How to Redeploy IBM Business Automation Content Analyzer

Steps

1. Undeploy ACA.
   • If ACA is the only product deployed, run:
     • oc delete -f <cr yaml file>
   • If there are other ICP4A products that are deployed, comment out the ca_configuration section header line in the cr yaml and run:
     • oc apply -f <cr yaml file>
2. Wait until Operator deletes the installation and all ACA pods are terminated.
   • oc get pods
3. If a pod still has a status of Terminating after 5 minutes, it might be necessary to force it to be deleted.
   • oc delete pod <pod name> --force --grace-period=0
4. Navigate to the data folder as defined by the data pvc and delete all the files and folders within it.
   • rm -rf *
   • WARNING: Be careful to be in the correct folder before you run any delete command.  Deleting files in other folders can make the system unusable. 
5. Do the same task with the config and log files and folders.  These files and folders don't interfere with redeployments.  However, they are no longer needed and the redeployment is a good opportunity to purge them.
6. Redeploy ACA.  If lines were previously commented out in the cr yaml, uncomment them and run:
   • oc apply -f <cr yaml file>
