NetWorker (Linux): NetWorker 19.13 -versioon päivittäminen AUTHC-palvelimen määrittäminen ei onnistu

NetWorker-todennuspalvelu ilmoittaa seuraavasta virheestä päivitettäessä versioon 19.13.x aiemmasta versiosta:

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

Sama virhe palautetaan AUTHC-määrityskomentosarjaa suoritettaessa: /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 edellyttää Java Development Kit (JDK) 17 -pakettia. NetWorker-palvelimessa on käytössä Java Runtime Environment (JRE) 1.8, jota käytettiin NetWorkerin versiossa 19.12 ja sitä aiemmissa versioissa.

[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

Asenna NetWorker Runtime Environment (NRE) 17.0.1 (tai uudempi) tai Oracle-lisensoitu JDK 17. NRE on saatavilla seuraavilla tavoilla: https://www.dell.com/support/product-details/en-us/product/networker/drivers

NRE configuration completed

Kun olet päivittänyt JDK 17 -versioon, suorita authc_configure.sh Määritettävä komentosarja 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.

Tässä tietämyskannan artikkelissa kuvattu ongelma ilmenee myös uusien 19.13-käyttöönottojen yhteydessä, jos JDK 17 -vaatimukset eivät täyty.
