PRGT-00387
An existing upgrade database operation currently in progress from the source Oracle home "{0}" to target working copy "{1}" previously submitted by user "{2}" on node "{3}" running in cluster "{4}".
Cause
An attempt to initiate a patching operation over the grid entity is being rejected because there is an existing "upgrade database" operation currently in progress for the provided target cluster.
Action
Wait until the existing active operation finishes, then retry the command or remove the '-checkdbpatching' option to ignore ongoing Oracle Database patching operations executed using Oracle Fleet Patching and Provisioning (FPP) tool.
