NetWorker(Linux): NetWorker 19.13へのアップグレードでAUTHCサーバーを構成できない
Summary: Linux NetWorkerサーバーを以前のリリースから19.13.xにアップグレードすると、AUTHCのインストール中にJavaエラーが報告されます。
Symptoms
以前のリリースから19.13.xにアップグレードすると、NetWorker認証サービスで次のエラーが報告されます。
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構成スクリプトを実行すると、同じエラーが返されます。 /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.

Cause
NetWorker 19.13にはJava Development Kit(JDK)17が必要です。NetWorkerサーバーは、Java Runtime Environment (JRE) 1.8を使用しています。これは、NetWorker 19.12以前で使用されていたものです。
[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
Resolution
NetWorker Runtime Environment (NRE) 17.0.1(またはそれ以降)またはOracleライセンスJDK 17をインストールします。NREは、次の方法で入手できます。 https://www.dell.com/support/product-details/en-us/product/networker/drivers

JDK 17にアップグレードした後、 authc_configure.sh 設定するスクリプト authcが使用するJava Runtime Environmentへのパスを定義します。
[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
NetWorkerサーバーを確認します /nsr/logs/daemon.raw サービスの起動を監視するには、次の手順を実行します。NetWorker:nsr_render_logを使用して.rawログ ファイルをレンダリングする方法
