Oracle Database Appliance Space Utilization Issue

 

One of the basic issue when having ODA (Oracle Database Appliance) system is space utilization in /opt mount point.

Recently I was facing the same issue on my Oracle Database Appliance version 19.17.0.0.0 one node, on checking the /opt mount point thoroughly it was found a file “dcs-agent.log” was generating the same log message repeatedly and a file of around 1.5G was being made daily on just one node.

File Location :-

/opt/oracle/dcs/log/dcs-agent.log

 

Error:-

The following is found on the logs:

Analysis:-

After analyzing the logs it was understood that the issue was with a job which was not completed and was still in running, on further checking it was found that this is a known bug of this version in which the connection between ODA clients is lost and the job keeps running.

 

Solution:-

In solution of the error following steps are to be performed.

  1. Run the following all four commands on node1 and node2 respectively to stop the clients.

Note:-

               Run all four commands on node 1 fist then run all four commands on node 2

 

  1. # /opt/zookeeper/bin/zkServer.sh stop
  2. # systemctl stop initdcsagent
  3. # systemctl stop initdcscontroller
  4. # systemctl stop initdcsadmi

 

  1. Now run all four following commands on node1 and node2 respectively to start the clients.

Note:-

               Run all four commands on node 1 fist then run all four commands on node 2

 

  1. # /opt/zookeeper/bin/zkServer.sh status
  2. # systemctl status initdcsagent
  3. # systemctl status initdcscontroller
  4. # systemctl status initdcsadmin
  5. # odacli ping-agent

 

Once the action plan is completed check the log file again it should have stop generating the error and the size increase should also be stopped.
