claves de JRE de Java. Esta es una visión general para comprobar si el certificado existe e importarlo.

  1. Abra un símbolo del sistema de Windows o una sesión de terminal de Linux en NetWorker Server.
  2. Cambie al directorio de instalación de JRE de Java. El directorio cambia según la versión de JRE de Java instalada.  
Ejemplo de rutas de instalación para JRE 1.8.0_151
  • Windows: C:\Program Files\Java\jre1.8.0_151\bin>
  • Linux: /usr/java/jre1.8.0_151/bin
Ejemplo de instalación del entorno de tiempo de ejecución de NetWorker (NRE):
  • Windows: C:\Archivos de programa\NRE\java\jre#.#.#_####\bin
  • Linux: /opt/nre/java/latest/bin
  1. Utilice la utilidad de línea de comandos keytool para validar si el certificado no existe en el almacenamiento de claves cacerts de Java JRE:
    • Windows:
keytool -list -storepass changeit -keystore ..\lib\security\cacerts | findstr emc
  • Linux:
keytool -storepass changeit -list  keystore ../lib/security/cacerts | grep emc
  1. Utilice la utilidad de línea de comandos keytool para importar el emcauthctomcat certificado:
    • Windows:
keytool -importcert -storepass changeit -trustcacerts -alias emcauthctomcat -file "C:\Program Files\EMC NetWorker\nsr\authc-server\tomcat\conf\emcauthctomcat.cer"  -keystore ..\lib\security\cacerts
  • Linux:
keytool -importcert -storepass changeit -trustcacerts -alias emcauthctomcat -file /nsr/authc/conf/emcauthctomcat.cer -keystore ../lib/security/cacerts 
  1. Utilice la utilidad de línea de comandos keytool para validar si el certificado ahora existe en el almacenamiento de claves cacerts de Java JRE:
    • Windows:
keytool -list -storepass changeit -keystore ..\lib\security\cacerts | findstr emc
  • Linux:
keytool -storepass changeit -list  keystore ../lib/security/cacerts  | grep emc
