Rollback Exadata Patches

Should a rollback be required after successfully deploying a patch on your Exadata targets, you can do that and retry patches using EMCLI commands.

Before you consider performing a rollback, verify if the patch update procedure is successful or not. Following the instructions at Track, Fix and Resume Operations in Enterprise Manager Database Lifecycle Management Administrator's Guide.

Topics:

To retry an operation, see Exadata Fleet Maintenance Patching Operations.

 -purpose="ROLLBACK_EXADATA_SOFTWARE" 
-target_list="Cel1,Cell2" 
-target_type="oracle_exadata" 
-input_file="data://home/user_name/fppinstallfest/updateExadata.prop"

EMCLI command format for Switch:

emcli db_software_maintenance
