Data Protection Central - ELG ve Monitör, 19.9.0-13 e (IDPA 2.7.6) yükseltme yapıldıktan sonra başlatılamadı

Problem Tanımı:
Integrated Data Protection Appliance sürüm 2.7.6 yükseltmesinin bir parçası olarak DPC sürüm 19.9.0-13'e yükseltildikten sonra ELG ve monitör başlatılamadı:

# /usr/local/dpc/bin/dpc status
Version: 19.9.0-13
 
msm-ui-main: active
msm-monitor: failed
msm-elg: failed
mongod: active
rabbitmq-server: active
nginx: active
dp-iam: active
FIPS: disabled

ELG manuel olarak başlatılamıyor:

# systemctl start msm-elg.service
Job for msm-elg.service failed because the control process exited with error code. See "systemctl status msm-elg.service" and "journalctl -xe" for details.

Elg.out dosyasından, bir Java izin sorunu olduğunu gösterir:

# cat /logs/elg/elg.out
nohup: failed to run command '/usr/bin/java': Permission denied

Ancak, Java manuel olarak düzgün çalışır:

# ls -la /usr/bin/java
lrwxrwxrwx 1 root root 22 Oct 26  2018 /usr/bin/java -> /etc/alternatives/java
# ls -la  /etc/alternatives/java
