NetWorker (Linux): Při upgradu na verzi NetWorker 19.13 nelze nakonfigurovat server AUTHC

Ověřovací služba NetWorker hlásí při upgradu na verzi 19.13.x z předchozí verze následující chybu:

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

Stejná chyba se vrátí při spuštění konfiguračního skriptu AUTHC: /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.

NetWorker 19.13 vyžaduje sadu Java Development Kit (JDK) 17. Server NetWorker používá prostředí Java Runtime Environment (JRE) 1.8, které používal nástroj NetWorker 19.12 a starší.

[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

Nainstalujte prostředí NetWorker Runtime Environment (NRE) 17.0.1 (nebo novější) nebo JDK 17 s licencí Oracle. NRE je k dispozici prostřednictvím: https://www.dell.com/support/product-details/en-us/product/networker/drivers

NRE configuration completed

Po upgradu na JDK 17 spusťte authc_configure.sh Skript pro konfiguraci 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.

The installation completed successfully.
