NetWorker (Linux): Uppgradering till NetWorker 19.13 kan inte konfigurera AUTHC-server

NetWorker-autentiseringstjänsten rapporterar följande fel vid uppgradering till 19.13.x från en tidigare version:

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

Samma fel returneras när du kör AUTHC-konfigurationsskriptet: /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 kräver Java Development Kit (JDK) 17. NetWorker-servern använder Java Runtime Environment (JRE) 1.8, som användes av NetWorker 19.12 och tidigare.

[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

Installera NetWorker Runtime Environment (NRE) 17.0.1 (eller senare) eller Oracle-licensierad JDK 17. NRE är tillgängligt via: https://www.dell.com/support/product-details/en-us/product/networker/drivers

NRE configuration completed

När du har uppgraderat till JDK 17 kör du authc_configure.sh Skript som ska konfigureras 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.

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

Granska NetWorker-servern /nsr/logs/daemon.raw Så här övervakar du att tjänsten startas: NetWorker: Så här använder du nsr_render_log för att återge .raw loggfiler

Problemet som beskrivs i denna KB uppstår även under nya distributioner av 19.13 om JDK 17-kraven inte uppfylls.
