Symptoms

NetWorker Authentication Service segnala il seguente errore durante l'aggiornamento a 19.13.x da una versione precedente:

Exception in thread "main" java.lang.UnsupportedClassVersionError: com/emc/brs/auth/util/ServiceConfigurator has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Durante l'esecuzione dello script di configurazione di AUTHC viene restituito lo stesso errore: /opt/nsr/authc-server/scripts/authc_configure.sh

[root@lnx-srvr01 linux_x86_64]# /opt/nsr/authc-server/scripts/authc_configure.sh

Specify the directory where the Java Standard Edition Runtime Environment (JRE) software is installed [/opt/nre/java/latest]:

The installation process will install an Apache Tomcat instance.
For optimum security, EMC NetWorker Authentication Service will
use a non-root user (nsrtomcat) to start the Apache Tomcat instance.
If your system has special user security requirements, ensure that proper
operational permissions are granted to this non-root user (nsrtomcat).
Please refer to NetWorker Installation Guide.

NOTA: Il problema descritto in questo articolo della Knowledge Base si applica anche ai server NetWorker Management Console (NMC) e NWUI (NetWorker Web User Interface) 19.13.

Cause

NetWorker 19.13 richiede Java Development Kit (JDK) 17. Il server NetWorker utilizza Java Runtime Environment (JRE) 1.8, utilizzato da NetWorker 19.12 e versioni precedenti.

[root@lnx-srvr01 linux_x86_64]#  sudo find /usr /opt /lib* -type f -name "java" 2>/dev/null
/opt/nre/java/jre1.8.0_421/bin/java
NOTA: Il documento NetWorker 19.13 Installation Guide descrive in dettaglio i requisiti Java per i componenti di NetWorker. https://www.dell.com/support/product-details/product/networker/docs

Resolution

Installare NetWorker Runtime Environment (NRE) 17.0.1 (o versione successiva) o JDK 17 con licenza Oracle. NRE è disponibile tramite: https://www.dell.com/support/product-details/en-us/product/networker/drivers

Creating the installation log in /opt/nre/logs/install.log.

Performing initialization. Please wait...

NRE configuration completed


Dopo l'aggiornamento a JDK 17, eseguire il comando authc_configure.sh Script da configurare authc:

[root@lnx-srvr01 ~]# /opt/nsr/authc-server/scripts/authc_configure.sh

Specify the directory where the Java Standard Edition Runtime Environment (JRE) software is installed [/opt/nre/java/latest]:

The installation process will install an Apache Tomcat instance.
For optimum security, EMC NetWorker Authentication Service will
use a non-root user (nsrtomcat) to start the Apache Tomcat instance.
If your system has special user security requirements, ensure that proper
operational permissions are granted to this non-root user (nsrtomcat).
Please refer to NetWorker Installation Guide.

The Apache Tomcat will use "lnx-srvr01.networker.lan" as the host name.
The Apache Tomcat will use "9090" as the port number.

The NetWorker Authentication Service requires a keystore file to configure encryption and to provide SSL support.

EMC recommends that you specify a keystore password that has a minimum of six characters.

Do you want to use the existing keystore /nsr/authc/conf/authc.keystore [y]?

Specify password for the existing keystore:
The install will use the existing certificate "emcauthctomcat" for Apache Tomcat.
The install will use the existing certificate "emcauthcsaml" for Authentication Service.

Creating the installation log in /opt/nsr/authc-server/logs/install.log.

Performing initialization. Please wait...


The installation completed successfully.

[root@lnx-srvr01 ~]# systemctl start networker

Additional Information

Il problema descritto in questo articolo della Knowledge Base viene visualizzato anche durante le nuove distribuzioni di 19.13 se i requisiti di JDK 17 non vengono soddisfatti.
