Last updated on DECEMBER 01, 2021

Applies to:

Oracle Database Appliance Software - Version 18.1 and later
Linux x86-64


Zookeeper failed to start after 'update-server' from 18.5 to 18.7.
The subsequent pre-checks for 'update-storage' will fail with the following error.


# odacli list-jobscreate-prepatchreport -st -v
DCS-10001:Internal error encountered: DCS servers are not available on all nodes, pre-checks will not be successful.

 After reboot server, zookeeper didn't start automatically.

 # ps -elf | grep -i zoo

 0 S root 44606 44042 0 80 0 - 25845 pipe_w 09:18 pts/0 00:00:00 grep -i zoo

However zookeeper can be started manually.

# /opt/zookeeper/bin/ start
ZooKeeper JMX enabled by default
