Testing with Oozie 4.1.0 shows that identifiers (e.g. workflow action names) need to follow the regex ^[a-zA-Z_][\\-_a-zA-Z0-9]{0,38}$, however names (e.g. workflow and coordinator names) do not need to adhere to that regex (e.g. can contain spaces/punctuation) but are limited to 255 chars by Oozie's backing database and are limited to printable ASCII characters.
Creating a workflow with a really long action name results in:
org.apache.oozie.command.CommandException: E0724: Invalid node name, name [action-ppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppp] must be 50 chars or less

Creating a workflow with a very long name results in:
