Symptoms

NetWorker kimlik doğrulama hizmeti, önceki bir sürümden 19.13.x e yükseltme yaparken aşağıdaki hatayı bildirir:

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

AUTHC yapılandırma komut dosyası çalıştırılırken de aynı hata döndürülür: /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.

NOT: Bu KB de özetlenen sorun, 19.13 NetWorker Yönetim Konsolu (NMC) ve NetWorker Web Kullanıcı Arayüzü (NWUI) sunucuları için de geçerlidir.

Cause

NetWorker 19.13, Java Development Kit (JDK) 17 gerektirir. NetWorker sunucusu, NetWorker 19.12 ve önceki sürümleri tarafından kullanılan Java Runtime Environment (JRE) 1.8'i kullanıyor.

[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
NOT: NetWorker 19.13 Kurulum Rehberi, NetWorker bileşenleri için Java Gereksinimlerini ayrıntılı olarak açıklar. https://www.dell.com/support/product-details/product/networker/docs

Resolution

NetWorker Runtime Environment (NRE) 17.0.1 (veya üzeri) veya Oracle lisanslı JDK 17'yi yükleyin. NRE şu yollarla kullanılabilir: https://www.dell.com/support/product-details/en-us/product/networker/drivers

[root@lnx-srvr01 17.0.1]# /opt/nre/nreconfig.sh

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

Performing initialization. Please wait...

NRE configuration completed


JDK 17'ye yükselttikten sonra, authc_configure.sh Yapılandırılacak komut dosyası 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

Bu KB de özetlenen sorun, JDK 17 gereksinimleri karşılanmazsa 19.13 ün yeni dağıtımları sırasında da ortaya çıkmaktadır.
